Importance of Information Technology (IT) | My Essay Point

Case#x02013;Control Study of Blood Lead Levels and essay information Attention Deficit Hyperactivity Disorder in Chinese Children. Attention deficit/hyperactivity disorder (ADHD) and lead exposure are high-prevalence conditions among children. Our goal was to investigate the association between ADHD and blood lead levels (BLLs) in human cover letter with no experience, Chinese children, adjusting for known ADHD risk factors and potential confounding variables. We conducted a pair-matching case#x02013;control study with 630 ADHD cases and 630 non-ADHD controls 4#x02013;12 years of age, matched on technology, the same age, sex, and socioeconomic status. The case and resources cover no experience control children were systematically evaluated via structured diagnostic interviews, including caregiver interviews, based on essay technology, the Diagnostic and Statistical Manual of Mental Disorders , 4th ed., revised criteria (DSM-IV-R). We evaluated the association between BLLs and ADHD using the Pearson chi-square test for categorical variables and the Student t -test for continuous data. We then performed conditional multiple variables logistic regression analyses with backward stepwise selection to predict risk factors for ADHD. There was a significant difference in resources cover letter, BLLs between ADHD cases and controls. ADHD cases were more likely to essay information and development have been exposed to lead during childhood than the non-ADHD control subjects, with adjustment for other known risk factors [children with BLLs #x02265; 10 #x003bc;g/dL vs. Past Writing 1? #x02264; 5 #x003bc;g/dL; OR = 6.0; 95% confidence interval (CI) = 4.10#x02013;8.77, p #x0003c; 0.01; 5#x02013;10 #x003bc;g/dL vs.#x02264; 5 #x003bc;g/dL, OR = 4.9; 95% CI = 3.47#x02013;6.98, p #x0003c; 0.01]. Technology? These results were not modified by age and essay ib tok sex variables.

This was the largest sample size case#x02013;control study to date to study the association between BLLs and ADHD in Chinese children. ADHD may be an additional deleterious outcome of and development lead exposure during childhood, even when BLLs are #x0003c; 10 #x003bc;g/dL. Attention deficit hyperactivity disorder (ADHD) is one of the most common childhood psychiatric disorders, characterized by uwa essay writing, developmentally inappropriate levels of inattention, impulsivity, and hyperactivity [American Psychiatric Association (APA) 2000; Biederman and Faraone 2005; Rappley 2005; Remschmidt 2005]. Prevalence of ADHD in essay information technology and development, children has been reported to be 3#x02013;8% worldwide (Froehlich et al. 2007; Leung et al. 1996; Remschmidt 2005). Homework? Children who have ADHD are at increased risk for conduct disorder, antisocial behavior, and drug abuse later in life (Satterfield et al. 2007).

Moreover, the costs associated with their medical care and information education are substantial (Leibson et al. 2001). Although the causes of ADHD remain unclear, both genetic and environmental factors are thought to influence the kennedy rice speech etiology of ADHD (Banerjee et al. 2007; Biederman and Faraone 2005; Castellanos and information technology and development Tannock 2002; Millichap 2008; Remschmidt 2005; Swanson et al. 2007). Family, twin, and adoption studies have demonstrated high heritability, and various polymorphisms of dopamine-related genes have been found to increase susceptibility to ADHD (Castellanos and Tannock 2002; Durston 2003; Khan and Faraone 2006). Human Resources Cover No Experience? Furthermore, many environmental risk factors and potential gene#x02013;environment interactions have also been shown to increase the risk for the disorder (Banerjee et al. 2007; Biederman and Faraone 2005; Millichap 2008; Thapar et al. 2007).

Indeed, there is growing interest in studying the essay technology relationship between chronic heavy metal toxicity, including lead exposure, and ADHD (Braun et al. Rice Speech? 2006; Konofal and Cortese 2007; Millichap 2008; Nigg et al. 2008). Lead is one of the well-established environmental poisons, and its general toxic effects, particularly in children, continue to be a major public health issue worldwide [American Academy of Pediatrics (AAP) 2005; Lidsky and Schneider 2003; Needleman 2004]. It is information and development well known that lead can cause cognitive impairment and correlate with decreased IQ scores and impaired attention (Canfield et al. 2003; Koller et al. 2004), and rice speech increased BLLs were associated with higher distractibility and impulsiveness scores in the affected children (Needleman 1993). The World Health Organization (WHO) and the U.S.

Centers for Disease Control and Prevention (CDC) recommended that child blood lead levels (BLLs) not exceed 10 #x003bc;g/dL (CDC 1991; WHO 1995). As a result of rapid industrialization in China, it is estimated that tens of millions of children 1#x02013;18 years of information technology age have BLLs #x02265; 10 #x003bc;g/dL (Huo et al. 2007; Ren et al. 2006; Wang and Zhang 2006). Cleopatra? Furthermore, several recent studies have shown that cognitive deficits and behavioral problems in children still exist even with BLLs #x0003c; 10 #x003bc;g/dL (Binns et al. 2007; Braun et al. 2006; Canfield et al. 2003; Koller et al. 2004). Early studies have documented an association between dentine lead, whole-tooth lead, hair lead, and symptoms of inattention (Bellinger et al.

1994a, 1994b; Fergusson et al. Essay And Development? 1993; Needleman and Leviton 1979; Needleman et al. 1979; Tuthill 1996), and subsequent studies showed that lead exposure can cause attention deficit disorder and impulsivity (Brockel and papers writing 1 Cory-Slechta 1998; Burns et al. 1999; Eppright et al. 1997; Kahn et al. 1995; Minder et al. 1994; Silva et al. 1988; Thomson et al.

1989; Wasserman et al. And Development? 1998, 2001). 1? However, these studies may not be conclusive. First, few studies have investigated the essay information technology and development effect of resources cover letter with no experience lead exposure on ADHD formally diagnosed with the established criteria in International Classification of Diseases, 10th Revision (ICD-10) (WHO 2007) or in Diagnostic and information technology and development Statistical Manual of Mental Disorders, 4th ed., revised (DSM-IV-R; APA 2000) (Burns et al. 1999; Eppright et al. 1997; Silva et al.

1988). Second, most studies were limited by small sample size, and some studies lacked sufficient control of confounding factors (Bellinger et al. 1994b; Minder et al. 1994). Third, early studies involved children who had higher BLLs than the levels seen in contemporary children (Needleman and Leviton 1979; Wasserman et al. 1998) and thus may not be directly relevant to children with lower levels of lead exposure. In addition, there is human cover no experience no investigation of essay technology and development lead exposure and ADHD in Chinese children.

Therefore, in an effort to evaluate the association between BLLs and the risk for ADHD in Chinese children, we performed a case#x02013;control study involving large samples of children 4#x02013;12 years of age. We also considered known potential variables in cleopatra antony essay, the etiology of technology ADHD, such as delivery characteristics, perinatal factors, parental psychosocial factors, and prenatal exposure to and mark antony essay tobacco and alcohol. This study was designed as a pair-matching case#x02013;control study. ADHD subjects were consecutively recruited from essay information technology and development children coming for initial or follow-up assessment from October 2003 to August 2007 in two pediatric clinics at the Anhui Provincial Children#x02019;s Hospital and kennedy the Institute of Anhui Traditional Chinese Medicine in essay and development, Anhui Province, People#x02019;s Republic of we have homework China. Essay Technology And Development? The two major hospitals served the same local population in Anhui province and accepted referrals from all administrative districts within the province. All ADHD (ICD-10 codes F90, 208#x02013;210) subjects were children of Chinese Han nationality 4#x02013;12 years of age at the time of investigation and had a lifetime medical history that fully met the DSM-IV-R criteria (APA 2000; Su et al. 2001) for ADHD. The DSM-IV-R diagnostic criteria had been previously translated into essay ib tok Chinese, and technology the reliability for the ADHD diagnosis was previously assessed (Su et al. 2001). The diagnoses of ADHD were derived from kennedy rice a structured diagnostic interview based on Schedule for Affective Disorders and Schizophrenia for School-Age Children (K-SADS-E) (Ambrosini 2000), which was modified to assess DSM-IV-R criteria and incorporate parents#x02019; and teachers#x02019; reports of behavioral symptoms, clinical observation of essay technology and development behavior, the Aberrant Behavior Checklist (Aman and Singh 1986), and tests of attention such as the Conners#x02019; Continuous Performance Test (Homack and Riccio 2006).

The interviews were performed in ielts past writing task 1, our outpatient clinic and administered by raters (trained research assistants) to children, one of their parents, and their teachers. All the raters, from essay and development two involved pediatric clinics, have postgraduate degrees in psychology and had been trained to uwa essay writing high levels of interrater reliability. Essay Information Technology And Development? We computed #x003ba; coefficients of agreement between all the speech raters and three experienced board-certified child psychiatrists who listened to audio taped interviews made by the raters. Based on 120 interviews, the median #x003ba; was 0.87; #x003ba; was 0.95 for ADHD. Children with identifiable perinatal insults, autism, Asperger syndrome, other pervasive developmental disorders (ICD-10 codes F84.0#x02013;F84.9, 308.0), and mental retardation (ICD-10 codes F70#x02013;F79, 312#x02013;315) were excluded. The non-ADHD controls were randomly selected from computerized lists of outpatients admitted for acute upper respiratory infection at essay information the same two pediatric medical clinics during the daytime and during the same study period.

By the pair-matched design, each ADHD case and control set had the same sex, the same age (difference between birthdays within 6 months), and almost the uwa essay same level of socioeconomic status (SES). The controls were given the same full diagnostic assessment as the ADHD cases and essay technology and development screened only for the absence of ADHD without exclusion of any other diagnosis except for the same exclusion criteria applied to cases. SES is measured by poverty-to-income ratio (PIR), and PIR is the ratio of family income to the poverty threshold for the year of the interview. Low SES was defined as having PIR values #x0003c; 1 in past task, our analysis and high SES as having PIR #x0003e; 3. The others were regarded as middle SES. The study was approved by our institutional review boards and complied with all applicable requirements of the United States. The parents of all the children in this study provided written informed consent at enrollment. Blood samples (2 mL/child) were collected in and development, heparinized syringes. Lead concentrations were measured by anodic stripping voltametry through a blood lead analysis instrument (3010B; ESA Laboratories, Inc., Chelmsford, MA, USA) after the cover with no experience blood samples were digested with an organic tissue solubilizer.

The limit of essay detection was 1.0 #x003bc;g/dL. No detectable values were given values of 0.70 (1.0 divided by the square root of 2). Essay Ib Tok? Lead values were calculated as the essay technology and development means of four analyses of human letter each sample. Epidemiologic studies have shown that male sex, low SES, and essay information young age are associated with a raised prevalence of ADHD. Moreover, its prevalence falls with age (Biederman and Faraone 2004; Doyle 2004; Scahill and Schwab-Stone 2000).

To address these important confounding factors, we employed a pair-match design on age, sex, and we have homework SES; thus, the stratified control subjects were at and development risk at the same sex, age, and SES. In addition, we considered multiple covariates and potential confounders for the association of uwa essay writing lead exposure and ADHD in our study. They were based on established predictors of child behavioral problems and those widely used in studies of pediatric lead exposure (Banerjee et al. Essay Technology? 2007; Biederman and Faraone 2005; Linnet et al. 2003; Mick et al. Ielts Writing Task 1? 2002; Millichap 2008; St Sauver et al. 2004; Swanson et al. Essay? 2007; Wasserman et al. 2001). Antony Essay? The following variables were used: family history of ADHD (ADHD in parents and siblings, diagnosed by psychiatrists, obtained from information technology and development clinical reports), household composition (normal: child lives with biological parents; single: child lives with only one parent; or recombined: child lives in remarried family), maternal tobacco use during pregnancy (at least one cigarette per day during the human resources with no experience last trimester), maternal drinking during pregnancy (at least two glasses per information and development, week during the entire pregnancy), labor complications, cesarean delivery, perinatal distress [low birth weight and admission to a neonatal intensive care unit (NICU) as markers], parents#x02019; age at childbirth, and parents#x02019; education. Because all the cases recruited were of Chinese Han nationality, the variable of human no experience ethnic origin could not be used in our analysis.

These variables were obtained from clinical records or questionnaires completed by direct interview of the parents. Study factors were defined as binary variables or categorical variables. For example, maternal smoking and essay drinking habits during pregnancy were recorded as binary variables#x02014;that is, drinker or nondrinker, cigarette smoker or nonsmoker. We analyzed some continuous potential risk factors as categorical variables according to cut points suggested by the literature. For example, low birth weight is typically defined as #x0003c; 2,500 g (St Sauver et al. 2004). Maternal and paternal age were analyzed as three categories (St Sauver et al. 2004): #x0003c; 20 years, 20#x02013;30 years, and #x0003e; 30 years of age. Maternal and paternal education were analyzed as #x02264; 9 years of compulsory education, high school education (9#x02013;12 years), or some college or advanced training (#x02265; 12 years). The association between BLLs and ADHD was evaluated using the Pearson chi-square test for categorical variables and the Student t -test for continuous data.

We also performed a conditional logistic regression analysis with a binary outcome of ADHD in relation to BLLs, adjusting for other potential confounding factors (Hosmer and Lemeshow 2000). In the regression model, BLLs were analyzed as an ordered categorical variable and recorded as three categories: #x02264; 5 #x003bc;g/dL, 5#x02013;10 #x003bc;g/dL, and #x02265; 10 #x003bc;g/dL. We then performed a conditional logistic regression analysis with backward stepwise procedures based on essay ib tok, the maximum partial likelihood estimates to construct a final best-fit logistic regression models to identify predictors of risk for ADHD among known risk factors and BLLs. Technology And Development? We estimated odds ratios (ORs) and 95% confidence intervals (CIs) for differing levels of exposure. All statistical tests were considered to be significant at an alpha level of 0.05 on a two-tailed test and cleopatra antony performed with the statistical software SPSS version 15.0 (SPSS Inc., Chicago, IL, USA). The analysis included 630 ADHD cases and information and development 630 non-ADHD control subjects matched by essay, age, sex, and SES. There were 434 sets of boys and 196 sets of girls. The average ages were 7.9 #x000b1; 2.1 years.

The mean BLLs were 8.77 #x000b1; 3.89 #x003bc;g/dL in the ADHD group and 5.76 #x000b1; 3.39 #x003bc;g/dL in the control group. The ADHD group had higher BLLs ( p #x0003c; 0.05, see Table 1 ). There was no significant difference in BLLs between males and females. Figure 1 shows BLL distribution and cumulative distribution of technology and development ADHD children and controls. Only 10.1% of rice speech non-ADHD children had BLLs #x0003e; 10 #x003bc;g/dL, whereas this percentage increased significantly to 24.4% in information, ADHD children. (#x003c7; 2 = 237, p #x0003c; 0.01). In addition, 49.8% of uwa essay non-ADHD children had BLLs #x0003e; 5 #x003bc;g/dL, whereas of the essay information technology and development ADHD cases, 74.7% had BLLS #x0003e; 5 #x003bc;g/dL (#x003c7; 2 = 116, p #x0003c; 0.01). Additional information in demographic and the distribution of risk factors are shown in Table 2 . We performed a conditional multivariate logistic regression analysis with all variables (BLLs and and mark all risk factors) simultaneously included in the same model to adjust for essay information technology and development, each other. We found that the ADHD cases were significantly associated with higher BLLs (OR = 5.19, p #x0003c; 0.01 for children with BLLs 5#x02013;10 #x003bc;g/dL; OR = 7.15, p #x0003c; 0.01 for ielts past papers 1, with BLLs #x02265; 10 #x003bc;g/dL, using the essay information technology and development sample with BLLs #x02264; 5 #x003bc;g/dL as referent) and writing family history of ADHD (OR = 4.54, p #x0003c; 0.01, compared with the sample without familial ADHD history). The risk for ADHD decreased as the mother#x02019;s education level increased (OR = 0.69, p = 0.017, using the sample of #x02264; 9 years maternal education as referent). The analysis also found an association between ADHD and essay maternal smoking during pregnancy, but the task 1 p- value is near the significant threshold (OR = 4.04, p = 0.047). The remaining confounding variables in our analysis were not associated with ADHD status ( Table 2 ). To eliminate multivariable interaction and multicollinearity, we then performed a backward stepwise logistic regression based on the maximum partial likelihood estimates.

In the essay technology and development final best-fit model, the cover association between ADHD and maternal smoking during pregnancy was excluded, but ORs for the associations between ADHD and family history of ADHD, maternal education levels, and BLLs were largely unchanged from estimates obtained in the original model used in Table 2 ( Table 3 ). We also performed a conditional multivariate stepwise logistic regression analysis stratified by sex and age. Essay Information Technology? As with the total sample, ADHD cases were significantly associated with higher BLLs than the papers lower BLLs in all subdefinitions ( Table 4 ), which indicates that increased risk for ADHD associated with BLLs is not modified by age and sex. We examined the effect of BLLs in ADHD cases and non-ADHD controls with adjustment for essay technology and development, most other known risk factors in Chinese children 4#x02013;12 years of age. We found ADHD cases were more likely to have been exposed to lead. The children with BLLs #x0003e; 10 #x003bc;g/dL had 4.1- to 8.7-fold higher risk for ADHD.

Even when their BLLs were under the recommended level but #x0003e; 5 #x003bc;g/dL, the homework risk also showed a 3.5- to 7.0-fold increase. Family history of ADHD was another positive high-risk factor. Decreased risk for ADHD was associated with higher maternal education. Lead may play important roles in information technology, the etiology of ADHD. Recently, Braun et al. (2006) analyzed data from a U.S population-based sample and cleopatra and mark concluded that prenatal tobacco exposure and environmental lead are risk factors for ADHD; they found 4.1-fold increased odds of ADHD with increased BLLs. Our work confirmed this finding in the referred sample that relied on information technology, the DSM-IV-R criteria. In addition, Nigg et al. (2008) reported that low-level lead exposure was associated with formal clinical diagnostic ADHD by uwa essay, DSM-IV-R criteria in a community sample in the United States, where regulations have reduced the incidence of lead poisoning and the current population average of lead levels is essay information and development relatively lower.

This is human resources cover with no experience consistent with our finding that the essay risk of ADHD was associated with low lead exposures (#x0003c; 10 #x003bc;g/dL) in Chinese children. Some studies documented varying behavioral effects of lead exposure in cleopatra antony, males and essay information and development females (Burns et al. 1999; Ris et al. 2004). However, in we have, our study, sex and age did not modify the essay information relationship between BLLs and ADHD.

Further studies investigating how neurobehavioral outcome varies with sex and past papers task age may be required. In our study, the absence of a statistically significant association between maternal smoking and ADHD was unexpected, in information technology and development, contrast to previous reports (Braun et al. Uwa Essay? 2006; Linnet et al. 2003; Swanson et al. 2007). The reason might be that, in China, few women smoke during pregnancy and throughout life, which limits the statistical power in information technology and development, detecting a significant difference. Another reason might be that smoking and writing drinking variables of the mother were recorded as a dichotomy in our study, and the threshold to define the and development variables may underreport in utero smoke and alcohol exposure. Human Resources With No Experience? This potential misclassification might underestimate the true association between pregnancy smoking and essay information and development ADHD. Our study found higher maternal education was associated with decreased risk for ADHD.

This result is consistent with previous work, which indicated that low maternal education, low SES, and single parenthood are important adverse factors for ADHD (Biederman and we have Faraone 2005; Millichap 2008; St Sauver et al. 2004). Apart from environmental risk factors for ADHD, our current report indicated that children with a family history of ADHD were more likely to be diagnosed with ADHD. It is also consistent with previous work, which showed that ADHD is transmitted in families (Biederman and Faraone 2002, 2005; Millichap 2008). Although our study showed the association between lead and ADHD, we cannot explain clearly the mechanism that underlies the relationship. As for essay, the etiology of ADHD, dopamine system dysfunction has important effects (Biederman and Faraone 2002; Swanson et al. 2007). And Mark Essay? There is extensive evidence that lead alters midbrain/striatal dopamine functioning as well as gene expression in the striatum (Cory-Slechta 1995; Kala and Jadhav 1995; Szczerbak et al. 2007), so the information technology neurotoxic effect of lead on the dopaminergic neurotransmitter system may be implicated in the pathway to ADHD. Lead exposure could represent a hidden major effect on ADHD incidence via genotype by environmental interaction (Swanson et al. 2007).

The strengths of papers task 1 this study are as follows: a ) Our sample size was the largest to date in case#x02013;control studies to investigate BLLs and ADHD. b ) The ADHD diagnosis was made through an extensive clinical evaluation based on essay, the DSM-IV-R diagnostic instrument and performed by child and adolescent psychiatrists. Essay Ib Tok? c ) The investigators matched the information cases and papers writing controls on potentially important aspects such as age, sex, or SES. Essay Information Technology? This is important because lead levels are highest among younger children compared with adolescents, and ADHD is of higher prevalence among children of elementary and middle-school age. This study suggests that there is a link between ADHD and BLLs, and and mark antony the results reinforced findings from previous studies (Braun et al. 2006; Nigg et al. 2008). If on further inquiry these associations are found to be causal, lead exposure may represent a modifiable risk factor for this common psychiatric condition of childhood.

Considering that ADHD typically starts in essay information, early childhood and that lead poisoning is one of the most common and entirely preventable pediatric problems (AAP 2005; CDC 1991), strategies in uwa essay writing, public health must focus on practicing primary and secondary prevention of lead exposure in children. Essay Information? For example, clinicians should alert parents to potential adverse outcomes of lead associated with this disorder. In addition, routine screening for lead exposure may be needed so that if ADHD symptoms emerge, they can be managed at an early stage. Moreover, BLLs #x0003c; 10 #x003bc;g/dL also indicated a risk factor. This may suggest that the lower standard may effectively protect children from the harmful effects of kennedy speech lead, which is consistent with previous investigations (AAP 2005; Canfield et al. 2003; Surkan et al. 2007). Some studies (Ruff et al.

1993; Tong et al. 1998) found an association between declining BLLs and essay information and development improved cognitive test scores, independent of uwa essay writing whether iron or chelation therapy was administered. However, other works (AAP 2005; Canfield et al. 2003) indicated that the damage caused by essay technology, blood lead exposure is irreversible. Further epidemiologic studies and rigorous randomized controlled trials are needed to determine whether chelation therapy or removal of possible lead exposure sources might help children with ADHD.

This study has several limitations. First, temporality between high BLLs and ADHD could not be ascertained definitely in this case#x02013;control design. It is possible that hyperactive children ingest more lead rather than that lead causes hyperactivity. Should? Therefore, further studies with serial lead measurements, even from the antenatal to the postnatal period, and more continuous measures of ADHD symptoms or of specific underlying neurobehavioral domains may be required to document the temporal relationship between lead exposure and development of ADHD. Second, some might argue that concurrent blood lead tests are not an essay adequate biomarker of a child#x02019;s lifetime exposure. However, recent studies indicate that concurrent BLLs are a stronger predictor of lead-associated IQ decrements than blood lead measured during early childhood (Lanphear et al. 2005). Third, recall bias is uwa essay writing one of the essay technology and development problems of the ielts task 1 case#x02013;control study. In this study, the main variable of essay information and development interest was the BLLs, which were objectively measured.

However, other variables such as in utero tobacco and alcohol exposure may be susceptible to recall bias. Fourth, the cohort was not a random population sample, so potential selection biases cannot be fully ruled out. In addition, because all our sample was Chinese Han, no children living in papers task, foster families were included, and none of the information and development sample had health insurance, our results may not generalize to cleopatra and mark essay children with different socioeconomic or ethnic backgrounds. Finally, it is interesting that Nigg et al. Essay Information? (2008) found a significant relationship between combined-type ADHD and past writing task 1 low-level lead exposure but not predominantly inattentive type and lead exposure. Information And Development? However, we were unable to do analogous analyses by subtype because of the resources cover constraints of the study matching scheme.

This hospital-based case#x02013;control study suggests a strong relationship exists between ADHD and lead exposure, even low-level lead exposure (#x0003c; 10 #x003bc;g/dL BLL), in Chinese children. If this finding is confirmed in future studies, the potential to essay information prevent ADHD by reducing childhood lead exposure should be considered.

Custom Cancer Immunotherapy essay paper. Immunotherapy, also called biotherapy or biological therapy, is essay technology a form of cancer treatment that utilizes the body’s immune system to fight off cancer. Although the action of cancer immunotherapy is not certainly known, there are three possible ways in which researchers believe it works. These include stopping or slowing the growth of cancer cells; stopping cancer from spreading to essay ib tok other body parts; and assisting the immune system to be more efficient in eradicating cancerous cells. Essay Information. The basis of cancer immunotherapy is boosting the body’s immune system to fight off cancer; sounds easy and essay ib tok, logical in essay concept. Unfortunately, like most things in human cover no experience life, the actual scenario is far more complicated, and the pursuit of effective cancer immunotherapy has taken a relatively long time. However, immense progress has been made in the last decade. The fundamental premise for essay technology and development cancer immunotherapy encompasses enhancement of the body’s immune system to fight off cancer. Traditional methods of treating cancer such as radiation, chemotherapy and cleopatra and mark antony, surgery have obvious limitations. Surgery would not be effective in widespread or disseminated diseases, while chemotherapy causes adverse effects on normal cells in and development the process of killing cancer cells. Therefore, a treatment modality enhancing and utilizing the immune system to essay ib tok fight off or prevent cancer is an attractive and sound concept; hence, the essay and development, fundamental premise of human resources cover no experience cancer immunotherapy.

There is a common belief that the failure of the body’s “immune surveillance” is the key contributory cause of cancer. In addition, there is a lack of enough evidence that, in many cancer patients, the essay and development, immune system slows down the spread and growth of tumors. This means that we require a competent immune system to kennedy prevent cancer from information technology and development, spreading once it has started. Cancer immunotherapy can be done through either stimulating the immune system or transferring T-cells or antibodies from an outside source. Today, immunotherapy involving antibodies and certain cytokines has become part of standard cancer treatment. Monoclonal antibodies and cleopatra and mark, cytokines used in cancer immunotherapy are, however, not referred to as medication or drugs, but are labeled as Biological Immune Response Modulators, BIRMs (Charles, Travers, Walport, Shlomchik, 2001). Essay And Development. There are several types of cancer immunotherapy, including monoclonal antibodies, cancer vaccines, and non-specific immunotherapies.

Monoclonal antibodies are laboratory-made. They act like antibodies or part of the body’s immune system to human letter no experience fight off diseases. They are injected into the body, intravenously, and work by targeting protein molecules on the surface of cancer cells or antigens that support cancer cell growth. Essay And Development. After monoclonal antibodies attach to cancer cells, they perform several roles. Kennedy. First, they may allow the immune system to destroy the cancer cell. Technology And Development. Since the immune system does not always distinguish cancer cells, a monoclonal antibody can be directed to attach itself to past papers task 1 certain parts of essay information and development a cancer cell. This makes it easier for the body to find and destroy the essay ib tok, cancer cell. Second, the monoclonal antibodies can prevent cancer cells from growing rapidly. Chemical compounds in the body referred to as growth factors attach themselves to cell surfaces and signal cell growth. Some cancerous cells make additional copies of the growth factor receptor making cancer cells grow faster than normal cells (Weiner, Dhodapkar, Ferrone, 2009).

Monoclonal antibodies block these receptors and prevent the essay information technology, growth signal from getting through cell membranes. In addition, monoclonal antibodies can also deliver radiation directly to human with cancer cells. Without damaging healthy cells, monoclonal antibodies carry tiny radioactive particles directly to cancer cells. Researchers believe that these radioactive particles deliver low level radiation over a long duration. This forms a high-dose external radiation (radiation from a machine outside the body). Tositumomab (Bexxar) and Ibritumomab (Zevalin), for example, are used in the treatment of non-Hodgkin lymphoma.

Monoclonal antibodies also can be used to diagnose cancer. Since they can carry radioactive particles with the use of special cameras, they can help to diagnose cancers such as prostate, ovarian and colorectal. Monoclonal antibodies are also used by pathologists to determine the and development, type of cancer a patient might have had after his or her tissue is removed. Moreover, monoclonal antibodies carry powerful drugs to cancer cells directly. Once the monoclonal antibody attaches itself to a cancer cell, the cancer treatment drug that it is carrying enters the cancer cell and we have homework, killsit without damaging other healthy cells. A good example is Gemtuzumab (Mylotarg), which used in the treatment of acute myeloid leukemia (AML).

Several therapeutic monoclonal antibodies are approved by the Food and Drug Administration (FDA) for human use. These include Alemtuzumab, Bevacizumab, Cetuximab, Gemtuzumab ozogamicin, Rituximab and Trastuzumab. Alemtuzumab is an anti-CD52 monoclonal antibody used for the treatment of the most frequent form of leukemia in Western countries called Chronic Lymphocytic Leukemia, CLL (Colombo Trinchieri, 2002). Upon binding to the CD52, Alemtuzumab starts a cytotoxic effect by antibody-dependent cell-mediated cytotoxicity mechanisms and complement fixation. Bevacizumab, a humanized monoclonal antibody, binds to essay information and sterically interferes with vascular endothelial growth factor preventing the activation of receptors. Bevacizumab is mostly used in the treatment of colon cancer and cleopatra and mark antony essay, renal cell carcinoma. And Development. It is known to increase the rate of response, interval of past task 1 response, and duration of information and development survival in a statistically relevant manner. Cetuximab is a chimeric monoclonal antibody targeting extracellular domains of epidermal growth factor receptors (EGFR).

It functions by inhibiting ligand binding, hence preventing EGFR activation. Mostly, it is indicated for the treatment of colorectal cancer. Other anti-EGFR monoclonal antibodies, still under development, include hR3, ABX-EGF and EMD 72000 (Gross, Walden, 2008). However, none of these agents are currently beyond phase one of the clinical trials, although they hold substantial promise for the future. Gemtuzumab ozogamicin is an anti-CD33 “immuno-conjugate” antibody that is chemically linked to a cytotoxic agent, calicheamicin. It is past papers mostly administered in information technology and development the treatment of should acute myeloid leukemia (AML). Essay Information. When combined with intensive chemotherapy, trials have reported high complete responses (85 per cent) in young adults. Minimal side effects are associated with Gemtuzumab therapy. Another chimeric monoclonal antibody, Rituximab, is specific for CD20 (widely expressed on B-cells). Researchers suggest that CD20 plays a role in calcium influx across plasma membranes, hence allowing for the activation of kennedy rice speech B cells.

However, the actual function of CD20 and the exact mode of information technology action of Rituximab is relatively unknown. Experiments with primates indicate that anti-CD20 treatment reduces peripheral B-cells by 98 percent, bone marrow B-cells and peripheral lymph node by up to 95 percent. Approved by essay ib tok the FDA in essay information technology 1998, Trastuzumab is a monoclonal antibody specific for the epidermal growth factor receptor 2 protein (HER2) (Yarden, 2001). Cleopatra And Mark Antony. It is clinically used in the treatment of breast cancer. Trastuzumab use is, however, restricted to patients whose tumours over-express HER-2. Over-expression or amplification of HER-2 is usually present in 25-30 percent of breast carcinomas (Yarden, 2001). It is associated with poor prognosis, aggressive tumour phenotype, reduced sensitivity to conventional chemotherapeutic agents, and non-responsiveness to hormonal therapy. Non-specific immunotherapies also assist in the fight against cancer. Most non-specific immunotherapies are, however, administered at essay and development, the same time or after other cancer treatments like radiation therapy or chemotherapy. Nevertheless, some non-specific immunotherapies are administered alone as treatments.

Common non-specific immunotherapies include interferons and interleukins. Interferons assist the immune system to ielts past papers fight cancer by slowing the growth of cancer cells. Interferons that are made in the lab called interferon alpha (Roferon- A [2a], Alferon N, Intron A [2b], are the essay information technology and development, most commonly used interferons in the treatment of cancer). Interferon alpha is mainly used in the treatment of non-Hodgkin lymphoma, kidney cancer, hairy cell leukemia, melanoma, kaposi’s sarcoma, and chronic myeloid leukemia (CML). Uwa Essay Writing. However, interferon treatment is not devoid of information and development side effects. These include an cleopatra and mark antony essay increased risk of infection, flu-like symptoms, thinning hair and rashes. Interleukins help the immune system in producing cells that help in technology and development fighting cancer. Interleukin-2, IL-2, or Aldesleukin (Proleukin), an uwa essay writing interleukin made in the laboratory, is used to treat skin cancer and kidney cancer (Trinchieri, 2003). Side effects of essay and development IL-2 include low blood pressure and weight gain, which can be treated with other medications. Vaccines assist the body to fight off cancer.

Cancer vaccines are of two types: treatment vaccines and prevention vaccines. Ielts Task 1. Treatment vaccines may stop the growth of essay cancer cells, prevent cancer from reoccurring, or destroy any remaining cancerous cells after administration of other modes of essay ib tok treatment. Essay Information Technology. Cancer vaccines are designed to be specific. This means that they are supposed to target cancerous cells and not healthy body cells. Should We Have. However, Sipuleucel-T (Provenge) is used in the treatment of metastatic prostate cancer and is the single treatment vaccine permitted in the United States today (Garcia-Lora, Algarra, Collado, Garrido, 2003). Essay Information Technology. Additional treatment vaccines are only available as clinical trials and are still under development. Prevention vaccines are administers to an individual with no cancer symptoms to and mark antony essay prevent the development of technology cancer (or other diseases). For example, Gardasil vaccine prevents a woman infection with Human Papilloma Virus (HPV), a virus that causes cervical cancer (Rosenberg, Yang, Restifo, 2004).

Gardasil is the first FDA-approved cancer vaccine. Cervarix vaccine is also an approved vaccine used in the prevention of cervical cancer in women and girls between 10 and 25 years (Rosenberg, Yang, Restifo, 2004). Today, several advances have been made in immunotherapy. Testing and development of second generation immunotherapies are already underway. Although antibodies targeted at disease causing antigens can be effective under certain circumstances, their efficacy is usually limited by other in many cases. For cancerous tumors, the microenvironment is immunosuppressive. It allows the tumors that exhibit unusual antigens to flourish and survive despite the immune response generated by the patient. Cytokines such as Interleukin-2 play a fundamental role in modulating the immune response. They are used in conjunction with antibodies to kennedy speech generate a more devastating immune response against cancer. Nevertheless, therapeutic administration of cytokines may cause systematic inflammation, causing serious side effects and toxicity. Some natural products have also shown promise in stimulating the immune system to fight off cancer.

Research shows that mushrooms like Agaricus blazei and Reishi are able to essay and development stimulate the immune system. Agaricus blazei is resources letter with no experience a potent stimulator of information natural killer cells and is rich in beta-glucans and we have homework, proteoglucans, which are effective stimulators of macrophages (Ribas, Butterfield, Glaspy, Economou, 2003). Information. Isolated and highly purified compounds from medicinal mushrooms, for example, Polysaccharide-K (isolated from Trametes versicolor ) and lentinan (isolated from Shiitake ), have been adopted into cleopatra and mark essay, the health care system of some countries, such as Japan (Ribas, Butterfield, Glaspy, Economou, 2003). In the essay information, 1980s, Japan approved the use of Polysaccharide-K on patients undergoing chemotherapy to stimulate the immune system. A mixture of a number of mycological extracts including Polysaccharide-K and lentinan is resources also sold commercially in Australia as MC-S. Does immunotherapy have any weaknesses or problems? The main likely problem with cancer immunotherapy is the need for time for information and development the body to respond. This is because in some patients, for example, those with Burkitt’s lymphoma, time is what the patient does not have (Copier, Whelan, Dalgleish, 2006). Cancer immunotherapy also does not work in writing cases of large tumors, and the tumor needs to be reduced in size (debulked) before immunotherapy has a chance to work. Immunotherapy is also immensely costly, and its price is not likely to drop any time in essay technology the near future. Monoclonal antibodies are also fabulously expensive.

Personalized vaccines do not come cheap either. For the patient, there are several basic questions that one should ask the doctor when he or she checks for immunotherapy. Why does the resources cover, doctor recommend immunotherapy? What are the essay information technology and development, goals of the treatment? Will immunotherapy be your only treatment? If not, what other treatments will form part of your treatment plan? How will you receive immunotherapy and essay ib tok, how often? What are the possible long term and short term side effects?

How will the treatment affect your daily life? Will you be able to perform your usual activities, work and exercises? What clinical trials of immunotherapies are open for you? In conclusion, many forms of cancer immunotherapy such as monoclonal antibodies save and prolong many lives making it, today, an established treatment modality. However, according to the American Cancer Society, immunotherapy is still a field that has not yet proven itself better than other cancer treatment types. Nevertheless, it is essay information a field that researchers believe hold a lot of promise for the future. Several other advances in the treatment of cancer will probably come from kennedy rice speech, this field. Times Magazine interestingly voted in two cancer researchers, Dr. Doug Schwartzentruber and Dr. Larry Kwak, for its list of world’s top100 most influential people in 2010.

Both researchers are in the forefront of cancer vaccine research. In spite of the high profile failures of immunotherapeutic treatments, in oncology, benefits for patients with a range of cancerous tumors have been relied. In addition, several cancer vaccines show great promise and are either under ongoing research or in the phase III of development. Although many hurdles still remain in the cure or prevention of cancer by using immunotherapy, there is at least some light at the end of the tunnel.
