This suggests that a genetic factor is involved. MZ twins share 100% of their genes; DZ twins share 50% of their genes. If genes are a factor we would expect more identical twins to share the disorder than non-identical. Rosenthal took a case study which had a set of female quadruplets. They all developed schizophrenia although the onset and symptoms were very different.
In order to draw a conclusion about the effectiveness of preventive surgeries, I would need to see a chart of how many people the surgery was a success for and for how many people it had no effect. Based on the average ages, both of these mutations affect older woman. The average age at diagnosis for the BRCA1 mutation is 43.9, while the average age for BRCA2 is 46.2. The women that these mutations effect most likely have already had kids and may have passed the cancer down to their
However, some of these later groups were born by fathers who are older that 60 years. This indicates a possible increase in epigenetic damage in the spermatogenesis of older men than the young and the possibility of other etiological theories. The twin and adoption studies are main evidence that supports a genetic etiology of Schizophrenia. Currently, there is no model of genetic transmission of Schizophrenia. However, further evidence for genetic etiology of Schizophrenia has arisen with the linkages and
The biological explanations for depression centre on the mood disorder being biologically caused. Genetic factors suggest that you are born with a biological weakness which makes you unable to resist stressors, which consequently leads to depression. This is known as the diathesis stress model. The main piece of research that supports this comes from the Maudsley Hospital twin register, where concordance rates of 46% were found in MZ twins and 20% in DZ twins. This suggest that depression must be passed on through genes if there is a high concordance rate between twins which share the same genetic makeup both having depression.
A 2003 analysis by the CDC found that “the prevalence of diabetes, either diagnosed or undiagnosed, and of impaired fasting glucose did not appear to increase substantially during the 1990s,” despite the sharp rise in obesity. “Undiagnosed diabetes” refers to people who have a single positive test for high blood sugar in the CDC surveys. (Two or more positive results are required for a diagnosis of diabetes.) Gregg’s paper in April reiterates the oft-repeated “fact” that for every five adults diagnosed with diabetes, there are three more diabetics who are undiagnosed. “Suspected diabetes” would be a better term, however, because the single test used by the CDC may be wildly unreliable.
It was found that having an identical twin with schizophrenia gave you a 48% chance of developing the condition. This reduced to 17% in non-identical twins. They concluded that schizophrenia has a strong genetic basis, however, if it was entirely down to genetics, we would expect this figure to be 100% for identical twins. The meta analysis was carried out on field experiments, so has high ecological validity. The fact that both twins wouldn’t always develop schizophrenia means that another factor must be involved, for example family environment.
Johnny Martin Paper 4 English 5A 9/12/2011 K. Crews Summary: What We Miss About the 1950’s Stephanie Coontz's essay “What we really miss about the 1950's” is an essay that talks about a poll taken in 1996 by the Knight-Ridder news agency. That poll showed that more Americans preferred the 1950's as the best decade for children to grow up in. Coontz doesn't believe that the 50’s are a decade for people to remember about, except for financial reasons and better communication within families. Coontz doesn't believe in it as the best decade because of the votes, the 50's only won by nine percent, and especially not by African Americans. She doesn't believe that the 50's should be taken 'literally' because from the 50's there were changes in values that caused racism and sexism discrimination against women.
Because of the way the disease is inherited, it is much more likely for a male to obtain the disease because they have only one X chromosome, whereas females have two so it would be more difficult for them to receive it on both of their chromosomes. According to the Muscular Dystrophy Campaign, more than half of the cases of Duchenne disorder are inherited from the mother. This is because it is likely for a mother to be a carrier by the gene, but they are not typically affected by the disorder. Looking at it that way, the son of a carrier has a fifty-fifty chance of being affected while the daughter has a fifty-fifty chance of being a carrier alone. According to the same source, quite a small amount of female carriers experience a very small degree of muscle weakness
Although this number is pretty low, US is still ranked highest among countries based on infant mortality rates within the OECD countries. If the US cannot take care of our babies then how can they take care of us? The US is currently deciding on whether to pass the healthcare reform bill, which seeks to expand health care coverage to the approximately 40 million Americans who are currently uninsured by lowering the cost of health care and making the system more efficient (OpenCongress). But sometimes austere actions need to be taken otherewise the purpose gets defeated and victory accompanies the opposition. And in this case Canada has won the race against the
From the research, I think it is also fair to say that Texas has an immigration issue as 46 percent of their homeless children are Hispanic, a larger number than any other state in America. The next comparison I will make is between Indiana and neighboring Ohio. Ohio is ranked 10 spots better than Indiana while much of Ohio’s numbers paint a darker picture than those of Indiana. Again, I believe that because Ohio is in the early stages of planning to reduce child and family homelessness their “grade” is better than Indiana who, like Texas, has no plan in
