The purpose of this study is to find out the roles of two specific gene families (the chitinase gene family and the TGFB family). We hypothesize that chitinases and TGFb pathway genes will be differentially expressed in the airways of non-asthmatic subjects and subjects with asthma. We further hypothesize that genetic variants in CHIT1, AMCase, and TGFb pathway genes that show associations with asthma and related phenotypes will change the expression and/or function of the prot...
This study uses a meal-challenge protocol to assess if patients with anorexia nervosa show a differential meal-induced metabolism and response compared to healthy controls, and determines how genetic variation influence this difference.
One of the goals of the Kansas City Diabetes Consortium is to identify and characterize genes and their products that are associated with T1DM. Characterization of such genes and their products can aid in developing new tools for risk assessment, development of new prevention strategies and monitoring progression of disease. Study design: Descriptive, basic science pilot study. The results of this pilot study will be used to help design a much larger study to address the imp...
It is generally understood that smoking during pregnancy has deleterious effects on the developing fetus, although research on smoking during pregnancy has been limited in focus, with most studies focused on birth weight of newborns and children's behavioral disturbances. However, little is known about the neurobiological underpinnings of nicotine-related developmental deficits and even less is known about genetic and environmental factors that may exacerbate the risk for such ...
This study is being done to learn more about how changes in certain genes may be linked to cancer. Some people with cancer got their disease because they inherited an abnormal (mutated) gene. The researchers of this study want to better understand the risks that are linked to genetic changes in these less well-studied genes. By understanding these risks, we believe that doctors will be able to give better advice to families with mutations in these genes.
To evaluate the difference in the prevalence of the main FSHR polymorphism (ASN680Ser), as well as other, less studied, gonadotropin polymorphisms between ovarian response groups, following ovarian stimulation
IGHN2 is an international, multicenter, double blind, randomized controlled trial aimed at assessing the efficacy on organ dysfunctions of Intravenous Immunoglobulins (IVIG) treatment in the acute phase of streptococcal or staphylococcal toxic shock syndrome in children.
The purpose of this research study is to determine whether analysis of genes in sputum is a useful noninvasive technique for measuring response to drugs in patients with COPD. We propose to use polymerase chain reaction to evaluate gene expression in induced sputum from adult current smokers with moderate COPD, adult former smokers with moderate COPD. This study is designed to determine whether changes in expression of previously-identified inflammatory markers in induced sput...
The purpose of this pilot study is to determine if patients randomized to a hospital sleep environment intervention would have improved sleep quality and reduced fatigue as compared to the patients not receiving the intervention (standard care).
The investigators propose to test for non-BRCA1/2 mutations in new and existing families with hereditary ovarian cancer in order to better define penetrance and associated malignancies of rare ovarian cancer susceptibility genes. The hypothesis is at least one third of hereditary ovarian carcinoma families wildtype for BRCA1/2 can be solved using an updated version of BROCA (BROCA-HR) that targets 47 genes, including all known ovarian cancer genes and additional candidate genes...
RATIONALE: Identification of genes that may be associated with developing certain types of cancer may someday provide important information about a person's risk of getting cancer. PURPOSE: This clinical trial is studying to see if certain genes may be associated with cancer in patients with cancer of the breast, prostate, lung, or colon and siblings of these patients.
This study is being conducted to compare the relationship of patient response to treatment to changes in tumor environment.
The purpose of this study is to help us learn more about the roles of genes in cancers. Genes are short pieces of DNA which determine the inherited characteristics that distinguish one individual from another. This study will look at how some genes might raise or lower the chance some people may develop cancer. The sample collection will help generate the materials needed for this study.
Congenital heart disease is one of the most common malformations in newborns. About 1% of newborns have cardiac malformations. Many need open heart surgery, which contributes substantially to pediatric mortality and morbidity. Recent advances in genetics suggest that many congenital heart defects are caused by mutation of genes. So far, half a dozen genes are found to be associated with congenital heart diseases, such as TBX5, NKX2.5, and GATA4, to name a few. In the near ...
The purpose of this study is to identify genes that affect susceptibility to obsessive-compulsive disorder (OCD). By identifying genes that increase or decrease the risk of OCD, researchers can better understand how the condition develops and ultimately improve treatment for people with OCD. OCD is a severe, familial condition that affects approximately 2% of the population. The way OCD is inherited is not clearly understood, but researchers believe it is complex and inv...
The goal of this study is to evaluate the effects of varenicline versus nicotine replacement versus placebo on personal smoking environment cue (PSE) reactivity. The results of this study will inform whether first-line pharmacotherapies for nicotine dependence (e.g. nicotine patch, varenicline) alter reactivity to environment cues. The investigators propose to identify 120 regular cigarette smokers who will complete 10 visits (1 screening visit, 1 training visit, 1 camera turn-...
The goal of this study is to determine the genetic basis of polycystic ovary syndrome (PCOS). We will first look for genes in the Icelandic population, where large family trees are known and it is easier to search for genes. We will then determine whether these same genes are important in U.S. PCOS patients.
This is a study designed to identify genetic polymorphisms (also called allelic variants or genetic markers) that are associated with response to clozapine. This information will be used to enhance the understanding of clozapine response and side effects. DNA from patients will be examined for significant associations between allelic variants in candidate genes in relation to clozapine effects on positive and negative symptoms, global response, quality of life, relapse rates ...
Each year, 17000 cases of severe hematological diseases are diagnosed in France, with more than 6,000 of these requiring hospitalization in a protective, sterile environment. New methods, such as touch massage, have emerged in response to anxiety symptoms observed in patients in such sterile and isolated surroundings. We hypothesize that during the period of isolation, touch massage becomes a nursing care which can help the patient.

The present study's goal is to identify a genetic basis for variations in responsiveness to plant sterol use, and elucidate which components of control of cholesterol metabolism associate with the genetic factors identified. The long term target is to contribute to a growing database that will be used in conjunction with rapid genotyping assays to allow future practitioners to determine if plant sterol intervention will be an effective lipid-lowering therapy in at-risk patients...
The purpose of this study is to explore how knowing genes that individuals inherit from their parents can make warfarin dosing more safe and effective. This study is being done to determine whether providing doctors with data on the genes their patients inherited and warfarin dosing recommendations based on those genes affects the costs and outcomes of care and after hospitalization for patients from different ethnic/racial backgrounds, and how physicians use this information ...
The goal of this clinical research study is to learn if the "protected environment" (PE) can help to prevent infections in patients aged 60 and above who are receiving what is considered low-intensity treatment for newly-diagnosed AML or high-risk MDS.
This is a dose-escalation study to determine the maximum tolerated dose and toxic effects of clofarabine in patients with chronic lymphocytic leukemia and other acute leukemias. Clofarabine is a synthesized hybrid nucleoside analog, which is believed to possess the better qualities of fludarabine and chlorodeoxyadenosine, the 2 most active agents against lymphoproliferative disorders. Thus, it is hoped that this drug will be more active and less toxic than similar drugs.
The purpose of the study is to investigate and compare the cell responses to influenza vaccination in monozygotic (identical) and dizygotic (fraternal) twins to determine the roles of genetics and environment in the response to flu vaccination.
