Experimental results are strongly suggesting that PCSK9 and FXR could occur in the physiopathology of human joined dyslipidemia. But no data in the literature can validate the potential role of these two genes in the lipidic and glucidic metabolism control in physiopathological situations. This protocol is based on the hypothesis that the expression levels of PCSK 9 and FXR are modified for some patients suffering from insulin resistance and dyslipidemia.
The Environmental Protection Agency has recognized that organophosphorus pesticides require close regulation and continued monitoring for human health effects and some (e.g chlorpyrifos) have been phased-out from the consumer market due to the special risk that it posed for children. There is growing evidence in support of the association between pesticide exposure and childhood leukemia. Studies of pesticides and their association with childhood cancer have been limited by stu...
The project aims to improve the understanding of a significant group of rare diseases both from a genetic/diagnostic and clinical/experimental point of view and aims to develop one or more diagnostic protocols. The study will be conducted through the application of complementary experimental strategies, ranging from the clinical, genetic and molecular characterization of the pathology to the search for rare variants and the development of cellular disease models.
Experimental human malaria infections are generally accepted to be a powerful tool for evaluation of potential malaria vaccine and drug efficacies. Until now, experimental infections have been performed exclusively using infectious mosquitoes. Recently, Sanaria has been able to overcome the technical issues associated with the production of aseptic, purified, cryopreserved Plasmodium falciparum (Pf) sporozoites (PfSPZ). Performing experimental human malaria infections with asep...
1. Purpose: The goal of this study is to identify and characterize the genetic loci causing idiopathic talipes equinovarus (clubfoot). 2. Hypothesis: The hypothesis is that a few genes account for a substantial fraction of ITEV and that these genes can be identified in defined populations. Towards this goal, in preliminary studies, Dr. Hecht's group has identified two genes, NAT2 and CASP10, which demonstrate evidence for linkage and association to IT...
Schizophrenia has long been known to be an illness with significant evidence for a genetic predisposition. The purpose of this study is to determine the genetic abnormalities that cause childhood and adult onset schizophrenia.
The current study is part of a large multi-investigator grant to look at the pharmacogenetics of a number of membrane transporters. We will study individuals with particular genotypes of the human organic cation transporter, hOCT2, to test the hypothesis that genetic variation in hOCT2 is associated with variation in the renal clearance of the antidiabetic agent, metformin.
The goal of this study is to design a means of providing research families, from diverse geographical locations, the chance to receive genetic testing after having been educated by video, and meetings or telephone conversations with a genetic counselor/study professional.
This is phase I, double blind, placebo-controlled safety and infectivity study of experimental human Norovirus genogroup GII.4 administered to healthy adults 18-49 years of age. Subjects susceptible to the human norovirus GII.4 challenge strain. The challenge study will be conducted in 2-3 cohorts of approximately 20 subjects each.Subjects will remain in the inpatient facility for at least four days following challenge and assessed daily for clinical and virologic evidence of n...
The hypothesis to be tested: After the construction of a database of anthropometric measurements, the system would extract important features of a given facial surface and be able to match it with existing morphometric figures. A given combination of normal and abnormal measurements will open a "probable diagnosis" and a list of "differential diagnosis" that will be expressed as percent of matching in a descendent order to the examiner.
Like genetic mutations, DNA methylation anomalies or epimutations can disrupt gene expression and lead to human diseases. However, unlike genetic mutations, epimutations can in theory be reverted through developmental epigenetic re-programing, which should limit their transmission across generations. Following the request for a parental project of a patient diagnosed with Silver-Russell syndrome (SRS), and the availability of both somatic and spermatozoa DNA from the pro...
This study will explore scientists opinions and practices regarding the use of population descriptors (e.g., race, ethnicity, ancestry, geography and nationality) to describe a research study population. It will collect genetic researchers opinions, understandings and experiences studying human genetics and genetic variation. Scientists who are a principal investigator or co-principal investigator n a human genetic or genomic study of a common disease with at least preli...
In 1976 an accidental explosion in a chemical plant 16 miles north of Milan resulted in contamination of the local population with 2, 3, 7, 8-terachlorodibenzo-para-dioxin (TCDD). There is evidence that TCDD and related phenoxy herbicides act as teratogens, tumor promoters, and carcinogens in experimental animals. In human, TCDD causes chloracne in those exposed. Associations with various cancers have been reported, but the precise role in human toxicity, immune and reproduct...
In mammals, uterine environment is at low oxygen concentration (2-8% O2). Thus, human embryo culture under low O2 tension (5%) is now recommended by European Society of Human Reproduction and Embryology (ESHRE) revised guidelines for good practices in in vitro fertilization (IVF) labs. Indeed, hypoxia seems to improve embryo quality at cleavage and blastocyst stages, presumably by reducing damages of oxidative stress (OS). Nevertheless, recent meta-analyses concluded only with ...
This study will assess and characterize the variability observed in the response to darunavir therapy, an antiretroviral medication used against the Human Immunodeficiency Virus (HIV). More specifically, it aims to quantify variations in the drug's blood concentrations and determine the sources of such variability, both genetic and non-genetic. In light of this information, current dosage guidelines will then be reviewed.
The proposed study will address a critical knowledge gap: there are no evidence-based smartphone apps for reducing young adult drinking. The purpose of the study is to test alcohol-related smartphone applications designed to provide assistance during actual drinking situations to help young adults reduce their drinking. It is the researchers hypothesis that participants will self-administer less alcohol when using the experimental app with feedback.
Plasmodium falciparum isolates display a wide genetic diversity with possibly different properties to induce immune responses. These properties could directly influence the ability to induce protective efficacy. Since 1998 an experimental human malaria infection model at the Radboud University Nijmegen Medical Center (RUNMC) has been very successful in answering questions with regards to immunological mechanisms of human Pf infection. To date only the NF54 strain of Pf has been...
The goal of this collaborative research is to study human genomes in children with suspected congenital disease, multiple-congenital anomalies and/or multi-organ disease of unknown etiology by understanding the potential value of Whole Genome Sequencing (WGS) in establishing genetic diagnosis. The study will examine diagnosis rates, changes in clinical care as a result of a genetic diagnosis, health economics including potential cost-effectiveness of WGS and patient and provide...

This protocol is for a number of in vitro studies using human surgical biopsies and evaluating the pharmacology and genetics of human nociceptors ("pain detecting") neurons
The societal impact of heavy alcohol consumption and chronic pain is substantial and warrants the existing research investment into their etiology and treatment. Moreover, evidence of significant co-occurrence between these conditions offers an opportunity to examine mechanisms in the alcohol-pain connection that may inform the development of novel treatments. Consistent with NIH PA-15-026 (Mechanistic Studies of Pain and Alcohol Dependence), the goal of the proposed study is t...
Violence against women is a well understood devastating global pandemic, and human right violation. One in three women experienced intimate partner violence worldwide. In Ethiopia, the level of domestic violence against women is one of the highest in the world. However, Ethiopia is signatory for various conventions and incorporate into the constitution and other legal frameworks. Nevertheless, effective implementation of the existing policy documents, and engaging different sta...
About 10% of the calculable loss of health and quality of life in industrial countries can be attributed to excessive alcohol consumption. Behavioural pharmacological, genetic and clinical studies on alcohol dependence suggest a multifactorial model for the development of the disease, which ascribes an important role in the development of the disease to genetic variance, educational style and continued substance use. Animal and human experimental studies suggest that continued ...
This study aims to test the hypothesis that gene transcriptional changes occur within 24 hours of virus exposure in the blood and nasal mucosa, and to identify early biomarker signatures that are predictive of higher viral shedding at the peak of disease
This study will test the hypothesis that leptin contributes to the regulation of the dynamics of human endocrine function.
