OBJECTIVE The present research examined the effects of the social environment on the onset of specific health ailments. DESIGN Using data from the Health and Retirement Study, we examined participants' responses to social environment questions in 2006 as predictors of onset of different health conditions over the next four years. MAIN OUTCOME MEASURES Healthy participants (n = 7514) reporte...

The control of CD4 gene expression is essential for proper T lymphocyte development. Signals transmitted from the T-cell antigen receptor (TCR) during the thymic selection processes are believed to be linked to the regulation of CD4 gene expression during specific stages of T cell development. Thus, a study of the factors that control CD4 gene expression may lead to further insight into the mol...

background: women 35-39 years old have a 2–3 fold higher risk of pregnancy-related death than women in their twenties and the risk is even more dramatic for women 40 years and older. objective: the aim of this study was to investigate the association of maternal age with risk of adverse pregnancy and mother outcomes in our setting tehran iran. materials and methods: in this retrospective observ...

How does language relate to the non-linguistic world? If an agent is able to communicate linguistically and is also able to directly perceive and/or act on the world, how do perception, action, and language interact with and influence each other? Such questions are surely amongst the most important in Cognitive Science and Artificial Intelligence (AI). Language, after all, is a central aspect o...

An unresolved issue regards the role of p73 and p63, the two homologs of the p53 oncosuppressor gene, in normal cells and in tumor development. Specific target genes for each protein need to be identified and characterized in order to understand the specific role of each protein in tumor initiation and progression as well as in oncosuppression and development. We tested whether p63 is implicate...

Objective: To compare the reliability of ligase chain reaction (LCR) to polymerase chain reaction (PCR) in detecting Chlamydia trachomatis endocervical infections. Methods: We conducted a prospective study of 486 patients at risk for chlamydial infection of the endocervix. We obtained two endocervical specimens from each patient and used LCR and PCR to detect C. trachomatis. Discrepant results ...

Importance sampling lattice simulations are able to provide vital information about the nature of the temperature driven phase transition for 2 and 3 color Yang-Mills theories with and without matter fields (see [ 5, 6] for 3 colors). At zero temperature the SU(N) Yang-Mills theory is asymptotically free, and the physical spectrum of the theory consists of a tower of hadronic states referred to...
