Natalizumab is a humanised monoclonal antibody targeting the lymphocyte adhesion molecule a4 integrin, with proven efficacy in multiple sclerosis (MS) and Crohn's disease (CD). The development of sarcoidosis with extrapulmonary involvement is reported in two patients with refractory CD who had received maintenance therapy with natalizumab. This complication has not been previously reported. It ...

BACKGROUND Parental support is a key influence on children's health behaviours; however, no previous investigation has simultaneously explored the influence of mothers' and fathers' social support on eating and physical activity in preschool-aged children. This study evaluated the singular and combined effects of maternal and paternal support for physical activity (PA) and fruit and vegetable c...

BACKGROUND Couples with unexplained recurrent miscarriage may have an alloimmune abnormality that prevents the mother from developing immune responses essential for the survival of the genetically foreign conceptus. Immunisation with paternal mononuclear cells is used as a treatment for such alloimmune-mediated pregnancy losses. However, the published results on this treatment are conflicting. ...

Over the last decade, there has been a significant increase in average paternal age when the first child is conceived, either due to increased life expectancy, widespread use of contraception, late marriages and other factors. While the effect of maternal ageing on fertilization and reproduction is well known and several studies have shown that women over 35 years have a higher risk of infertil...

background: various responses and different prognosis to specific treatment in different patients from one hand, and importance of ifn-γ producer cells on the other hand impressed us to study tc1. methods: the study was conducted in ghaem medical center and bu-ali research institute, mashhad university of medical sciences, iran from 2001 to 2002. lymphocytes of 36 patients were counted and cult...

Few patients with osteonecrosis that complicates human immunodeficiency virus (HIV) infection have been reported. We describe 5 patients whose symptoms of osteonecrosis developed with viral suppression and improvement in CD4 lymphocyte counts as a result of antiretroviral therapy. In addition, we review previously reported cases. The mean patient age was 35 years, and HIV was the sole risk fact...

Cell division is closely related to telomerase activity (hTERT mRNA). Lower expression of lymphocitic hTERT mRNA may easily cause cell aging, which is not beneficial to maintaining a durable lymphocyte division. To date, there is no study to investigate IFNα therapy on hTERT mRNA expression in PBMCs of patients with chronic hepatitis B (CHB). We quantitatively detected hTERT mRNA from study sub...

Evidence for paternal kin recognition and paternally biased behaviors is mixed among primates. We investigate whether infant handling behaviors exhibit paternal kin biases in wild white-faced capuchins monkeys (Cebus capucinus) by comparing interactions between infants and genetic sires, potential sires, siblings (full sibling, maternal, and paternal half-siblings) and unrelated handlers. We us...
