in this study, frequency and location of frontogenesis related to heavy rainfall have been analyzed using environmental to circulation approach. based on the threshold of upper 99 percent, we selected 125 days of the super and overall heavy rainfall from irimo data base (included 1437 synoptic, climatic and rain gage stations from 21/3/1961 up to 31/12/2004). frontogenesis frequency and their l...
Stress-induced sensitization represents a process whereby prior exposure to severe stressors leaves animals or humans in a hyper-responsive state to further stressors. Indeed, this phenomenon is assumed to be the basis of certain stress-associated pathologies, including post-traumatic stress disorder and psychosis. One biological system particularly prone to sensitization is the hypothalamic-pi...
Large inspiratory pressures may impart stretch to airway smooth muscle and modify the response to deep inspiration (DI) in asthmatics. Respiratory system resistance (Rrs) was assessed in response to 5 inspiratory manoeuvres using the forced oscillation technique: (a) single unloaded DI; (b) single DI at 25 cmH(2)O; (c) single DI at 50% maximum inspiratory mouth pressure [MIP]; (d) 30 DIs at 50%...
Atmosphere and ocean general circulation model (AOGCM) experiments for the Intergovernmental Panel on Climate Change Fourth Assessment Report (AR4) are analyzed to better understand model variability and assess the importance of various forcing mechanisms on stratospheric trends during the 20th century. While models represent the climatology of the stratosphere reasonably well in comparison wit...
BACKGROUND Neonatal alloimmune thrombocytopenia is mostly due to the presence of maternal antibodies against the fetal platelet antigen HPA-1a on the platelet integrin GPIIb-IIIa. Accurate detection of anti-HPA-1a antibodies in the mother is, therefore, critical. Current diagnostic assays rely on the availability of pools of human platelets that vary according to donors and blood centers. There...
Previous work has implicated the forebrain glucocorticoid receptor (GR) in feedback regulation of the hypothalamic-pituitary-adrenocortical (HPA) axis. The present series of experiments used male mice with a targeted forebrain-specific GR knockout (in which forebrain includes the prefrontal cortex, hippocampus, and basolateral amygdala) to determine the role of forebrain GR in HPA axis regulati...
The hypothalamic-pituitary-adrenal (HPA) axis plays an important role in regulating and controlling immune responses. Dysfunction of the HPA axis has been implicated in the pathogenesis of rheumatoid arthritis (RA) and other rheumatic diseases. The impact of glucocorticoid (GC) therapy on HPA axis function also remains a matter of concern, particularly for longer treatment duration. Knowledge o...
Studies suggested that the married population has an increased risk of obesity and assimilation between spouses' body weight. We examined what factors may affect married spouses' resemblance in weight status and habitual physical activity (HPA) and the association of obesity/HPA with spouses' sociodemoeconomic characteristics and lifestyles. Medical Expenditure Panel Survey data of 11,403 adult...
BACKGROUND Heparanase, an endoglycosidase that cleaves heparan sulfate (HS), is involved in various biologic processes. Recently, an association between heparanase and glomerular injury was suggested. The present study examines the involvement of heparanase in the pathogenesis of Adriamycin-induced nephrotic syndrome (ADR-NS) in a mouse model. METHODS BALB/c wild-type (wt) mice and heparanase...
Fetal/neonatal alloimmune thrombocytopenia (F/NAIT) is the most frequent cause of haemorrhagic morbidity and mortality in otherwise healthy term infants and occurs in 1 in 1000 to 1 in 2000 pregnancies [1]. Maternal HPA-1a alloimmunization is responsible for the majority of NAIT [1], and only a few cases of NAIT caused by anti-HPA-3a have been published [2–4]. However, based on gene frequencies...
