Fetal/neonatal alloimmune thrombocytopenia (FNAIT) is often caused by maternal alloantibodies against the human platelet antigen (HPA)-1a, which opsonizes fetal platelets (PLTs). Subsequent PLT destruction is mediated via the Fc part of the alloantibodies. The monoclonal antibody (mAb) SZ21 binds to the HPA-1a epitope and inhibits the binding of maternal alloantibodies. However, it also promote...
altered glycosylation of proteins in cancer cells is one of the main processes responsible for anaplasia, invasion and metastatic potential of neoplastic cells. lectins are nonimmunogenetic compounds which specifically detect certain terminal sugars of glycoconjugates. the aim of the present study was to identify the n-acetylgalactosamine (galnac) containing glycoconjugates in cancer cells in a...
The meteorological conditions during the period of spring transition over the Middle East and the Persian Gulf and adjacent land area is investigated. Monthly and seasonal variations of large-scale atmospheric patterns and wind aloft features at different levels were drawn from data collected from the National Centers for Environmental Prediction and National Center for Atmospheric Researches. ...
The downy mildew pathogen Hyaloperonospora arabidopsidis (Hpa) is a filamentous oomycete that invades plant cells via sophisticated but poorly understood structures called haustoria. Haustoria are separated from the host cell cytoplasm and surrounded by an extrahaustorial membrane (EHM) of unknown origin. In some interactions, including Hpa-Arabidopsis, haustoria are progressively encased by ho...
Organisms react to environmental challenges by activating a coordinated set of brain-body responses known as the stress response. These physiological and behavioral countermeasures are, in large part, regulated by the neuroendocrine hypothalamic-pituitary-adrenal (HPA) axis. Normal functioning of the HPA axis ensures that an organism responds appropriately to altered environmental demands, repr...
Detailed dynamics of the hypothalamic-pituitary-adrenal (HPA) axis is complex, depending on the individual metabolic load of an organism, its current status (healthy/ill, circadian phase (day/night), ultradian phase) and environmental impact. Therefore, it is difficult to compare the HPA axis activity between different individuals or draw unequivocal conclusions about the overall status of the...
The vertebrate hypothalamus–pituitary–adrenal (HPA; or interrenal) axis plays pivotal roles in animal development and in physiological and behavioral adaptation to environmental change. The HPA, or stress axis, is organized in a hierarchical manner, with feedback operating at several points along the axis. Recent findings suggest that the proteins, gene structures, and signaling pathways of the...
Little is known about the role of the basolateral amygdala (BLA) in regulating hypothalamic-pituitary-adrenal (HPA) activity, particularly chronic stress-induced HPA activity. In the current studies, we examined the effects of manipulations of the BLA on HPA responses to the eighth restraint, to novel restraint after repeated cold, or to acute novel restraint alone. Excitotoxic lesions of the B...
Birds breeding at high latitudes can be faced with extreme weather events throughout the breeding season. In response to environmental perturbations, vertebrates activate the hypothalamic-pituitary-adrenal (HPA) axis and synthesize corticosterone, which promotes changes in behavior and physiology to help the animal survive. The parental care hypothesis suggests that the HPA axis activity should...
