post-traumatic stress disorder (ptsd) is a syndrome causing from a severe traumatic happening that leads to threatened death or injury. ptsd is associated with changes in limbic, hippocampal, and prefrontal cortical region function due to changes in synaptogenesis, dendritic modifying, and neurogenesis. changes in neuron in ptsd patients result from pathophysiological disturbances in inflammato...

Neuregulins (NRGs) are expressed in spinal cord motor neurons and accumulate at the neuromuscular junction where they may increase the synthesis of postsynaptic acetylcholine receptors and voltage-gated sodium channels. We demonstrate here that NRG expression is selectively increased in rat ventral spinal cord neurons at approximately the time that nerve-muscle synapses first form. A rapid incr...

A hexasaccharide representing a major sequence in porcine mucosal heparin has been enzymatically prepared from heparin. Its structure was determined by an integrated approach using chemical, enzymatic, and spectroscopic methods. Two-dimensional 1H homonuclear COSY, C-H correlation NMR, and selective irradiation were used to assign many of the NMR resonances. In addition, new techniques includin...

Generation and inhibition of activated factor IXa was studied in factor XIa-activated plasma containing 4 mmol/L free calcium ions and 20 mumol/L phospholipid (25 mol% phosphatidylserine/75 mol% phosphatidylcholine). Interference of other (activated) clotting factors with the factor IXa activity measurements could be avoided by using a highly specific and sensitive bioassay. Factor IXa generati...
