A Mathematical Model for the Secretion of Human Corticotrophin Releasing Hormone and Its Relationship with Stress Variables

چکیده
In this paper, we analyze a dual characterization of life distributions that is based on entropy applied to the past lifetime. Various aspects of this measure of uncertainty are considered, including its connection with the residual entropy. Results on the past entropy is obtained by using the reversed hazard function of X, which is receiving increasing attention in reliability theory and survival analysis. The formula for the past entropy H(t) when X is exponentially distributed is obtained and this formula is utilized for our application part. The formulaH(t) for peripheral administration of CRH is obtained and found that the stress variables increased monotonically upward with

P146: Gamma Aminobutyric Acid (GABA) and its Alterations in Stress
Gamma aminobutyrate (GABA) is a non-protein amino acid that is thought to play an important role in the modulation of the central response to stress. Mechanisms by which GABA may facilitate these responses to stress are metabolic and/or mechanical disruptions. Environmental stresses increase GABA accumulation through cytosolic acidification, induce an acidic pH-dependent activation of glutamate...
متن کاملCorticotrophin-releasing hormone decreases synaptic transmission in rat sensorimotor cortex in vivo.
Corticotrophin-releasing hormone is a key regulator of the mammalian stress response. Although its actions on behavior are well documented, the actions of corticotrophin-releasing hormone in cortical neuronal systems are poorly understood. In the present experiments, adult male Sprague-Dawley rats were anesthetized and field excitatory post-synaptic potential recordings were made from sensorimo...

متن کاملLateral Hypothalamus Corticotropin Releasing Hormone Receptor-1 Inhibition Modulates Stress- Induced Anxiety Behavior
Stress is a reaction to unwanted events disturbing body homeostasis which influences its pathways and target areas. Stress affects the brain through the lateral hypothalamic area (LHA) orexinergic system that mediates the effect of corticotropin-releasing hormone (CRH) through CRH receptor type 1 (CRHr1). Therefore, this study explores the outcome of stress exposure on anxiety development and t...
متن کاملRole of thyrotrophin releasing hormone and corticotrophin releasing factor in stress related alterations of gastrointestinal motor function.
There is a growing body of experimental and clinical evidence to indicate that stress influences gastrointestinal motility. The most common pattern of gastrointestinal motor alterations induced by a variety of different stress factors is that of delayed gastric emptying and accelerated colonic transit. Central administration of corticotrophin releasing factor mimics both of these effects. This ...
