Psychostimulants such as methamphetamine (MA) induce significant alterations in the function of the hypothalamic-pituitary-adrenal (HPA) axis. These changes in HPA axis function are associated with altered stress-related behaviors and might contribute to addictive processes such as relapse. In this mini-review we discuss acute and chronic effects of MA (adult and developmental exposure) on the ...

Dysregulation of hypothalamic-pituitary-adrenal axis (HPA) is seen in numerous mental disorders. Data of HPA axis disturbance in panic disorder are inconsistent. In panic disorder HPA axis hyperactivity has been observed with elevated cortisol levels. However, hypocortisolism has also been noted. Salivary cortisol as a biomarker of HPA-axis activity has received special attention. The aim of th...

Maternal alloantibodies against the human platelet Ag (HPA)-1a allotype of the platelet beta(3) integrin GpIIb/IIIa can cause severe fetal or neonatal hemorrhage. Almost all anti-HPA-1a-immune mothers are homozygous for HPA-1b and carry HLA-DR52a (DRB3*0101). The single Pro(33) -->Leu substitution (HPA-1b-->HPA-1a) was previously predicted to create a binding motif for HLA-DR52a that can lead t...

Results 342 of the patients were male and 42 were female. Mean age was 21.9±0.5 years old. Month (p=0.563), season (p=0.264) and weather (p=0.327) were not associated with the occurrence rate of SPM. Mean temperatures, mean humidity, mean wind velocities of SPM occurrence day and non-occurrence day were 12.4±10.5°C : 12.8±10.5° C (p=0.504), 61.8±15.5% : 60.9±15.0% (p=0.372), 2.6±1.0m/s : 2.6±2....

Alterations in hypothalamic-pituitary-adrenal (HPA)-axis activity and fatty acid (FA)-metabolism have been observed in (recurrent) major depressive disorder (MDD). Through the pathophysiological roles of FAs in the brain and cardiovascular system, a hypothesized relationship between HPA-axis activity and FA-metabolism could form a possible missing link accounting for the association of HPA-axis...

Hypothalamic-pituitary-adrenal (HPA) axis hormones and their receptors expressed in the skin are known to function locally, but how these hormones affect the maintenance of skin homeostasis or the pathogenesis of skin diseases is not fully understood. We comprehensively reviewed the distribution and function of the central and peripheral HPA axis in various stress-related skin diseases. Previou...

Plants are continually exposed to pathogen attack but usually remain healthy because they can activate defences upon perception of microbes. However, pathogens have evolved to overcome plant immunity by delivering effectors into the plant cell to attenuate defence, resulting in disease. Recent studies suggest that some effectors may manipulate host transcription, but the specific mechanisms by ...

BACKGROUND Distorted activity of the hypothalamic-pituitary-adrenocortical (HPA) system is one of the most robustly documented biological abnormalities in major depression. Lithium is central to the treatment of affective disorders, but little is known about its effects on the HPA system of depressed subjects. OBJECTIVE To assess the effects of lithium monotherapy on the HPA system of patient...

A novel picolinate-iron(III) compound, Fe(C6H4NO2)2(OH) (1), was synthesized from an aqueous solution of a picolinate-iron(II) complex. Compound 1 was obtained by a thermal treatment of the picolinate-iron complex aqueous solution, whose pH was adjusted to 3­7, containing more than twice molar picolinic acid (Hpa) to Fe at 353K for 72 h. When the iron aqueous solution in the presence of more th...
