The way COVID-19 transforms our sexual lives.

During the early stages of the outbreak, insufficient attention was paid to the impact on sexual function, which is logical in the face of potentially harmful and fatal infections. It is well documented that any close contact (6 feet or 2 m) with an infected person can result in exposure to SARS-CoV-2 so while coronavirus disease: (COVID-19) may not be "sexually transmitted" (through semen or vaginal fluids) the risks of proximal exposure are great-whether the activity is engaged in is sexual or not. For the last 3-4 months, scientific studies have shown that a mild or severe coronavirus infection can lead to sexual complications and prolonged libido problems as well as erectile dysfunction.

[Liver X receptors define the immune response during general adaptation syndrome (GAS)].

The impact of stressful conditions on immunity seems mixed and at times counterbalanced. Such inconsistencies can often be attributed to the fact that the notion of stress has a very wide meaning and covers a large number of different situations. Research on liver X receptors using both natural and synthetic ligands may help to solve this conflict.

A simple approach to studying cerebral blood flow during psychological stress.

The purpose of this work was to determine, in the Wistar male rats, the role of the stress system in the control of cerebral hemodynamics induced by emotional stress (air jet). Blood flow rates in the internal carotid arteries have been obtained using chronically implanted Doppler probes. In this investigation, air-jet stress provokes a rapid and substantial elevation of blood pressure combined with hyperemia and vasodilation.
