Clinical Features in Russian Patients with COVID-Associated Parosmia/Phanthosmia.

Background: Olfactory dysfunction is a typical symptom of COVID-19 infection. While COVID-associated anosmia is well-described, knowledge of parosmia (olfactory distortions) and phanthosmia (olfactory hallucinations) is relatively lacking. We undertook a clinical study of the parosmia/phanthosmia phenotype, aiming to support improved prediction and management of these symptoms.

[Care of young, aggressiveness, and secretion of testosterone in male rodents: a correlation analysis ].

To test the current hypotheses on the relationship between the mating system, reproductive strategy, aggression, and secretion of testosterone, a comparative study of interactions in pair encounters, the level of parental care, and the gonadal testosterone level in males was performed in six rodent species (Clethrionomys rutilus, Meriones meridianus, Microtus arvalis, Lagurus lagurus, Lasiopodomys Mandarinus, and Meriones unguiculatus) with different types of spatial-and-ethological population structures (SEPSs). It is shown that this. dependence is absent in species with promiscuous mating and dominance hierarchy among males (C.

[The effect of the ACTH(4-10) fragment on certain forms of adaptive behavior in mice of various genetic groups].

CBA/Lac/Sto mice, C57/BL/6J mice and random bred mice with robertsonian translocation of chromosomes 8 and 17 (T1IEM mice) were compared under normal conditions and after ACTH4-10 injections. The rate of food procuring learning in U-shaped maze and in radial 5-arm maze was studied, and the ability of mice to extrapolate the direction of stimulus movement. Peptide i.

[Effect of amizil and the ACTH4-10 fragment on the ability of mice to extrapolate the direction of movement].

Mice possessing the ability to extrapolate the direction of movement (100% of correct choices) were injected i.p. with different doses of m-cholinolytic amizil 2 hours before experiment.

[Effect of ACTH4-10 on the behavior of mice].

The effect of 40 mcg/kg i. p. injections of ACTH4-10 were investigated in C57BL/6J mice.
