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.
