In a framework of search for early predictors of depression in patients with ischemic heart disease (IHD) we studied effect of molecular- genetic factors (polymorphism of brain-derived neirotrophic factor - BDNF), personality traits (anxiety, neuroticism), IHD severity, and psychosocial stressors on manifestations of depression in men with verified diagnosis of IHD. Severity of depression was assessed by Hamilton Depression Rating Scale 21-Item (HAMD 21), anxiety and neuroticism were evaluated by the Spielberger State-Trait Anxiety Inventory and "Big Five" questionnaire, respectively. It was shown that personal anxiety and ValVal genotype of BDNF gene appeared to be predictors of moderate and severe depression.

Blue Light-Induced, Dosed Protein Expression of Active BDNF in Human Cells Using the Optogenetic CRY2/CIB System.

The use of optogenetic tools offers an excellent method for spatially and temporally regulated gene and protein expression in cell therapeutic approaches. This could be useful as a concomitant therapeutic measure, especially in small body compartments such as the inner ear, for example, during cochlea implantation, to enhance neuronal cell survival and function. Here, we used the blue light activatable CRY2/CIB system to induce transcription of brain-derived neurotrophic factor (BDNF) in human cells.

Cannabidiol (CBD), a non-psychotropic compound derived from Cannabis sativa, is known for its potential therapeutic effects on central nervous system (CNS) disorders. This study investigates the effects of chronic CBD administration on depressive and cognitive alterations induced by social isolation in male C57BL/6 mice. The experimental design involved adult mice subjected to either group housing or 12 weeks of social isolation.

Dental caries is one of the most common health issues worldwide arising from the complex interactions of bacteria. In response to harmful stimuli, desirable outcome for the tooth is the formation of tertiary dentin, a protective reparative process that generates new hard tissue. This reparative dentinogenesis is associated with significant inflammation, which triggers the recruitment and differentiation of dental pulp stem cells (DPSCs).

The cornea is densely innervated to maintain the integrity of the ocular surface, facilitating functions such as sensation and tear production. Following damage, alterations in the corneal microenvironment can profoundly affect its innervation, potentially impairing healing and sensory perception. One protein frequently upregulated at the ocular surface following tissue damage is galectin-3, but its contribution to corneal nerve regeneration remains unclear.

Aims: Hyperammonaemia (HA) is a metabolic disorder characterized by increased ammonia levels in the blood and is associated with severe neurological impairments. Some previous findings have shown the involvement of the nitric oxide pathway in HA-induced neurological impairments. The current study explored the impact of tadalafil on neurological impairments induced by HA in a zebrafish larval model due to its reported indirect interactions with the nitric oxide pathway.
