Morphological and histochemical investigations of the activity of succinate, malate, lactate, isocitrate, and glucoso-6-phosphate dehydrogenases, and NAD-diaphorase in the central, marginal, borderline and perifocal zones of ischemic brain infarctions were carried out. Deep changes in the activity of the enzymes listed, and peculiarities of this activity in various brain structures and tissues were revealed. A connection between the activity of the enzymes, the duration of the infarction, and the structural and biochemical peculiarities of the affected brain part is demonstrated. A suggestion is made on the pathogenesis of the ischemic infarctions and on the possibility of using histochemical data for the purposes of the pathoanatomic diagnosis.

Sorafenib (Sora) is a first-line treatment for patients with advanced hepatocellular carcinoma (HCC). It can significantly improve the survival rate of patients with advanced HCC, but it is prone to drug resistance during treatment, so the therapeutic effect is extremely limited. Here, we demonstrate that an elevated expression of protein kinase p38γ in hepatocellular carcinoma cells diminishes the tumor cells' sensitivity to Sora.

Background: Multiple sclerosis (MS) is a chronic autoimmune condition that damages the myelin sheath of neurons in the central nervous system, resulting in compromised nerve transmission and motor impairment. The astrocytopathy is considered one of the prominent etiological factor in the pathophysiology of demyelination in MS. The expression level of ceramide synthase-2 (CS-2) is yet to be established in the pathophysiology of astrocytopathy although the derailed ceramide biosynthetic pathways is well demonstrated in the pathophysiology of demyelination.

Synthetic insecticides have been widely used for the prevention and control of disease vectors and agricultural pests. However, frequent uses of insecticides have resulted in the development of insecticide resistance in these insect pests. The resistance adversely affects the efficacy of insecticides, and seriously reduces the lifespan of insecticides.

The tumor suppressor LKB1/STK11 plays important roles in regulating cellular metabolism and stress responses and its mutations are associated with various cancers. We recently identified a novel exon 1b within intron 1 of human LKB1/STK11, which generates an alternatively spliced, mitochondria-targeting LKB1 isoform important for regulating mitochondrial oxidative stress. Here we examined the formation of this novel exon 1b and uncovered its relatively late emergence during evolution.

Antibiotic-resistant strains of Staphylococcus aureus pose a significant threat in healthcare, demanding urgent therapeutic solutions. Combining bacteriophages with conventional antibiotics, an innovative approach termed phage-antibiotic synergy, presents a promising treatment avenue. However, to enable new treatment strategies, there is a pressing need for methods to assess their efficacy reliably and rapidly.
