A short-term deprivation of rat pups from breastfeeding in the early postnatal period leads to MS at the age of 4-6 months. However, this neonatal MS model requires optimization and a detailed study into the metabolic and hormonal parameters of adult animals. The aim of the work was to study these parameters in adult male rats deprived of breast milk at the age of 19-21 days, which was achieved by treating lactating females with bromocriptine. Adult male rats showed an increased body weight and adipose tissue, impaired glucose tolerance, insulin resistance, and hyperleptinemia. These animals had reduced levels of testosterone, free thyroxine, and total triiodothyronine, with an increase in the thyroid-stimulating hormone. Thus, a short-term deprivation of breastfeeding in adult rats leads to the development of MS and endocrine dysregulations.

To simulate a convulsive syndrome, phenylcarbamate was administered intraperitoneally at a dose of 1 mg/kg. Valproic acid aminoester (43 mg/kg), caramiphene (50 mg/kg), and diferidine (2 mg/kg) were investigated as potential anticonvulsant drugs. Blood and brain tissue for the determination of acetylcholinesterase (AСhE) were taken at 10, 30, 60 minutes, 6 and 24 hours after administration of the xenobiotic. In case of poisoning with reversible inhibitors of AChE and accumulation of acetylcholine in the CNS synapses (due to inhibition of AChE activity), only the initial manifestations of convulsive activity are caused, and other mechanisms not associated with AChE inhibition are responsible for the processes of further maintenance and recurrence of seizures.

In type 2 diabetes mellitus (DM2), the impaired functions of the brain insulin system are associated with the weakened insulin transport through the blood-brain barrier due to insulin resistance. Insulin deficiency in the brain can be corrected by intranasal administration of insulin (II), whose effect may be enhanced by intranasal administration of C-peptide (ICP). In this work, we study the effect of treating hyperinsulinemic and normoinsulinemic DM2 rats with ICP (36 µg/rat/day), II (20 µg/rat/day) and ICP+II on metabolic and hormonal parameters. In normoinsulinemic DM2, ICP attenuated thyroid hormone deficiency and enhanced the restorative effects of II on glucose, insulin, and leptin sensitivity. In hyperinsulinemic DM2, ICP was ineffective, and its combination with II weakened the restorative effects of II. Thus, ICP and its combination with II are effective in restoring metabolic and hormonal parameters in normoinsulinemic, but not hyperinsulinemic, DM2.

This research was aimed at creating novel domestic medical preparations with a modified release of active peptide substances obtained from renewable sources of biological materials. These preparations can be used for the purposes of pharmacological correction of desynchronosis by the action of biologically active substances on the processes of lipid peroxidation and antioxidant protection of cells in order to increase the body's resistance to the negative effects of various stress factors. The conducted studies have confirmed the efficacy of modified-release peptide extracts when correcting the body's oxidative status in various types of desynchronosis.

Following a single administration of sodium thiopental in high doses (85 mg/kg intraperitoneally), the animals demonstrated the absence or weakening of reflexes at the levels of the spinal cord, medulla oblongata, bridge and midbrain and cerebral cortex over the period of one day. Other signs included a pronounced hypothermia, a decrease in the respiratory rate and a violation of its rhythm, a distinct tendency to bradycardia. On days 1-3 after the administration of sodium thiopental, a restoration of the respiratory rate, heart rate, body temperature, and the functional state of the central nervous system at various levels was observed, with the exception of the cerebral cortex. In the long term, following the administration of sodium thiopental for up to 21 days, a depression of the functional state of the central nervous system at the level of the cerebral cortex, violation of coordinated propulsive peristalsis of the small intestine and intestinal microbiocenosis were detected. Hence, in experimentally simulated barbiturate poisoning, not only is the suppression of the functions of the central nervous system observed, but also significant and prolonged restructuring of the functional state of the gastrointestinal tract.

In type 1 diabetes mellitus, the impaired testosterone synthesis in the testes leads to androgen deficiency. The long-term application of high gonadotropin doses for its correction decreases the sensitivity of luteinizing hormone/human chorionic gonadotropin (LH/hCG) receptors in Leydig cells to the endogenous gonadotropins. The aim of this work was to study the effect of a 3-day treatment of male Wistar rats with streptozotocin type 1 diabetes with the 5-amino-N-tert-butyl-2-(methylsulfanyl)-4-(3-(nicotinamido) phenyl)thieno[2,3-d]pyrimidine-6-carboxamide allosteric LH/hCG receptor agonist (TP03, 15 mg/kg/day) on steroidogenic effects of a relatively low-dose hCG (10 IU/rat, single dose, s.c.). Pretreatment of diabetic rats with TP03 enhanced the stimulatory effect of hCG on testosterone levels, slightly modifying its effects on the expression of steroidogenic proteins (Star, Cyp11a1, Cyp17a1) and LH/hCG receptor (Lhr) genes. Thus, in type 1 diabetes, TP03 increases the steroidogenic effect of low-dose hCG, at the same time as maintaining its effect on the gene expression of LH/hCG receptor and steroidogenesis enzymes in the testes.
在1型糖尿病中，睾丸激素合成受损导致雄激素缺乏。长期应用高剂量的促性腺激素进行校正会降低间质细胞中促黄体生成素/人绒毛膜促性腺激素(LH/hCG)受体对内源性促性腺激素的敏感性。本研究的目的是研究用5-氨基- n -叔丁基-2-(甲基磺胺基)-4-(3-(烟酰胺)苯基)噻吩[2,3-d]嘧啶-6-羧酰胺变构LH/hCG受体激动剂(TP03, 15 mg/kg/天)治疗链脲霉素1型糖尿病雄性Wistar大鼠3天对相对低剂量hCG (10 IU/大鼠，单剂量，s.c)的甾体致生作用。TP03对糖尿病大鼠的预处理增强了hCG对睾酮水平的刺激作用，轻微改变了其对类固醇蛋白(Star、Cyp11a1、Cyp17a1)和LH/hCG受体(Lhr)基因表达的影响。因此，在1型糖尿病中，TP03在维持其对睾丸LH/hCG受体基因表达和类固醇生成酶的影响的同时，增加了低剂量hCG的类固醇生成作用。

Human serum albumin (HSA) is a natural buffer for amyloid в peptide (Аβ), which is a key factor in the development of Alzheimer's disease (AD). An increase in HSA affinity to Аβ can be achieved via HSA saturation with low-molecular-weight ligands, such as serotonin or specific fatty acids. The conducted analysis of the genomic data of exomes (WES) associated with AD (ADSP database) revealed the presence of a single-nucleotide polymorphism of the HSA gene at the binding sites of ibuprofen, arachidonic and oleic acids. Research into the properties of the revealed genetic variants of HSA should be carried out to determine those variants that are susceptible to the modulatory action of HSA ligands, thus increasing its affinity to Aβ.

The effect of gamma-aminobutyric acid (GABA) on the gut microbiota was evaluated in experiments on 47 rats with metabolic stress (MS) induced by food deprivation. MS was found to be associated with changes in the qualitative and quantitative composition of the caecum microbiota, including the redistribution of opportunistic flora, the growth of pathogenic microorganisms, as well as a decreased number of lactobacilli and bifidobacteria. Daily administration of GABA at a dose of 70 mg/kg during MS led to a decrease in the number of pathogens, thus leading to the restoration of normal eubionts in the cecum.

The myostatin protein, belonging to the family of growth factors, represents a potential target for therapeutic effects in muscular system pathologies. However, this protein is characterized by other beneficial properties. Polymorphisms of the myostatin gene associated with the restriction of its functional activity are useful as genetic markers of meat productivity in farm animals. Blocking the action of myostatin in productive animals can be achieved by inducing the synthesis of specific autoantibodies using recombinant myostatin, possessing sufficient immunogenicity against myostatin as an antigen. A genetic construct was created and an E. coli producer strain with a high level of expression of recombinant myostatin was obtained.

The effect of ultrasound-induced stress on the gut microbiota composition of C57BL/6 mice was studied. Under the action of this type of stress, the gut microbiota composition shifts towards firmicutes at the phylum level. At the family level, an increase in Lachnospiraceae by 67.43%, Rikenellaceae by 39.29%, as well as a decrease in Bacteroidaceae by 64.75% and Prevotellaceae by 38.51%. is observed. The most prominent changes under the action of stress were revealed at the genus level: out of 28 identified genera, significant changes were recorded in 13.
