[Difficulties in lifetime diagnosis of Creutzfeldt-Jakob disease].

Creutzfeldt-Jakob disease (CJD) is a classic representative of the group of prion diseases and is characterized by progressive degeneration of the structures of the nervous system with a variety of neurological symptoms, steady progression and inevitable death. The disease is based on a change in the tertiary structure of the protein, which leads to disruption of the normal functioning of cells. Despite the fact that the etiology and pathogenesis of CJD are now well studied, intravital diagnosis of this serious disease remains difficult due to the peculiarities of the pathological process (unusually long incubation period, variety of clinical symptoms), the lack of pathognomonic markers that make it possible to make a diagnosis with a high degree of confidence, and also insufficient awareness of medical workers.

Adeno-Associated Viral Vectors in the Treatment of Epilepsy.

Epilepsy is a brain disorder characterized by a persistent predisposition to epileptic seizures. With various etiologies of epilepsy, a significant proportion of patients develop pharmacoresistance to antiepileptic drugs, which necessitates the search for new therapeutic methods, in particular, using gene therapy. This review discusses the use of adeno-associated viral (AAV) vectors in gene therapy for epilepsy, emphasizing their advantages, such as high efficiency of neuronal tissue transduction and low immunogenicity/cytotoxicity.

[PET/CT MOLECULAR CELL IMAGING OF ACUTE PYELONEPHRITIS IN THE DIAGNOSIS OF FEVER OF UNKNOWN ORIGIN].

In addition to tumor imaging, advanced high-tech PET/CT imaging is increasingly used to elucidate the underlying causes of fever of unknown origin caused by various inflammatory processes, including pyelonephritis. Two clinical cases of whole-body PET/CT with 18F-FDG glucose, which allowed to visualize the molecular and cellular features of acute pyelonephritis as the cause of fever of unknown origin, are presented in the article. The scientifically based mechanisms of this process and the reliability of the results are discussed.

The Influence of Metabolites of Microorganisms of the Genus Bacillus from Permafrost Rocks on T Lymphocyte Differentiation.

We studied the influence of metabolites of permafrost microorganisms obtained at different temperature incubation conditions on activity of differentiation of regulatory (Treg) and effector T lymphocytes. It was found that the effect of metabolites is largely regulated by their type that depends on the temperature of production ("cold" at 5°C, "medium temperature" at 22°C, and "warm" at 37°C). The studied metabolites influenced the differentiation of Tregs (CD4CD25CD127) and the expression of markers of early (CD69), middle (CD25), and late (HLA DR) activation of CD4 and CD8 T lymphocytes.

[The role of mitochondrial dysfunction in the stabilization of the glaucomatous process].

Unlabelled: Many key aspects of retinal ganglion cell (RGC) neurodegeneration in glaucoma are associated with mitochondrial dysfunction. Understanding the mechanisms and relationships between structural and functional changes in mitochondria would be beneficial for developing mitochondria-targeted therapeutic strategies to protect RGCs from glaucomatous neurodegeneration.

Purpose: This study determines the extent of mitochondrial dysfunction in patients with primary open-angle glaucoma (POAG) and evaluates the potential for stabilizing the glaucomatous process by improving mitochondrial functional activity and energy production by therapy with Mexidol and Mexidol FORTE 250.

[Peripheral nerves' function recovery by intratissual electric stimulation].

Unlabelled: An intratissual electrical stimulation, accompanied by irritation of their central neurons, is used to recover the function of damaged peripheral nerves. Treatment results exceeded those with the use of cutaneous electrical stimulation, which is confirmed by comparative results of trial animal experiments. The time and quality of peripheral nerves' function recovery in comparison of intratissual and cutaneous electrical stimulation methods remain unknown.

Effect of on Liver Diseases: A Systematic Review.

We aimed to systematize the results of published studies on the use of (SB) for the treatment of various liver disorders (CRD42022378050). Searches were conducted using PubMed and Scopus on 1 August 2022. The PubMed search was updated on 15 June 2024.

Growth Factors and Their Application in the Therapy of Hereditary Neurodegenerative Diseases.

Hereditary neurodegenerative diseases (hNDDs) such as Alzheimer's, Parkinson's, Huntington's disease, and others are primarily characterized by their progressive nature, severely compromising both the cognitive and motor abilities of patients. The underlying genetic component in hNDDs contributes to disease risk, creating a complex genetic landscape. Considering the fact that growth factors play crucial roles in regulating cellular processes, such as proliferation, differentiation, and survival, they could have therapeutic potential for hNDDs, provided appropriate dosing and safe delivery approaches are ensured.

The Role of Microvascular Obstruction and Intra-Myocardial Hemorrhage in Reperfusion Cardiac Injury. Analysis of Clinical Data.

Microvascular obstruction (MVO) of coronary arteries promotes an increase in mortality and major adverse cardiac events in patients with acute myocardial infarction (AMI) and percutaneous coronary intervention (PCI). Intramyocardial hemorrhage (IMH) is observed in 41-50% of patients with ST-segment elevation myocardial infarction and PCI. The occurrence of IMH is accompanied by inflammation.

[The role of astrocytes, circadian rhythms and light pollution in the pathogenesis of Alzheimer's disease].

Currently, more and more importance is being attached to the interaction of brain neurons with astrocytes in order to study the pathogenesis, and in the future, to develop methods for the prevention, early diagnosis and treatment of neurodegenerative diseases of the brain. In this review article, the authors attempt to demonstrate the role of astrocytes, disturbances in circadian rhythms, sleep-wake patterns, and light pollution in the development of Alzheimer's disease. Based on the analysis of literature data, possible mechanisms of synchronization and desynchronization of these processes are presented.

[Features of pain syndrome in vertebrogenic pathology in women].

Pain syndrome is one of the important problems faced by women, and its treatment requires an integrated approach, taking into account the individual characteristics of the female body. Currently, several hypotheses have been formulated to explain sex differences in the perception of pain, but they all have a number of contradictions. It has been established that pain syndrome occurs more often in women than in men and its prevalence increases with age.

[Diagnosis of psychogenic polydipsia in the type of clinical case].

Polydipsia is a pathologically increased thirst, satisfied by the intake of water in large quantities, which can manifest itself in various somatic or mental diseases and at first glance is similar to a true vasopressin deficiency. Central diabetes insipidus (CDI) is a disease of the hypothalamic-pituitary region characterized by the inability of the kidneys to reabsorb water and concentrate urine, which is based on a defect in the synthesis or secretion of vasopressin and is manifested by severe thirst and excretion of large amounts of hypotonic urine. The prevalence of the disease in the population is 1:25,000, which characterizes it as a fairly rare pathology of the hypothalamic-pituitary region.

Effect of Cold Adaptation on the State of Cardiovascular System and Cardiac Tolerance to Ischemia/Reperfusion Injury.

Despite the unconditional success achieved in the treatment and prevention of AMI over the past 40 years, mortality in this disease remains high. Hence, it is necessary to develop novel drugs with mechanism of action different from those currently used in clinical practices. Studying the molecular mechanisms involved in the cardioprotective effect of adapting to cold could contribute to the development of drugs that increase cardiac tolerance to the impact of ischemia/reperfusion.
