The search for new protein kinase inhibitors is an effective approach in the struggle against cancer. However, the existing protein kinase inhibitors may have limitations in their effectiveness or may produce undesired side effects. Therefore, the development of new methods for searching for new inhibitors, which should be more effective and safe, is a topical issue. One of the promising areas is the use of molecular modeling to search for new protein kinase inhibitors.","PeriodicalId":41726,"journal":{"name":"Cardiometry","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139305030","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The relative biological effectiveness (RBE) of accelerated protons is about 1.1, as follows from the results of experimental studies of clonogenic survival of tumor cells in vitro. But however, despite the low RBE of proton radiation, a number of clinical studies have shown a significant increase in relapse-free and overall survival of patients after proton therapy compared with that after standard radiotherapy using photon radiation. The mechanisms, on which the differences recorded in vivo are based, are of significant scientific and practical interest, but have been poorly studied.","PeriodicalId":41726,"journal":{"name":"Cardiometry","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139305612","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Some of the most developed cellular models are structures obtained using three-dimensional bioprinting, which include not only malignant cells, but also biogels to imitate the chemical and mechanical properties of the extracellular matrix of the tumor.","PeriodicalId":41726,"journal":{"name":"Cardiometry","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139292430","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Molecular genetic testing to examine genetic abnormalities in tumor cells has been increasingly using in oncology. With an accumulation of the data on the repertoire of mutations or other events in the patient’s tumors, new goals for the development of more targeted and specific antitumor therapies appear. For example, membrane proteins EGFR, HER-2, PSMA and C-met are identified as such targets. Despite the large volume of research conducted, no more than 11% of the total drug candidates are approved by regulatory authorities for clinical use. This is often due to their lack of effectiveness and the incomparability of the results obtained in preclinical trials in animal models with actual results in patients. Therefore, the development of experimental approaches for modeling tumor processes in laboratory animals is an urgent problem.","PeriodicalId":41726,"journal":{"name":"Cardiometry","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139292624","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It has been established that stress causes an increased incidence of malignant tumors and also worsens the prognosis in patients with already existing tumors. Among the mechanisms of carcinogenesis under stress, there is an increase in the level of cortisol, which has a significant inhibitory effect on the immune system and the secretion of pro-inflammatory interleukins. Post-traumatic stress disorder (PTSD) involves inactivation of the hypothalamic-pituitary-adrenal (HPA) axis and decreased secretion of cortisol in humans, or corticosterone in rats and mice. However, the question of whether PTSD is a risk factor for the development of cancer or tumor growth remains practically undeveloped.","PeriodicalId":41726,"journal":{"name":"Cardiometry","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139295405","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Damage to the blood-brain barrier and the endothelium of blood capillaries can cause dysfunction of neurons in the cerebral cortex, induce changes in neural plasticity, cognitive functions and result in the development of depression. Depression is observed in 20% of the cancer patients, and it affects quality of life, treatment effectiveness and survival.

High rates of gastritis in children are associated with poor nutrition, physical inactivity, drug abuse, bad habits, a number of concomitant diseases, immune disorders, allergization of the body, and stress. Although a significant proportion in the structure of chronic gastritis is occupied by gastritis associated with Helicobacter pylori infection, many clinical forms are diagnosed that are not associated with the presence of a microbial pathogen in the gastric mucosa. The goal is to highlight the problem of chronic gastritis in children, including risk factors, etiology, clinical manifestations, diagnosis and treatment. Materials and methods. To achieve these goals, a literature search was carried out in the PubMed and Google Scholar databases. The search depth did not exceed 5 years. Uninformative and duplicate articles were excluded. The final list of references included 42 articles. Results. In addition to traditional risk factors for adults, the incidence of chronic gastritis in children is influenced by artificial feeding, pathology of pregnancy and childbirth, respiratory infections, decreased mobility, and concomitant pathology. Helicobacter pylori infection is detected in 56% of children referred to a gastroenterologist for gastrointestinal symptoms. Manifestations of gastritis vary from asymptomatic to epigastric pain with dyspeptic symptoms. Conclusion. 1) Currently, up to 30-40% of children suffer from chronic gastritis. 2) Triple therapy regimens are traditionally used to eradicate Helicobacter pylori, but quadruple therapy is used in populations with high resistance to antimicrobial drugs. 3) In the treatment of eosinophilic gastritis, the drugs benralizumab and vedolizumab demonstrate high effectiveness, leading to depletion of the pool of eosinophils in the blood and tissues of the stomach, as well as clinical improvement. 4) Effective treatment for collagen gastritis has not yet been developed. The treatment regimen includes an elimination diet, proton pump inhibitors, and iron supplements.","PeriodicalId":41726,"journal":{"name":"Cardiometry","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139292271","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
