Introduction: Cardiovascular diseases (CVDs) remain major problem in modern medicine. According to World Health Organization they are the leading cause of death. Despite increased awareness about impact of healthy lifestyle, mortality still remains on high level. Cardiovascular diseases requires multidisciplinary treatment. One of those aspects is determinate an appropriate diet. Purpose: The aim of this systemic review is to collect, evaluate and summarize the information on fasting mimicking diets and it is effect on therapy and prevention in cardiovascular diseases. Material and methods: Analysis and review of available literature. The search of articles in popular scientific databases such as PubMed, Google Schoolar WHO database State of knowledge: Risky behavior include unhealthy diet, tobacco use, physical inactivity, alcohol abuse. Those behaves lead obesity, raised blood pressure, hyperglycemia, dyslipidemia. Those factors have significant impact on the increase of cardiovascular diseases in the population. Fasting and calorie restriction are becoming more and more popular. Results: Many studies indicate that fasting mimicking diet can prevent from excessive fat accumulation, obesity, diabetes, dyslipidemia, hypertension As a result it decreases probability of cardiovascular diseases. Those diets not only support weight loss, but also can help maintain good health and extend lifespan.
Introduction Nitroxoline (NTX) is a well-known chemotherapeutic agent that has been used to treat urinary tract infections since the 1960s. Today, the incidence of multidrug-resistant (MDR) bacterial strains is on the rise worldwide. This has resulted in repurposing, whereby during the ongoing research on nitroxoline, the possibility of its wide use has been demonstrated, not only in treatment against resistant pathogens, but also potential broad anti-cancer applications. Aim of the study The purpose of our work was to review scientific articles and show the multi-potential - anti-pathogenic and anti-tumor use of nitroxoline. Methods and materials We reviewed the English-language literature in the PubMed database, using the key words: „Nitroxoline”, „Nitroxoline cancer”, „Nitroxoline antibacterial use” Results Analysis of studies has shown that nitroxoline, currently used in benign urinary tract infections, is also applicable in the treatment of urinary tract infections caused by multidrug-resistant bacteria (MRD). It is also active against drug-resistant fungi and mycobacteria. Repurposing has also demonstrated the anticancer effects of nitroxoline through inhibition proliferation, induction apoptosis of tumor cells and other mechanisms, making it likely that nitroxoline will be used in cancer treatment regimens in the future. Conclusion Nitroxoline has found widespread use in the treatment of urinary tract infections caused by multidrug-resistant bacteria (MRD) and by strains of resistant fungi, which in today's world are spreading and increasing their drug resistance. Repurposing has shown promising anticancer activity of nitroxoline in the treatment of urinary tract cancers and more. The data supporting the effects of nitroxoline seem promising, suggesting the rationale for future clinical trials to further our understanding of the exact mechanisms of action and use of nitroxoline in oncology treatment.
Introduction Cirrhosis is a condition in which the liver becomes fibrotic following damage to the liver and transforms the architecture of the organ into regenerative nodules. The disease is caused 30% by HCV infection, resulting in a risk of severe complications and death. Since the use of direct-acting antivirals ( DAAs) for the treatment of chronic HCV, sustained virological response (SVR) rates have begun to increase, even in treatment-resistant cases. Studies have also shown that DAAs may have applications in other viral diseases and even In the treatment of breast cancer. Aim of the study The purpouse of our study was to review scientific articles to show the efficiency and potential use of DAAs in the treatment of chronic HCV, and to identify possible directions for further research. Methods and materials We reviewed the English literature in the PubMed, using the key words: "simeprevir" ; "sofosbuvir" ; "velpatasvir" ; "telaprevir" ; "chronic hepatitis C". Results Studies have shown that the therapeutic regimens currently being designed with (DAAs) offer the possibility of treating almost the entire population with hepatitis C, while reducing side effects of interferon therapy such as increased AST, ALT activities, diarrhoea, vomiting, nausea and depression. They remain effective and tolerable, regardless of the stage of cirrhosis and associated serious co-morbidities. Analysis of studiem shows, that DAAs also show efficacy against other disease such as breast cancer, MRSA infections, SARS-CoV-2 or flavivirus infection. Conclusion All (DAAs) are effective in the treatment of patients with HCV, including cirrhosis. They result in significant improvements in prognosis and clinical outcomes. Promising results have been obtained in published data on the effect of DAAs against disease entities other than HCV, suggesting the rationale for future clinical trials to further the hypothesis of the increased potential of these drugs.
Introduction: Vitamin C (Vit C) is an organic chemical compound from the group of unsaturated polyhydroxy alcohols. It influences physiological processes such as the facilitation of iron absorption, hormone and carnitine synthesis, and is also involved in epigenetic processes. It is a vitamin, which means that it must be provided in food. It is also an antioxidant used as a food additive. In recent times, its pleiotropic use has been proven in the treatment of immune deficiencies, the treatment of skin diseases, bone diseases and may also be used in new cancer treatment regimens. Aim of the study: To review the current literature on the use of vitamin C in various fields of health and science. Materials and Methods: We reviewed the literature available in PubMed, using the key words: "vitamin C"; "ascorbid acid"; "cancer treatment"; "vitamin C immune function". Results: Vitamin C has pleiotropic effects on the human body, both through its effects on cells and tissues and through its antioxidant mechanisms and regulation of gene expression. It has been shown to be a key antioxidant with anti-inflammatory and immune system supportive effects. Its effect of slowing down skin photo-ageing by reducing the amount of metalloproteinases induced by reactive oxygen species has been noted in the literature. Vitamin C has been shown in studies to reduce the risk of osteoporosis due to its osteoclast inhibitory properties. Beneficial effects of high-dose intravenous infusions have also been demonstrated in the treatment of cancer, as well as about reducing organ failure and vascular damage in patients with ARDS and sepsis. Summary: The versatile action of vitamin C has made it the subject of intense research. However, the reports in the literature to date on its use require further studies on larger groups of people to confirm its effects.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
