RESUMO

The purpose of this inquiry is to provide a conprehensive summary and analysis of the literature concerning the pharmacological properties of components that can be extracted from Desmodium styracifolium, a preparation in Chinese medicine. This study also aims to explore their potential application in elaborating medicinal products for the effective prevention and treatment of such conditions as urolithiasis, cholelithiasis, type 2 diabetes mellitus, metabolic syndrome, pro-oxidant and inflammatory processes, etc. Several experimental studies confirmed the potential of D. styracifolium to influence mineral metabolism, to decrease the concentration of constituents involved in the formation of urinary calculi, and to reduce mineral encrustation in the urinary tract, as well as to alleviate the damage caused by crystal structures. This beneficial impact is achieved through a combination of antioxidant and anti-inflammatory actions, along with urine alkalinization. The cholelitholytic, choleretic, and hepatoprotective effects of D. styracifolium plants have been confirmed, primarily ascribed to the activation of the hepatic Xα receptor and the bile acid receptor, farnesoid X receptor, by the flavonoid shaftoside. Special attention is focused on the potential therapeutic applications of flavonoids derived from D. styracifolium for diseases associated with the development of chronic inflammation and systemic response, emphasizing the ability of flavonoids to exert antioxidant and anti-inflammatory effects by acting directly and through the modulation of transcription factors. It is concluded that new strategies for the prevention and treatment of urolithiasis, cholelithiasis, type 2 diabetes mellitus, metabolic syndrome, acute and chronic inflammatory processes may rely on the promising development of dosage forms of D. styracifolium with their subsequent preclinical and clinical trials.

RESUMO

Post-traumatic osteoarthritis (PTOA), a disorder of the synovium, subchondral bone, and cartilage that affects the entire joint, constitutes approximately 12% of all cases of symptomatic osteoarthritis. This review summarizes the pathogenetic mechanisms that underlie the positive influence of chondroitin sulphates (CSs) on PTOA as means of preventive and therapeutic treatment. Mechanisms of PTOA development involve chondrocytes undergoing various forms of cell death (apoptosis, pyroptosis, necroptosis, ferroptosis and/or necrosis). Chondroitin sulphates are a class of glycosaminoglycans that improve the structure and function of cartilage and subchondral bone, which is associated with their ability to decrease the activation of NF-κB and p38 MAPK, and up-regulate Nrf2. Standardized small fish extract (SSFE) is an example of the drugs that can attenuate NF-κB-mediated systemic inflammation, potentially helping to reduce joint inflammation and cartilage degradation, improve joint function, and alleviate pain and disability in patients with these conditions.

RESUMO

One of the adverse outcomes of acute inflammatory response is progressing to the chronic stage or transforming into an aggressive process, which can develop rapidly and result in the multiple organ dysfunction syndrome. The leading role in this process is played by the Systemic Inflammatory Response that is accompanied by the production of pro- and anti-inflammatory cytokines, acute phase proteins, and reactive oxygen and nitrogen species. The purpose of this review that highlights both the recent reports and the results of the authors' own research is to encourage scientists to develop new approaches to the differentiated therapy of various SIR manifestations (low- and high-grade systemic inflammatory response phenotypes) by modulating redox-sensitive transcription factors with polyphenols and to evaluate the saturation of the pharmaceutical market with appropriate dosage forms tailored for targeted delivery of these compounds. Redox-sensitive transcription factors such as NFκB, STAT3, AP1 and Nrf2 have a leading role in mechanisms of the formation of low- and high-grade systemic inflammatory phenotypes as variants of SIR. These phenotypic variants underlie the pathogenesis of the most dangerous diseases of internal organs, endocrine and nervous systems, surgical pathologies, and post-traumatic disorders. The use of individual chemical compounds of the class of polyphenols, or their combinations can be an effective technology in the therapy of SIR. Administering natural polyphenols in oral dosage forms is very beneficial in the therapy and management of the number of diseases accompanied with low-grade systemic inflammatory phenotype. The therapy of diseases associated with high-grade systemic inflammatory phenotype requires medicinal phenol preparations manufactured for parenteral administration.

RESUMO

OBJECTIVE: Introduction: Medical researchers, who are non-native English speakers, are facing now the growing need to publish their research results in international journals switching to an English-only policy, to apply for grants and scholarship, but at the same time this puts many authors whose native language is not English at a disadvantage compared to their English-speaking counterparts. The aim: This paper aims at analysing the existing parameters of academic writing proficiency of medical undergraduate and postgraduate students; elucidating current approaches to develop academic writing competency and to promote academic multi-literacy of junior researchers, and outlining the general recommendations to improve the quality and sophistication of their writing by incorporating the principles and achievements of academic writing pedagogy into the system of medical training. PATIENTS AND METHODS: Materials and methods: This study is an empirical applied research of a qualitative type mainly based on data elicited from informants (n=120) of the Ukrainian Medical Stomatological Academy aged from 20 - 35. RESULTS: Results and conclusions: All participants were able to identify personal problem areas, and virtually all they note dissatisfaction with the use of English in their scholarly writing. They stated the obvious difficulties in sentence patterns and keeping tone of scientific narrative format. Writing in genres other than original research articles seems to be quite demanding and is often associated with the lack of self-confidence and language anxiety. Attention to developing academic writing skills should focus on the basic elements of academic writing, characteristics of written genres across the disciplines, providing a framework in which expert and practical knowledge is internally organized.
