Anti - proliferative and anti - inflammatory activity of triterpene extracts from plant species belonging to Lamiaceae family / Actividad antiproliferativa y antinflamatoria de los extractos de triterpenos de plantas pertenecientes a la familia Lamiaceae

Triterpenes are very important secondary metabolites with wide structural diversity and significant role in pharmacy and medicine. In the present research, a comparative study of pharamacological activities of the triterpene fractions obtained from several plant species belonging to Lamiaceae family, was carried out. In - vitro anti - proliferative activity was performed using a standard proliferation assay based on tetrazolium salts. In vitro anti - inflammatory activity of triterpene fractions was determined by an assay of inhibition of albumin denaturation. In general, the triterpene fractions obtained from plant species belonging to Lam iaceae family showed a strong anti - proliferative activity and anti - inflammatory activity. The triterpene fraction of Rosmarini folium showed the strongest anti - proliferative activity (GI 50 range from 4 to 37 µg/ml) and the strongest anti - inflammatory activ ity in the range from 57.27% to 80.69%. This comparative study provides scientific evidence to support the traditional use of Lamiacae plant species for medical purposes as anti - inflammatory and anti - proliferative medicines.

Los triterpenos son metabolitos secundarios muy importantes, con una amplia diversidad estructural y un rol significativo en la farmacia y la medicina. En esta investiga ción, se realizó un estudio comparativo de las actividades farmacológicas de las fracciones de triterpenos obtenidas de varias especies de plantas pertenecientes a la familia Lamiaceae. La actividad antiproliferativa in vitro se realizó mediante un ensayo estándar de proliferación basado en sales de tetrazolio. Se determinó la actividad antinflamatoria de las fracciones de triterpeno s mediante un ensayo de inhibición de desnaturalización de la albúmina. En general, las fracciones de triterpeno s obtenidas de las plantas pertenecientes a la familia Lamiaceae mostraron una actividad antiproliferativa y antinflamatoria fuerte. La fracción de triterpeno de Folium Rosmarini mostró la actividad antiproliferativa más fuerte (rango GI 50 entre 4 y 37 µg/m L ) y la más f uerte actividad antinflamatoria en el rango de 57,27% a 80,69%. Este estudio comparativo provée evidencia científica para apoyar el uso tradicional de especies de plantas Lamiaceae para usos médicos como medicinas antinflamatorios y antiproliferativas.

Knowledge and Attitudes regarding Covid-19 Vaccination among Medical and Non-medical Students in Bosnia and Herzegovina.

OBJECTIVE: The aim of this study was to investigate students' knowledge, attitudes and hesitancy regarding COVID-19 vaccination. METHODS: A cross-sectional questionnaire-based survey was conducted among a total of 1282 medical students and 509 non-medical students at four public universities in Bosnia and Herzegovina: Tuzla, Sarajevo, Banja Luka, and Mostar. RESULTS: A significantly higher rate of vaccination was observed in the group of medical students as well as a higher level of knowledge about vaccination in general and vaccines against the COVID-19 disease. Students who received the COVID-19 vaccine had a higher level of knowledge about vaccination in general and COVID-19 vaccines in particular compared to the non-vaccinated students in the medical and non-medical groups, respectively. Furthermore, vaccinated students, regardless of the course they are taking, showed generally stronger positive attitudes compared to non-vaccinated students, regarding the safety and effectiveness of the COVID-19 vaccine. Both groups of students believe that the rapid development of the vaccine is contributing to refusal or hesitancy to receive a vaccine against COVID-19. Social media/networks were the main sources of information about the COVID-19 vaccine. We did not find any contribution of social media to the reduced level of COVID-19 vaccine coverage. CONCLUSION: Education of students about the benefits of the COVID-19 vaccine will lead to its better acceptance as well as the development of more positive attitudes towards vaccination in general, especially having in mind that students are the future population of parents, who will make decisions about vaccinating their children.

The Moisturizing Efficacy of a Proprietary Dermo-Cosmetic Product( CLS02021) Versus Placebo in a 4-week Application Period.

Background: Studies suggest that applying probiotic skincare products may have beneficial effects on the skin due to bacteria competitiveness and specific metabolites produced by probiotics. The cream CLS02021 is a postbiotic blend of metabolites, including organic acids, enzymes, and peptides that are a result of the co-fermentation of three proprietary probiotic strains and is specific for its high concentration of the enzyme Sphingomyelinase which plays a significant role in cell signaling pathways and ceramide production. Objective: The aim of this study is to evaluate the cosmetic effects of probiotic-derived Ingredient CLS02021 and its safety in healthy volunteers. Methods: Fifty healthy volunteers between 18 and 69 years old were recruited to participate in this multicentric, randomized, intra-individual, double-blind group study. Following a face-split design, volunteers applied both face cream containing CLS02021 on one side of their face and a placebo cream on the other side of their face for a total duration of four weeks, two times a day. Evaluation of the cosmetic effects included instrument measurements of moisturizing, elasticity, wrinkle depth, sebum production, pore size, melanin production, sensitivity, and side effects. Results: A significant difference of CLS02021 over the placebo group was observed for moisture and elasticity increase (both p<0.001), pore size (p<0.01), and a wrinkle depth decrease (p<0.05). No significant differences were noted in sebum production, melanin level, skin cleanliness, and sensitivity between groups. Conclusion: CLS02021, as a probiotic-derived ingredient, showed strong beneficial effects on skin moisture and elasticity increase, wrinkle depth, and pore size reduction. Face cream containing CLS02021 is well tolerated and could be an organic choice for cosmetic hydrating and antiaging skincare treatment.

Comparison of the Effects of Allopurinol and Febuxostat on the Values of Triglycerides in Hyperuricemic Patients.

INTRODUCTION: Hyperuricemia is an independent risk factor for the development of many diseases. AIM: The aim of this paper is to compare the effects of allopurinol and febuxostat on the values of triglycerides and uric acid in hyperuricemic patients. METHODS: This was a pharmacological-clinical retrospective-prospective study. The research sample comprised 50 examinees of both genders and different ages who were undergoing allopurinol (100 mg/day) or febuxostat (80 mg/day) therapy. Statistical Product and Service Solutions (SPSS) Software and Microsoft Excel were used for statistical analysis. RESULTS: Examinees who were treated with allopurinol had a statistically significant decrease in uric acid concentrations (by 126.28 ± 20.36 µmol/l) at the end of the observation compared to the initial values (p = 0.006). Examinees who were treated with febuxostat had a statistically significant decrease in uric acid concentrations (by 252.80 ± 94.17 µmol/l) at the end of the observation compared to the initial values (p = 0.001). The initial value of triglycerides was 1.58 ± 0.64 mmol/l in allopurinol-treated examinees, and 1.60 ± 0.52 mmol/l in febuxostat-treated examinees. After three and six months of allopurinol use, there was a statistically significant increase in triglyceride values (p = 0.046 and p = 0.042, respectively). A statistically significant decrease in triglyceride values (by 0.16 ± 0.10 mmol/l) was noted after three months of febuxostat use (p = 0.012). CONCLUSION: The results of this research confirmed the previous findings and pointed out the positive pharmacological effects of allopurinol and febuxostat.
