Background: The annual incidence of pulmonary thromboembolism is reported to be 39–115 cases per 100,000 population, with rates of 60–120/100,000 in Western countries and 10–20/100,000 in Asian countries. In Mongolia, few studies revealed the prevalence of risk factors and clinical manifestations of acute pulmonary embolism. Over the past 30 years, the incidence of risk factors for non-communicable diseases, which are mainly triggered by lifestyle and social parameters, has rose. Moreover, environmental conditions such as cold climate, hypoxia, and blood hyperviscosit may contribute to higher incidences of acute pulmonary embolism in high-altitude regions. This condition is potentially fatal and can become impair quality of life. Aim: We aimed to compare risk factors and clinical characteristics based on age and sex, and to evaluate laboratory findings and diagnostic tests among Mongolian patients diagnosed with acute pulmonary embolism. Materials and Methods: This retrospective research included total 232 patients meeting inclusion criteria. The information was collected from patient histories, including general demographics, risk factors, comorbidities, symptoms, and physical examination findings. Laboratory analyses included complete blood count, coagulation profile, and immunological markers (D-dimer, NT-proBNP, troponin, protein C, homocysteine, and C-reactive protein), as well as selected imaging parameters. We used Wells and Geneva scoring systems to assess probability of acute pulmonary embolism and Pulmonary Embolism Severity Index to determine disease severity. Differences by age and sex were analyzed using independent t-tests for continuous variables and chi-square tests for categorical variables. Results: Among participants with acute pulmonary embolism, the prevalence of tobacco and alcohol use was significantly higher among males (p<0.001). Among comorbidities, arterial hypertension and other pulmonary diseases were more common in males, whereas cardiac diseases were more frequent in females (p=0.028). Participants aged 65 years and older showed higher rates of comorbid conditions and regular medication use (p<0.001). The most common symptoms were dyspnea (90.9%), chest pain (74.2%), cough (70.5%), leg pain (38.9%), hemoptysis (20.7%), and cyanosis (9.3%). According to sPESI scoring, 69.8% (n=162) were at high risk of death within 30 days, with no significant difference by sex. However, mortality risk within 30 days was significantly higher in participants aged 65 years and above (p<0.001). As increasing age, the neutrophil-to-lymphocyte ratio and platelet-to-lymphocyte ratio were elevated, indicating an acute inflammatory response (p=0.001). Contrast-enhanced CT scans revealed that 95 participants (44.2%) had main pulmonary artery involvement, with no significant sex difference, though involvement of the main pulmonary artery was more frequent in those aged 65 and older. Conclusion Dyspnea, chest pain, and cough were the most common symptoms among patients diagnosed with acute pulmonary embolism. The 30-day mortality risk associated with it was higher among males and increased with advancing age.

Abstract Secondary metabolites present in the plants are predominantly responsible for treating various ailments. Secondary metabolites are also called as plant constituents or natural compounds which exert significant pharmacological and toxicological effects in humankind. The chemical compounds present in the plant sources are categorized as primary and secondary metabolites based on the chemical structure and biosynthetic derivation. These substances are called plants secondary metabolites. One of the most important of secondary metabolites is Tannins. Tannins are phenolic compounds, secondary metabolites of plants widespread in terrestrial and aquatic natural environments. As they can be found in plenty of plants and herbs, they have been traditionally used for medicinal and other purposes, such as the leather industry. This fact is explained by the fact that they exert plenty of different biological activities and, thus, they entail a great potential to be used in the food, nutraceutical, and pharmaceutical industry.
Among the biological activities of tannins, the most relevant ones are antioxidant, anti-inflammatory, anti-diabetic, cardioprotective, healing and antimicrobial (antiviral and antibacterial)
Consequently, this review article is directed towards the description of the biological activities exerted by tannins as they could be further extracted from by-products of the agri-food industry to produce high-added-value products.

Abstract Trees and shrubs of the genus Betula (Betulaceae) inhabit various ecosystems in temperate and boreal climate zones of the northern hemisphere. The healing properties of Betula bark and bark extracts have been known for a long time in traditional medicine in different parts of the world. Several species of Betula have traditionally been used for the treatment of various inflammatory diseases including arthritis. The purpose of this review is to provide updated, comprehensive and categorized information on the botany, traditional uses and phytochemical research of Betula species in order to explore their therapeutic potential and evaluate future research opportunities.

Background:We determined lipid parameters which are the leading causes of developing cardiovascular diseases and atherosclerosis and investigated the increased serum triglyceride level which is referred to as atherogen triad , decreased high-density lipoprotein and increased low- density lipoprotein associating with age and sex.Method:237 people who were done lipid level parameter tests in the Central Hospital Laboratory were involved in the study. We identifed cholesterol, triglyceride, lowdensity lipoprotein (LDL) and high-density lipoprotein ( HDL) (COBASC-311,ROCHE,Germany) which are the lipid parameters using full automatic apparatus .Results:While serum cholesterol level increased in the ages between 40-60 and has a tendency to decrease in the further, HDL level was decreasing as the age grew. Serum LDL level has strong direct relevance to cholesterol (r=0.720, p<0.01) and weak relevance to triglyceride (r=0.189,p<0.01). As for the sex, high- density lipoprotein level decreased for men with statistical importance (p<0.05) and there was no signifcant difference in other parameters. LDL level increased for 81.8% , increased cholesterol for 51.1%, raised triglyceride for 27.9% comparing with the normal rate but HDL level was decreased for 32.2% of the participants in the study. These changes mostly occurred at the ages of 40-60. Atherogen triad occurred for 16.5% of the participants and 13(33.3%) of whom were male and 26(66.7%) female.Conclusion:LDL and cholesterol level raised more than the normal rate comparing with other lipid parameters particularly as for 40-60 aged people and atherogen triad which leads to develop atherosclerosis occurs in 16.5% of all adults in the study.
