Background: More than 60 zoonotic diseases can be transmitted from dogs (Canis lupus familiar’s) to humans, one of which is cystic echinococcosis (CE). Approximately 270 million people in Central Asia live in areas at risk for CE, and Mongolia is included in this region. The transmission of zoonotic infection is facilitated by the movement of humans, livestock, and dogs, as well as trade and cross-border interactions between countries. Aim: To determine the helminth fauna in the dog populations of selected soums of Bayan-Ulgii Province, identify zoonotic pathogens, and investigate Taeniidae infection. Materials and Methods: Seven soums of Bayan-Ulgii province bordering the Russian Federation and the People’s Republic of China were selected using a targeted sampling approach. Domestic dogs belonging to 300 individuals who underwent abdominal ultrasound screening for cystic echinococcosis were included after obtaining consent for deworming. Anthelmintic treatment (5 mg/kg) was administered, and fecal samples from 95 dogs were collected post-treatment. Helminth eggs were identified to determine the helminth fauna. DNA was extracted from samples positive for Taeniidae eggs using a DNA extraction kit (Qiagen, Stool DNA kit, Germany). The mitochondrial cox1 gene was amplified by PCR using F/COI and R/COI primers to determine infection status. Results: The helminth fauna of the dog population in Bayan-Ulgii province consisted of members of the Taeniidae family and the genus Ascaris, as well as Toxocara canis, Trichuris vulpis, Macracanthorhynchus catulinus, Oncicola canis, Strongyloides canis, and Alaria canis. Prevalence rates were as follows Taeniidae 10.5%, T. canis 4.2%, S. canis 3.2%, A. canis 2.1%, Ascaris 2.1%, T. vulpis 2.1%, O.canis 3.2%, M. catulinus 5.2%. Among these, T. canis, T. vulpis, A. canis, and members of the Taeniidae family are zoonotic parasites transmissible from dogs to humans. DNA was extracted from 10 samples positive for Taeniidae eggs. Amplification of the cox1 gene using COI primers revealed an 880 bp band in 9 samples (90%), confirming infection. Conclusions 1. The helminth fauna of dogs in selected soums of Bayan-Ulgii Province consisted of helminths belonging to 1 family, 1 genus, and 6 species. 2. Taeniidae infection was detected in 9.0% of dogs in the selected soums of Bayan-Ulgii Province.

Background: The family Taeniidae (Ludwig, 1886) belongs to the class Cestoda, phylum Platyhelminthes, and order Cyclophyllidea. Zoonotic parasites within this family, particularly Taenia and Echinococcus species, impose a significant socio-economic burden in developing countries. Aim: To determine the prevalence of Taeniidae infection in the domestic dog population of selected soums in Sukhbaatar Province and to identify associated risk factors. Materials and Methods: A total of 135 domestic dogs from seven soums bordering China in Sukhbaatar Province were dewormed, and post-treatment fecal samples were collected for the detection of Taeniidae eggs. DNA was extracted from egg-positive samples using the QIAamp Fast DNA Stool Mini Kit (QIAGEN, Germany). The cox1 gene was amplified using F/COI and R/COI primers through polymerase chain reaction (PCR) to confirm infection. Associations between Taeniidae infection and potential risk factors were analyzed using univariate and multivariate logistic regression analyses. Results: Taeniidae eggs were detected in 35 of 135 fecal samples (25.9%). The mean number of eggs per gram of feces varied among samples. PCR amplification confirmed Taeniidae infection in 30 of the 35 egg-positive samples (85.7%), producing an 880-base pair fragment. The analysis revealed that several owner-related and management-related factors were significantly associated with an increased risk of Taeniidae infection in domestic dogs, including type of residence (OR=12.18; 95% CI: 1.51-98.89; p<0.019), allowing dogs to roam freely (OR=8.08; 95% CI: 2.19–29.73; p<0.002), and feeding dogs raw livestock viscera (OR=265.12; 95% CI: 16.2-4561.7; p<0.0001). Conclusion A 22.2% prevalence of Taeniidae infection was identified among domestic dogs in selected soums of Sukhbaatar Province. Household living conditions, allowing dogs to roam freely without restraint, and feeding dogs raw livestock organs and offal were identified as significant risk factors associated with Taeniidae infection.

Background: In recent years, natural compounds have been shown to play an important role in cancer prevention and early-stage therapy. Flavanones, a class of polyphenolic compounds present in plants, vegetables, seeds, fruit peels, and flowers, have been identified to possess anticancer, antioxidant, anti-inflammatory, and antibacterial bioactivities. Cancer has become a major global economic and public health challenge. According to international statistics, one in four individuals (22.8%) die from non-communicable diseases, while one in six (16.8%) die from cancer. Aim: To investigate the effect of a flavanone (5,2’,3’-trihydroxy-6,7-methylenedioxyflavanone) isolated from Iris tenuifolia on the migration of liver cancer cells. Materials and Methods: The study was conducted at the Institute of Biomedicine, Mongolian National University of Medical Sciences. The effect of the flavanone (5,2’,3’-trihydroxy-6,7-methylenedioxyflavanone) on cancer cell migration was evaluated in vitro using the scratch assay. Human liver cancer cells (HepG2) were revived and stabilized before experiments were performed. Results: HepG2 cells were treated with a 2.5 μg/mL concentration of the flavanone for 24 hours. In the control group, an initial scratch width of 0.9 mm was reduced to 0.65 mm after 24 hours due to cell proliferation and migration into the denuded area. However, treatment with the 2.5 μg/mL flavanone concentration resulted in the complete inhibition of cell migration. Conclusion The flavanone isolated from Iris tenuifolia effectively suppresses the migration of liver cancer cells.

Results: We treated A549 cancer cells with different concentrations of flavanone (1.25 μg/ml, 2.5 μg/ml) for 24 hours and analyzed them using the scratch assay. A cell-free gap of 0.9 mm in width was created, and after 24 hours, A549 cells migrated and proliferated into the gap, reducing its width to 0.25 mm. Treatment with 2.5 μg/ml flavanone completely inhibited cell migration. Conclusion Flavanone isolated from Iris tenuifolia inhibits lung cancer cell migration in a doseand time-dependent manner.

Background: In recent years, scientists have found that certain natural compounds have significant potential in cancer prevention and early-stage cancer treatment. Flavanones, a class of polyphenolic compounds found in plants, vegetables, seeds, fruit peels, and flowers, have been identified to possess anticancer, antioxidant, anti- inflammatory, and antibacterial bioactivities. Cancer has become a major global challenge in terms of both economic and public health concerns. Global statistics indicate that 22.8% of deaths are attributed to non-communicable diseases, and 16.8% are caused by cancer, accounting for one in four and one in six deaths, respectively. Aim : To investigate anticancer effects of Iris Tenuifolia-derived flavanone on cancer cell lines. Materials and Methods : The study was conducted at the Bio-Medical Research Institute of the Mongolian National Uni versity of Medical Sciences, investigating the effect of flavanones on cancer cell viability under in vitro conditions using the MTT assay. In the study, colon, liver, and lung cancer cells were cultured, stabilized, and used for the experiments. Colorectal cancer cells (MC38), liver cancer cells (HepG2), and lung cancer cells (A549) were revived, cultured, and stabilized for use in the experimental procedures. Statistical analysis of the results was performed using Microsoft Excel 2010, and graphs were generated using GraphPad Prism 8. Differences between groups were analyzed using Student’s t-test, and a p-value of <0.05 was considered statistically significant. Results : We treated MC38, HepG2, and A549 cancer cells with different concentrations of flavanone (2.5 µM, 5 µM, and 10 µM) for 24 to 48 hours to evaluate cell viability. Flavanone inhibited A549 cell viability by 2.5 μM-10%, 5 μM-25%, and 10 μM-38%, respectively. For HepG2 cells, flavanone treatment at concentrations of 5-10 µM reduced cell viability by 28–58%. No statistically significant effect on the viability of MC38 cells was observed following treatment with flavanone at concentrations ranging from 2.5 to 10 µM. Additionally, although MC38 inhibited cell viability in a dose-de pendent manner in cell cultures, it had a statistically significant effect at higher concentrations of 30-200 μM (p<0.01). Conclusion Flavanone inhibits the cancer cell viability in a dose and time dependent manner

Abstract Malaria is an ancient disease caused by parasites of the genus Plasmodium and transmitted by several species of female anopheline mosquitoes. The term „malaria‟ originates from mal’aria (Italian) –signifying „bad air‟ or miasmas arising from marshes.
Cognizant of the burden of the disease in antiquity, several efforts have been made to understand the disease notably, the detection of the Plasmodium parasite in the blood of infected humans in 1880, as well as proof of the complete life cycle of malaria parasites in mosquitoes in 1897.
Among 200 Plasmodium species identified P. falciparum, P. vivax, P. ovale, P. malariae and P. knowlesi are known to be responsible for human malaria, while mortality due to malaria is mostly attributed to infections with P. falciparum.
The Anopheles mosquito bites a human and injects sporozoite forms. These move to the liver and invade hepatocytes, in which they develop to produce exoerythrocytic merozoite forms that are released into the blood stream. Merozoites invade erythrocytes and grow into trophozoites and mature schizonts. Merozoites are released that reinvade new erythrocytes.
Gametocytes, formed from the asexual blood stage, are taken up by a feeding mosquito into the gut where they mature to form male and female gametes. The fertilized zygote develops to an ookinete and an oocyst and finally sporozoites that migrate to the salivary glands.
Malaria transmission exits in 99 countries throughout world, and the greater burden of the disease is carried by African countries. According to the World Health Organization (WHO), the estimated cases of and deaths due to malaria in 2016 were 219 million and 660,000, respectively with malaria deaths steadily decreasing since 1980. Despite the decline in the burden of malaria with the scaling-up of interventions the fact that the estimated (uncertainty exists) number of malaria deaths in 2016 exceeded that of 1980 calls for more efforts in the prevention and control of the disease.
Mongolian troops have been participating at UN mission since 2003. They work very complicated condition. One of the simple risks is Malaria. We had approximately 80 cases who had been infected by malaria at the mission area.
Mongolia is land without malaria infection. But our tourists can visit all of the world and troops works on mission area in Africa. They have a risk of malaria and our doctors have to be diagnosis and treat to malaria cases. This article provides an overview of malaria laboratory diagnosis and epidemiological data that will lead to the development of strategies to diagnose and reduce infection.

Background: Cigarette smoking is known to reduce appetite and body weight. This effect is mainly mediated by nicotine. Quit smoking without nicotine replacement therapy often result in increased body weight. Even though number of studies explored different levels of effects of smoking, there are few studies which address short-term effect of smoking on metabolism. Aim: To study short-term effect of smoking on appetite, body weight and blood glucose level of mice (Experimental animal) Objectives:
- To study effect of smoking on appetite
- To study effect of smoking on body weight
- To study effect of smoking on blood glucose and anxiety Methods: Inbred strain, Balb/c mice (n=20) were used. Mice were divided into two groups control (n=7) and treatment (n=9) group. Smoking treatment conducted in 5 days consequently in treatment group, three times a day with cigarette smoke. During experiment both control and treatment groups were monitored for food intake, water intake, body weight. In the end of the experiment blood glucose and anxiety levels were measured. In addition, liver, white adipose tissue and brown adipose issue were sampled comparison. Results: Short-term (5 days) treatment of smoking of treatment group result in significant difference in food and water intake (p<0.05) as well as tendency to lowering blood glucose and reduction of mesenterial, perirenal, epidydimal, white adipose tissues and brown adipose revealed tendency to reduction of mesenterial white adipose with control group. (Mes. White adipose tissue weights 0.44g in control group, 0.23g in treatment group). There was not significant difference in blood glucose test and anxiety test evaluated by time spent on alleys and transition between alleys in two groups. Conclusion
1. Cigarette smoking significantly reduced food and water intake in mice (or experimental animal).
2. Smoking didn’t affect body weight, but inhibited normal body weight gain.
3. Short-term treatment of smoking was not enough to change blood glucose level and anxiety behavior of mice.

Trichomonas vaginalis is a flagellated protozoan parasite that causes vaginitis and cervicitis in women and asymptomatic urethritis and prostatitis in men. Mast cells have been reported to be predominant in the vaginal smears and vaginal walls of patients infected with T. vaginalis. Mitogen activated protein kinase (MAPK) activated by various stimuli also regulate the transcriptional activity of various cytokine genes in the mast cells. Because of their essential role in intracellular signaling network, also appropriate targets for pharmacological treatment of inflammatory disorders.Cultivation of T.vaginalis and HMC-1 line, preparation of TvSP, to check intracellular ROS level and degranulation by FACS, to determine phosphorylation of MAPK and p47phox by immunobloting.In this study, we investigated whether MAPK were involved ROS generation and exocytotic degranulation in HMC-1 induced by T. vaginalis-derived secretory products (TvSP). We first examined that TvSP could induce activation of MAPK and NADPH oxidase in HMC-1 cells. Stimulation with TvSP induced phosphorylation of MAPK and p47phox in HMC-1 cells. Phosphorylation of p47phox is main source of ROS generation. Next, to determine involvement activation of MAPK in ROS generation and degranulation in HMC-1 cells induced by TvSP. ROS generation is required for exocytotic degranulation of mast cells induced by TvSP. Stimulation with TvSP induced phosphorylation of p47phox, ROSgeneration, and surface up-regulation of CD63 in human mast cells. CD63 is a marker for exocytosis. Pretreatment with MAPK inhibitors strongly inhibited TvSP-induced ROS generation and exocytotic degranulation.Our results suggest that TvSP could induce intracellular ROS generation and exocytotic degranulation in HMC-1 via MAPK signaling pathway.
