Background: Basketball involves repeated high-intensity, explosive movements that depend largely on anaerobic energy systems. Accordingly, anaerobic capacity and body-composition parameters such as skeletal muscle mass and fat distribution are key determinants of performance. However, data-driven studies integrating conditioning training, anaerobic performance, and body composition in Mongolian professional players are limited, and the application of machine-learning approaches in this context remains underexplored. Aim: To examine the relationships between conditioning training, anaerobic capacity, and body composition in professional basketball players and to develop a machine-learning model for injury-risk prediction. Materials and Methods: Eleven healthy professional male basketball players (21–28 years) from the Omni Erdenet Miners were evaluated. Body composition was measured using the InBody 970, and anaerobic performance was assessed by a 30-s Wingate test on a Monark 894E ergometer. Measurements were obtained at three time points. Changes were analyzed using Friedman and Wilcoxon tests, while associations were examined by Pearson correlation and multivariate regression. Injury-risk models were developed using Random Forest and regression-based machine-learning methods. Research Ethics Committee, approval number 24-25/04-01 Result: Phase angle increased from 6.8±0.5 to 7.3±0.6° (p =0.021), and body-fat percentage decreased from 20.5±3.2% to 16.2±2.0% (p =0.015), with no change in skeletal muscle mass. Visceral fat decreased and anaerobic peak and mean power improved (p <0.05). Fat percentage was negatively correlated with anaerobic performance. Heart-rate recovery improved, indicating enhanced exercise tolerance. Random Forest identified phase angle, visceral fat, fat percentage, and fatigue index as the strongest predictors of injury risk. Conclusion 1. The body composition of professional basketball players was closely associated with anaerobic performance and recovery indices, with higher body fat percentage and central adiposity tending to be linked to reduced anaerobic capacity. 2. Reducing fat mass while preserving muscle mass did not adversely affect anaerobic performance and demonstrated potential improvements in performance efficiency, load tolerance, and recovery regulation. 3. A Random Forest Regression model based on body composition and anaerobic capacity indicators demonstrated a high level of accuracy in predicting performance decline and injury risk.

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.

Intrauterine devices (IUDs) are often considered a form of contraception by women of reproductive age because of their reversible, effective, safe, and convenient nature. However, its complications include bleeding, infection, displacement, and uterine perforation. Effective contraception can minimize the risk of unintended pregnancy, particularly for women who have additional health risks associated with unintended pregnancy. Intrauterine device (IUD) is considered to be a highly effective and reversible method of contraception (long-acting reversible contraceptives) that is suitable for most women, highly effective, affordable, and requires minimum patient compliance [1]. Despite being infrequent, perforation constitutes a significant complication associated with IUD insertion, with an estimated incidence of 0.8–2.2 per 1,000 insertions [2, 3]. Ultrasound is the preferred diagnostic modality in cases where partial embedding of the IUD is suspected. However, when the IUD extends near or beyond the uterine serosa, radiologists can more confidently diagnose embedding [4]. The patient is a 44-year-old woman with four children. She gave birth for the first time in 1997. A contraceptive device was inserted in 1999, and another was placed four months after her 2009 delivery. She does not recall the date when she had the latter device removed and has no record of having seen it. This case represents a rare instance of secondary bladder stone formation resulting from migration of an intrauterine device (T-shaped IUD) into the bladder. Rapid diagnostic methods, including ultrasonography, CT, and cystoscopy, along with endoscopic surgical intervention, proved to be the most effective approach for both diagnosis and treatment.

Background: Tick-borne encephalitis is human viral infection involving the nervous system and transmitted by the bite of infected tick. The TBE Virus is distributed in different geographical areas by three widespread subtypes of the virus: The Far East, Europe, and Siberia. The Far East type has a mortality rate was 30-35%, the European type has a mortality rate of 2.2%, and the Siberian type has a mortality rate of 6-8% (A.G. Pletnev, 1998) [2].
In recent years, human cases of tick-borne infections have been reported in 19 European countries and four Asian countries (Mongolia, China, Japan, and South Korea) [3].
Human cases of tick-borne encephalitis, tick-borne rickettsiosis, and tick-borne borreliosis have been registered in Mongolia since 2005. Deaths have been reported year by year [5].
During 2005 to 2021, tick-borne rickettsiosis (71.6%), tick-borne encephalitis (17.3%) and tick-borne borreliosis (52.9%) were confirmed by epidemiological, clinical and laboratory tests at the NCZD.
Tick-borne encephalitis was registered in 63 soums of 15 provinces and 9 districts of the capital city, of which 90% were infected with tick bites in Selenge and Bulgan provinces. The average mortality rate is 4.9% (14), of which 28.6% in Bulgan province and 2.7% in Selenge province.
Tick-borne encephalitis is the leading cause of death in Bugat soum of Bulgan province and more infected men about 40 years of age [7]. Purpose : Collect ticks from selected soums of the provinces, identify tick species, species composition, distribution, tick densities, pathogens of tick-borne diseases, conduct population surveys to assess the risk of tick-borne infections, and identify tick-borne infections. Material and Method: Ticks were collected by flag from birch trees in birch forests and meadows with biotope and overgrown berries, determined morphological analyze and molecular biological investigation for detecting tickborne pathogens.
Questionnaires were collected from selected soum residents according to a specially designed randomized epidemiological and clinical survey card, collected information and forms were submitted to soum hospitals with a history of tick bites (according to clinical criteria). Serological tests were performed to detect IgG-specific antibodies to the collected serum mites. Result and conclusion Collected 121 ticks (120 I. persulcatus and 1 D. nuttalli) and not wound egg, larvae, nymphs. By molecular biological investigation detected 3.5% of I.persulcatus from Khutag-Undur soum of Bulgan province, 3.5% of anaplasmosis, and 14.1% of I.persulcatus mites from Bugat soum. 1.5% borreliosis, 3.1% anaplasmosis.
Detected DNA of 100% tick-borne rickettsiosis from D.nutalli ticks and determined circulation of infection among tick in Bugat and Khutag-Undur soums of Bulgan province.
247 people were surveyed, 56 blood serum from cases. Detected Q fever, erysipelas, and anaplasmosis, tick-borne borreliosis 3 (5.4%), tick-borne rickettsiosis 26 (46.4%), Japanese encephalitis 3 (5.4%), tick-borne encephalitis tick-borne rickettsiosis 6 (13.0%), tick-borne rickettsiosis tick-borne borreliosis 1 (1.8%), tick’s rickettsiosis Japanese encephalitis 1 (1.8%), tick-borne encephalitis tick-borne borreliosis 1 (1.8%).
By investigation, vaccination (88%) and wearing long-sleeved shirts and pants (81%) were the most effective ways to prevent tick bites (81%) [15]. According to our research, the percent of population knowledge in Bulgan province was insufficient (40.9%) which there is a lack of information, training and advertisement among the population in the province.

Aflatoxins are the secondary metabolites of the fungi namely, Aspergillus flavus and A. parasiticus. They can colonize and contaminate grain before harvest or during storage. There are about twenty related secondary forms of aflatoxins, and subtypes B₁, B₂, G₁, G₂. These aflatoxins frequently contaminate the foods and feeds (Yu J et al, 2000, Imanaka BT et al, 2007). Aflatoxin B1, the most toxic, is a potent hepatocarcinogenic and genotoxigenic metabolites that have been classified as group I carcinogens by International Agency of Research on Cancer (International Agency for Research on cancer, 1993). Aflatoxin M1 is found in milk of lactating cows that have consumed feeds contaminated with aflatoxin B₁. Aflatoxin M₁ was originally classified as a Group 2B human carcinogen in 1993, but subsequent evidences of its cytotoxic, genotoxic and carcinogenic effects led to a new categorization of aflaoxin M1 as Group I (International Agency for Research on cancer, 2002). Aflatoxins can affect a wide range of commodities, including crops, cereals, oilseeds, spices, tree nuts, milk, meat, and dried fruit (Wilson DM et al, 1994, Bao L et al, 2010). Mongolia has been imported foods about 60 percent of food demands including wheat, flour, rice, milk, dairy products, peanuts and maize. This situation is required to study aflatoxin contamination in food in Mongolia. Epidemiological studies have found that dietary exposure to aflatoxin and chronic infection with hepatitis B, C virus are three major risk factors for HCC (Viviani et al. 1997; Hall et al. 2003). HCC as a result of chronic aflatoxin exposure has been well documented, presenting most often in persons with chronic hepatitis B virus (HBV) infection (Wild and Gong, 2010). The risk of liver cancer in individuals exposed to chronic HBV infection and aflatoxin is up to 30 times greater than the risk in individuals exposed to aflatoxin (Groopman et al., 2008). According to the WHO, the national liver cancer incidence rates was 54.1 per 100.000 population, the prevalence of HBV and HCV infection in 11.8%, 15.6% were respectively (J.Abarsanaa, 2012). This situation is a serous public health problem in Mongolia. Thus, we aimed to carry out the monitoring surveillance survey on the aflatoxin contamination level in some food.

OBJECTIVESThe aim of this study was to determine the prevalence of Echinococcus multilocularis environmental contamination in an urban fringe-the Nopporo forest park of Sapporo city, Hokkaido, Japan. A secondary aim was to determine possible transmission risks areas by associating percentage occurrence of E. multilocularis-positive faeces with the different land-use classes.

METHODSWild fox faeces collected from the environment were examined by intravital methods, such as the taeniid egg sucrose floatation technique, E. multilocularis coproantigen enzyme-linked immunosorbent analysis and DNA test of taeniid eggs by PCR. Geospatial maps produced by the Global Positioning System and Landsat data were analysed using geographic information system software to determine the association between percentage occurrences of E. multilocularis-positive fox faeces and land-use classes.

RESULTSOur findings showed high prevalence rates in both E. multilocularis egg and coproantigen-positive faeces (16 and 49%, respectively) in the investigated urban fringe forest park. Data revealed that percentage occurrence of E. multilocularis-positive fox faeces was associated with land-use classes, such as forest and open field (P < 0.05).

CONCLUSIONSWe conclude that Nopporo forest park in the urban fringe of Sapporo city, Hokkaido is a reservoir with a high prevalence of zoonotic infective agents for alveolar echinococcosis. Our findings suggest that interface habitats between forests or woodlands and open fields are indispensable for continued maintenance of the life-cycle of E. multilocularis and, as such, constitute high risk areas for echinococcosis transmission.
