Bacterial Heavy Metal Resistance in Contaminated Soil.

Soil heavy metal contamination poses a significant global threat to both environmental and human health. The accumulation of heavy metals in the Earth's crust, driven by urbanization, industrialization, agricultural practices, improper waste disposal, and mining, triggers harmful ecological cascades. Microorganisms, particularly bacteria, play a vital role in the decomposition and detoxification of these contaminants.

Effects of monitoring dietary biomarkers and providing vegetable juice on metabolic syndrome components in adults with an overweight or obese body mass index in Ulaanbaatar: a randomized controlled trial.

Background: Mongolian people have traditionally had poor vegetable intake habits, which is a cause of increasing prevalence of metabolic syndrome. Monitoring vegetable intake through the dietary biomarkers such as skin carotenoid level, and urinary sodium-to-potassium (Na/K) ratio (represents intake status of salt and vegetable), has been recently suggested to be useful to improve dietary habits. Vegetable juices are an easy way to consume vegetable-derived ingredients.

Sex differences in the prevalence of metabolic syndrome and associated factors in the general population of Mongolia: A nationwide study.

The prevalence and factors associated with metabolic syndrome (MetS) between men and women in Mongolia were compared using secondary data from the STEPwise approach to non-communicable disease risk factor surveillance conducted in 2019. In total, 5,695 participants (2,577 males and 3,118 females) aged 18-69 years old were enrolled in the study. The prevalence of MetS was 37.

Acceptance of Self-Sampling and Knowledge about Human Papillomavirus among Women in Mongolia.

Background: Mongolia faces a significant burden of cervical cancer, with the highest prevalence of Human Papillomavirus (HPV) in the region. Cervical cancer ranks as the third most common cancer among women in the country. This study aimed to assess the acceptance of self-sampling among young women in Mongolia and evaluate their knowledge regarding HPV and cervical cancer.

3-Dimentional printing of polysaccharides for water-treatment: A review.

Biological polysaccharides such as cellulose, chitin, chitosan, sodium alginate, etc., serve as excellent substrates for 3D printing due to their inherent advantages of biocompatibility, biodegradability, non-toxicity, and absence of secondary pollution. In this review we comprehensively overviewed the principles and processes involved in 3D printing of polysaccharides.

Immunogenicity, safety, and reactogenicity of a half- versus full-dose BNT162b2 (Pfizer-BioNTech) booster following a two-dose ChAdOx1 nCoV-19, BBIBP-CorV, or Gam-COVID-Vac priming schedule in Mongolia: a randomised, controlled, non-inferiority trial.

Background: COVID-19 vaccine booster doses restore vaccine effectiveness lost from waning immunity and emerging variants. Fractional dosing may improve COVID-19 booster acceptability and uptake and will reduce the per-dose cost of COVID-19 booster programmes. We sought to quantify the immunogenicity, reactogenicity, and safety of a half-dose BNT162b2 (Pfizer-BioNTech) booster relative to the standard formulation.

A single dose of quadrivalent human papillomavirus (HPV) vaccine is immunogenic and reduces HPV detection rates in young women in Mongolia, six years after vaccination.

Background: Emerging observational evidence suggests a single-dose of human papillomavirus (HPV) vaccine may be protective against vaccine-targeted HPV infection and associated cervical dysplasia. We aimed to demonstrate whether a single dose of quadrivalent HPV (4vHPV) vaccine was immunogenic and reduced HPV detection rates in young women in Mongolia. We also assessed knowledge and attitudes regarding HPV and the HPV vaccine.

HPV genoprevalence and HPV knowledge in young women in Mongolia, five years following a pilot 4vHPV vaccination campaign.

Background: In a 2012 pilot, 9111 Mongolian girls aged 11-17 years received three doses of the quadrivalent (4vHPV) vaccine, Gardasil. This is the first study to measure early vaccine effectiveness and assess knowledge and attitudes of young women in Mongolia in relation to the human papillomavirus (HPV), the vaccine and cervical cancer.

Methods: A cohort of women vaccinated in 2012 (n = 726) and an unvaccinated cohort (n = 790) provided self-administered vaginal swabs for detection of high-risk HPV genotypes 16, 18/45, 31, 33, 35, 39, 51, 52, 56, 58, 59, 66, 68 five years following vaccination.

A new cinnamoylphenethylamine derivative from a Mongolian Allium species, Allium carolinianum.

A new cinnamoylphenethylamine derivative, compound 1, was isolated as the main HPLC peak after partitioning the methanol extract of bulbs of a Mongolian onion species, Allium carolinianum DC. The chemical structure of this substance was determined by spectroscopic analysis including MS, and 1D and 2D NMR. Compound 1 showed weak cytotoxic activity in the murine leukemia cell line P388.

Mercury exposure in female artisanal small-scale gold miners (ASGM) in Mongolia: An analysis of human biomonitoring (HBM) data from 2008.

Background: Many poor in developing countries have turned to artisanal small-scale gold mining (ASGM) in an attempt to improve their situation. However, the mercury used to extract gold from ore is discharged in vaporized form into the environment, where it poses a hazard for human health.

Methods: As part of an environmental epidemiological study in Mongolia-to evaluate the burden of environmental mercury contamination-urine, blood and hair samples were collected from residents of areas with or without mercury contamination.

Antitumor activities of O-sulfonated derivatives of (1-->3)-alpha-D-glucan from different Lentinus edodes.

Four water-insoluble (1-->3)-alpha-D-glucans, coded L-II1, L-II2, L-II3 and L-II4, with different molecular weights were isolated from four kinds of fruiting bodies of Lentinus Edodes. The four alpha-D-glucans were O-sulfonated to obtain derivatives (SL-II) having degrees of substitution (DS) from 0.9 to 2.
