Background. There are varieties of supports from Mongolian government and health organizations to people with epilepsy. However, epileptics are often socially discriminated due to the negative public attitudes, misconceptions, false beliefs and wrong decisions. Because of this they miss out their right to study or work. Under the aim of providing right information and knowledge about epilepsy to public, carrying out continuous health educational trainings and studies among population is very important to reduce negative attitude towards epilepsy, to prevent from epilepsy stigma and to improve patients’ quality of life.Goal. The objective of this study was to assess the understanding, knowledge and attitude towards epilepsy among population in Ulaanbaatar and to determine some influencing factors.Methods. Questionnaire was carried out within randomly selected 700 people from 6 districts in Ulaanbaatar city.Results. Participants’ age range was from 16 to 64 years and average age was 36.0 (SD 9.34). 64.1% (449) participants out of all had some understanding and knowledge about epilepsy while they possess high school and university educational degree. 42.2% (295) participants had some knowledge about causes of epilepsy, how to react and how to give a first aid for epilepsy patients. However, 57.8% (405) participant out of all involved in the study had not enough knowledge about epilepsy. 29.7% (208) participant had a positive attitude towards epilepsy.ConclusionPersonal age, educational level, information accessed and interaction with people with epilepsy influences to the knowledge about epilepsy.

BACKGROUNDScaffolds with the capacity to deliver signaling molecules are attractive for bone regeneration. Here, we developed bioactive siloxane–gelatin hybrid scaffolds via a sol gel process containing stromal derived factor-1 (SDF-1) to recruit osteoprogenitor/stem cells. METHODSThe process was undertaken under room temperature aqueous conditions, which enabled therapeutic molecules to be effectively incorporated. After the sol-gel reaction and lyophilization process, well crosslinked hybrid scaffolds were obtained with porosities of 80–90%.RESULTSDynamic mechanical analysis of the hybrid scaffolds showed significant improvement in storage modulus values (from 10 to 110 kPa) with increasing siloxane content. Target molecule SDF-1 was loaded and released from the scaffolds, and the effects on the homing of mesenchymal stem cell were studied.CONCLUSIONSResults demonstrated significant enhancement in the migration of cells to the SDF-1 loaded scaffolds. Taken together, the developed hybrid scaffolds areconsidered to be useful in loading and delivering signaling molecules such as SDF-1 to recruit osteoprogenitor /mesenchymal stem cells in the bone regeneration process.

Background:
The lower socioeconomic status and long distance to eye care facility of the rural
dwellers in many communities in developing countries accounts for the increase in the number
of preventable and avoidable causes of blindness. It is widely believed that the best option to
reduce blindness and visual impairment in these communities is to bring eye care services to their
doorsteps in the form of outreach programs.
Aims:
To assess the pattern of eye diseases presenting at a free eye outreach in a rural community
of Mongolia.
Methods:
A retrospective, descriptive study was carried out on the findings of 2-day outreach
programs at Medical Center of Ulziit village, Arkhangai province of Mongolia. Patient history
including sociodemographic data and comprehensive eye examination were done in the study
group.
Results:
The most common ocular disorder in the study group was external eye diseases including
conjunctivitis. There were more females seen at the free eye outreach clinic and majority of
participants were 45-59 years old.
Conclusion
In sparsely densely countries like Mongolia, outreach screening programs for ocular
morbidity is crucial to decrease low vision and blindness.

Backround:
The university period is a unique phase in students’ lives, often marked by independent living, changes in
lifestyle, diet, sleep patterns, increased psychological stress, and the development of unhealthy behaviors. Among students, particularly those studying in the medical field, research on dietary habits and influencing factors is scarce in our
country, which serves as the rationale for this study.
Aim:
The aim of this study is to investigate the dietary habits of medical students and the factors influencing them, including sleep, impulsivity, depression, anxiety, and stress.
Materials and Methods:
A cross-sectional study was conducted among 358 students from years 1 to 6 across 7 schools of
the Mongolian National University of Medical Sciences (MNUMS). Data were collected using internationally standardized and validated questionnaires, including the Three-Factor Eating Questionnaire Revised-18 (TFEQ-R18), the Short
UPPS-P Impulsive Behavior Scale-20 (SUPPS-P-20), the Depression, Anxiety, and Stress Scale-21 (DASS-21), and the
Pittsburgh Sleep Quality Index (PSQI). Statistical analysis was performed using SPSS 25.0.
Results:
In terms of eating behavior, uncontrolled eating (UE) and cognitive restraint (CR) were similar between male
and female students, while emotional eating (EE) was more prevalent among male students. Students’ eating behaviors
were associated with body mass index (BMI). As BMI increased, levels of depression, anxiety, and stress also tended to
rise. Sensation-seeking and positive urgency were higher among female students. Overall, 83.5% of students had poor
sleep quality, which contributed to increased depression, anxiety, stress, and impulsivity. Psychological burden and impulsivity were independent of the field of study but decreased as students progressed through their academic years, while
sleep quality improved.
Conclusion
The dietary habits of medical students were similar across genders but varied by academic year and field
of study. Poor sleep quality, observed in 83.5% of students, was associated with increased depression, anxiety, stress,
and impulsivity. Psychological burden and impulsivity were unrelated to the field of study but decreased with advancing
academic years, alongside improved sleep quality. As BMI increased, cognitive restraint in eating behaviors decreased.

Calcium salt composite/calcite or spar is one of traditionally used therapeutic material for
hard tissue repair and regeneration due to its abundant calcium content. There are several
types of calcite (fluorspar or calcite fluoride, cobaltoan calcite, etc) exist in the nature and their
therapeutic effects are different depending on their basic properties. For instance, calcium
carbonate based calcite used to treat damaged hard tissue in the traditional medicine. Here,
we would like to investigate characterizations of three different types of calcites gathered from
the nature. For this purpose, collected calcium salt composites ( calcite, fluorspar, feldspar )
were examined their surface properties, morphology and size by the scanning electron microscopy. Energy-dispersive X-ray spectroscopy was used to determine their elemental analysis and X-ray diffraction was carried out to characterize their crystallinity structure. Based on the calcium contents, calcium carbonate-based calcite was selected to form nano-sized
calcite and study their toxicity by using mesenchymal stem cell. Throughout this study, we
identified properties of three different calcites and successfully reduced size in nanoscale
which helps to use in the future treatment of osteoporosis or to stimulate osteogenesis.
