ABSTRACT
OBJECTIVE: High precise evaluation of the nasopalatine canal morphology is essential to perform detailed diagnosis and treatment plans in implantology and the orthodontic field. We aimed to study morphometric analysis measurements of the nasopalatine canal. MATERIAL AND METHODS: In this cross-sectional study, maxillary CBCT images from 125 patients were evaluated in the Maxillofacial Radiology department between 2014-2021. Sagittal views were assessed to determine nasopalatine canal morphology and dimensions. The difference in canal diameter and length between genders was evaluated using an One Way ANOVA test. RESULTS: There was no significant sex difference among all 125 cases in nasopalatine canal diameter, length, anterior bone plate width. The average length of the nasopalatine canal was 16.49±2.8 mm in male, 16.20±2.9 mm in female, incisive foramen diameter in the sagittal plane was 4.04±0.9 mm in male, 4.02±0.9 mm in female, nasopalatine foramen diameter was 4.63±1.4 mm in male, 4.75±1.2 mm in female. The width of the bone anterior to the canal was 5.89±1.4 mm in males, 5.69±1 mm in females. CONCLUSION: 16-48 aged Mongolian average length of the nasopalatine canal was 16.3 mm, and average incisive foramen width was 4.08 mm, the average width of the bone anterior to the canal was 5.76 mm. Anterior retraction treatment for upper incisor root can be done safely without root resorption around 5.5 mm in the premaxillary alveolar bone.

Introduction@#Khuumii (throat singing) is a unique form of art derived from the nomadic population of Central Asia, producing two or more “simultaneous” sounds and melodies through the organ of speech. @*Material and Methods@#The aim of the study is to identify the anatomical structures involved in the formation of khuumii and the features and patterns of their functions and compare each type of khuumii as performed by Mongolian people. A total of 60 participants aged 18-60 years (54 men and 6 women) were selected by non-random sampling method using cross-sectional study. Statistical analysis was performed using SPSS 23 software using questionnaires, X-ray, endoscopy, sound research method, and general blood tests. @*Results@#90.7% of the khuumii singers were male and 9.3% were female. The average height of the participants was 172.91±0.93 cm (arithmetic mean and mean error), average body weight was 77.53±2.46 kg, and body mass index was 25.93±5.31 respectively. Heart rate was 92.19±20.71 per minute prior to khuumii while 133.19±19.09 after performing khuumii and 85.81-98.56 at 95% confidence interval. In terms of ethnicity (ethnographically), the Khalkh were the largest ethnic group (72.1%), followed by Bayad, Buryatia, Darkhad, Torguud, and Oirat (2.3%), respectively. 60.5% of the participants were professional khuumii singers who graduated from relevant universities and colleges. The process of Khuumii was recorded by X-ray examination, and laryngeal endoscopy evaluated the movement of true and false vocal chords, interstitial volume, movements of epiglottis and arytenoid cartilage, and mucosa. Khuumii increases the workload of the cardiovascular system by 70-80%. Furthermore, the sound frequency is 2-4 times higher than that of normal speech, and sound volume is 0.5-1 times higher. 95.3% of throat singers did not have a sore throat, 88.4% did not experience heavy breathing, and 74.1% had no hoarseness. During the formation of khuumii sound, thoracic cavity, diaphragm, and lungs regulate the intensity of the air reaching the vocal folds, exert pressure on the airways and vibrate the sound waves through air flows passing through the larynx and vocal folds. Mouth-nose cavity as well as pharynx are responsible for echoing the sound.@*Conclusion@#It is appropriate to divide khuumii into two main types according to structural and functional changes in the organs involved; shakhaa and kharkhiraa. Khuumii, the “Human music” originating from the people of Altai Khangai basin by imitating the sounds of nature with their own voice in ancient times, spread all over the world from Mongolia and it is proposed to classify khuumii into two main types of shakhaa and kharkhiraa in terms of structural involvement and functionality.
ABSTRACT
Oriental medicine, are described in detail about the human body association between systemic and musculoskeletal system, the location of the organs and critical points. Critical point or biological active point in the human body has a total of 302, classified about lives and impact is most dangerous, more dangerous and dangerous. These ascertaining theoretical and usage is important. Our aim was to study in limbs of the body composition and perceived status in the critical point.Total 62 most healthy people obtained to the research from this 31 people were male, 31 people were female and 18-28 ages. We used algometry, anthropometry and VAS. Upper and lower limbs of the body composition and perceived status in the critical point compared with body constitution.Statistical analyses were conducted in SPSS (PASW) Version 17.0.The mean age were had male 18.47, female 23.42 obtained to the research. “Wind-bile”, “windphlegm” body constitution people were 22.58%, “phlegm-bile” body constitution people were 8.06% and “wind-bile-phlegm” body constitution people not available. A high significant decrease, high correlation in “phlegm-bile” body constitution people were the most high measured in 9 point, “bilewind” body constitution people were lowest measured in 8 point by anthropometry.Comparing results by anthropometric indication, algometry tools, VAS methods is dependent to the positive or reserve.

ABSTRACT
Background: The cardiovascular disease especially coronary artery disease is the leading cause of mortality in worldwide. There is lack of research study which evaluated stenosis of coronary atherosclerosis. It is known that coronary stenosis is highly connected to the levels of biomarkers. Coronary atherosclerosis correlated with endothelin receptor type A (EDNRA) levels in a group of patients suspected of having coronary artery disease. Objective: The goal of this study was to evaluate the relation between the coronary atherosclerosis and levels of EDNRA Methods: A total of 311 participants were involved in this study. A case-control study was used in the study. The baselines data were collected from the department of Angiography at the National Third Central Hospital and National lilood Transfusion and Research center. We have determined the degree of coronary atherosclerosis using the Angiography machine and Elisa were used for detecting the blood endothelin levels in all groups. Results: 98 participants were diagnosed with stenosis and occlusion. The blood endothelin levels were estimated to 6.32±0.64 pg/ml which refer to () degree of coronary stenosis, the first degree of stenosis of coronary atherosclerosis is estimated to 5.56±0.22pg/ml, the second degree of stenosis of coronary atherosclerosis is estimated to 5.42J0.34 pg/ml, the third degree of stenosis of coronary atherosclerosis is estimated to 5.87 H). 13 pg/ml, the fourth degree of stenosis of coronary atherosclerosis is I'SlilllSltll lo 5.69±0.09 pg/ml, it was estimated to 5.88±0.13 pg/ml in control groups. Level of EDNRA (occupying one segment of coronary artery) was estimated to 5.77±0.08 pg/ml. two segment involvement was estimated to 5.72±0.16 pg/ml, three segment involvement 5.73±0.19 pg/ml. four segments involvement 5.50±0.25 pg/ml, respectively. Conclusion: The blood endothelin level and coronary artery stenosis were not correlated statistically significant in control group of the study. However, blood endothelin levels were increased in patients who tend to experience the coronary artery stenosis.

ABSTRACT
Knowledge of morphometric quantities of coronary arteries in infants is an increasingly vital component in managing congenital and acquired heart disease. Because of considerable heterogeneity of coronary vasculature, what is considered atypical and aberrant or insignificant anatomy is often unclear. The purpose of our present study is to define normal infant anatomy. This was done by focusing on the segment analysis of coronary arteries in infants. Segment analysis was used to define an accurate definition of the length and diameter of the coronary network. The lengths, widths, and numbers of collateral branches of the coronary arteries were measured. The coronary vessels of 40 infant hearts were visualised postmortem by injection of the coronary arteries with X-ray opaque dye for the imaging study. Also, black ink cast and silver impregnation specimens were studied. The longest segment of the circumflex branches of left coronary arteries was the second; the lengths were 9066.6 ± ± 1828 µm. The length of I, III, and IV were 7366 ± 378.7 µm, 7536.6 ± ± 1533.8 µm, 4476.6 ± 690.9 µm, respectively. The lengths of the circumflex branch of the coronary artery were longer than that of the others; it is joined with the anterior interventricular branch of the coronary artery in the dorsal wall of the left ventricle. Rates of branching and ramification were low, and the number of lateral branches was low.

Knowledge of the morphometric quantities of the coronary arteries in neonates is an increasingly vital component in the management of congenital and acquired heart disease. Because of the considerable heterogeneity of coronary vasculature, what is considered atypical and aberrant or insignificant anatomy is often unclear. The purpose of our present study is to define the normal anatomy of neonates. This was done by focusing on segment analysis of the coronary arteries, which was used to obtain accurate definitions of the length and diameter of the coronary network. The lengths, widths and numbers of collateral branches of the coronary arteries of neonates were measured. The coronary vessels of 50 neonate hearts were visualised post mortem by injection of the coronary arteries with opaque X-ray dye for the imaging study. Black ink cast and silver impregnation specimens were also studied. The longest segment of the circumflex branches of the left coronary arteries was the first, the lengths measuring 7188.5 +/- 839.6 microm and the diameters 850 +/- 90.8 mum. The lengths of segments II, III and IV were 5780 +/- 1182.7 microm, 5397.5 +/- 2070.2 microm and 6932.8 +/- 2236.5 microm and the diameters were 680 +/- 90.8 microm, 510 +/- 90.8 microm and 408 +/- 77.58 microm respectively. The longest segment of the anterior interventricular branches of the left coronary arteries was the first, with lengths of 10151.4 +/- 1298.6 microm and diameters of 1141.9 +/- 82.1 microm. The lengths of segments II, III and IV were 8208.5 +/- 1222.3 microm, 3278.5 +/- 602.4 microm and 5370 +/- 1657.6 mum and the diameters were 971 +/- 82.1 microm, 801.42 +/- 82.1 microm and 631.4 +/- 82.1 microm respectively. The lateral branches were increased in number in the fourth segment. Its diameters ranged from 157.8 +/- 31.7 microm to 655.7 +/- 99.7 microm. The main branch of the right coronary artery was short at the base of the heart. In the newborn the lateral branches of the right coronary artery were short, scattered and curved. Analysis of the data suggests a new anatomical system for classifying the vasculature of the coronary arteries in neonates.
