  • The growing problem of obesity is associated with numerous medical conditions. Several studies have reported that activation of thyroid hormone receptor beta $(THR{\beta})$ is involved in lipid metabolism and thermogenesis. To identify the relationship between the $THR{\beta}$ gene and obesity, we genotyped eighty two single nucleotide polymorphisms (SNPs) in the gene using the Affymetrix array chip in 209 overweight/obese and 155 normal subjects in Korean population. Of the eighty two polymorphisms, the seven SNPs exhibited a significant association with overweight/obesity in three alternative models (codominant, dominant, and recessive models; P<0.05 after adjusting for age and sex) were rs826221 (+267878 T>C), rs4858604 (+186399 A>G), rs1158265 (+200152 T>C), rs1868575 (+206031 G>A), rs1700939 (+238467 T>A), rs1505301 (+241933 T>C), and rs1924768 (+126491 T>C). During haplotype analysis using HapAnalyzer software, 2 haplotypes (block 13: TTAT; block 15: CTGC) containing significant polymorphisms (rs1700939 +238467 T>A and rs4858604 +186399 A>G) were detected to be significantly different. The results suggest that the $THR{\beta}$ gene may be associated with overweight/obesity in Korean population.

  • Dynamic X-ray (DXR) is a functional imaging technique that uses sequential images obtained by a flat-panel detector (FPD). This article aims to describe the mechanism of DXR and the analysis methods used as well as review the clinical evidence for its use. DXR analyzes dynamic changes on the basis of X-ray translucency and can be used for analysis of diaphragmatic kinetics, ventilation, and lung perfusion. It offers many advantages such as a high temporal resolution and flexibility in body positioning. Many clinical studies have reported the feasibility of DXR and its characteristic findings in pulmonary diseases. DXR may serve as an alternative to pulmonary function tests in patients requiring contact inhibition, including patients with suspected or confirmed coronavirus disease 2019 or other infectious diseases. Thus, DXR has a great potential to play an important role in the clinical setting. Further investigations are needed to utilize DXR more effectively and to establish it as a valuable diagnostic tool.

  • Cleidocranial dysplasia is rare inherited skeletal dysplasia. It was first reported by Martin in 1765. Subsequently, Marie and Sainton independently documented the criteria of the disease. Cleidocranial dysplasia is a bone disorder caused by a defect in the CBFA1 gene of chromosome 6p21. This gene guides osteoblastic differentiation and appropriate bone formation. Patient with cleidocranial dysplasia has maxillary deficiency, high and narrow palate, prolonged retention of primary teeth, unerupted permanent teeth and supernumerary teeth. Therapeutic options in these patients include of autotransplantation of selected impacted teeth, forced eruption of permanent teeth, full denture, overdenture and implant-supported prosthesis. We report a patient with cleidocranial dysplasia. This patient was treated with implant supported bar overdenture. Despite of gene defect that affects osteoblastic activity, bone remodeling and osseointegration occurred in our patient. So, we report this case with review of literature.

  • Background and Objectives: A nerve conduction study (NCS) has been known as a useful method to evaluate the therapeutic effect of operation in carpal tunnel syndrome (CTS). To evaluate the temporal relationship between symptomatic and electrophysiological improvement, we compared the preoperative symptoms and electrophysiological results with postoperative those. Methods: We analyzed the NCS changes before and after minimal release of carpal tunnel in 26 patients (34 hands) with CTS. The time of postoperative symptomatic changes, postoperative electrophysiological changes and temporal relationship between symptomatic and electrophysiological changes were evaluated. Results: The mean age was $49{\pm}13$ years. The proportion of males to female was 8 and 92 percent. The median interval days between date of operation and those of postoperative NCS was 28.5 days. Postoperative symptoms improved in 17 hands, slightly improved in 13 hands, and have not changed in 4 hands. Electrophysiological improvements after operation were observed in 26 hands, and mostly appeared within 2 months. Symptomatic relief accompanied with electrophysiological improvement reported in 13 hands (50%). Moreover, the four hands with symptom, not relieved by decompression, showed electrophysiological improvement. Conclusions: In this study, electrophysiological improvement was in consistency with symptomatic relief to some extent, but we got the result of disagreement between electrophysiological and symptomatic improvement.

  • To investigate the possible mechanisms of high-altitude native animals in adapting to high altitude, we cloned hemoglobin alpha-chain (alpha-chain Hb) gene from Pantholops hodgsonii, an animal species that indigenously lives at elevations of 3700-5500 m on the Qinghai-Tibetan plateau. Using reverse transcription polymerase chain reaction (RT-PCR) technique, the alpha-chain Hb gene was amplified from total RNA in the liver of the Pantholops hodgsonii. TA cloning technique was used and the PCR product was cloned into pGEM-T vector. The DNA sequence of the gene was highly homologous with sheep (99.1%), goat (98.6%), cattle (95.6%) and human (86.5%). The alpha-chain Hb gene encoded a 142-amino acid protein that could be identified with the homology of alpha-chain Hb protein in sheep (98%), goat (96%), cattle (91%) and human (87%). However, 18 alternations were detected when compared with the alpha-chain Hb gene in human, and 2 in sheep. Moreover, the alterations of a117 GluAsp and $\alpha$132 AsnSer in important regions were noted in human and sheep, respectively. Phylogenetic analysis suggested that the structure of alpha-chain Hb was highly similar to that in sheep. This study provided essential information for elucidating the possible roles of hemoglobin in adapting to extremely high altitude in Pantholops hodgsonii.

  • This study aimed to identify curriculum gaps and a pilot study to provide the programs for selection during clerkship. Over the course of a clerkship, students analyze the current level and the needs level of TLO (terminal learning objectives) based on the book "Learning outcome of basic medical education: Scientific concept and principle-centered." We conducted a needs assessment utilizing a t-test, Borich Needs Assessment, and the Locus for Focus model. In the investigation of the needs level, the levels of the musculoskeletal and respiratory systems were relatively high and in the investigation of the current level, the levels of the digestive and musculoskeletal systems were relatively high. This study is expected to contribute to reasonable decision-making by utilizing various methods of analysis and providing in-depth results of needs analysis in designing clerkship curriculum.
