This study was performed to examine the combined effects of L-carnitine and isoflavone supplementation on weight reduction and body fat distribution in overweight women. Overweight/obese women (body mass index > $23kg/m^2$) who were not diagnosed any type of diseases were included in this study and sixty subjects ($41.1{\pm}1.5$ years, $25.9{\pm}0.3kg/m^2)$ were randomly assigned to a placebo (n=30) or a supplement group (n=30, L-carnitine 300 mg+isoflavone 40 mg/day). We measured anthropometric parameters, abdominal fat distribution by computerizd tomography and blood components before and after the 12 week intervention period. After the 12 weeks of supplementation, subjects in L-carnitine and isoflavone supplement group showed a significant reduction of body weight (p < 0.001), body fat % (p < 0.05), and waist to hip ratio (p < 0.01) whereas placebo group did not show any changes. In a CT-scanned results, total fat area at L4 level was significantly reduced by 8.1% (p < 0.01) with the reduction of visceral fat area (-11.1%, p < 0.001) and subcutaneous fat area (-7.0%, p < 0.05) in the supplement group. The supplementation of L-carnitine and isoflavone showed the significant improvement of HDL-C (p < 0.01) and apoB (p < 0.05) concentrations, however, change values in those markers were not significant compared with those of the placebo group. In addition, a significant increase of adiponectin level (p<0.001) was observed in the supplement group after the intervention. The result of present study demonstrated that supplementation of 300 mg L-carnitine and 40 mg isoflavone per day fur 12 weeks can give beneficial effects on weight reduction and visceral fat accumulation. These potential antiobesity supplement can produce more favorable effects when combined with lifestyle modification.

The aim of this study was to determine the effect of maturity stage on the nutritive value of wild mustard straw in terms of chemical composition, in situ, in vitro dry matter degradability and calculated ME. The nutritive values of wild mustard, Sinapsis arvensis hays harvested at three stages were evaluated by chemical composition, in vitro gas production and in situ dry matter degradation methods. Gas production or dry matter (DM) degradation were determined at 0, 3, 6, 12, 24, 48, 72 and 96 h and their kinetics were described using the equation p = a+b(1-e$^{-ct}$). Maturity had a significant effect on both the chemical composition and degradability of wild mustard. Neutral detergent fibre (NDF) and acid detergent fibre (ADF) (p<0.001) increased with increasing maturity whereas the crude protein (CP) (p<0.001) decreased. The gas produced after 96 h incubation ranged between 64.7 and 81.5 ml per 0.200 g of dry matter. The gas production (ml) at all incubation times and estimated parameters decreased with increasing maturity of wild mustard. The gas production at all incubation times and estimated parameters (a, b (a+b), metabolizable energy (ME) and organic matter digestibility (OMD)) were negatively correlated with NDF and ADF. The DM disappearance after 96 h incubation ranged between 50.8 and 76.1%. The in situ DM disappearance at all incubation times and estimated parameters decreased with increasing maturity of wild mustard. The in situ dry matter disappearance at all incubation times and some estimated parameters (c, a, b and effective dry matter degradability (EDMD)) were negatively correlated with NDF and ADF but positively correlated with CP. The nutritive value of wild mustard continually changed as it matured. Wild mustard, harvested at the proper stage of maturity offers considerable potential as a high quality forage for ruminants during the winter feeding period. The present study showed that if higher quality forage is an objective, wild mustard should be harvested at the early flowering stage.

Background: p53 alterations have been implicated in the development of many cancers, such as gastric cancer, but there is no evidence of p53 intron alterations in gastritis lesions. The aim of this study was to investigate the p53 intron alterations in gastritis along with p53 and mismatch repair protein expression and microsatellite status. Materials and Methods: PCR-sequencing was conducted for introns 2-7 on DNA extracted from 97 paired samples of gastritis lesions and normal adjacent tissue. Abnormal accumulation of p53 and mismatch repair proteins was investigated using immunohistochemistry. In addition, microsatellite status was evaluated with reference to five mononucleotide markers. Results: Gastritis cases included 41 males and 56 females in the age range of 15-83 years, 87.6% being H.pylori positive. IVS2+38, IVS3ins16 and IVS7+72 were the most polymorphic sites. Their minor allele frequency values were as follows: 0.38, 0.21 and 0.06, respectively. Samples with GG genotype at IVS2+38 and CT at IVS7+72 had no insertion. Moreover, most of the stable samples (91.9 %) had a G allele at IVS2+38. All of the samples were IHC negative for p53 protein, microsatellite stable and expressed mismatch repair proteins. p53 alterations were prominent in the H. Pylori+ group, but without statistical significance. Conclusions: According to our results, some p53 polymorphisms such as IVS2+38, IVS3ins16 and IVS7+72, because of their correlations together or with microsatellite status may contribute to gastritis development. However, so far effects on p53 expression and function remain unclear. Therefore, a comprehensive survey is needed to delineate their biological significance.

Brachyspira (B.) hyodysenteriae is a causative agent of swine dysentery that is responsible for death and economic losses in the pig industry. It is imperative that clinical samples be delivered fresh for accurate diagnosis. The viability and DNA detection of B. hyodysenteriae using lab-made (phosphate buffered saline and modified tryptic soy broth) or commercial transport media (C, D, and E) were compared by culturing and real-time PCR at $4^{\circ}C$ or room temperature (RT), respectively. B. hyodysenteriae grown in D (Anaerobe Systems, USA) and E (Starplex Scientific, Canada) media was viable for 4 days at $4^{\circ}C$ and RT. However, B. hyodysenteriae in A, B, and C (culture swab; BD Biosciences, USA) media were not recovered after 2 days at RT. Ct values for real-time PCR at $4^{\circ}C$ and RT ranged from $27.2{\pm}2.1$ (C) to $29.6{\pm}0.5$ (B), and $28.0{\pm}0.9$ (E) to $30.2{\pm}1.5$ (B), respectively. Considering the field conditions, it is important that transport media is used for specimen isolation and PCR to obtain an accurate diagnosis of swine dysentery.

Objective: Fluorine-18-fluorodeoxyglucose positron emission tomography (18F-FDG-PET) is a new technique for identifying different malignant tumors using different uptake values between tumor cells and normal tissues. Here we assessed the diagnostic accuracy of 18F-FDG-PET in patients with testicular cancer by pooling data of existing trials in a meta-analysis. Methods: PubMed/MEDLINE, Embase and Cochrane Central Trials databases were searched and studies published in English relating to the diagnostic value of FDG-PET for testicular cancer were collected. The summary receiver operating characteristic (SROC) curve was used to examine the FDG-PET accuracy. Results: A total of 16 studies which included 957 examinations in 807 patients (median age, 31.1 years) were analyzed. A meta-analysis was performed to combine the sensitivity and specificity and their 95% confidence intervals (CIs), from diagnostic odds ratio (DOR), positive likelihood ratios (PLR), negative likelihood ratio (NLR). SROC were derived to demonstrate the diagnostic accuracy of FDG-PET for testicular cancer. The pooled sensitivity and specificity were 0.75 (95% confidence interval (CI), 0.70-0.80) and 0.87 (95% CI, 0.84-0.89), respectively. The pooled DOR was 35.6 (95% CI, 12.9-98.3). The area under the curve (AUC) was 0.88. The pooled PLR and pooled NLR were 7.80 (95% CI, 3.73-16.3) and 0.31 (95% CI, 0.23-0.43), respectively. Conclusion: In patients with testicular cancer, 18F-FDG-PET demonstrated a high SROC area, and could be a potentially useful tool if combined with other imaging methods such as MRI and CT. Nevertheless, the literature focusing on the use of 18F-FDG-PET in this setting still remains limited.

Purpose: A tension pneumothorax is a fatal condition that requires immediate intervention. Although a definitive treatment for a tension pneumothorax is a tube thoracostomy, needle decompression can provide temporary relief, that is lifesaving. The traditional procedure for needle decompression involves inserting a needle or catheter at the second intercostal space, the midclavicular line. Recent evidence suggests that the commonly used catheters do not have sufficiently penetrate the chest wall. There are also claims that a lateral approach to needle decompression is easier and safer than the traditional anterior approach. The purpose of this study is to evaluate the optimal approach for needle decompression for the Korean population by measuring chest wall thicknesses at the points used for both the anterior and the lateral approaches. Methods: The chest wall thickness (CWT) of trauma victims who visited the Emergency Center of Pusan National University Hospital was measured by computed tomography (CT) images. The CWT was measured at the points used for the anterior and the lateral methods and was compared with the length of commonly used catheters, which is 45 mm. Results: The mean CWT at the second intercostal space, the midclavicular line, was shorter than the CWT at the 5th intercostal space, the anterior axillary line. However, the percentage of patients whose CWT was greater than 45 mm was larger when measured anteriorly (8.2%) that when measure laterally (5.7%). Female patients and those older than 60 were more likely to have an anterior CWT greater than 45 mm (28.2% for females and 15.5% for those older than 60). Conclusion: The percentage of trauma victims in Korea whose CWT is greater than 45 mm is lower than the values previously reported by other countries. However, females and older patients tend to have thicker chest walls, so the lateral approach would be suggested when performing needle decompression for such patients with suspected tension pneumothoraces.

Background : As each human has a look in the face of oneself, he or she has a look of him or herself in the shape of the body also. And for the shape of the body which gives a big clue in diagnosis in musculoskeletal disorders. Therefor many means are used and developed for diagnosis through body shape or posture analysis for musculoskeletal disorders. X-ray, CT, MRI has been used for diagnosis through image in this way to tell about the inside of the human body. On the other side, moire topography was used for information about the exterior of the human body, but yet only minimal information such as the number of contour lines in each side was available. Therefor there were a few studies to use moire topography or other methods to get information about the surface of the human body in numeric values. The instrument used in this study which is a laser projection moire, is another trial to get numeric data about the surface of the human body. The instrument is composed of laser projector and a computer software to recompose and analyse the image data into depth, height, angle and length. Objectives : The study was focused on whether the instrument is reliable for clinic use, and to seek the proper environment and posture for the examination, and among the data the software provides, which items are more reliable and useful. Methods : For reproductivity and repeatability, 4 testers tested 2 persons. And to how if the body shape changes according to the posture and which posture gives the most reliable data, the test was performed in 6 different positions. Results : Result, the instrument showed sufficient repeatability and reproductivity for clinical use. And among the items the software provides, the length of the back, the angle of the back in the sagittal and coronal plane showed reliable results. And there was difference in the results according to the posture, and Therefor, in following studies using this instrument or similar type of posture analysing instruments, the length of the back, the angle of the back in the sagittal and coronal plane could be reliable item to use.
