Probiotics, enzymes, organic acids, oligosaccharides, antioxidants, and other functional materials are actively being explored as alternatives to antibiotics. Probiotics include live beneficial microorganisms that colonize the intestinal tract and competitively inhibit attachment and growth of harmful microbes. Probiotics also increase feed efficiency by assisting in nutrient absorption and digestion. The current study was conducted in order to evaluate the effect of a new probiotic, CS-A, as a dietary supplement of a fermented product on growth performance, feed intake, and feed conversion efficiency in broiler chickens, and to evaluate its value as an alternative for antibiotics used as a feed additive. Antibacterial and anti-inflammatory effects of CS-A were investigated in vitro and the in vivo effects of a constant concentration of supplemented CS-A on growth rate and feed efficiency were evaluated. In addition, the safety of CS-A was assessed by examination of common symptoms and mortality. Determination of minimal inhibitory concentration revealed an excellent antibacterial effect of CS-A. Cytotoxicity was low and anti-inflammatory effects were achieved at the effective concentration of CS-A. Supplementation with 0.1% CS-A resulted in a feed efficiency score of 1.84 in broilers, compared to 2.00 in the control group. There were no adverse clinical findings, necropsy findings, hematology, and altered serum biochemistry parameters, and no mortality. Thus, it is concluded that CS-A is safe and effective as a feed additive.

The development of in vitro assays has been recommended to screening and test-ing the potential endocrine disruptors (EDs). These assay systems focus only on identifying thethe thyroid hormone (TH) disruptors. The aim of this study was to evaluate a test system to detectTH disruptors using rat pituitary tumor GH3 cells. The test system is based on the TH-dependentincrease in growth rate. As expected, L-3,5,3-triiodothyronine (T3) markedly induced a morphologicalchange in GH 3 cells from flattened fibroblastic types to rounded or spindle-shaped types. T3 stimu-lated GH3 cell growth in a dose-dependent manner with the maximum growth-stimulating effect9 M. In addition, T3 increased the release of growth hor-mone and prolactin into the medium of the GH3 cells culture. Using this assay system, the TH-dis-rupting activities of bisphenol A (BPA) and its related compounds were examined. BPA,dimethylbisphenol A (DMBPA), and TCI-EP significantly enhanced the growth of GH3 cells in therange of 1 × 10-5M to 1 × 10-6M concentrations. In conclusion, this in vitro assay system might bestandardization before it can be used as a broad-based screening tool.

Purpose : This study evaluated the impact of the presence and aspect of mandibular third molars to the mandible angle fracture or condyle fractures in Korean. Materials and Methods : A retrospective study was designed for patients attending the division of Oral and Maxillofacial Surgery, Kang-dong sacred heart hospital for treatment of mandibular fracture from January 2006 to September 2010. The primary variable was the presence of mandibular third molar and the secondary variable was the aspects of third molar impaction. Mandibular third molars were classified by the impaction depth and the available space as Pell & Gregory system. Outcome variables were the presence of mandibular angle fracture or condyle fracture. Also the source of trauma, age, sex were studied. Hospital charts, radiographs were used for study. Statistic analysis was done with descriptive statistics, the X2-test, linear-bylinear association. P value under 0.05 was considered significant statistically. Results : The number of involved patients was 86. The ratio of male to female patients was about 9:1 for angle fracture and 7:3 for condyle fracture. The most common source of trauma was assault for angle fracture and fall down for condyle fracture. The presence of mandibular third molar increased frequency of angle fracture and decreased condyle fracture with larger impaction depth. But available space of mandibular third molar did not show high association with angle or condyle fractures. Conclusion : Preventive extraction of mandibular third molar is recommended for patients with high risk of angle fracture. Male patients at their third decade or martial artists, police officer could be the case. But it is not recommended for patients with low risk of angle fracture and high risk of condyle fracture relatively. Elder female patients without any symptom on their third molar could be the case.

Kang, Taegyu,Jeong, Sinyoung,Kang, Homan,Kim, Jaehi,Kim, Hyung-Mo,Kyeong, San,Lee, Sang Hun,Jeong, Dae Hong,Jun, Bong-Hyun,Lee, Yoon-Sik Elsevier 2015 Journal of industrial and engineering chemistry Vol.32 No.-

<P><B>Abstract</B></P> <P>Surface-enhanced Raman scattering (SERS) has received much attention due to ultra-high sensitivity in detection of biological and chemical analytes. When SERS is used as tagging probe, several strong points such as high sensitivity and multiplexing capability can resolved several key issues with current optical tagging materials. Our group has reported synthesis of silica-coated silver nanoparticles (NPs) embedded silica NPs (SERS Dots) for bio-applications. Here, we designed and synthesized a new type of hollow-shell type SERS active NP (yolk–shell SERS Dots), which are aggregated silver NPs with a hollow silica nanostructure. The yolk–shell SERS Dots were prepared by adding NaBH<SUB>4</SUB> to SERS Dots, resulting in the prepared NPs exhibiting 2.3 times stronger SERS signals due to aggregation of silver NPs inside the silica shells and generating several hot spots among those silver NPs. Moreover, biotin-conjugated yolk–shell type SERS dots successfully bound streptavidin-Cy5 to demonstrate the potential of yolk–shell SERS dots for bio-detection. These yolk–shell SERS Dots have great potential for bio-imaging and drug delivery applications.</P>

( Kang Won Lee ),( Bo Ra Keum ),( Seung Han Kim ),( Jae Min Lee ),( In Kyung Yoo ),( Hyuk Soon Choi ),( Eun Sun Kim ),( Yoon Tae Jeen ),( Hoon Jai Chun ),( Hong Sik Lee ),( Chang Duck Kim ),( Ho Sang 대한내과학회 2015 대한내과학회 추계학술대회 Vol.2015 No.1

Background: About 40,000 to 60,000 images are analyzed for a complete interpretation of a single capsule endoscopy case. Diagnostic yield of capsule endoscopy for occult gastro-intestinal bleeding is between 60 and 70 percents. However overall abnormality detection rate is roughly 30 to 50 percents due to excessive workload which can result in examiners missing significant lesions during the review of capsule endoscopy images. Because of the poor detection rate, meticulous analysis ofimages has become critical for safe patient-care. Impact of re-review on the detection rate of abnormal lesions is not known. In this study, we compare the detection rates of abnormal findings in different re-review methods for capsule endoscopy. Methods: Capsule endoscopy for 20 patients were conducted. Indications include obscure gastro-intestinal bleeding, small bowel tumor and chronic abdominal pain. Four endoscopists interpreted capsule endoscopy images. Second reviews were performed by the same clinician (A-A) and other clinician (A-B). Three modes of interpretation of capsule endoscopy were compared; A vs. A-A vs. A-B. PillCami SB, GiveniImaging Ltd. was used for the evaluation. Collected images were reviewed with RAPID Readeri 5. Consensus standard of small bowel diagnosis had been established by joint review sessions with highly experienced endoscopists. Results: The mean age of subjects was 52.4±20.03 (12 Male, 8 Female). The detection rate of the re-reviewed group done by a single clinician (A-A) was higher than the single review group (A) (82.7% vs. 55.5%, p<0.05). The detection rate of re-analysis by different clinicians (A-B) was also higher than the single review group (A) (85.5% vs. 55.5%, p<0.05). Conclusions: Because re-reviewing capsule endoscopy added more information for patients, re-review may be effective enough to be considered as a routine interpretation protocol.
