Sectioning of the Anterolateral Ligaments in Anterior Cruciate Ligament Sectioned Knees Increases Internal Rotation of the Knee Joint: A Systematic Review and Meta-analysis of Cadaveric Studies.

Purpose: To investigate whether anterolateral ligament (ALL) sectioning (sALL) in the anterior cruciate ligament (ACL)-sectioned (sACL) knee increases the anterior tibial translation (ATT) or internal rotation (IR) of the knee from previous cadaveric biomechanical studies.

Methods: Multiple comprehensive literature databases, including PubMed (MEDLINE), EMBASE, and Cochrane Library, were searched for studies evaluating the in vitro biomechanical function of ALL. This meta-analysis compared the increased ATT and IR between the sACL and sACL + sALL knees at 30°, 60°, and 90° of knee flexion.

Histopathological Findings and Metagenomic Analysis of Esophageal Papillary Proliferation Identified in Laying Broiler Breeders.

White or pale-yellow nodules 2-7 mm in length were observed in the esophageal lumen in a number of laying broiler breeders with reduced laying rates. Metaplasia of the mucosal epithelial layer and mucous gland, as well as lymphocyte infiltration under the esophageal mucous gland and epithelial cell layer, were observed, which we found were caused by vitamin A deficiency. In one chicken, however, the stratified squamous epithelial cells of the esophagus were completely replaced by increased numbers of ducts/ductules, lymphocytes, and connective tissue, resulting in a papillary morphology.

Revision Arthroplasty Using a MUTARS® Prosthesis in Comminuted Periprosthetic Fracture of the Distal Femur.

Periprosthetic fractures after total knee arthroplasty (TKA) are gradually increasing, reflecting extended lifespan, osteoporosis, and the increasing proportion of the elderly during the past decade. Supracondylar periprosthetic femoral fracture is a potential complication after TKA. Generally, open reduction and internal fixation are the conventional option for periprosthetic fracture after TKA.

Can Alarming Improve Compliance with Weekly Bisphosphonate in Patients with Osteoporosis?

Background: Although bisphosphonate is effective for the prevention and treatment of osteoporosis, poor medication compliance is a key-limiting factor. We determined whether alarm clock could improve compliance with weekly bisphosphonate in patients with osteoporosis, by comparing with age- and gender-matched control group.

Methods: Fifty patients with osteoporosis were recruited and participated in alarm clock group.

Plasma homocysteine level and hepatic sulfur amino acid metabolism in mice fed a high-fat diet.

Purpose: Obesity, a feature of metabolic syndrome, is a risk factor for cardiovascular disease, and elevated plasma homocysteine is associated with increased cardiovascular risk. However, little published information is available concerning the effect of obesity on homocysteine metabolism.

Methods: Hepatic homocysteine metabolism was determined in male C57BL/6 mice fed a high-fat diet for 12 weeks.

Expression of secreted mucins (MUC2, MUC5AC, MUC5B, and MUC6) and membrane-bound mucin (MUC4) in the lungs of pigs experimentally infected with Actinobacillus pleuropneumoniae.

The expression patterns of different secreted (MUC2, MUC5AC, MUC5B, and MUC6) and membrane-bound (MUC4) mucins were determined immunohistochemically in the lungs of pigs experimentally infected with Actinobacillus pleuropneumoniae. Forty-seven-week-old colostrum-deprived pigs were randomly allocated to infected (n=20) or control groups (n=20). Five infected and uninfected pigs were euthanized at 0, 6, 12, and 48 h post-inoculation (hpi).

Expression of mucins on the mucosal surface of lungs of 4-week-old pigs.

The aim of this study was to determine the immunoreactivity of normal small bronchial, bronchiolar, respiratory bronchiolar, and interalveolar epithelium using antibodies to six mucins: MUC1, MUC2, MUC4, MUC5AC, MUC5B, and MUC6. The large, gel-forming secreted mucins MUC2, MUC5AC, and MUC5B were widely expressed in the lower respiratory tract. The results of this study demonstrate that these secreted mucins form a gel to cover and protect the mucosal surface in the lower respiratory tract of pigs.

Distribution of capsular serotypes and virulence markers of Streptococcus suis isolated from pigs with polyserositis in Korea.

The objective of this study was to determine the capsular serotypes and potential virulence factors of Streptococcus suis isolated from pigs with polyserositis. Among the 24 isolates evaluated, serotype 3 [7 (29%) of the isolates] and serotype 4 [5 (21%)] were the most common. The isolates were also studied for the presence of the genes mrp, epf, and sly, which encode muramidase-released protein (MRP), extracellular factor (EF), and suilysin (SLY), respectively.

Association between colorectal adenoma and coronary atherosclerosis detected by CT coronary angiography in Korean men; a cross-sectional study.

Background: Colorectal adenoma and coronary artery disease (CAD) appear to share common risk factors, such as male gender, diabetes mellitus, smoking, and obesity. We investigated the relationship between colorectal adenoma and coronary atherosclerosis, as a risk factor for colorectal adenoma.

Methods: A cross-sectional study was conducted on Korean men who presented for a health check-up.

Development of in situ hybridization for the detection of Mycoplasma hyorhinis in formalin-fixed paraffin-embedded tissues from naturally infected pigs with polyserositis.

The aim of this study was to develop in situ hybridization for detection of Mycoplasma hyorhinis in formalin-fixed, paraffin-wax-embedded tissues from pigs with polyserositis. M. hyorhinis was isolated from the spleen (2 pigs) and pericardium (1 pig).

Expression of mucins in the mucosal surface of small intestines in 1 week-old pigs.

The aim of this study was to determine the immunoexpression of mucins in jejunal and ileal villous epithelium using six antibodies against MUC1, MUC2, MUC4 MUC5AC, MUC5B and MUC6. The immunohistochemical score for MUC1 has significantly intense staining compared with MUC2 (P=0.008) and the immunohistochemical socre for MUC4 and MUC 6 has significantly intense staining compared with MUC2 (P=0.

The relation between non-alcoholic fatty liver disease and the risk of coronary heart disease in Koreans.

Objectives: Non-alcoholic fatty liver disease (NAFLD) is known to be related to factors that predict the development of coronary heart disease (CHD), such as dyslipidemia, central obesity, and metabolic syndrome (MS). The aim of this study was to determine whether individuals with NAFLD have an elevated risk of CHD, as estimated using the Framingham risk score (FRS).

Methods: A total of 21,130 individuals who underwent a voluntary general health examination were recruited.

Anti-gastric cancer effects of celecoxib, a selective COX-2 inhibitor, through inhibition of Akt signaling.

Background And Aim: Previously, we showed that treatment with celecoxib significantly reduced the number of viable gastric cancer cells, in a dose- and time-dependent manner. However, the specific anti-cancer effects of celecoxib on gastric cancer cells have not been clarified. The present in vitro study was carried out to investigate the mechanism involved in the anti-gastric cancer effects of celecoxib.

Is Metabolic Syndrome One of the Risk Factors for Gallbladder Polyps Found by Ultrasonography during Health Screening?

Background/aims: We conducted this study to identify the risk factors for finding gallbladder polyps (GBP) in Korean subjects during health screening, and to determine the nature of the association between the presence of metabolic syndrome (MS) and the development of GBP METHODS: A total of 1,523 subjects were enrolled, comprising 264 with GBP (81 women and 183 men) and 1,259 controls (696 women and 563 men with normal GB). Body mass index (BMI), waist circumference (WC), blood pressure (BP), insulin, fasting blood sugar (FBS), lipids, liver enzymes, hepatitis B antigens (HBs Ag), and hepatitis C antibodies (HCV Ab) were measured. MS was considered to be present when three or more of the NCEP-ATPIII (National Cholesterol Education Program-Adult Treatment Panel III) criteria were satisfied.
