Peste des petits ruminants virus (PPRV) causes the acute, highly contagious disease peste des petits ruminants (PPR) that affects small domestic and wild ruminants. PPR is of importance in the small livestock-keeping industry in Tanzania, especially in rural areas as it is an important source of livelihood. Morbidity and case fatality rate can be as high as 80-100% in naïve herds; however, in endemic areas, morbidity and case fatality range between 10 and 100% where previous immunity, age, and species of infected animal determine severity of outcome...

Increasing evidence supports the idea that bone morphogenetic proteins (BMPs) regulate cartilage maintenance in the adult skeleton. The aim of this study is to obtain insight into the regulation of BMP activities in the adult skeletal system. We analyzed expression of Noggin and Gremlin1, BMP antagonists that are known to regulate embryonic skeletal development, in the adult skeletal system by Noggin-LacZ and Gremlin1-LacZ knockin reporter mouse lines. Both reporters are expressed in the adult skeleton in a largely overlapping manner with some distinct patterns...

A multi-institutional study was undertaken to determine whether mandibular canal (MC) invasion and mandibular medullary bone invasion are independent factors in lower gingival squamous cell carcinoma (SCC). A total of 345 patients with lower gingival SCC were retrospectively reviewed. Mandibular bone invasion was categorized into three types; no bone invasion; invasion through cortical bone (medullary); and MC invasion. The overall survival rate and factors affecting local, regional, and distant failures were assessed by Cox proportional hazards regression analysis and Kaplan-Meier estimates...

We consider recurrent events of the same type that occur during alternating restraint and non-restraint time periods. This research is motivated by a study on juvenile recidivism, where the probationers were followed for re-offenses during alternating placement periods and free-time periods. During the placement periods, the probationers were under a restricted environment with direct supervision of the probation officers. During the free-time periods, the probationers were released to home and not under direct supervision...

Single, double, and triple hindfoot arthrodeses are used to correct hindfoot deformities and relieve chronic pain. However, joint fusion may lead to dysfunction in adjacent articular surfaces. We compared range of motion in adjacent joints before and after arthrodesis to determine the effects of each procedure on joint motion. The theory of moment of couple, bending moment and balanced loading was applied to each of 16 fresh cadaver feet to induce dorsiflexion, plantarflexion, internal rotation, external rotation, inversion, and eversion...

Neutrophil to lymphocyte ratio (NLR) has been found to be significantly associated with pancreatic cancer (PC) survival. However, no existing studies discussed the association between neutrophil count, lymphocyte count, and PC survival jointly. In this study, we aimed to analyze the influence of neutrophil and lymphocyte counts measured at disease diagnosis on the overall survival (OS) of PC. A total of 288 PC patients diagnosed between January 1, 2012, and December 31, 2013, were retrospectively selected from a population-based electronic inpatients database...

Linear mixed effects models are widely used to analyze a clustered response variable. Motivated by a recent study to examine and compare the hospital length of stay (LOS) between patients undertaking percutaneous coronary intervention (PCI) and coronary artery bypass graft (CABG) from several international clinical trials, we proposed a bivariate linear mixed effects model for the joint modeling of clustered PCI and CABG LOS's where each clinical trial is considered a cluster. Due to the large number of patients in some trials, commonly used commercial statistical software for fitting (bivariate) linear mixed models failed to run since it could not allocate enough memory to invert large dimensional matrices during the optimization process...

Dysplasia epiphysealis hemimelica (DEH) is a rare developmental disorder characterized by osteocartilaginous overgrowth in one or more epiphyses. The disease usually involves a single limb or is hemimelic (lateral or medial compartment), and lower extremities are more frequently affected than upper extremities. Here we present clinical and radiological findings for a male DEH patient at 1.5 and 3.5 years of age. The radiographs obtained at first presentation showed minimal osseous overgrowth and irregularity at the epiphyses around the left knee and ankle joints, respectively...

OBJECTIVES: We aimed to test for differences in hip joint range of motion (ROM) between captive and free-ranging rhesus macaques (Macaca mulatta), particularly for hip joint abduction, which previous studies of captive macaques have found to be lower than predicted. MATERIALS AND METHODS: Hip ROM was assessed following standard joint measurement methodology in anesthetized adult free-ranging rhesus macaques (n = 39) from Cayo Santiago, and compared with published ROM data from captive rhesus macaques (n = 16) (Hammond, , American Journal of Physical Anthropology)...

INTRODUCTION: There have been various studies from India describing the acute presentation and the long-term sequalae of Chikungunya (CHIKV) infection. However, there are very few studies discussing the Chikungunya-Dengue (DENV) co-infection from Western India. The present project was undertaken to study the clinical features of Dengue and Chikungunya co-infection and compare with Chikungunya mono-infection; correlate the clinical findings with seroprevalence and molecular identification of Dengue and Chikungunya using IgM ELISA and RTPCR...

Understanding protein-protein interactions is central to our understanding of almost all complex biological processes. Computational tools exploiting rapidly growing genomic databases to characterize protein-protein interactions are urgently needed. Such methods should connect multiple scales from evolutionary conserved interactions between families of homologous proteins, over the identification of specifically interacting proteins in the case of multiple paralogs inside a species, down to the prediction of residues being in physical contact across interaction interfaces...

Structured sparsity, as an extension of standard sparsity, has shown the outstanding performance when dealing with some highly correlated variables in computer vision and pattern recognition. However, the traditional mixed (L1, L2) or (L1, L∞) group norm becomes weak in characterizing the internal structure of each group since they cannot alleviate the correla-tions between variables. Recently, nuclear norm has been vali-dated to be useful for depicting a spatially structured matrix variable. It considers the global structure of the matrix variable but overlooks the local structure...

Hitherto, most quantitative trait loci (QTL) of maize growth and biomass yield have been identified for a single time point, usually the final harvest stage. Through this approach cumulative effects are detected, without considering genetic factors causing phase-specific differences in growth rates. To assess the genetics of growth dynamics, we employed automated non-invasive phenotyping to monitor the plant sizes of 252 diverse maize inbred lines at eleven different developmental time points. 50 k SNP array genotype data were used for genome wide association mapping and genomic selection...

BACKGROUND: Instrument assisted soft tissue mobilization (IASTM) is a popular treatment for myofascial restriction. IASTM uses specially designed instruments to provide a mobilizing effect to scar tissue and myofascial adhesions. Several IASTM tools and techniques are available such as the Graston® technique. Currently, there are no systematic reviews that have specifically appraised the effects of IASTM as a treatment or to enhance joint range of motion (ROM). PURPOSE: The purpose of this study was to systematically appraise the current evidence assessing the effects of IASTM as an intervention to treat a musculoskeletal pathology or to enhance joint ROM...

: : Trauma-induced heterotopic ossification (HO) occurs after severe musculoskeletal injuries and burns, and presents a significant barrier to patient rehabilitation. Interestingly, the incidence of HO significantly increases with repeated operations and after resection of previous HO. Treatment of established heterotopic ossification is challenging because surgical excision is often incomplete, with evidence of persistent heterotopic bone. As a result, patients may continue to report the signs or symptoms of HO, including chronic pain, nonhealing wounds, and joint restriction...

The harmonic mean of the relative performance of genotypic predicted value (HMRPGV) method has been used to measure the genotypic stability and adaptability of various crops. However, its use in cotton is still restricted. This study aimed to use mixed models to select cotton genotypes that simultaneously result in longer fiber length, higher fiber yield, and phenotypic stability in both of these traits. Eight trials with 16 cotton genotypes were conducted in the 2008/2009 harvest in Mato Grosso State. The experimental design was randomized complete blocks with four replicates of each of the 16 genotypes...

INTRODUCTION: The glenoid labrum is frequently torn in traumatic glenohumeral dislocation; arthroscopic repair is the standard method of treatment. The complications associated with this repair are pulling out of metal suture anchors, chondrolysis and joint infection. The infection of joint after arthroscopy is less than 1%. Staphylococcus is most common organism and rarely followed by Pseudomonas aeruginosa. We report a case of infected shoulder with chondrolysis of the joint and pulled out metal suture anchor lying inside the joint after Bankart's repair...
