Tissue engineering (TE) has the potential to improve the outcome for patients with osteoarthritis (OA). The successful clinical translation of this technique as part of a therapy requires the ability to measure extracellular matrix (ECM) production of engineered tissues in vitro, in order to ensure quality control and improve the likelihood of tissue survival upon implantation. Conventional techniques for assessing the ECM content of engineered cartilage, such as biochemical assays and histological staining are inherently destructive...

Previous studies have shown the contamination of rivers and streams caused by tannery effluents (TE). However, the effects of TE on amphibians are still unknown. Thus, we evaluated whether the TE, even at low concentrations (0.2%), could cause asymmetric development (inferred through the fluctuating asymmetry indices (FA)) and changes in morphological characteristics of Physalaemus cuvieri larvae. Accordingly, the tadpoles were distributed in groups non-exposed (n=160) and exposed (n=160) to this TE, for 15days...

This study first investigated the importance of ball control and (self-reported) self-regulatory skills in achieving the elite level in basketball. The second aim was to gain insight into the development of, and association between ball control and (self-reported) self-regulatory skills that contribute to achieving the elite level, with taking into account positional differences. Talented male players (N = 73; age 16.56 ± 1.96) completed the STARtest to measure ball control and a questionnaire to measure (self-reported) self-regulation from 2008-2012...

Brittany Dowling, April L McPherson, James M Paci
BACKGROUND: Passive ankle dorsiflexion range of motion (DROM) measures have been identified as a risk factor for injury during landings. However, passive measurements might not be indicative of dynamic ankle movement, whereas a weightbearing ROM might be a better tool when evaluating movement. The purpose of this study was to investigate the relationship between weightbearing DROM and sagittal plane landing mechanics in a single leg drop jump task. METHODS: 73 male athletes (22...

PURPOSE: The correlation between tibial tuberosity-trochlear groove distance (TT-TG) and joint size, taking into account several different parameters of knee joint size as well as lower limb dimensions, is evaluated in order to assess whether TT-TG indices should be used in instead of absolute TT-TG values. METHODS: This study comprised a retrospective analysis of knee CT scans, including 36 cases with patellofemoral instability (PFI) and 30 controls. Besides TT-TG, five measures of knee joint size were evaluated in axial CT slices: medio-lateral femur width, antero-posterior lateral condylar height, medio-lateral width of the tibia, width of the patella and the proximal-distal joint size (TT-TE)...

Trace element (TE) requirements of Methanothermobacter okinawensis and Methanothermobacter marburgensis were examined in silico, and using closed batch and fed-batch cultivation experiments. In silico analysis revealed genomic differences among the transport systems and enzymes related to the archaeal Wood-Ljungdahl pathway of these two methanogens. M. okinawensis responded to rising concentrations of TE by increasing specific growth rate (µ) and volumetric productivity (MER) during closed batch cultivation, and can grow and produce methane (CH4) during fed-batch cultivation...

BACKGROUND: Sexual assault is a global concern with post-traumatic stress disorder (PTSD), one of the common sequelae. Early intervention can help prevent PTSD, making identification of those at high risk for the disorder a priority. Lack of representative sampling of both sexual assault survivors and sexual assaults in prior studies might have reduced the ability to develop accurate prediction models for early identification of high-risk sexual assault survivors. METHODS: Data come from 12 face-to-face, cross-sectional surveys of community-dwelling adults conducted in 11 countries...

BACKGROUND AND OBJECTIVES: Olaratumab is a recombinant human monoclonal antibody that binds to platelet-derived growth factor receptor-α (PDGFRα). In a randomized phase II study, olaratumab plus doxorubicin met its predefined primary endpoint for progression-free survival and achieved a highly significant improvement in overall survival versus doxorubicin alone in patients with advanced or metastatic soft tissue sarcoma (STS). In this study, we characterize the pharmacokinetics (PKs) of olaratumab in a cancer patient population...

Brucellosis, a zoonotic disease particularly affecting goats, emerged in Thailand in 2003, resulting in both an occupational hazard for goat keepers and livestock officers, and production losses. Farm management practices have been identified as risk factors associated with Brucella sero-positivity in many studies. Our finding in this study should be considered in order to strengthen the system of biosecurity control in farm animals as one health approach. The objectives of the study were to describe the distribution of potential risk factors by types of goat farms and to document the prevalence of human Brucella sero-positivity among goat keepers and livestock officers in Nakhon Si Thammarat, Thailand...

High sulfation, low cost, and the status of heparin as an already FDA- and EMA- approved product, mean that its inclusion in tissue engineering (TE) strategies is becoming increasingly popular. However, the use of heparin may represent a naïve approach. This is because tissue formation is a highly orchestrated process, involving the temporal expression of numerous growth factors and complex signaling networks. While heparin may enhance the retention and activity of certain growth factors under particular conditions, its binding 'promiscuity' means that it may also inhibit other factors that, for example, play an important role in tissue maintenance and repair...

BACKGROUND: The safety of anticoagulation interruption in patients requiring surgical or invasive procedures remains unclear. We thus performed a systematic review and meta-analyses of randomized controlled trials (RCTs) and non-randomized studies (NRS). METHODS: MEDLINE, Embase and Central databases were searched to March 2017 without date or language restrictions. We considered RCTs and NRS comparing anticoagulation interruption with any anticoagulation (continuation or heparin bridging) in adult surgical patients taking oral anticoagulation...

Persistent insomnia is among the most frequent complaints in general practice. To identify genetic factors for insomnia complaints, we performed a genome-wide association study (GWAS) and a genome-wide gene-based association study (GWGAS) in 113,006 individuals. We identify three loci and seven genes associated with insomnia complaints, with the associations for one locus and five genes supported by joint analysis with an independent sample (n = 7,565). Our top association (MEIS1, P < 5 × 10(-8)) has previously been implicated in restless legs syndrome (RLS)...

Transposable elements (TEs) are DNA sequences that can move within the genome. TEs have greatly shaped the genomes, transcriptomes, and proteomes of the host organisms through a variety of mechanisms. However, TEs generally disrupt genes and destabilize the host genomes, which substantially reduce fitness of the host organisms. Understanding the genomic distribution and evolutionary dynamics of TEs will greatly deepen our understanding of the TE-mediated biological processes. Most TE insertions are highly polymorphic in Drosophila melanogaster, providing us a good system to investigate the evolution of TEs at the population level...

PURPOSE: Perioperative management of infants with esophageal atresia and tracheoesophageal fistula (EA/TEF) is frequently based on surgeon experience and dogma rather than evidence-based guidelines. This study examines whether commonly perceived important aspects of practice affect outcome in a contemporary multi-institutional cohort of patients undergoing primary repair for the most common type of esophageal atresia anomaly, proximal EA with distal TEF. METHODS: The Midwest Pediatric Surgery Consortium conducted a multicenter, retrospective study examining selected outcomes on infants diagnosed with proximal EA with distal TEF who underwent primary repair over a 5-year period (2009-2014), with a minimum 1-year follow up, across 11 centers...

Until now there are no completely effective parasite-specific pharmaceuticals or immunotherapies for treatment against the zoonotic cryptosporidiosis. Sushi domain (CpSushi) is an important functional domain in Cryptosporidium parvum putative rhoptry protein-1 (CpPRP1) which is the only reported C. parvum rhoptry protein and may play key role in the course of invasion. Here, a 708 bp fragment encoding the CpSushi domain was amplified and expressed in E. coli. Immunofluorescence detection showed that CpSushi was located on the surface of C...

It is estimated that 13.000 to 22.000 individuals suffer from inhalational burns each year in the United States alone. Despite these high numbers, inhalational burns remain a major challenge to otolaryngologists. In this paper, a review of literature is presented in order to provide otolaryngologists with a systematic approach to patients with inhalational burns to optimize treatment, cost, morbidity and, most importantly, mortality. For this purpose, a broad PubMed search was conducted. The available literature was found to highlight the importance of airway management in terms of the timing of intubation, method of intubation, trachea-esophageal (TE) fistula formation and TE rupture...
