Architectural specialization of the intrinsic thoracic limb musculature of the American badger (Taxidea taxus)

Evaluation of the relationships between muscle structure and digging function in fossorial species is limited. Badgers and other fossorial specialists are expected to have massive forelimb muscles with long fascicles capable of substantial shortening for high power and applying high out‐force to the substrate. To explore this hypothesis, we quantified muscle architecture in the thoracic limb of the American badger (Taxidea taxus) and estimated the force, power, and joint torque of its intrinsic musculature in relation to the use of scratch‐digging behavior. Architectural properties measured were muscle mass, belly length, fascicle length, pennation angle, and physiological cross‐sectional area. Badgers possess hypertrophied shoulder flexors/humeral retractors, elbow extensors, and digital flexors. The triceps brachii is particularly massive and has long fascicles with little pennation, muscle architecture consistent with substantial shortening capability, and high power. A unique feature of badgers is that, in addition to elbow joint extension, two biarticular heads (long and medial) of the triceps are capable of applying high torques to the shoulder joint to facilitate retraction of the forelimb throughout the power stroke. The massive and complex digital flexors show relatively greater pennation and shorter fascicle lengths than the triceps brachii, as well as compartmentalization of muscle heads to accentuate both force production and range of shortening during flexion of the carpus and digits. Muscles of most functional groups exhibit some degree of specialization for high force production and are important for stabilizing the shoulder, elbow, and carpal joints against high limb forces generated during powerful digging motions. Overall, our findings support the hypothesis and indicate that forelimb muscle architecture is consistent with specializations for scratch‐digging. Quantified muscle properties in the American badger serve as a comparator to evaluate the range of diversity in muscle structure and contractile function that exists in mammals specialized for fossorial habits.

Circulating MiR-19b-3p, MiR-134-5p and MiR-186-5p are Promising Novel Biomarkers for Early Diagnosis of Acute Myocardial Infarction

Background/Aims: Recent studies have shown that circulating microRNAs (miRNAs) are emerging as promising biomarkers for cardiovascular diseases. This study aimed to determine whether miR-19b-3p, miR-134-5p and miR-186-5p can be used as novel indicators for acute myocardial infarction (AMI). Methods: To investigate the kinetic expression of the three selected miRNAs, we enrolled 18 patients with AMI and 20 matched controls. Plasma samples were collected from each participant, and total RNA was extracted. Quantitative real-time PCR and ELISA assays were used to investigate the expression of circulating miRNAs and cardiac troponin I (cTnI), respectively. Plasma samples from another age- and gender-matched cohort were collected to investigate the impact of medications for AMI on the expression of the selected miRNAs. Results: Levels of plasma miR-19b-3p, miR-134-5p and miR-186-5p were significantly increased in early stage of AMI. Plasma miR-19b-3p and miR-134-5p levels reached peak expression immediately after admission (T0), whereas miR-186-5p achieved peak expression at 4 h after T0. All of these times were earlier than the peak for cTnI (8 h after T0). In addition, all three miRNAs were positively correlated with cTnI. Receiver Operating Characteristic (ROC) analysis indicated that each single miRNA showed considerable diagnostic efficiency for predicting AMI. Furthermore, combining all three miRNAs in a panel increased the efficiency of distinguishing between patients with AMI and controls. Moreover, we found that heparin and medications for AMI did not impact the expression of these circulating miRNAs. Conclusion: Circulating miR-19b-3p, miR-134-5p and miR-186-5p could be considered promising novel diagnostic biomarkers for the early phase of AMI.
Therapeutic interference with leukocyte recirculation in multiple sclerosis

Multiple sclerosis (MS) is an immune‐mediated disease where T cells are thought to initiate an inflammatory reaction in the brain and spinal cord, resulting in demyelination and axonal pathology. Interfering with the activation and recruitment of immune cells reduces disease activity in MS. We review the mechanism of action and treatment effects of natalizumab and fingolimod, which interfere with the recruitment of pathogenic immune cells in MS. Fingolimod blocks the egress of activated lymphocytes from lymph nodes by binding to the sphingosine‐1‐phosphate (S1P) receptor 1, but may also have effects on S1P receptor‐expressing cells within the central nervous system (CNS). Natalizumab reduces the migration of lymphocytes to the CNS by binding to the α4 integrin very late antigen 4. Fingolimod and natalizumab also have other effects, but these are less well understood. Both treatments are efficacious in reducing relapses, accumulation of persisting disability and magnetic resonance imaging disease activity. Both treatments are safe and well tolerated in the majority of patients, but due to a potential for serious side effects they are licensed as second line therapies or for treatment of highly active MS in most European countries. We conclude that fingolimod and natalizumab have well known effects on the migration of immune cells in MS and have substantial effects on disease activity in relapsing−remitting MS. Additional effects on disease progression, potential effects within the CNS and other effects on immune cells are still being clarified.
Individual ball possession in soccer

This paper describes models for detecting individual and team ball possession in soccer based on position data. The types of ball possession are classified as Individual Ball Possession (IBC), Individual Ball Action (IBA), Individual Ball Control (IBC), Team Ball Possession (TBP), Team Ball Control (TBC) und Team Playmaking (TPM) according to different starting points and endpoints and the type of ball control involved. The machine learning approach used is able to determine how long the ball spends in the sphere of influence of a player based on the distance between the players and the ball together with their direction of motion, speed and the acceleration of the ball. The degree of ball control exhibited during this phase is classified based on the spatio-temporal configuration of the player controlling the ball, the ball itself and opposing players using a Bayesian network. The evaluation and application of this approach uses data from 60 matches in the German Bundesliga season of 2013/14, including 69,667 IBA intervals. The identification rate was F = . 88 for IBA and F = . 83 for IBP, and the classification rate for IBC was κ = . 67. Match analysis showed the following mean values per match: TBP 56:04 ± 5:12 min, TPM 50:01 ± 7:05 min and TBC 17:49 ± 8:13 min. There were 836 ± 424 IBC intervals per match and their number was significantly reduced by -5.1% from the 1st to 2nd half. The analysis of ball possession at the player level indicates shortest accumulated IBC times for the central forwards (0:49 ± 0:43 min) and the longest for goalkeepers (1:38 ± 0:58 min), central defenders (1:38 ± 1:09 min) and central midfielders (1:27 ± 1:08 min). The results could improve performance analysis in soccer, help to detect match events automatically, and allow discernment of higher value tactical structures, which is based on individual ball possession.
Saxagliptin and cardiovascular outcomes in patients with type 2 diabetes mellitus.

BACKGROUND The cardiovascular safety and efficacy of many current antihyperglycemic agents, including saxagliptin, a dipeptidyl peptidase 4 (DPP-4) inhibitor, are unclear. METHODS We randomly assigned 16,492 patients with type 2 diabetes who had a history of, or were at risk for, cardiovascular events to receive saxagliptin or placebo and followed them for a median of 2.1 years. Physicians were permitted to adjust other medications, including antihyperglycemic agents. The primary end point was a composite of cardiovascular death, myocardial infarction, or ischemic stroke. RESULTS A primary end-point event occurred in 613 patients in the saxagliptin group and in 609 patients in the placebo group (7.3% and 7.2%, respectively, according to 2-year Kaplan-Meier estimates; hazard ratio with saxagliptin, 1.00; 95% confidence interval [CI], 0.89 to 1.12; P=0.99 for superiority; P<0.001 for noninferiority); the results were similar in the "on-treatment" analysis (hazard ratio, 1.03; 95% CI, 0.91 to 1.17). The major secondary end point of a composite of cardiovascular death, myocardial infarction, stroke, hospitalization for unstable angina, coronary revascularization, or heart failure occurred in 1059 patients in the saxagliptin group and in 1034 patients in the placebo group (12.8% and 12.4%, respectively, according to 2-year Kaplan-Meier estimates; hazard ratio, 1.02; 95% CI, 0.94 to 1.11; P=0.66). More patients in the saxagliptin group than in the placebo group were hospitalized for heart failure (3.5% vs. 2.8%; hazard ratio, 1.27; 95% CI, 1.07 to 1.51; P=0.007). Rates of adjudicated cases of acute and chronic pancreatitis were similar in the two groups (acute pancreatitis, 0.3% in the saxagliptin group and 0.2% in the placebo group; chronic pancreatitis, <0.1% and 0.1% in the two groups, respectively). CONCLUSIONS DPP-4 inhibition with saxagliptin did not increase or decrease the rate of ischemic events, though the rate of hospitalization for heart failure was increased. Although saxagliptin improves glycemic control, other approaches are necessary to reduce cardiovascular risk in patients with diabetes.

Why and how? Addressing to the two most pertinent questions about pharmacovigilance in Ayurveda

Pharmacovigilance is the outcome of a natural and implied willingness of a physician to ensure safety to his patient. This is a discipline in medicine which pragmatises the principle of first do no harm towards a wider and systematic application in clinical practice. It is however important to understand that despite of its huge potential in ensuring a safe practice of medicine through knowledge of avoidable causes of adversities, its path has never been easy. Applying principles of pharmacovigilance into the realm of traditional medicine particularly to Ayurveda is even more difficult for the issues of why and how of pharmacovigilance in light of historical practice and anecdotal evidences of safety in Ayurveda. Application of pharmacovigilance in Ayurveda thereby demands a careful and thoughtful observation of its needs and its methods of application in order to to maximize its impacts to ensure the patient safety to every extent possible.
Disparities in the Estimation of Glomerular Filtration Rate According to Cockcroft‐Gault, Modification of Diet in Renal Disease‐4, and Chronic Kidney Disease Epidemiology Collaboration Equations and Relation With Outcomes in Patients With Acute Coronary Syndrome

Background A simple method to assess renal function is the estimated glomerular filtration rate, and it shows prognostic implications. However, it remains unknown which equation should be used in patients with acute coronary syndrome. We compared the ability and correlation of the Cockcroft‐Gault, Modification of Diet in Renal Disease‐4 (MDRD‐4), and Chronic Kidney Disease Epidemiology Collaboration (CKD‐EPI) equations and their predictive performance for major adverse cardiovascular events, all‐cause mortality, and major bleeding in a cohort of patients with acute coronary syndrome. Methods and Results Multicenter prospective registry involving 1699 consecutive patients with acute coronary syndrome from 3 tertiary institutions. At entry, renal function was assessed using the Cockcroft‐Gault, MDRD‐4, and CKD‐EPI‐creatinine equations. During 12 months of follow‐up, we recorded all major adverse cardiovascular events (composite of cardiovascular death, nonfatal myocardial infarction, and nonfatal ischemic stroke), bleeding events (Bleeding Academic Research Consortium classification), and all‐cause mortality. Receiver operating characteristic curve comparisons demonstrated that Cockcroft‐Gault equation had higher predictive ability compared with MDRD‐4 equation for major adverse cardiovascular events (0.651 versus 0.616; P=0.023), major bleeding (0.600 versus 0.551; P=0.005), and all‐cause mortality (0.754 versus 0.717; P=0.033), as well as higher predictive ability compared with CKD‐EPI equation for major bleeding (0.600 versus 0.564; P=0.018). Integrated discrimination improvement and net reclassification improvement analyses showed superior discrimination and reclassification of Cockcroft‐Gault equation. Decision curve analyses graphically demonstrated higher net benefit and clinical usefulness of the Cockcroft‐Gault equation in comparison with MDRD‐4 and CKD‐EPI equations. Conclusions In patients with acute coronary syndrome, the Cockcroft‐Gault equation presented superior predictive ability for major adverse cardiovascular events, major bleeding, and all‐cause mortality compared with MDRD‐4 equation, and superior predictive ability for major bleeding compared with CKD‐EPI equation. The Cockcroft‐Gault equation also showed higher net benefit and clinical usefulness.
Biophysical characterisation of biopharmaceuticals under defined flow fields

Flow induced aggregation occurs during the manufacturing process of biopharmaceuticals. An understanding of the effects of extensional flow is required as a means of predicting the response of experimental protein molecules to flow conditions during the down-stream manufacturing operations. Adequate prediction methods allow for elimination of proteins susceptible to flow induced aggregation, reducing development costs. An experimental device is designed and implemented to subject the proteins BSA, β2-microglobulin (β2m), granulocyte colony stimulating factor (G-CSF), and three monoclonal antibodies (mAbs) to a defined and quantified flow field dominated by extensional flow. CFD analysis is used to accurately characterise the flow field throughout the geometry. Through simulation and bespoke post-processing it is possible to determine the magnitude of extensional strain which the fluid is subjected to. The device is then modified to allow for a comparison to be made between the strain and shear which is inherent in any flow device. The work shows that the device induces protein aggregation after exposure to an extensional flow field for 0.36 – 1.8 ms, at concentrations as low as 0.5 mg ml−1. Correlation is drawn between the extent of aggregation and the applied strain rate, as well as protein concentration, structural properties, and sequence of the protein. A method of equating the forces present within the flow to those experienced by a single molecule within the fluid continuum are also presented.
Principal component analysis of turn-initial words in spoken interactions

The present study investigates turn-initial words in spoken interactions by using principal component analysis. The choice of turn initiators differs significantly in different settings. In formal settings like White House press conferences, the first person pronouns I and we are characteristically employed at the very beginning of utterances, while this tendency is not observed in less formal and more conversational settings. Other initiators relatively frequent in formal settings include: well, the, and no. Furthermore, our findings suggest that female speakers are inclined to link their utterances to previous speakers’ turns by using interpersonal initiators like vocative personal names (e.g. John, Gary, and David). On the whole, however, the factor of gender is much less significant than the factor of the setting.
Antifungal activity of raw extract and flavanons isolated from Piper ecuadorense from Ecuador

The MeOH extract of Piper ecuadorense Sodiro, Piperaceae, was chosen for metabolite isolation and elucidation due to the strong antifungal activity exhibited, measured by means of the broth microdilution method. Two known flavonoids: pinostrobin (1) and pinocembrin (2) were isolated from 4.16 g. of dichloromethane extract by column chromatography, using a gradient of hexane/EtOAc. A total of 20 mg of 1 were obtained from the fraction eluted with hexane-EtOAc 95:5 v/v, and 100 mg of 2 were obtained from the fraction eluted with hexane-EtOAc 85:15 v/v. The MIC values of the MeOH extract was 31.25 µg/mL for Trichophyton mentagrophytes ATCC® 28185 and 62.5 µg/mL for Trichophyton rubrum ATCC® 28188. The MIC value of pinocembrin was 125 µg/mL for Trichophyton mentagrophytes ATCC® 28185 and Trichophyton rubrum ATCC® 28188. Pinostrobin in antifungal test was not active against fungi tested.
Computerized Cognitive Testing for Older Adults

Objective: This article is a review of computerized tests and batteries used in the cognitive assessment of older adults. Method: A literature search on Medline followed by cross-referencing yielded a total of 76 citations. Results: Seventeen test batteries were identified and categorized according to their scope. Computerized adaptive testing (CAT) and the Cambridge Cognitive Examination CAT battery as well as 3 experimental batteries and an experimental test are discussed in separate sections. All batteries exhibit strengths associated with computerized testing such as standardization of administration, accurate measurement of many variables, automated record keeping, and savings of time and costs. Discriminant validity and test–retest reliability were well documented for most batteries while documentation of other psychometric properties varied. Conclusion: The large number of available batteries can be beneficial to the clinician or researcher; however, care should be taken in order to choose the correct battery for each application.
Reproductive characteristics and obesity in middle-aged women seen at an outpatient clinic in southern Brazil

Objective The objective of this study was to investigate the association between reproductive events and abdominal obesity (waist circumference, ≥88 cm) and general obesity (body mass index, ≥30.0 kg/m2) in a sample of women between the ages of 40 and 65 years treated at an outpatient clinic in southern Brazil. Methods This was a cross-sectional study of a sample of 617 women from southern Brazil. Menopause status was classified as premenopausal, women who had regular menstrual cycles; perimenopausal, women who had irregular menstrual cycles whether in periodicity or flow; or postmenopausal, women whose last menstrual period occurred more than 12 months before the time of interview. Poisson regression was used to calculate crude and adjusted prevalence ratios and their respective 95% CIs. Results The prevalence rates of abdominal and general obesity were 66.6% (95% CI, 62.8%-70.3%) and 45.5% (95% CI, 41.5%-9.4%), respectively. After adjustment for demographic, socioeconomic, and behavioral variables, early menarche (⩽11 y) and parity were strong predictors of abdominal and general obesity, presenting a dose-response relationship. Women with a history of three or more pregnancies and menarche at age 11 years or earlier had a 25% higher prevalence of abdominal obesity (95% CI, 1.07-1.46) and a 75% increase in obesity (95% CI, 1.37-2.24) compared with nulliparous or primiparous women with menarche at 14 years or older. Women with a postmenopause status showed an increase of 52% in general obesity, compared with those with a premenopause status. Conclusions Characteristics of reproductive life may have a strong influence on body fat buildup in women during the menopausal transition.
New approach to predict propagation path loss over flat terrains

In this paper, a new approach to predict path loss over flat terrain scenario is presented. The approach uses earth bulge to compute actual transmission (service) range in terms of geometric range to the horizon. Path loss is computed for this actual range by using Fresnel-Kirchhoffs Knife Edge diffraction theory. The results obtained by applying this approach is compared with the results of path loss obtained using geometric range and the corresponding path loss measurement for the given terrain scenarios (horizon). The comparison of results shows improvement over geometric range.
Converging safety and high-performance domains: Integrating OpenMP into Ada

The use of parallel heterogeneous embedded architectures is needed to implement the level of performance required in advanced safety-critical systems. Hence, there is a demand for using high level parallel programming models capable of efficiently exploiting the performance opportunities. In this paper, we evaluate the incorporation of OpenMP, a parallel programming model used in HPC, into Ada, a language spread in safety-critical domains. We demonstrate that the execution model of OpenMP is compatible with the recently proposed Ada tasklet model, meant to exploit fine-grain structured parallelism. Moreover, we show the compatibility of the OpenMP and tasklet models, enabling the use of OpenMP directives in Ada to further exploit unstructured parallelism and heterogeneous computation. Finally, we state the safety properties of OpenMP and analyze the interoperability between the OpenMP and Ada runtimes. Overall, we conclude that OpenMP can be effectively incorporated into Ada without jeopardizing its safety properties.
Development and implementation of a novel immune thrombocytopenia bleeding score for dogs

Background A method of quantifying clinical bleeding in dogs with immune thrombocytopenia (ITP) is needed because ITP patients have variable bleeding tendencies that inconsistently correlate with platelet count. A scoring system will facilitate patient comparisons and allow stratification based on bleeding severity in clinical trials. Hypothesis/Objectives To develop and evaluate a bleeding assessment tool for dogs, and a training course for improving its consistent implementation. Animals Client‐owned dogs (n = 61) with platelet counts <50,000/μL; 34 classified as primary ITP, 17 as secondary ITP, and 10 as non‐ITP. Methods A novel bleeding assessment tool, DOGiBAT, comprising bleeding grades from 0 (none) to 2 (severe) at 9 anatomic sites, was developed. Clinicians and technicians completed a training course and quiz before scoring thrombocytopenic patients. The training course was assessed by randomizing student volunteers to take the quiz with or without prior training. A logistic regression model assessed the association between training and quiz performance. The correlation of DOGiBAT score with platelet count and outcome measures was assessed in the thrombocytopenic dogs. Results Clinicians and technicians consistently applied the DOGiBAT, correctly scoring all quiz cases. The odds of trained students answering correctly were higher than those of untrained students (P < .0001). In clinical cases, DOGiBAT score and platelet count were inversely correlated (r s = −0.527, P < .0001), and DOGiBAT directly correlated with transfusion requirements (r s = 0.512, P < .0001) and hospitalization duration (r s = 0.35, P = .006). Conclusions and Clinical Importance The DOGiBAT and assessment quiz are simple tools to standardize evaluation of bleeding severity. With further validation, the DOGiBAT may provide a clinically relevant metric to characterize ITP severity and monitor response in treatment trials.
