The biosynthetic and endocytic pathways of secretory cells are characterized by progressive luminal acidification, a process which is crucial for posttranslational modifications and membrane trafficking. This progressive fall in luminal pH is mainly achieved by the vacuolar-type-H+ ATPase (V-ATPase). V-ATPases are large, evolutionarily ancient rotary proton pumps that consist of a peripheral V1 complex, which hydrolyzes ATP, and an integral membrane V0 complex, which transports protons from the cytosol into the lumen...

Lateral ankle sprains are one of the most common injuries in sports. Recently, arthroscopic lateral ligament reconstruction has been recently advocated, however no biomechanical studies and clinical application of this technique are available. In this biomechanical study, eighteen fresh-frozen cadaveric ankles were randomized into three groups: (1) intact anterior talofibular ligament (ATFL) and calcaneofibular ligament (CFL), (2) arthroscopic anatomic reconstruction of ATFL and CFL, and (3) all arthroscopic remnant-preserving reconstruction of ATFL and CFL...

Relation extraction is an important task in the field of natural language processing. In this paper, we describe our approach for the BioCreative VI Task 5: text mining chemical-protein interactions. We investigate multiple deep neural network (DNN) models, including convolutional neural networks, recurrent neural networks (RNNs) and attention-based (ATT-) RNNs (ATT-RNNs) to extract chemical-protein relations. Our experimental results indicate that ATT-RNN models outperform the same models without using attention and the ATT-gated recurrent unit (ATT-GRU) achieves the best performing micro average F1 score of 0...

The Attention Training Technique (ATT) was developed with the aim of reducing self-focused attention and increasing executive control as part of metacognitive therapy. So far there is a paucity of data on the neurophysiological effects of ATT. In the present study we tested for specific effects to determine if attention control components of ATT elicit a specific signature that is different from passive listening. Thirty-six healthy volunteers were randomized to an active (follow instructions) or control (ignore instructions) condition...

Tuberculous mastitis (TBM) is relatively rare disease with an incidence ranging between 0.1 and 4%. Most of the cases are culture negative and often mistaken with chronic benign idiopathic granulomatous mastitis (IGM). It is very crucial to distinguish culture negative TBM from other causes of mastitis as the treatment differs tremendously. We describe here in a young woman originally from India and residing in Qatar; a non endemic area of tuberculosis; for more then fifteen years. She presented with 2 months history of right breast mass, followed by low grade fever, dry cough, headache, erythema nodosum, arthritis, and arthralgia...

Paradoxical reactions (PRs) are exaggerated inflammatory responses owing to recovery of cellular immunity following initiation of anti-tuberculous therapy (ATT). The presentation is worsening of pre-existing symptoms or development of new lesions. A 14-year-old girl with multi-drug-resistant tuberculosis developed a recurrent asymptomatic retropharyngeal abscess while on ATT. She required multiple aspirations of the abscess. Xpert MTB/RIF detected Mycobacterium tuberculosis from the aspirate which was resistant to rifampicin; culture was negative...

OBJECTIVE: The aim was to establish any differences in the predictive value of EEG and MRI for outcome in infants treated and not-treated with therapeutic hypothermia (HT) for perinatal asphyxia. We hypothesize that they are equally predictive and that combining both has the highest predictive value. STUDY DESIGN: We retrospectively compared data of infants with hypoxic-ischemic encephalopathy (HIE) who received HT (n = 45) between September 2009 and December 2013 with those of infants with HIE born between January 2004 and August 2009, before HT was available (NT, n = 37)...

Worldwide occurrence of Methicillin-Resistant Staphylococcus aureus (MRSA) poses enormous challenges for both communities and healthcare settings. Cassette chromosome recombinases (Ccr) specifically exert excision and acquisition of a staphylococcal cassette chromosome mec (SCCmec) in staphylococci and are responsible for the spread of methicillin resistance. This study explored the roles of CcrC2, a recently discovered Ccr, in the horizontal transfer of SCCmec and developed a potential mean to control the spread of methicillin resistance...

Janani Suraksha Yojana (safe motherhood scheme, or JSY) provides cash incentives to marginal pregnant women in India conditional on having mainly institutional delivery. Using the fourth round of district level household survey (DLHS-4), we have estimated its effects on both intended and unintended outcomes. Our estimates of average treatment effect on the treated (ATT) from propensity score matching are remarkably higher than those found in previous prominent studies using the second and third rounds of the survey (DLHS-2 and DLHS-3)...

Propensity score (PS) methods are widely used in observational studies for evaluating marginal treatment effects. PS-weighting is a popular PS-based method that allows for estimating both the average treatment effect on the overall population (ATE) and the average treatment effect on the treated population (ATT). Previous research has shown that the variance of the treatment effect is accurately estimated only if the variance estimator takes into account the fact that the propensity score is itself estimated from the available data in a first step of the analysis...

Management of antithrombotic therapy (ATT) for pediatric ventricular assist devices is challenging, and the Berlin EXCOR remains the only FDA-approved option. Among those on the EXCOR, 28% have neurologic complications and major bleeding occurs in 50%. The Edmonton Protocol was developed to guide ATT, but the adverse event rate remains high, leading most centers to make modifications. The objective of this study is to characterize antithrombotic practice variation among North American pediatric ventricular assist device programs, in order to guide future research...
