Myosin is the principal component of the thick filaments that, through interactions with the actin thin filaments, mediates force production during muscle contraction. Myosin is a hexamer, consisting of two heavy chains, each associated with an essential (ELC) and a regulatory (RLC) light chain, which bind the lever-arm of the heavy chain and play important modulatory roles in striated muscle contraction. Nevertheless, a comprehensive assessment of the sequences of the ELC and RLC isoforms, as well as their post-translational modifications, in the heart remains lacking...

Jann P Foster, Jennifer A Dawson, Peter G Davis, Hannah G Dahlen
BACKGROUND: Oro/nasopharyngeal suction is a method used to clear secretions from the oropharynx and nasopharynx through the application of negative pressure via a suction catheter or bulb syringe. Traditionally, airway oro/nasopharyngeal suction at birth has been used routinely to remove fluid rapidly from the oropharynx and nasopharynx in vigorous and non-vigorous infants at birth. Concerns relating to the reported adverse effects of oro/nasopharyngeal suctioning led to a practice review and routine oro/nasopharyngeal suctioning is no longer recommended for vigorous infants...

PURPOSE: Lacrimo-auriculo-dento-digital (LADD) syndrome is an autosomal dominant disorder displaying variable expression of multiple congenital anomalies including hypoplasia or aplasia of the lacrimal and salivary systems causing abnormal tearing and dry mouth. Mutations in the FGF10, FGFR2, and FGFR3 genes were found to cause some cases of LADD syndrome in prior genetic studies. The goal of this study is to identify the genetic basis of a case of LADD syndrome with glaucoma and thin central corneal thickness (CCT)...

BACKGROUND: Low-dose aspirin protects against ischemic cardiovascular (CV) events as well as colorectal cancer (CRC). However, low-dose aspirin may be associated with a small increased risk of intracranial bleeds (ICB). OBJECTIVES: To obtain incidence rates of ICB overall and by patient subgroups among new users of low-dose aspirin. PATIENTS/METHODS: Using The Health Improvement Network (THIN) UK primary care database (2000-2012), we identified a cohort of new users of low-dose aspirin aged 40-84 years (N=199,079; mean age at start of follow-up, 63...

Converging evidence suggests that the cognitive control processes that enable the inhibition of irrelevant information on a perceptual versus a memorial basis are qualitatively different and are underlain by unique neural systems that may be affected differentially in aging. In the current study, we investigated whether individual differences in performance on these 2 types of inhibitory processes were attributable to region-specific patterns of cortical thinning. Clinically healthy older adults completed a pair of behavioral memory and perceptual inhibition tasks and then underwent structural brain imaging...

Context: Empagliflozin was found to decrease mortality in patients with type 2 diabetes (T2DM) and a prior cardiovascular (CVD) event. Objectives: To establish whether these benefits can be replicated in a real-world setting, should be expected with the use of dapagliflozin, and apply to T2DM patients at low risk of CVD. Design: General Practice, population-based, retrospective cohort study (January 2013-September 2015). Setting: The Health Improvement Network Database (THIN)...

BACKGROUND: There is mixed evidence that older people bereaved of a spouse or partner are at risk of adverse outcomes. The main difficulty is to take account of other explanatory factors. We tested for an association between a patient's death and the timing of any bereavement of a cohabitee. METHOD: Self-controlled case series study in which each case serves as his or her own control and which thereby accounts for all fixed measurable and unmeasurable confounders...

BACKGROUND: Adrenaline auto-injectors (AAI) should be provided to individuals considered to be at high risk of anaphylaxis. There is some evidence that the rate of AAI prescription is increasing, but the true extent has not been previously quantified. AIM: To estimate the trends in annual GP-issued prescriptions for AAI among UK children between 2000 and 2012. DESIGN AND SETTING: Retrospective cohort study using data from primary care practices that contributed to The Health Improvement Network (THIN) database...

INTRODUCTION: The glucagon-like peptide-1 receptor agonists liraglutide and lixisenatide are effective at reducing glycated hemoglobin (HbA1c) levels in patients with type 2 diabetes mellitus (T2DM). Although liraglutide has demonstrated superior efficacy in head-to-head clinical trials, real-world evidence of comparative effectiveness is lacking. This observational study aimed to assess the effectiveness of liraglutide versus lixisenatide in UK clinical practice. METHODS: Electronic medical records from The Health Improvement Network (THIN) UK primary care database were analyzed...

OBJECTIVES: The authors sought to perform a meta-analysis of randomized clinical trials (RCTs) comparing the safety and efficacy of biodegradable polymer drug-eluting stents (BP-DES) to second-generation durable polymer drug-eluting stents (DP-DES). BACKGROUND: Prior meta-analyses have established the superiority of BP-DES over bare-metal stents and first-generation DP-DES; however, their advantage compared with second-generation DP-DES remains controversial. METHODS: The authors searched PubMed and Scopus databases for RCTs comparing BP-DES to the second-generation DP-DES...

Despite emotion researchers' strong interest in empathy and its implications for prosocial functioning, surprisingly few studies have examined parent-child attachment as a context for early origins of empathy in young children. Consequently, empirical evidence on links among children's attachment, empathy, and prosociality is thin and inconsistent. We examined such links in 2 longitudinal studies of community families (Family Study, N = 101 mothers, fathers, and children, 14 to 80 months; Parent-Child Study, mothers and children, N = 108, 15 to 45 months) and a study of low-income, diverse mothers and toddlers (Play Study, N = 186, 30 months)...

OBJECTIVE: To provide an overview of the phenotype of 2 clinically, radiologically, and pathologically similar leukodystrophies, adult-onset leukoencephalopathy with axonal spheroids and pigmented glia (ALSP) and alanyl-transfer RNA synthetase 2 mutation-related leukodystrophy (AARS2-L), and highlight key differentiating features. METHODS: ALSP and AARS2-L cases were identified from the adult-onset leukodystrophy database at our institution. In addition, cases with imaging findings were identified from a literature review...

BACKGROUND AND OBJECTIVES: Standardization of the carotid IMT requires a reference marker in ultrasound scans. It has been shown previously that manual reference marker and manually created carotid segments are used for measuring IMT in these segments. Manual methods are tedious, time consuming, subjective, and prone to errors. Bulb edge can be considered as a reference marker for measurements of the cIMT. However, bulb edge can be difficult to locate in ultrasound scans due to: (a) low signal to noise ratio in the bulb region as compared to common carotid artery region; (b) uncertainty of bulb location in craniocaudal direction; and (c) variability in carotid bulb shape and size...

GATAD2B gene is involved in chromatin modification and transcription activity. Loss-of-function mutations of GATAD2B have recently been defined to cause a recognizable syndrome with intellectual disability (ID). Human TPM3 gene encoding thin filament protein is associated with myopathies. Both genes are located on chromosome 1q21.3. We herein report an infant with feeding difficulty, developmental delay, hypotonia, and dysmorphic features including small palpebral fissures, telecanthus, sparse hair and eyebrow, cup-shaped ears, and clinodactyly...

AIMS: To identify a potential pathogenic isolate of fungus on Convolvulus arvensis and to determine its phytotoxic activity, which revealed the presence of toxic metabolites responsible for the toxicity against the target weed. METHODS AND RESULTS: A high virulent isolate of the fungus, Phoma crystallifera was isolated from symptomatic field bindweed in the west of Iran and was screened for the production of phytotoxins, which promoted necrosis on the detached leaves and seedlings of field bindweed in the bioassays...
