Safety, immunogenicity, pharmacokinetics and efficacy of the immunoglobulin G-degrading enzyme of Streptococcus pyogenes (IdeS, Imlifidase) was assessed in a single centre, open label ascending dose study in highly sensitised chronic kidney disease patients. Eight patients with cytotoxic panel-reactive antibodies (median cytotoxic PRA of 64%) at enrolment received 1 or 2 intravenous infusions of IdeS on consecutive days (0.12 mg/kg body weight x2 (n=3); 0.25 mg/kg x1 (n=3) or 0.25 mg/kg x2 (n=2)). IgG degradation was observed in all subjects after IdeS treatment, with <1% plasma IgG remaining within 48 hours and remaining low up to 7 days...

BACKGROUND: Cardiovascular disease (CVD) is a leading cause of post-liver transplant death, and variable care patterns may affect outcomes. We aimed to describe epidemiology and outcomes of inpatient CVD care across U.S. hospitals. METHODS: Using a merged dataset from the 2002-2011 Nationwide Inpatient Sample and the American Hospital Association Annual Survey, we evaluated liver transplant patients admitted primarily with myocardial infarction (MI), stroke (CVA), congestive heart failure (CHF), dysrhythmias, cardiac arrest (CA), or malignant hypertension...

We have used an unbiased statistical approach to compare the pace of development in the main and accessory olfactory systems in monotremes and metatherians with that in rodents and humans. We hypothesized that if metatherians and monotremes, which are born at small body size, use olfaction to locate the pouch and/or teat/milk field, then olfactory structures should reach structural maturity in metatherians and monotremes at a smaller size than eutherians like humans and rodents. The achievement of key structural milestones in the development of the main and accessory olfactory systems (11 and 7 milestones, respectively) was scored for 354 specimens and compared against a measure of general somatic growth (body length)...

Type 2 diabetes mellitus is characterized by the loss of ß-cell function and mass, resulting from interactions between genetic predisposition and various environmental factors1 . One environmental condition identified as a risk factor for type 2 diabetes mellitus is circadian rhythm disruption, which is induced by shift work or sleep disturbance. However, the mechanism whereby circadian disruption leads to impaired glucose metabolism is not well understood. This article is protected by copyright. All rights reserved...

Alveolar type II cells from seven mammalian species were examined for a protein in the rough endoplasmic reticulum (RER), which showed a multi-layered, repeating motif. Each motif, 100nm in width, comprised two parallel outer dense layers, a less dense central layer, and often 1-3 faint layers on either side of the latter. Outer layers showed periodicities at 3-4 densities/100nm of width, while layers on either side of the central layer showed 5-7 densities/100nm of width. RER membranes were ribosome-free when parallel to these layers, but showed 4 ribosomes per motif at the growing ends: one ribosome at each outer dense layer, and one on either side of the less dense central layer...

The existence of sex differences in digit-length ratio (especially between the second and fourth digits, 2D:4D) is well established for humans from fetal life onwards, and has been linked with later performance. In rodents, the ratio is affected prenatally by exposure to androgens and estrogens, with some research suggesting an influence from sex of the neighbouring intrauterine fetus. However, the ubiquity and ontogenetic development of sexual dimorphism in digit ratios is not well established among wild amniotes...

Histone deacetylase 4 (Hdac4) is known to control chondrocyte hypertrophy and bone formation. We have previously shown that parathyroid hormone (PTH) regulates many aspects of Hdac4 function in osteoblastic cells in vitro; however, in vivo confirmation was previously precluded by pre-weaning lethality of the Hdac4 deficient mice. To analyze the function of Hdac4 in bone in mature animals, we generated mice with osteoblast lineage-specific knockout of Hdac4 (Hdac4ob-/- ) by crossing transgenic mice expressing Cre recombinase under the control of a 2...

With population aging, prevalence of low bone mineral density (BMD) and associated fracture risk are increased. To determine whether low circulating thyroid stimulating hormone (TSH) levels within the normal range are causally related to BMD, we conducted a two-sample Mendelian randomization (MR) study. Furthermore, we tested whether common genetic variants in the TSH receptor (TSHR) gene and genetic variants influencing expression of TSHR (eQTLs) are associated with BMD. For both analyses, we used summary-level data of genome-wide association studies (GWAS) investigating BMD of the femoral neck (N = 32,735) and the lumbar spine (N = 28,498) in cohorts of European ancestry from the Genetic Factors of Osteoporosis (GEFOS) Consortium...

Osteogenesis imperfecta (OI) is a genetic disorder characterized by altered bone quality and imbalanced bone remodeling, leading to skeletal fractures which are most prominent during childhood. Treatments for OI have focused on restoring pediatric bone density and architecture to recover functional strength and consequently reduce fragility. Though antiresorptive agents like bisphosphonates (BP) are currently the most common intervention for the treatment of OI, a number of studies have shown efficacy of sclerostin antibody (SclAb) in inducing gains in bone mass and reducing fragility in OI mouse models...

According to the American Association for the Study of Liver Disease treatment guidelines for hepatocellular carcinoma (HCC), the role of surgery has been expanded beyond the Barcelona Clinic Liver Cancer (BCLC) algorithm. We compared primary hepatectomy (PH) with transarterial chemoembolization (TACE) in patients with intermediate to advanced (BCLC stage-B/C) stage HCC to determine the current evidence. Through database search, we included 18 high-quality studies (1 randomized controlled trial [RCT], 5 propensity-score matching non-randomized comparative trials [NRCT], and 12 NRCTs) that compared survival outcomes of 5,986 patients after PH and TACE...

This work presents a simple, low-cost method to fabricate semi-circular channels using solder paste, which can amalgamate the cooper surface to form a half-cylinder mould using the surface tension of Sn-Pd alloy (the main component in solder paste). This technique enables semi-circular channels to be manufactured with different dimensions. These semi-circular channels will then be integrated with a polymethylmethacrylate (PMMA) frame and machine screws to create miniaturised, portable microfluidic valves for sequential liquid delivery and particle synthesis...

INTRODUCTION: For sequential and somatotopic assessment of small fiber neuropathy (SFN), heat pain (HP) tests of hypoalgesia might be used instead of decreased counts of epidermal nerve fibers (ENFs), but then healthy subject reference values of HP thresholds are needed. METHODS: Using the CASE IVc system, HP thresholds of hypoalgesia were estimated for ten unilateral sites and counts of ENFs for four of them in healthy subjects. RESULTS: In healthy subjects, small but statistically significant differences of both HP thresholds of hypoalgesia and counts of ENFs were observed among tested sites...
