BACKGROUND: Complement may play a key role in antibody-mediated rejection. A promising therapeutic approach may be classical pathway (CP) inhibition at the level of early component C1. METHODS: In this first-in-human, double-blind, randomized placebo-controlled phase 1 trial, we evaluated the safety and complement inhibitory effect of TNT009, a humanized monoclonal anti-C1s antibody. Sixty-four adult healthy volunteers received either single (n = 48; 7 consecutive cohorts, 0...

OBJECTIVE: Non-Hodgkin's lymphoma (NHL) remains among the most frequent malignancies in persons living with HIV (PLWHIV). Survival among patients with HIV-associated diffuse large B-cell lymphoma (DLBCL), the most frequent NHL subtype, has improved markedly in recent years. We aimed to analyze characteristics and outcomes of DLBCL in HIV-infected patients in the era of modern combined antiretroviral therapy (cART). DESIGN: PLWHIV with lymphoma were prospectively enrolled in the French ANRS-CO16 Lymphovir cohort between 2008 and 2015...

Invasive coronary angiography (ICA) with measurement of fractional flow reserve (FFR) by means of a pressure wire technique is the established reference standard for the functional assessment of coronary artery disease (CAD) ( 1 , 2 ). Coronary computed tomographic (CT) angiography has emerged as a noninvasive method for direct assessment of CAD and plaque characterization with high diagnostic accuracy compared with ICA ( 3 , 4 ). However, the solely anatomic assessment provided with both coronary CT angiography and ICA has poor discriminatory power for ischemia-inducing lesions...

The specific recognition of protein surface elements is a fundamental challenge in the life sciences. New developments in this field will form the basis of new therapeutic approaches and will lead to applications such as sensors, affinity-tags, immobilization techniques and protein-based materials. Synthetic supramolecular molecules and materials are creating new opportunities for protein recognition, which are orthogonal to classical small molecule and protein-based approaches. As outlined here, their unique molecular features enable the recognition of amino acids, peptides and even whole protein surfaces, which can be applied to the modulation and assembly of proteins...

Surgical site infections (SSIs) are one of the most common nosocomial infections, which can result in serious complications after surgical interventions. Foreign materials such as implants or surgical sutures are optimal surfaces for the adherence of bacteria and subsequent colonization and biofilm formation. Due to a significant increase in antibiotic-resistant bacterial strains, naturally occurring agents exhibiting antibacterial properties have great potential in prophylactic therapies. The aim of this study was to develop a coating for surgical sutures consisting of the antibacterial substance totarol, a naturally occurring diterpenoid isolated from Podocarpustotara in combination with poly(lactide-co-glycolide acid) (PLGA) as a biodegradable drug delivery system...

Videos are often employed in medical cursus, yet few guidelines are available to help with their production. Mayer's cognitive theory of multimedia learning is the most cited evidence-based framework for improving pedagogical effectiveness of multimedia content. Based on this framework, we identified four workflow interventions to improve the effectiveness of video content in the context of medical education: (1) choosing appropriate content; (2) optimizing the voiceover; (3) optimizing the supporting visuals and (4) planning the shooting schedule in advance...

Retinal gene delivery via intravitreal injection is hampered by various physiological barriers present in the eye of which the vitreoretinal (VR) interface represents the most serious hurdle. In this study, we present a retinal explant model especially designed to study the role of this interface as a barrier for the penetration of vectors into the retina. In contrast to all existing explant models, the developed model is bovine-derived and more importantly, keeps the vitreous attached to the retina at all times to guarantee an intact VR interface...

Tip-enhanced Raman spectroscopy (TERS) has been rapidly improved over the last decade and opened up opportunities to study phonon properties of materials at the nanometer scale. In this contribution we report on tip-enhanced Raman spectroscopy (TERS) of an ultra-thin MoS2 flake on a nanostructured Au on silicon surface forming a two-dimensional (2D) crystal/plasmonic heterostructure. Au nanostructures (shaped in triangles) are prepared by nanosphere lithography and then MoS2 is mechanically exfoliated on top of them...

BACKGROUND: Non-HLA-antibodies against human endothelial progenitor cells (EPC) in pre-transplant recipient serum can have a deleterious influence on the graft. EPC enriched from peripheral blood have been commonly used for EPC crossmatching. In the present study, we describe crossmatches using EPC enriched from fresh or frozen-thawed spleen cell preparations, thereby widening the sample source for deceased-donor crossmatching and retrospective studies. METHODS: EPC crossmatches were performed retrospectively using spleen cells and the flow cytometric XM-ONE crossmatch test kit...

The natural habitats and potential reservoirs of the nosocomial pathogen Acinetobacter baumannii are poorly defined. Here, we put forth and tested the hypothesis of avian reservoirs of A. baumannii. We screened tracheal and rectal swab samples from livestock (chicken, geese) and wild birds (white stork nestlings) and isolated A. baumannii from 3% of sampled chicken (n=220), 8% of geese (n=40) and 25% of white stork nestlings (n=661). Virulence of selected avian A. baumannii isolates was comparable to that of clinical isolates in the Galleria mellonella infection model...

OBJECTIVES: Dental diseases are the most common chronic diseases worldwide. Healthy teeth are vital for quality of life, particularly diet and nutrition. However, little information exists to inform health policymakers about potentially long-lasting influences of early-life conditions. The purpose of this study was to investigate the relation between early-life socioeconomic conditions and number of natural teeth at age 50 and above. METHODS: Analyses were conducted on cross-sectional data from the Survey of Health, Ageing and Retirement in Europe (SHARE wave 5), which includes information on 41 560 respondents aged 50 years or older from 14 European countries and Israel...

Ricin is one of the most feared bioweapons in the world due to its extreme toxicity and easy access. Since no antidote exists, it is of paramount importance to identify the pathways underlying ricin toxicity. Here, we demonstrate that the Golgi GDP-fucose transporter Slc35c1 and fucosyltransferase Fut9 are key regulators of ricin toxicity. Genetic and pharmacological inhibition of fucosylation renders diverse cell types resistant to ricin via deregulated intracellular trafficking. Importantly, cells from a patient with SLC35C1 deficiency are also resistant to ricin...

Melting glaciers release previously ice-entrapped chemicals to the surrounding environment. As glacier melting accelerates under future climate warming, chemical release may also increase. This study investigated the behavior of semi-volatile pesticides over the course of one year and predicted their behavior under two future climate change scenarios. Pesticides were quantified in air, lake water, glacial melt water, and stream water in the catchment of Lake Brewster, an alpine glacier-fed lake located in the Southern Alps of New Zealand...

Nonadherence to treatment is a major cause of lupus flares. Hydroxychloroquine (HCQ), a major medication in systemic lupus erythematosus, has a long half-life and can be quantified by HPLC. This international study evaluated nonadherence in 305 lupus patients with flares using drug levels (HCQ<200ng/ml or undetectable desethylchloroquine), and self-administered questionnaires (MASRI<80% or MMAS-8<6). Drug levels defined 18.4% of the patients as severely nonadherent. In multivariate analyses, younger age, non-use of steroids, higher BMI and unemployment were associated with nonadherence by drug level...

Chronic urticaria (CU) is a group of common and debilitating conditions containing both chronic spontaneous urticaria (CSU) and chronic inducible urticarias (CIndU) including cold urticaria (ColdU) [1]. While antihistamines and omalizumab are effective treatments for both CSU and ColdU [2], many patients show insufficient response to either or both of these treatments [3], and additional and better therapies are needed [4].

BACKGROUND: Estrogen signalling is transmitted via various receptors and multiple intracellular signalling pathways. Estrogen receptor alpha (ERα)-mediated transcription of target genes has been demonstrated to be closely linked to human papilloma virus (HPV)-induced carcinogenesis in case of cervical cancer. So far, the role of non-genomic estrogen signals in cervical cancer, e.g. transmitted by the G protein-coupled estrogen receptor (GPER) remains to be rather elusive. Today's knowledge on the role of GPER in cervical cancer is sparse and-to the best of our knowledge-GPER has not been investigated in context with clinicopathological parameters or prognosis of cervical cancer...

BACKGROUND: Bipolar vessel sealing has been successfully introduced in a variety of procedures like prostatectomy, hysterectomy, and nephrectomy. In this study, we evaluated a new sealing mode-the thermoSEAL(®) mode (TSM)-operated with the VIO3 generator in an ex vivo and in vivo animal study and compared the results with the commercially available BiClamp mode (BCM), operated with the VIO300D generator. Two different instruments were used in combination with both modes, BiCision(®) and BiClamp(®) 201T (Erbe Elektromedizin GmbH)...
