This study reports findings of an unusual cluster of mutations spanning 22 base pairs in a monoclonal antibody (mAb) expression vector. It was identified by two orthogonal methods: mass spectrometry on expressed protein and next-generation sequencing (NGS) on the plasmid DNA. While the initial NGS analysis confirmed the designed sequence modification, intact mass analysis detected an additional mass of the antibody molecule expressed in CHO cells. The extra mass was eventually found to be associated with unmatched nucleotides in a distal region by checking full-length sequence alignment plots...

In Hamburg, Germany, the initiation of HIV post-exposure prophylaxis (HIV PEP) in cases of sexual violence is often carried out by forensic medical specialists (FMS) using the city's unique Hamburg Model. FMS-provided three-day HIV PEP starter packs include a combination of raltegravir and emtricitabine/tenofovir. This study aimed to investigate the practice of offering HIV PEP, reasons for discontinuing treatment, patient compliance, and whether or not potential perpetrators were tested for HIV. We conducted a retrospective study of forensic clinical examinations carried out by the Hamburg Department of Legal Medicine following incidents of sexual violence from 2009 to 2016...

REVIEW
Dianne J Crellin, Franz E Babl, Nick Santamaria, Denise Harrison
PROBLEM: Clinicians and researchers require a valid way to assess procedural pain experienced by infants and children. The Modified Behavioral Pain Scale (MBPS) has been used to assess immunisation pain. However, it is unknown whether it is valid for this purpose and whether use can be extended to other procedures. The aim of this study was to rigorously assess evidence addressing the psychometric properties of this scale and to provide recommendations for its use. ELIGIBILITY CRITERIA: Psychometric evaluation studies reporting feasibility, reliability, validity, or utility data for the MBPS applied to children (birth to 18years) and randomised controlled trials (RCT) using the MBPS were included...

BACKGROUND: Physical inactivity is associated with excess weight and adverse health outcomes. We synthesize the evidence on physical inactivity and its social determinants in Arab countries, with special attention to gender and cultural context. METHODS: We searched MEDLINE, Popline, and SSCI for articles published between 2000 and 2016, assessing the prevalence of physical inactivity and its social determinants. We also included national survey reports on physical activity, and searched for analyses of the social context of physical activity...

AIMS AND OBJECTIVES: To examine barriers of advance care planning (ACP) experienced by care managers (CMs) through a mixed methods approach. A concurrent nested design was used to acquire a deeper understanding of ACP, and to identify nuances between quantitative and qualitative data. BACKGROUND: Past quantitative studies on providers have identified barriers related to time, culture, knowledge, responsibility, and availability of legal documents. These barriers, and accompanying attitudes and feelings, have been taken at face value without rich qualitative data to identify under what conditions and to what extent a barrier impacts care...

In healthy buildings, it is considered essential to quantify air quality. One of the most fashionable indicators is radon gas. To determine the presence of this element, which is harmful to health, in the environment, the composition of the soil is studied. The presence of radon gas within a building depends both on the terrain in which it is located and on the composition of the materials of which it is composed, and not as was previously believed, only by the composition of the soil (whether granitic or not)...

Chemisorption of hydrogen on metallic particles is often used to estimate the metal dispersion ( D ), the metal particle size ( d ), and the metallic specific surface area ( SM ), currently assuming a stoichiometry of one hydrogen atom H adsorbed per surface metal atom M . This assumption leads to a large error when estimating D , d , and SM , and a rigorous method is needed to tackle this problem. A model describing the statistics of the metal surface atom and site distribution on perfect cuboctahedron clusters, already developed for Pt, is applied to Pd, Ir, and Rh, using the density functional theory (DFT) calculation of the literature to determine the most favorable adsorption sites for each metal...

A general, transparent, finite-strain Integrated Digital Image Correlation (IDIC) framework for high angular resolution EBSD (HR-EBSD) is proposed, and implemented through a rigorous derivation of the optimization scheme starting from the fundamental brightness conservation equation in combination with a clear geometric model of the Electron BackScatter Pattern (EBSP) formation. This results in a direct one-step correlation of the full field-of-view of EBSPs, which is validated here on dynamically simulated patterns...

The year 2018 marks the 150th anniversary of the first publication of Julius von Sachs' (1832-1897) Lehrbuch der Botanik (Textbook of Botany), which provided a comprehensive summary of what was then known about the plant sciences. Three years earlier, in 1865, Sachs produced the equally impressive Handbuch der Experimental-Physiologie der Pflanzen (Handbook of Experimental Plant Physiology), which summarized the state of knowledge in all aspects of the discipline known today as plant physiology. Both of these books provided numerous insights based on Sachs' seminal experiments...

One of the most fundamental principles of patient safety is to investigate and learn from the past in order to improve the future. However, healthcare organizations can find it challenging to develop the robust organizational processes and work practices that are needed to rigorously investigate and learn from safety incidents. Key challenges include difficulties developing specialist knowledge and expertise, understanding complex incidents, coordinating collaborative action, and positively changing practice...

Weinan Gao, Zhong-Ping Jiang
This paper proposes a novel data-driven control approach to address the problem of adaptive optimal tracking for a class of nonlinear systems taking the strict-feedback form. Adaptive dynamic programming (ADP) and nonlinear output regulation theories are integrated for the first time to compute an adaptive near-optimal tracker without any a priori knowledge of the system dynamics. Fundamentally different from adaptive optimal stabilization problems, the solution to a Hamilton-Jacobi-Bellman (HJB) equation, not necessarily a positive definite function, cannot be approximated through the existing iterative methods...

Prediction of membrane permeability to small molecules represents an important aspect of drug discovery. First-principle calculations of this quantity require an accurate description of both the thermodynamics and kinetics that underlie translocation of the permeant across the lipid bilayer. In this contribution, the membrane permeability to three drugs, or drug-like molecules, namely, 9-anthroic acid (ANA), 2',3'-dideoxyadenosine (DDA) and hydrocortisone (HYL) are estimated in a pure 1-palmitoyl-2-oleoyl-phosphatidylcholine (POPC) and in a POPC:cholesterol (2:1) mixture...

BACKGROUND: Insufficient consumption of fruits and vegetables in childhood increases the risk of future non-communicable diseases, including cardiovascular disease. Interventions to increase consumption of fruit and vegetables, such as those focused on specific child-feeding strategies and parent nutrition education interventions in early childhood may therefore be an effective strategy in reducing this disease burden. OBJECTIVES: To assess the effectiveness, cost effectiveness and associated adverse events of interventions designed to increase the consumption of fruit, vegetables or both amongst children aged five years and under...

The rat cardiomyoblast cell line H9C2 has emerged as a valuable tool for studying cardiac development, mechanisms of disease and toxicology. We present here a rigorous proteomic analysis that monitored the changes in protein expression during differentiation of H9C2 cells into cardiomyocyte-like cells over time. Quantitative mass spectrometry followed by gene ontology (GO) enrichment analysis revealed that early changes in H9C2 differentiation are related to protein pathways of cardiac muscle morphogenesis and sphingolipid synthesis...
