In this review we aim to provide an overview of the most important ethical pros and cons of stem cell derived gametes (SCD-gametes), as a contribution to the debate about reproductive tissue engineering. Derivation of gametes from stem cells holds promising applications both for research and for clinical use in assisted reproduction. We explore the ethical issues connected to gametes derived from embryonic stem cells (both patient specific and non-patient specific) as well as those related to gametes derived from induced pluripotent stem cells...

Ice residual (IR) and total aerosol properties were measured in mixed-phase clouds (MPCs) at the high-alpine Jungfraujoch research station. Black carbon (BC) content and coating thickness of BC-containing particles were determined using single-particle soot photometers. The ice activated fraction (IAF), derived from a comparison of IR and total aerosol particle size distributions, showed an enrichment of large particles in the IR, with an increase in the IAF from values on the order of 10(-4) to 10(-3) for 100 nm (diameter) particles to 0...

The UK Defence Medical Service's Pre-Hospital Emergency Care (PHEC) capability includes rapid-deployment Medical Emergency Response Teams (MERTs) comprising tri-service trauma consultants, paramedics and specialised nurses, all of whom are qualified to administer emergency care under extreme conditions to improve the survival prospects of combat casualties. The pre-deployment training of MERT personnel is designed to foster individual knowledge, skills and abilities in PHEC and in small team performance and cohesion in 'mission-specific' contexts...

The scientific research papers by Professor John William Gorrod who died in December 2015 are reviewed. He was one of the most important scientists in the area and investigated mainly the biological oxidation of nitrogen containing drugs and xenobiotics. In this review, more than 200 papers belong to him are evaluated, most of which involved the results from in vitro microsomal oxidative metabolism of nitrogen containing xenobiotics. These studies include the carcinogenicity of tobacco smoke constituents, aromatic amines, aminophenols, rubber and aminobiphenyls, the assay for ferriheamoglobinemia forming compounds, metabolism of aralkyl azo compounds, aromatic amines, aromatic azaheterocycles, synthesis of N-oxidative metabolites i...

PURPOSE: Treating nose skin with an electron beam is of a substantial challenge due to uneven nose surfaces and tissue heterogeneity, and consequently could have a great uncertainty of dose accuracy on the target. This work explored the method using Monte Carlo (MC)-based energy and intensity modulated electron radiotherapy (MERT), which would be delivered with a photon MLC in a standard medical linac (Artiste). METHODS: The traditional treatment on the nose skin involves the usage of a bolus, often with a single energy electron beam...

PURPOSE: To estimate the dosimetric potential of mixed beam radiotherapy (MBRT) by using a single process optimizing the shape and weight of photon and electron apertures simultaneously based on Monte Carlo beamlet dose distributions. METHODS: A simulated annealing based direct aperture optimization capable to perform simultaneous optimization was developed to generate treatment plans for MERT, photon-IMRT and MBRT. Both photon and electron apertures are collimated with the photon-MLC and are delivered in a segmented manner...

Velopharyngeal insufficiency (VPI) is certainly one of the most important problems confronted after cleft palate repairs. In this study, it was aimed to evaluate the preoperative and postoperative speaking results of patients who underwent modified superior-based pharyngeal flap. Sixty-six children who underwent modified superiorly based pharyngeal flap for treatment of VPI between 2005 and 2013 were retrospectively reviewed. The study population was evaluated in 2 distinctive groups depending on their preoperative velopharyngeal closure pattern as: coronal closure pattern or noncoronal closure patterns (ie, circular, sagittal with or without the presence of a Passavant ridge)...

AIM: To examine the variables associated with mortality in patients with Acinetobacter baumannii-related central nervous system infections treated with intrathecal colistin. MATERIALS AND METHODS: This multi-centre retrospective case control study included patients from 11 centres in Turkey, as well as cases found during a literature review.

The aim of this study was to investigate the criteria used to distinguish coagulase-negative staphylococci (CoNS) bacteremia from contamination. We evaluated 162 adult patients with CoNS-positive blood cultures (BCs). Of the 162 patients, 35 (21.6%) had at least 2 positive BCs and 127 (78.4%) had a single positive BC. According to the Laboratory-Confirmed Bloodstream Infection (LCBI) criteria, 24 (14.8%) patients with the same species of CoNS had true bacteremia, and 138 (85.2%) patients had contaminants. Despite the detection of the same CoNS species, 9 of the 24 patients had different CoNS genotypes...

SPECIES is an undulator-based soft X-ray beamline that replaced the old I511 beamline at the MAX II storage ring. SPECIES is aimed at high-resolution ambient-pressure X-ray photoelectron spectroscopy (APXPS), near-edge X-ray absorption fine-structure (NEXAFS), X-ray emission spectroscopy (XES) and resonant inelastic X-ray scattering (RIXS) experiments. The beamline has two branches that use a common elliptically polarizing undulator and monochromator. The beam is switched between the two branches by changing the focusing optics after the monochromator...

A systematic study has been carried out to compare the surface morphology, shell thickness, mechanical properties, and binding behavior of melamine-formaldehyde microcapsules of 5-30 μm diameter size with various amounts of core content by using scanning and transmission electron microscopy including electron tomography, in situ nanomechanical tensile testing, and electron energy-loss spectroscopy. It is found that porosities are present on the outside surface of the capsule shell, but not on the inner surface of the shell...

STUDY DESIGN: Retrospective diagnostic study. PURPOSE: To define a new radiological sign, "Baltalimani sign," in severe angular kyphosis (SAK) and to report its relationship with the risk of neurological deficits and deformity severity. OVERVIEW OF LITERATURE: Baltalimani sign was previously undefined in the literature. METHODS: We propose Baltalimani sign as the axial orientation of the vertebrae that are located above or below the apex of angular kyphosis on anteroposterior radiographs...

Introduction. Extracorporeal circulation (ECC) related systemic oxidative stress is a well-known entity but the underlying mechanisms are not clearly described. Our aim was to investigate the relation between the oxidative stress indices, inflammatory markers, and phosphorylcholine-coated (PCC) ECC systems. Patients and Methods. Thirty-two consecutive coronary artery bypass grafting (CABG) cases were randomly assigned to Group I (PCC, n = 18) and Group II (noncoated, n = 14) ECC circuits. Total Antioxidant Status (TAS), Total Oxidant Status (TOS), Tumor Necrosis Factor-α (TNF-α), Interleukin-1β (IL-β), Interleukin-6 (IL-6), Interleukin-8 (IL-8), Interleukin-10 (IL-10), and Procalcitonin (PCT) levels were measured at 5 different time points...

MDH2 encodes mitochondrial malate dehydrogenase (MDH), which is essential for the conversion of malate to oxaloacetate as part of the proper functioning of the Krebs cycle. We report bi-allelic pathogenic mutations in MDH2 in three unrelated subjects presenting with early-onset generalized hypotonia, psychomotor delay, refractory epilepsy, and elevated lactate in the blood and cerebrospinal fluid. Functional studies in fibroblasts from affected subjects showed both an apparently complete loss of MDH2 levels and MDH2 enzymatic activity close to null...

OBJECTIVES: This study aims to classify the factors that make rhinoplasty difficult and appropriate reconstruction of it. PATIENTS AND METHODS: We retrospectively evaluated the records of 103 patients who underwent rhinoplasty at our private clinic between April 2002 and December 2014. The most important reagent affecting the degree of difficulty in our study was the adhesion of the bone and cartilaginous structures to the skin and mucosa, as an outcome of on previous operations...
