Emissions of volatile and semivolatile organic compounds from various kinds of polymer sheets during thermal degradation process were determined by the passive flux sampling method. Adezmapimod mouse The polymer sheets used were commercial products made of polyethylene (PE), ethylene-vinyl acetate (EVA), polypropylene (PP), polyacetal (POM), polycarbonate (PC)), and polymer sheet samples poly (methyl methacrylate) (PMMA), polyethylene terephthalate (PET), polystyrene (PS) and four types of poly vinyl chloride (PVC) with different contents of additives; (bis(2-ethylhexyl)phthalate (DEHP)), and triphenylphosphine (TPP)). Adezmapimod mouse The emission fluxes from the polymer sheets were measured for up to 30 days stored under a constant temperature (25-75 °C). Emission of various kinds of chemicals were observed from PVC sheets including and products of polymer degradation, while emission of hydrocarbons were dominant from PE, PP and EVA, and the emission of an additive (DEP) only was observed from PMMA, PET, POM and PC. The TVOC (total VOC) emission rates from PVC sheets with DEHP and TPP (soft PVCs) were in the range of 30-120 mg m-2 h-1 at 50 °C, which were much higher than the TVOC emission rates from other polymers. Adezmapimod mouse The emission rates for these chemicals for the same sampling period increased dramatically as the temperature increased. The temperature-dependences of the emission rates from the soft PVC sheet for a given sampling period could be expressed using an Arrhenius-type equation, and the apparent emission activation energy E A , correlated well with the enthalpy of vaporization ΔH VAP by the following empirical equation. link2 E A = 2.27 Δ H vap - 115 We also found that the emission rates of chemicals changed with time with different changing characters, and the activation energy decreased with the progress of the polymer degradation. link2 © 2020 The Authors.Objectives To validate novel non-contacting Confocal-Laser-Scanning-Microscopy (CLSM) methodology with conventional Contacting Profilometry (CP) measures investigating brushing or dab-on of stannous-fluoride dentifrice on early aggressive dentine erosion. Methods 75 polished human dentine samples were prepared and eroded in agitated 6% citric acid then randomly allocated into 5 intervention groups; artificial saliva control (1); controlled use of a pressure sensitive counter-rotating oscillatory powered toothbrush with sodium-fluoride NaF (2) or stannous-fluoride SnF2 (3), and dab-on application of NaF (4) or SnF2 (5). Samples underwent three cycles of intervention and 2-min agitated 6 % citric acid challenges. CLSM images were taken and 3D reconstructions produced of step height using a developed software algorithm. In addition, 20 % samples were randomised and profiled using CP to measure step height and surface roughness. Vickers's diamond micro-hardness testing was carried out on all samples. Results Comp represent dentine step height loss. They show good correlation and agreement with conventional CP measures, following early aggressive erosion-abrasion cycles of dentine. The CLSM and computer algorithm therefore provides an accurate, standalone and non-contacting three-dimensional measurement of early dentine wear. Stannous-fluoride brushing, and dab-on application offer no benefits following early aggressive erosion in dentine. To reduce dentine wear, limiting erosive challenges and avoiding brushing post-erosion is advised. © 2020 Published by Elsevier Ltd.Sleeve gastrectomy is a surgical technique and a leading method in metabolic surgery. Sleeve gastrectomy gained ever-increasing popularity among laparoscopic surgeons involved in bariatric surgery and has proved to be a successful method in achieving considerable weight loss in a short time. There are some disparate effects that patients may experience after sleeve gastrectomy including a reduction in BMI, weight, blood pressure, stroke, and cancer and also a significant remission in obesity-related diseases including type 2 diabetes (T2D), Non-alcoholic fatty liver (NAFLD), cardiovascular disease, obstructive sleep apnea, and craniopharyngioma-related hypothalamic obesity as well as non-obesity-related diseases such as gout, musculoskeletal problems, ovarian disorders and urinary incontinence. The most common complications of sleeve gastrectomy are bleeding, nutrient deficiencies, and leakage. link3 There are several studies on the impact of gender and ethnic disparities on post-operative complications. This study collects state of the art of reports on sleeve gastrectomy. The aim of this study was to analyze recent studies and review the advantages and disadvantages of sleeve gastrectomy. link2 © 2020 Published by Elsevier Ltd.Amoebiasis occurs worldwide and affects about 20-50 million people annually. Stool samples were collected from patients attending different rural clinics in Northern South Africa in the present study. Microscopic examination was performed for the initial detection of Entamoeba parasites. A multiplex PCR protocol based on the small subunit rRNA gene of E. moshkovskii, E. dispar, and E. histolytica, was used for the differential detection of the three Entamoeba species (collectively referred to as Entamoeba complex). A total of 170 participants were recruited in the study, with a mean age of 35.9 ± 17.8 years and a median of 37.0 years. The prevalence of Entamoeba species was found to be 34.7% and 33% by PCR and microscopy, respectively. E. histolytica had a prevalence of 4.1%, E. dispar 14.7% and E. moshkovskii 15.9%. Of the three species, only E. histolytica was significantly associated with diarrhoea and was more prevalent among HIV patients even in the absence of diarrhoea while the other two were not, although the difference was not significant (p > 0.05). This is the first study in South Africa to describe the prevalence of E. moshkovskii. E. dispar was significantly associated with abdominal pains (p = 0.003). Further studies are needed to clarify the role of E. moshkovskii and E. dispar in abdominal pain and diarrhoea. link3 © 2020 The Authors.Foodborne diseases are important everywhere in the world, but the level of attention they receive varies by region. We surveyed the current opinions and knowledge regarding the globally most important foodborne parasites (FBP) among healthcare professionals in Abakaliki, Ebonyi State, Nigeria, by conducting a questionnaire survey among healthcare professionals in a tertiary hospital. We focused on the FBP ranked as the top five globally Taenia solium, Echinococcus granulosus, Echinococcus multilocularis, Toxoplasma gondii, and Cryptosporidium spp., and gathered local expert opinions regarding their importance in Nigeria. Moreover, we surveyed the extent of healthcare community knowledge on transmission, manifestations and pathologies, and prevention of infections with these five FBP. Among the 205 healthcare professionals completing the survey, T. solium was selected as important in Nigeria by 143 (70%), E. granulosus by 91 (44%), E. multilocularis by 62 (30%), T. gondii by 132 (64%), and Cryptosporidium spp. by 123 (60%). Only 44 (21%) of the participants selected at least 15 of the 25 answers to knowledge questions that we considered as correct to select. The proportion selecting at least 15 of the correct answers was not statistically significantly associated with gender nor with experience level. Our results suggest that further education about FBP should target healthcare professionals at all levels. © 2020 The Authors.Sarcocystis spp. link3 are protozoan parasites which can infect a wide range of vertebrates, including humans; the latter can act as definitive hosts for two cattle Sarcocystis spp. Sarcocystis hominis and Sarcocystis heydorni. Reports of intestinal sarcocystosis are well documented in the literature, but PCR-based methods have been scarcely used to identify Sarcocystis species in human stools, and have been limited to the molecular analysis of 18S ribosomal RNA (18S rRNA) gene sequences. Since the mitochondrial cytochrome c oxidase subunit I (COI) gene is one of the most promising tools for distinguishing between closely related Sarcocystis spp., and taking into account the lack of publicly available S. hominis COI sequences, in the present study we obtained the first partial COI sequence of S. hominis from human stool samples of patient with gastrointestinal symptoms. We designed specific COI primers to develop a multiplex PCR method for the identification of Sarcocystis spp. in cattle. The submission of the COI sequence described herein and the unambiguous identification of S. hominis through the application of the new multiplex PCR is important for determining the prevalence of this zoonotic Sarcocystis spp. in meat and the risk for consumers. © 2020 The Authors.We consider the scientific evidence that research on in-vitro development of embryos beyond 14 days is necessary. We then examine potential new developments in the use of stem cells to make embryoids or synthetic human entities with embryo-like features, and consider whether they also require legal control. Next, we consider the arguments advanced against extending the 14-day period during which research on human embryos is currently permitted, and find none of them to be convincing. We end by proposing a new objective limit that could serve as a mechanism for regulating the use of embryos for research in vitro. © 2020 The Authors.Introduction The possibility of intentionally triggering non targeted effects (NTEs) using spatially fractionated radiotherapy (SFRT) alone or combined with immunotherapy is an intriguing and fascinating area of research. Among different techniques for SFRT, stereotactic body radiotherapy targeting exclusively the central hypoxic segment of bulky tumors, (SBRT-PATHY) might trigger immunogenic cell death more efficiently. This in silico study aims to identify the best possible dosimetric trade-off for prescribing SFRT with volumetric modulated arc (VMAT) based stereotactic radiotherapy (SRT). Material and methods Eight spherical volumes defined "Gross Tumor Volumes" (GTVs) were generated with diameters of 3-10 cm (with incremental steps of 1 cm), simulating tumor lesions. The inner third part of each GTV (GTVcentral) was selected to simulate the central hypoxic area and a ring structure was derived around it to simulate the tumor periphery (GTVperipheral). Volumetric modulated arc radiation treatment (VMAT) plans were calculated to deliver a single fraction of 10 Gy to each GTVcentral with different dose prescription methods target mean and isodose driven (40, 50, 60, 70, 80 and 90%).The volume of GTVperipheral receiving less than 2 Gy was recorded as dosimetric performance indicator. Results 56 possible dosimetric scenarios were analyzed. The largest percentage of GTVperipheral spared from the dose of 2 Gy was achieved with dose prescription methods to the 70% isodose line for lesions smaller than 6 cm (range 42.9-48.4%) and to the target mean for larger ones (range 52.9-64.5%). Conclusions Optimizing the dose prescription method may reduce the dose to tumor periphery in VMAT-based SFRT, thus potentially sparing tumor infiltrating immune cells. The optimal method may vary according to the size of the lesion. This should be taken into account when designing prospective trials using SFRT. © 2020 The Authors.
