To prevent Ebola transmission, frequent handwashing is recommended in Ebola Treatment Units and communities. However, little is known about which handwashing protocol is most efficacious. We evaluated six handwashing protocols (soap and water, alcohol-based hand sanitizer (ABHS), and 0.05% sodium dichloroisocyanurate, high-test hypochlorite, and stabilized and non-stabilized sodium hypochlorite solutions) for 1) efficacy of handwashing on the removal and inactivation of non-pathogenic model organisms and, 2) persistence of organisms in rinse water...

Feed and food production are inter alia reasons for high greenhouse gas emissions. Greenhouse gas emissions could be reduced by the replacement of animal components with plant components in processed food products, such as pasta. The main components currently used for pasta are semolina, and water, as well as additional egg. The hypothesis of this paper is that the substitution of whole egg with plant-based ingredients, for example from peas, in such a product might lead to reduced greenhouse gas emissions (GHG) and thus a reduced carbon footprint at economically reasonable costs...

The synthesis of substituted γ- and δ-lactams via palladium-catalyzed alkene carboamination reactions between aryl halides and alkenes bearing pendant amides is described. The substrates for these reactions are generated in 1-3 steps from commercially available materials, and products are obtained in good yield with up to >20:1 diastereoselectivity. The stereochemical outcome of the alkene addition is consistent with a mechanism involving anti-aminopalladation of the alkene.

BACKGROUND AND OBJECTIVES: The diagnosis of pulmonary nodules of unknown origin is challenging, and such nodules are not always suitable for transthoracic needle biopsy. With the advent of video assisted thoracic surgery (VATS) and CT-guided percutaneous hookwire localization (CT-PHL) we hypothesized that the combination of these two procedures will improve early diagnosis. METHODS: Selection criteria were a nodule not well approachable with fine needle biopsy and the therapeutic consequences of a diagnosis as assessed by the multidisciplinary oncology board...

Intra-guild predation (IGP) is an important phenomenon structuring ecological communities and affects the success of biological control. Here we show that parasitism by the koinobiont wasp Cotesia vestalis is associated with behavioural changes in its larval host (diamondback moth, Plutella xylostella) that reduce risk of IGP. Compared with unparasitised caterpillars, parasitised P. xylostella moved less frequently to new feeding patches on plants and were less likely to fall from the plant. Wolf spiders killed significantly fewer parasitised larvae...

Altered expression of nephrin underlies the pathophysiology of proteinuria in both congenital and acquired nephrotic syndrome. However, the epigenetic mechanisms of nephrin gene regulation remain elusive. Here, we show that Wolf-Hirschhorn syndrome candidate 1-like 1 long form (WHSC1L1-L) is a novel epigenetic modifier of nephrin gene regulation. WHSC1L1-L was associated with histone H3K4 and H3K36 in human embryonic kidney cells. WHSC1L1-L gene was expressed in the podocytes and functional protein product was detected in these cells...

This study evaluated the techno-economic performance and potential benefits of methanol production through catalytic gasification of forest residues and lignin. The results showed that while catalytic gasification enables increased cold gas efficiencies and methanol yields compared to non-catalytic gasification, the additional pre-treatment energy and loss of electricity production result in small or no system efficiency improvements. The resulting required methanol selling prices (90-130€/MWh) are comparable with production costs for other biofuels...

Long-lived plasma cells (PCs) in the bone marrow (BM) are a critical source of antibodies after infection or vaccination, but questions remain about the factors that control PCs. We found that systemic infection alters the BM, greatly reducing PCs and regulatory T (Treg) cells, a population that contributes to immune privilege in the BM. The use of intravital imaging revealed that BM Treg cells display a distinct behavior characterized by sustained co-localization with PCs and CD11c-YFP(+) cells. Gene expression profiling indicated that BM Treg cells express high levels of Treg effector molecules, and CTLA-4 deletion in these cells resulted in elevated PCs...

Retinal prosthetic devices can significantly and positively impact the ability of visually challenged individuals to live a more independent life. We describe a visual processing system which leverages image analysis techniques to produce visual patterns and allows the user to more effectively perceive their environment. These patterns are used to stimulate a retinal prosthesis to allow self guidance and a higher degree of autonomy for the affected individual. Specifically, we describe an image processing pipeline that allows for object and face localization in cluttered environments as well as various contrast enhancement strategies in the "implanted image...

Primary biliary cholangitis (formerly known as primary biliary cirrhosis) has been a classic indication for liver transplantation for more than thirty years (1). Due to the changing epidemiology of liver diseases combined with the universal lack of post-mortal grafts, the question of prioritizing allocation amongst sick patients competing for these rare grafts on the waiting list remains an unresolved challenge. In their UNOS database analysis Ashwani Singal and coworkers focus on wait-list mortality for a nowadays rare indication for liver transplantation: primary biliary cholangitis (PBC) (2)...

INTRODUCTION: Early ambulation is the principal objective in trans-femoral amputees. Postamputation modifications complicate the rehabilitation process due to a reduced control at the interface between stump and prosthesis. The aim of this study is to determine whether magnetic resonance imaging depicts the amount of fatty degeneration of the thigh muscles after trans-femoral amputation (TFA). METHODS: A total of 12 patients following a TFA on the basis of a bone neoplasm or metastasis with an evaluable postoperative MRI were identified...

Infection with Listeria monocytogenes during pregnancy is associated with miscarriage, preterm birth, and neonatal complications, including sepsis and meningitis. While the risk of these conditions is thought to be greatest during the third trimester of pregnancy, the determinants of fetoplacental susceptibility to infection, the contribution of gestational age, and the in vivo progression of disease at the maternal-fetal interface are poorly understood. We developed a nonhuman primate model of listeriosis to better understand antecedents of adverse pregnancy outcomes in early pregnancy...

The Interleukin (IL)-1β induced activation of the p38(MAPK)/MK2 pathway in hepatocytes is important for the control of acute phase response and regulation of liver regeneration. Many aspects of regulatory relevance of this pathway have been investigated in immune cells in the context of inflammation. However, very little is known about concentration-dependent activation kinetics and signal propagation in hepatocytes and the role of MK2. We established a mathematical model for IL-1β induced activation of the p38(MAPK)/MK2 pathway in hepatocytes that was calibrated to quantitative data on time- and IL-1β concentration-dependent phosphorylation of p38(MAPK) and MK2 in primary mouse hepatocytes...

Chronic low-grade inflammation and cellular stress are important contributors to obesity-linked metabolic dysfunction. Here, we uncover an immune-metabolic role for C1q/TNF-related protein 7 (CTRP7), a secretory protein of the C1q family with previously unknown function. In obese humans, circulating CTRP7 levels were markedly elevated and positively correlated with BMI, glucose, insulin, insulin resistance index, hemoglobin A1c, and triglyceride levels. Expression of CTRP7 in liver was also significantly upregulated in obese humans and positively correlated with gluconeogenic genes...

BACKGROUND: Radioresistance is a common feature of head and neck squamous cell carcinoma (HNSCC). We previously showed that the irradiation- activated vascular endothelial growth factor (VEGF)-extracellular signal-regulated kinase (ERK)-axis is fundamental for the survival of resistant tumors. In this study, we examined if treatment with potent multikinase (MK) inhibitors, sorafenib and sunitinib, could radiosensitize tumor cells. METHODS: Cultured HNSCC cell lines were treated with inhibitors and subsequently irradiated...

BACKGROUND: Good results have been reported for angioplasty and stenting of post-thrombotic lesions of the iliac and proximal femoral veins. If lesions at the origin of the superficial femoral and profunda veins are stented, the intraluminal synechiae can be pushed against the orifices of inflow vessels, potentially decreasing stent inflow. Surgical disobliteration of the common femoral vein (endophlebectomy) has been suggested to mitigate this problem. Because of a temporary increase in thrombogenicity, this procedure may be accompanied by arteriovenous fistula creation...

In this edition of this column, we review new studies concerning the pathophysiology, treatment, and outcomes of patients with necrotizing myopathy, genetic testing in congenital myopathies, and limb girdle muscular dystrophies, and the incidence of polyneuropathy in the myotonic dystrophies. Various studies in myasthenia gravis, including those concerning antibody testing, clinical features, and quality of life are also reviewed as are recent findings in congenital myasthenic syndromes. Finally, 2 studies concerning polyneuropathy are discussed, including one on the association of polyneuropathy in patients with the metabolic syndrome and one on laboratory testing in patients with otherwise idiopathic small fiber polyneuropathy...

'Autosomal dominant tubulointerstitial kidney disease - UMOD' (ADTKD-UMOD) is caused by impaired maturation and secretion of mutant uromodulin (UMOD) in thick ascending limb of Henle loop (TAL) cells, resulting in endoplasmic reticulum (ER) stress and unfolded protein response (UPR). To gain insight into pathophysiology, we analysed proteome profiles of TAL-enriched outer renal medulla samples from ADTKD-UMOD and control mice by quantitative LC-MS/MS. In total, 212 differentially abundant proteins were identified...
