Trichodysplasia spinulosa (TS) is a rare dermatologic complication associated with the immunosuppressive therapy used in solid organ transplantation. The distinctive clinical manifestation of this condition is spiny follicular papules on the face, ears, extremities, and trunk. Histopathologically, abnormally maturing hair follicles with hyperkeratotic material are noted. The condition is produced by the trichodysplasia spinulosa-associated polyomavirus. Treatment of this condition in the past has entailed a reduction in immunosuppression, topical agents such as cidofovir or retinoidsm or oral valganciclovir...

Context, Objectives: Turner syndrome (TS) is due to a complete or partial loss of an X chromosome in females and is not currently part of newborn screening. Diagnosis is often delayed resulting in missed crucial diagnostic and therapeutic opportunities. This study sought to determine if whole-exome sequencing (WES) as part of a potential newborn screening program could be used to diagnose TS. Design, Setting, Patients: Karyotype, chromosomal microarray, and WES were performed on women with TS (n=27) enrolled in the Personalized Genomic Research study at the National Institutes of Health...

The National Institute of Mental Health (NIMH) has made sustained investments in the development of genomic resources over the last two decades. These investments have led to the development of the largest biorepository for psychiatric genetics as a centralized national resource. In the realm of genomic resources, NIMH has been supporting large team science (TS) consortia focused on gene discovery, fine mapping of loci, and functional genomics using state-of-the-art technologies. The scientific output from these efforts has not only begun to transform our understanding of the genetic architecture of neuropsychiatric disorders, but it has also led to a broader cultural change among the investigator community towards deeper collaborations and broad pre-publication sharing of data and resources...

INTRODUCTION: Controversy exists on optimal operative treatment of vertically unstable Neer IIB lateral clavicle fractures. Aim of this study was to analyse and compare clinical and radiological results and complications of locking plate osteosynthesis (LPO) versus hook plate osteosynthesis (HPO) with acromioclavicular joint (ACJ) stabilization. The hypothesis was, that HPO would recreate coracoclavicular stability more effectively and potentially lead to a superior outcome. METHODS: This retrospective, observational cohort study included 32 patients (19 HPO, 13 LPO) with a mean age of 44...

REVIEW
Xinyou Ma, William L Hase
Non-statistical chemical dynamics are exemplified by disagreements with the transition state (TS), RRKM and phase space theories of chemical kinetics and dynamics. The intrinsic reaction coordinate (IRC) is often used for the former two theories, and non-statistical dynamics arising from non-IRC dynamics are often important. In this perspective, non-statistical dynamics are discussed for chemical reactions, with results primarily obtained from chemical dynamics simulations and to a lesser extent from experiment...

Patricio Neumann, Zenón González, Gladys Vidal
The influence of sequential ultrasound and low-temperature (55°C) thermal pretreatment on sewage sludge solubilization, enzyme activity and anaerobic digestion was assessed. The pretreatment led to significant increases of 427-1030% and 230-674% in the soluble concentrations of carbohydrates and proteins, respectively, and 1.6-4.3 times higher enzymatic activities in the soluble phase of the sludge. Optimal conditions for chemical oxygen demand solubilization were determined at 59.3kg/L total solids (TS) concentration, 30,500kJ/kg TS specific energy and 13h thermal treatment time using response surface methodology...

In this study, different ultrasound power intensities of 0.05-0.21kW/L (4.13-16.52kWh/kg TS) were applied at a frequency of 20kHz and for durations of 5-20min to digestate obtained from a domestic wastewater treatment plant. The ultrasonic effect on digestate solubilization was revealed by increased levels of soluble Chemical Oxygen Demand (sCOD), soluble Total Organic Carbon (sTOC), and soluble Total Nitrogen (sTN) released into the solution. The highest material release was achieved at an ultrasonic energy intensity of 0...

Shiga toxin-producing Escherichia coli (STEC) are responsible for human infections, ranging from mild watery diarrhea to hemorrhagic colitis (CH) that may be complicated by hemolytic uremic syndrome (HUS). The main STEC virulence factor is Shiga toxin encoded by the stx gene, located in the genome of a bacteriophage integrated into the bacterial chromosome. The serotype O26:H11 is the second HUS-causing serotype worldwide (after O157:H7), and the first found in dairy products such as raw-milk cheeses. A small number of HUS cases identified each year in France are caused by serotype O26:H11...

A dynamic membrane (DM) module was inserted into a fermentation reactor to separate soluble products from the fermented mixture to increase lactic acid (LA) production from food wastes under acidogenic conditions (uncontrolled pH, pH 4 and 5). With a high total suspended solid content (20-40g/L) in the fermenter, a stable DM could be maintained through regular backwashing. By effectively intercepting suspended solids and lactic acid bacteria (LAB), the fermenter was able to increase microbial activity and largely promote LA yield...

Semliki Forest virus (SFV) is a potential cancer gene therapy vector capable of providing high and transient expression of heterologous proteins in mammalian cells. However, SFV has shown suboptimal transduction levels in several cancer cell types as well as wide biodistribution of SFV has been observed after in vivo applications. Magnetic nanoparticles (MNPs) have been shown to increase cell transduction with several viral vectors in vitro under an external magnetic field and enhance magnetically guided viral vector delivery...

BACKGROUND: The optimal interventional technique for addressing coronary bifurcation lesions is debatable. Long-term clinical outcomes with provisional stenting (PS) compared with a two-stent (TS) strategy for bifurcation lesions are scarce. We aim to perform the first meta-analysis of randomised controlled trials (RCTs) to explore long-term outcomes comparing both strategies. METHODS: An electronic search was performed for online databases until August 2016 for RCTs comparing PS with TS for bifurcation lesions reporting outcomes at 1 year of follow-up or more...

BACKGROUND: Fifteen chalcones were subjected to quantitative structure-activity relationship (QSAR) analysis based on their cytotoxicity and tumor specificity, in order to find their new biological activities. MATERIALS AND METHODS: Cytotoxicity against four human oral squamous cell carcinoma cell lines and three oral mesenchymal cells was determined by the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) method. Tumor specificity (TS) was evaluated by the ratio of the mean 50% cytotoxic concentration (CC50) against normal cells to that against tumor cell lines...

Lu Wang, Tao Zhang, Wei Sun, Zeyu He, Chungu Xia, Yu Lan, Chao Liu
A deoxygenative gem-diborylation and gem-silylborylation of aldehydes and ketones is described. The key for the success of this transformation is the base-promoted C-O bond borylation or silylation of the generated α-oxyboronates. Experimental and theoretical studies exhibit that the C-O bond functionalization proceeds via an intramolecular five-membered transition-state (9-ts) boryl migration followed by a 1,2-metallate rearrangement with OBpin as a leaving group. The transformation occurs with an inversion on the carbon center...

The newest weapon in cancer therapy is checkpoint inhibition, which is the result of basic immunology research. The success of this therapy is based on the fact that upon light microscopy, many solid tumors harbor lymphocytic cells infiltrating the tumor (TILs), and in many solid tumors, the presence of these TILs are prognostic. Ipilimumab was the first monoclonal antibody developed against a target present on T cells after becoming activated, CTLA-4. In malignant melanoma, ipilimumab showed its beneficial effect as compared to a placebo peptide...

Batch solid-phase anaerobic digestion is a technology for sustainable on-farm treatment of solid residues, but is an emerging technology that is yet to be optimised with respect to start-up and inoculation. In the present study, spent bedding from two piggeries (site A and B) were batch digested at total solids (TS) concentration of 5, 10 and 20% at mesophilic (37°C) and thermophilic (55°C) temperatures, without adding an external inoculum. The results showed that the indigenous microbial community present in spent bedding was able to recover the full methane potential of the bedding (140±5 and 227±6L CH4 kgVSfed(-1) for site A and B, respectively), but longer treatment times were required than for digestion with an added external inoculum...

The World Health Organization Study Group on Tobacco Product Regulation (WHO TobReg) proposed mandated ceilings on 9 prioritized mainstream cigarette smoke constituents determined from the market-specific median of nicotine-normalized yield distributions. Considering the requirements for assessing and reporting of compliance with ceilings, it is of great importance to estimate the measurement uncertainty. To have a better understanding of influence of measurement uncertainty on the WHO recommended regulation for cigarette smoke constituents, in the present study, the measurement uncertainties were evaluated systematically based on series of collaborative studies reported by three different authorities over the years from 2012 to 2016, according to the approaches guided in ISO/TS 21748...

Loop-mediated isothermal amplification (LAMP) has been used to detect several pathogens including malaria parasites from field and clinical samples. In this protocol, the malaria LAMP technology is developed to differentiate between Plasmodium falciparum (Pf) and Plasmodium vivax (Pv) species by targeting the dihydrofolate reductase thymidylate synthase (dhfr-ts) gene, a known target for the antifolate class of drugs such as Pyrimethamine. LAMP primer sets are designed and validated for species specific amplification...
