Contamination of raw milk with bacterial pathogens is potentially hazardous to human health. The aim of this study was to evaluate the total bacteria count (TBC) and presence of pathogens in raw milk in Northern China along with the associated herd management practices. A total of 160 raw milk samples were collected from 80 dairy herds in Northern China. All raw milk samples were analyzed for TBC and pathogens by culturing. The results showed that the number of raw milk samples with TBC <2 × 10(6) cfu/mL and <1 × 10(5) cfu/mL was 146 (91...

The advancement of nanoscale electronics has been limited by energy dissipation challenges for over a decade. Such limitations could be particularly severe for two-dimensional (2D) semiconductors integrated with flexible substrates or multi-layered processors, both being critical thermal bottlenecks. To shed light into fundamental aspects of this problem, here we report the first direct measurement of spatially resolved temperature in functioning 2D monolayer MoS2 transistors. Using Raman thermometry we simultaneously obtain tempera-ture maps of the device channel and its substrate...

Recycling endosomes are generally thought to play a central role in endocytic recycling, but recent evidence has indicated that they also participate in other cellular events, including cytokinesis, autophagy, and neurite outgrowth. Rab small GTPases are key regulators in membrane trafficking, and although several Rab isoforms, e.g., Rab11, have been shown to regulate recycling endosomal trafficking, the precise mechanism by which these Rabs regulate recycling endosomes is not fully understood. In this study, we focused on a Rab-GTPase-activating protein (Rab-GAP), one of the key regulators of Rabs, and comprehensively screened 43 mammalian Tre-2/Bub2/Cdc16 (TBC)/Rab-GAP-domain-containing proteins (TBC proteins) for proteins that specifically localize on recycling endosomes in mouse embryonic fibroblasts (MEFs)...

Mutations in the TBC1D24 gene (MIM 613577) cause familial infantile myoclonic epilepsy (FIME; 605021) and early infantile epileptic encephalopathy-16 (EIEE16; 615338), both inherited with an autosomal recessive trait. The TBC1D24 gene encodes a member of the TBC family domain proteins, involved in cell signaling and oxidative stress resistance. We studied, by a Next Generation Sequencing (NGS) target re-sequencing gene approach, the DNA of a 5 year-old girl, affected by recurrent attacks of Alternating Hemiplegia (AH) and by recurrent episodes of Epilepsia Partialis Continua (EPC)...

Tubulobulbar complexes are clathrin/actin-based structures that internalize intercellular junctions in the testis. They resemble coated pits with extremely long necks that are cuffed by dendritic actin networks. As the structures mature, a swollen region or bulb develops near the end of each complex. The bulbs lack actin cuffs and are closely associated with cisternae of endoplasmic reticulum. The bulbs expand and are internalized and enter endocytic compartments of the Sertoli cell. Previous immunofluorescence studies have demonstrated that markers for early endosomes (Rab5 and EEA1) are associated with tubulobulbar complexes and are localized at or near the ends of the structures...

TBC1D15 belongs to the TBC (Tre-2/Bub2/Cdc16) domain family and functions as a GTPase-activating protein (GAP) for Rab GTPases. So far, the structure of TBC1D15 or the TBC1D15·Rab complex has not been determined, thus, its catalytic mechanism on Rab GTPases is still unclear. In this study, we solved the crystal structures of the Shark and Sus TBC1D15 GAP domains, to 2.8 Å and 2.5 Å resolution, respectively. Shark-TBC1D15 and Sus-TBC1D15 belong to the same subfamily of TBC domain-containing proteins, and their GAP-domain structures are highly similar...

Analysis of carbohydrates from complex biological samples often requires their isolation from proteins and other contaminants to avoid interference. An effective separation of mannan-protein mixtures by 1-butyl-3-methylimidazolium bromide/K2HPO4 ionic liquid aqueous two-phase system (IL-APTS) is reported. Extraction efficiency of bovine serum albumin (BSA) ranged from 92% to 97% while extraction efficiency of mannan reached values from 95% to about 100% depending on phase and/or model sample composition. On the contrary, lower efficiency of BSA removal (73-84%) was recorded for lectin affinity purification with concanavalin A-triazine bead cellulose (Con A-TBC); the low mannan-binding capacity was limiting factor here...

BACKGROUND: Blood pressure (BP) is poorly controlled among a large proportion of hypertensive outpatients. Innovative models of care are therefore needed to improve BP control. The Team-Based Care for improving Hypertension management (TBC-HTA) study aims to evaluate the effect of a team-based care (TBC) interprofessional intervention, involving nurses, community pharmacists and physicians, on BP control of hypertensive outpatients compared to usual care in routine clinical practice. METHODS/DESIGN: The TBC-HTA study is a pragmatic randomized controlled study with a 6-month follow-up which tests a TBC interprofessionnal intervention conducted among uncontrolled treated hypertensive outpatients in two ambulatory clinics and among seven nearby community pharmacies in Lausanne and Geneva, Switzerland...

Chinese Hamster Ovary (CHO) cells are the most commonly used host for the production of biopharmaceuticals. Although transcription and translation engineering strategies have been employed to generate high-producer cell clones, the secretory pathway still remains a bottleneck in cellular productivity. In this study we show that ectopic expression of a human mitochondrial genome-encoded small RNA (mitosRNA-1978) in an IgG expressing CHO cell line strongly improved specific productivity by functioning in a microRNA-like fashion...

According to recent estimates, 2%-15% of couples are sterile, and approximately half of the infertility cases are attributed to male reproductive factors. However, the reasons remain undefined in approximately 25% of male infertility cases, and most infertility cases exhibit spermatogenic defects. Numerous genes involved in spermatogenesis still remain unknown. We previously identified Male Germ Cells Rab GTPase-Activating Proteins (MGCRABGAPs) through cDNA microarray analysis of human testicular tissues with spermatogenic defects...

The influence of tides on bacterial populations in a monsoon influenced tropical estuary was assessed through fine resolution sampling (1 to 3 h) during spring and neap tides from mouth to the freshwater end at four stations during pre-monsoon, monsoon and post-monsoon seasons. Higher abundance of total bacterial count (TBC) in surface water near the river mouth, compared to the upstream, during pre-monsoon was followed by an opposite scenario during the monsoon When seasonally compared, it was during the post-monsoon season when TBC in surface water was highest, with simultaneous decrease in their count in the river sediment...

The average residual stress distribution as a function of depth in an air plasma-sprayed yttria stabilized zirconia top coat used in thermal barrier coating (TBC) systems was measured using synchrotron radiation X-ray diffraction in reflection geometry on station I15 at Diamond Light Source, UK, employing a series of incidence angles. The stress values were calculated from data deconvoluted from diffraction patterns collected at increasing depths. The stress was found to be compressive through the thickness of the TBC and a fluctuation in the trend of the stress profile was indicated in some samples...

We investigate the role of interfacial electronic properties on the phonon transport in two-dimensional MoS2 adsorbed on metal substrates (Au and Sc) using first-principles density functional theory and the atomistic Green's function method. Our study reveals that the different degree of orbital hybridization and electronic charge distribution between MoS2 and metal substrates play a significant role in determining the overall phonon-phonon coupling and phonon transmission. The charge transfer caused by the adsorption of MoS2 on Sc substrate can significantly weaken the Mo-S bond strength and change the phonon properties of MoS2, which result in a significant change in thermal boundary conductance (TBC) from one lattice-stacking configuration to another for same metallic substrate...

OBJECTIVE/BACKGROUND: Tuberculosis (TB) is a worldwide public health problem. It is a contagious and grave disease caused by Mycobacterium tuberculosis. Current drugs such as isoniazid, pyrazinamide, and rifampicin used for the treatment of tuberculosis are potentially hepatotoxic and can lead to drug hepatitis. In order to improve the follow-up of TB patients in Cameroon, we carried out a study which aimed to evaluate the hepatotoxicity risk factors associated with anti-TB drugs. METHODS: The studies were performed on 75 participants who had visited the Loum District Hospital located in the littoral region of Cameroon for their routine consultation...
