BACKGROUND: Whether the consequences of diabetes mellitus (DM) are worse for women than for men treated with drug-eluting stents (DES) and antiplatelet therapy remain unclear. METHODS: Patients from the Assessment of Dual Antiplatelet Therapy With Drug-Eluting Stents study were stratified according to sex and DM status. We investigated the sex-specific effect of DM on high on-clopidogrel platelet reactivity (HPR), defined as a P2Y12 reaction units ≥208, and the adjusted association of DM on the 2-year risk for coronary thrombotic events (CTE), defined as spontaneous myocardial infarction or definite or probable stent thrombosis...

Research suggests that alcohol use and misuse are higher among lesbian, gay and bisexual than heterosexual populations, yet the social context of drinking in sexual minority communities has rarely been examined. To explore lesbian, gay, bisexual and transgender (LGBT) people's relationship with alcohol, we conducted seven focus groups (N = 33) with pre-existing groups of friends and work colleagues (18 to 52 years) in Scotland, UK. We identified and analysed patterns in our data using thematic analysis. Respondents perceived heavy drinking as central to the commercial gay scene...

The interplay between mechanical strains and battery electrochemistry, or the tunable mechanochemistry of batteries, remains an emerging research area with limited experimental progress. In this report, we demonstrate how elastic strains applied to vanadium pentoxide (V2O5), a widely studied cathode material for Li-ion batteries, can modulate the kinetics and energetics of lithium-ion intercalation. We utilize atomic layer deposition to coat V2O5 materials onto the surface of a shapememory superelastic NiTi alloy, which allows electrochemical assessment at a fixed and measurable level of elastic strain imposed on the V2O5, with strain state assessed through Raman spectroscopy and X-ray diffraction...

BACKGROUND: Breast cancer is a heterogeneous and polygenic disease that can be divided into different molecular subtypes based on histological and genomic features. To date, numerous susceptibility loci of breast cancer have been discovered by genome-wide association studies and may expand the genetic features. However, few loci have been further studied according to molecular subtypes. MATERIALS AND METHODS: We genotyped 23 recently discovered single nucleotide polymorphisms using the Sequenom iPLEX platform in a female Chinese cohort of 3,036 breast cancer patients (2,935 samples matched molecular subtypes) and 3,036 healthy controls...

The culm development of rice is characterized by elongation and medullary cavity (MC) formation, which are determined by node formation meristem and residual meristem, respectively. Although many factors have been shown to affect culm elongation, molecules involved in MC formation remained to be identified. In this study, we show that a point mutation in SHORT and SOLID CULM (SSC), the rice homologue of Arabidopsis LFY, resulted in plants with drastically reduced culm length and completely abolished MC formation...

The liver is the largest internal organ and filters around 3 pints of blood per minute. This continuous flux of blood should not be confused with rapid egress of lymphocytes through the liver; this organ has intricate corridors of specialized sinusoidal spaces, ensuring that immune cells decelerate to shear flow rates, and providing ample opportunities to interact with parenchymal cells. Migration has been intricately linked to T cell function; it is therefore important to study liver T cell biology into context within the liver microenvironment...

This study applies atom probe tomography (APT) to analyze the oxide scales formed on model NiAlCr alloys doped with Hf, Y, Ti, and B. Due to its ability to measure small amounts of alloying elements in the oxide matrix and its ability to quantify segregation, the technique offers a possibility for detailed studies of the dopant's fate during high-temperature oxidation. Three model NiAlCr alloys with different additions of Hf, Y, Ti, and B were prepared and oxidized in O2 at 1,100°C for 100 h. All specimens showed an outer region consisting of different spinel oxides with relatively small grains and the protective Al2O3-oxide layer below...

The genetic substitution of transformation amenability alleles from 'Golden Promise' can facilitate the development of transformation-efficient lines from recalcitrant barley cultivars. Barley (Hordeum vulgare) cv. 'Golden Promise' is one of the most useful and well-studied cultivars for genetic manipulation. In a previous report, we identified several transformation amenability (TFA) loci responsible for Agrobacterium-mediated transformation using the F2 generation of immature embryos, derived from 'Haruna Nijo' × 'Golden Promise,' as explants...

Geomagnetic dipole moment variations associated with polarity reversals and excursions are expressed by large changes of the cosmogenic nuclide beryllium-10 ((10)Be) production rates. Authigenic (10)Be/(9)Be ratios (proxy of atmospheric (10)Be production) from oceanic cores therefore complete the classical information derived from relative paleointensity (RPI) records. This study presents new authigenic (10)Be/(9)Be ratio results obtained from cores MD05-2920 and MD05-2930 collected in the west equatorial Pacific Ocean...

BACKGROUND: In multicenter studies, tight glycemic control targeting a normal blood glucose level has not been shown to improve outcomes in critically ill adults or children after cardiac surgery. Studies involving critically ill children who have not undergone cardiac surgery are lacking. METHODS: In a 35-center trial, we randomly assigned critically ill children with confirmed hyperglycemia (excluding patients who had undergone cardiac surgery) to one of two ranges of glycemic control: 80 to 110 mg per deciliter (4...

Sodium-ion batteries (SIBs) have been pursued as a more cost-effective and more sustainable alternative to lithium-ion batteries (LIBs), but these advantages come at the expense of energy density. In this work, we demonstrate that the challenge of energy density for sodium chemistries can be overcome through an anode-free architecture enabled by the use of a nanocarbon nucleation layer formed on Al current collectors. Electrochemical studies show this configuration to provide highly stable and efficient plating and stripping of sodium metal over a range of currents up to 4 mA/cm(2), sodium loading up to 12 mAh/cm(2), and with long-term durability exceeding 1000 cycles at a current of 0...

Prenatal cadmium (Cd) exposure has been associated with adverse birth outcomes, but the findings of previous studies are inconsistent. We measured Cd concentrations in urine samples at or near 13, 24, and 35 gestational weeks from 282 women in Wuhan, China. We used generalized estimating equation models to assess the associations between maternal creatinine adjusted urinary Cd concentrations at each trimester and birth size. A significant inverse association was observed between higher maternal Cd levels measured during the 1st trimester and birth size in girls...
