BACKGROUND: There have been increasing concerns over health effects of low level exposure to cadmium, especially those on bones and kidneys. OBJECTIVE: To explore how age-adjusted geometric means of blood cadmium in adults varied by race/Hispanic origin, sex, and smoking status among U.S. adults and the extent to which the difference in blood cadmium by race/Hispanic origin and sex may be explained by intensity of smoking, a known major source of cadmium exposure...

Bioactive compounds, which are naturally produced in plants, have been concerned with the food and pharmaceutical industries because of the pharmacological effects on humans. In this study, the individual phenolics of six legumes during germination and antioxidant capacity from sprout extracts were determined. It was found that the phenolic content significantly increased during germination in all legumes. Peanuts showed the strongest antioxidant capacity in both the DPPH• (1,1-diphenyl-2-picrylhydrazyl) method and the reducing power assay (32...

Artificial lattices have been employed in a broad range of two-dimensional systems, including those with electrons, atoms and photons, in the quest for massless Dirac fermions with high flexibility and controllability. Establishing triangular or hexagonal symmetry, from periodically patterned molecule assembly or electrostatic gating as well as from moiré pattern induced by substrate, has produced electronic states with linear dispersions from two-dimensional electron gas (2DEG) residing in semiconductors, metals and graphene...

Two-dimensional van der Waals materials have shown novel fundamental properties and promise for wide applications. Here, we reported, for the first time, an experimental demonstration of the in-situ characterization and control of the anisotropic thermal conductivity of black phosphorus. We develop a novel platform based on lithium ion batteries that integrates ultrafast optical spectroscopy and electrochemical control to investigate the interactions between lithium ions and the lattices of the black phosphorus electrode...

I am honoured to present the 2016 British Journal of Sociology Annual Lecture at the London School of Economics. My lecture is based on ideas derived from my new book, The Scholar Denied: W.E.B. Du Bois and the Birth of Modern Sociology. In this essay I make three arguments. First, W.E.B. Du Bois and his Atlanta School of Sociology pioneered scientific sociology in the United States. Second, Du Bois pioneered a public sociology that creatively combined sociology and activism. Finally, Du Bois pioneered a politically engaged social science relevant for contemporary political struggles including the contemporary Black Lives Matter movement...

: The epidemiology of pediatric acute osteomyelitis in the USA, such as annual hospitalization rates and disparities with respect to age, sex, race/ethnicity, and socioeconomic status, remains unknown. We obtained discharge records of hospitalized patients with acute osteomyelitis younger than 20 years of age from the Kids Inpatient Database for 2006, 2009, and 2012. We weighted the records to estimate the number of hospitalizations in the USA and calculated the annual rates of hospitalization because of acute osteomyelitis...

The purpose of this study was to develop and validate a computer adaptive testing (CAT) version of the Addiction Severity Index-Multimedia Version (ASI-MV), the Addiction Severity CAT. This goal was accomplished in 4 steps. First, new candidate items for Addiction Severity CAT domains were evaluated after brainstorming sessions with experts in substance abuse treatment. Next, this new item bank was psychometrically evaluated on a large nonclinical (n = 4,419) and substance abuse treatment (n = 845) sample. Based on these results, final items were selected and calibrated for the creation of the Addiction Severity CAT algorithms...

Aviation is a substantial and a fast growing emissions source. Besides greenhouse gases, aircraft engines emit black carbon (BC), a climate forcer and air pollutant. Aviation BC emissions have been regulated and estimated through exhaust smoke visibility (smoke number). Their impacts are poorly understood because emission inventories lack representative data. Here, we measured BC mass and number-based emissions of the most popular airliner's engines according to a new emission standard. We used a calibrated engine performance model to determine the emissions on the ground, at cruise altitude, and over entire flight missions...

Phenotypic plasticity describes the ability of a given genotype to produce distinct phenotypes in different environments. We use the temperature sensitivity of abdominal pigmentation in Drosophila melanogaster females as a model to analyse the effect of the environment on development. We reported previously that thermal plasticity of abdominal pigmentation in females involves the pigmentation gene tan (t). However, the expression of the pigmentation gene yellow (y) was also modulated by temperature in the abdominal epidermis of pharate females...

In this work we perform a computational study comparing the influence of monovalent cation substitution by methylammonium (MA+), cesium (Cs+) and rubidium (Rb+) on the properties of formamidinium lead triiodide (FAPbI3)-based perovskites. The relative stability of the desired, photoactive perovskite α phase ("black phase") and the non-photoactive, non-perovskite δ phase ("yellow phase") is studied as a function of dopant nature, concentration and temperature. Cs+ and Rb+ are shown to be more efficient in the stabilization of the perovskite α phase than MA+...

Cetuximab is approved for treatment of squamous cell carcinoma of the head and neck (SCCHN). Cetuximab is generally well tolerated, but does carry a black box warning for infusion reactions (IRs). Incidence of IR in clinical trials was 15-20% for all grades and 3-5% for grades III-IV. Retrospective studies reported a higher incidence of all grade IRs and grades III-IV IR in areas of the Southeastern United States. Information regarding rechallenge doses after an IR has not been well described. At our institution, we frequently rechallenge on the same day after an initial IR...

Skin cancer is an important health problem worldwide among cancer types and results in death at a minimum level in the case of early diagnosis. Therefore, the application of prevention programs is vital. Nurses by definition take responsibility for programs in prevention, early diagnosis, and screening for cancer. This study was conducted to determine the extent of skin cancer knowledge and protective behaviors among nursing students in the West Black Sea Region of Turkey. This cross-sectional, descriptive study was conducted between February and May 2015...

The Rotating Snakes Illusion employs patterns with repetitive asymmetric luminance steps forming a "snake wheel." In the underlying luminance sequence {black, dark grey, white, light grey}, coded as {0, g1, 100, g2}, we varied g1 and g2 and measured illusion strength via nulling: Saccades were performed next to a "snake wheel" that rotated physically; observers adjusted rotation until a stationary percept obtained. Observers performed the perceptual nulling of the seeming rotation reliably. Typical settings for (g1, g2), measured from images by Kitaoka, are around (20%, 60%)...

A new species of frog of the genus Pristimantis is described from a montane forest between 1700 and 1800 m a.s.l. of the Pui Pui Protected Forest (Región Junín) in central Peru. Pristimantis ashaninkasp. n. is described based on five adult females (snout-vent length 23.1-26.7 mm) and ten juveniles (snout-vent length 10.6-13.4). It differs from its congeners by having the skin on dorsum shagreen with many conical tubercles giving it a spinose appearance, lacking a tympanum, having groin, anterior and posterior surfaces of thighs uniformly grayish brown, and a pale bronze iris with fine black reticulations, a median reddish hint horizontally across iris, and a black narrow vertical streak from pupil across lower and upper half of iris...

Grazoprevir is a potent pan-genotype, macrocyclic inhibitor of hepatitis C virus (HCV) NS3/4A protease and was developed for treating chronic HCV infection. In HCV genotype (GT) 1a, grazoprevir maintains potent activity against a majority of NS3 resistance-associated amino acid substitutions including the highly prevalent and naturally-occurring Q80K polymorphism that impacts simeprevir, another NS3/4A protease inhibitor. The basis for an unexpected difference in the clinical impact of some NS3 substitutions was investigated...

BACKGROUND: Post-stroke mortality is higher among residents of disadvantaged neighborhoods, but it is not known whether neighborhood inequalities are specific to stroke survival or similar to mortality patterns in the general population. We hypothesized that neighborhood disadvantage would predict higher poststroke mortality, and neighborhood effects would be relatively larger for stroke patients than for individuals with no history of stroke. METHODS AND RESULTS: Health and Retirement Study participants aged ≥50 years without stroke at baseline (n=15 560) were followed ≤12 years for incident stroke (1715 events over 159 286 person-years) and mortality (5325 deaths)...
