Abstract The associated risk of phthalate exposure, both parent compounds in the home and their metabolites urine, to childhood allergic respiratory morbidity, after adjusting for exposures indoor pollutants, especially bioaerosols, was comprehensively assessed. Levels five phthalates settled dust from homes 101 children (3–9 years old) were measured, along with corresponding urinary metabolites. Other environmental factors, including CO2, PM2.5, formaldehyde, 1,3-β-d-glucan, endotoxin,...

A single-phase bridgeless Cuk ac/dc power factor correction (PFC) rectifier with positive output voltage is proposed in this paper. For low product applications, the designed to convert high input voltage. Due no bridge diodes required and thus decreased conduction losses, efficiency can be improved. The operates discontinuous mode, current-loop circuit hence not needed. In addition, only a single switch used simplify control design. simple translation method have converter presented reduce...

Is there an association between exposure to phthalates and the timing of female puberty? Our study suggests that early onset puberty is related increased kisspeptin secretion. Girls are maturing earlier than in past decades quantity used consumer products has concurrently risen. The hypothesis may increase secretion thereby cause early-onset unexplored. This case–control ran from 2006 2009. We enrolled 104 girls. central precocious (CPP) (case) group were recruited a pediatric endocrinology...

Rechargeable nickel-ion batteries (RNiBs) have attracted significant attention because of their high volumetric density, low cost, environmental friendliness, and easy recyclability. In this study, a rechargeable nickel-iodine battery using rational design deep eutectic solvent (DES) electrolyte based on conversion reaction mechanism is first demonstrated. The Ni-I2 with the DES delivered specific capacity 201 mAh g-1 coulombic efficiency 82.5% over 65 cycles at current density 0.3 A g-1....

The Coronavirus Disease 2019 (COVID-19) pandemic continues to infect people worldwide. While the vaccinated population has been increasing, rising breakthrough infection persists in population. For living with virus, dietary guidelines prevent virus are worthy of and timely develop further. Tannic acid demonstrated be an effective inhibitor coronavirus is under clinical trial. Here we found that two other members tannins family, oligomeric proanthocyanidins (OPCs) punicalagin, also potent...

Diabetic retinopathy is characterized by vasopermeability, vascular leakage, inflammation, blood-retinal barrier breakdown, capillary degeneration, and neovascularization. However, the mechanisms underlying association between diabetes mellitus progression remain unclear.TPL2 (tumor locus 2), a serine-threonine protein kinase, exerts pathological effect on angiogenesis. This study investigated role of Nε-(carboxymethyl)lysine, major advanced glycation end products, involved TPL2-related...

This paper proposes a novel methodology for reducing the static linearity test time of SAR A/D converters. Due to low data conversion rate and high resolution, required measuring specifications such as INL DNL in converters can be 40% total converter time. The proposed method is based on fact that non-idealities code widths are correlated dominated by manufacturing variations specific components used design. Therefore, subset set directly affected these components, all estimated accurately....

Abstract Objectives To investigate the incidence of active tuberculosis (TB) among COPD patients using fluticasone/salmeterol or budesonide/formoterol, and to identify any differences between these two groups patients. Methods The study enrolled from Taiwan NHIRD who received treatment with budesonide/formoterol for > 90 days 2004 2011. TB was primary outcome. Results Among intention-to-treat population prior matching, rates were 0.94 0.61% in groups, respectively. After group had...

Conductive bridge random access memories (CBRAMs) are one of the promising nonvolatile for next generation technology. The resistive switching behavior CBRAMs relies on formation and rupture filaments in layer by cation injection from active metal electrode. However, suffered an overinjection cation, deteriorating performance. In this regard, we developed vertical alignment MoSe2 (v-MoSe2) a plasma-assisted chemical vapor reaction to prevent overmigration Cu species. With insertion v-MoSe2...

Abstract Liquid chromatography/mass spectrometry (LC/MS) and liquid chromatography/tandem mass (LC/MS/MS) were applied to characterize drug metabolites. Although these two methods have overcome the identification structural characterization of metabolites analysis, they remain time‐consuming processes. In this study, a novel multiple‐stage tandem spectrometric method (MS n ) was evaluated for new minor metabolism profiling penicillin G, one β‐lactam antibiotics, in human serum. Seven...
