Zinc (Zn) deficiency in human populations depending on cereals as a main source of Zn is a global malnutrition problem. In this field study, we investigated the potential of green manure application to increase soil Zn availability and wheat grain Zn concentrations (biofortification) on a Luvisol with different long-term fertilizer management. We also studied cadmium (Cd), as wheat is a major contributor of this undesired non-essential element to human diets. Clover (Trifolium alexandrinum L.), mustard (Sinapis alba L...

Increasing concentrations of anthropogenic antibiotics in soils are partly responsible for the proliferation of bacterial antibiotic resistance. However, little is known about how soil-sorbed antibiotics exert selective pressure on bacteria in unsaturated soils. This study investigated the bioavailability of tetracycline sorbed on three soils (Webster clay loam, Capac sandy clay loam, and Oshtemo loamy sand) to a fluorescent Escherichia coli bioreporter under unsaturated conditions using agar diffusion assay, microscopic visualization, and model simulation...

Development of personalized skin treatment in medicine and skin care may benefit from simple and accurate evaluation of the fraction of senescent skin fibroblasts that lost their proliferative capacity. We examined whether enriched analysis of colonies formed by primary human skin fibroblasts, a simple and widely available cellular assay, could reveal correlations with the fraction of senescent cells in heterogenic cell population. We measured fractions of senescence associated β-galactosidase (SA-βgal) positive cells in either mass cultures or colonies of various morphological types (dense, mixed and diffuse) formed by skin fibroblasts from 10 human donors...

OBJECTIVES: The diffusing capacity of the lung for carbon monoxide (DL CO ) is an indicator of lung damage. We sought to determine whether DL CO is associated with the aggressiveness of lung adenocarcinoma using histopathological indexes, such as tumour differentiation, scar grade, nuclear atypia and the mitotic index. METHODS: Fifty-seven patients with low DL CO (≤80% of predicted) and 466 patients with normal DL CO (>80% of predicted) who underwent R0 resection of lung adenocarcinoma between 2005 and 2012 were retrospectively reviewed...

BACKGROUND: We have found clusters of Klebsiella pneumoniae with OXA48-carbepenemase cases in some hospital rooms, and decided to investigate whether bathroom siphons could be a reservoir for OXA48 bacteria, as occurs with K. oxytoca with other types of carbepenemases. METHODS: We evaluated the microbial competition between strains with OXA48 and VIM carbepenemases, in diluted nutrient-broth, on a slime germ-carrier. We compared the number of colonies at 5 and 10 days on the contaminated carriers with one or two strains...

PURPOSE: There has been suggestion that a greater "pulmonary vascular reserve" defined by a low pulmonary vascular resistance (PVR) and a high lung diffusing capacity (DL) allows for a superior aerobic exercise capacity. How pulmonary vascular reserve might affect exercise capacity at moderate altitude is not known. METHODS: Thirty-eight healthy subjects underwent an exercise stress echocardiography of the pulmonary circulation, combined with measurements of DL for nitric oxide (NO) and carbon monoxide (CO) and a cardio-pulmonary exercise test at sea level and at the altitude of 2250m...

In this work, oxygen-deficient anatase TiO2 nanosheets (A-TiO2-xNSs) are proposed as the substrate to improve the electrochemical properties of sulfur electrodes for lithium-sulfur battery (Li-S batteries). The A-TiO2-xNSs are prepared via partly reducing the pristine TiO2 nanosheets (A-TiO2NSs) in the NaBH4 solution. With some oxygen vacancies on the surface of TiO2 nanosheets, A-TiO2-xNSs can not only promote the electronic transfer but also act as more effective polysulfide reservoirs to minimize the dissolution of lithium polysulfides (LiPSs) than the A-TiO2NSs control...

BACKGROUND: The protein deacetylase sirtuin-1 (SIRT1) is an anti-aging molecule that is decreased in the lung from patients with chronic obstructive pulmonary disease (COPD). Recently, SIRT1 was reported to be detectable in serum, but serum SIRT1 levels have not yet been reported in patients with COPD. METHODS: Serum SIRT1 was measured by Western blotting, and relative ratio of band density in samples against that of a positive control were calculated. RESULTS: Several molecular sizes of SIRT1, including 120kDa (actual size) and fragments (102, 75kDa) were quantified by Western blotting...

An ultrasensitive surface plasmon resonance (SPR) immunoassay was developed for the specific detection of human cardiac troponin I (cTnI), a principle diagnostic marker for myocardial damage. The thin gold film evaporated on a glass slate, which was employed as the SPR sensing film, was modified by hollow gold nanoparticles (HGNPs) and polydopamine (PDA) sequentially, and then was immobilized with antibodies for specific recognition of target analyte. Electronic coupling of the surface plasmon waves originating from the HGNPs and the gold film leads to the remarkable amplification of SPR response...

Searching the long-life transition metal oxide (TMOs)-based materials for future lithium ion batteries (LIBs) is still a great challenge because of the mechanical strain resulted from volume change of TMO anodes during the lithiation/delithiation process. To well address this challenging issue, we demonstrate a controlled method for making the multi-shelled TMOs hollow microfibers with tunable shell numbers to achieve the optimal void for efficient lithium ion storage. Such particularly designed void can lead to a short diffusion distance for fast diffusion of Li+ ions and also withstand large volume variation upon cycling, both of which are the key for high-performance LIBs...

BACKGROUND: Rheumatoid arthritis-associated interstitial lung disease (RA-ILD) is associated with significant morbidity and mortality. Similarities have been observed between patients with idiopathic pulmonary fibrosis (IPF) and the UIP (usual interstitial pneumonia) form of RA-ILD. The GAP (gender, age, physiology) model has been shown to predict mortality in patients with IPF, but its ability to predict mortality in RA-ILD is not known. METHODS: We identified 309 patients with RA-ILD at 4 academic centers with ongoing longitudinal cohorts of patients with ILD...

The wintertime haze day (HD) in the Yangtze River Delta (YRD) region of China shows a significant upward trend during the past decades due to the rapid industrialization and urbanization. Besides the enhanced anthropogenic emission, climate change also plays the important role in the long term HD variations. In this study, the significant decadal variation of wintertime HD during the period 1960-2012 in YRD is examined by the empirical orthogonal function (EOF) analysis, featured as less HD occurrence before 1980 and more occurrence after 2000...

Central factors negatively affect the functional capacity of Fontan patients (FP), but "non-cardiac" factors, such as pulmonary function, may contribute to their exercise intolerance. We studied the pulmonary function in asymptomatic FP and its correlations with their functional capacity. Pulmonary function and cardiopulmonary exercise tests were performed in a prospective study of 27 FP and 27 healthy controls (HC). Cardiovascular magnetic resonance was used to evaluate the Fontan circulation. The mean age at tests, the mean age at surgery, and the median follow-up time of FP were 20(±6), 8(±3), and 11(8-17) years, respectively...

BACKGROUND: Alpha-1 antitrypsin deficiency (AATD) is a rare genetic condition predisposing individuals to chronic obstructive pulmonary disease (COPD). The treatment is generally extrapolated from COPD unrelated to AATD; however, most COPD trials exclude AATD patients; thus, this study sought to systematically review AATD-specific literature to assist evidence-based patient management. METHODS: Standard review methodology was used with meta-analysis and narrative synthesis (PROSPERO-CRD42015019354)...
