BiOI/BiMoO p-n Junction to Enhance Visible Light Photocatalytic Activity toward Environmental Remediation.

Photocatalytic degradation of organic pollutants via semiconductors with high visible light response and effective carrier separation is an economical and green route to greatly achieve environmental remediation. Herein, an efficient BiOI/BiMoO p-n heterojunction was in situ fabricated through hydrothermal method by substituting MoO species for I ions. The characteristic p-n heterojunction exhibited a strongly enhanced visible light responsive absorption from 500 to 700 nm owing to the narrow band gap of BiOI and a greatly effective separation of photoexcited carriers because of the built-in electric field on the interface between BiOI and BiMoO.

The protective immunity induced by intranasally inoculated serotype 63 chimpanzee adenovirus vector expressing human respiratory syncytial virus prefusion fusion glycoprotein in BALB/c mice.

Human respiratory syncytial virus (RSV) is a ubiquitous pediatric pathogen causing serious lower respiratory tract disease worldwide. No licensed vaccine is currently available. In this work, the coding gene for mDS-Dav1, the full-length and prefusion conformation RSV fusion glycoprotein (F), was designed by introducing the stabilized prefusion F (preF) mutations from DS-Cav1 into the encoding gene of wild-type RSV (RSV) F protein.

Antenatal Iron-Rich Food Intervention Prevents Iron-Deficiency Anemia but Does Not Affect Serum Hepcidin in Pregnant Women.

Background: Limited evidence supports the efficacy of iron-rich foods (IRFs) in improving iron status during pregnancy.

Objectives: The study aims to evaluate the effect of IRFs on iron status and biomarkers of iron metabolism in the third trimester of pregnancy.

Methods: A total of 240 pregnant women at 11-13 wk of gestation without iron-deficiency anemia (IDA) in South China were recruited to this single-blind clinical trial [non-IDA referred to both hemoglobin (Hb) ≥110g/L and serum ferritin (SF) ≥15ng/mL],  randomly assigned to 1) control, 2) IRFs containing 20 mg iron/d (IRF-20), or 3) IRFs containing 40 mg iron/d (IRF-40).

Single-course antenatal corticosteroids is related to faster growth in very-low-birth-weight infant.

Background: Antenatal corticosteroids (ACS) treatment is critical to support survival and lung maturation in preterm infants, however, its effect on feeding and growth is unclear. Prior preterm delivery, it remains uncertain whether ACS treatment should be continued if possible (repeated course ACS), until a certain gestational age is reached. We hypothesized that the association of single-course ACS with feeding competence and postnatal growth outcomes might be different from that of repeated course ACS in very-low-birth-weight preterm infants.

Acetylresveratrol as a Potential Substitute for Resveratrol Dragged the Toxic Aldehyde to Inhibit the Mutation of Mitochondrial DNA.

The aim of this study was to explore whether or not acetylresveratrol as a potential substitute for resveratrol dragged the toxic aldehyde to inhibit the mutation of mitochondrial DNA. The results revealed that the acetylresveratrol shifted ultraviolet peak of trans-crotonaldehyde from 316 to 311 nm. In mitochondria, the acetylresveratrol split the ultraviolet peak at 311 nm of trans-crotonaldehyde into 311 nm and 309 nm; the aldehyde Raman band of trans-crotonaldehyde was red shifted by the acetylresveratrol from 1689 to 1686 cm with obvious band decline; Raman bands at 1149 cm, 1168 cm, and 1325 cm of acetylresveratrol disappeared.

Successful revascularization of right coronary artery chronic total occlusion by the antegrade and retrograde approaches.

The treatment of chronic total occlusion (CTO) of coronary arteries allowed for a remarkable improvement in success rates and is represented by the introduction of the "Hybrid algorithm". An inability to cross the occlusion with a guidewire is the most common cause of failure of CTO revascularization. As antegrade options are limited, intervention upon the extreme angulation of the coronary artery warrants a retrograde approach.

Doubled haploid production in alfalfa (Medicago sativa L.) through isolated microspore culture.

Rapid production of doubled haploids (DHs) through isolated microspore culture is an important and promising method for genetic study of alfalfa. To induce embryogenesis in alfalfa, isolated microspores were submitted to abiotic stresses during their initial culture, in order to stimulate them to form embryos and plantlets. 'Baoding' and 'Zhongmu No 1' alfalfa cultivars supported reproducible and reliable proliferation response irrespective of any stress treatment of microspores.

Toxic trans-crotonaldehyde in mitochondria intercepted by oxyresveratrol contributing to anticancer.

The aim of this study was to explore how the toxic trans-crotonaldehyde (TCA) in mitochondria or aldehyde dehydrogenase (ALDH) at different pHs was intercepted by oxyresveratrol (Oxy-Res) contributing to anticancer. Ultraviolet-visible (UV-vis) spectroscopy and Raman spectroscopy were employed. UV-vis spectra showed that the Oxy-Res red shifted the peak of the toxic TCA from 316 nm to 325 nm, while the peaks of the Oxy-Res shifted from 329 nm with 290 nm and 300 nm to 325 nm with 303 nm.

Latent role of in vitro Pb exposure in blocking Aβ clearance and triggering epigenetic modifications.

Both β-amyloid (Aβ) catabolism and epigenetic regulation play critical roles in the onset of neurodegeneration. The latter also contribute to Pb neurotoxicity. The present study explored the role of epigenetic modifiers and Aβ degradation enzymes in Pb-induced latent effects on Aβ overproduction in vitro.

Toxic target of trans-crotonaldehyde in mitochondria altered by diallyl disulfides for anti-myocardial ischemia.

The purposes of this study were to probe spectral behaviors of the toxic targets in trans-crotonaldehyde (TCA) in mitochondria altered by diallyl disulfides (DADS) derived from garlic. Ultraviolet absorption spectra showed that when ethanol as a solvent, the DADS blue shifted the peak of TCA from 318 nm to 312 nm. In mitochondria, the DADS further blue displaced the peak of TCA from 312 nm to 308 nm.

Effect of lithocholic acid on biologically active α,β-unsaturated aldehydes induced by H2O2 in glioma mitochondria for use in glioma treatment.

Lithocholic acid (LCA) is known to kill glioma cells while sparing normal neuronal cells. However, the anti-glioma mechanism of LCA is unclear at present. Although malondialdehyde (MDA) is not specific to detect tumors, biologically active α,β-unsaturated aldehydes can be used to detect the outcome of gliomas, especially the mitochondria, as a research tool.

Influences of ethanol on the structure of toxic trans-crotonaldehyde in mitochondria coming from rat myocardium.

Inappropriate use of ethanol (EtOH) had led to noticeable health problems, but a beneficial phenomenon was found that EtOH displayed unique influences for toxic trans-crotonaldehyde (TCA) derived from mitochondrial lipid peroxidation. The influences of EtOH on the structure of TCA were systematically probed by UV-vis & Raman spectroscopy in the absence and presence of mitochondria, respectively. The maximum UV-vis peak at 301 nm of TCA was red shifted by hydroxyl (-OH) and methyl (-CH) of EtOH, respectively.

Spectroscopic evidences of toxic trans-crotonaldehyde trapped and transformed by resveratrol to prevent the damage of mitochondrial DNA.

The purpose of this study is to probe the spectroscopic evidences of toxic trans-crotonaldehyde (TCA) trapped and transformed by resveratrol (Res) to prevent the damage of mitochondrial DNA. In aldehyde dehydrogenase (ALDH) at the different pH or mitochondria, the spectroscopic characteristics of TCA trapped and transformed by Res were observed by means of both UV-vis and Raman spectra. When Res interacted with TCA, TCA peak at 316 nm immediately disappeared while Res main peak at 305 nm and shoulder peak at 320 nm were dramatically changed, Raman peaks of TCA at 1,688 cm assigned to CHO and 1,641 cm affiliated to CC were strikingly shifted, Raman peaks of Res itself were significantly displaced or disappeared, especially in mitochondria and ALDH at different pH.

Chromosome Doubling of Microspore-Derived Plants from Cabbage (Brassica oleracea var. capitata L.) and Broccoli (Brassica oleracea var. italica L.).

Chromosome doubling of microspore-derived plants is an important factor in the practical application of microspore culture technology because breeding programs require a large number of genetically stable, homozygous doubled haploid plants with a high level of fertility. In the present paper, 29 populations of microspore-derived plantlets from cabbage (Brassica oleracea var. capitata) and broccoli (Brassica oleracea var.

QTL Analysis of Head Splitting Resistance in Cabbage (Brassica oleracea L. var. capitata) Using SSR and InDel Makers Based on Whole-Genome Re-Sequencing.

Head splitting resistance (HSR) in cabbage is an important trait closely related to both quality and yield of head. However, the genetic control of this trait remains unclear. In this study, a doubled haploid (DH) population derived from an intra-cross between head splitting-susceptible inbred cabbage line 79-156 and resistant line 96-100 was obtained and used to analyze inheritance and detect quantitative trait loci (QTLs) for HSR using a mixed major gene/polygene inheritance analysis and QTL mapping.
