Investigation of aerosol and gas emissions from a coal-fired power plant under various operating conditions.

The concentrations of fine particles and selected gas pollutants in the flue gas entering the stack were measured under several common operation modes in an operating coal power plant producing electricity. Particle size distributions in a diameter range from 10 nm to 20 μm were measured by a scanning mobility particle sizer (SMPS), and the flue gas temperature and concentrations of CO and SO were monitored by a continuous emission monitoring system (CEMS). During the test campaign, five plant operating modes were studied: soot blowing, bypass of flue-gas desulfurization (FGD), reheat burner operating at 0% (turned off), 27%, and 42% (normal condition) of its full capacity.

Effects of small-dose remifentanil combined with index of consciousness monitoring on gastroscopic polypectomy: a prospective, randomized, single-blinded trial.

Background: With the development of painless diagnosis and treatment, remifentanil, a synthetic opioid agonist, is increasingly used in gastroscopy for its rapid, short-term, and potent analgesic effect. However, the dosage of remifentanil used in endoscopy is unclear. Index of consciousness (IOC) is a new anesthesia depth-monitoring indicator that can be divided into index of consciousness 1 (IOC) and index of consciousness 2 (IOC); IOC is used for estimating a patient's sedation state, whereas IOC reflects analgesic depth.

Methionine attenuates the intensity of rheumatoid arthritis by downregulating NF-κB and iNOS expression in neonatal rats.

The present study investigated the anti-arthritic effects of methionine in neonatal rats. Rats were divided into four groups, with six rats in each group. The rats were administered methionine (150- or 300-mg/kg body weight) orally for 45 consecutive days.

Application of the space-resolving flux detector for radiation measurements from an octahedral-aperture spherical hohlraum.

Space-resolving flux detection is an important technique for the diagnostic of the radiation field within the hohlraum in inertial confinement fusion, especially for the radiation field diagnostic in the novel spherical hohlraum with octahedral six laser entrance holes (LEHs), where localized measurements are necessary for the discrimination of the radiation flux from different LEHs. A novel space-resolving flux detector (SRFD) is developed at the SG-III laser facility for the radiation flux measurement in the first campaign of the octahedral spherical hohlraum energetics experiment. The principle and configuration of the SRFD system is introduced.

GnRH agonist improves pregnancy outcome in mice with induced adenomyosis by restoring endometrial receptivity.

Purpose: Adenomyosis has a negative impact on female fertility. GnRH agonist treatment can improve pregnancy outcomes in women with adenomyosis. However, the impact of GnRH agonist upon endometrium receptivity of patients with adenomyosis remains unclear.

Preincubation with glutathione ethyl ester improves the developmental competence of vitrified mouse oocytes.

Purpose: Oocyte vitrification is currently used for human fertility preservation. However, vitrification damage is a problem caused by decreasing ooplasmic levels of glutathione (GSH). The GSH donor glutathione ethyl ester (GSH-OEt) can significantly increase the GSH content in oocytes.

Increased mitochondrial fission is critical for hypoxia-induced pancreatic beta cell death.

Hypoxia-mediated pancreatic beta cell death is one of the main causes of pancreatic beta celldeath, which leads to the loss of functional pancreatic beta cell mass and type 1 diabetes andtype 2 diabetes.However, the molecular mechanisms that control life and death of pancreatic beta cells remain poorly understood. Here we showed that mitochondrial fission was strongly induced in pancreatic beta cellsmainly due to an elevation of DRP1S616 phosphorylation through HIF-1αactivation and subsequent DRP1 mitochondrial translocation.

TRPV6 protects ER stress-induced apoptosis via ATF6α-TRPV6-JNK pathway in human embryonic stem cell-derived cardiomyocytes.

Human pluripotent stem cell-derived cardiomyocytes have potential applications in disease modeling and drug screening. Therefore, it is important to understand the mechanisms and signaling pathways underlying the survival and death of these cells. Endoplasmic reticulum (ER) stress is triggered by various cellular stresses that disturb protein folding in the ER.

First Octahedral Spherical Hohlraum Energetics Experiment at the SGIII Laser Facility.

The first octahedral spherical hohlraum energetics experiment is accomplished at the SGIII laser facility. For the first time, the 32 laser beams are injected into the octahedral spherical hohlraum through six laser entrance holes. Two techniques are used to diagnose the radiation field of the octahedral spherical hohlraum in order to obtain comprehensive experimental data.

Reduced-dose EPOCH-R chemotherapy for elderly patients with advanced stage diffuse large B cell lymphoma.

The standard treatment in elderly patients with diffuse large B cell lymphoma (DLBCL) has not yet been finely established. We investigated the efficacy and safety of rituximab with a reduced-dose of EPOCH chemotherapy in elderly patients who had advanced DLBCL with high IPI scores. The dose of 70% EPOCH was given to patients aged 75 to 79 years, and dose of 50% to patients aged over 80 years.

Hypoxia induces endothelial‑mesenchymal transition in pulmonary vascular remodeling.

It is well established that hypoxia induces epithelial‑mesenchymal transition in vitro and in vivo. However, the role of hypoxia in endothelial‑mesenchymal transition (EndMT), an important process in the pathogenesis of pulmonary hypertension, is not well‑characterized. The present study demonstrated a significant downregulation of the endothelial marker CD31 and its co‑localization with a mesenchymal marker, α‑smooth muscle actin (α‑SMA), in the intimal layer of small pulmonary arteries of rats exposed to chronic hypoxia.

Orientation-dependent strong-field dissociative single ionization of CO.

The dissociative ionization of CO in orthogonally polarized femtosecond laser pulses are studied in a pump-probe scheme. The ionization of CO by the pump pulse and the dissociation of the created CO by the probe pulse can be fully disentangled by identifying the photoelectron momentum distributions. Different from the dissociative ionization by a single pulse in which the CO molecule mostly breaks along the field polarization, in this pump-probe strategy, the CO ion created from ionization by the pump pulse is favored to dissociate when it orients orthogonal to the polarization direction of the probe pulse.

Wetlands and Malaria in the Amazon: Guidelines for the Use of Synthetic Aperture Radar Remote-Sensing.

The prevention and control of mosquito-borne diseases, such as malaria, are important health issues in tropical areas. Malaria transmission is a multi-scale process strongly controlled by environmental factors, and the use of remote-sensing data is suitable for the characterization of its spatial and temporal dynamics. Synthetic aperture radar (SAR) is well-adapted to tropical areas, since it is capable of imaging independent of light and weather conditions.

Backscatter spectra measurements of the two beams on the same cone on Shenguang-III laser facility.

In laser driven hohlraums, laser beams on the same incident cone may have different beam and plasma conditions, causing beam-to-beam backscatter difference and subsequent azimuthal variations in the x-ray drive on the capsule. To elucidate the large variation of backscatter proportion from beam to beam in some gas-filled hohlraum shots on Shenguang-III, two 28.5° beams have been measured with the Stimulated Raman Scattering (SRS) time-resolved spectra.

Biosynthesis of gold nanoparticles using cell-free extracts of Magnusiomyces ingens LH-F1 for nitrophenols reduction.

A green and eco-friendly method for the synthesis of gold nanoparticles (AuNPs) was developed using the cell-free extracts of a yeast strain Magnusiomyces ingens LH-F1. UV-vis spectra showed a distinct absorption band at ~ 540 nm, corresponding to the surface plasmon resonance of AuNPs. Transmission electron microscopy images revealed that the shapes of AuNPs were almost spherical and pseudo-spherical.

TM9SF4 is a novel factor promoting autophagic flux under amino acid starvation.

Autophagy is a highly complicated process with participation of large numbers of autophagy-related proteins. Under nutrient starvation, autophagy promotes cell survival by breaking down nonessential cellular components for recycling use. However, due to its high complexity, molecular mechanism of autophagy is still not fully understood.

Automatic regulation of NF-κB by pHSP70/IκBαm to prevent acute lung injury in mice.

Controlling target gene expression is a vital step in the procedure of gene therapy upon acute lung injury (ALI). Excessive activation of nuclear factor-kappa B (NF-κB) has been the key point of the inflammation overwhelming process in onset of ALI. We designed and tested a variety of plasmid named pHSP70/IκBαm which conditionally carries a mutant inhibitor of kappa B (IκB) transgene to regulate the activity of NF-κB signaling pathway in its response to an inflammatory stimulus that causes acute lung injury.

Objective: To analyze the effect of three-dimensional (3D) laparoscopic total thyroidectomy combined with central lymph node dissection for thyroid cancer and its effect on the inflammatory response of the patients.

Methods: The clinical data were analyzed in 90 patients with thyroid cancer undergoing radical thyroidectomy at our hospital between September, 2013 to April, 2016, including 30 receiving 3D laparoscopic surgeries, 30 with 2D laparoscopic surgeries and 30 with open surgeries. The surgical data, postoperative adverse reactions and the impact of the surgeries on the inflammatory responses of the patients were compared among the 3 groups.

Reoxygenation Reverses Hypoxic Pulmonary Arterial Remodeling by Inducing Smooth Muscle Cell Apoptosis via Reactive Oxygen Species-Mediated Mitochondrial Dysfunction.

Background: Pulmonary arterial remodeling, a main characteristic of hypoxic pulmonary hypertension, can gradually reverse once oxygen has been restored. Previous studies documented that apoptosis increased markedly during the reversal of remodeled pulmonary arteries, but the types of cells and mechanisms related to the apoptosis have remained elusive. This study aimed to determine whether pulmonary artery smooth muscle cell (PASMC)-specific apoptosis was involved in the reoxygenation-induced reversal of hypoxic pulmonary arterial remodeling and elucidate the underlying mechanism.

Observing electron localization in a dissociating H molecule in real time.

Dissociation of diatomic molecules with odd number of electrons always causes the unpaired electron to localize on one of the two resulting atomic fragments. In the simplest diatomic molecule H dissociation yields a hydrogen atom and a proton with the sole electron ending up on one of the two nuclei. That is equivalent to breaking of a chemical bond-the most fundamental chemical process.

Gastrodin Inhibits Store-Operated Ca Entry and Alleviates Cardiac Hypertrophy.

Cardiac hypertrophy is a major risk factor for heart failure, which are among the leading causes of human death. Gastrodin is a small molecule that has been used clinically to treat neurological and vascular diseases for many years without safety issues. In the present study, we examined protective effect of gastrodin against cardiac hypertrophy and explored the underlying mechanism.

Experimental demonstration of low laser-plasma instabilities in gas-filled spherical hohlraums at laser injection angle designed for ignition target.

Octahedral spherical hohlraums with a single laser ring at an injection angle of 55^{∘} are attractive concepts for laser indirect drive due to the potential for achieving the x-ray drive symmetry required for high convergence implosions. Laser-plasma instabilities, however, are a concern given the long laser propagation path in such hohlraums. Significant stimulated Raman scattering has been observed in cylindrical hohlraums with similar laser propagation paths during the ignition campaign on the National Ignition Facility (NIF).

Altered microstructure rather than morphology in the corpus callosum after lower limb amputation.

The corpus callosum (CC) has been implicated in the reorganization of the brain following amputation. However, it is unclear which regions of the CC are involved in this process. In this study, we explored the morphometric and microstructural changes in CC subregions in patients with unilateral lower limb amputation.
