The operation of membrane-based reactors is inevitably challenged by fouling. The driving force in these reactors is not only critical for water passage through membranes but also significantly influences fouling, such as biocake formation. This study investigated the differences between biocakes formed under transmembrane pressure (TMP) and forward osmosis (FO) conditions, specifically focusing on their components, spatial structures, and microbial communities.

We analyzed the structure and spatiotemporal distribution characteristics of the functional feeding groups of macroinvertebrates, and evaluated river water quality. A total of 73 macroinvertebrate species were collected in the basin, belonging to 42 families, 7 classes, and 3 phyla.

Deliverymen need to complete a large number of delivery orders in limited default time every day, which cause high working stress to them. Therefore, a high level of traffic violations and crashes by deliverymen and corresponding negative impact on public safety are observed.

However, progress is limited due to the complexity of expressway engineering and application limitations of information technology. Design and delivery are still dominated by paper files, and the management of test and inspection data is still relatively extensive.

However, the factors that affect the innovation and development of cities lack systematic analysis as well as interaction analysis. Based on a multidimensional perspective, this study suggests that natural, economic, and social factors are three major factors conditioning urban innovation and development.

According to the ratio of 1∶1∶1, a total of 144 patients were randomly divided into Reyanning Mixture group(RYN), Reyanning Mixture+Amoxicillin Capsules group(RYN+Amoxil) and Amoxicillin Capsules group(Amoxil), with 48 cases in each group, in order to evaluate the efficacy and safety of RYN alone or combined with Amoxil in the treatment of acute tonsillitis, and provided high-quality evidences for treatment of infectious diseases with traditional Chinese medicine and reduced use of antibiotics. The dosage of RYN was 20 mL, 3 times a day, 100 mL/bottle, oral for 7 days, and Amoxil dosage was 0.

However, there is still a debate about the existence of such a process in activated sludge systems. This work provides evidence and elucidated the feasibility of autotrophic Fe(II)-oxidizing nitrate-reducing culture for nitrogen removal by long-term reactor operation, batch experimental verification, unstructured kinetic modeling and microbial community analyses.
View Article and Find Full Text PDFA novel scaffold of arylpiperazine derivatives was discovered as potent androgen receptor (AR) antagonist through rational drug designation based on our pre-work, leading to the discovery of a series of new antiproliferative compounds. Compounds 10, 16, 27, 29 and 31 exhibited relatively strong antagonistic potency against AR and exhibited potent AR binding affinities, while compounds 5, 6, 10, 14, 16, 19, 21, 27 and 31 exhibited strong cytotoxic activities against LNCaP cells (AR-rich) as well as also displayed the higher activities than finasteride toward PC-3 (AR-deficient) and DU145 (AR-deficient). Docking study suggested that the most potent antagonist 16 mainly bind to AR ligand binding pocket (LBP) site through hydrogen bonding interactions.

This study characterized a novel type II crustin, SpCrus2, in the mud crab Scylla paramamosain. The SpCrus2 cDNA sequence is 620-bp long with a 495-bp open reading frame encoding a 164-amino acid protein.
View Article and Find Full Text PDFLysozymes are widely distributed immune effectors exerting muramidase activity against the peptidoglycan of the bacterial cell wall to trigger cell lysis. However, some invertebrate-type (i-type) lysozymes deficient of muramidase activity still exhibit antimicrobial activity. To date, the mechanism underlying the antimicrobial effect of muramidase-deficient i-type lysozymes remains unclear.

BTF could be successfully started up within only 11 days when the inlet concentrations of DMS and PT were both 50 mg·m and EBRT was 30 s, with 90% removal efficiency (RE) of DMS and 100% RE of PT.

In this study, we characterized a novel ALF homolog SpALF6 from mud crab Scylla paramamosain and its variant SpALF6-V, which was generated by mutations of two amino acids (H46 to R and A110 to P) due to the presence of two single nucleotide polymorphisms (SNPs). SpALF6 was an anionic peptide with isoelectric point (pI) 6.

Objective: To understand the status of echinococcosis in Maqing County of Qinghai Province in order to facilitate echinococcosis control in this region.
Methods: Ultrasonic scanning and indirect hemagglutination assay were used to detect echinococcosis infection in residents >1 year old, according to the People's Republic of China Health Industry Standard--Diagnostic Criteria for Hydatid Disease (WS257-2006). Meanwhile, ELISA was used o detect the Echinococcus antigen in dog's feces collected in Youyun, Dangluo and Xiadawu townships.
Background: The 2009 pandemic H1N1 (pH1N1) influenza showed that relatively young adults accounted for the highest rates of hospital admission and death. In preparation for pH1N1, the aim of the study is to identify factors associated with the mortality of patients with 2009 pH1N1 infection, especially for young patients without chronic medical conditions.
Methods: Retrospective observational study of 2151 severe or critical adult cases (≥ 14 years old) admitted to a hospital with pH1N1 influenza from September 1, 2009 to December 31, 2009 from 426 hospitals of 27 Chinese provinces.
Background: 2009 pandemic H1N1 (pH1N1) influenza posed an increased risk of severe illness among pregnant women. Data on risk factors associated with death of pregnant women and neonates with pH1N1 infections are limited outside of developed countries.
Methods: Retrospective observational study in 394 severe or critical pregnant women admitted to a hospital with pH1N1 influenza from Sep.
Background: The complications of systemic inflammatory response syndrome (SIRS) include acute lung injury, acute kidney injury, shock, and multiple organ dysfunction syndrome (MODS). In recent years, how to clear inflammatory mediators has become a hot topic in critical care medicine. Researchers hypothesize that continuous blood purification (CBP) can effectively eliminate a variety of inflammatory mediators which participate in the occurrence of MODS and adjust the immune imbalance.
