Background: This study is aimed at analyzing the changes in gut microorganism of patients with positive immune antibody-associated recurrent abortion using the 16s rRNA gene sequencing microbiome assay.

Methods: The fecal samples from 20 recurrent abortion women with positive immune antibody (positive group) and 20 with negative immune antibody (negative group) were collected. After 16s rRNA gene sequencing, the obtained raw reads underwent quality filtering to obtain the clean tags and then classified into microbial genomes.

Background: Thrombotic thrombocytopenic purpura (TTP), a subtype of thrombotic microangiopathy, has a very high fatality rate if there is no timely diagnosis or treatment. Here, we report a case of TTP refractory to high displacement plasma exchange, which was later successfully treated with rituximab.

Case Summary: Here we report a case of refractory TTP in a 63-year-old woman with a low platelet count and decreased ADAMTS13 activity.

Acrolein, known as one of the most common reactive carbonyl species, is a toxic small molecule affecting human health in daily life. This study is focused on the scavenging abilities and mechanism of ferulic acid and some other phenolic acids against acrolein. Among the 13 phenolic compounds investigated, ferulic acid was found to have the highest efficiency in scavenging acrolein under physiological conditions.

Pasteurella multocida can infect a wide range of host, including humans and animals of economic importance. Genomics studies on the pathogen have produced a large amount of omics data, which are deposited in GenBank but lacks a dedicated and comprehensive resource for further analysis and integration so that need to be brought together centrally in a coherent and systematic manner. Here we have collected the genomic data for 176 P.

In the present study, we evaluated the impact of sperm origins and concentration on the clinical outcomes of intracytoplasmic sperm injection (ICSI) cycles. A total of 1201 ICSI cycles were retrospectively analyzed for male azoospermia or oligozoospermia between January 2015 and December 2015 in the Peking University Third Hospital. Patients were divided into three groups (Group 1 vs Group 2/3; surgically extracted sperm vs ejaculated sperms): Group 1 included 343 ICSI cycles and Group 2 analyzed 388 cycles on semen with sperm concentration <5 × 10 ml (severe oligozoospermia group).

This study developed a partial nitrification (PN) and anaerobic ammonia oxidation (Anammox) process for treating high-ammonia wastewater using an innovative biofilm system in which ammonia oxidizing bacteria grew on fluidized Kaldnes (K1) carriers and Anammox bacteria grew on fixed acryl resin carriers. The airlift loop biofilm reactor (ALBR) was stably operated for more than 4 months under the following conditions: 35 ± 2 °C, pH 7.5-8.

A hybrid drug delivery system was successfully fabricated by attaching a camptothecin (CPT)-based polymeric prodrug onto the surface of silver nanoparticles (AgNPs). PEG was employed as a macro-RAFT agent in RAFT polymerization to synthesize a branched star copolymer, to which CPT is linked through the photo-responsive o-nitrobenzyl linkage. In vitro tests indicate that the fluorescence of CPT in the polymeric prodrug is quenched by AgNPs based on the nanomaterial surface energy transfer (NSET) effect and the fluorescence recovers when the CPT molecules are released from hybrid nanoparticles.

Background: Anterior temporal lobectomy (ATL) is the standard surgical treatment for temporal lobe epilepsy (TLE), but patients may suffer from recurrent seizures post-surgery. Invasive electrical monitoring plays a critical role in precisely identifying the epileptic foci. This study aimed to evaluate and compare the benefits of long-term invasive electroencephalography (EEG) monitoring and two-stage surgery with the classical approach to examine their effect on post-surgical brain function and complications.

Our study aims to evaluate the efficacy of transcatheter arterial chemoembolization in the treatment of patients with liver metastasis using integrated F-fluorodeoxyglucose positron emission tomography/computed tomography. A total of 97 liver metastasis patients treated by transcatheter arterial chemoembolization were enrolled in this study. The F-fluorodeoxyglucose positron emission tomography/computed tomography images of liver metastasis patients were collected before and after transcatheter arterial chemoembolization treatment.

Unlabelled: Silkworm pathogens have been heavily impeding the development of sericultural industry and play important roles in lepidopteran ecology, and some of which are used as biological insecticides. Rapid advances in studies on the omics of silkworm pathogens have produced a large amount of data, which need to be brought together centrally in a coherent and systematic manner. This will facilitate the reuse of these data for further analysis.

Article Synopsis
  • - The study aimed to investigate the relationship between liver fibrosis levels and biochemical parameters in patients with advanced schistosomiasis using liver biopsy and B ultrasound imaging.
  • - Among 48 patients, the findings showed no correlation between liver fibrosis levels from biopsy and biochemical parameters, but a weak correlation was seen with ultrasound and certain biochemical markers like GGT, AKP, LN, and PC-III.
  • - The results suggest that B ultrasound is a more effective noninvasive way to assess liver fibrosis, and when combined with specific biochemical markers, it provides a clearer picture of liver health.

Vibroacoustic disease, a progressive and systemic disease, mainly involving the central nervous system, is caused by excessive exposure to low-frequency but high-intensity noise generated by various heavy transportations and machineries. Infrasound is a type of low-frequency noise. Our previous studies demonstrated that infrasound at a certain intensity caused neuronal injury in rats but the underlying mechanism(s) is still largely unknown.
