Article Synopsis
  • - The study investigates the bacteria in the mucosal tissue surrounding recurrent colorectal polyps, which are pre-cancerous growths, as current treatments mainly involve removal without understanding the underlying biology.
  • - It involved collecting mucosal samples from patients with different types of polyps and healthy individuals, using advanced sequencing techniques to analyze bacterial diversity and patterns.
  • - Results showed that patients with polyps had lower levels of beneficial probiotics and higher levels of harmful bacteria, indicating a potential link between bacterial composition and colorectal polyp development, with age and gender also influencing these bacterial profiles.

Unlabelled: With its estrogenic activity, ()-equol plays an important role in maintaining host health and preventing estrogen-related diseases. Exclusive production occurs through the transformation of soy isoflavones by intestinal bacteria, but the reasons for variations in ()-equol production among different individuals and species remain unclear. Here, fecal samples from humans, pigs, chickens, mice, and rats were used as research objects.

Introduction: Currently, there still are no selection criteria for endoscopic resection (ER) versus laparoscopic resection (LR) of gastric gastrointestinal stromal tumours (GIST) (2 to 4 cm) originating from the muscularis propria layer (MP-GISTs).

Aim: To investigate and compare the long-term prognosis of ER and LR for resecting gastric MP-GISTs, with at least 5 years of follow-up.

Material And Methods: Between January 2010 and December 2015, 134 patients with gastric MP-GISTs were consecutively enrolled in this study.

Article Synopsis
  • The study reviews various literatures and quality standards on Succus Bambusae, highlighting its rich chemical makeup including volatile ingredients, amino acids, flavonoids, trace elements, and vitamins, which contribute to its medicinal and edible value.
  • It discusses current quality control methods like morphological identification, spectroscopy, and chromatography but notes the low quality standards and lack of safety indicators for Succus Bambusae, which jeopardizes its clinical effectiveness.
  • The paper emphasizes the need for a more sensitive and specific quality evaluation system to enhance the safety and quality of Succus Bambusae and aims to support future improvements in this area.

Chrysanthemum is widely used as a type of edible flower and also considered as the important materials of many beverages in China. Due to the occurrence of diseases and pests, and the lack of regulations for species, frequency, dose of pesticides in Chrysanthemum, pesticides have become one of the main pollutants in Chrysanthemum. The pesticide residues in Chrysanthemum were detected frequently and worth noting.

In patients with chronic kidney disease, the abnormal activation of inflammatory pathways is usually an important factor leading to renal fibrosis and further deterioration of renal function. Finding effective intervention targets of the inflammatory signaling pathway is an important way to treat chronic kidney disease. As a newly discovered lysosomal membrane protein, the correlation between SID1 transmembrane family member 2 (Sidt2) and the inflammatory signaling pathway has not been reported.

Accurate prenatal diagnosis of complex congenital cardiovascular anomalies, vascular ones in particular, is still challenging. A fetal cardiovascular cast model can provide a copy of the cardiac chambers and great vessels with normal or pathological structures. This study was aimed to demonstrate three-dimensional anatomy of complex congenital cardiovascular anomalies in fetuses by means of corrosion casting.

Bacterial surface proteins can be good vaccine candidates. In the present study, we used polyclonal antibodies purified with intact to screen phage-displayed random dodecapeptide and loop-constrained heptapeptide libraries, which led to the identification of mimotopes. Homology search of the mimotope sequences against -encoded ORF sequences revealed 14 new antigens that may localize on the surface of .

To investigate the application and effectiveness of vascular corrosion technique in preparing fetal cardiovascular cast models, 10 normal fetal heart specimens with other congenital disease (control group) and 18 specimens with severe congenital heart disease (case group) from induced abortions were enrolled in this study from March 2013 to June 2015 in our hospital. Cast models were prepared by injecting casting material into vascular lumen to demonstrate real geometries of fetal cardiovascular system. Casting effectiveness was analyzed in terms of local anatomic structures and different anatomical levels (including overall level, atrioventricular and great vascular system, left-sided and right-sided heart), as well as different trimesters of pregnancy.

A random 12-peptide library was screened against Erysipelothrix rhusiopthiae and porcine circovirus 2 recombinant Cap protein and the selected peptides were used for detecting the corresponding pathogens quickly and effectively. To our surprise, seven peptides, P1 (WHWNAP WWNGVY), P2 (FHWTWQFPYTST), P3 (GAMHLPWHMGTL), P4 (HWNIWWQHHPSP), P5 (HFFKWHTRTNDQ), P6 (HFFRWHPSAHLG) and P7 (HFAYWWNGVRGP) with the characteristics of polystyrene plate (PS) binding target-unrelated peptides (TUPs), were selected from the library. It has been found that P2 and P4 shared common motif of plastic binding peptide, moreover, P2, P3, P5 and P7 have been isolated repeatedly in other research groups using different targets.

Blood samples were collected from patients with leukemia (n = 150) or lymphoma (n = 150) in the Cancer Hospital from March to September 2014. The specific antibodies (IgG, IgM) to, and circulating antigens (CAg) of Toxoplasma gondii were determined by ELISA. A 529 bp specific sequence was amplified by PCR from the genomic DNA of T.

Capsid protein (Cap), the only structural protein of porcine circovirus 2 (PCV2), is involved in the host protective response and is a target for vaccine development. To find a rapid and easy way to fully map the antigenic epitopes of Cap, purified Cap-specific polyclonal antibodies were used to screen a random heptapeptide phage display library. After three rounds of screening, twenty phage clones that had binding activity to Cap-specific antibodies (tested by phage ELISA) were sequenced.

Outbreaks of classical swine fever (CSF) have caused serious economic consequences in China. Phylogenetic analysis based on full-length E2 gene sequences showed that five classical swine fever virus (CSFV) isolates collected from Hunan province in 2011 and 2012, together with seven other isolates from neighboring provinces, Guangdong (5) and Guangxi (2), could be classified as a new subgenotype 2.1c, which may have been endemic in the south of China for at least fourteen years.

Background: Urethral reconstruction for both congenital and acquired etiologies remains a challenge for most urologic surgeons. Tissue engineering has been proposed as a strategy for urethral reconstruction. The purpose of this study was to determine whether a naturally derived extracellular matrix substitute developed for urethral reconstruction would be suitable for urethral repair in an animal model.
