Sodium cyclamate in Baijiu is a key item in the China National Food Safety Supervision and Inspection Plan. A simple, economical, sensitive, and reliable method is urgently needed for routine analysis and internal quality control. A method based on high performance liquid chromatography with fluorescence detection (HPLC-FLD) was developed for the determination of sodium cyclamate in Baijiu by -phthalaldehyde derivatization.

In such cases, early supplemental feeding is particularly important to meet the growth needs of the foal. Foals have an incompletely developed gastrointestinal tract with a homogenous microbiota and produce insufficient amounts of digestive enzymes, which limit their ability to digest and utilize forage.

Purpose: To integrate digital dynamic smile aesthetic simulation (DSAS) cognitive education in orthodontic practicum and evaluate the teaching effects.
Methods: A total of 32 dental students during orthodontic practicum were randomly divided into two groups. One group received traditional teaching method to draft treatment plan, and another group was implemented with DSAS teaching method.
Three unprecedented ent-labdane and pallavicinin based dimers pallamins A-C formed via [4 + 2] Diels-Alder cycloaddition, together with eight biosynthetically related monomers were isolated from Pallavicinia ambigua. Their structures were determined by the extensive analysis of HRESIMS and NMR spectra. The absolute configurations of the labdane dimers were determined by single crystal X-ray diffraction of the homologous labdane units, and C NMR and ECD calculations.

PEComas that originate in the bladder are extremely rare clinically, with only 35 cases reported in the English literature thus far. Here, we report a case of bladder PEComa resection by transurethral en bloc resection of bladder tumor (ERBT).

Due to the complexity of the microbes in the stomach, little is known about the diversity and structure of bacteria in the equine stomach. Grains are the main energy source for plant-eating livestock and energy is derived through enzymatic hydrolysis of grains into glucose or their microbial fermentation into Volatile fatty acids (VFA).

Methods: CCK-8, wound healing assay, Transwell, and cell cycle assay were used to detect the tumor cells development. Cell viability was assessed by MTT.
Introduction: To assess the prophylactic effect of simultaneous placement of mesh and the incidence of parastomal hernia (PSH) after abdominoperineal resection of rectal cancer.
Methods: This study included real-world data of 56 surgically resected patients with colorectal cancer who were consecutively assigned to two groups: control (no mesh, n = 32) and experimental (received mesh, n = 24). An artificial patch was placed under the tunica vaginalis of rectus abdominis for patients in the experimental group, whereas those in the control group received routine sigmoidostomy.
Background: Eosinophilic cystitis (EC) is a rare inflammatory disease characterized by the gathering and infiltration of numerous eosinophilia (EOS) in the bladder wall. Because of Few cases of EC have been reported globally, the epidemiology of EC is not well known. We report herein the details of one very scarce case of large tumor-like eosinophilic cystitis complicated with cystitis glandularis (CG) diagnosed by biopsy.

Methods: A total of 167 patients with malignant tumors who received double J stent indwelling in the hospital from January 2018 to January 2021 were included in the study. The urine and double J stent samples were collected for bacterial identification and observed for BF formation on the surface of the urinary catheter under a scanning electron microscope (SEM).
Background: There is little objective information concerning the effect of steam-flaked grains on foal's growth performance and faecal microbiota. To determine the effects of steam-flaked grains on foal's growth performance and faecal microbiota, faecal samples were collection from 18 foals which had been fed either corn, oat or barley diets over the 60 days of the experiment. Body weight and conformation measurements were collected.

Phragmites australis and Chloris virgata are native, dominant, salt-tolerant grass species that grow in the Yellow River Delta, China, and have potential applications in the phytoremediation of petroleum-polluted saline soil. The characteristics of endophytic bacterial communities of Phragmites australis and Chloris virgata and their functions in hydrocarbon degradation and plant growth promotion have been studied using both high-throughput sequencing and conventional microbial techniques. Through 16S rRNA gene amplicon sequencing, we found five bacterial phyla that were dominant among the endophytic bacterial communities of the two grass species, including Proteobacteria, Actinobacteria, Firmicutes, Bacteroidetes, and Tenericutes.

The flow of viscoelastic fluid in a micro cross-slot with a high channel aspect ratio (, the ratio of channel depth to width) can be divided into three types, which are symmetric flow, steady-state asymmetric flow and time-dependent flow under the inlet condition with a constant velocity. However, the flow pattern of a viscoelastic fluid in the cross-slot when a stimulation is applied at inlets has been rarely reported.
