[Simultaneous determination of 43 antibacterials from nine categories in water using automatic sample loading-solid phase extraction-ultra performance liquid chromatography-tandem mass spectrometry].

Antibacterials represent a pharmaceutical class that is extensively used and consumed worldwide. The presence of a large number of antibacterial agents in water could result in antibiotic resistance. Thus, the development of a fast, accurate, and high-throughput method to analyze these emerging contaminants in water is necessary.

Three new lanostane-type triterpenes from the epidermis of .

is commonly used as a traditional Chinese medicine for its diuretic, tonifying, and invigorating effects on the spleen. However, the epidermis of is discarded as scrap during harvesting because of its low price, resulting in a great waste of resources and environmental pollution. In this work, the epidermis of was studied and three new lanostane triterpenoids were isolated.

Cellular senescence of renal tubular epithelial cells in renal fibrosis.

Renal fibrosis (RF) is the common pathological manifestation of virtually all chronic kidney diseases (CKD) and one of the major causes of end-stage renal disease (ESRD), but the pathogenesis of which is still unclear. Renal tubulointerstitial lesions have been identified as a key pathological hallmark of RF pathology. Renal tubular epithelial cells are the resident cells of the tubulointerstitium and play an important role in kidney recovery versus renal fibrosis following injury.

The efficacy and feasibility of total reconstruction versus nontotal reconstruction of the pelvic floor on short-term and long-term urinary continence rates after radical prostatectomy: a meta-analysis.

Background: Recently, total pelvic floor reconstruction (TR) has been the treatment of choice for improving urinary incontinence (UI) after radical prostatectomy (RP). However, the superiority of TR with respect to urinary continence recovery following RP remains controversial. This study identified the effect of TR versus nonTR of the pelvic floor on short-term and long-term continence rates after RP.

Prognostic values of clinicopathological characteristics and survival outcomes in prostate infiltrating ductal carcinoma: a population-based study.

Infiltrating ductal carcinoma (IDC) is a rare histologic subtype of prostate cancer. We investigated the clinicopathological features and prognosis of IDC compared with acinar cell carcinoma (ACC). We identified 3814 men diagnosed with prostate cancer between 2004 to and 2013 in the Surveillance, Epidemiology, and End Results database, including 511 IDC and 3303 ACC cases.

[Study of Determination of Oil Mixture Components Content Based on Quasi-Monte Carlo Method].

Gasoline, kerosene, diesel is processed by crude oil with different distillation range. The boiling range of gasoline is 35 ~205 °C. The boiling range of kerosene is 140~250 °C.

[DFT and surface-enhanced Raman scattering studies of BPA].

On the base of the vibration theory, the spectrum of bisphenol A(BPA) molecule was calculated by the density functional theory(DFT) using B3LYP/6-311G(d), and the normal Raman spectrum (NRS) of BPA was assigned in detail. The surface enhanced Raman scattering (SERS) of the BPA molecule was obtained by gold sol enhancement. The adsorption of BPA to gold surface was analyzed: in acidic pH, the molecule was adsorbed on the gold surface by =CO-, the vibration of the band O-H disappeared, and the benzene ring was perpendicular on the surface of gold sol.

Assessment of the antibacterial activity and the antidiarrheal function of flavonoids from bayberry fruit.

Chinese bayberry fruits are used as a folk medicine to cure diarrhea. However, the active compounds have not yet been reported. We found that bayberry fruit extract showed significant antibacterial activity against Salmonella, Listeria, and Shigella, and the minimal inhibitory concentration (MIC) ranged from 2.
