Novel functions of o-cymen-5-ol nanoemulsion in reversing colistin resistance in multidrug-resistant Klebsiella pneumoniae infections.

Multidrug resistance (MDR) Klebsiella pneumoniae (K. pneumoniae) is a major emerging threat to human health, and leads to very high mortality rate. The effectiveness of colistin, the last resort against MDR Gram-negative bacteria, is significantly compromised due to the widespread presence of plasmid- or chromosome-mediated resistance genes.

Association between tonsillectomy and risk of oropharyngeal cancer: a systematic review.

Objective: Studies have demonstrated that tonsillectomy may alter the risk of oropharyngeal cancer (OPC). We systematically reviewed the evidence and pooled data to examine such an association.

Methods: PubMed, Embase, and Scopus were searched up to 25 April 2023.

Eight In. Wafer-Scale Epitaxial Monolayer MoS.

Large-scale, high-quality, and uniform monolayer molybdenum disulfide (MoS) films are crucial for their applications in next-generation electronics and optoelectronics. Epitaxy is a mainstream technique for achieving high-quality MoS films and is demonstrated at a wafer scale up to 4-in. In this study, the epitaxial growth of 8-in.

Structural characterization, antioxidant activity and anti-inflammatory of the phosphorylated polysaccharide from .

In this study, a novel polysaccharide (SPN) was extracted by high-temperature pressure method and purified by a DEAE-52 column and a Sephadx G-100 gel column. PPN was obtained after phosphorylation of SPN. The differences of structural features, antioxidant activity, and anti-inflammatory effect of the two polysaccharides were investigated by chemical methods and RAW 264.

[Genetic diversity and genetic relationship of Jatropha curcas L. in Sichuan and Yunnan evaluated by cpSSR markers].

Objective: The genetic diversity and genetic relationship of Jatropha curcas resources in Sichuan and Yunnan were studied in order to provide a theoretical basis for breeding fine varieties and protecting germplasm resources.

Method: Ten J. curcas populations were studied by 12 cpSSR primers in this paper.

Ultra-abrupt tapered fiber Mach-Zehnder interferometer sensors.

A fiber inline Mach-Zehnder interferometer (MZI) consisting of ultra-abrupt fiber tapers was fabricated through a new fusion-splicing method. By fusion-splicing, the taper diameter-length ratio is around 1:1, which is much greater than those (1:10) made by stretching. The proposed fabrication method is very low cost, 1/20-1/50 of those of LPFG pair MZI sensors.

[SHENG MAI ZHUSHEYE improves the viability and movement parameters of human sperm in vitro].

Objective: To observe the effect of SHENG MAI ZHUSHEYE on the movement parameters and viability of human sperm in vitro.

Methods: We collected sperm samples from 33 normal fertile men, divided each into two, and cultured them in vitro with SHENG MAI ZHUSHEYE + Hams-F10 and Hams-F10 alone, respectively. Then we measured the straight line velocity (VSL), curvilinear velocity (VCL), average path velocity (VAP) and the amplitude of lateral head displacement (ALH) of the sperm by computer-aided semen analysis at 0.

[Prevalence of bacterial vaginosis in married women of reproductive age in the rural area of Shandong province and its risk factors].

Objective: To explore the prevalence of bacterial vaginosis of married women of reproductive age in the rural area of Shandong province and its affecting factors, with an aim to provide references for setting up preventing measures for this disease.

Methods: A stratified, population-based, cluster sampling method was employed. The epidemiological investigation on bacterial vaginosis of married women of reproductive age was carried out at four sampling fields.
