Molecular characterization and antimicrobial susceptibility for 62 isolates of from children.

Background: Pertussis is a highly contagious respiratory disease caused by (BP). Despite global control of pertussis cases through the Expanded Programme on Immunization (EPI), there has been a significant increase in the incidence of pertussis in recent years, characterized by a "resurgence" in developed countries with high immunization rates as well as a comparable reemergence in certain areas of China. We aim to explore the genotypes and antimicrobial susceptibility of circulating BP from children in Hebei.

The First Case of Serogroup Y and An Expanded Investigation of Healthy Carriers - Shijiazhuang City, Hebei Province, China, 2023.

What Is Already Known About This Topic?: (Nm) is a bacterial pathogen that causes meningococcal disease. Serogroups A, B, C, W, X, and Y account for the vast majority of cases. However, invasive meningococcal disease (IMD) caused by NmY is rare in China and has been reported only in Tianjin, Guangdong, Shanghai, and Hunan provinces and cities.

Combined effects of mixing ratios and tree size: how do mixed forests respond to climate and drought events?

Although the relationship between biodiversity and ecosystem functionality (BEF) has been studied comprehensively, how the mixing ratio of tree species in mixed forests affects the response of trees to climate and drought remains an unexplored and rather unknown question. Hence, we established tree-ring chronologies for Carr. (P) and Blume.

Cysteine protease inhibitor of Schistosoma japonicum - A parasite-derived negative immunoregulatory factor.

Studies have shown that cysteine protease inhibitors from some parasites have immunosuppressive effects on the host. We previously have cloned a novel cysteine protease inhibitor from Schistosoma japonicum and purified its recombinant version (protein named rSj-C). Its possible inhibitory effect on the host immune response has not been described.

Inhibitory effect of bone morphogenetic protein-2 on the proliferation of giant cell tumor of bone stromal cells .

The inhibitory effect of bone morphogenetic protein-2 (BMP-2) on the proliferation of giant cell tumor of bone stromal cells (GCTSCs) has not been fully elucidated. Therefore, the aim of this study was to evaluate the role of recombinant human BMP-2 (rhBMP-2) in the growth of GCTSCs. The effects of exposure to different concentrations of rhBMP-2 (0, 10, 100 and 300 ng/ml) for 1, 3, 5 and 7 days on GCTSC proliferation were examined by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay.

Addition of Zn to the ternary Mg-Ca-Sr alloys significantly improves their antibacterial property.

Most of the magnesium (Mg) alloys possess excellent biocompatibility, mechanical property and biodegradability in orthopedic applications. However, these alloys may suffer from bacterial infections due to their insufficient antibacterial capability. In order to reduce the post-surgical infections, a series of biocompatible Mg-1Ca-0.

CC4821 serogroup W meningococcal disease in China.

Neisseria meningitidis is a major public health concern worldwide, including China. A few cases of serogroup W meningococcal disease have been reported in southeast China in recent years. Thus far, invasive disease due to W isolates has involved sequence type 11.

Characterization and expression of a novel cystatin gene from Schistosoma japonicum.

Cystatins are a family of cysteine protease inhibitors that play a crucial role in the immune evasion from their host and in the adaptation to host defence. Here, we isolated a full-length cDNA sequence inferred to encode a novel cystatin gene from a blood fluke, Schistosoma japonicum. The cDNA, designated SjCystatin, comprised an open reading frame (ORF) of 306 bp, and encoded 101 amino acids with a predicted molecular weight of 11.

[Retrieval and validation of the surface reflectance using HJ-1-CCD data].

The potentiality of the retrieval of surface reflectance using CCD camera aboard HJ-1A/B satellite was studied. It is very difficult to use dark targets in atmospheric correction due to the lack of near infrared band. The alternative normalized difference vegetation index (NDVI) and the red/blue reflectance ratio are detected from the spectral experiment in Beijing and the Pearl River Delta.

[Fronto-temporal anatomy and its application for augmentation plasty].

Objective: To decide the safe dissection plane and evaluate the multiple materials used for the fronto-temporal augmentation.

Methods: Clinical anatomical observation were made during the fronto-temporal operations. Forty-one patients were treated for the fronto-temporal augmentation with various granular or patched materials in different anatomical plane.
