A Novel sp. Strain PBSH9 for Controlling Potato Common Scab Caused by .

Potato common scab is an important soilborne disease worldwide that can significantly reduce the quality and economic values of potato. The disease is caused by multiple species of , which are not well controlled due to lack of effective strategies. has been recently identified as a dominant species causing potato common scab in Inner Mongolia, China.

Characterization of Fam20C expression in odontogenesis and osteogenesis using transgenic mice.

Our previous studies have demonstrated that Fam20C promotes differentiation and mineralization of odontoblasts, ameloblasts, osteoblasts and osteocytes during tooth and bone development. Ablation of the Fam20C gene inhibits bone and tooth growth by increasing fibroblast growth factor 23 in serum and causing hypophosphatemia in conditional knockout mice. However, control and regulation of the expression of Fam20C are still unknown.

A single nucleotide polymorphism in the matrix metalloproteinase 2 promoter is closely associated with high risk of nasopharyngeal carcinoma in Cantonese from southern China.

Matrix metalloproteinase 2 (MMP2) has been shown to play an important role in several steps of cancer development. The -1306C/T polymorphism of the MMP2 gene displays a strikingly lower promoter activity than the T allele, and the CC genotype in the MMP2 promoter has been reported to associate with the development of several cancers. To assess the contribution of the MMP2 -1306C/T polymorphism to the risk of nasopharyngeal carcinoma (NPC), we conducted a case-control study and analyzed MMP2 genotypes in 370 patients with NPC and 390 frequency-matched controls using real-time PCR-based TaqMan allele analysis.

Biologic markers for odontogenic periradicular periodontitis.

Introduction: The diagnosis and assessment of apical periodontitis by traditional periapical radiographs can be challenging and might yield false-negative results. The aim of this study was to determine whether interleukin-1beta (IL-1beta) and dentin sialoprotein (DSP) in gingival crevicular fluid (GCF) can be used as biological markers for apical periodontitis.

Methods: Forty healthy patients with teeth diagnosed with apical periodontitis of pulpal origin were included in the study.

[Effects of extract of Bulbus Allii Caespitosi on cardiocyte viability of swines with myocardial reperfusion injury evaluated by (18)F-fluorodeoxyglucose positron emission tomography/computed tomography].

Objective: To investigate the effects of extract of Bulbus Allii Caespitosi on cardiocyte viability of swines with myocardial reperfusion injury by analyzing the 18F-fluorodeoxyglucose ((18)F-FDG) position emission tomography (PET) imaging.

Methods: Twenty-four swines were randomly divided into sham-operated group, untreated group, trimethazine group and extract of Bulbus Allii Caespitosi group. Myocardial reperfusion injury was induced by plugging the anterior descending coronary artery of swine with sacculus.

[Therapeutic effects of Tiaozhong Granule on esophagus mucous membrane in rats with mixed reflux esophagitis and the mechanisms].

Objective: To explore the mechanism of Tiaozhong Granule (TZG), a compound traditional Chinese herbal medicine, in treating rats with mixed reflux esophagitis.

Methods: Fifty-eight SD rats were randomly divided into untreated group (n=12), sham-operated group (n=10), TZG-treated group (n=12), Banxia Xiexin Decoction (BXXXD)-treated group (n=12) and cisapride-treated group (n=12). Mixed reflux esophagitis was induced by esophago-duodenum end-to-side anastomosis.

[Protective effect of Huaxia shallot preparation on human umbilical vein endothelial cell injury induced by oxidized low density lipoprotein and its mechanism].

Objective: To observe the protective effect of Huaxia shallot preparation on human umbilical vein endothelial cell (HUVEC) injury induced by oxidized low density lipoprotein (Ox-LDL) in vitro.

Methods: Ox-LDL was prepared and identified, and HUVECs were cultured. After 2-hour intervention of different drugs and 24-hour following intervention of Ox-LDL, the number of HUVECs was observed by phase contrast optical microscope and the activity of the HUVECs was observed by methyl thiazolyl tetrazolium (MTT) technique.

[Immortalized human odontoblast-like cell line expressed dentin extracellular matrix in vitro].

Objective: To determine whether dentin matrix proteins were expressed by the human odontoblast-like cell line hTERT-hOd-1 in vitro.

Methods: Collagen type I, bone sialoprotein (BSP), dentin matrix protein 1 (DMP1) and the marker for odontoblast, dentin sialophosphoprotein (DSPP) and dentin sialoprotein (DSP) were detected in these cells by immunohistochemistry, RT-PCR and in situ hybridization. During being cultured in mineralizing medium for 5 weeks, the secretion of OC and activity of ALP were measured once a week.
