[Abundance and Fluorescent Components of Dissolved Organic Matter Affected by Land Use in a Drinking Water Source].

Regional concentrations, fluorescent components, and sources of dissolved organic matter (DOM) in a drinking water source in Chaobai River across seasons were investigated here using fluorescence excitation-emission matrices, parallel factor analysis, and fluorescence indexes. Five fluorescent-DOM components were identified, including two microbial humic-like components and one autochthonous tyrosine-like, one reduced quinone-like, and one terrestrial humic-like component. DOM was mainly derived from microorganisms.

Clinical characterization and prognostic implications of metabolic syndrome in patients undergoing peritoneal dialysis at a Chinese center.

Objective: Metabolic syndrome (MS) is a common clinical condition associated with cardiovascular disease in patients undergoing peritoneal dialysis (PD); however, its prognostic implication among patients receiving PD remains controversial.

Methods: In a prospective study from January 2013 and June 2016, we enrolled 190 patients undergoing PD and followed them for 46.4 ± 30.

Abnormal ankle-brachial index and risk of cardiovascular or all-cause mortality in patients with chronic kidney disease: a meta-analysis.

Prognostic role of ankle-brachial index (ABI) in patients with chronic kidney disease (CKD) is controversial. We aimed to evaluate whether abnormal ABI was an independent predictor of cardiovascular or all-cause mortality in CKD patients with or without hemodialysis by conducting a meta-analysis. We systematically searched Pubmed and Embase databases for prospective observational studies that investigated baseline abnormal ABI and subsequent cardiovascular or all-cause mortality risk in CKD patients with or without hemodialysis.

The Antibiosis Action and Rice-Induced Resistance, Mediated by a Lipopeptide from Bacillus amyloliquefaciens B014, in Controlling Rice Disease Caused by Xanthomonas oryzae pv. oryzae.

In the present study, a lipopeptide (named AXLP14) antagonistic to Xanthomonas oryzae pv. oryzae (Xoo) was obtained from the culture supernatant of Bacillus amyloliquefaciens B014. Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry analysis demonstrated that AXLP14 consisted of surfactin homologs.

Fibrin sheath formation and intimal thickening after catheter placement in dog model: role of hemodynamic wall shear stress.

Purpose: To investigate the role of wall shear stress in aspects of the formation of fibrin sheath and intimal thickening in a dog model.

Methods: Tunneled silicone 14.5-F catheters were inserted into the left internal jugular vein in eight dogs.

Nonsense mutations in the PAX3 gene cause Waardenburg syndrome type I in two Chinese patients.

Background: Waardenburg syndrome type I (WS1) is an autosomal dominant disorder characterized by sensorineural hearing loss, pigmental abnormalities of the eye, hair and skin, and dystopia canthorum. The gene mainly responsible for WS1 is PAX3 which is involved in melanocytic development and survival. Mutations of PAX3 have been reported in familiar or sporadic patients with WS1 in several populations of the world except Chinese.

[Large-scale screening of mtDNA A1555G mutation in China and its significance in prevention of aminoglycoside antibiotic induced deafness].

Objective: To explore the necessity of large-scale screening of mtDNA A1555G mutation in prevention of aminoglycoside antibiotic induced deafness (AAID) and to develop a feasible method to prevent AAID.

Methods: A total of 1836 patients with non-syndromic hearing impairment (NSHI), 1352 students of schools for deaf-mutes in 11 provinces and municipality in China, 413 out-patients, and 71 persons from the families with maternal relatives suffering from AAID, underwent questionnaire survey and/or PCR for A-to-G mutation at nucleotide 1555 of the mitochondrial genome.

Results: Sixty three patients with mtDNA A1555G mutation were found among the 1836 NSHI patients.
