Effects of Different Probiotics on the Volatile Components of Fermented Coffee Were Analyzed Based on Headspace-Gas Chromatography-Ion Mobility Spectrometry.

Headspace-gas chromatography-ion mobility spectrometry (HS-GC-IMS) was used to study the effects of four kinds of probiotics on the volatile components of fermented coffee. The fingerprints showed that 51 compounds were confirmed and quantified, including 13 esters, 11 aldehydes, 9 alcohols, 6 ketones, 3 furans, 5 terpenes (hydrocarbons), 2 organic acids, 1 pyrazine, and 1 sulfur-containing compound. After fermenting, the aroma of the green beans increases while that of the roasted beans decreases.

The protocol for the Prospective Urban Rural Epidemiology China Action on Spine and Hip status study.

The Prospective Urban Rural Epidemiology (PURE) China Action on Spine and Hip status (CASH) study focused on the prevalence of osteoporosis and spinal fracture in China. The aim of the PURE CASH study is to determine the prevalence of osteoporosis and spinal fracture, and explore the potential relationship between spinal fracture and bone mineral density (BMD). This study is a prospective large-scale population study with a community-based sampling and recruitment strategy.

[Diagnostic accuracy of noninvasive coronary artery angiography using 64 multi-slice computed tomography on coronary atherosclerosis].

Objective: To evaluate the diagnostic accuracy of 64 multislice computed tomography (MSCT) coronary angiography on the coronary atherosclerosis.

Methods: Sixty one (52 male, 9 female, averaged 58 +/- 11 yrs ) patients underwent conventional coronary angiography and 64-MSCT angiography for suspected coronary artery disease within 5 to 20 days. Coronary artery image quality was scored from 1 to 4 (image quality score, 1: poor; 2: good -; 3: good +, and 4: excellent) on RCA, LM, LAD and LCX, respectively.

[Multi-slice computed tomography of myocardial bridge and mural coronary artery and clinical significance thereof].

Objective: To investigate the diagnosis of myocardial bridge and mural coronary artery (MB-MCA) with multi-slice computed tomography (MSCT) and clinical significance thereof.

Methods: 900 patients suspected as with coronary artery disease (CHD) underwent 64-slice computed tomography performed by 3 radiologists independently. When consistency was obtained among the independent interpretations of the tomogram among them the diagnosis of MB-MCA could be confirmed.
