Production of mulberry wine using selenium-enriched Saccharomyces cerevisiae: implications from sensory analysis, phytochemical and antioxidant activities.

The present study aims to evaluate the quality of chemical, sensory properties and antioxidant potential of mulberry wine using selenium-enriched yeasts employing eight different methods (MW1-MW8). The selenium-enriched yeast significantly (p < 0.05) increased phytochemical profiles, flavor, quality and antioxidant capacity. The most effective method for raising the selenium level of mulberry wine was using L-seMC (MW5). Mulberry wine color was attributed to the anthocyanins and phytochemical composition with selenium content. DPPH and ABTS radical scavenging activity varied with change in treatment methods suggesting their impact on antioxidant activity. Total selenium content on L-SeMC supplementation proved a significant correlation between selenium content with total anthocyanin content, total polyphenol content and flavonoid content. Sensory analysis by electronic nose exhibited MW2 with high response value in the W2S sensor showing high alcohol concentration. GC-MS analysis showed the presence of 57 volatile aromatic compounds comprehended by esters and alcohol (isoamyl alcohol, 2-methylbutanol, 2,3-butanediol, and phenethyl alcohol). Principal component analysis affirms the response values for four categorical score values with reliability and consistency for all the parameters, significantly. Thus, the workflow demonstrates a simpler, cost-effective traditional methodology for rationalized outcomes.

Diagnosis of mucoepidermoid carcinoma of parotid gland by virtual touch tissue quantification / 中华超声影像学杂志

Objective To explore the value of virtual touch tissue quantification(VTQ) in diagnosis of mucoepidermoid carcinoma (MECa) of parotid gland.Methods The sonographic and VTQ findings of 36 patients with MECa of parotid gland proved by pathology were analyzed retrospectively.The patients were divided into 3 groups according to pathology.50 normal subjects were choesn as control group.Results There were significant differences of shear wave velocity (SWV) between MECa groups and control group as well as among MECa groups (all P ＜0.01).Conclusions VTQ provides quantitative information about tissue stiffness which is useful for the diagnosis of MECa of parotid gland.

Compare and analysis about hypertrophic cardiomyopathy and hypertensive left ventricular hypertrophy with strain rate imaging / 中华超声影像学杂志

Objective To analyze strain characteristics of hypertrophic cardiomyopathy(HCM) and explore the clinical value of strain rate imaging in differentiating HCM from hypertensive left ventricular hypertrophy(H-LVH). Methods Parameters of strain and strain rate were obtained and compared among 23 HCM patients, 30 patients with H-LVH and 20 healthy people(control group). Results In HCM group, systolic strain(?_ sys ),peak systolic strain rate(SR_ sys ), early diastolic strain rate(SR_ dia ) obtained from inter-ventricle septum(IVS) were smaller than that obtained from left ventricle posterior wall(LVPW), while SR_a increased in IVS. ?_ sys ,SR_ sys ,SR_ dia in both patients with HCM and H-LVH were smaller than that in control group, while atrial systolic strain rate(SR_a) increased in HCM group and H-LVH group. ?_ sys , SR_ sys , SR_ dia , SR_a obtained from IVS and ?_ sys , SR_ dia obtained from LVPW in HCM group showed statistic differences compared with H-LVH group. Conclusions Strain rate imaging could accurately detect the abnormal regional myocardial function of HCM and can be applied as a useful tool in discriminating HCM from H-LVH.
