Xylose recovery and bioethanol production from sugarcane bagasse pretreated by mild two-stage ultrasonic assisted dilute acid.

Pretreatment can improve biomass biodegradability. Here, a novel sugarcane bagasse (SCB) pretreatment process based on two-stage ultrasonic assisted dilute HSO (TUDA) under mild conditions was reported. After optimization, the pretreatment was shown to significantly degrade hemicellulose (92.

[Enhancement Effects and Mechanisms of Microscale Zero Valent Iron on the Performance of Anaerobic Co-digestion of Waste Activated Sludge and Food Waste].

Focusing on low biogas yields in the anaerobic co-digestion of waste activated sludge and food waste, the enhancing effects and mechanisms of microscale zero valent iron (mZVI) on anaerobic co-digestion was investigated. The results indicated that the addition of mZVI enhanced the methanogenesis stage of co-digestion but had no significant effect on the solubilization, hydrolysis, and acidification stages. With a dosage of 10 g·L mZVI, the cumulative methane yield (based on VS) within 15 days reached 238.

Serum Uric Acid as an Independent Risk Factor for the Presence and Severity of Early-Onset Coronary Artery Disease: A Case-Control Study.

Serum uric acid (UA) is the final product of purine metabolism in humans. The present study is aimed at identifying the potential association between serum UA and early-onset coronary artery disease (EOCAD). The study population consisted of 1093 EOCAD patients aged ≤50 years, and 1117 age- and sex-matched apparently healthy people served as controls.

[Effect of extract of Ginkgo biloba on doxorubicin-associated cardiotoxicity in patients with breast cancer].

Objective: To study the effect of extract of Ginkgo biloba (Egb761) on doxorubicin-associated cardiotoxicity in patients with breast cancer (BC).

Methods: Sixty BC patients in stage IV were randomly assigned to two groups, the control group was treated with chemotherapy, using 4 cycles of PA protocol alone and the treated group with the same chemotherapy and Egb761. Changes in electrocardiogram (ECG), myocardial enzyme spectrum (MES) and ultrasono-cardiogram (USCG) before and after treatment were observed.
