Integration of Digestate-Derived Biochar into the Anaerobic Digestion Process through Circular Economic and Environmental Approaches-A Review.

The growing energy consumption and the need for a circular economy have driven considerable interest in the anaerobic digestion (AD) of organic waste, offering potential solutions through biogas and digestate production. AD processes not only have the capability to reduce greenhouse gas emissions but also contribute to the production of renewable methane. This comprehensive review aims to consolidate prior research on AD involving different feedstocks.

Improved organic matter biodegradation through pulsed H injections during in situ biomethanation.

During in situ biomethanation, microbial communities can convert complex Organic Matter (OM) and H into CH. OM biodegradation was compared between Anaerobic Digestion (AD) and in situ biomethanation, in semi-continuous processes, using two inocula from the digester (D) and the post-digester (PoD) of an AD plant. The impact of H on OM degradation was assessed using a fractionation method.

Archaeal community composition as key driver of H2 consumption rates at the start-up of the biomethanation process.

The performance of hydrogen consumption by various inocula derived from mesophilic anaerobic digestion plants was evaluated under ex situ biomethanation. A panel of 11 mesophilic inocula was operated at a concentration of 15 g.L at a temperature of 35 °C in batch system with two successive injections of H:CO (4:1 mol:mol).

Association Between Symptoms, Quality of Life, and Gastric Emptying in Dyspeptic Patients.

Background/aims: Association between symptoms, quality of life and gastric emptying in dyspepsia is inconsistent in the literature. The aim of our study is to investigate if gastric emptying is associated with specific symptoms and quality of life in dyspeptic patients.

Methods: We reviewed retrospectively gastric emptying measured by C-labelled octanoate breath testing for more than 6 hours in 198 consecutive patients with dyspepsia complaints.

miRNAs, a potential target in the treatment of Non-Small-Cell Lung Carcinomas.

Lung cancer is a serious public health problem and Non Small Cell Lung Carcinoma, NSCLC, is particularly resistant to current treatments. So it is important to find new strategies that are active against NSCLC. miRNA is implicated in cancer and may be implicated in NSCLC.
