Wood sawdust and maize straw were selected to co-compost sewage sludge to investigate the effects of organic bulking agents on the formation and molecular transformation of humic substances. The results showed that composting process increased humic acids (HA) while decreased fulvic acids (FA), and the wood sawdust and maize straw promoted the formation of HA by 25.6% and 16.1%, respectively. Results from fluorescence titration demonstrated that organic bulking agents also increased the binding ability of HA with the heavy metal ions, Cu(II) and Cd(II), but had little influence on that of FA. These findings indicate that organic materials especially wood sawdust may be used as bulking agents to reduce the mobility and bioavailability of toxic metals in solid waste composts.

Background And Objective: Stress urinary incontinence (SUI), defined as any involuntary leakage of urine associated with physical activity, remains underdiagnosed and undertreated. This review aims to provide an updated overview of the prevalence, diagnosis, and treatment of SUI in women, drawing upon recent evidence-based literature and clinical guidelines.
Methods: A systematic search of the MEDLINE database was conducted to identify only the most up-to-date and relevant studies published up to February 26, 2024, including the reference ESTER systematic review.

Low anterior resection syndrome (LARS) is a challenging complication following sphincter-preserving rectal surgery, characterized by bowel dysfunctions such as urgency, frequency, and incontinence. This case series investigates the potential role of lactose intolerance in exacerbating LARS symptoms. Three patients who developed LARS after rectal resections showed persistent symptoms despite conventional management with bulking agents, physiotherapy, and loperamide.

Household kitchen waste (HKW) is produced in large quantity and its management is difficult due to high moisture content and complex organic matter. Aerobic composting of HKW is an easy, efficient, cost-effective and eco-friendly method. This study is designed to achieve a zero-waste concept and to convert HKW.

Antibiotic resistance genes (ARGs) rebounding during composting cooling phase is a critical bottleneck in composting technology that increased ARGs dissemination and application risk of compost products. In this study, mature compost (MR) was used as a substitute for rice husk (RH) to mitigate the rebound of ARGs and mobile genetic elements (MGEs) during the cooling phase of sewage sludge composting, and the relationship among ARGs, MGEs, bacterial community and environmental factors was investigated to explore the key factor influencing ARGs rebound. The results showed that aadD, blaCTX-M02, ermF, ermB, tetX and vanHB significantly increased 4.

Polymerase chain reactions (PCR) are most reliable and precise means for nucleic acid analysis of biological samples. A cold-chain system with temperature at around -20°C is generally necessary for storage and transportation of PCR-related reagents. In order to facilitate ambient temperature storage and transportation, this study prepared Taq DNA polymerase and 5 × HS-Taq Mix (as low as 0.
