[Effects of Fly Ash on the Efficiency and Bacterial Community Structure of Urban Multi-source Organic Solid Waste].

To achieve efficient resource utilization of fly ash and multi-source organic waste, a composting experiment was carried out to investigate the effects of fly ash on co-aerobic composting using kitchens, chicken manure, and sawdust (15:5:2). The effects of different application doses (5 % and 10 %, calculated in total wet weight of organic solid waste) of fly ash on physical and chemical properties, nutrient elements, and bacterial community structure during co-composting were evaluated. The results showed that the addition dose of 5 % and 10 % fly ash significantly increased the highest temperature (56.

Analysis of daily goal sheets on physician-nurse collaboration attitude.

Background: Optimal communication and collaboration between inter-disciplinary health care providers is critical to ensuring high quality patient care. We aimed to quantify the impact on physician-nurse collaboration (PNC) of implementing daily goal sheets (DGSs) in emergency settings.

Methods: The usage of a DGS was administered in morning rounds in an emergency intensive care unit (ICU) for four consecutive months.

Identification of PRDX6 as a regulator of ferroptosis.

Ferroptosis is a newly characterized iron-dependent form of nonapoptotic regulated cell death triggered by lipid reactive oxygen species (LOOH). The dysregulation of ferroptosis is highly related to cancer, and the induction of ferroptosis is also proposed as a potential strategy for cancer therapy. Although several key regulators have been identified that are involved in ferroptosis, the molecular mechanism underlying this process remains largely unknown.

Sleep Deprivation and Late Bedtime Impair Sperm Health Through Increasing Antisperm Antibody Production: A Prospective Study of 981 Healthy Men.

BACKGROUND The aim of this study was to investigate the effects of sleep duration and bedtime on sperm health, and the possible mechanism involved. MATERIAL AND METHODS We randomly divided 981 healthy Chinese men into groups according to research-set bedtimes (A=8-10 PM, B=after 10 PM, and C=after midnight) and sleep durations: group 1=<6.0 h (short), group 2=7.

Comparison of core decompression and conservative treatment for avascular necrosis of femoral head at early stage: a meta-analysis.

The purpose of the current meta-analysis was to compare the efficacy of core decompression (CD) and conservative treatment (CT) for saving femoral heads in patients with avascular necrosis of femoral head (ANFH). Four RCTs and two CCTs involving 323 hips with 24- to 48-months follow-up were included in this review. Our results suggested CD had a trend of favorable results in contrast to other CT (OR 3.

Efficacy of alendronate for preventing collapse of femoral head in adult patients with nontraumatic osteonecrosis.

The purpose of the current review was to determine the efficacy of alendronate for preventing collapse of femoral head in adult patients with nontraumatic avascular osteonecrosis of femoral head (ANFH). Five randomized controlled trials (RCTs) involving 305 hips were included in this review, of which 3 studies investigated alendronate versus control/placebo and the other 2 studies compared the combination of alendronate and extracorporeal shockwave therapy (ESWT) with ESWT alone. Our results suggested that even the patients with extensive necrosis encountered much less collapse in the alendronate group than control group.

Use of a tourniquet in total knee arthroplasty: a systematic review and meta-analysis of randomized controlled trials.

Background: A tourniquet is commonly used in total knee arthroplasty (TKA). However, the effectiveness and safety of tourniquets are debated. We performed this study to investigate whether patients benefit from the use of tourniquets in TKA.

The impact of umbilical blood flow regulation on fetal development differs in diabetic and non-diabetic pregnancy.

Background/aims: Diabetes is well-known to influence endothelial function. Endothelial function and blood flow regulation might be different in diabetic and non-diabetic pregnancy. However, the impact of umbilical blood flow regulation in gestational diabetes on fetal development is unknown so far.

[Study on the interaction of quercetin with beta-glucosidase by fluorescence spectroscopy and molecular docking].

Combined with molecular docking model, a fluorescence method was applied to investigate the interaction between quercetin and beta-glucosidase and the acting mechanism. The interaction between beta-glucosidase and quercetin, as well as the enzyme inhibitor 4-nitrophenyl-beta-D-thioglucoside, was studied by the AutoDock4.2 molecular docking model, respectively.

[The interaction between genistein and beta-glucosidase].

The interaction between genistein and beta-glucosidase was studied using fluorescence quenching method and synchronous fluorimetry. The binding reaction was simultaneously studied by the AutoDock 4.2 molecular docking model.

[Isolation and degradation characteristics of acetochlor-degrading strain A-3].

The strain A-3 which could use acetochlor as the sole nitrogen source was isolated from soils contaminated with acetochlor and the sludge of pesticide factory by enrichment culture. The strain was identified as Ensifer adhaerens according to the results of morphology, physiology,and the phylogenetical analyses of 16S rRNA sequence. It was observed that the degradation rate of acetochlor by strain A-3 was 33.
