Safety and efficacy of low-powered holmium laser enucleation of the prostate in comparison with plasma kinetic resection of prostate.

To compare the efficacy and safety of low-power holmium laser enucleation of the prostate (LP-HoLEP) with plasma kinetic resection of prostate (PKRP). Sixty-three patients treated with transurethral LP-HoLEP (observation group) and 68 patients treated with transurethral PKRP (control group) at Beijing Hospital of Traditional Chinese Medicine from November 2019 to November 2022 were retrospectively compared with regard to operation duration, intra-operative blood loss, prostate resection ratio, postoperative bladder irrigation time, postoperative indwelling urinary catheter time, postoperative urinary incontinence incidence, International Prostate Symptom Scale (IPSS), maximum urine flow rate (Qmax), and residual urine volume (RUV). In both groups, postoperative IPSS, Qmax, and RUV were significantly improved compared to preoperative values (P < 0.

Chlorine and UV combination sequence: Effects on antibiotic resistance control and health risks of ARGs.

The effective control of antibiotic resistance in aquatic environments is urgent. The combined chlorine and UV processes (Cl-UV, UV/Cl, and UV-Cl) are considered potential control processes for controlling antibiotic resistance. This study compared the effectiveness of these three processes in real water bodies and the potential health risks associated with antibiotic resistance genes (ARGs) after treatments.

Performance and mechanism of glycerol-driven denitrifying phosphorus removal from low organic matter sewage.

The performance and mechanism of the glycerol-driven denitrifying phosphorus removal (DPR) process were investigated in low organic matter wastewater treatment using the modified anaerobic-anoxic-oxic (MAAO) system. The results revealed that denitrifying bacteria preferentially utilized glycerol, reducing nitrate interference on anaerobic phosphate release. Fermentation bacteria converted excess glycerol into available carbon sources, which were utilized by denitrifying phosphorus-accumulating organisms (DPAOs).

Enhancing low-temperature nitrification biofilter with Acinetobacter harbinensis HITLi7 for efficient ammonia nitrogen removal in engineering applications.

At 2 °C, with an empty bed contact time of 3 h, the LTNB achieved NH-N removal levels of 1.

Stimulation of an entorhinal-hippocampal extinction circuit facilitates fear extinction in a post-traumatic stress disorder model.

Effective psychotherapy of post-traumatic stress disorder (PTSD) remains challenging owing to the fragile nature of fear extinction, for which the ventral hippocampal CA1 (vCA1) region is considered as a central hub. However, neither the core pathway nor the cellular mechanisms involved in implementing extinction are known. Here, we unveil a direct pathway, where layer 2a fan cells in the lateral entorhinal cortex (LEC) target parvalbumin-expressing interneurons (PV-INs) in the vCA1 region to propel low-gamma-band synchronization of the LEC-vCA1 activity during extinction learning.

Therefore, existing studies improved AD efficiency by enhancing the electron transfer from microbes-to-pollutants or inter-microbes. This study synthesized a novel Fe, N co-doped biochar (Fe, N-BC), which could enhance both the microbes-to-pollutants and inter-microbes electron transfer in AD.

Sensory ASIC3 channel exacerbates psoriatic inflammation via a neurogenic pathway in female mice.

Psoriasis is an immune-mediated skin disease associated with neurogenic inflammation, but the underlying molecular mechanism remains unclear. We demonstrate here that acid-sensing ion channel 3 (ASIC3) exacerbates psoriatic inflammation through a sensory neurogenic pathway. Global or nociceptor-specific Asic3 knockout (KO) in female mice alleviates imiquimod-induced psoriatic acanthosis and type 17 inflammation to the same extent as nociceptor ablation.

An ultra-short-acting benzodiazepine in thalamic nucleus reuniens undermines fear extinction via intermediation of hippocamposeptal circuits.

Benzodiazepines, commonly used for anxiolytics, hinder conditioned fear extinction, and the underlying circuit mechanisms are unclear. Utilizing remimazolam, an ultra-short-acting benzodiazepine, here we reveal its impact on the thalamic nucleus reuniens (RE) and interconnected hippocamposeptal circuits during fear extinction. Systemic or RE-specific administration of remimazolam impedes fear extinction by reducing RE activation through A type GABA receptors.

Insights into effects of thermotolerant nitrifying and sulfur-oxidizing inoculants on nitrogen-sulfur co-metabolism in sewage sludge composting.

In this study, high temperature thermotolerant nitrifying bacteria (TNB) and high temperature thermotolerant sulfide oxidizing bacteria (TSOB) were obtained from compost samples and inoculated into sewage sludge (SS) compost. The effects of inoculation on physical and chemical parameters, ammonia and hydrogen sulfide release, nitrogen form and sulfur compound content change and physical-chemical properties during nitrogen and sulfur conversion were studied. The results showed that inoculation of TNB and TSOB increased the temperature, pH, OM degradation, C/N ratio and germination index (GI) of compost.
