Substituent structure variances alter degradation pathways of sulfonamides in UV/PAA system: Insights from intermediates, ROS, and DFT calculations.

Sulfonamides (SAs) are one of the major emerging contaminants of concern, but comparative studies on the degradation of different types of SAs are still limited. This work comprehensively compared the degradation of sulfadiazine (SDZ), sulfamethoxazole (SMX) and sulfathiazole (STZ) under UV light in peracetic acid (PAA) from both experimental and theoretical aspects, as they represent two structural classes based on substituent differences. The two SAs with five-membered heterocyclic substituents (SMX, STZ) generally decomposed at faster rates, with SMX degrading up to 10 times faster than SDZ (pH = 3; PAA dosage = 80 mg/L).

Intra-articular adductor canal block has equivalent analgesic effect to traditional ultrasound-guided adductor canal block after total knee arthroplasty: a prospective randomized controlled trial.

Introduction: An adductor canal block (ACB) is widely accepted as a regional nerve block for pain management following total knee arthroplasty (TKA). However, no consensus exists concerning whether the analgesic effect is greater when joint surgeons perform intra-articular ACBs (IA-ACBs) or when anesthesiologists perform ultrasound-guided ACBs (UG-ACBs). We hypothesized that intra-articular ACBs (IA-ACBs) performed by joint surgeons and UG-ACBs performed by anesthesiologists based on peri-articular injections (PAI) would yield equivalent analgesic effects.

Systemic Treatment Followed by Radical Resection Combined with Intestinal Autotransplantation (RRCIA) for Locally Advanced Pancreatic Cancer: A Retrospectively Observational and Prospectively Validated Study.

Objective: The present study aimed to assess the efficacy of this approach and establish the criteria that identify LAPC patients who may achieve survival benefits from RRCIA.

Summary Background Data: Surgical resection for locally advanced pancreatic cancer (LAPC) remains challenging and associated with high morbidity and mortality, especially for surgery with major arterial reconstruction. We previously showed the feasibility and safety of Radical Resection Combined with Intestinal Autotransplantation (RRCIA) after systemic treatment.

Nanoparticle adhesion at liquid interfaces.

Nanoparticle adhesion at liquid interfaces plays an important role in drug delivery, dust removal, the adsorption of aerosols, and controlled self-assembly. However, quantitative measurements of capillary interactions at the nanoscale are challenging, with most existing results at the micrometre to millimetre scale. Here, we combine atomic force microscopy (AFM) and computational simulations to investigate the adhesion and removal of nanoparticles from liquid interfaces as a function of the particles' geometry and wettability.

Understanding collaborative consumption in the technology-driven sharing economy: A cost-benefit analysis perspective.

Driven by the extensive implementation of information communication technology, collaborative consumption has become more popular. Historically, people have always thought that the best way to get something is to obtain the ownership of it. However, collaborative consumption has recently seen a meteoric rise in popularity due to that obtaining the right to use rather than own.

Analysis of Umbilical Artery Hemodynamics in Development of Intrauterine Growth Restriction Using Computational Fluid Dynamics with Doppler Ultrasound.

Intrauterine growth restriction (IUGR), the failure of the fetus to achieve his/her growth potential, is a common and complex problem in pregnancy. Clinically, IUGR is usually monitored using Doppler ultrasound of the umbilical artery (UA). The Doppler waveform is generally divided into three typical patterns in IUGR development, from normal blood flow (Normal), to the loss of end diastolic blood flow (LDBF), and even to the reversal of end diastolic blood flow (RDBF).

Cardiac-specific Suv39h1 knockout ameliorates high-fat diet induced diabetic cardiomyopathy via regulating Hmox1 transcription.

Aim: Diabetic Cardiomyopathy (DCM), a common complication of Type 2 Diabetic Mellitus (T2DM), has been emerging as one of the leading causes of mortality in T2DM patients. During the past decade, although, clinical studies concerning DCM are increasing at an exponential rate, mechanisms underlying this disease still can't be clearly defined. Here, we aim to recognize the function of Suv39h1 in DCM and to explore underlying mechanisms during this disease, providing new insights into DCM and novel guide for clinical therapy development.
