Accuracy of breast ultrasound image analysis software in feature analysis: a comparative study with sonographers.

Breast ultrasound is recommended for early breast cancer detection in China, but the rapid increase in imaging data burdens sonographers. This study evaluated the agreement between artificial intelligence (AI) software and sonographers in analyzing breast nodule features. Breast ultrasound images from two hospitals in Shanghai were analyzed by both the software and the sonographers for features including echotexture, echo pattern, orientation, shape, margin, calcification, and posterior echo attenuation.

Modification of polyvinylidene fluoride membrane with ciprofloxacin to improve the bacteriostatic performance.

The common polyvinylidene fluoride (PVDF) membrane itself is susceptible to membrane fouling, especially biofouling, which is a serious threat. In this study, PVDF membrane was modified with ciprofloxacin (CIP) through co-blending to investigate the filtration properties, bacterial inhibition and fouling resistance. Modified membranes were prepared by adding 0.

Association between Dietary Patterns and All-Cause Mortality in the Chinese Old: Analysis of the Chinese Longitudinal Healthy Longevity Survey Cohort.

Diet is one of the most important ways to intervene and promote the health of older adults and reduce all-cause mortality. This study aimed to investigate the association between dietary patterns and all-cause mortality in the Chinese old. This study involved 11,958 subjects aged 65-116 years in the Chinese Longitudinal Healthy Longevity Survey (CLHLS) from 2008 to 2018.

Evaluation of the psychometrics of the Social Impact Scale and its association with depression among asymptomatic COVID-19 carriers.

Background: COVID-19 carriers experience psychological stresses and mental health issues such as varying degrees of stigma. The Social Impact Scale (SIS) can be used to measure the stigmatisation of COVID-19 carriers who experience such problems.

Aims: To evaluate the reliability and validity of the Chinese version of the SIS, and the association between stigma and depression among asymptomatic COVID-19 carriers in Shanghai, China.

Degradation of sulfamethoxazole and antibiotic resistance genes from surface water in the photocatalyst-loading bionic ecosystems.

The behavior and removal of sulfamethoxazole (SMX) and 3 typical corresponding antibiotic resistance genes (ARGs) including sul1, sul2, sul3, and 16S rDNA in surface water were investigated in the photocatalyst-loading bionic ecosystems (PCBEs). Synthesized composite photocatalyst g-CN/TiO showing higher catalytic activity than Fe/g-CN/TiO was selected in the PCBEs. Five PCBEs, i.

Cost comparison of advanced oxidation processes for wastewater treatment using accumulated oxygen-equivalent criteria.

Advanced oxidation processes (AOPs) have received a lot of attention over the years as advanced physico-chemical polishing wastewater treatments to remove biorefractory pollutants. Additionally, many studies report their excellent degradation and mineralization performance as stand-alone technologies too, demonstrating the versatility of these processes; however, there is a lack of suitable methods to compare the performance (in terms of removal efficiency and operating costs) of different AOPs in the same conditions. In this context, the goal of this paper is to propose a systematic investigation by introducing a novel criterion, namely the accumulated oxygen-equivalent chemical-oxidation dose (AOCD), to systematically compare the diverse AOPs available: ozonation, HO photolysis, Fenton, photo-Fenton, electro-Fenton and photoelectro-Fenton (paired with anodic oxidation, for the latter two).

Polyvinyl alcohol/chitosan composite hydrogels with sustained release of traditional Tibetan medicine for promoting chronic diabetic wound healing.

The Tibetan eighteen flavor dangshen pills (TEP) are composed of 18 traditional Tibetan medicines, which are commonly used in the treatment of skin diseases in the Tibetan medical system. They have anti-inflammatory and analgesic effects, and healing properties. However, TEP contain large doses and have strong side effects and low bioavailability.

Electro-Fenton beyond the Degradation of Organics: Treatment of Thiosalts in Contaminated Mine Water.

Electro-Fenton (EF) is an emerging technology with well-known outstanding oxidation power; yet, its application to the treatment of inorganic contaminants has been largely disregarded. Thiosalts are contaminants of emerging concern in mine water, responsible for delayed acidity in natural waterways. In this study, EF was used to treat thiosalts in synthetic and real mine water.

Cell-Membrane-Targeted Drug Delivery System Based on Choline-Phosphate-Functionalized β-Cyclodextrin.

In this study, a novel cyclodextrin derivative, i.e., zwitterionic choline phosphate (CP)-functionalized β-cyclodextrin (CP-β-CD) is successfully synthesized by click chemistry reaction.

Poly[2-(methacryloyloxy)ethyl choline phosphate] functionalized polylactic acid film with improved degradation resistance both in vitro and in vivo.

In this study, the surface-initiated atom transfer radical polymerization (SI-ATRP) of 2-(methacryloyloxy) ethyl choline phosphate (MCP) was successfully carried out via the ATRP initiator immobilized on the surfaces of polylactic acid (PLA) films. Different amounts of PMCP polymer brushes were constructed on the PLA surface to investigate the effects of the biological and degradation properties before and after modification. The results showed that the hydrophilicity of the surface of PLA were improved by MCP modification.

Advanced electrocatalytic pre-treatment to improve the biodegradability of real wastewater from the electronics industry - A detailed investigation study.

For the first time, real effluents from the micro-electronics industry were treated by paired advanced electrocatalysis, combining electro-Fenton (EF) with anodic oxidation (AO). A detailed characterization of the effluents was performed, showing that isopropanol (IPA) and acetone were the main constituents of the wastewater. Both compounds were completely degraded during the first 120 min of treatment.
