Methods for improving the thermal performance of thermal bridges of lightweight steel-framed buildings.

The existence of a large number of thermal bridges in the Lightweight Steel-Framed (LSF) building leads to its energy loss. The reduction of the heat transfer of thermal bridges is crucial for increasing the thermal performance of the building envelope. In this study, the infrared technology was first used to measure the temperature of LSF buildings, and clear thermal bridge junctions were determined.

Investigating the effects and efficacy of self-compassion intervention on generalized anxiety disorders.

Background: Generalized anxiety disorder (GAD) is the least successfully treated anxiety disorder. This clinical trial investigated the effects and efficacy of a novel self-compassion intervention in GAD.

Methods: A total of 75 GAD patients were assigned to a self-compassion intervention group (n = 25), a mindfulness intervention group (n = 25), or a treat-as-usual group (n = 25).

A novel "turn-off" photoelectrochemical aptasensing platform for selective detection of tobramycin based on the TiC-MoS/BiOI heterojunction.

Tobramycin (TOB), as a widely used antibiotic, poses severe unpredictable risks to ecology and health. In this study, a novel photoelectrochemical (PEC) adapter sensor, based on its "turn-off" PEC mode, was constructed for TOB detection. This visible-light-driven photoelectrochemical (PEC) aptasensor was successfully developed for TOB detection using TiC-MoS/BiOI and TOB aptamer probes.

MWCNT modified Ni-Fe LDH/BiVO heterojunction: boosted visible-light-driven photoelectrochemical aptasensor for ofloxacin detection.

Sensitivity and selectivity, which can be identified by the photosensitivity of materials and the identification of elements, are two important factors for a photoelectrochemical aptasensor (PEC aptasensor). Herein, a patent PEC aptasensor for specifically detecting ofloxacin (OFL) was exploited, and a visible-light-active MWCNT/LDH/BiVO heterostructure was introduced as a photoactive material and identification elements, respectively. The combination of LDH with BiVO enhanced the photocurrent response, and MWCNT provided higher electron conductivity, which are advantageous for structuring PEC sensors.

Numerical study on the impact of wall structure on the thermal performance of double-channel porous solar wall.

With the improvement of people's living standards, they have higher requirements for indoor thermal comfort in the cold season. Solar wall utilizing solar energy for heating can reduce carbon emissions and achieve carbon neutrality. In the aspect of solar wall research, the influence of wall structure on the thermal performance of double-channel porous solar wall is limitedly investigated.

Experimental study of the catalytic effect of iron on low-rank coal gasification.

Acid-washing low-rank coal samples were loaded with different content of iron catalyst and then pyrolyzed. FT-IR, Raman spectra, and temperature-programmed experiments were used to investigate the influence of iron on the coal char. The FT-IR results revealed that iron catalyst rises the number of -OH, -CH, and -CH functional groups.

Printing 3D vagina tissue analogues with vagina decellularized extracellular matrix bioink.

A variety of factors can cause vaginal loss. The patients are suffering from great psychological and physical pain, and there is an urgent need for vagina reconstruction. 3D-bioprinting is expected to achieve vaginal morphological restoration and true functional reconstruction.

A stereological study of 3D printed tissues engineered from rat vaginas.

Background: This study aims to retrieve the stereological data from rat vaginas for 3D printing tissue-engineered vaginas.

Methods: In this study, five female Sprague-Dawley rats, aged 8-12 weeks, were used to obtaining the vagina tissues. Each vagina was divided into eight segments fixed in 4% paraformaldehyde and embedded in paraffin, whose two consecutive sections of each block were stained using hematoxylin and eosin (H&E) and anti-α-actin antibody with immunohistochemistry staining, respectively.

Exosomes Derived from Adipose Mesenchymal Stem Cells Restore Functional Endometrium in a Rat Model of Intrauterine Adhesions.

Intrauterine adhesion (IUA) caused by endometrial injury is one of the important causes of infertility in women of reproductive age and requires advanced treatment strategies. Increasing evidence suggests that the therapeutic effects of mesenchymal stem cells (MSC) mainly depend on their capacity to secrete paracrine factors and are mediated by MSC-derived exosomes. This study aimed to identify exosomes derived from adipose-derived mesenchymal stem cells (ADSC-exo) and explore the therapeutic potential in IUA rat models.

Controlled releasing of SDF-1α in chitosan-heparin hydrogel for endometrium injury healing in rat model.

Herein we report a facile approach for chitosan-heparin hydrogels with controlled release manner and their applications for intrauterine adhesion. The sol precursor was converted to gel at physiological temperature in 15 min. FTIR, SEM and swelling test were performed to characterize their compositions, morphologies and stability.

Density functional theory study the effects of oxygen-containing functional groups on oxygen molecules and oxygen atoms adsorbed on carbonaceous materials.

Density functional theory was used to study the effects of different types of oxygen-containing functional groups on the adsorption of oxygen molecules and single active oxygen atoms on carbonaceous materials. During gasification or combustion reactions of carbonaceous materials, oxygen-containing functional groups such as hydroxyl(-OH), carbonyl(-CO), quinone(-O), and carboxyl(-COOH) are often present on the edge of graphite and can affect graphite's chemical properties. When oxygen-containing functional groups appear on a graphite surface, the oxygen molecules are strongly adsorbed onto the surface to form a four-member ring structure.

A community-based controlled trial of a comprehensive psychological intervention for community residents with diabetes or hypertension.

Background: Depression and anxiety often occur in persons with chronic physical illnesses and typically magnify the impairment caused by these physical conditions, but little attention has been paid to this issue in low- and middle-income countries.

Aim: Evaluate the effectiveness of a community-based psychological intervention administered by non-specialized clinicians and volunteers for alleviating depressive and anxiety symptoms in individuals with chronic physical illnesses.

Methods: A total of 10, 164 community residents receiving treatment for diabetes or hypertension in Shanghai were arbitrarily assigned to a treatment-as-usual condition (n=2042) or an intervention condition (n=8122) that included community-wide psychological health promotion, peer support groups, and individual counseling sessions.

Mental health literacy among residents in Shanghai.

Background: The recent adoption of China's new national mental health law provides a good opportunity to obtain baseline information about community mental health literacy in the country.

Aim: Assess knowledge and attitudes about mental disorders among residents in Shanghai.

Methods: A total of 1953 residents aged 15 or above selected from all 19 districts in Shanghai completed two self-report questionnaires - the Mental Health Knowledge Questionnaire (MHKQ) and the Case Assessment Questionnaire (CAQ).
