Scalable, Waterproof, Breathable, and Flexible Polyolefin-Elastomer/Polyethylene Glycol@Zinc Oxide Microfibrous Fabrics for Daytime Radiative Cooling Clothing.

In the face of escalating global temperatures, the demand for innovative passive cooling technologies that are both low-cost and environmentally sustainable is more critical than ever. However, traditional cooling fabrics face challenges in achieving wearing comfort while maintaining breathability and durability. Herein, a novel fluffy microfibrous fabric utilizing polyolefin-elastomer and polypropylene with embedded zinc oxide nanoparticles is fabricated through melt-blown technology.

Efficacy of surgical resection and ultra-reduced tension suture combined with superficial radiation in keloid treatment.

Background: There are many available treatment options for keloid; however, single treatments are usually less effective. Therefore, more scientifically rational and effective combined treatment methods should be sought to solve the pain associated with keloids.

Aim: To explore the efficacy and safety of surgical resection and ultra-reduced tension suture combined with superficial radiation as keloid treatment.

Magnetic metal-organic framework MIL-100 (Fe)/polyethyleneimine composite as an adsorbent for the magnetic solid-phase extraction of fungicides and their determination using HPLC-UV.

FeO@MIL-100 (Fe)/PEI are used for the first time as an adsorbent material for the extraction of pesticide residues (epoxiconazole, flusilazole, tebuconazole, and triadimefon) from food matrices. The adsorbent proposed (FeO@MIL-100(Fe)/PEI) was characterized by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), transmission electron microscopy (TEM), field emission scanning electron microscopy (FE-SEM), thermogravimetric (TG) analysis, and vibrating sample magnetometer (VSM) techniques to evaluate the properties of the sorbent. Then, the FeO@MIL-100 (Fe)/PEI was employed for the quantification of the four triazole fungicides in fruits and vegetables (apple, orange, tomato, cabbage, and cucumber) using HPLC-UV for separation and detection.

Magnetic Polydopamine Modified with Choline-Based Deep Eutectic Solvent for the Magnetic Solid-Phase Extraction of Sulfonylurea Herbicides in Water Samples.

A novel magnetic solid-phase extraction technique coupled to ultraperformance liquid chromatography has been developed for separation and preconcentration of four sulfonylurea herbicides (sulfosulfuron, bensulfuron-methyl, pyrazosulfuron-ethyl and halosulfuro-methyl) in aqueous samples. The key point of this method was the application of a novel magnetic nanomaterial that composed of a low eutectic solvent as a shell coated on the magnetic core modified by polydopamine. The extensive active sites outside the low eutectic solvent can effectively adsorb the target herbicide in the extraction process.

Physical Organohydrogels With Extreme Strength and Temperature Tolerance.

Tough gel with extreme temperature tolerance is a class of soft materials having potential applications in the specific fields that require excellent integrated properties under subzero temperature. Herein, physically crosslinked Europium (Eu)-alginate/polyvinyl alcohol (PVA) organohydrogels that do not freeze at far below 0°C, while retention of high stress and stretchability is demonstrated. These organohydrogels are synthesized through displacement of water swollen in polymer networks of hydrogel to cryoprotectants (e.

TBAB-Catalyzed 1,6-Conjugate Sulfonylation of para-Quinone Methides: A Highly Efficient Approach to Unsymmetrical gem-Diarylmethyl Sulfones in Water.

A highly efficient sulfonylation of -quinone methides with sulfonyl hydrazines in water has been developed on the basis of the mode involving a tetrabutyl ammonium bromide (TBAB)-promoted sulfa-1,6-conjugated addition pathway. This reaction provides a green and sustainable method to synthesize various unsymmetrical diarylmethyl sulfones, showing good functional group tolerance, scalability, and regioselectivity. Further transformation of the resulting diarylmethyl sulfones provides an efficient route to some functionalized molecules.

A highly diastereoselective [5+1] annulation to 2,2,3-trisubstituted tetrahydroquinoxalines via intramolecular Mannich-type trapping of ammonium ylides.

A novel tandem intermolecular ammonium ylide formation/intramolecular Mannich-type [5+1] cyclization reaction of aryl diazoacetates and ortho-aminophenyl imine derivatives was developed. The reaction provides an efficient methodology for direct synthesis of diverse trisubstituted tetrahydroquinoxalines bearing a quaternary stereogenic carbon center in moderate to good yields with excellent diastereoselectivity. This process features high efficiency, mild reaction conditions, and high stereoselectivity.

bFGF binding cardiac extracellular matrix promotes the repair potential of bone marrow mesenchymal stem cells in a rabbit model for acute myocardial infarction.

To assess the effect of basic fibroblast growth factor-binding extracellular matrix (bFGF-ECM) combined with bone marrow mesenchymal stem cells (BMSCs) transplantation on acute myocardial infarction (AMI) and explore the underlying mechenisms. Rabbit hearts were processed by decellularization with sodium dodecyl sulfate (SDS) perfusion, heparin immobilization, bFGF-binding and homogenization, for preparation of bFGF-binding cardiac ECM suspension (bFGF-ECM). Thereafter, the characteristics of bFGF release were analyzed in vitro.

HGF and IGF-1 promote protective effects of allogeneic BMSC transplantation in rabbit model of acute myocardial infarction.

Objectives: To explore effects of hepatocyte growth factor (HGF) combined with insulin-like growth factor 1 (IGF-1) on transplanted bone marrow mesenchymal stem cells (BMSCs), for treatment of acute myocardial ischaemia.

Materials And Methods: After ligation of the left anterior descending artery, rabbits were divided into a Control group, a Factors group (HGF+IGF-1), a BMSC group and a Factors+BMSCs group. Allogenous BMSCs (1 × 10(7)) and/or control-released microspheres of 2 μg HGF+2 μg IGF-1 were intramyocardially injected into infarcted regions.

Delayed enrichment for c-kit and inducing cardiac differentiation attenuated protective effects of BMSCs' transplantation in pig model of acute myocardial ischemia.

Objective: To investigate the effects of immature cardiomyocytes differentiated from c-kit(+) bone marrow mesenchymal stem cells (BMSCs) against acute myocardial infarction (AMI).

Methods: Miniswine passage 8 BMSCs were enriched for c-kit and induced by 5 μM 5-azacytidine (AZA) for 14 days, and a second enrichment for the dihydropyridine receptor subunit α2δ1 was performed (enriched BMSCs). Thereafter, enriched BMSCs were analyzed by determining cardiac differentiation, secretion function, and the effects of these secreted factors on cardiac stem cells (CSCs).
