Realizing Highly Stable Quasi-2D Blue Perovskite Light-Emitting Diodes Using Energy Cascades Generated by Biomolecule-Derived Plasmonic Nanostructures.

Blue perovskite light-emitting diodes (LEDs) lag behind green and red LEDs, which have made considerable strides in efficiency and stability. The main disadvantage is its unmodulated phase domains and low energy transfer efficiency, which impede the efficiency, optical purity, and operational stability of the devices. Herein, we show that using biomolecule-derived plasmonic nanostructures can significantly promote defect passivation, van der Waals gap reduction, and cascade energy transfer through synergistic small-molecule interactions and localized surface plasmonic contributions, thereby improving the electroluminescence (EL) properties and operational stability.

Framing emission gain layers for perovskite light-emitting diodes using polycaprolactone-silver nanoparticles featuring Förster resonance energy transfer and Purcell effects.

In this study, a new emission gain layer for perovskite light-emitting diodes (PeLEDs) is presented to improve their performance. The emission gain layer consisting of absorption-stable silver nanoparticles is prepared using the post-addition method of the polycaprolactone capping agent (PCL@AgNPs-P). This layer (PCL@AgNPs-P) effectively improves the Förster resonance energy transfer (FRET) between the low- (minor) and high- (major) phases in a quasi2D perovskite system, thereby increasing the major emission intensity and efficiency.

Rh(II)-Catalyzed Chemoselective Oxy-alkynylation of Acceptor-Acceptor Carbenes: Synthesis of C2-Quaternary Alkyne-Substituted 3(2)-Furanones.

A Rh(II)-catalyzed oxy-alkynylation of acceptor-acceptor carbenes using EBX reagents was successfully developed. The key alkyne-transfer step is likely to occur through a tandem process involving a β-addition, an α-elimination, and a 1,2-shift, which was supported by the formation of alkylidene carbene. Various diverse C2-quaternary alkyne-substituted benzofuran-3-ones and 2,2,4,5-tetrasubstituted 3(2)-furanones can be synthesized smoothly, depending on the choice of diazo compounds and the base additives.

Nanofiber-Based Odor-Free Medical Mask Fabrication Using Polyvinyl Butyral and Eucalyptus Anti Odor Agent.

Following the 2020 COVID-19 worldwide outbreak, many countries adopted sanitary and safety measures to safeguard public health such as wearing medical face mask. While face masks became a necessity for people, disadvantages impede their long period wearing such as uncomfortable breathability and odor. The intermediate layer of the medical face mask is composed of porous non-woven fabric to block external particles while maintaining breathability.

Electroacupuncture Reduces Anxiety Associated With Inflammatory Bowel Disease By Acting on Cannabinoid CB1 Receptors in the Ventral Hippocampus in Mice.

The therapeutic effects of electroacupuncture (EA) on the comorbidity of visceral pain and anxiety in patients with inflammatory bowel disease (IBD) is well known. It has been known that the ventral hippocampus (vHPC) and the cannabinoid type 1 receptors (CB1R) are involved in regulating anxiety and pain. Therefore, in this study, we determined whether EA reduces visceral pain and IBD-induced anxiety CB1R in the vHPC.

Electroacupuncture Reduces Visceral Pain Via Cannabinoid CB2 Receptors in a Mouse Model of Inflammatory Bowel Disease.

Inflammatory bowel disease (IBD) results in chronic abdominal pain in patients due to the presence of inflammatory responses in the colon. Electroacupuncture (EA) is effective in alleviating visceral pain and colonic inflammation associated with IBD. Cannabinoid CB2 receptor agonists also reduce colonic inflammation in a mouse model of IBD.

Rare cytochalasans isolated from the mangrove endophytic fungus Xylaria arbuscula.

Four new cytochalasans, arbuschalasins A-D (1-4), along with thirteen known analogues (5-17), were isolated from the solid rice medium of endophytic fungus Xylaria arbuscula. Arbuschalasins A-B feature a rare 5/6/6/6 fused ring system while arbuschalasin D was characterized as the first example of natural cytochalasans that possesses a 5/5/11 fused scaffold. The structures of 1-4 were assigned by spectroscopic data, with their absolute structures being determined by electronic circular dichroism (ECD) calculations.

Sishen Pill Maintained Colonic Mucosal Barrier Integrity to Treat Ulcerative Colitis via Rho/ROCK Signaling Pathway.

Sishen Pill (SSP) is a classical prescription of traditional Chinese medicine and often used to treat gastrointestinal diseases, including ulcerative colitis (UC). However, its mechanism is still unclear. We aimed to determine the mechanism of SSP in the treatment of UC by investigating if it maintains the integrity of the intestinal mucosal barrier via the Rho A/Rho kinase (ROCK) signaling pathway.

How to Improve the Effect of Microvascular Decompression for Hemifacial Spasm: A Retrospective Study of 32 Cases with Unsuccessful First Time MVD.

Background:  Microvascular decompression (MVD) has become accepted as an effective therapeutic option for hemifacial spasm (HFS); however, the curative rate of MVD for HFS varies widely (50-98%) in different medical centers. This study could contribute to the improvement of the MVD procedure.

Methods:  We retrospectively analyzed 32 patients in whom initial MVD failed in other hospitals and who underwent a second MVD at our center.

Research on clinical characteristics and prognostic analysis of heparin-induced thrombocytopenia after surgery for acute type a aortic dissection.

Purpose: The present study aimed to explore the clinical characteristics of heparin-induced thrombocytopenia (HIT) after surgery for acute type A aortic dissection and perform a relevant prognostic analysis.

Methods: After continuous observation and analysis of 204 patients who underwent acute type A aortic dissection, we found that blood platelets decreased significantly after surgery and that these patients can be suspected to suffer HIT based on relevant 4Ts scores. For these suspected HIT patients, a latex particle-enhanced immunoturbidimetric assay was conducted to detect heparin-induced antibodies.

Combined treatment with valproic acid and estrogen has neuroprotective effects in ovariectomized mice with Alzheimer's disease.

Postmenopausal women with Alzheimer's disease (AD) exhibit dramatically reduced sensitivity to estrogen replacement therapy, which is though to be related to an estrogen receptor (ER)α/ERβ ratio imbalance arising from a significantly decreased level of ERs of the brain. The aim of our study was to investigate whether valproic acid (VPA) can enhance the beneficial effects of estrogen on cognitive function through restoration of ERα and ERβ expression in the brain. We removed the ovaries of female APP/PS1 mice to simulate the low estrogen levels present in postmenopausal women and then administered VPA (30 mg/kg, intraperitoneal injection, once daily), 17β-estradiol (E2) (2.

Monocular posterior scleritis presenting as acute conjunctivitis: A case report.

Background: Posterior scleritis is a rare inflammatory ocular disease, characterized by severe and painful inflammation of the sclera. It is often misdiagnosed or underdiagnosed, due to its general and varying clinical presentation profile, which primarily involves pain and visual impairment but which can include eyelid edema, choroidal folds, serous retinal detachment, disc edema, hard exudates in fovea and subretinal mass. We report here a case of posterior scleritis, with symptoms of eye pain and red eye, initially misdiagnosed as acute conjunctivitis.
