Surface inducing high-temperature superconductivity in layered metal carborides LiBC and LiBC by metallizing σ electrons.

Metallizing σ electrons provides a promising route to design high-temperature superconducting materials, such as MgB and high-pressure hydrides. Here, we focus on two MgB-like layered carborides LiBC and LiBC; their bulk does not have superconductivity because the B-C σ states are far away from the Fermi level (), however, based on first-principles calculations, we found that when their bulk systems are cleaved into surfaces with B-C termination, high of ∼80 K could be observed in the exposed B-C layer on the surfaces. Detailed analysis reveals that surface symmetry reduction, due to lattice periodic breaking, not only introduces hole self-doping into surface B-C layers and shifts the σ-bonding states towards the - associated with emergent large electronic occupation, but also makes in-plane stretching modes on the surface layer experience significant softness.

Lipidomic landscape of lipokines in adipose tissue derived extracellular vesicles.

Adipose tissue-derived extracellular vesicles (EVs-AT) are recognized as critical mediators of metabolic alterations in obesity-related diseases. However, few studies have focused on the role of lipids within EVs-AT in the development of obesity-related diseases. In this study, we performed a targeted lipidomic analysis to compare the lipidome of EVs secreted by inguinal white adipose tissue (EVs-iWAT), epididymal white adipose tissue (EVs-eWAT), and interscapular brown adipose tissue (EVs-BAT) in lean and obese mice.

Exploring microproteins from various model organisms using the mip-mining database.

Microproteins, prevalent across all kingdoms of life, play a crucial role in cell physiology and human health. Although global gene transcription is widely explored and abundantly available, our understanding of microprotein functions using transcriptome data is still limited. To mitigate this problem, we present a database, Mip-mining ( https://weilab.

Acupuncture as a therapeutic intervention for post-COVID-19 vaccination urticaria: a systematic review and meta-analysis protocol.

Introduction: The COVID-19 pandemic persisted for over 3 years since its onset in December 2019, posing an ongoing global threat to human health. In the absence of specific antiviral medications for COVID-19, vaccination has emerged as a popular preventive measure adopted by the general public. However, an undesirable consequence of COVID-19 vaccination has been the frequent incidence of urticaria, a type of adverse skin manifestations.

Comparison of Tensile Properties and Knot Security of Surgical Sutures: An In Vitro Mechanical Study.

Purpose: Studies on the mechanical properties and knot security of smaller sutures used in oral and maxillofacial surgery are limited. The objective of this study is to measure the tensile properties and knot security depending on the suture materials, knotting techniques, and number of throws using 5-0 sized sutures.

Methods: Seven 5-0 sized sutures were measured in both straight-pull and knot-pull according to the procedures outlined by the United States Pharmacopeia.

Bone-Adipose Tissue Crosstalk: Role of Adipose Tissue Derived Extracellular Vesicles in Bone Diseases.

Bone is a metabolically active organ that undergoes constant remodeling throughout life. A failure of this process leads to pathological destructive bone diseases such as osteoporosis, rheumatoid arthritis, and osteoarthritis. Studies of the interplay between adipose tissue and bone system, have revealed that adipose tissue disorders (e.

[Exploration of yeast biodiversity and development of industrial applications].

Yeast are comprised of diverse single-cell fungal species including budding yeast Saccharomyces cerevisiae and various nonconventional yeasts. Budding yeast is well known as an important industrial microorganism, which has been widely applied in various fields, such as biopharmaceutical and health industry, food, light industry and biofuels production. In the recent years, various yeast strains from different ecological environments have been isolated and characterized.

Bioinformatics Analyses of Potential miRNA-mRNA Regulatory Axis in HBV-related Hepatocellular Carcinoma.

We aimed to explore the crucial miRNA-mRNA axis through bioinformatics analysis and provide evidences for the development of pathophysiological mechanisms and new therapies for HBV-related HCC. MiRNA (GSE76903) and mRNA (GSE77509) dataset were used to screen differentially expressed miRNAs (DE-miRNAs) and differentially expressed mRNAs (DE-mRNAs) using R software. Overlapping genes between DE-mRNAs and target genes of DE-miRNAs were identified as candidate genes.

Concentrated Growth Factor Enhanced Fat Graft Survival: A Comparative Study.

Background: Concentrated growth factors (CGFs) belong to a new generation biomaterials that concentrate large number of growth factors and CD34 stem cells in small volume of plasma.

Objective: The purpose of this study was to evaluate the impact of the new technique, CGF, on fat graft survival, which compared with platelet-rich plasma (PRP) and platelet-rich fibrin (PRF).

Materials And Methods: Nude mice received fat graft were divided into PRP group, PRF group, CGF group, and saline.

Comparison of the Microstructures and Properties of Different Microcannulas for Hyaluronic Acid Injection.

Background: Microcannulas are used for hyaluronic acid and other filler injections and reduce the side effects and complications. There are several microcannulas and the differences between microcannulas have not been carefully investigated. The purpose of this study was to compare the microstructures and properties of different microcannulas by several trials and provide guidance for clinical application.

Botulinum toxin A improves adipose tissue engraftment by promoting cell proliferation, adipogenesis and angiogenesis.

Adipose tissue engraftment has become a well-established therapy in plastic and reconstructive surgery used to restore age-related or injury-related soft tissue loss. However, the unpredictable absorption rates limit its further application. Some clinicians have noted that more optimal aesthetic results are achieved when botulinum toxin A (BoNTA) is applied prior to adipose tissue grafting.

Comparison of Intra-arterial and Subcutaneous Testicular Hyaluronidase Injection Treatments and the Vascular Complications of Hyaluronic Acid Filler.

Background: Hyaluronidase is a key preventative treatment against vascular complications of hyaluronic acid (HA) filler injection, but the degradation profile of HA to hyaluronidase is limited, and the comparison between intra-arterial and subcutaneous injections of hyaluronidase has not been studied.

Objective: To evaluate HA degradation to hyaluronidase and compare different treatments between intra-arterial and subcutaneous testicular hyaluronidase injections.

Materials And Methods: The authors observed HA degradation to hyaluronidase in vitro via microscopic examination and particle analysis.
