An Experimental Study on the Thermal Performance of a Heat Sink Filled with Porous Aluminum Skeleton/Paraffin Composite Phase Change Material.

Organic phase change material is an ideal solution to solve the heat dissipation problem of electronic devices. However, its low thermal conductivity limits its application. To solve this problem, a new porous aluminum skeleton/paraffin composite phase change material (AS-PCM) was prepared.

G protein-coupled receptor 1 participating in the mechanism of mediating gestational diabetes mellitus by phosphorylating the AKT pathway.

Gestational diabetes mellitus (GDM) is a metabolic disease that occurs during pregnancy. Herein, we investigate G protein-coupled receptor 1 (GPR1) in mediating GDM through the phosphorylation of serine/threonine kinase (AKT) pathway. Thirty pregnant SD rats were grouped into: normal pregnancy control group (NC), GDM model group, and GDM model + high-dose GPR1 antagonist treatment (GDM + Ari) group.

Thermal Performance of Heat Sink Filled with Double-Porosity Porous Aluminum Skeleton/Paraffin Phase Change Material.

Phase change materials (PCMs) are used to cool high-power-density electronic devices because of their high latent heat and chemical stability. However, their low thermal conductivity limits the application of PCMs. To solve this problem, a double-porosity porous aluminum skeleton/paraffin phase change materials (DPAS/PCM) was prepared via additive manufacturing and the water-bath method.

Examining the association of hysterectomy with and without oophorectomy on cardiovascular disease and all-cause, cardiovascular or cancer mortality: A systematic review and meta-analysis.

Background: The associations between hysterectomy and cardiovascular disease (CVD) and mortality remains unlcear and a meta-analysis with cohort studies is lacking.

Objectives: This study aimed to conduct a systematic review and meta-analysis of cohort studies to investigate the relationship between hysterectomy and CVD, coronary heart disease (CHD), stroke, heart failure, and all-cause, cardiovascular and cancer mortality. We further explored the effect of oophorectomy on the association between hysterectomy and these health outcomes.

Experimental and Numerical Investigations on Thermal-Hydraulic Performance of Three-Dimensional Overall Jagged Internal Finned Tubes.

To satisfy the demand for efficient heat transfer, a novel three-dimensional overall jagged internal finned tube (3D-OJIFT) was fabricated, using the rolling-ploughing/extruding method. The thermal performance of the 3D-OJIFT were studied and compared in experiments and three-dimensional numerical simulations. The RNG - turbulence model is well verified with the experimental results.

The role of pyroptosis-related lncRNA risk signature in ovarian cancer prognosis and immune system.

Ovarian cancer is a leading cause of death in females with gynecologic cancers. Pyroptosis is a relatively new discovered programmed cell death that is believed to be associated with inflammation. However, studies on pyroptosis-related lncRNAs in ovarian cancer are limited.

An integrative pan-cancer analysis illustrating the key role of LRP11 in cervical cancer.

Background: Low density lipoprotein receptor-related protein 11 (LRP11) was involved in the progression of several tumors. However, its role in cervical cancer still remains uncertain.

Methods: The original tumor data was downloaded from the Cancer Genome Atlas and genotype-tissue expression databases.

Association between hypoalbuminemia and complications after degenerative and deformity-correcting spinal surgeries: A systematic review and meta-analysis.

Objective: The current review was designed to explore if hypoalbuminemia is associated with increased complications in patients undergoing spinal degenerative and deformities surgeries.

Methods: The search for eligible studies was conducted on the databases of PubMed, Embase, Web of Science, and CENTRAL up to 20th June 2022. Complication rates were pooled to obtain odds ratio (OR) and 95% confidence intervals.

Fabrication and Characteristics of Sintered Cutting Stainless Steel Fiber Felt with Internal Channels and an Al₂O₃ Coating.

A novel sintered cutting stainless steel fiber felt with internal channels (SCSSFFC) composed of a stainless-steel fiber skeleton, three-dimensional interconnected porous structure and multiple circular microchannels is developed. SCSSFFC has a jagged and rough surface morphology and possesses a high specific surface area, which is approximately 2.4 times larger than that of the sintered bundle-drawing stainless steel fiber felt with internal channels (SBDSSFFC) and is expected to enhance adhesive strength.

Cerium caused life span shortening and oxidative stress resistance in Drosophila melanogaster.

To investigate the effects of the rare earth element cerium (Ce) on the life span and biomarkers of oxidative stress in the fruit fly (Drosophila melanogaster). Fruit flies were fed on media with different dose of ceric sulfate (1, 4, 16, 64, 256, 1024mg/L, corresponding to cerium concentrations of 0.45, 1.

High-dose misoprostol as an alternative therapy after failed medical abortion.

Objective: The aim of this study was to determine the complete abortion rate for the vaginal administration of high-dose misoprostol after a failed medical abortion.

Materials And Methods: When their medical abortions failed after the conventional oral administration of mifepristone and misoprostol, participants then received 1,000 microg of misoprostol vaginally. The efficacy and side effects of this treatment were evaluated.

Visualization of the ribosomal DNA (45S rDNA) of Indica rice with FISH on some phases of cell cycle and extended DNA fibers.

The ribosomal DNA (45S rDNA) behaviors during the cell cycle were analyzed on interphase nuclei, prophases, metaphases, pachytene chromosomes and extended DNA fibers in rice (Oryza, sativa ssp. indica cv. Guangluai No.

[The progress and research of chromosome territories (CTs)].

Chromosomes are non-randomly distributed in interphase nucleus, and each chromosome occupies a distinct domain in the chromosome territories (CTs), the positioning and arrangement of CTs are well-organized, at the same time, the chromosome territories have definite dynamics characteristics, the strict positioning and spatial organization of chromosome territories are closely related with gene expression regulation. This paper reviewed progress in these respects.

On-demand therapy for Los Angeles grade A and B reflux esophagitis: esomeprazole versus omeprazole.

Background And Purpose: Reflux esophagitis of Los Angeles grade A or B is more common than grades C and D disease among Taiwanese. This study compared the efficacy of esomeprazole 40 mg and omeprazole 20 mg for starting on-demand therapy for grade A and B reflux esophagitis.

Methods: 100 patients with grade A and B reflux esophagitis were randomized to receive either esomeprazole 40 mg once daily (n = 50) or omeprazole 20 mg once daily (n = 50) for the first 4 weeks.
