Purpose: This meta-analysis aimed to evaluate the incidence and risk factors of intraoperative acquired pressure injuries (IAPIs) in open heart surgical patients, focusing exclusively on prospective studies to address gaps in the existing literature.

Methods: A systematic search was conducted across PubMed, Embase, and Web of Science up to January 2025. Data on incidence and risk factors were extracted, and statistical analyses were performed using random-effects models.

Dietary Sodium Butyrate Supplementation Enhances Silkworm Silk Yield by Simultaneously Promoting Larval Growth and Silk Gland Development.

Silk yield enhancement in sericulture has plateaued. Sodium butyrate (NaB) is known to improve production performance in livestock and poultry, yet its effects on silkworm silk yield remain uncharacterized. Here, we evaluated the impact of dietary NaB supplementation on silkworm growth, silk gland development, and cocoon output.

Objectives: This study aimed to investigate the relationship between sleep quality, anxiety, and depression among perioperative caregivers of children with tethered cord syndrome.

Methods: A cross-sectional study design was employed to recruit primary caregivers of children undergoing surgery for tethered cord syndrome from Fujian Children's Hospital between February 2022 and December 2023. Participants were required to complete some questionnaires, including the Pittsburgh Sleep Quality Index (PSQI), the Self-Rating Anxiety Scale, and the Self-Rating Depression Scale.

A Comprehensive Study on the Degradation Behavior and Mechanism of Expanded Thermoplastic Polyurethane.

Expanded thermoplastic polyurethane (ETPU) is used in a wide range of applications due to its excellent properties, but inevitably, aging deteriorates the material properties and shortens service lifetime. This study conducted aging experiments on ETPU to summarize the deterioration trend and provide reliable data. The ETPU underwent three distinct aging protocols: thermal aging for 28 days in a controlled 80 °C environment; xenon lamp aging under continuous UV irradiation (via xenon lamp) at 80 °C for 28 days; and weathering aging through 671 days of outdoor exposure to real-world weather conditions.

GABPα targeted by miR-378a-5p inhibits the growth and angiogenesis of colorectal carcinoma.

Considering the high degree of malignancy, recurrence rate and poor prognosis, exploring promising targets is an imperious strategy for colorectal carcinoma therapy. Recent studies have indicated that GABPα plays a role in cancer aggressiveness, but its exact function and regulatory mechanisms in colorectal cancer progression remain unclear. This study aims to explore the biological role of GABPα and its upstream regulator, miR-378a-5p, in modulating cancer progression.

Pancancer analysis of NDUFA4L2 with focused role in tumor progression and metastasis of colon adenocarcinoma.

Colon adenocarcinoma (COAD) is a prevalent gastrointestinal malignant disease with a high mortality rate, and identification of novel prognostic biomarkers and therapeutic targets is urgently needed. Although NDUFA4L2 has high expressions in various tumors and affects tumor progression, its role in COAD remains unclear. The role of NDUFA4L2 in COAD was analyzed utilizing datasets available from public databases including The Cancer Genome Atlas, The Genotype-Tissue Expression (GTEx), Gene Expression Omnibus, Alabama Cancer Database (UALCAN), and The Human Protein Atlas databases.

Thermal Conductivity and Sintering Mechanism of Aluminum/Diamond Composites Prepared by DC-Assisted Fast Hot-Pressing Sintering.

A novel DC-assisted fast hot-pressing (FHP) powder sintering technique was utilized to prepare Al/Diamond composites. Three series of orthogonal experiments were designed and conducted to explore the effects of sintering temperature, sintering pressure, and holding time on the thermal conductivity (TC) and sintering mechanism of an Al-50Diamond composite. Improper sintering temperatures dramatically degraded the TC, as relatively low temperatures (≤520 °C) led to the retention of a large number of pores, while higher temperatures (≥600 °C) caused unavoidable debonding cracks.

Prognostic biomarker NRG2 correlates with autophagy and epithelial‑mesenchymal transition in breast cancer.

Breast cancer (BRCA) is a leading cause of death in women worldwide, accounting for 31% of female cancer. Autophagy plays a crucial role in cancer progression, however, the function of autophagy-related gene neuroregulatory protein 2 (NRG2) in BRCA and its underlying molecular mechanisms remain unclear. In the present study, the expression of the NRG2 gene in BRCA was significantly down-regulated compared with the normal controls.

Colorimetric and electrochemical dual-mode uric acid determination utilizing peroxidase-mimicking activity of CoCu bimetallic nanoclusters.

We present the preparation of CoCu bimetallic nanoclusters (Co@Cu-BNCs) by a hydrothermal and one-step pyrolysis method to build a colorimetric and electrochemical dual-mode sensing platform for uric acid (UA) detection. In the presence of HO, Co@Cu-BNCs with peroxidase-mimicking activity may convert colorless 3,3',5,5'-tetramethylbenzidine (TMB) to blue-colored oxidized TMB (oxTMB). However, due to the inhibitory effect of uric acid (UA) on the oxidation process of TMB, the characteristic absorption peak intensity of oxTMB decreased when UA was added into a mixed solution.

Preparation of Elastic Macroporous Graphene Aerogel Based on Pickering Emulsion Method and Combination with ETPU for High Performance Piezoresistive Sensors.

High-performance pressure sensors provide the necessary conditions for smart shoe applications. In this paper, the elastic Macroporous Graphene Aerogel (MGA) was synthesized via the modified Hummers' method, and it was further combined with Expanded-Thermoplastic polyurethane (ETPU) particles to assemble MGA-ETPU flexible sensors. The MGA-ETPU has a low apparent density (3.

green synthesis of the nanocomposites of MnO/graphene as an oxidase mimic for sensitive colorimetric and electrochemical dual-mode biosensing.

Herein we report the colorimetry and an electrochemical for the determination of dopamine (DA) by using MnO nanoparticles and graphene nanosheets composite (MnO@G) that display oxidase mimicking property. MnO@G could directly oxidize colorless 3,3',5,5'-tetramethylbenzidine (TMB) into a blue product (oxTMB) without extra oxidants such as HO. Nevertheless, the presence of DA will inhibit the TMB oxidation due to the presence of the competitive reaction of MnO@G and DA, giving a product color change from blue to colorless.

[Circular RNA-encoded peptides and proteins: implications to cancer].

Circular RNA (circRNA) is a single-stranded circular closed RNA molecule formed from linear RNA through reverse splicing. circRNAs are stable, highly conserved, and tissue-specific. circRNAs can regulate physiological and pathological processes through various mechanisms such as formation of competing endogenous RNA and interaction with binding proteins.

Effect of active and passive warming on preventing hypothermia and shivering during cesarean delivery: a systematic review and meta-analysis of randomized controlled trials.

Background: Perioperative hypothermia and shivering commonly occur in pregnant women undergoing cesarean section. The warming method is usually used to prevent hypothermia and shivering. However, the effect of active warming (AW) prior to passive warming (PW) on the perioperative outcomes of pregnant women and their offspring remains controversial.

[Exploration of organoid in breast cancer related research].

Breast cancer is the most common cancer in women. At present, the in vivo model and traditional cell culture are mainly used in breast cancer researches. However, as high as 90% clinical trials are failed for drugs explored by the above two methods, due to the inherent species differences between humans and animals, as well as the differences in the tissue structure between organs and cells.
