Versatile adhesive skin enhances robotic interactions with the environment.

Electronic skins endow robots with sensory functions but often lack the multifunctionality of natural skin, such as switchable adhesion. Current smart adhesives based on elastomers have limited adhesion tunability, which hinders their effective use for both carrying heavy loads and performing dexterous manipulations. Here, we report a versatile, one-size-fits-all robotic adhesive skin using shape memory polymers with tunable rubber-to-glass phase transitions.

Inferential statistics for cardiothoracic surgeons: Part 3 - drawing valid conclusions from clinical data.

Inferential statistics enable researchers to make predictions about a population based on sample data. This involves hypothesis testing where the null hypothesis assumes no effect, and the alternative hypothesis suggests a significant effect. Testing requires assumptions like normality and independence to be validated using tests like Shapiro-Wilk or Levene's for normality and variance.

Determinants of mortality after massive transfusion - A prospective study.

Introduction: Massive hemorrhage calls for massive transfusions (MTs) to maintain adequate hemostasis. Massive transfusion protocols (MTPs) are the appropriate treatment strategy for such patients replacing conventional use of crystalloids. These help in standardizing and optimizing the delivery of blood components in a well-balanced ratio.

Better Outcomes for Ovarian Cancer Associated With the Detection of Anti-EBV TCR CDR3s: Potential Relevance to Diffuse Large B-Cell Lymphoma.

Objectives: Given the ongoing challenges regarding the specific roles of viral infections in cancer etiology, or as cancer co-morbidities, this study assessed potential associations between anti-viral, T-cell receptor (TCR) complementarity domain region-3 (CDR3s), and clinical outcomes for ovarian cancer.

Methods: TCR CDR3s were isolated from ovarian cancer specimens for a determination of which patients had anti-viral CDR3s and whether those patients had better or worse outcomes.

Results: Analyses revealed that patients with exact matches of anti-Epstein-Barr virus (EBV) CDR3 amino acid sequences exhibited better outcomes for both overall and disease-specific survival.

B cells enhance IL-1 beta driven invasiveness in triple negative breast cancer.

Triple-negative breast cancer (TNBC) is an aggressive subtype often characterized by high lymphocyte infiltration, including tumor-infiltrating B cells (TIBs). These cells are present even in early stages of TNBC and associated with microinvasion. This study shows that co-culturing TNBC cells with B cells increases Interleukin-1β (IL-1β) expression and secretion.

At the primary analysis, olaparib treatment demonstrated activity across all cohorts, with greatest efficacy in terms of objective response rate and progression-free survival observed in the g/sBRCAm cohorts. The authors report final overall survival (OS).

Global Health Inequities in Electrophysiology Care: A State-of-the-Art Review.

This state-of-the-art review examines disparities in the diagnosis, management, and outcomes of cardiac arrhythmias globally. These arrhythmias include atrial fibrillation, ventricular tachyarrhythmias underlying sudden cardiac death, and bradyarrhythmias associated with sinus node and atrioventricular node disease. Arrhythmias in low- and middle-income countries often result in higher mortality rates due to complex and poorly documented risk factors, lack of clinical expertise among health care personnel, lack of sufficient infrastructure, and challenges in access to care.

Liver injury in tuberculosis patients, associated with noncompliance with treatment, is further exacerbated by viral hepatitis, which not only directly harms the liver but also increases susceptibility to drug-induced liver injury. The aim of this study was to analyze the associated risk factors for viral hepatitis in tuberculosis patients. This systematic review and meta-analysis adhere to the PRISMA 2020 statement, and the protocol has been registered with PROSPERO (CRD42023477241).

Dual sgRNA-directed knockout gene expression using CRISPR/Cas9 technology for editing gene in triple-negative breast cancer.

Clustered regularly interspaced short palindromic repeats (CRISPR)-associated nuclease 9 (CRISPR/Cas9) offers a robust approach for genome manipulation, particularly in cancer therapy. Given its high expression in triple-negative breast cancer (TNBC), targeting with CRISPR/Cas9 holds promise as a therapeutic strategy. The aim of this study was to design specific single guide ribonucleic acid (sgRNA) for CRISPR/Cas9 to permanently knock out the gene, exploring its potential as a therapeutic approach in breast cancer while addressing potential off-target effects.

Integrating epigenetic modification and stem cell therapy strategies: A novel approach for advancing Alzheimer's disease treatment - A literature review.

Alzheimer's disease (AD) is the most frequent form of dementia and represents an increasing global burden, particularly in countries like Indonesia, where the population has begun to age significantly. Current medications, including cholinesterase inhibitors and NMDA receptor antagonists, have modest effects on clinical symptoms in the early to middle stages, but there is no curative treatment available so far despite progress. Activating or repressing epigenetic modifications, including DNA methylation, histone modification and microRNA regulation, appears to play an important role in AD development.

Computational Insights into "Lone Pair-Lone Pair Interaction-Controlled" Isomerization in the Asymmetric Total Syntheses of (+)-3-()-Laureatin and (+)-3-()-Isolaureatin.

Described herein is our computational study to rationalize the stereoselective epimerization of α,α'--disubstituted oxolane and oxetane ketones and to the corresponding α,α'- ketones and reported in our previous total syntheses of (+)-3-()-isolaureatin () and (+)-3-()-laureatin (). Density functional theory (DFT) calculations using appropriately truncated models revealed that the α,α'- ketones are more stable than the α,α'- ketones, in very good agreement with experimental results. The computational results showed that the isomer with a longer interatomic distance between the two ring oxygen atoms was lower in energy, which suggested the presence of repulsive interactions between those oxygen atoms.

Transcriptome profiling of aged-mice ovaries administered with individual ingredients of Samul-tang.

Samul-tang (SM) is a traditional multi-ingredient herbal formula that is widely used in clinical practice for treating female infertility. Despite its known therapeutic benefits, the complexity of its action mechanisms owing to the combination of multiple compounds has limited its research and integration into modern pharmacological science. To address this challenge, we identified 38 herbal compounds as the major ingredients in SM and generated their transcriptome data from aged-mice ovaries by administering these individual compounds.

A histochemical approach to activity-based copper sensing reveals cuproplasia-dependent vulnerabilities in cancer.

Copper is an essential nutrient for sustaining vital cellular processes spanning respiration, metabolism, and proliferation. However, loss of copper homeostasis, particularly misregulation of loosely bound copper ions which are defined as the labile copper pool, occurs in major diseases such as cancer, where tumor growth and metastasis have a heightened requirement for this metal. To help decipher the role of copper in the etiology of cancer, we report a histochemical activity-based sensing approach that enables systematic, high-throughput profiling of labile copper status across many cell lines in parallel.
