On-Chip Photonic Simulating Band Structures toward Arbitrary-Range Coupled Frequency Lattices.

Photonic simulators are increasingly used to study physical systems for their affluent manipulable degrees of freedom. The advent of photonic chips offers a promising path towards compact and configurable simulators. Thin-film lithium niobate chips are particularly well suited for this purpose due to the high electro-optic coefficient, which allows for the creation of lattices in the frequency domain.

Rutin Synergizes with Colistin to Eradicate Salmonellosis in Mice by Enhancing the Efficacy and Reducing the Toxicity.

The wide dissemination of multidrug-resistant (MDR) Gram-negative bacteria poses a significant global health and security concern. As developing new antibiotics is generally costly, fastidious, and time-consuming, there is an urgent need for alternative therapeutic strategies to address the gap in antibiotic discovery void. This study aimed to investigate the activity of colistin (CS) in combination with a natural product, rutin (RT), to combat against Typhimurium ( Tm) in vitro and in vivo.

Metabolic disruption exacerbates intestinal damage during sleep deprivation by abolishing HIF1α-mediated repair.

Sleep deprivation (SD) has been reported to induce intestinal damage by several mechanisms, yet its role in modulating epithelial repair remains unclear. In this study, we find that chronic SD leads to colonic damage through continuous hypoxia. However, HIF1α, which generally responds to hypoxia to modulate barrier integrity, was paradoxically dysregulated in the colon.

Evaluating the impact of treatment sequencing on outcomes in hepatocellular carcinoma: a comparative analysis of TACE and systemic therapies.

This study aimed to evaluate how the timing of transarterial chemoembolization (TACE) relative to systemic therapy (tyrosine-kinase inhibitors [TKIs] and immune checkpoint inhibitors [ICIs]) influences oncological outcomes in patients with hepatocellular carcinoma (HCC). A retrospective analysis was conducted on HCC patients treated with TACE plus TKIs and ICIs from January 2018 to February 2023. We compared objective response rate (ORR), disease control rate (DCR), overall survival (OS), and progression-free survival (PFS) between patients receiving TACE before versus after systemic therapies.

Preparation of micron-sized benzamidine-modified magnetic agarose beads for trypsin purification from fish viscera.

The effective method for trypsin purification should be established because trypsin has important economic value. In this work, a novel and simple strategy was proposed for fabricating micron-sized magnetic FeO@agarose-benzamidine beads (MABB) with benzamidine as a ligand, which can efficiently and selectively capture trypsin. The micro-sized MABB, with clear spherical core-shell structure and average particle size of 6.

Colonization ability and uniformity of resources and environmental factors determine biological homogenization of soil protists in human land-use systems.

Humans have substantially transformed the global land surface, resulting in the decline in variation in biotic communities across scales, a phenomenon known as "biological homogenization." However, different biota are affected by biological homogenization to varying degrees, but this variation and the underlying mechanisms remain little studied, particularly in soil systems. To address this topic, we used metabarcoding to investigate the biogeography of soil protists and their prey/hosts (prokaryotes, fungi, and meso- and macrofauna) in three human land-use ecosystem types (farmlands, residential areas, and parks) and natural forest ecosystems across subtropical and temperate regions in China.

Unraveling the biological link between diabetes mellitus and prostate cancer: Insights and implications.

This article is a comprehensive study based on research on the connection between diabetes mellitus (DM) and prostate cancer (PCa). It investigates the potential role of DM as an independent risk factor for PCa, delving into the biological links, including insulin resistance and hormonal changes. The paper critically analyzes previous studies that have shown varying results and introduces mendelian randomization as a method for establishing causality.

Association between tobacco exposure and bladder cancer recurrence: A systematic review and meta-analysis.

Background: However, the connection between smoking and the prognosis of patients with bladder cancer remains unclear.

Aim: To determine whether smoking is linked to the recurrence and progression of bladder cancer.

Methods: As of July 20, 2022, relevant English-language research was identified by searching PubMed, the Web of Science, and the Cochrane Library.

Colorectal cancer screening: The value of early detection and modern challenges.

The screening of colorectal cancer (CRC) is pivotal for both the prevention and treatment of this disease, significantly improving early-stage tumor detection rates. This advancement not only boosts survival rates and quality of life for patients but also reduces the costs associated with treatment. However, the adoption of CRC screening methods faces numerous challenges, including the technical limitations of both noninvasive and invasive methods in terms of sensitivity and specificity.

Estrogen restores disordered lipid metabolism in visceral fat of prediabetic mice.

Background: Visceral obesity is increasingly prevalent among adolescents and young adults and is commonly recognized as a risk factor for type 2 diabetes. Estrogen [17β-estradiol (E2)] is known to offer protection against obesity diverse me-chanisms, while its specific effects on visceral adipose tissue (VAT) remain to be fully elucidated.

Aim: To investigate the impact of E2 on the gene expression profile within VAT of a mouse model of prediabetes.

The Predictive Value of Geriatric Nutritional Risk Index Combined with the GRACE Score in Predicting the Risk of One Year Poor Prognosis in Elderly Patients with Non-ST Segment Elevation Myocardial Infarction After PCI.

Background: As a nutritional indicator, a lower level of geriatric nutritional risk index (GNRI) has been suggested as a predictor for poor prognosis in acute coronary syndrome (ACS). However, whether GNRI could improve the predictive value of the Global Registry of Acute Coronary Events (GRACE) score for the prognosis in elderly patients with non-ST segment elevation myocardial infarction (NSTEMI) after PCI remains unclear.

Methods: A total of 446 elderly patients with NSTEMI after percutaneous coronary intervention (PCI) were consecutively enrolled.

Apoptotic body-inspired nanotherapeutics efficiently attenuate osteoarthritis by targeting BRD4-regulated synovial macrophage polarization.

Bromodomain-containing protein 4 (BRD4) is the most well-studied BET protein that is important for the innate immune response. We recently revealed that targeting BRD4 triggers apoptosis in tumor-associated macrophages, but its role in synovial macrophages and joint inflammation is largely unknown. Herein, we demonstrated that BRD4 was highly expressed in the iNOS-positive M1 macrophages in the human and mouse osteoarthritis (OA) synovium, and conditional knockout of BRD4 in the myeloid lineage using Lyz2-cre; BRD4 mice significantly abolished anterior cruciate ligament transection (ACLT)-induced M1 macrophage accumulation and synovial inflammation.
