Debut of enzyme-responsive anionic cyanine for overlap-free NIR-II-to-I dual-channel tumour imaging.

Bridging the disparity between traditional surgical resection imaging and histopathology, fluorescence imaging is considered a promising tool in disease diagnosis and imaging navigation. Nevertheless, its usefulness is undermined by the variability of single-wavelength fluorescence signals and limited penetration of NIR-I (650-900 nm) bioimaging. In this work, we present a novel NIR-II ratiometric fluorescent probe (CFC-GSH) with γ-glutamyl transpeptidase (GGT) sensitivity for multifunctional bioimaging.

Integrated computational approaches for advancing antimicrobial peptide development.

The increasing prevalence of antimicrobial resistance has intensified the need for novel antimicrobial drugs. Antimicrobial peptides (AMPs) are promising alternative antibiotics due to their broad-spectrum activity and slower resistance development. However, the time-consuming, costly development and challenge of systematic optimization limit their translation into the clinic.

Intraoperative hypotension associated with postoperative acute kidney injury in hypertension patients undergoing non-cardiac surgery: a retrospective cohort study.

Background: Acute kidney injury (AKI) is a common surgical complication and is associated with intraoperative hypotension. However, the total duration and magnitude of intraoperative hypotension associated with AKI remains unknown. In this study, the causal relationship between the intraoperative arterial pressure and postoperative AKI was investigated among chronic hypertension patients undergoing non-cardiac surgery.

Ratiometric and discriminative visualization of autophagic processes with a novel dual-responded lysosome-specific fluorescent probe.

Background: Autophagy is a critical self-eating pathway involved in numerous physiological and pathological processes. Lysosomal degradation of dysfunctional organelles and invading microorganisms is central to the autophagy mechanism and essential for combating disease-related conditions. Therefore, monitoring fluctuations in the lysosomal microenvironment is vital for tracking the dynamic process of autophagy.

De novo design of a novel AIE fluorescent probe tailored to autophagy visualization via pH manipulation.

Background: Macroautophagy is an essential cellular self-protection mechanism, and defective autophagy has been considered to contribute to a variety of diseases. During the process, cytoplasmic components are transported via autophagosomes to acidic lysosomes for metabolism and recycling, which represents application niches for lysosome-targeted fluorescent probes. Additionally, in view of the complexity of the autophagy pathway, it entails more stringent requirements for probes suitable for monitoring autophagy.

Highly selective and sensitive detection of arsenite ions(III) using a novel tetraphenylimidazole-based probe.

More than 200 million people in the world are exposed to areas where the arsenic concentration exceeds the limit allowed for living species, which urges researchers to develop low-cost methods for the selective and fast detection of arsenic ions in environmental samples. Herein, we report a novel tetraphenylimidazole-based probe (TBAB) functionalized with a Schiff base for sensing and detecting arsenic ions in aqueous media. Upon the addition of arsenic ions, an obvious fluorescence change from faint yellow to green was observed visible to the naked eye.

MicroRNA-128-1-5p attenuates myocardial ischemia/reperfusion injury by suppressing Gadd45g-mediated apoptotic signaling.

Myocardial ischemia/reperfusion (I/R) injury is a clinically fatal disease, caused by restoring myocardial blood supply after a period of ischemia or hypoxia. However, the underlying mechanism remains unclear. Recently, increasing evidence reveal that microRNAs (miRs) participate in myocardial I/R injury.

Relationship between Accessory Renal Artery and Clinical Characteristics of Middle-Aged Patients with Primary Hypertension.

Objectives: The association between accessory renal artery (ARA) and hypertension remains not fully understood. We observed the association between ARA and clinical characteristics among middle-aged patients with primary hypertension.

Methods: One hundred and sixty-two middle-aged (mean 39.

Critical roles of microRNA-141-3p and CHD8 in hypoxia/reoxygenation-induced cardiomyocyte apoptosis.

Background: Cardiovascular diseases are currently the leading cause of death in humans. The high mortality of cardiac diseases is associated with myocardial ischemia and reperfusion (I/R). Recent studies have reported that microRNAs (miRNAs) play important roles in cell apoptosis.

Bnip3 mediates doxorubicin-induced cardiomyocyte pyroptosis via caspase-3/GSDME.

Aims: This study was aimed to investigate the role of GSDME-mediated pyroptosis in cardiac injury induced by Doxorubicin (DOX), and to evaluate the role of BH3-only protein Bcl-2/adenovirus E1B 19-kDa-interacting protein 3 (Bnip3) in regulation of DOX-induced pyroptosis.

Main Methods: HL-1 cardiomyocytes and C57BL/6J mice were treated by DOX to establish DOX-induced cardiotoxicity in vitro and in vivo models, respectively. Cell transfection was applied to regulate the expression of caspase-3, GSDME and Bnip3.

Postoperative Pain Management in Total Knee Arthroplasty.

Total knee arthroplasty (TKA) is one of the most common surgeries performed to relieve joint pain in patients with end-stage osteoarthritis or rheumatic arthritis of the knee. However, TKA is followed by moderate to severe postoperative pain that affects postoperative rehabilitation, patient satisfaction, and overall outcomes. Historically, opioids have been widely used for perioperative pain management of TKA.

Feasibility of Screening Primary Aldosteronism by Aldosterone-to-Direct Renin Concentration Ratio Derived from Chemiluminescent Immunoassay Measurement: Diagnostic Accuracy and Cutoff Value.

Objectives: Aldosterone-to-plasma renin activity ratio (ARR) derived from traditional radioimmunoassay (RIA) is widely used to detect primary aldosteronism (PA). Recently, aldosterone-to-direct renin concentration ratio (ADRR), which is calculated by direct renin concentration (DRC) measured by chemiluminescent immunoassay (CLIA), is proposed to replace ARR as the screening test method for PA. The purpose of the present study was to estimate the diagnostic accuracy and cutoff value of ADRR as screening test for PA.

Atypical and delayed de Winter electrocardiograph pattern: A case report.

Rationale: de Winter electrocardiograph (ECG) pattern signifies proximal left anterior descending coronary artery (LAD) occlusion and extensive anterior myocardial infarction, and it is found in about 2% of patients with proximal LAD occlusion. However, it is often unrecognized by physicians. In this case report, we present a patient with chest pain but showing an atypical and delayed de Winter ECG pattern.

NRP1 regulates HMGB1 in vascular endothelial cells under high homocysteine condition.

Endothelial inflammation plays an important role in hyperhomocysteinemia (HHcy)-associated vascular diseases. High mobility group box 1 (HMGB1) is a pro-inflammatory danger molecule produced by endothelial cells. However, whether HMGB1 is involved in vascular endothelial inflammation of HHcy is poorly understood.

Biological functions and clinical significance of the newly identified long non‑coding RNA RP1‑85F18.6 in colorectal cancer.

The biological functions of long non‑coding RNAs (lncRNAs) in cancer have not been fully elucidated. The present study demonstrated that the expression of a newly identified lncRNA, RP1‑85F18.6, was upregulated in colorectal cancer (CRC) tissues and cell lines.

l-Homocysteine-induced cathepsin V mediates the vascular endothelial inflammation in hyperhomocysteinaemia.

Background And Purpose: Vascular inflammation, including the expression of inflammatory cytokines in endothelial cells, plays a critical role in hyperhomocysteinaemia-associated vascular diseases. Cathepsin V, specifically expressed in humans, is involved in vascular diseases through its elastolytic and collagenolytic activities. The aim of this study was to determine the effects of cathepsin V on l-homocysteine-induced vascular inflammation.
