Timing Matters: How Daily Rhythms Affect Remote Ischemic Postconditioning Therapy for Stroke.

Background: Despite promising preclinical results, remote limb ischemic postconditioning efficacy in human stroke treatment remains unclear, with mixed clinical trial outcomes. A potential reason for translational difficulties could be differences in circadian rhythms between nocturnal rodent models and diurnal humans.

Methods: Male C57BL/6J mice were subjected to transient focal cerebral ischemia and then exposed to remote postconditioning during their active or inactive phase and euthanized at 24 hours and 3 days.

Biological Sex and Cardiovascular Disease Prevention in Systemic Arterial Hypertension.

Biological sex influences the life course development of blood pressure, systemic arterial hypertension, and hypertension-associated complications through neural, hormonal, renal, and epigenetic mechanisms. Sex hormones influence blood pressure regulation through interaction with several main regulatory systems, including the autonomic nervous system, the renin-angiotensin-aldosterone system, endothelin, and renal mechanisms. The modulation of vascular function by sex hormones varies over the lifespan.

Cooperative Enhancement of Aldoxime Dehydratase Stability through Whole-Cell Immobilization and Flow Reactor Integration.

This study investigates the synthesis of aromatic nitriles using an evolved variant of OxdF1 (L318F/F306Y), an aldoxime dehydratase from Pseudomonas putida F1, engineered for improved catalytic efficiency toward benzaldehyde oxime. The double OxdF1 (L318F/F306Y) mutant effectively catalyzes the conversion of various benzaldoxime derivatives to the corresponding nitriles. Due to the enzyme's inherent instability, immobilized whole-cell systems are employed in a flow reactor to improve its stability and broaden its applicability, with the biotransformation of benzaldehyde oxime and 2,6-difluorobenzaldehyde oxime serving as case studies.

Elesclomol-Copper combination synergistically targets mitochondrial metabolism in cancer stem cells to overcome chemoresistance in pancreatic ductal adenocarcinoma.

Pancreatic ductal adenocarcinoma (PDAC) is an aggressive cancer with poor prognosis, partly due to cancer stem cells (CSCs) that drive progression and treatment resistance. We explored the therapeutic potential of inducing cuproptosis, a copper-dependent regulated cell death, in CSC-enriched PDAC models. Using human and murine PDAC models, we evaluated elesclomol, a copper transport enhancer.

Circularly Polarized Luminescence from an Inverted Singlet-Triplet Chiral Dye.

Molecules with an inverted singlet-triplet gap (Δ = - < 0) hold potential for optoelectronic applications as OLEDs and photocatalysis. Despite growing interest, no single-molecule emission from a chiral dye with an inverted gap has been reported, and only one case has shown such emission from supramolecular aggregates. Here, we present the first circularly polarized light emission (CPL) from a chiral molecule exhibiting an inverted singlet-triplet gap.

In-vivo evidence of synucleinopathy in parkinsonism due to VCP mutation.

Multisystem proteinopathy 1 (MSP1) is a rare autosomal dominant disorder caused by mutations in the valosin-containing protein (VCP) gene typically presenting with inclusion body myopathy (IBM), Paget's disease of bone (PDB), frontotemporal dementia (FTD), and amyotrophic lateral sclerosis (ALS). Parkinsonism is a rare feature of MSP1, occurring in 3-4% of cases, with limited post-mortem evidence suggesting neuronal synucleinopathy. We report a case of VCP-related parkinsonism providing the first in vivo demonstration of phosphorylated alpha-synuclein deposition in skin biopsy, a highly sensitive and specific in vivo biomarker of synucleinopathy.

"Dozing off" in the car and excessive daytime sleepiness (EDS) in Parkinson's disease: a survey of 125 patients.

Parkinson's disease patients are at increased risk of road traffic and car accidents and those with excessive daytime sleepiness are specially susceptible. Abnormal scores on the Epworth Sleepiness Scale predicts risk for driving-related somnolence which may cause road traffic accidents in driving patients as many such patients declare dozing of while in a car. Our study estimates that over 40% of patients with daytime somnolence have risks of dozing off in a car.

Immunohistochemistry for PTEN testing in HR +/HER2- metastatic breast cancer.

The PTEN tumor suppressor regulates the PIK3CA/AKT1 pathway, and its inactivation significantly contributes to tumorigenesis and progression in hormone receptor-positive/HER2-negative (HR + /HER2 -) metastatic breast cancer (MBC). In ~ 5% of these patients, PTEN loss, primarily due to gene deletions, leads to aberrant PI3K signaling and enhanced oncogenic potential. Findings from the CAPItello-291 study further establish PTEN together with PIK3CA and AKT1 as a predictive biomarker for Capivasertib, a pan-AKT inhibitor, in these patients.
