Toxicity Differences Between Microplastics and Nanoplastics in Organs: From Molecular Mechanisms to Potential Therapeutic Strategies

Med Research, EarlyView.
This review systematically compares the size‐dependent toxicity of microplastics and nanoplastics in the intestine, liver, kidney, lung, and brain. Particle size determines bioavailability, barrier penetration, and injury mechanisms. Because of their small size and high surface reactivity, NPs readily cross the intestinal epithelium and blood–brain ...

Early Circulatory and Red Blood Cell Aggregation Changes During a Short‐Term Bone‐Specific Exercise Program in Community‐Dwelling Older Women: An Exploratory Pilot Study

Medicine Advances, EarlyView.
A 6‐week bone‐specific exercise program in community‐dwelling older women was associated with increased peripheral blood flow and improved red blood cell aggregation. In contrast, calcaneal quantitative ultrasound showed no significant change in the speed of sound.

Simplified Anisotropic IVIM Using Spherical Means and an Application in the Placenta

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To reduce the complexity associated with anisotropic IVIM modeling, we derived two simplified diffusion MRI models that map the apparent diffusivity, relative proportions, and anisotropy of perfusion‐ and diffusion‐related signal components and demonstrated them in placenta scans.

Adipose‐derived small extracellular vesicles exacerbate microvascular dysfunction in heart failure with preserved ejection fraction via mmu‐miR‐582‐3p‐mediated Rap1b suppression

Interdisciplinary Medicine
Heart failure with preserved ejection fraction (HFpEF) is characterized by diastolic dysfunction despite a preserved left ventricular ejection fraction, and visceral adipose tissue is implicated in its pathogenesis.

Chronic high‐altitude exposure and intracerebral hemorrhage: A novel perspective from the vascular‐immune‐neuronal network

Neuroprotection, EarlyView.
Long‐term chronic high‐altitude hypobaric hypoxia increases susceptibility to ICH, particularly among migrant populations lacking EPAS1/SENP1 adaptive genetic variants relative to high‐altitude indigenous residents. Persistent hypoxia initiates blood–brain barrier (BBB) breakdown, aberrant glial and immune activation, and progressive neuronal injury ...

Evaluating the efficacy of obturator cryoneurolysis for hip adductor spasticity: An observational, prospective study

PM&R, EarlyView.
Abstract Background Hip adductor spasticity is a common affliction among patients with disorders of the central nervous system. Cryoneurolysis is a novel intervention for spasticity involving the application of extreme cold to a nerve. This induces axonal breakdown, relieving spasticity.
