Staging concept for aging management: Definition, mechanism, and coping strategies

VIEW, EarlyView.
We divided the overall aging stage into “pre‐aging”, “aging compensation”, and “aging disability”. For each stage, we delineate the clinical presentations, biological phenomena, theoretical underpinnings, and key management priorities. Abstract Aging, as a gradual and largely irreversible biological process, characterized by declining organismal ...

Sensory Biology of the Franciscana (Pontoporia blainvillei, Pontoporiidae, Cetartiodactyla): Ontogenetic Modifications of Vibrissae and Vibrissal Crypts

Integrative Zoology, EarlyView.
The transition of cetaceans from a terrestrial to an aquatic environment involved a crucial sensory adaptation to environments with limited visibility. Vibrissae, important mechanoreceptors, undergo an ontogenetic transformation in odontocetes. This research describes the histomorphology of vibrissae and crypts at different developmental stages ...

Infection control in the brain and the eye

Acta Ophthalmologica, EarlyView.
Abstract The Central Nervous System (CNS), comprising the brain and the eye, is considered to have a ‘privileged’ mechanism for dealing with immunological challenge (immune privilege, IP). CNS IP has been revealed through experiments using foreign protein antigens and cell and tissue alloantigens (grafts), but evidence for a role for IP in modulating ...

Structural characterization of the human cerebral myelin sheath by small angle scattering

, 2008
Myelin is a multi-lamellar membrane surrounding neuronal axons and increasing their conduction velocity. When investigated by small-angle x-ray scattering (SAXS), the lamellar quasi-periodical arrangement of the myelin sheath gives rise to distinct peaks,

Human brain matters: Navigating the neuropathology of COVID‐19

Brain Pathology, EarlyView.
Severe COVID‐19 is associated with vascular dysregulation and chronic neuroinflammation, leading to axonal injury and neurodegeneration. In long COVID or PASC, persistent alterations in neuroimaging and biofluid biomarkers reflect ongoing neuronal damage and neuroinflammation, contributing to long‐term neurological symptoms including fatigue, cognitive

Dysregulated TIE‐2 expression is associated with blood‐brain barrier leakiness and Alzheimer's disease‐related neuropathology

Brain Pathology, EarlyView.
Ince et al., have analysed TIE‐1 and ‐2 expression in human brain tissue, including microvessel‐enriched fractions (MVF) and covering a spectrum of AD‐associated pathology, and in CSF from independent cohorts spanning a clinical spectrum from normal cognition to AD.

Academic Achievement Test for Anatomy of the Neck: Validity and Reliability Analysis

European Journal of Dental Education, EarlyView.
ABSTRACT Objective Anatomy education remains a fundamental component of medical and dental curricula, and mastering neck anatomy is particularly challenging due to its structural complexity and clinical relevance. Despite its importance, there is a limited number of validated instruments specifically designed to assess academic achievement in neck ...

ErbB2 signaling in Schwann cells is mostly dispensable for maintenance of myelinated peripheral nerves and proliferation of adult Schwann cells after injury [PDF]

, 2006
Neuregulin/erbB signaling is critically required for survival and proliferation of Schwann cells as well as for establishing correct myelin thickness of peripheral nerves during development.

Electroacupuncture and category IV LASER for treating suprascapular neuropathy in a two‐year‐old Arabian filly

Equine Veterinary Education, EarlyView.
Summary A 2‐year‐old Arabian filly presented with acute onset grade 4/5 (AAEP) right forelimb lameness and hindlimb ataxia following a collision with another horse and subsequent fall. The right forelimb lameness was associated with marked scapulohumeral joint instability.
