Background: Traumatic brain injury (TBI) is the damage to the brain caused by external blow or jolt to the head or body. TBI secondarily induces cell damage in the hippocampus. This study aimed to investigate effects of resveratrol treatment histological examination and nuclear factor kappa B (NFκB) expression in hippocampus after TBI.
Materials And Methods: Twenty-four rats were assigned to three groups: sham, TBI and TBI + Resveratrol. TBI was conducted by dropping a 50 g weight from a 1-meter height from a tube to the head of animals. 20 mg/kg resveratrol was orally administered to rats after TBI. Blood was collected to measure malondialdehyde (MDA) and glutathione (GSH) contents. Cerebral tissues were processed for histopathology and furtherly for immunohistochemical analysis.
Results: MDA content was significantly increased and GSH value were significantly decreased in TBI group compared to sham group. Resveratrol treatment significantly improved biochemical scores in TBI + Resveratrol group. Normal histological appearance was observed in hippocampal sections of sham group. In TBI group, neurons in hippocampus were degenerated. Their nuclei were pyknotic. Other neurons and supportive neuroglial cells in hippocampal proper and dentate gyrus were also disrupted. Hippocampal proper integrity was lost with vascular dilatation. NFκB was upregulated in hippocampal neurons of TBI group.
Conclusions: Resveratrol treatment alleviated pathologies and downregulated NFκB expression in hippocampus. TBI caused adverse alterations in free radicals' balance system and histological structures of hippocampus. Resveratrol with its antioxidant and anti-inflammatory effects reduced the damage caused by TBI.

Atomic force microscopy (AFM) has reached a significant level of maturity in biology, demonstrated by the diversity of modes for obtaining not only topographical images but also insightful mechanical and adhesion data by performing force measurements on delicate samples with a controlled environment (e.g., liquid, temperature, pH).

Traumatic brain injury (TBI)-associated neuroinflammation and neurotoxicity can induce gastrointestinal dysfunction through the brain-gut axis. Partially hydrolyzed guar gum (PHGG) was demonstrated to exert beneficial health effects by altering gut microbiota and short-chain fatty acids (SCFAs) production. Our study aimed to explore the effects of PHGG on gastrointestinal dysfunction in TBI mouse models.

Objectives: This study aimed to identify outcome clusters among individuals with traumatic brain injury (TBI), 6 months to 10 years post-injury, in an Australian rehabilitation sample, and determine whether scores on 12 dimensions, combined with demographic and injury severity variables, could predict outcome cluster membership 1 to 3 years post-injury.
Setting: Rehabilitation hospital.
Participants: A total of 467 individuals with TBI, aged 17 to 87 (M = 44.

Objective: Traumatic Brain Injury (TBI) may contribute additional complexity to the clinical picture of mild behavioral impairment (MBI). MBI, a behavioral analog to mild cognitive impairment (MCI), is comprised of five neuropsychiatric domains: decreased motivation, affective dysregulation, impulse dyscontrol, social inappropriateness, and abnormal perception/thought content. We investigated (1) if cross-sectional associations of cognitive status with MBI symptoms differ by TBI status and (2) if prospective associations of MBI domain positivity with incident dementia risk differ by TBI status.

Objective: Elevated intracranial pressure (ICP), a common complication in traumatic brain injuries (TBI), can lead to optic nerve sheath diameter (ONSD) enlargement and flow spectrum changes from the internal carotid artery (ICA) to middle cerebral artery (MCA). This study will investigate the use of Cervical-Cerebral Arterial Ultrasound (CCAU) for non-invasive ICP assessment and evaluating the related indices' clinical utility in TBI patients with decompressive craniotomy (DC).
Methods: ONSD and flow spectrum changes were measured within 24 h after DC in 106 patients via ultrasonic ONSD measurement and CCAU, simultaneously.
