Breaking boundaries: role of the brain barriers in metastatic process.

Fluids Barriers CNS

January 2025

Department of Anatomy, Cellular and Molecular Neurobiology Research Group, Faculty of Medicine, Masaryk University, 625 00, Brno, Czech Republic.

Brain metastases (BMs) are the most common intracranial tumors in adults and occur 3-10 times more frequently than primary brain tumors. Despite intensive multimodal therapies, including resection, radiotherapy, and chemotherapy, BMs are associated with poor prognosis and remain challenging to treat. BMs predominantly originate from primary lung (20-56%), breast (5-20%), and melanoma (7-16%) tumors, although they can arise from other cancer types less frequently.

Shift work schedules alter immune cell regulation and accelerate cognitive impairment during aging.

J Neuroinflammation

January 2025

Department of Neuroscience and Experimental Therapeutics, School of Medicine, Texas A&M Health Science Center, Bryan, TX, 77807-3260, USA.

Background: Disturbances of the sleep-wake cycle and other circadian rhythms typically precede the age-related deficits in learning and memory, suggesting that these alterations in circadian timekeeping may contribute to the progressive cognitive decline during aging. The present study examined the role of immune cell activation and inflammation in the link between circadian rhythm dysregulation and cognitive impairment in aging.

Methods: C57Bl/6J mice were exposed to shifted light-dark (LD) cycles (12 h advance/5d) during early adulthood (from ≈ 4-6mo) or continuously to a "fixed" LD12:12 schedule.

Beijing Minhai Biotechnology Co. Ltd, Beijing 102600, China. Electronic address:

Streptococcus pneumoniae is a major pathogen of bacterial pneumonia, meningitis, sepsis, and otitis media. The pathogenicity of this bacterium is largely attributed to its polysaccharide capsule, a protective layer around bacterial cell that enables bacteria to resist against host defense. Capsular polysaccharides (CPSs) of S.

Sexually transmitted proctitis, a prevalent concern among men who have sex with men (MSM) is frequently caused by a range of pathogens, including herpes simplex virus (HSV), and While HSV-associated proctitis typically presents with visible lesions, cases without external manifestations remain evasive. We report the case of an MSM in his early 30s presenting with dyschezia and perineal discomfort after unprotected anoreceptive intercourse. Despite initial inconspicuous findings, rectal swabs revealed HSV-2 infection.
