Cerebrospinal Fluid Composition of Infants with Ischemic Stroke.

Objective: To characterize the cerebrospinal fluid (CSF) of infants with stroke and compare those findings to the CSF of infants with bacterial meningitis and neither condition in the first 14 postnatal days.

Study Design: Cohort study of 30,092 infants who received a lumbar puncture in the first 14 postnatal days discharged from >300 neonatal intensive care units from 1997-2020. CSF parameters were compared between infants with stroke and bacterial meningitis using non-parametric hypothesis testing and quantile regression.

Indoor carbon monoxide exposures in a retail occupancy.

In a two-story retail mall in the Southeastern United States, employees within Store A (located on the second level) began to feel headaches and general unease and discussed the symptoms among themselves. Approximately 1.5 hr later, an employee called 9-1-1.

Effects of implant status and breed type on feedlot performance, carcass characteristics, sera metabolites, and immunohistochemical responses in finishing steers.

The number of beef × dairy animals entering feedlots has increased, but the response of beef × dairy cattle to growth-promoting implants has not been well characterized. The objective of this study was to evaluate the effects of breed type and implant administration on live performance, carcass characteristics, sera metabolites, and immunohistochemical (IHC) outcomes. Forty-eight steers (average body weight [BW] = 417±22 kg) were sorted by breed into groups of predominantly Angus (B), black-hided beef × primarily Holstein (B×D), or Holstein (D), and half of the steers within each breed type were administered a steroidal implant.

Extracellular vimentin amplifies inflammation: Perspectives for immune injury and therapeutics for periodontitis.

Periodontitis is an inflammatory disease triggered by microbial biofilms that promote immune dysfunction and tissue destruction of tooth-supporting tissues. The search for soluble mediators that amplify inflammatory responses and matrix degradation in periodontal tissues has implicated extracellular vimentin (ECV) as a signaling ligand and damage-associated molecular pattern in the pathogenesis of periodontitis. Intracellular vimentin filaments are essential for the structural integrity of cells and the preservation of matrix homeostasis.
