Acute effects of L-DOPA/carbidopa/buspirone (Spinalon™) on rhythmic electrical activity of the lumbosacral spinal cord in cats.

Discovered by Guertin and colleagues in 2004, Spinalon™ is a fixed-drug combination (L-DOPA, carbidopa, and buspirone) that can acutely induce temporary episodes of rhythmic locomotor-like activity in complete or near-complete spinal cord-injured (SCI) subjects. However, little is known about the mechanisms of action or the direct effects of Spinalon™ on neural elements of the central pattern generators (CPGs). Our study aims at characterizing the effects of Spinalon™ on electrical activity of the spinal cord in segmental areas known to contain key rhythmogenic elements of the CPGs (i.

The Geriatric Patient: Frailty, Prehabilitation, and Postoperative Delirium.

Historically and for ease of classification, the geriatric patient has received a chronologic definition of a person 65 years and older. Chronologic age remains an independent risk of postoperative complications and adverse surgical outcomes. Frailty is an expression of an individual's biological age and as such a more reliable determination of their vulnerabilities or resilience to stress.

Power spectral density and similarity analysis of COVID-19 mortality waves across countries.

Background: During the COVID-19 pandemic, the Johns Hopkins University Center for Systems Science and Engineering (CSSE) established a comprehensive database detailing daily mortality rates across countries. This dataset revealed fluctuating global mortality trends attributable to COVID-19; however, the specific differences and similarities in mortality patterns between countries remain insufficiently explored. Consequently, this study employs Fourier and similarity analyses to examine these patterns within the frequency domain, thereby offering novel insights into the dynamics of COVID-19 mortality waves across different nations.
