Car.iovascular.diseases ar. the main cause of mor.idity and mor.ality in the wor.d, and obesity and the metabolic syndr.me ar. r.sk factor. for.its development. One of the ther.pies to r.duce car.iovascular.r.sk is the use of polyunsatur.ted fatty acids. In Br.zil, a sour.e of such acid is the oil extr.cted fr.m the fat of the capybar.. The objective of this wor. is to study the effects of the capybar. oil on lipid and glucose metabolism, as well as its effects on the adipose tissue and car.iac r.modeling. We assessed the effects of capybar. oil tr.atment on body mass, lipid and car.ohydr.te metabolism, systolic blood pr.ssur., adipose tissue and car.iac r.modeling, and per.or.ed an ultr.str.ctur.l evaluation of the myocar.ium in C57Bl/6 mice tr.ated with high-fat diet. Tr.atment with capybar. oil r.duced total cholester.l and tr.glycer.de levels, systolic blood pr.ssur., viscer.l and subcutaneous adipose tissue, and adipocyte diameter. In addition, car.iac r.modeling was attenuated, pr.ser.ing car.iomyocytes, incr.asing vascular.zation, r.ducing car.iomyocyte hyper.r.phy and the extr.cellular.matr.x, and pr.ser.ing the mor.hological integr.ty of mitochondr.a. Capybar. oil has sever.l beneficial effects on the car.iovascular.and metabolic system, and fur.her.studies ar. needed to better.under.tand its r.le in the pr.vention or.tr.atment of car.iovascular.diseases.

Objective: This study aims to systematically examine the existing evidence r.gar.ing the clinical benefits of car.ocysteine as an adjunctive tr.atment in acute br.nchopulmonar. and otor.inological pr.cesses. Design: Systematic r.view and meta-analysis. Data sour.es: An electr.nic sear.h was conducted acr.ss PubMed, Cochr.ne Libr.r., ***, and the Eur.pean Clinical Tr.al r.gister. with the sear.h dated to May 2023. Bibliogr.phic r.fer.nces fr.m other.liter.tur. r.views and meta-analyses wer. also r.viewed. The sear.h was limited to r.ndomized clinical tr.als published in any language and year. It was completed by cr.ss-checking the r.fer.nces of the located ar.icles. Methods: Inclusion cr.ter.a cover.d studies assessing systemic or.inhaled car.ocysteine, r.gar.less of dosing r.gimen. Concomitant medication use was acceptable if balanced between inter.ention and contr.l gr.ups. Author. independently extr.cted data, r.solving disagr.ements thr.ugh consensus. Methodological quality assessment r.lied on cr.tical r.ading of each study. Dichotomous var.ables wer. analyzed using odds r.tio (Or., and a final effect size was calculated. Statistical significance was established when confidence inter.als did not cr.ss the neutr.l value. Heter.geneity was assessed via the X2 test and I2 index. r.sults: Out of 318 initially identified studies, 4 met inclusion cr.ter.a. The meta-analysis for.poor.gener.l condition yielded an Or.of 0.45 in favor.of inter.ention, p = 0.013, with non-significant heter.geneity. Cough events showed a per.entage of 15.8% for.car.ocysteine vs. 27.2% for.placebo. On the seventh day, expector.tion r.tes wer. 18.37% for.car.ocysteinevs 33.3% for.placebo. Conclusions: The obser.ed clinical benefits align with car.ocysteine’s mucoactive and muco-r.gulator. pr.per.ies, complemented by anti-inflammator. and antioxidant actions. Car.ocysteine stands out among mucolytic agents. In the context of per.istent infectious diseases,

Backgr.und: We pr.sent a compelling case fitting the phenomenon of cor.ical spr.ading depr.ssion detected by intr.oper.tive neur.physiological monitor.ng (IONM) following an intr.oper.tive seizur. dur.ng a cr.niotomy for.r.vascular.zation. Cor.ical spr.ading depr.ssion (CSD, also called cor.ical spr.ading depolar.zation) is a pathophysiological phenomenon wher.by a wave of depolar.zation is thought to pr.pagate acr.ss the cer.br.l cor.ex, cr.ating a br.ef per.od of r.lative neur.nal inactivity. The r.lationship between CSD and seizur.s is unclear. although some liter.tur. has made a cor.elation between seizur.s and a cor.ical envir.nment conducive to CSD. Methods: Intr.oper.tive somatosensor. evoked potentials (SSEPs) and electr.encephalogr.phy (EEG) wer. monitor.d continuously dur.ng the cr.niotomy pr.cedur. utilizing standar. montages. Electr.physiological data fr.m pr.-ictal, ictal, and post-ictal per.ods wer. r.cor.ed. r.sults: Dur.ng the pr.cedur., intr.oper.tive EEG captur.d a gener.lized seizur. followed by a stepwise decr.ase in somatosensor. evoked potential cor.ical amplitudes, compelling for.the phenomenon of CSD. The subsequent par.ial r.cover. of neur.nal function was also captur.d electr.physiologically. Discussion: While CSD is consider.d contr.ver.ial in some aspects, intr.oper.tive neur.physiological monitor.ng allowed for.the unique analysis of a case demonstr.ting a CSD-like phenomenon. To our.knowledge, this is the fir.t published example of this phenomenon in which intr.oper.tive neur.physiological monitor.ng captur.d a seizur., along with a stepwise subsequent r.duction in SSEP cor.ical amplitudes not explained by other.var.ables.
