Levosimendan shows protective myocardial characteristics and is administered to enhance cardiac contractility in patients. However, currently little is known about levosimendan's effect on brain. The aim of this pilot study was to investigate the long-term effect of levosimendan on brain and during mild rat sepsis in comparison to its peripheral mode of action. Adult rats (n=40) were divided into four groups with n=10 per group: (I) sham, (II) levosimendan (283 μg/kg body weight i.v.), (III) lipopolysaccharide (LPS, 8 mg/kg body weight i.p.), and (IV) LPS+levosimendan. Levosimendan was given 24h after injecting LPS. Psychometric investigations were conducted using a Morris water maze (MWM) and a holeboard test. In cerebral and splenic tissue, IL-1β, Il-6, TNFalpha levels, and apoptosis were determined; cerebral tissue corticosterone concentration was measured 6 days after injecting LPS. Blood cytokine concentrations were determined 1 day and 6 days after injecting LPS. Rats that received an LPS injection spent more time in the outer zone of the MWM according to increased cerebral corticosterone levels, and showed decreased cognitive abilities. LPS induced a reduction in body weight, increased splenic apoptosis and blood cytokine level. Levosimendan showed anti-inflammatory and anti-apoptotic properties in spleen but failed to show a long-term neuroprotective effect.

Background The escalating global obesity epidemic requires comprehensive investigations for effective weight management strategies. Understanding the patterns, barriers, and facilitators of dietary interventions is crucial for developing effective weight management protocols. This research aims to assess dietary modification interventions among weight loss subjects in Tamilnadu, South India.

Osteoarthritis (OA) affects several joints but tends to be more prevalent in those that are weight-bearing, such as the knees, which are the most heavily loaded joints in the body. The incidence and disability rates of OA have continued to increase and seriously jeopardise the quality of life of middle-aged and older adults. However, OA is more than just a wear and tear disease; its aetiology is complex, and its pathogenesis is poorly understood.

Objectives: This analysis quantifies the potential long-term clinical and cost benefits of early and intensive metabolic control (EIMC) versus conventional management in patients newly diagnosed with type 2 diabetes in Italy.
Methods: The PRIME T2D Model was used to project clinical and cost outcomes over long-term time horizons for a newly diagnosed cohort of patients receiving EIMC or conventional management. EIMC was associated with a mean glycated hemoglobin reduction of 0.

Colitis is an inflammatory disorder of the gastrointestinal tract. A widely consumed dietary nutrient, α-ketoglutarate (α-KG) is known to play a crucial role in cellular metabolism and provide protection to intestinal epithelium under various pathophysiological conditions. In this study, 2,4,6-trinitrobenzenesulfonic acid (TNBS) was used to induce colitis in Wistar rats.
