Background and Objectives: Rosiridin is a monoterpene with outstanding monoamine inhibitory activity that is useful to treat depressive episodes and rapid-onset dementia. The current investigation aims to evaluate the neurologically protective impact of rosiridin, which opposes aluminum chloride (AlCl3) and causes memory dysfunction in rats. Materials and Methods: Memory impairment was developed in Wistar rats by administering AlCl3 (100 mg/kg p.o.) orally for 42 days and then supplemented with rosiridin at 10 and 20 mg/kg/p.o. ⋯ Results: The rosiridin-treated group significantly improved in terms of behavioral parameters, including in the Y-maze, Morris Water Maze, and open field tests. Further, rosiridin restored biochemical parameters, including NO, oxidative stress AChE, BuChE, antioxidants, neurotransmitters, IL-6, IL-1β, TNF-α, BNDF, NFᴋB, PI3K, and pAkt compared to AlCl3. Conclusions: The current investigation reveals that rosiridin could ameliorate the impairment of memory that AlCl3 causes in rats via improvements in behavioral and restored biochemical parameters.

Background and Objectives: Cardiac transplantation represents the option for patients with end-stage heart failure (HF), providing the best survival rate. However, the postoperative complications of transplant patients remain a challenge for clinicians. The objective of our study was to evaluate the effect of preoperative chronic HF treatment on the occurrence of in-hospital complications. ⋯ Moreover, Carvedilol therapy represented a protective factor against early AKI. Pre-transplant Spironolactone was associated with lower event rates of AGR, in contrast to ACEI treatment. Prospective studies with larger cohorts are needed in order to draw drastic conclusions.

Background and Objectives: Alzheimer's disease (AD) is the most common neurodegenerative disorder in the world. Due to failure of the traditional drugs to produce a complete cure for AD, the search for new safe and effective lines of therapy has attracted the attention of ongoing research. Canagliflozin is an anti-diabetic agent with proven efficacy in the treatment of neurological disorders in which mitochondrial dysfunction, oxidative stress, apoptosis, and autophagy play a pathophysiological role. ⋯ Results: Canagliflozin administered to aluminium chloride-treated animals induced dose-dependent normalisation in the behavioural tests, augmentation of the antioxidant defence mechanisms, inhibition of TXNIP/NLRP3 inflammasome signalling, modulation of the SIRT1/HMGB1 axis, interference with the pro-inflammatory and the pro-apoptotic mechanisms, and restoration of the mitochondrial functions and autophagy in the hippocampal tissues to approximately baseline values. In addition, canagliflozin exhibited an interesting dose-dependent ability to repress aluminium chloride-induced histopathological changes in the brain. Conclusions: The effects of canagliflozin on oxidative stress, mitochondrial functions, inflammatory pathways, and autophagy signals may open new gates towards the mitigation of the pathologic features of AD.

Backgroud and Objective: The aim of this study was to evaluate the psychometric properties of SAVE-6 in the medical student population and assess its gender invariance. Subjects and Methods: The sample consisted of 320 medical students aged 18-23 years (153 men and 167 women) who completed an anonymous online questionnaire. Data collection took place in June 2024. ⋯ Data also revealed that they were not equal in relation to gender. Specifically, the scalar invariance revealed significant differences by items between men and women in anxiety. Conclusions: This scale can be applied to medical students as a reliable and valid instrument to assess the anxiety response to disease contagion in future health professionals.
