The cellular utilization of oxygen leads to the generation of free radicals in organisms. The accumulation of these free radicals contributes significantly to aging and several age-related diseases. Angiotensin II can contribute to DNA damage through oxidative stress by activating the NAD(P)H oxidase pathway, which in turn results in the production of reactive oxygen species. This radical oxygen-containing molecule has been linked to aging and several age-related disorders, including renal damage. Considering the role of angiotensin in aging, melatonin might relieve angiotensin-II-induced stress by enhancing the mitochondrial calcium uptake 1 pathway, which is crucial in preventing the mitochondrial calcium overload that may trigger increased production of reactive oxygen species and oxidative stress. This review highlights the role and importance of melatonin together with angiotensin in aging and age-related diseases.

Unlabelled: This study examined the impact of thiazide and RAAS antihypertensive medications vs DHP-RAAS medications on fracture risk. The close alignment of such settings with clinical use, combined with the potential bone benefits of ACEis and ARBs, provides enhanced accuracy in bone health evidence.
Purpose: To determine whether thiazides, combined with either angiotensin-converting enzyme inhibitor (ACEi) or angiotensin II receptor blocker (ARB), offer bone-protective benefits compared with dihydropyridine (DHP) drugs combined with ACEi or ARB.

Background: The renal renin-angiotensin system (RAS) plays a vital part in the control of blood pressure and is known to be affected by aging. This study aimed to investigate the effects of intermittent fasting on age-related hypertension and the expression of local renal RAS components.
Methods: The Wistar rats were categorized into three main age groups (young, middle aged, and elderly) and three dietary treatment models, including ad libitum feeding (AL), every other day fasting (EOD), and one day per week of fasting (FW).

The functional significance of brain asymmetry is still largely unknown. Studying the level of correlation of neuropeptide-degrading activities between subcellular fractions such as synaptosomal, of the left and right hemispheres of male rats during development and aging could provide relevant data on their functional role during these periods. The present study analyzes the level of correlation of a enkephalin- or angiotensin III-degrading activity, such as membrane-bound arginyl-aminopeptidase activity (M-B ArgAP) between the left versus right homogenate and/or synaptosomal subcellular fractions obtained and processed independently from both brain hemispheres during development and aging.

Background: Optimal heart failure (HF) pharmacotherapy (guideline-directed medical therapy and diuretics) in older people with frailty is uncertain due to limited evidence.
Aims: To evaluate utilisation of HF pharmacotherapy and prevalence of polypharmacy, adverse drug events (ADEs), falls, delirium, renal impairment and duration of hospitalisation in older inpatients, according to frailty.
Methods: A retrospective cross-sectional study of the TO HOME cohort of 2000 inpatients ≥75 years admitted for ≥48 h to rehabilitation, geriatric or general medicine from 1 July 2016 to 30 June 2017 across six hospitals in Sydney, Australia.

Introduction: Large-scale trials showed positive outcomes of sodium-glucose cotransporter-2 inhibitors (SGLT2i) in adults with chronic kidney disease (CKD). Whether the use of SGLT2i is safe and effective in patients with the common hereditary CKD Alport syndrome (AS) has not yet been investigated specifically in larger cohorts.
Methods: This observational, multicenter, international study (NCT02378805) assessed 112 patients with AS after start of SGLT2i.
