BACKGROUND: Aging is a natural part of human life. However, recent discoveries indicate that pharmacological approaches used for the improvement and possibly, for the delay of the aging process, might shed a new light on this topic. This might obviously contribute to the extension of the active life of older people and maintenance of their quality of life, which could consequently reduce both social and economic burden of each country, especially the developed ones. OBJECTIVE: The purpose of this study is to explore pharmacological discoveries which may help to the delay or improvement of the aging process...

Aging is now at the forefront of major challenges faced globally, creating an immediate need for safe, widescale interventions to reduce the burden of chronic disease and extend human healthspan. Metformin and rapamycin are two FDA-approved mTOR inhibitors proposed for this purpose, exhibiting significant anti-cancer and anti-aging properties beyond their current clinical applications. However, each faces issues with approval for off-label, prophylactic use due to adverse effects. Here, we initiate an effort to identify nutraceuticals-safer, naturally-occurring compounds-that mimic the anti-aging effects of metformin and rapamycin without adverse effects...

The overlap of multiple liver diseases can cause the disease activity and severity to worsen rapidly in some cases. We rarely see patients with non-alcoholic steatohepatitis (NASH) with overlapping autoimmune hepatitis (AIH). A 64-year-old woman who had been prescribed oral drugs to treat diabetes and hypertension (metformin 500 mg/day and voglibose 0.9 mg/day, and termisartan 40 mg/day and amlodipine 5 mg/day, respectively) was diagnosed with NASH with histological confirmation. At 68 years of age, her liver injury worsened with an IgG of 2,871 mg/dL and a high serum anti-nuclear antibody (ANA) level of 2,560...

BACKGROUND: A high fat diet is associated with risk of benign prostatic hyperplasia (BPH). However, whether hyperlipidemia is associated with BPH remains unclear. This population-based cohort study elucidated whether hyperlipidemia is associated with an increased risk of BPH. METHODS: We used a new-exposure design and analyzed data retrieved from the Taiwan National Health Insurance Database between January 1, 2000 and December 31, 2013. The cohort of men with newly diagnosed hyperlipidemia and the age- and index-date-matched (1:3) nonhyperlipidemia cohort were tracked for incidence of BPH during a 1- to 14-year follow-up...

BACKGROUND: Postoperative atrial fibrillation (AF) commonly occurs in cardiac surgery patients. Studies suggest inflammation and oxidative stress contribute to postoperative AF development in this patient population. Metformin exerts an anti-inflammatory effect that reduces oxidative stress and thus may play a role in preventing postoperative AF. METHODS: We conducted a matched, retrospective cohort study of diabetic patients' age ≥18 undergoing a coronary artery bypass graft (CABG) and/or cardiac valve surgery from January 1, 2009, to November 30, 2014...

BACKGROUND: While most guidance recommends the use of insulin in women whose pregnancies are affected by pre-existing diabetes, oral anti-diabetic agents may be more acceptable to women. The effects of these oral anti-diabetic agents on maternal and infant health outcomes need to be established in pregnant women with pre-existing diabetes or impaired glucose tolerance, as well as in women with previous gestational diabetes mellitus preconceptionally or during a subsequent pregnancy. This review is an update of a review that was first published in 2010...

BACKGROUND: Cardiovascular complications associated with expensive noninsulin agents for type 2 diabetes are the focus of concern in light of the risk of kidney dysfunction with aging. Head-to-head comparisons are unavailable to guide the choice of new drugs for hyperglycemia in patients with type 2 diabetes, decreased estimated glomerular filtration rate (eGFR) and increased cardiovascular risk. A first approach would be to document current medication choices. METHODS: All prescriptions for 10 151 patients (5623 males/4528 females) with both type 2 diabetes and hypertension seen two or  more times during a 5-year period (2007-12) at Joslin Diabetes Center were evaluated...

Recent studies have demonstrated that stromal derived factor-1α (SDF-1α) is a substrate of dipeptidyl-peptidase-4 (DPP-4) inhibitors. It has also been shown that SDF-1α shares anti-apoptotic as well as nephroprotective properties and exerts a beneficial effect in the cardiovascular system. Therefore, the aim of this study was to estimate the effect of treatment with the DDP-4 inhibitor sitagliptin on SDF-1α levels in subjects with type 2 diabetes mellitus (T2D). Overall, 32 patients (16 males) with T2D, mean age (±SD) 67...

Age-related dementia is one of the most devastating disorders affecting the elderly. Recently, emerging data suggest that impaired insulin signaling is the major contributor in the development of Alzheimer's dementia (AD), which is the most common type of senile dementia. In the present study, we investigated the potential therapeutic effects of metformin (Met) and saxagliptin (Saxa), as insulin sensitizing agents, in a rat model of brain aging and AD using D-galactose (D-gal, 150 mg/kg/day, s.c. for 90 successive days)...

Advanced glycosylation end products (AGEs) formation is correlated with the pathogenesis of diabetic neuronal damage, but its links with oxidative stress are still not well understood. Metformin, one of the most widely used anti-diabetic drugs, exerts its effects in part by activation of AMP-activated protein kinase (AMPK). Once activated, AMPK regulates many pathways central to metabolism and energy balance including, glucose uptake, glycolysis and fatty acid oxidation. AMPK is also present in neurons, but its role remains unclear...

Cutaneous wounds are among the most common soft tissue injuries and are particularly hard to heal in aging. Caloric restriction (CR) is well documented to extend longevity; pharmacologically, profound rejuvenative effects of CR mimetics have been uncovered, especially metformin (MET), resveratrol (RSV), and rapamycin (RAPA). However, locally applied impacts and functional differences of these agents on wound healing remain to be established. Here, we discovered that chronic topical administration of MET and RSV, but not RAPA, accelerated wound healing with improved epidermis, hair follicles, and collagen deposition in young rodents, and MET exerted more profound effects...

The FATZO/Pco mouse is the result of a cross of the C57BL/6J and AKR/J strains. The crossing of these two strains and the selective inbreeding for obesity, insulin resistance and hyperglycemia has resulted in an inbred strain exhibiting obesity in the presumed presence of an intact leptin pathway. Routinely used rodent models for obesity and diabetes research have a monogenic defect in leptin signaling that initiates obesity. Given that obesity and its sequelae in humans are polygenic in nature and not associated with leptin signaling defects, the FATZO mouse may represent a more translatable rodent model for study of obesity and its associated metabolic disturbances...
