Advancing age is one of the risk factors for developing many diseases, including cancer, cardiovascular disorders, and neurodegenerative alterations, such as mild cognitive impairment (MCI), and Alzheimer's Disease (AD). Studies have indicated that supplementation with resveratrol (RSV) might improve cerebrovascular function and reduce the risk of developing dementia. Thus, the aim of this systematic review was to assess the effects of RSV on MCI and AD. MEDLINE-PubMed, Cochrane, and EMBASE were used to perform the search, and PRISMA guidelines were followed. Five studies met the eligible criteria; three with AD and two with MCI. In AD patients, the use of RSV reduces Aβ levels, improves brain volume, reduces the Mini-mental status score, and improves AD scores. In patients with MCI, this polyphenol prevents decline in Standard Volumes of Interest and increases the Resting-state Functional Connectivity score. RSV can activate the human silent information regulator 2/sirtuin 1 (Sirt-1) and can inhibit the cyclooxygenase-2 (COX-2), 5-lipoxygenase, and nuclear factor-κB, resulting in the reduction of the proinflammation pathways. It is also associated with the increase in the levels of interleukin (IL)-10 and reduction of interferon-γ and IL-17. Both anti-inflammatory and antioxidant effects can be related to preventing neurodegenerative diseases, doing maintenance, and enabling the recovery of these conditions directly related to inflammation and oxidative stress. We suggest that the use of RSV can bring beneficial effects to patients with MCI or AD.

Manilkara zapota is a tropical evergreen tree belonging to the Sapotaceae family; its parts are used in alternative medicine to treat coughs and colds and possess diuretic, antidiarrheal, antibiotic, antihyperglycemic, and hypocholesterolemic effects. There are no studies on metabolic profile after using the fruit, and this study aimed at evaluating the effects of the leaf and pulp of M. zapota fruit on the metabolic profile of Wistar rats. Male rats were treated for 50 days with M. zapota leaf juice or fruit juice, after which their biochemical and body composition profiles were analyzed (glycemia, triglycerides, high-density lipoprotein cholesterol (HDL-c), insulin, leptin, aspartate transaminase, alanine aminotransferase, Lee Index, and body mass index). Our results indicate significantly lower levels of glycemia, insulin, leptin, cholesterol, and triglycerides and augmented levels of HDL-c in animals treated with the leaves or fruit of this plant. The percentage of weight gain also declined in animals treated with M. zapota fruit pulp. The use of the M. zapota may be helpful in the prevention of obesity, diabetes, dyslipidemia, and their complications.

Dry extract of the genus Passiflora has been shown to help control glycemia and lipid levels. The objective of this study was to evaluate the effects of passion fruit (P. edulis) on the biochemical profile of offspring from diabetic rats. Diabetes was induced by streptozotocin. The diabetes group consisted of 10 rats with glucose levels greater than 200 mg/dL;the nondiabetic (control) group consisted of 10 rats with glucose levels less than 120 mg/dL. After the diagnosis of diabetes,the mating phase was started. By day 21 of pregnancy, the offspring were born; the dams were kept in individual cages with their offspring until the weaning period. The offspring were then divided into 4 groups (n = 15 each): G1 were offspring from control dams, G2 were offspring from treated nondiabetic dams, G3 were offspring from diabetic dams, and G4 were offspring from treated diabetic dams. For 30 consecutive days, G1 and G3 offspring were treated with vehicle (oral gavage) and G2 and G4 offspring were treated with passion fruit juice (oral gavage). After 30-day treatment, the animals were anesthetized and killed, and blood was drawn immediately for analysis of the biochemical profile (total cholesterol, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, triglycerides, and glucose). The G2 and G4 rats showed significantly reduced total cholesterol, triglyceride, and low-density lipoprotein cholesterol levels and an increased high-density lipoprotein cholesterol level. The use of passion fruit juice improved lipid profiles, suggesting that this plant may have beneficial effects in the prevention and treatment of dyslipidemias and hyperglycemia.

Adaptogen-based plant formulations play an important role in traditional medicine and have been used in medical practice to increase the resistance of individuals. Rhodiola rosea (RR) and Panax ginseng (PG) exhibit adaptogenic properties and are related to the recovery of homeostasis and strengthen systems impaired by stress. This study aimed to evaluate the effects of RR and PG on metabolic profile and muscle damage parameters in Wistar rats submitted to swimming. Animals were divided according to the following: G1: control group; G2: group that was submitted to swimming; G3: group treated with PG; G4: group treated with PG and submitted to swimming; G5: treated with RR; and G6: treated with RR and submitted to swimming. At the end of the experimental protocol, groups G2, G4, and G6 practiced swimming for a period five times longer than during the previous 30 days. Anthropometric and biochemical parameters were investigated, and no significant results were found in the groups. Nevertheless, animals treated with PG and RR reduced the levels of creatine phosphokinase (CPK) and lactic dehydrogenase (LDH). Our findings demonstrate that both PG and RR produced a significant reduction in the levels of CPK and LDH after physical stress, suggesting that they can be used to improve physical performance. For these reasons, we may say that these plants may be used to minimize the stress promoted by the practice of physical exercises.

Annona montana Fruit and Leaves Improve the Glycemic and Lipid Profiles of Wistar Rats

Species of the family Annonaceae has been used traditionally as a medicinal plant in tropical regions of South and North America and in Africa. Annona montana is known popularly as false graviola and originates from tropical America and can be cultivated throughout Brazil. There are no studies in the literature that associate A. montana with the metabolic profile of animals. Therefore, the purpose of this work was to assess the effects of the consumption of pulp and leaves of this plant on the metabolic profile of Wistar rats. The animals, which were treated for 40 days, were divided into two control groups—treated with water via gavage and ad libitum, respectively, and two treated groups—one treated with leaf juice and the other with pulp juice of the fruit. Glycemia, lipids, and body weight were found to decrease and high density lipoprotein-cholesterol (HDL-c) levels to increase in the animals treated with leaf juice. The group treated with pulp juice showed a reduction in lipids and augmented HDL-c. The use of A. montana may have beneficial effects in the prevention of diabetes mellitus and dyslipidemia and may thus contribute to the prevention of cardiovascular diseases.
