AB  - Although initially recognized as a universally beneficial approach for the prevention of age-related impairments, the outcome of calorie restriction (CR) is now known to depend on several factors, most notably the age of the subject at the CR commencement, and CR duration. We aimed to examine if and how CR affects anxiety-like behaviour when it is introduced at middle age and late middle age. In addition, as the dopaminergic system is one of the main neurotransmitter systems involved in controlling anxiety, we examined the expression of dopamine receptors (D1R, D2R) in the cortex, striatum, and mesencephalon of male Wistar rats of varying ages. The study was performed on rats fed ad libitum (AL) or exposed to calorie restriction (60% of AL intake). Open field and light-dark tests were used to study anxiety-like behaviour, while PCR and Western blot were used to examine the expression of dopamine receptors. Calorie restriction implemented at middle-age led to variable outcomes on anxiety-like behaviour, while CR implemented at late middle age increased anxiety and decreased the availability of D2R levels in the cortex and mesencephalon. Taken together, these results advise caution when implementing calorie restriction late in life. © 2022

AB  - Striving for longevity is neither a recent human desire nor a novel scientific field. The first article on this topic was published in 1838, when the average human life expectancy was approximately 40 years. Although nowadays people on average live almost as twice as long, we still (and perhaps more than ever) look for new ways to extend our lifespan. During this seemingly endless journey of discovering efficient methods to prolong life, humans were enthusiastic regarding several approaches, one of which is caloric restriction (CR). Where does CR, initially considered universally beneficial for extending both lifespan and health span, stand today? Does a lifelong decrease in food consumption represent one of the secrets of centenarians' long and healthy life? Do we still believe that if we eat less, we will live longer? This review aims to summarize the current literature on CR as a potential life-prolonging intervention in humans and discusses metabolic pathways that underlie this effect.

AB  - The current study aims to determine the potential benefits of calorie restriction (CR), one of the most promising paradigms for life span and healthspan extension, on cognitive performances in female Wistar rats during aging. As a measure of a healthspan, we evaluated the effects of different onset and duration of CR on frailty level. Female Wistar rats were exposed to either ad libitum (AL) or CR (60% of AL daily intake) food intake during aging. Two different CR protocols were used, life-long CR with an early-onset that started at the adult stage (6 months) and 3-month-long CR, started at the middle (15 months) and late-middle (21 months) age, thus defined as a late-onset CR. The effects of CR were evaluated using open-field, Y-maze, and novel object recognition tests. We broadened 2 tools for frailty assessment currently in use for experimental animals, and in alignment with our previous study, we created a physical-cognitive frailty tool that combines both physical and cognitive performances. Our results clearly showed that CR effects are highly dependent on CR duration and onset. While a life-long restriction with an early-onset has been proven as protective and beneficial, short-term restriction introduced at late age significantly worsens an animal's behavior and frailty. These results complement our previous study conducted in males and contribute to the understanding of sex differences in a response to CR during aging.

AB  - Non-diabetic and alloxan-induced diabetic rats were fed with standard laboratory food enriched with 20% virgin coconut oil for 16 weeks. In non-diabetic animals coconut oil improved insulin sensitivity and ability to control glycaemia and decreased the serum triglycerides for almost 50% in comparison with controls. Supplementation with coconut oil caused liver steatosis in both non-diabetic and diabetic animals. However, the severity of steatosis was lower in diabetic animals compared to non-diabetic animals. Coconut oil had no effects on heart histology, ascending and abdominal aorta wall thickening and atherosclerotic plaques development neither in non-diabetic nor in diabetic animals. While alloxan treatment caused Type I diabetes in rats, supplementation with coconut oil in combination with the alloxan unexpectedly resulted in Type II diabetes. The development of severe insulin resistance and deterioration in serum lipid profile implied that the use of coconut oil is contraindicated in diabetic condition.

Coconut oil had no effects on heart histology, ascending and abdominal aorta wall thickening and atherosclerotic plaques development neither in non-diabetic nor in diabetic animals. While alloxan treatment caused Type I diabetes in rats, supplementation with coconut oil in combination with the alloxan unexpectedly resulted in Type II diabetes. The development of severe insulin resistance and deterioration in serum lipid profile implied that the use of coconut oil is contraindicated in diabetic condition.",

AB  - Acute renal ischemia/reperfusion (I/R) is a temporary restriction of kidney blood supply, followed by blood flow restoration and re-oxygenation. During I/R, decreased oxygen supply disturbs ion transport, intracellular ATP, calcium and pH levels, and numerous signalling pathways. Upon reperfusion, a restoration of oxygen level rises a reactive oxygen species generation, cytokines and chemokines release from activated tissue-resident macrophages, and infiltration of pro-inflammatory neutrophils into ischemic tissues. All these changes result in cell swelling and rupturing, and consequent necrotic or apoptotic cell death. Meldonium is an anti-ischemic drug clinically used to treat myocardial and cerebral ischemia, which acts by shifting energy production from fatty acid oxidation to glycolysis. We investigated the effects of a 4-week meldonium pre-treatment with 300 mg/kg b.m./day of rats subjected to a well-established experimental model of renal I/R, with ischemia lasting for 45 minutes, followed by 4 hours of reperfusion. The degree of apoptosis and necrosis was evaluated by measuring renal pro-apoptotic Bax and anti-apoptotic Bcl-2 ratio, serum and kidney levels of necrotic marker - high mobility group box 1 protein (HMGB1), together with the kidney histology analysis. Our results showed that apoptotic and necrotic cell death occur simultaneously under I/R conditions, judging by the renal Bax/Bcl2 ratio rise (2.7-fold), increase in serum (22%) and renal (30%) levels of HMGB1, as well as severe tubular necrosis with dilatation of the tubular structure, cast formation, tubular lumina dilatation, brush border reduction, and loss in some renal areas cells. Meldonium pretreatment reduced the elevated Bax/Bcl2 ratio by 35%, as well as the serum and renal HMGB1 levels by 20% and notably diminished histological evidence of renal I/R necrotic injury, especially regarding tubular structures. These findings proved that meldonium protects renal cells against I/R-induced necrosis and apoptosis.

AB  - It is well known that stress changes levels of pituitary hormones in the bloodstream and in the pituitary itself. However, almost nothing is known about the impact of stress on histological and stereological parameters of the growth hormone producing cells (somatotrophs-GH cells). The aim of the present study was to investigate the effect of: acute and repeated immobilization; acute and repeated restraint on histological and morphofunctional parameters of somatotrophs in adult Wistar rats. Changes in the pituitary gland volume; the volume density and volume of somatotrophs following acute and repeated immobilization (IMO, R-IMO); acute and repeated restraint (R, R-R) were evaluated using a stereological system (newCAST), while growth hormone level within pituitary was determined by Western blot. Our results demonstrated the decrease (p < 0.05) of the pituitary volume (17%, 19%) in the IMO and R groups, respectively, and the increase in the R-R group. The volume density of GH cells decreased (p < 0.05) in the R-IMO (7%), R (26%) and R-R (18%) group in comparison to the control value. The pituitary GH content was increased (p < 0.05) after the IMO (2-fold), R (2.5-fold) and R-R (2.1-fold) as compared to the control group. These results point out that acute and repeated immobilization and/or restraint lead not only to changes in GH hormone concentration, but also modify the morphological aspects of GH cells within the rat pituitary.

AB  - We investigated the effect of long-term high-dose virgin coconut oil (VCO) supplementation on rat liver and serum lipid status. Animals were divided into two groups with 8 of them in each: normally fed (Control group) and the group fed with coconut oil at a concentration of 20% in food (VCO group). The experiment lasted for four months. On the last day of the experiment animals were killed, and blood and liver tissue were collected. In serum we measured the levels of total cholesterol (TC), high-density lipoproteins (HDL), non-HDL lipoproteins, triglycerides (TG), aspartate aminotransferase (9\.ST), alanine aminotransferase (ALT), and alkaline phosphatase (ALP). We also measured both liver and serum levels of high mobility group protein B 1 (HMGB 1) and haptoglobin (HP), as ,.vell as the liver level of NF-KB p65/ p-NF-KB p65 transcription factor, together with the histopathology analysis on liver slices and liver Comet assay. The results show that coconut oil do not change serum TC and HDL, but reduces non-HDL and TG levels (10% and 50%, respectively) comparing to control. As a result, atherogenic index of serum (AI) is strongly reduced in VCO group versus control. As for the liver status, results show that coconut supplementation increases AST, ALT and ALP levels in VCO group (50%, 30% and 60%, respectively) comparing to control. This effect is caused by the accumulation of coconut oil fat in liver, as confirmed by the histopathology showing signs of mild nonalcoholic steatohepatitis in VCO group, followed with the increased %of DNA in comet tail. The liver inflammation in VCO group is further demonstrated with the liver HP, HMGBl and p-NF-KB p65 level increase, and increase in nuclear level ofNF­kB p65, but not accompanying serum HP and HMGBl increase. In conclusion, our results show that coconut oil supplementation, despite causing mild and localized steatohepatitis, also lowers serum atherogcnic index, a predictor of cardiovascular risk.

AB  - We investigated the effect of long-term high-dose virgin coconut oil (VCO) supplementation on rat glucose homeostasis. Animals were divided into two groups with 6 of them in each: normally fed (Control group) and the group fed with coconut oil at a concentration of 20% in food (VCO group). The experiment lasted for four months. We measured fasting glycemia once a week during the entire experiment. In the last week of the experiment, we performed an oral glucose tolerance test (OGTT) and an intraperitoneal insulin tolerance test (ITT). On the last day of the experiment the fasting insulin and glyc8mia were measured in the blood of animals. The results show that coconut oil reduces weekly glycemia in VCO animals compared with controls. This effect reaches its maximum after the first two weeks of the experiment, and then slowly decreases and disappears over time of next eight weeks. As a result, the glycemia of control and VCO animals do not differ in last six weeks of the experiment. The area under the curve (AUC) presenting glycemia during whole the experiment is significantly lower in VCO animals than in the controls. The hypoglycemic effect of coconut oil is obviously dose-dependent since the amount of food (and therefore the coconut oil) that the animals eat decreases over the time. The results of the oral glucose tolerance test show that the OGTT AUC of VCO animals is significantly lower than the controls, and same is true for the insulin tolerance test. Finally, glycemia and insulin concentration in serums sampled on the last day of the experiment do not differ between VCO and Control groups, so accordingly neither HOMA-IR I and 2 (Homeostatic model assessment of insulin resistance) nor QUIC.Kl ( Quantitative Insulin Sensitivity Check Index). In conclusion, our results show beneficial effects of long-term high-dose coconut oil supplementation on rat glucose homeostasis.
