Dietary fiber and resistant starch are known to be beneficial in lowering both glucose and lipid concentration in human. Fibercreme, a fiber rich product has been developed. It is a commercial non-dairy creamer that uses various oligosaccharides such as Isomaltose-oligosaccharides (IMO) or inulin as fiber source to replace the glucose component of conventional creamer. In this study, IMO and fibercreme were used to replace sucrose of the banana porridge. Therefore, the purpose of this study was to determine porridge effects on glucose, triglyceride, serum cholesterol and digesta profile in diabetic STZ-NA induced rats. Twenty-five male Wistar rats were divided into five groups and fed four different diets including the standard (KS and KN), banana porridge with sweetener IMO (BP+IMO), fibercreme (BP+FC) and (BP + Sukrosa). In these diets, porridge subtituted 30% energy of the standard diet, and the intervention was conducted for 28 days. It was found that banana-IMO porridge showed the lowest decrease in serum glucose level with 56.09%, followed by banana-fibercreme (47.61%) and bananasucrose (36.61%). Furthermore, similar trend was found in their cholesterol-lowering effects with 36.82%, 25.68% and 7.86% respectively. However, triglyceride level effects were highest in banana-IMO porridge (9.06%), followed by banana-sucrose (6.47%) and banana-fibercreme (3.72%). In addition, sucrose replacement with IMO increases weight and water content, as well as decrease caecal digesta pH. However, fibercreme increases only water content and does not decrease caecal digesta pH.

Progressive Renal Insufficiency

Under experimental conditions severe reduction of renal mass results in the hyperfiltration of the remaining nephrons leading to a progressive renal insufficiency. Similar changes are observed in patients with various renal disorders associated with a loss of the functioning nephrons. The progression of renal damage is accelerated by high protein and phosphate intake, and may be modified by the dietary restrictions.We studied 50 five-sixth nephrectarrized male Wistar rats on a standard diet (Rodent Laboratory Chow 5001 Ralston Purina Co., Richmond, Indiana; containing 23.4% protein) over a 20 week period.

Choline (Ch) is an essential molecule of substantial importance for the optimal development and function of several biological systems. Ch deprivation has been linked with abnormal fat metabolism, insulin resistance, and myocardial dysfunction. The current study provides evidence of an exacerbation of streptozotocin-induced cardiomyopathy in adult diabetic Wistar rats by dietary Ch deprivation through the administration of a Ch-deprived diet (CDD). Twenty-four adult male Wistar rats were randomly separated into four groups: control, diabetic (DM), choline-deprived through choline-deprived diet (CD), and diabetic choline-deprived (DM + CD). After five weeks of dietary intervention, myocardium echocardiographic and histological assessments were performed. Choline-deprived diabetic rats exhibited significantly slower heart rate, significantly higher myocardial ejection velocity and left ventricle wall tension index with a concomitant significant decreased LV posterior wall thickness as compared to diabetic rats fed on a standard diet. Moreover, histopathological evidence demonstrated an exacerbation of myocardial inflammation and fibrosis associated with significant up-regulation of VEGF expression in the diabetic rat myocardium as a result of Ch deprivation. The study’s findings are of particular significance since the examined experimental approach introduces a previously uncharacterised comorbidity simulation with regards to myocardial structure and functional profiling.

The aim of this study was to examine the effects of a methionine-enriched diet on anxiety-related behavior in rats and to determine the role of the brain oxidative status in these alterations. Adult male Wistar rats were fed from the 30th to 60th postnatal day with standard or methionine-enriched diet (double content comparing with standard diet: 7.7 g/kg). Rats were tested in open field and light–dark tests and afterwards oxidative status in the different brain regions were determined. Hyperhomocysteinemia induced by methionine-enriched diet in this study decreased the number of rearings, as well as the time that these animals spent in the center of the open field, but increased index of thigmotaxy. Oxidative status was selectively altered in the examined regions. Lipid peroxidation was significantly increased in the cortex and nc. caudatus of rats developing hyperhomocysteinemia, but unaltered in the hippocampus and thalamus. Based on the results of this research, it could be concluded that hyperhomocysteinemia induced by methionine nutritional overload increased anxiety-related behavior in rats. These proanxiogenic effects could be, at least in part, a consequence of oxidative stress in the rat brain.

Abstract Objectives To evaluate the effect of consumption of yacon flour, kefir and the association between them on colon cancer induced by 1,2-dimethylhydrazine (DMH) in male Wistar rats, SCFA production, fecal pH and intestinal permeability. Methods The study was conducted with 60 adult Wistar rats divided into 5 groups. For 5 weeks, groups T, Y, K and YK received 1,2-dimethylhydrazine (DMH) to induce colon cancer. After 5 weeks of DMH administration, animals in groups C and T received the standard diet, group Y received a diet with yacon flour with 5% FOS, group K received 1mL /day of kefir and the YK group received a diet with yacon and kefir, for 15 weeks. After euthanasia, intestinal lesions, intraluminal pH, short-chain fatty acids (SCFA) and intestinal permeability were analyzed. Results An increase in macroscopic lesions was observed in groups K (58%) and YK (42%) and a reduction of 5% in group Y, compared to group T. In addition, an increase in neoplastic changes was observed in all groups compared to group T: Y (33%), K (67%) and YK (78%). There was no significant difference in the concentrations of acetate and proprionate, pH, lactulose and mannitol between groups, and butyrate was not found in the samples. Conclusions The consumption of yacon flour, kefir and their association did not influence intestinal physiology and promoted the worsening of the development of colon carcinogenesis in rats.

High-salt (HS) diets have recently been linked to oxidative stress in the brain, a fact that may be a precursor to behavioral changes, such as those involving anxiety-like behavior. However, to the best of our knowledge, no study has evaluated the amygdala redox status after consuming a HS diet in the pre- or postweaning periods. This study aimed to evaluate the amygdala redox status and anxiety-like behaviors in adulthood, after inclusion of HS diet in two periods: preconception, gestation, and lactation (preweaning); and only after weaning (postweaning). Initially, 18 females and 9 male Wistar rats received a standard (n = 9 females and 4 males) or a HS diet (n = 9 females and 5 males) for 120 days. After mating, females continued to receive the aforementioned diets during gestation and lactation. Weaning occurred at 21-day-old Wistar rats and the male offspring were subdivided: control-control (C-C)—offspring of standard diet fed dams who received a standard diet after weaning (n = 9–11), control-HS (C-HS)—offspring of standard diet fed dams who received a HS diet after weaning (n = 9–11), HS-C—offspring of HS diet fed dams who received a standard diet after weaning (n = 9–11), and HS-HS—offspring of HS diet fed dams who received a HS diet after weaning (n = 9–11). At adulthood, the male offspring performed the elevated plus maze and open field tests. At 152-day-old Wistar rats, the offspring were euthanized and the amygdala was removed for redox state analysis. The HS-HS group showed higher locomotion and rearing frequency in the open field test. These results indicate that this group developed hyperactivity. The C-HS group had a higher ratio of entries and time spent in the open arms of the elevated plus maze test in addition to a higher head-dipping frequency. These results suggest less anxiety-like behaviors. In the analysis of the redox state, less activity of antioxidant enzymes and higher levels of the thiobarbituric acid reactive substances (TBARS) in the amygdala were shown in the amygdala of animals that received a high-salt diet regardless of the period (pre- or postweaning). In conclusion, the high-salt diet promoted hyperactivity when administered in the pre- and postweaning periods. In animals that received only in the postweaning period, the addition of salt induced a reduction in anxiety-like behaviors. Also, regardless of the period, salt provided amygdala oxidative stress, which may be linked to the observed behaviors.

Chronic consumption of acetaminophen (APAP) during exercise training leads to a reduction in tendon stiffness and modulus compared with a placebo. We explored whether this effect could be due to a reduction in tendon collagen content or cross-linking. Ten-week-old male Wistar rats ( n = 50) were divided into placebo or APAP groups and into sedentary or treadmill-exercised groups. APAP (200 mg/kg) or saline was administered once daily by oral gavage. Rats in the exercise groups ran on a treadmill 5 days per week for 8 wk with progression to 60 min per day, 20 m/min, and 8° incline. After 8 wk, lyophilized Achilles tendon samples were assayed for the collagen-specific amino acid hydroxyproline and cross-linking [hydroxylyslpyridinoline (HP)] content by high-performance liquid chromatrography. Collagen content was not influenced by exercise or APAP ( P > 0.05). Compared with placebo, tendon water content was 7% ( P = 0.006, main effect) lower in animals consuming APAP (placebo: 54.79 ± 0.8%, APAP: 50.89 ± 1.2%). HP in the Achilles tendon was 36% greater (sedentary: 141 ± 15, exercise: 204 ± 26 mmol/mol collagen) in the exercise-trained rats independent of drug treatment ( P = 0.020, main effect). Independent of exercise, HP content was 33% lower ( P = 0.032, main effect) in the animals consuming APAP (placebo: 195 ± 21, APAP: 140 ± 19 mmol/mol collagen). Our data suggests that chronic consumption of APAP results in a reduction in collagen cross-linking and a loss of tissue water independent of chronic exercise. This reduction in cross-linking and water content could contribute to the decrease in tendon stiffness noted in humans chronically consuming APAP.

High saturated fat diets have been associated with the development of obesity and hypertension, along with other pathologies related to the metabolic syndrome. In contrast, the Mediterranean diet, characterized by its high content of monounsaturated fatty acids, has been proposed as a dietary factor capable of positively regulating cardiovascular function. These effects have been linked to changes in the local renal renin angiotensin system (RAS) and the activity of the sympathetic nervous system. The main goal of this study was to analyze the role of two dietary fat sources on aminopeptidases activities involved in local kidney RAS. Male Wistar rats (six months old) were fed during 24 weeks with three different diets: the standard diet (S), the standard diet supplemented with virgin olive oil (20%) (VOO), or the standard diet enriched with butter (20%) plus cholesterol (0.1%) (Bch). Kidney samples were separated in medulla and cortex for aminopeptidase activities (AP) assay. Urine samples were collected for routine analysis by chemical tests. Aminopeptidase activities were determined by fluorometric methods in soluble (sol) and membrane-bound (mb) fractions of renal tissue, using arylamide derivatives as substrates. After the experimental period, the systolic blood pressure (SBP) values were similar in standard and VOO animals, and significantly lower than in the Bch group. At the same time, a significant increase in GluAP and IRAP activities were found in renal medulla of Bch animals. However, in VOO group the increase of GluAP activity in renal medulla was lower, while AspAP activity decreased in the renal cortex. Furthermore, the VOO diet also affected other aminopeptidase activities, such as TyrAP and pGluAP, related to the regulation of the sympathetic nervous system and the metabolic rate. These results support the beneficial effect of VOO in the regulation of SBP through changes in local AP activities of the kidney.

The aim of the present study evaluated the influence of oil or flaxseed flour in pancreas morphology of pups, whose mothers were fed with oil or flaxseed flour during lactation, at weaning. After birth, the lactating rat males were randomly assigned: control (C, n=12 pups), flaxseed oil (FO, n=12 pups) and flaxseed flour (FF, n=12). At 21 days, the pups were weaning and anesthetized. Body mass, length, serum glucose, insulin, pancreas mass and pancreatic islet area were assessed. FO and FF showed higher (p<0.05) mass and length and lower glucose (p<0.05) when compared with C. Insulin (p=0.094) and pancreas mass (p=0.054) not differ between groups. FO and FF showed lower (p<0.05) pancreatic islet area when compared with C. A fed with FO or FF, during lactation may improve function pancreatic, as insulin sensitivity. These findings emphasize that oil or flaxseed flour during lactation may improve pancreatic function in early life.
