RESUMEN
Maternal obesity is the key predictor for childhood obesity and neurodevelopmental delay in the offspring. Medicinal plants are considered to be the safe and best option, and at the same time, probiotic consumption during pregnancy provides beneficial effects for both the mother and the child. Current research has shown that Elateriospermum tapos (E. tapos) yoghurt is safe to consume and consists of many bioactive compounds that can exert an anti-obesity effect. Thus, this study has been designed to study the role of E. tapos yoghurt in mitigating maternal obesity. In this study, a total of 48 female Sprague Dawley (SD) rats were assigned to six groups, with eight rats per group, and obesity was induced over 16 weeks with a high-fat diet (HFD) pellet. On the 17th week, the rats were allowed to mate and pregnancy was confirmed through vaginal smear. The obese induced group was further divided into negative and positive control groups, followed by E. tapos yoghurt treatment groups with three different concentrations (5, 50, and 500 mg/kg). The changes in body weight, calorie intake, lipid profile, liver profile, renal profile, and histopathological analysis were measured on postnatal day (PND) 21. The results show that the group with the highest concentration of E. tapos yoghurt (HYT500) supplementation shows gradual reduction in body weight and calorie intake on PND 21 and modulates the lipid level, liver, and renal enzymes to a normal level similar to the normal group. In histological analysis, HYT500 reverses the damage caused by HFD in liver and colon, and reverses the adipocytes' hypertrophy in retroperitoneal white adipose tissue and visceral fat. In conclusion, supplementation of E. tapos yoghurt during the gestational period up to weaning is effective in the gradual weight loss of maternal obese dams from the 500-mg/kg-supplemented group in this study.

Maternal obesity is a key predictor of childhood obesity and a determining factor for a child's body composition. Thus, any form of maternal nutrition during the gestational period plays a vital role in influencing the growth of the fetus. Elateriospermum tapos (E. tapos) yogurt has been found to comprise many bioactive compounds such as tannins, saponins, α-linolenic acid, and 5'-methoxy-bilobate with apocynoside I that could cross the placenta and exhibit an anti-obesity effect. As such, this study aimed to investigate the role of maternal E. tapos yogurt supplementation on offspring body composition. In this study, 48 female Sprague Dawley (SD) rats were induced with obesity using a high-fat diet (HFD) and were allowed to breed. Upon confirmation of pregnancy, treatment was initiated with E. tapos yogurt on the obese dams up to postnatal day 21. The weaning offspring were then designated into six groups according to their dam's group (n = 8) as follows; normal food and saline (NS), HFD and saline (HS), HFD and yogurt (HY), HFD and 5 mg/kg of E. tapos yogurt (HYT5), HFD and 50 mg/kg of E. tapos yogurt (HYT50), and HFD and 500 mg/kg of E. tapos yogurt (HYT500). The body weight of the offspring was accessed every 3 days up to PND 21. All the offspring were euthanized on PND 21 for tissue harvesting and blood sample collection. The results showed that both male and female offspring of obese dams treated with E. tapos yogurt showed growth patterns similar to NS and reduced levels of triglycerides (TG), cholesterol, LDL, non-HDL, and leptin. Liver enzymes such as ALT, ALP, AST, GGT, and globulin, and renal markers such as sodium, potassium, chloride, urea, and creatinine levels significantly reduced (p < 0.05) in the offspring of E. tapos yogurt-treated obese dams with the normal histological architecture of the liver, kidney, colon, RpWAT, and visceral tissue that is comparable to NS. In toto, E. tapos yogurt supplementation of obese dams exerted an anti-obesity effect by preventing intergenerational obesity by reversing HFD-induced damage in the fat tissue of the offspring.

The Bouea macrophylla fruit is native to Malaysia and is known for its many beneficial effects on one's health. Probiotics are well-known for their roles as anti-inflammatory, antioxidant, and anti-tumour properties due to their widespread use. As a result, the purpose of this study was to incorporate the ethanolic extract of Bouea macrophylla into yoghurt and then assess the rodents for any toxicological effects. According to the findings of the nutritional analysis, each 100 mL serving of the newly formulated yoghurt contains 3.29 g of fat, 5.79 g of carbohydrates, 2.92 g of total protein, and 2.72 g of sugar. The ability of the newly developed yoghurt to stimulate the growth of Lactobacilli was demonstrated by the fact that the peak intensity of Lactobacillus species was measured at 1.2 × 106 CFU/g while the titratable acidity of the lactic acid was measured at 0.599 CFU/g. In order to carry out the toxicological evaluation, forty-eight male Sprague Dawley (SD) rats were utilized. Oral administration of single doses of 2000 mg/kg over the course of 14 days was used for the study of acute toxicity. Subacute toxicity was studied by giving animals Bouea macrophylla yoghurt (BMY) at repeated doses of 50, 250, 500, and 1000 mg/kg/day over a period of 28 days, while the control group was given normal saline. The results of the acute toxicity test revealed that rats treated with increasing doses up to a maximum of 2000 mg/kg exhibited no signs of toxicity. After an additional 14 days without treatment, acute toxicity of a single dose (2000 mg/kg) of BMY did not show any treatment-related toxicity in any of the rats that were observed. According to the data from the subacute toxicity study, there were no differences between the treated groups and the control groups in terms of food and water intake, body weight, plasma biochemistry (AST, ALT, ALP, and creatinine), haematological products, or organ weights. The architecture of the liver, heart, and kidney were all found to be normal upon histological examination. This indicates that oral consumption of BMY did not result in any negative effects being manifested in the rodents.

OBJECTIVES: Pre-pregnancy obesity is a serious epidemics concern that negatively affects the neurodevelopmental of the offspring. Elateriospermum tapos (E. tapos) commonly used to enhance weight loss in obesity treatment. This study was aimed to investigate the influence of E. tapos supplement in obese maternal prior pregnancy on the offspring's bodyweight, lipid metabolism and memory function. METHODS: Thirty female Sprague Dawley rats were used. Six rats were assigned to the normal diet group (DND). The remaining rats were fed with a high-fat and cafeteria diet (HFCD) to generate obesity for 5 weeks. Obese rats were further divided into four groups: Negative Control (DNC; HFCD), Positive Control (DPC; Orlistat 200 mg/kg), treatment 1 (DTX1; E. tapos seed 200 mg/kg) and treatment 2 (DTX2, E. tapos shell 200 mg/kg) were given daily, for 6 weeks prior to mating. At weaning, offspring of both genders were designated into six groups according to their dam's group (n=6/group). All groups were fed with a cafeteria diet except for the control group. Memory tasks for object and place recognition were conducted on offspring at eighth weeks of age. The offspring were cull at the 12th week of age for their blood sample. RESULTS: Both offspring genders from DTX2 significantly reduce bodyweight, calorie intake and triglyceride level. In memory tasks, offspring from DTX2 showed a significant increase in exploration rate in place test as compared to offspring from the DNC group. CONCLUSIONS: This study highlights E. tapos shell as an anti-obesity agent and protecting memory deficit in obese dam's offspring.

The effects of palm gamma-tocotrienol (GGT) on oxidative stress-induced cellular ageing was investigated in normal human skin fibroblast cell lines derived from different age groups; young (21-year-old, YF), middle (40-year-old, MF) and old (68-year-old, OF). Fibroblast cells were treated with gamma-tocotrienol for 24 hours before or after incubation with IC50 dose of H2O2 for 2 hours. Changes in cell viability, telomere length and telomerase activity were assessed using the MTS assay (Promega, USA), Southern blot analysis and telomere repeat amplification protocol respectively. Results showed that treatment with different concentrations of gamma-tocotrienol increased fibroblasts viability with optimum dose of 80 microM for YF and 40 microM for both MF and OF. At higher concentrations, gamma-tocotrienol treatment caused marked decrease in cell viability with IC50 value of 200 microM (YF), 300 microM (MF) and 100 microM (OF). Exposure to H2O2 decreased cell viability in dose dependent manner, shortened telomere length and reduced telomerase activity in all age groups. The IC50 of H2O2 was found to be; YF (700 microM), MF (400 microM) and OF (100 microM). Results showed that viability increased significantly (p < 0.05) when cells were treated with 80 microM and 40 microM gamma-tocotrienol prior or after H2O2-induced oxidative stress in all age groups. In YF and OF, pretreatment with gamma-tocotrienol prevented shortening of telomere length and reduction in telomerase activity. In MF, telomerase activity increased while no changes in telomere length was observed. However, post-treatment of gamma-tocotrienol did not exert any significant effects on telomere length and telomerase activity. Thus, these data suggest that gamma-tocotrienol protects against oxidative stress-induced cellular ageing by modulating the telomere length possibly via telomerase.
