RESUMEN

Colorectal cancer (CRC) poses a significant global health burden, being the third most prevalent cancer and the second most significant contributor to cancer-related deaths worldwide. Preventive strategies are crucial to combat this rising incidence. 6-shogaol, derived from ginger, has shown promise in preventing and treating various cancers. This study investigated the preventive effects of 6-shogaol on azoxymethane (AOM) and dextran sulfate sodium (DSS)-induced CRC in mice. Forty male BALB/c mice were randomly divided into control, 6-shogaol, AOM + DSS, and 6-shogaol + AOM + DSS. Mice in the control group received corn oil for 16 weeks, while those in the 6-Shogaol group were administered 20 mg/kg of 6-shogaol for 16 weeks. The AOM + DSS group received a single intraperitoneal dose (ip) of 10 mg/kg of AOM, followed by three cycles of 2.5% DSS in drinking water. The 6-shogaol + AOM + DSS group received both 6-shogaol for 16 weeks and a single ip of 10 mg/kg of AOM, followed by three cycles of 2.5% DSS in drinking water. The AOM + DSS-treated mice exhibited reduced food consumption, colon weight, and colon length, along with increased tumor formation. Co-administration of 6-shogaol effectively reversed these changes, inhibiting CRC development. Histopathological analysis revealed protective effects of 6-shogaol against colonic insults and modulation of inflammatory responses. 6-shogaol significantly reduced Carcinoembryonic antigen and Kiel 67 levels, indicating inhibition of tumor cell proliferation. Mechanistically, 6-shogaol promoted apoptosis by upregulating protein 53 and caspase-3 expression, and it effectively restored the balance of the Wingless-related integration site signaling pathway by regulating ß-catenin and adenomatous polyposis coli levels. Moreover, 6-shogaol demonstrated anti-inflammatory effects, reducing myeloperoxidase, Tumor necrosis factor alpha, and cyclooxygenase-2 levels in AOM/DSS-treated mice. Additionally, 6-shogaol restored redox homeostasis by reducing lipid peroxidation and nitrosative stress and enhancing antioxidant enzyme activities. The findings suggest that 6-shogaol inhibits cell proliferation, induces apoptosis, regulates Wnt signaling, suppresses inflammation, and restores redox homeostasis, providing comprehensive insights into its potential therapeutic benefits for CRC.

RESUMEN

Most teenagers mix up various psychoactive cocktail substances in combinations to get intoxicated. The role of the mixture combination of codeine (CDE), tramadol (TMD), and Cannabis sativa (CNB) on brain cognition, purinergic, cholinergic, and antioxidant enzyme activities remains unknown. This study sought to assess the mechanism of action of combinations of CDE+ TMD+ CNB on the function and activities of the brain of male Wistar rats. Forty-eight male Wistar rats were divided into 8 groups, n = 6. Group 1 served as a control, groups 2, 3, and 4 were exposed to CDE (2 mg/kg bw), TMD (10 mg/kg bw), and CNB (200 mg/kg bw), while groups 5, 6, 7, and 8 were co-administered with CDE+TMD, CNB+ TMD, CNB+CDE, and CNB+TMD+CDE orally for 28 days. This study revealed the effect of prolonged administration of CNB, TMD, and CDE on the suppression of cognitive function, acetyl-cholinesterase (AChE), butyl-cholinesterase (BChE), monoamine oxidase (MAO) enzyme activities, and antioxidant enzyme activities in rats' brains when compared against control rats (P < 0.05). However, the activities of ectonucleosides (NTPdase), adenosine deaminase (ADA), and malondialdehyde levels produced in the brain of rats were significantly elevated (P < 0.05). This study reported the mechanism behind the neurotoxicity of CNB, TMD, and CDE on rats' cognitive, cholinergic, purinergic, and antioxidant enzymes as a consequence of the drastic reduction in cholinesterase enzyme activities leading to neurotransmitter poisoning.

RESUMEN

Colorectal adenoma appears as benign lesions and is a precursor of colorectal adenocarcinoma. The effect of 6-Shogaol (6-[S]), a bioactive agent from ginger, in early colonic adenoma growth is unknown. As a result, this study examines the effect of 6-[S] in a mouse colorectal adenoma model induced by Azoxymethane (AOM) and dextran sulfate sodium (DSS). Adult male mice served as control in Group 1. Group 2 was treated orally with 6-[S] extract (20 mg/kg BW). Group 3 was exposed to AOM (25 mg/kg BW, ip) and one cycle of DSS (2.5%) in drinking water alone while Group 4 was co-treated with 6-[S] for twenty-one (21) days. The body weight gain, organ weight and length, oxidative stress indices, inflammatory markers and histological examination were estimated. Our findings show that 6-[S] co-treatment reversed AOM/DSS-induced elevation in colon weight, colon length, nitric oxide (NO), myeloperoxidase (MPO), hydrogen peroxidase (H2 O2 ), and tumor necrosis factor-alpha (TNF-α). However, the antioxidant enzyme activities measured namely catalase (CAT), superoxide dismutase (SOD), reduced glutathione (GSH), and glutathione-S-transferase were significantly increased in 6-[S] treated mice. Taken together, the protective effect of 6-[S] on oxidative burden, inflammation, and histological aberration observed in the colon of the AOM/DSS model of adenoma growth in mice is mediated primarily owing to its anti-inflammatory and anti-oxidative properties. Thus, this study reveals 6-[S] as a useful agent in the possible clinical intervention of colorectal adenoma. PRACTICAL APPLICATIONS: Certain spices have been reported to have numerous phytochemicals with numerous medicinal purposes. However, no studies have been conducted to investigate the role of 6-[S], a phytochemical found in ginger, in the treatment of colorectal adenoma. The study's findings show that 6-[S] is protective in early colonic cancer development, as it manages colorectal adenoma cancer models of AOM/DSS. As a result, 6-[S]'s ability to reduce oxidative stress and inflammation in the colon may be a potential nutritional therapeutic adjuvant for colorectal adenoma.

RESUMEN

This study analyzed the effects of functional cereals processed and produced from yellow corn, soybean, acha, orange peels and moringa leaves' polyphenolic content, glycemic index, starch composition and their effects on α-amylase and α-glucosidase enzymes in vitro. Functional cereals were produced as ready-to-eat cereals at different proportion with variations in the amount of measured acha flour, soybean flour, and blends of orange peels and moringa leaves while maintaining a constant amount of yellow corn. The produced orange peels and moringa leaves blends inclusion to functional cereals had significantly increased phenolic constituents, showed inhibitory activity on α-amylase and α-glucosidase enzymes in-vitro and reduced glycemic index, starch content and starch to sugar ratios. Interestingly, amongst the produced functional cereals, the best two cereals were with their composition made up of corn, acha, soybean, orange peel, moringa leaves (30: 5:15: 0.5: 0.5) and corn, acha, soybean, moringa leaves (30: 5: 15: 1) which both had the high inhibitory effects on the activities of α-amylase and α-glucosidase while depleting starch content in-vitro when compared with commercially consumed cereals (golden morn). PRACTICAL APPLICATIONS: Ready-to-eat cereals are highly consumed by children and by adults inclusively. Commercial breakfast cereals are readily available and consumed irrespective of the fact it has high calorie constituent as more emphasis is placed on their nutrients value which includes vitamins A, vitamin C and calcium for boosting immune system and for proper body growth and functioning. However, these commercial breakfast cereals (golden morn) owing to the high maize and millet content present in them are unfavorable to certain consumers or individuals with health challenges such as diabetic patients. This study shows that functional cereals produced in-vitro extensively are not only nutritious but also medicinal in nature, offering benefits in the management of diabetes and related complications.

RESUMEN

The broad application of Moringa oleifera leaves in the treatment of numerous diseases is prevalent globally where it extends to the management of diabetes, hypertension, inflammation, hypercholesterolemia and neurodegenerative diseases. This study provides findings on the role of Moringa oleifera leaves (MO) [MO leaves] formulated ice creams on brain cholinergic enzymes [acetylcholinesterase (AChE) and butyrylcholinesterase (BChE)], antioxidant enzymes, glycemic index and blood lipid profile of rats. Thirty (30) adult male rats acclimatized for 2 weeks were divided into five groups: Group 1 rats received commercial ice cream, Group 2 rats were received plain ice-cream, Group 3, 4 and 5 received 0.5 g, 1.0 g and 2.0 g of MO-formulated ice creams. Rats were fed on normal pellets and exposed to ice creams produced from whipping cream, skimmed milk and Moringa oleifera leaves for 30 consecutive days. Following administration, results from this study revealed that rats that received Moringa formulated ice-creams had reduced brain butyrylcholinesterase (BChE) and acetylcholinesterase (AChE) enzymes activities, glycemic index (GI), total cholesterol (TC), triglycerides (TG) and low-density lipoprotein cholesterol (LDL-C) levels and significantly increased high-density lipoprotein-cholesterol (HDL-C) level in the plasma while revealing elevated brain antioxidant status (Superoxide dismutase (SOD) and Catalase (CAT)) when compared against rats consuming commercial ice creams. Therefore, results from this study attests to the intake of ice creams made from blends of Moringa leaves in the reduction of rats' body weight, glycemic index and lipid profile (TC, TG, LDL-C), inhibition of brain cholinergic enzymes (AChE and BChE) while increasing brain antioxidant enzymes activities (SOD and CAT).

RESUMEN

The use of lemon (Citrus limon) and lime (Citrus aurantifolia) juices for the treatment of erectile dysfunction (ED) is fast becoming common practice, even though there is dearth of information on the effect of such functional food and drug combination in the management of ED. This study evaluated the effect of lemon and lime juices on the erectogenic properties of sildenafil. ED was induced with L-NAME (40 mg/kg body weight). The rats were divided into 11 groups (n = 6) and given various doses of the test samples. Immediately after the sexual behavior studies, the animals were sacrificed and the penile and brain tissues were isolated. The results revealed that lime and lemon juices improved sexual behavior in rats by improving NO production and inhibiting the activities of PDE-5, arginase, ACE, MAO, ATPdase, AMPdase, and activated antioxidant enzymes. Furthermore, lime at 1.0 ml/kg significantly improved the therapeutic properties of sildenafil. While, lemon (0.5 and 1.0 ml/kg) and lime (0.5 ml/kg) did not show any synergistic effect. This study revealed that lime and lemon juices could improve erectile function and combining lime juice with sildenafil could be very effective in the management of ED. PRACTICAL APPLICATIONS: The therapeutic management of erectile dysfunction has involved maximizing NO production through the modulation of macromolecules such as phosphodiesterase-5 and arginase with the use of drugs such as sildenafil. Combining such drugs with functional foods such as lime and lemon juices is becoming common practice. However, there is dearth of report on the effect of lime and lemon juices on the erectogenic potentials of sildenafil. The present study shows that combining 1 ml/kg lime juice (got from 2 lime fruits) with sildenafil will boost the erectogenic properties of the drug. While combining lime (0.5 ml/kg) and lemon (0.5 and 1.0 ml/kg) juices with the drug did not have any synergistic effect.

RESUMEN

We measured the effect of varieties of Fig leaves, Ficus exasperata Vahl. (FE) and Ficus asperifolia Miq (FA), commonly found in Sub-sahara Africa for managing hypertension on sexual performance in hypertensive rats, which is unknown. Hypertensive rats experienced erectogenic damage after exposure to 40 mg kg-1  bw-1 , N(G)-nitro-l-arginine-methyl-ester (L-NAME). Experimental rats were grouped into eight groups (n = 6) namely: control rats, hypertensive rats, hypertensive treatment groups with atenolol (10 mg kg-1  day-1 ) and sildenafil (5.0 mg/kg), rats treated with FE- and FA-formulated biscuits at proportions of 2.5 g and 5.0 g respectively. Furthermore, we measured the level of sexual performance (Intromission number, latency, Mounting number, and latency), hormonal levels, phosphodiesterase-5 enzyme (PDE-5) activity and genes expressed using real-time quantitative polymerase chain reaction (RT-qPCR) in hypertensive rats. The result deduced revealed that treated hypertensive rats showed significantly reduced follicle-stimulating hormone, luteinising hormone levels, PDE-5 enzyme activity, tumour necrosis factor-alpha (TNF-α) expression while having a marked increase in testosterone level, sexual performance and endothelial nitric oxide synthase (eNOS) expression. Therefore, this study revealed the comparative dietary enhancing effect of FE- and FA-formulated biscuit on sexual behaviour activity, hormonal levels and the level of eNOS and TNF-α genes expressed in hypertensive rats.

RESUMEN

This study evaluated the effects of ice creams produced from blends of orange (Citrus sinensis) and shaddock (Citrus maxima) peels on the blood lipid profile, glycemic index, and antioxidant indices in the liver and heart of rats. Formulated ice cream was produced at a different proportion of citrus (orange and shaddock) blends and fed to rats for 28 days. The result showed that the formulated ice cream enriched with citrus peels blends caused a significant increase in high-density lipoprotein-cholesterol level in the plasma and antioxidant status in the liver and heart homogenates, decreased the glycemic index, concentration of total cholesterol, triglycerides, and low-density lipoprotein in the plasma as against rats fed on plain and commercial ice creams. To conclude, the use of ice creams from blends of orange and shaddock peels could serve as a functional food for weight reduction, glycemic index, management of lipid-related diseases, and prevention of oxidative stress-related complications in the liver and heart. PRACTICAL APPLICATIONS: The consumption of ice creams has increased in many parts of the world. However, there have been limited efforts aimed at improving the medicinal properties of frozen dairy products. Hence, these ice creams could be produced on a large scale under regulated condition since they have improved medicinal properties which would be a good option for preventing/combating degenerative conditions and their related complications.

RESUMEN

Hypertension is a global health problem. Statistics report from the World Health Organization reveals its prevalence in about a quarter of the world global population. Due to the complications associated with hypertension, it is required to be well managed or prevented pharmacologically or non-pharmacologically. Pharmacologically, the major antihypertensive drugs used are centrally acting sympatholytic drugs, diuretics, vasodilators, angiotensin converting enzyme inhibitors, and angiotensin II receptor blockers while non-pharmacological means of management include lifestyle changes, intake of diet or supplements with antihypertensive effects. Interestingly, the use of diet as a complement with drug intake has become very popular due to occurring side effects over time. Recent research efforts have revealed that foods such as fruits and vegetables contain bioactive substances that modulate the activities of macromolecules involved in the development, complications, and management of hypertension. PRACTICAL APPLICATIONS: Recent research efforts have suggested the efficacy of diets rich in fruits and vegetables in the management of hypertension. This review examines some of the mechanisms involved in the dietary management or prevention of hypertension by bioactive compounds found in foods. This review promotes the use of diet in the management of the condition and also suggests that precautions to be taken in the combined use of food and drugs.
