1. Diabetic chronic wounds, mainly foot ulcers, constitute one of the most common complications of poorly managed diabetes mellitus. The most typical reasons are insufficient glycemic management, latent neuropathy, peripheral vascular disease, and neglected foot care. In addition, it is a common cause of foot osteomyelitis and amputation of the lower extremities. Patients are admitted in larger numbers attributable to chronic wounds compared to any other diabetic disease. In the United States, diabetes is currently the most common cause of non-traumatic amputations. Approximately five percent of diabetics develop foot ulcers, and one percent require amputation. Therefore, it is necessary to identify sources of lead with wound-healing properties. Redox imbalance due to excessive oxidative stress is one of the causes for the development of diabetic wounds. Antioxidants have been shown to decrease the progression of diabetic neuropathy by scavenging ROS, regenerating endogenous and exogenous antioxidants, and reversing redox imbalance. Matrix metalloproteinases (MMPs) play vital roles in numerous phases of the wound healing process. Antioxidant and fibroblast cell migration activity of Marantodes pumilum (MP) crude extract has previously been reported. Through their antioxidant, epithelialization, collagen synthesis, and fibroblast migration activities, the authors hypothesise that naringin, eicosane and octacosane identified in the MP extract may have wound-healing properties. 2. The present study aims to identify the bioactive components present in the dichloromethane (DCM) extract of M. pumilum and evaluate their antioxidant and wound healing activity. Bioactive components were identified using LCMS, HPTLC and GCMS. Excision wound on STZ-induced diabetic rat model, human dermal fibroblast (HDF) cell line and colorimetric antioxidant assays were used to evaluate wound healing and antioxidant activities, respectively. Molecular docking and pkCMS software would be utilised to predict binding energy and affinity, as well as ADME parameters. 3. Naringin (NAR), eicosane (EIC), and octacosane (OCT) present in MP displayed antioxidant action and wound excision closure. Histological examination HDF cell line demonstrates epithelialization, collagen production, fibroblast migration, polymorphonuclear leukocyte migration (PNML), and fibroblast movement. The results of molecular docking indicate a substantial attraction and contact between MMPs. pkCMS prediction indicates inadequate blood-brain barrier permeability, low toxicity, and absence of hepatotoxicity. 4. Wound healing properties of (NEO) naringin, eicosane and octacosane may be the result of their antioxidant properties and possible interactions with MMP.

Objective: Marantodes pumilum (MP) is a plant widely used in traditional medicine in the Southeast Asian region and been reported to possess anti-inflammatory, analgesic, antipyretic, and antiulcer properties. The aim of the study is to identify the bioactive phytochemicals present in the purified leaf extract of MP using gas chromatography mass spectrometry (GC-MS), and to determine their anti-inflammatory, analgesic, and antipyretic effect in a rat model. Methods: A dichloromethane crude extract of MP was partially purified using column chromatography, and the bioactive compounds were identified using GC-MS. The anti-inflammatory, analgesic, and antipyretic activities of the identified bioactive compounds were evaluated using formalin, carrageenan, acetic acid, and brewer’s yeast to induce the rats. Results: Eicosane, pentadecane, octacosane, and heneicosane were identified as bioactive compounds in purified leaf extract of MP. These bioactive compounds did not show any toxicity on the rats at 1000 mg/kg. There was no mortality, and no apparent behavioral, physiological, and morphological changes of the internal organs occurred. They exhibited a very significant (p<0.05) dose-dependent inhibition of acetic acid-induced writhing, formalin-induced paw licking, carrageenan-induced paw edema, and brewer’s yeast-induced pyrexia. Conclusions: Eicosane and pentadecane were able to show very strong anti-inflammatory, analgesic, and antipyretic effects. The observed effects of the bioactive compounds are similar to previous reports on crude and partially purified leaf extract of MP. The finding suggests that eicosane and pentadecane maybe the major bioactive compounds present in the purified leaf extract of MP.

Background: Energy drinks (EDs) are a type of beverage that mostly contains caffeine and other dietary supplements (if present) and does not contain any alcohol in the ingredients. The products in this category include Red Bull, Redline, Monster, Full Throttle, and others. They are claimed to help in boosting energy, stamina, sports performance, and concentration among individuals. This article focused on the review of the benefits and disadvantages of consumption of energy drinks to health and well-being. ED provides health benefits effects such as improved physical performance, mood and attitude, cognition, and weight loss. Some adverse negative health challenges have been linked to consumption of ED. Therefore, this review is a wholistic appraisal of benefits or detriments of consumption of energy drink to our health and suggestions to curtail the excesses of ED consumption.Main body: Energy drink has been around since 1950, and it is marketed as energy booster and comes in different types, energy shots, fruit-based, non-fruit-based (regular), sugar-free, and plant-based. These products are marketed as a low-calorie “instant” energy drink that can be consumed in a single sip, or bottle to boost energy or to boost the nutritional value of conventional products. Many of them contain different ingredients such as caffeine, guarana, ginseng, yerba mate, acai berry, ginkgo biloba, methylxanthines, sugar, glucuronolactone, taurine, maltodextrin, B vitamins. Vitamin B2 (riboflavin), B3 (niacin), B6 (pyridoxine, pyridoxal, and pyridoxamine), Inositol B8 and B12, vitamin C and vitamin D; calcium, Iron, chromium, zinc, manganese, molybdenum; artificial sweeteners, aspartame, and sucralose. Health benefits such as improved physical performance, improved mood and attitude, improved concentration, and memory, good source of vitamin B and weight loss have been reported. Negative impact on health such as adverse cardiovascular effect, headaches, epileptic seizures, ischemic stroke, hallucinations, muscular twitching, restlessness, sleeplessness, anxiety, depression, gastrointestinal effect, renal effects, dental effects, obesity and type II diabetes, cancer, and caffeine toxicity has been reported.Conclusions: Most of the health detriments caused because of consumption of energy drink is mostly due to the presence of excess quantity of caffeine and sugar. If the quantities of caffeine and sugar content in energy drink are kept at FDA- and WHO-recommended daily consumption amount, then it will not be present any problem to health. Consumption of energy drink that contains natural ingredients such as yerba mate, acai berry, ginkgo biloba, methylxanthines, amino acid, guarana, and ginseng with moderate FDA- and WHO-approved daily consumption of caffeine and sugar is not detrimental to health.

Spirulina (blue-green algae) contains a wide range of nutrients with medicinal properties which include β-carotene, chromium, and moderate amounts of vitamins B₁₂. This study aims to determine the preventive effect of spirulina against bone fragility linked to type 2 diabetes mellitus. Thirty Sprague-Dawley rats were divided into five groups (n = 6) and diabetes was induced using streptozocin. Rats with a plasma glucose level of 10 mmol/L and above were orally treated for twelve weeks with either a single dose of spirulina, metformin, or a combined dose of spirulina + metformin per day. After the treatment, blood and bones were taken for biochemical analysis, three-dimensional imaging, 3-point biomechanical analysis, histology imaging and gene expression using qPCR. Results showed that diabetes induction and treatment with metformin caused destruction in the trabecular microarchitecture of the femur bone, reduction in serum bone marker and expression of bone formation marker genes in the experimental rats. Spirulina supplementation showed improved trabecular microarchitecture with a denser trabecular network, increased 25-OH vitamin D levels, and lowered the level of phosphate and calcium in the serum. Biomechanical tests revealed increased maximum force, stress strain, young modulus and histology images showed improvement in regular mesh and an increase in osteoblasts and osteocytes. There was an increase in the expression of bone formation marker osteocalcin. The results suggest that spirulina supplementation was more effective at improving bone structural strength and stiffness in diabetic rats compared to metformin. Spirulina may be able to prevent T2DM-related brittle bone, lowering the risk of fracture.

Context: Oxidative stress and formation of advanced glycation end products (AGEs), due to glycation of proteins, lipids and nucleic acids are characteristic in diabetic patients. Palmatine, a protoberberine alkaloid bioactive isolated from Coscinium fenestratum (CF) stem extract, which previously has shown to possess antidiabetic and antioxidant properties and to be able to protect the kidney and liver in a STZ-diabetic induced rat model. Aims: To evaluate the in vitro and in vivo antioxidant and anti-AGE activity of palmatine. Methods: In vitro and in vivo studies were conducted to measure radical scavenging, reducing power, inhibition of lipid peroxidation, carbonyl trapping and metal ion chelation. In vitro antiglycation activity was done using bovine serum albumin-methylglyoxal (BSA-MGO), bovine serum albumin – glucose (BSA-GLU) and glycated hemoglobin. In vivo antioxidant and antiglycation activity were used to evaluate liver and kidney extracted from STZ-induced diabetic rat after treatment with palmatine. Results: The results showed palmatine blocked the formation of AGE as shown by the results of BSA-GLU, BSA-MGO, glycated hemoglobin and inhibited the free radicals generated by DPPH, nitric oxide, hydrogen peroxide, lipid peroxidation, FRAP and metal ion chelating. It was able to stimulate in vivo the activity of catalase, super oxide dismutase and glutathione peroxidase. Conclusions: Palmatine possess antioxidant and antiglycation properties, the mechanism of action seems to be via the blockage of free radical formation, decreasing of reactive carbonyl. Further research is ongoing to determine the effect of palmatine on glyoxalase 1 and aldose reductase pathway and interaction with receptor for AGE.
