Abstract
Purpose This current research study was designed to investigate beneficial effects of R. humilis (Rivina humilis) against streptozotocin-induced diabetic rats. Methods The R. humilis ethanol extract was prepared using soxhlet and its phenol content was determined. The type-2 diabetes was induced in rats by giving fructose mixed drinking water and single dose of streptozotocin. Oral glucose tolerance test (OGTT) was performed after 72 h of streptozotocin to check ability of extract to utilize oral glucose load with 2 h. The extract was also tested for its potentials to reduce blood glucose (BGL) and diabetic complications by administering to diabetic rats for 21 days. Blood glucose was determined on day 1, 7, 14 and 21. At 21st day, blood samples were collected from experimental rats were euthanized to collect pancreas and liver. Liver and kidney function tests, HbAc1 and lipid profile was established from blood samples. Pancreas was subjected to histopathological examination and liver was used to determine antioxidant enzymes. In vitro study was done to investigate the effect of extract on glucose utilization by rat hemidiaphragm. Results In OGTT, administration of extract could stimulate glucose utilization which was witnessed by significant BGL reduction at 90 and 120 min in therapeutic groups compare to diabetics. In chronic study, we observed significant reduction in BGL on 21st day and all tests performed to determine liver and kidney function, HbAc1, vitamin E were normal in extract treated groups. There was significant increase in liver antioxidant enzymes in therapeutic groups which revealed regeneration of β-cells in therapeutic groups. Conclusion The results of research demonstrated significant antidiabetic potentials in R. humilis.

Abstract
Coalescence of traditional medicine Ayurveda and in silico technology is a rigor for supplementary development of future-ready effective traditional medicine. Ayurveda is a popular traditional medicine in South Asia, emanating worldwide for the treatment of metabolic disorders and chronic illness. Techniques of in silico biology are not much explored for the investigation of a variety of bioactive phytochemicals of Ayurvedic herbs. Drug repurposing, reverse pharmacology, and polypharmacology in Ayurveda are areas in silico explorations that are needed to understand the rich repertoire of herbs, minerals, herbo-minerals, and assorted Ayurvedic formulations. This review emphasizes exploring the concept of Ayurveda with in silico approaches and the need for Ayurinformatics studies. It also provides an overview of in silico studies done on phytoconstituents of some important Ayurvedic plants, the utility of in silico studies in Ayurvedic phytoconstituents/formulations, limitations/challenges, and prospects of in silico studies in Ayurveda. This article discusses the convergence of in silico work, especially in the least explored field of Ayurveda. The focused coalesce of these two domains could present a predictive combinatorial platform to enhance translational research magnitude. In nutshell, it could provide new insight into an Ayurvedic drug discovery involving an in silico approach that could not only alleviate the process of traditional medicine research but also enhance its effectiveness in addressing health care.

Abstract
IMPORTANCE One of the consequential and alarming complications of diabetes mellitus is diabetic neuropathy (DN). DN is assured to be caused chiefly by excess sorbitol levels in the body. The harmful consequences of DN alike peripheral nerve damage with extremity ulcers may be dodged with timely detection and treatment. The therapeutic methods for DN are scarce and expensive. Therefore economic and user friendly methodologies to prevent acquiring the disease need proper attention. OBJECTIVE The present research has been conducted (1) to analyse the levels of sorbitol in diabetic blood samples and compare them with non-diabetic ones and (2) to study the reduction in sorbitol levels upon addition of an important biochemical compounds caffeine in both sample groups. RESEARCH DESIGN, SETTING, PARTICIPANTS AND METHOD Sorbitol-caffeine interaction analysis of blood samples of 16 patients with type 2 diabetes from KPC Medical College, Kolkata, India was made. The spectroscopic analysis and their interpretations were compared with 16 healthy subjects. MAIN OUTCOMES AND MEASURES Present work describes that caffeine can be helpful in reducing the sorbitol level in diabetics, so the chances of development and progression of diabetic neuropathy can be controlled with the introduction of caffeine. RESULTS A total number of 32 blood samples of patients (aged 35-70 years); mean age ranges were 52.06 ± 2.68 and 53.50 ± 2.66 years for non-diabetic and diabetic ones respectively, glucose and sorbitol screening examination were done by enzymatic methodologies where concentrations were assessed by means of either absorption or fluorescence spectroscopy. The calibration range was 18.2-1119.3 mg/dL (Linear regression analysis r2 = 0.996). The sensitivity of this screening program in detecting DN with the healthy adults has been inquired and found efficient. Results of fasting insulin analyses have also been analysed for HOMA-IR (homeostasis model assessment - insulin resistance) and HOMA-B (homeostasis model assessment - pancreatic β cell function) values. Statistical significance of the results in non-diabetic and diabetic groups were performed and found to be statistically significant. CONCLUSIONS We have defined the relationship between blood glucose level, insulin level, sorbitol and caffeine in human body and utilized them in the plausible remediation of DN.

Abstract
Tropical and subtropical fruits are recognized as a source of a high content of bioactive compounds and health promoting properties due to their nutritional composition. These beneficial health effects are related to the content of several of these bioactive compounds, mainly flavonoids and non-flavonoid phenolics. Many of these compounds are common in different tropical fruits, such as epicatechin in mango, pineapple, and banana, or catechin in pineapple, cocoa or avocado. Many studies of tropical fruits had been carried out, but in this work an examination is made in the current literature of the flavonoids and non-flavonoid phenolics content of some tropical fruits and their coproducts, comparing the content in the same units, as well as examining the role that these compounds play in health benefits.

Abstract
Diabetic retinopathy (DR) is an important complication of diabetes, and is currently the main cause of blindness among young adults in the world. Previous studies have shown that Keluoxin (KLX) capsules have a significant effect on DR in C57BL/KsJ/db-/- mice (db/db mice), however the unclear mechanism limits its further clinical application and actual value. Further research is urgently needed for the treatment of DR disease. Discovery of key lipid biomarkers and metabolic pathways can reveal and explore the molecular mechanisms related to DR development and discover the effect of Keluoxin (KLX) capsule against DR in db/db mice. Lipidomics has been used for characterizing the pathological conditions via identification of key lipid metabolites and the metabolic pathway. In this study, the high-throughput lipidomics using UHPLC-Q-TOF/MS combined with multivariate statistical analysis, querying multiple network databases and employing ingenuity pathway analysis (IPA) method for molecular target prediction. A total of 30 lipid biomarkers were identified and 7 metabolic pathways including arachidonic acid metabolism and steroid hormone biosynthesis were found. The preventive effect of KLX intervention can regulate 22 biomarkers such as LysoPA(16:0/0:0), prostaglandin D2, cortisol and γ-linolenic acid, etc. IPA platform has predicted that PI3K/MAPK pathway are closely related to DR development. It also showed that high-throughput lipidomics combined with multivariate statistical analysis could deep excavate of the biological significance of the big data, and can provide molecular targets information about the disease treatment.

Abstract
A 40-year-old woman, known type 2 diabetes mellitus, obese (100 kg), on insulin (80 units), was under treatment for unstable proliferative diabetic retinopathy with extramacular tractional retinal detachment (TRD) in the left eye. At 1-year follow-up, she developed progression of TRD involving the macula in the left eye for which she was advised surgery. She did not follow-up for 6 months during which time she had adopted a coconut oil-rich ketogenic diet. She reported losing 25 kg body weight along with reversal of diabetes (Glycosylated Haemglobin (HbA1C) of 5.3% without insulin) in the interim. During this 2-year follow-up visit, it was found that there was complete resolution of macular detachment due to TRD in the left eye with stable vision. This was attributed to the impactful ketogenic diet.

Abstract
Virgin coconut oil (VCO) is a functional food oil prepared from fresh coconut kernel either by hot-processed (HPVCO) or fermentation-processed (FPVCO). The FPVCO has been widely explored for its pharmacological efficacy; while HPVCO, which has traditional uses, is less explored. The present study compared the phenolic content and nephroprotective effect of both these oils in male Wistar rats. In vitro antioxidant activity was estimated in terms of 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging, ferric reducing antioxidant power and ex vivo lipid peroxidation inhibition. In in vivo models, the rats were pretreated orally with of FPVCO or HPVCO (doses 2 and 4 mL/kg) for seven days and nephrotoxicity was induced by the single intraperitoneal injection of cisplatin (10 mg/kg). The results indicated significantly higher polyphenol content in HPVCO (400.3 ± 5.8 µg/mL) than that of FPVCO (255.5 ± 5.8 µg/mL). Corroborating with the increased levels of polyphenols, the in vitro antioxidant potential was significantly higher in the HPVCO. Further, pretreatment with these VCO preparations protected the rats against the cisplatin-induced nephrotoxicity, with higher extent by HPVCO. The renal function markers like urea, creatinine and total bilirubin were significantly reduced (p < 0.05) with HPVCO pretreatment. Apart from the nephroprotective effects, HPVCO also abrogated the cisplatin-induced myelosuppression and hepatotoxicity. The restoration of hepato-renal function by the pretreatment of HPVCO was well corroborated with the improvement in functional antioxidants and subsequent reduction in renal lipid peroxidation. Supporting these observations, renal histology revealed reduced glomerular/tubular congestion and necrosis. Thus, the study concludes that HPVCO may be better functional food than FPVCO.

Abstract
Diabetes mellitus is a metabolic disorder that majorly affects the endocrine gland, and it is symbolized by hyperglycemia and glucose intolerance owing to deficient insulin secretory responses and beta cell dysfunction. This ailment affects as many as 451 million people worldwide, and it is also one of the leading causes of death. In spite of the immense advances made in the development of orthodox antidiabetic drugs, these drugs are often considered not successful for the management and treatment of T2DM due to the myriad side effects associated with them. Thus, the exploration of medicinal herbs and natural products as therapeutic sources for the treatment of T2DM is promoted because they have little or no side effects. Bioactive molecules isolated from natural sources have been proven to lower blood glucose levels via regulating one or more of the following mechanisms: improvement of beta cell function, insulin resistance, glucose (re)absorption, and glucagon-like peptide-1 homeostasis. In recent times, the mechanisms of action of different bioactive molecules with antidiabetic properties and phytochemistry are gaining a lot of attention in the area of drug discovery. This review article presents an update of the findings from clinical research into medicinal plant therapy for T2DM.

Abstract
Coconut oil (CO) is enriched with medium chain saturated fatty acids like lauric acid (LA), capric acid and caprylic acid, which are known to have several health benefits. LA, the predominant fatty acid in CO, is reported to possess anticancer activity mediated through oxidative stress-induced apoptosis; however, there is no clear information on its cellular signalling mechanism. The present study screened the anticancer potential of various fatty acids present in CO (capric acid, caprylic acid and LA) using in silico tools such as CDOCKER in Accelrys Discovery Studio by targeting proteins like epidermal growth factor receptor (EGFR), cyclin-dependent kinase and thymidine synthase (TS). The results were further confirmed using cell culture-based studies and quantitative PCR. Among the tested compounds, LA was found to be the most active and showed a higher affinity towards EGFR and TS. Corroborating with these results, LA-induced dose-dependent cytotoxicity towards HCT-15 (human colon cancer), HepG2 (human hepatocellular carcinoma) and Raw 264.7 (murine macrophages) cells exhibiting morphological characteristics of apoptosis. Further, in HCT-15 cells exposed to LA (30 and 50 µg/mL), the expression of EGFR was found to be downregulated by 1.33- and 1.58-fold. The study thus concludes that the anticancer activity of LA may be partially mediated by the downregulation of EGFR signalling and consequent reduction in cell viability through apoptosis. Since EGFR signalling is crucial in cancer cell survival and is a prime target in drug development, the present study has pharmacological significance.
