Exploring AyuGenomics approach for understanding COVID-19 predisposition and progression.

Recent reports on COVID-19 suggest that, the susceptibility to COVID-19 infection and its progression have a genetic predisposition. Majorly associated genetic variants are found in human leukocyte antigen (HLA), angiotensin convertase enzyme (ACE; rs1799752: ACE2; rs73635825, and transmembrane protease serine 2 (; rs12329760 genes. Identifying highly prone population having these variants is imperative for determining COVID-19 therapeutic strategies.

Ayurveda botanicals in COVID-19 management: An in silico multi-target approach.

The Coronavirus disease (COVID-19) caused by the virus SARS-CoV-2 has become a global pandemic in a very short time span. Currently, there is no specific treatment or vaccine to counter this highly contagious disease. There is an urgent need to find a specific cure for the disease and global efforts are directed at developing SARS-CoV-2 specific antivirals and immunomodulators.

(L.) Dunal: Opportunity for Clinical Repurposing in COVID-19 Management.

As the COVID-19 pandemic is progressing, the therapeutic gaps in conventional management have highlighted the need for the integration of traditional knowledge systems with modern medicine. Ayurvedic medicines, especially Ashwagandha ( (L.) Dunal, WS), may be beneficial in the management of COVID-19.

Management of Type 2 Diabetes: Current Strategies, Unfocussed Aspects, Challenges, and Alternatives.

Type 2 diabetes mellitus (T2DM) accounts for >90% of the cases of diabetes in adults. Resistance to insulin action is the major cause that leads to chronic hyperglycemia in diabetic patients. T2DM is the consequence of activation of multiple pathways and factors involved in insulin resistance and β-cell dysfunction.

Withania somnifera (L.) Dunal: A potential therapeutic adjuvant in cancer.

Ethnopharmacological Relevance: Withania somnifera (L.) Dunal (WS) is one of the moststudied Rasayana botanicals used in Ayurveda practice for its immunomodulatory, anti-aging, adaptogenic, and rejuvenating effects. The botanical is being used for various clinical indications, including cancer.

Understanding the relevance of herb-drug interaction studies with special focus on interplays: a prerequisite for integrative medicine.

Integrative medicine refers to the blending of conventional and evidence-based complementary medicines and therapies with the aim of using the most appropriate of either or both modalities for ultimate patient benefits. One of the major hurdles for the same is the chances of potential herb-drug interactions (HDIs). These HDIs could be beneficial or harmful, or even fatal; therefore, a thorough understanding of the eventualities of HDIs is essential so that a successful integration of the modern and complementary alternative systems of medicine could be achieved.

Targeting receptors of advanced glycation end products (RAGE): Preventing diabetes induced cancer and diabetic complications.

Cancer and diabetes are the two major disorders that affect a large proportion of the world's population. Results from multiple epidemiological studies have concluded that diabetes and cancer are linked, and diabetic patients live at much higher risks of developing cancer and diabetic complications at the later phase of disease. Inflammation is the central pathway that mediates both diabetic complications as well as cancer.

Antidiabetic properties of aqueous and methanol extracts from the trunk bark of Ceiba pentandra in type 2 diabetic rat.

The type 2 diabetes is one of the major global health issues that affects millions of people. This study evaluated the antidiabetic activity of aqueous extracts (AECP) and methanol extracts (MECP) from Ceiba pentandra trunk bark on an experimental model of type 2 diabetes (T2D). This model was induced in rats by the combination of a high-fat diet (HFD) and a single dose of streptozotocin (40 mg/kg, intraperitoneal) at the seventh day of experimentation.

In vitro and in vivo anticancer efficacy potential of Quercetin loaded polymeric nanoparticles.

Quercetin (QCT) is a flavonoid, abundantly present in plants and has gained considerable interest for its antioxidant property and chemo preventive activity. Bioavailability of QCT is very low due to its poor aqueous solubility and instability. Researchers are working on the application of nanotechnology to target chemotherapeutic drugs to the tumour site.

Potential synergistic effects of quercetin with other phytoconstituents of Costus pictus (insulin plant) extract in the control of hyperglycemia and prevention of NSAID-induced gastroenteropathy in diabetic rats.

There is a need of multifactorial management to treat T2DM. Till date, no clinically simulated animal model and therapy for NSAID-induced gastroenteropathic damage (NSAID-iGD) in T2DM patients. T2DM was developed using high-fat diet plus multiple low doses of streptozotocin (30 mg/kg, IP).

Curcumin, a component of turmeric, efficiently prevents diclofenac sodium-induced gastroenteropathic damage in rats: A step towards translational medicine.

There is a need to find/discover novel leads to treat complex and/or multi-factorial disease(s). Curcumin (CUR) is one of the promising lead molecules which need its further evaluation against NSAID-induced gastroenteropathy. Hence, the aim of the present study was to explore the pharmaco-mechanistic efficacy of CUR against NSAID-induced gastroenteropathy.

Overcoming the exacerbating effects of ranitidine on NSAID-induced small intestinal toxicity with quercetin: Providing a complete GI solution.

There is a need to find/discover novel leads to treat complex and/or multi-factorial-pathogenic disease(s) like Nonsteroidal anti-inflammatory drugs (NSAID)-induced gastroenteropathy or gastrointestinal (GI) toxicity as it has emerged as an important medical and socioeconomic problem. There is no approved therapeutic strategy to prevent NSAID-induced enteropathic damage and highly effective gastro-protective drugs such as ranitidine hydrochloride (RAN) exacerbate it. In this purview, the multi target drug discovery approach (MTDD), combination approach and hit to lead strategies based on the foundation of ethnopharmacology and/or reverse pharmacology holds strong potential.

Co-administration of quercetin with pantoprazole sodium prevents NSAID-induced severe gastroenteropathic damage efficiently: Evidence from a preclinical study in rats.

Management of Nonsteroidal anti-inflammatory drug (NSAID)-induced gastroenteropathy has emerged as a major medical and socioeconomic problem mainly because the highly efficacious gastroprotective drugs i.e. proton pump inhibitors (PPIs) like pantoprazole sodium (PTZ), worsen the NSAID-induced enteropathic damage and lack of approved therapeutic strategies/interventions to prevent this damage.

Clinical importance of nonsteroidal anti-inflammatory drug enteropathy: the relevance of tumor necrosis factor as a promising target.

The pathogenesis of nonsteroidal anti-inflammatory drug (NSAID) enteropathy is still unclear, and consequently, there is no approved therapeutic strategy for ameliorating such damage. On the other hand, molecular treatment strategies targeting tumor necrosis factor (TNF) exerts beneficial effects on NSAID-induced intestinal lesions in rodents and rheumatoid arthritis patients. Thus, TNF appears to be a potential therapeutic target for both the prevention and treatment of NSAID enteropathy.

A novel model for NSAID induced gastroenteropathy in rats.

Introduction: Progress in management of Nonsteroidal anti-inflammatory drug (NSAID) induced gastrointestinal toxicity requires the availability of appropriate experimental animal models that are as close to humans as feasible. Our objective was to develop a rat model for NSAID-induced gastroenteropathy and also to simulate the common clinical scenario of co-administration of NSAID and proton pump inhibitor (PPI) to explore if PPI contribute to exacerbation of NSAID-enteropathy.

Methods: Rats were treated twice daily with pantoprazole sodium (PTZ; 10mg/kg peroral) or vehicle for a total of 10days.
