COVID-19 pandemic: A pragmatic plan for ayurveda intervention.

World community is facing an unprecedented pandemic of novel corona virus disease (COVID-19) caused by Severe Acute Respiratory Syndrome Corona virus 2 (SARS-CoV- 2). The disease has spread globally with more than 1.43 million confirmed cases and 82,100 deaths as of April 8, 2020. Despite worldwide efforts to contain it, the pandemic is continuing to spread for want of a clinically-proven prophylaxis and therapeutic strategy. The dimensions of pandemic require an urgent harnessing of all knowledge systems available globally. Utilization of Traditional Chinese Medicine in Wuhan to treat COVID-19 cases sets the example demonstrating that traditional health care can contribute to treatment of these patients successfully. Drawing on the Ayurveda classics, contemporary scientific studies, and experiential knowledge on similar clinical settings, here we propose a pragmatic plan for intervention in India. We provide a plan for graded response, depending on the stage of infection among individuals, in a population. Notwithstanding the fact that no system of medicine has any evidence-based treatment for COVID-19 as yet, clinical interventions are required to be put in place. Therefore, pragmatic strategy proposed here for Ayurveda system of medicine requires immediate implementation. It will facilitate learning, generate evidence and shall be a way forward.

Dietary Approaches to Stop Hypertension via Indo-Mediterranean Foods, May Be Superior to DASH Diet Intervention.

Western-type diet with high salt and sugar, sedentary behavior, obesity, tobacco and alcoholism are important risk factors for hypertension. This review aims to highlight the role of western diet-induced oxidative stress and inflammation in the pathogenesis of hypertension and the role of various types of diets in its prevention with reference to dietary approaches to stop hypertension (DASH) diet. It seems that it is crucial to alter the western type of diet because such diets can also predispose all CVDs. Western diet-induced oxidative stress is characterized by excessive production of reactive oxygen species (ROS) with an altered oxidation-reduction (redox) state, leading to a marked increase in inflammation and vascular dysfunction. Apart from genetic and environmental factors, one important cause for differences in the prevalence of hypertension in various countries may be diet quality, deficiency in functional foods, and salt consumption. The role of the DASH diet has been established. However, there are gaps in knowledge about the role of some Indo-Mediterranean foods and Japanese foods, which have been found to decrease blood pressure (BP) by improving vascular function. The notable Indo-Mediterranean foods are pulses, porridge, spices, and millets; fruits such as guava and blackberry and vegetables, which may also decrease BPs. The Japanese diet consists of soya tofu, whole rice, in particular medical rice, vegetables and plenty of fish rich in fish oil, fish peptides and taurine that are known to decrease BPs. Epidemiological studies and randomized, controlled trials have demonstrated the role of these diets in the prevention of hypertension and metabolic diseases. Such evidence is still meager from Japan, although the prevalence of hypertension is lower (15-21%) compared to other developed countries, which may be due to the high quality of the Japanese diet. Interestingly, some foods, such as berries, guava, pumpkin seeds, carrots, soya beans, and spices, have been found to cause a decrease in BPs. Omega-3 fatty acids, fish peptide, taurine, dietary vitamin D, vitamin C, potassium, magnesium, flavonoids, nitrate and l-arginine are potential nutrients that can also decrease BPs. Larger cohort studies and controlled trials are necessary to confirm our views.

Chicken Feather Waste Hydrolysate as a Superior Biofertilizer in Agroindustry.

Billions of tons of keratinous waste in the form of feathers, antlers, bristles, claws, hair, hoofs, horns, and wool are generated by different industries and their demolition causes environmental deterioration. Chicken feathers have 92% keratin that can be a good source of peptides, amino acids, and minerals. Traditional methods of feather hydrolysis require large energy inputs, and also reduce the content of amino acids and net protein utilization values. Biological treatment of feathers with keratinolytic microbes is a feasible and environmental favorable preference for the formulation of hydrolysate that can be used as bioactive peptides, protein supplement, livestock feed, biofertilizer, etc. The presence of amino acids, soluble proteins, and peptides in hydrolysate facilitates the growth of microbes in rhizosphere that promotes the uptake and utilization of nutrients from soil. Application of hydrolysate enhances water holding capacity, C/N ratio, and mineral content of soil. The plant growth promoting activities of hydrolysate potentiates its possible use in organic farming, and improves soil ecosystem and microbiota. This paper reviews the current scenario on the methods available for management of keratinous waste, nutritional quality of hydrolysate generated using keratinolytic microbes, and its possible application as plant growth promoter in agroindustry.

Principle of Hot (Ushna) and Cold (Sheeta) and Its Clinical Application in Ayurvedic Medicine.

Hot (Ushna) and cold (sheet) are two fundamental precepts of Ayurvedic medicine reflected variously within the context of health and disease. These are fundamental for being essential attributes of three doshas, namely, Vata, Pitta, and Kapha, forming the very basis of Ayurvedic constructs of health and disease. Ushna is the inherent property of Pitta, symbolizing fire both inside and outside the body. There are pathologies of Pitta where this Ushna property participates in pathogenesis to present the features like burning, sour eructation, and fever. In such cases, the course of treatment eventually focuses on reducing Pitta or reducing the Ushna property of Pitta, in particular. A similar cold association is found with Vata and Kapha, where the pathogenesis is reflected as heaviness, cold and cough, and edema. The treatment of Vata and Kapha diseases eventually focuses upon their reduction or reducing cold-related pathogenesis, in particular. This is evident that these two form an essential and integral component of Ayurvedic understanding of health and disease and are practically applied to make a diagnosis and define the treatment. In this chapter, we are expanding the details of Ushna and Sheeta constructs of Ayurvedic medicine and elaborating on their health and disease application.

Influence of Metabolic Status and Diet on Early Pregnant Equine Histotroph Proteome: Preliminary Findings.

Insulin resistance (IR) is characterized by an increase in biomarkers of systemic inflammation and susceptibility to laminitis in horses. Impacts on reproduction include a lengthened interovulatory period in horses. Dietary omega-3 (docosahexaenoic acid [DHA]) promotes anti-inflammatory processes, has been implicated in health benefits, and can reduce cytokine secretion. This preliminary study investigated the impact of IR as well as the influence of dietary supplementation (DHA) on the uterine fluid proteome in early pregnant horses. Mares were artificially inseminated; uterine fluid and embryos were collected on d 12.5 after ovulation. Uterine fluid was pooled for metabolic and diet categories (n = 8; n = 2 per metabolic and dietary status) and concentrated, and the proteome was analyzed using tandem mass spectrometry (iTRAQ). Five proteins met differential abundance criteria (±1.5-fold change, P < .05) in all comparisons (Control C, IS vs. C, IR; C, IS vs. DHA, IS; C, IR vs. DHA, IR). Serum amyloid A, afamin, and serotransferrin were upregulated in C, IR mares but downregulated in DHA, IR mares when compared to C, IS and C, IR, respectively. Quantitative PCR supported mass spectrometry results. The presence of serum amyloid A and serotransferrin in histotroph of IR mares potentially indicates an inflammatory response not seen in IS counterparts. These preliminary findings provide novel evidence on the potential impact of insulin resistance and DHA supplementation on the secreted equine uterine proteome during early pregnancy.

Telomerase Responsive Delivery of Doxorubicin from Mesoporous Silica Nanoparticles in Multiple Malignancies: Therapeutic Efficacies against Experimental Aggressive Murine Lymphoma.

Mammalian telomerase maintains the length and integrity of telomeres by adding the telomeric repeats to the chromosome end. This work describes the telomerase responsive delivery of doxorubicin against telomerase positive human and murine cancer cells. Wrapping of doxorubicin loaded mesoporous silica nanoparticles with specific oligonucleotide sequence, containing telomeric repeat complementary sequence and a telomerase substrate primer sequence, resulted in slow and sustained release of doxorubicin, contiguous to the tumor cells. The DNA wrapped nanoprobe significantly inhibits the proliferation and enhanced the cytotoxicity in telomerase positive human and mouse tumor cells, and its function is impeded following exposure to specific telomerase inhibitor, AZT. Entrapping of doxorubicin by telomerase specific oligo manifests enhanced apoptosis and significantly higher uptake of the drug in the tumor cells. Treatment of telomerase positive Dalton's lymphoma bearing mice with a novel and newly designed oligo wrapped nanoprobe, specific for mouse telomerase, significantly enhanced the survival and improved the histopathological parameters. In addition, the treatment also induced significant reduction in the number of tumor foci and restored the normal architecture of the vascularized organs, besides preventing metastasis.

Cryopreservation effects on sperm function and fertility in two threatened crane species.

The capacity to cryopreserve semen from captive cranes facilitates production of offspring from behaviorally incompatible or geographically separated pairs, and allows for long-term preservation of valuable genetic materials. The present study sought to develop effective cryopreservation protocols for whooping (Grus americana) and white-naped (Grus vipio) cranes, through examining the influences of two permeating (DMA and Me2SO) and one non-permeating (sucrose) cryoprotectants, as well as vitamin E on post-thaw sperm survival. In Study 1, ejaculates (whooping: n = 10, white-naped: n = 8) were collected and cryopreserved in one of six cryo-diluents (crane extender with: DMA; DMA+0.1M sucrose; Me2SO; Me2SO+0.1M sucrose; 0.1M sucrose; 0.2M sucrose) using a two-step cooling method. Frozen samples were thawed and assessed for overall motility, motion characteristics, membrane integrity, morphology, and ability to bind to the inner perivitelline membrane (IPVM). In Study 2, whooping crane ejaculates (n = 17) were frozen in crane extender containing Me2SO alone or with vitamin E (5 µg/mL or 10 µg/mL). Frozen samples were thawed and assessed as in Study 1, except the binding assay. White-naped crane sperm were more tolerant to cryopreservation than whooping crane (15% vs 6% post-thawed motility). In both species, sperm cryopreserved in medium containing Me2SO alone displayed higher post thaw survival and ability to bind to IPVM than the other cryodiluent treatments. Vitamin E supplementation exerted no benefits to post thaw motility or membrane integrity. The findings demonstrated that there was species specificity in the susceptibility to cryopreservation. Nevertheless, Me2SO was a preferred cryoprotectant for sperm from both whooping and white-naped cranes.

Hyperthermia effect and antibacterial efficacy of Fe3+ /Co2+ co-substitutions in ß-Ca3 (PO4 )2 for bone cancer and defect therapy.

The combined effect of cobalt and iron substitutions in ß-Ca3 (PO4 )2 as a potent material for application in hyperthermia and as a bone substitute is presented. Structural analysis reveals the preferential accommodation of Co2+ and Fe3+ at the Ca2+ (5) sites of ß-Ca3 (PO4 )2 until the limit of ∼10 mol % and, thereafter, prefer Ca2+ (4) lattice sites. Occupancy of both the Co2+ and Fe3+ ions induces a significant contraction of the ß-Ca3 (PO4 )2 unit cell. The Co2+ /Fe3+ co-substitutions in ß-Ca3 (PO4 )2 display magnetic characteristics that enhances hyperthermia effect. In addition, the presence of Co2+ in ß-Ca3 (PO4 )2 enunciates pronounced antibacterial efficacy against tested microorganisms. Nevertheless, the enhanced level of Co2+ in ß-Ca3 (PO4 )2 results to induce significant toxicity. The biocompatibility of the synthesized thermoseeds is verified from the hemolytic tests and cytotoxicity test performed on human sarcoma cell line MG-63. © 2017 Wiley Periodicals, Inc.

Aloe vera (Aloe barbadensis Miller) supplemented probiotic lassi prevents Shigella infiltration from epithelial barrier into systemic blood flow in mice model.

The aim of present work was to investigate preventive role of orally administered Aloe vera supplemented probiotic lassi (APL) on Shigella dysenteriae infection in mice. At the end of experimental period (2, 5 and 7 days of challenging), different organs such as spleen, liver, small intestine, large intestine, and peritoneal fluid were collected and assessed for Shigella colonization. Secretary IgA was estimated in intestinal fluid. Blood was collected in heparinized tubes for various haematological studies. Oral administration of APL showed a significant (p < 0.05) reduction in the Shigella counts (log cfu/mL) in all organs as compared to other treatment groups at different intervals after post feeding. Similarly, secretary IgA antibody levels (µg/mL) in intestinal fluid were significantly (p < 0.05) increased in case of APL fed mice. Further, feeding of APL also demonstrated a positive effect on different haematological parameters viz. Hb (gm %), RBC and WBC count. The results indicated the immunoprotective effects of APL against Shigella dysenteriae induced infection in mice.

Endoinulinase production by a new endoinulinase producer Aspergillus tritici BGPUP6 using a low cost substrate.

Endoinulinase is an inulolytic enzyme which is used for the production of fructooligosaccharides from inulin. A new endoinulinase producing fungal strain BGPUP6 was identified as Aspergillus tritici on the basis of its molecular characterization. Response surface methodology was used to optimize the endoinulinase production at shake-flask level from Aspergillus tritici BGPUP6 using raw Asparagus inulin as carbon source. Four independent variables (raw inulin, 2-4%; peptone, 0.3-0.7%; (NH4)H2PO4, 0.3-0.7% and pH, 4.5-6.5) were selected for the study based on the CCRD model of RSM. The other media supplements (FeSO4·7H2O, 0.001%; MgSO4·7H2O, 0.05% and KCl, 0.02%) were kept constant in the production medium, throughout the study. Endoinulinase production and biomass yield were selected as dependent responses. The optimal combination of media ingredients obtained from the study was 3% raw inulin, 0.5% peptone, 0.5% (NH4)H2PO4 and pH 5.5. Using the optimized media constituents, maximum endoinulinase production (25.01 IU/mL) and biomass yield (0.514g dry weight/50 mL) obtained were in good agreement with the predicted values. Crude enzyme produced was also used for the hydrolysis of inulin. The hydrolysate showed the presence of a mixture of fructooligosaccharides with varied degree of polymerization. This is the first report on the production of an endoinulinase from Aspergillus tritici.

Deposition, structure, physical and invitro characteristics of Ag-doped ß-Ca3(PO4)2/chitosan hybrid composite coatings on Titanium metal.

Pure and five silver-doped (0-5Ag) ß-tricalcium phosphate [ß-TCP, ß-Ca3(PO4)2]/chitosan composite coatings were deposited on Titanium (Ti) substrates and their properties that are relevant for applications in hard tissue replacements were assessed. Silver, ß-TCP and chitosan were combined to profit from their salient and complementary antibacterial and biocompatible features.The ß-Ca3(PO4)2 powders were synthesized by co-precipitation. The characterization results confirmed the Ag(+) occupancy at the crystal lattice of ß-Ca3(PO4)2. The Ag-dopedß-Ca3(PO4)2/chitosan composite coatings deposited by electrophoresis showed good antibacterial activity and exhibited negative cytotoxic effects towards the human osteosarcoma cell line MG-63. The morphology of the coatings was observed by SEM and their efficiency against corrosion of metallic substrates was determined through potentiodynamic polarization tests.

This review aims to give a comprehensive overview of traditional applications, current knowledge on the phytochemistry, pharmacology and overuse of A. racemosus.

Coenzyme Q10, α-tocopherol, and oxidative stress could be important metabolic biomarkers of male infertility.

Oxidative stress, decreased antioxidant capacity, and impaired sperm mitochondrial function are the main factors contributing to male infertility. The goal of the present study was to assess the effect of the per os treatment with Carni-Q-Nol (440 mg L-carnitine fumarate + 30 mg ubiquinol + 75 IU vitamin E + 12 mg vitamin C in each softsule) in infertile men on sperm parameters, concentration of antioxidants (coenzyme Q10, CoQ(10-TOTAL), γ, and α-tocopherols), and oxidative stress in blood plasma and seminal fluid. Forty infertile men were supplemented daily with two or three Carni-Q-Nol softsules. After 3 and 6 months of treatment, improved sperm density was observed (by 48.9% and 80.9%, resp.) and after 3-month treatment the sperm pathology decreased by 25.8%. Concentrations of CoQ(10-TOTAL) (ubiquinone + ubiquinol) and α-tocopherol were significantly increased and the oxidative stress was decreased. In conclusion, the effect of supplementary therapy with Carni-Q-Nol showed benefits on sperm function in men, resulting in 45% pregnancies of their women. We assume that assessment of oxidative stress, CoQ(10-TOTAL), and α-tocopherol in blood plasma and seminal fluid could be important metabolic biomarkers in both diagnosis and treatment of male infertility.

Hypoglycaemic effect of galactooligosaccharides in alloxan-induced diabetic rats.

This study was conducted to assess the effect of prebiotic galactooligosaccharides (GOS) on alloxan-induced diabetes in male Sprague-Dawley (SD) rats. Diabetes was induced by administration of alloxan (100 mg/kg) and rats were divided in 4 groups: normal control group (NCG), prebiotic control group (PCG), diabetic control group (DCG) and diabetic prebiotic group (DPG). While PCG and DPG were fed with GOS supplemented (10% w/w) diet, NCG and DCG were administered with basal diet. Rats were sacrificed after 42 d for collection of blood and liver. Faecal samples were collected at the interval of 7 d throughout the study for measurement of lactobacilli and coliform count. Feeding of GOS decreased or delayed the severity of diabetes by amelioration of diabetes associated markers including fasting blood glucose, haemoglobin, glycosylated haemoglobin triglycerides, total cholesterol, low density lipoproteins, creatinine and urea. GOS was also found to improve the levels of antioxidative enzymes (superoxide dismutase, catalase and glutathione peroxidase) in liver and blood. Improvement in lactobacilli count along with a concomitant decrease in coliform count was observed in GOS fed groups.

Effects of dietary supplementation of organic chromium (picolinate) on physical and biochemical characteristics of semen and carcass traits of male turkeys.

This experiment investigated the effect of dietary chromium (Cr as picolinate) on physical and biochemical characteristics of semen and carcass traits of adult male turkey. Seventy-two (72) male turkeys (16 weeks old) were randomly distributed into four dietary treatment groups (4×3×6) for a period of 24 weeks. Three experimental diets were supplemented with 250, 500 and 750µg Cr/kg (T2, T3 and T4 respectively) in basal diet (T1 considered as control). Semen physical characteristics viz. sperm concentration, progressive motility, live and dead count of spermatozoa and fertility differed significantly (P<0.05). Sperm concentration, progressive motility and fertility were higher and dead count was lower in T4 (750µg) group than control (T1) or other dietary treatments (T2 or T3) group. Semen biochemical parameters like creatinine, acid phosphatase (ACP) and alkaline phosphatase (ALP) concentration did not differ significantly among the dietary treatment groups, whereas, total protein, glucose, malondialdehyde (MAD) and cholesterol concentration differed significantly (P<0.05) amongst the treatment groups. Protein and MAD were higher while glucose and cholesterol concentrations were lower in T3 and T4 group than control or T1 group. The shrinkage loss, eviscerated yield, relative weight (as percent of body weight) of breast, thigh and liver improved on supplementation of Cr leading to significantly higher in T4 group in comparison to control. From this study, it could be concluded that supplementation of chromium as chromium picolinate, at 750µg/kg level in diet was beneficial for improving physical characteristics of semen, carcass yield and breast yield of adult male turkeys. However, Cr levels of 500 or 750µg/kg in diet were beneficial for semen biochemical parameters of adult male turkeys.

Comparison of saponin composition and content in wild soybean (Glycine soja Sieb. and Zucc.) before and after germination.

Eight wild soybean accessions with different saponin phenotypes were used to examine saponin composition and relative saponin quantity in various tissues of mature seeds and two-week-old seedlings by LC-PDA/MS/MS. Saponin composition and content were varied according to tissues and accessions. The average total saponin concentration in 1 g mature dry seeds of wild soybean was 16.08 ± 3.13 µmol. In two-week-old seedlings, produced from 1 g mature seeds, it was 27.94 ± 6.52 µmol. Group A saponins were highly concentrated in seed hypocotyl (4.04 ± 0.71 µmol). High concentration of DDMP saponins (7.37 ± 5.22 µmol) and Sg-6 saponins (2.19 ± 0.59 µmol) was found in cotyledonary leaf. In seedlings, the amounts of group A and Sg-6 saponins reduced 2.3- and 1.3-folds, respectively, while DDMP + B + E saponins increased 2.5-fold than those of mature seeds. Our findings show that the group A and Sg-6 saponins in mature seeds were degraded and/or translocated by germination whereas DDMP saponins were newly synthesized.

Balneotherapy and coenzyme Q10 in clinical and experimental medicine.

Balneotherapy or Spa therapy is used in neurological, cardiovascular, musculoskeletal, dermatological and gynecological diseases, in infertility as well as in metabolic disturbances. Beneficial effects of balneotherapy at the metabolic level is not fully understood. Authors have documented enhancement of antioxidants concentrations (coenzyme Q10- CoQ(10-OX) and alpha-tocopherol) of women with gynecological diseases by treatment with natural mineral water (Spa Lucky balneotherapy, Slovakia). In an experiment with rats, drinking of Spa Lucky mineral water decreased oxidative stress and enhanced concentrations of antioxidants CoQ(9-OX), CoQ(10-OX) in the myocardium, and alpha-tocopherol in uterus, ovaries and myocardium. Drinking of Spa Lucky water by rats stimulated myocardial mitochondrial respiration and energy production, and diminished skeletal muscle mitochondrial function. Simultaneous ingestion of coenzyme Q10 with drinking spa water returned mitochondrial parameters to the values of the control group. This pilot study helps explain the role of antioxidants, oxidative stress and mitochondrial energy production in beneficial effects of Spa Lucky balneotherapy.

Antioxidant, oxidative DNA damage protective and antimicrobial activities of the plant Trigonella foenum-graecum.

BACKGROUND: The plant Trigonella foenum-gracecum (TFG) is used as antidiabetic and diuretic. In order to ascertain antioxidant potential of leaf (early and mature) and seed of TFG, total phenolics, free radical scavenging assay, superoxide anion radical scavenging activity, reducing power, lipid peroxidation, ferric thiocyanate assay, hydroxyl radical scavenging activity and DNA damage protective activities were determined. The study was further carried out to assay the antimicrobial activity and HPLC analysis of plant parts. RESULTS: Ethanol extracts of leaf (early and mature) exhibited a high content of phenolics (54.79 and 41.28 g kg(-1) GAE) when it was compared with seed extract (23.85 g kg(-1) GAE). Results showed that mature TFG leaf extract had the lowest IC50 for the free radical scavenging assay (IC50 = 2.23 mg mL(-1)), superoxide anion radical scavenging activity (IC50 = 2.71 mg mL(-1)), hydroxyl radical scavenging activity (IC50 = 17.30 mg mL(-1)) and highest reducing power (10.14 ascorbic acid equivalents mL(-1)). However, the ethanol seed extract showed the maximum inhibition of lipid peroxidation and the ferric thiocyanate assay. Mature leaf also showed the maximum DNA damage protection activity and higher concentration of phytochemicals. CONCLUSION: The results showed that the mature TFG leaf had a higher antioxidant activity, which may be due to the presence of total phenolics. It may be used in herbal drugs or as a nutritional supplement.
