Nonalcoholic Palm Nectar from Cocos nucifera (NPNC), a bio-refresher obtained from the juvenile inflorescence of coconut palm; is prominent as a nutritional health drink. The aim of this study was to investigate the nutritional and medicinal properties of NPNC and its products; sugar (NPNCS) and honey (NPNCH). The collected samples were subjected to physicochemical evaluations such as pH, Titrable Acidity, Total Soluble Solids, and Ash value, using standard techniques. The analysis revealed the suitability of NPNC as a natural health drink over conventionally available beverage. The elemental compositions of the samples were determined by using Inductive Coupled Plasma-Atomic Emission Spectrometry and demonstrated that NPNCH is enriched with iron and NPNCS with calcium. Vitamin C present in the samples was determined by using 2,6-Dichlorophenol indophenol redox titration method. Hydrolysable polyphenols, tannins, and flavonoids are determined by Folin-Ciocalteu, by Folin-Denis's technique and by aluminium chloride colorimetric methods, respectively. In NPNC, the dominance of Vitamin C as antioxidant is observed. Diuretic activity of samples was determined by Lipschitz method, and the results revealed that NPNC exhibited significant diuretic activity, comparable with furosemide. Immunomodulatory activities of the samples were evaluated by using indirect hemagglutination test and by using delayed type hypersensitivity (DTH) response. NPNC, NPNCS, and NPNCH exhibited stimulatory effect on humoral and cell-mediated immunity, which is comparable with that of standard immunomodulator levamizole. Subacute toxicity studies of selected samples were done in Wistar rats and the results proved the boicompatibility of the samples without systemic toxic effects. PRACTICAL APPLICATIONS: The use of commercially available carbonated beverages and energy drinks in young adults are associated with negative health outcomes with increased incidence of diabetes, sleep disturbances, and dental problems. Even though, such complications are there, the energy drink industries have grown dramatically accounting for major percentage of market sale. Researchers are in search for natural health drinks with some medicinal value to avoid the negative impact on consumers' health. Nonalcoholic Palm Nectar from Cocos nucifera (NPNC) is considered as zero alcoholic natural health drink. The focus of this study is to reveal the potential medicinal properties of NPNC and its products; honey (NPNCH) and sugar (NPNCS). If the nutritional and medicinal values of the selected preparations from natural sources can be proved with scientific evidence, its ability to beat commercially available carbonated beverages and energy drinks with negative health consequences may get widespread acceptance.

Background Knowledge regarding differences in care for psoriatic patients is limited. The aim of this study was to investigate factors influencing prescription of systemic treatments for patients with psoriasis with a special focus on socioeconomic factors. Methods and findings This was a non-interventional, cross-sectional study, conducted in 18 Italian University and/or hospital centers with psoriasis-specialized units. Questionnaires evaluating demographic and socioeconomic characteristics we...

Among all the food-related nanoparticles consumed every day, silver nanoparticles (AgNPs) have become one of the most commonly utilized, because of their anti-microbial properties. Despite their common use, the effects of sub-lethal concentrations of AgNPs, especially on gut biofilms, have been poorly investigated. To address this issue, we investigated in vitro the proteomic response of a mono-species Escherichia coli gut biofilm to chronic and acute exposures in sub-lethal concentrations of Ag...

Reactive oxygen species (ROS) are physiologically involved in functions like sperm maturation, capacitation and acrosome reaction, but their excess is involved in male infertility. Antioxidants in seminal plasma (SP) are an important factor balancing physiologic and harmful ROS activities. In this study, we determined and compared the full profiles of the water- and fat-soluble antioxidants in SP and serum of 15 healthy fertile subjects (ranging between the ages of 35 and 42 years). Ejaculates w...

Nature has made nutritive products in such a way that it cannot be manufactured in laboratories or in mills. Coconut Neera is the natural sap of the mature coconut palms rich with all essential nutrients, minerals and vitamins for human health. Harvesting of Neera from the spadix of the palms without disturbing the physiology of the tree has a lot of potential at the industrial scale. However, the development of alcohol in the extracted sap during tapping by auto-fermentation has given a misnome...

(1) Background: Fungal metabolites such as haloanisoles (especially 2,4,6-tribromoanisole/ 2,4,6-TCA) are contaminants of cork and wood barrels, materials that are widely used in the wine industry. Thus, the accurate and timely detection of these substances is very important for this sector of beverage industry. (2) Methods: Potentiometry was used for the Bioelectric Recognition Assay (BERA)-based experimental approach, where changes in the electric properties of the Vero cells modified with ant...

Heavy alcohol consumption is an established risk factor for hypertension; the mechanism by which alcohol consumption impact blood pressure (BP) regulation remains unknown. We hypothesized that a genome-wide association study accounting for gene-alcohol consumption interaction for BP might identify additional BP loci and contribute to the understanding of alcohol-related BP regulation. We conducted a large two-stage investigation incorporating joint testing of main genetic effects and single nucl...

Abstract The anti-psoriatic efficacy of orally administered methotrexate loaded chitin nanogel (MCNG) was evaluated (two doses- 2.715 mg/kg and 5.143 mg/kg) and compared against orally administered methotrexate tablet MTX (5.143 mg/kg). MCNG at both dose levels of 2.715 mg/kg and 5.143 mg/kg exhibited significant anti-psoriatic activity which is very much comparable with MTX, caused normalization of histological features and inflammatory score associated with induced psoriasis. Biodistribution s...

Hepatosteatosis, a form of nonalcoholic fatty liver disease (NAFLD), is being increasingly recognized as a major health burden worldwide. Insulin resistance, dyslipidemia and imbalances in adipokine/cytokine interplay are reported to be involved in the onset and progression of this disease. Use of dietary nutraceuticals in prevention and treatment of NAFLD is emerging. Virgin coconut oil (VCO), a fermented product of fresh coconut kernel, has been shown to impede the development of hepatosteatos...

Abstract Methotrexate loaded chitin nanogel (MCNG) was formulated for its topical use in psoriasis. MCNG was characterized by DLS, TEM and FTIR. The MCNG particles were spherical in shape with size of 196 ± 14 nm, having surface charge of +9.21 ± 0.42 mv. MCNG exhibited greater swelling and drug release at acidic pH than neutral and alkaline conditions. The treatment with MCNG showed significant level of toxicity on HaCaT and THP-1 cells and was taken up well by HaCaT cells as revealed by fluore...
