In vitro method for predicting the bioavailability of iron from Bathua (Chenopodium album) and Fenugreek (Trigonella foenum graecum) leaves in Indian cookies

This study was considered to determine the nutritional composition and in vitro bioavailability of iron of the prepared food products. The in vitro bioavailability of iron was determined in fresh and dehydrated bathua (Chenopodium album) and methi (Trigonella foenum graecum) leaves (in the ratio of 1:1) and their based product i.e. Indian cookies (paratha and laddoo) by using thiocynate method at pH 1.35 and 7.5, using pepsin. At pH 1.35 the soluble iron and ionizable iron were higher than pH 7.5. when pH was increased from 1.35-7.5 there was decreasing trend soluble as well as ionizable iron contents. There was highly significant (F< 0.05) difference between the control and treatments of products indicating that the addition of 20% of fresh and dehydrated leaves of bathua and methi improved the overall acceptability of products. The total iron content was found 11.69mg/100g in paratha incorporated with fresh GLVs whereas in vitro bioavailability of iron was found 2.16mg/100g in paratha. The total iron content was found 15.16mg/100g in laddoo incorporated with dehydrated GLVs whereas in vitro bioavailability of iron was found 2.78mg/100g in laddoo

Biocomposting of extracted peppermint plant residue (Mentha piperita) using red worm, Eisenia fetida and its effect on the growth of Vigna mungo (Urad)

The study on biocomposting of extracted peppermint plant residue, Mentha piperita using red worms, Eisenia fetida on the growth of Vigna mungo (Urad) showed that the worms transformed 1:3 waste: dung medium into bio-compost one week earlier from 1:1 and two weeks earlier from 3:1 media. Rate of reproduction of worms was recorded 2.5 times faster in 1:3 medium than that of 3:1 and the number of earthworms was counted 2.09 times more in 1:3 waste: dung medium than that of 3:1. It was noticed that the bio-compost transformed from 1:3waste: dung medium when mixed with soil in 1:3 ratio and used as growing medium, showed the maximum shoot length of V. mungo (28.2 cm) and the minimum (24.3 cm) when it was transformed from 3:1 (waste: dung) medium and used in 1:1 ratio of vermicompost and soil. Results were discussed in the light of known data

Metal Nanowire Assisted Hollow Core Fiber Sensor for an Efficient Detection of Small Refractive Index Change of Measurand Liquid

In this article, a cost-effective hollow core fiber (HCF)-based refractive index (RI) sensor using surface plasmon resonance (SPR) is designed and demonstrated. The sensor consists of a metal nanowire inside an HCF along with the sensing medium of various refractive indices. SPR effect between polaritons and the guided core mode of designed HCF is exploited to enhance the sensing performance. A full vectorial finite element method (FEM) is used for the design and analyses of the sensing probes which exhibit very high sensitivities of 12,400 nm/RIU, 10560 nm/RIU, and 6400 nm/RIU for copper (Cu), gold (Au), and silver (Ag), respectively with a resolution of 1.61 × 10−6 RIU. Additionally, the influence of metal wire dimension is also investigated in this paper. The reported simple and low-cost sensor exhibits high sensitivity for liquid with refractive indices slightly higher than that of the dielectric tube, such as olive oil, turpentine, kerosene, chloroform, carbon tetrachloride, glycerol, and toluene

Self‐reported sleep quality is more closely associated with mental and physical health than chronotype and sleep duration in young adults: A multi‐instrument analysis

Sleep and circadian rhythms are considered to be important determinants of mental and physical health. Epidemiological studies have established the contribution of self‐reported sleep duration, sleep quality and chronotype to health outcomes. Mental health and sleep problems are more common in women and men are more likely to be evening types. Few studies have compared the relative strength of these contributions and few studies have assessed these contributions separately in men and women. Furthermore, sleep and circadian characteristics are typically assessed with a limited number of instruments and a narrow range of variables is considered, leaving the understanding of the relative contribution of different predictors somewhat fractionary. We compared sleep quality, sleep duration and chronotype as predictors for self‐reported mental and physical health and psychological characteristics in 410 men and 261 women aged 18 to 30. To ascertain that results were not dependent on the use of specific instruments we used a multitude of validated instruments including the Morningness‐Eveningness‐Questionnaire, Munich‐ChronoType‐Questionnaire, Pittsburgh‐Sleep‐Quality‐Index, British‐Sleep‐Survey, Karolinska‐Sleep‐Diary, Insomnia‐Severity‐Index, SF‐36‐Health Survey, General‐Health‐Questionnaire, Dutch‐Eating‐Behaviour‐Questionnaire, Big‐Five‐Inventory, Behaviour‐Inhibition‐System‐Behaviour‐Activation‐System, and the Positive‐Affect‐Negative‐Affect‐Schedule. Relative contributions of predictors were quantified as local effect sizes derived from multiple regression models. Across all questionnaires, sleep quality was the strongest independent predictor of health and in particular mental health and more so in women than in men. The effect of sleep duration and social jetlag was inconspicuous. A greater insight into the independent contributions of sleep quality and chronotype may aid the understanding of sleep‐health interactions in women and men

Antioxidant Capacity and Radical Scavenging Effect of Polyphenol Rich Mallotus philippenensis

Mallotus philippinensis is an important source of molecules with strong antioxidant activity widely used medicinal plant. Previous studies have highlighted their anticestodal, antibacterial, wound healing activities, and so forth. So, present investigation was designed to evaluate the total antioxidant activity and radical scavenging effect of 50% ethanol fruit glandular hair extract (MPE) and its role on Human Erythrocytes. MPE was tested for phytochemical test followed by its HPLC analysis. Standard antioxidant assays like DPPH, ABTS, hydroxyl, superoxide radical, nitric oxide, and lipid peroxidation assay were determined along with total phenolic and flavonoids content. Results showed that MPE contains the presence of various phytochemicals, with high total phenolic and flavonoid content. HPLC analysis showed the presence of rottlerin, a polyphenolic compound in a very rich quantity. MPE exhibits significant strong scavenging activity on DPPH and ABTS assay. Reducing power showed dose dependent increase in concentration absorption compared to standard, Quercetin. Superoxide, hydroxyl radical, lipid peroxidation, nitric oxide assay showed a comparable scavenging activity compared to its standard. Our finding further provides evidence that Mallotus fruit extract is a potential natural source of antioxidants which have a protective role on human Erythrocytes exhibiting minimum hemolytic activity and this justified its uses in folklore medicines
