Metalloceneincorporated Hybrid Singly N-Methyl N-Confused Calixphyrins: Synthesis, Characterization, Protonation and Deprotonation Studies.

Rational design and isolation of two hitherto unknown highly stable single conformer of ferrocene incorporated meso-aryl substituted singly N-methyl N-confused-calixphyrins have been achieved in quantitative yields. The solid-state crystal structure reveals the obvious trans-geometry for the meso-protons with the possibility for both the macrocycles to exist either racemic or enantiomer forms. However, thorough solution-state spectroscopic characterization strongly concludes the experimental isolation of a single isomer for both the macrocycles.

Efficacy of a functional food ingredient from Roxb. Cheesman peel in reducing the severity of ulcerative colitis in a murine model.

Ulcerative colitis is a recurrent inflammatory illness of the colon with an elevated risk of developing colon cancer. The drugs presently used to treat UC cause adverse effects and are limited to symptomatic treatments. To overcome these constraints, naturally derived novel alternative therapies are being tested.

Concentrates from tender coconut water and coconut testa beneficially modulates tissue lipid profiles in high-fat fed rats.

Unlabelled: The present study involved feeding of tender coconut water concentrate (TCW) and testa phenolic concentrate (PHE) to high fat fed animals. Analysis of serum showed increased HDL-C in concentrates treated group and therefore higher protection against atherogenesis compared to high fat fed group. Lesser fecal fat content and higher level of liver cholesterol were observed in high fat fed group, treatments with TCW and PHE ameliorated significantly.

Impact of phenolic concentrate from tender coconut water and coconut testa on high fat cholesterol fed C57BL6 mice.

Coconut testa and tender coconut water (TCW) are by-products of coconut processing industries which are rich in natural phytonutrients, if not exploited properly it may add up to environmental pollution. In the current study, phenolic concentrate (PHE) from coconut testa and tender coconut water (TCW) concentrates were examined for their effect on high fat fed C57BL/6 mice at the level of 50 & 100 mg and 500 & 1000 mg/kg body weight respectively. Results showed increasing body weight in high fat fed animals when compared to starch fed control (ND/SFD) group.

Immunoadjuvant and Humoral Immune Responses of Garlic ( L.) Lectins upon Systemic and Mucosal Administration in BALB/c Mice.

Dietary food components have the ability to affect immune function; following absorption, specifically orally ingested dietary food containing lectins can systemically modulate the immune cells and affect the response to self- and co-administered food antigens. The mannose-binding lectins from garlic ( agglutinins; ASAs) were identified as immunodulatory proteins in vitro. The objective of the present study was to assess the immunogenicity and adjuvanticity of garlic agglutinins and to evaluate whether they have adjuvant properties in vivo for a weak antigen ovalbumin (OVA).

Monitoring bioaccessibility of iron and zinc in pearl millet grain after sequential milling.

Unlabelled: The present study was to understand the effect of sequential milling on the distribution of inhibitory factors and their relation to iron-zinc bioaccessibility in the two pearl millet cultivars differing in grain shape and size. The studies revealed that the yield of decorticated grain and bran fractions differed between the cultivars. The initial bran fractions had lower iron content, which increased on increase of decortication duration (2.

Increase in awareness of consumers and demand has led to the development of various fibre rich food products from different fiber source. In the present work novel roller milled fenugreek fiber rich fraction (FFRF) rich in galactomannans was used for the development of high fiber . Farinograph water absorption and dough stability increased with increase in the addition of FFRF in blends.

N-Glycoprofiling of immunoglobulin G and lactoferrin with site-specificity from goat milk using RP-UHPLC MS/MS.

Glycans present in glycoproteins are structurally diverse and contribute to the carbohydrate pool of the milk. Goat milk is a leading non-bovine milk source, wherein glycan diversity of several glycoproteins remains unexplored. Herein, site-specific N-glycoprofiling of two major glycoproteins - immunoglobulin G (IgG) and lactoferrin (Lf) from goat milk was performed through RP-UHPLC Q-Tof MS/MS approach.

Biosynthesis and regulation of anthocyanin pathway genes.

Their scope has expanded dramatically in the past decade, making anthocyanin control, influx, and outflow regulation fascinating for many researchers.

Valorization of coffee leaves as a potential agri-food resource: bio-active compounds, applications and future prospective.

This article intends to summarize all the up-to-date information on coffee leaves, rendering it to be used as a potential agri-food resource in the growing functional foods and pharma industries. Coffee leaves have been processed for herbal tea and ethno-medicine since centuries in the parts of the world where coffee is grown traditionally. Currently, interest in the valorisation of coffee leaves for its application in the food industry is proliferating and the research related to it is scanty and, therefore, worthwhile to congregate.

Volatile organic compounds involved in the communication of microalgae-bacterial association extracted through Headspace-Solid phase microextraction and confirmed using gas chromatography-mass spectrophotometry.

In the present study, bacterial mixture (Rhizobium and Agrobacterium) and axenic Chlorella were cultivated individually, in a mixed (co-cultured) form, and through headspace connections to study volatile organic compounds (VOCs) profile and their effect on growth. Results indicated that VOCs produced by the axenic microalgae and microalgae co-cultured with bacteria were significantly different. Axenic Chlorella predominantly produced a flavouring organic compound 2-pentadecanone (69.

Crocetin exerts hypocholesterolemic effect by inducing LDLR and inhibiting PCSK9 and Sortilin in HepG2 cells.

Proprotein convertase subtilisin/kexin type 9 (PCSK9) is an important post-transcriptional regulator of plasma levels of low-density lipoprotein cholesterol (LDL-C). Inhibition of PCSK9 has emerged as an attractive strategy in recent years to combat hypercholesterolemia stimulating the search for PCSK9 inhibitors. The carotenoid crocetin exhibits hypocholesterolemic effect.

Lactucaxanthin Regulates the Cascade of Retinal Oxidative Stress, Endoplasmic Reticulum Stress and Inflammatory Signaling in Diabetic Rats.

Purpose: The purpose of this study is to investigate the protective mechanism of lactucaxanthin against retinal angiogenesis in diabetic retinopathy.

Methods: Streptozotocin-induced diabetic rats were orally gavaged with either lactucaxanthin or lutein (n=12/group) for 8 weeks. Serum and retina collected from euthanized rats were subjected to assess oxidative stress, ER stress and inflammatory response.

Prevalence of polymyxin resistance through the food chain, the global crisis.

Antimicrobial resistance is one of the vital challenges facing global health today. Multi-drug resistant (MDR) infections are often treated with the narrow-spectrum drugs, colistin (polymyxin E) or polymyxin B, which are last-resort antibiotics for human therapeutics that are effective against Gram-negative bacteria. Unfortunately, resistance to these polymyxins has occurred because of selective pressure caused by the inappropriate use of those antibiotics, especially in farming.

microRNAs in cancer chemoresistance: The sword and the shield.

Cancer is a multifactorial disease and one of the leading causes of mortality worldwide. Cancer cells develop multiple strategies to reduce drug sensitivity and eventually lead to chemoresistance. Chemoresistance is initiated either by intrinsic factors or due to the prolonged use of chemotherapeutics as acquired resistance.
