The impact of visible light component bands on polyphenols from red grape seed extract powder encapsulated in alginate-whey protein matrix.

Beads made of sodium alginate, whey protein concentrate, and red grape seed extract powder were exposed to white light and its red-orange, yellow-green-cyan, and cyan-blue-violet bands. The chemical analysis showed that encapsulation in the alginate-whey protein matrix protected polyphenols, flavonoids and cyanidin-3--glucoside when exposed to red-orange light. The reflectance spectra acquired from grape seed extract powder and grape seed extract beads were deconvoluted and anthocyanins-based moieties which contribute to the expression of bathochromic or hypsochromic effects were identified.

A review on cullin neddylation and strategies to identify its inhibitors for cancer therapy.

The cullin-RING E3 ligases (CRLs) are the biggest components of the E3 ubiquitin ligase protein family, and they represent an essential role in various diseases that occur because of abnormal activation, particularly in tumors development. Regulation of CRLs needs neddylation, a post-translational modification involving an enzymatic cascade that transfers small, ubiquitin-like NEDD8 protein to CRLs. Many previous studies have confirmed neddylation as an enticing target for anticancer drug discoveries, and few recent studies have also found a significant increase in advancement in protein neddylation, including preclinical and clinical target validation to discover the neddylation inhibitor compound.

The role of organo-zeolitic material in supporting phytoremediation of a copper mining waste dump.

The effect of applying organo-zeolitic (OZ) amendment in supporting phytoremediation of a copper mine waste dump, using a substrate obtained from Ľubietová, Central Slovakia, was studied. Three plant growth substrates were prepared: (i) the untreated substrate sample from the contaminated site (D-O), (ii) the contaminated sample treated with OZ material, with 82% D-O and 18% OZ (DO + OZ), (iii) the soil from a reference site (R). The largest amount of dry biomass was obtained from the DO + OZ sample.

Small-Angle Scattering from Nanoscale Fat Fractals.

Small-angle scattering (of neutrons, x-ray, or light; SAS) is considered to describe the structural characteristics of deterministic nanoscale fat fractals. We show that in the case of a polydisperse fractal system, with equal probability for any orientation, one obtains the fractal dimensions and scaling factors at each structural level. This is in agreement with general results deduced in the context of small-angle scattering analysis of a system of randomly oriented, non-interacting, nano-/micro-fractals.

Calcium- and ammonium ion-modification of zeolite amendments affects the metal-uptake of Hieracium piloselloides in a dose-dependent way.

The role of natural zeolite and of two types of modified zeolite (with ammonium and with calcium ions) in reducing the accumulation of ions of heavy metals in roots and leaves of Hieracium piloselloides grown on tailing ponds was investigated. The variation of the content of zeolite (5% w/w and 10% w/w) is another parameter that significantly and positively affects the accumulation of the metal ions in Hieracium piloselloides. The results showed that zeolite used as an amendment in the soil in tailing ponds significantly reduces the accumulation of heavy metal ions in Hieracium piloselloides.
