Chromium (III) complexes and their relationship to the glucose tolerance factor : a thesis presented in partial fulfillment of the requirements for the degree of Master of Science in Chemistry at Massey University [PDF]
Two forms of the dinicotinate complex Cr(nic)2(H2O)3OH were formed which were yellow and blue, respectively. For the yellow form the nicotinic acid ligands were coordinated via the pyridine ring nitrogen atom but this complex was biologically inactive ...

A novel anticoagulant peptide from the Nori hydrolysate
A potent and novel anticoagulant peptide was enzymatically isolated from the edible seaweed Porphyra yezoensis (commercially known as Nori). The pepsin hydrolysate showed 35% degree of hydrolysis and exhibited higher anticoagulant activity than ...

Abstract Species can be difficult to circumscribe using morphology alone, and additional data can thus be useful for resolving challenging species complexes. Here we provide a case study of a South African orchid species complex which we resolved by analysing morphology, floral scent chemistry and molecular data.

Mechanism of the Enzymic Reduction of N_2: The Binding of Adenosine 5'-Triphosphate and Cyanide to the N_2-reducing System [PDF]
The in vitro reduction of N_2 is a complex process involving at least six different reactants: two proteins [1,2] for which the names azoferredoxin (AzoFd) and molybdoferredoxin (MoFd) have been proposed[3], an electron source, the electron acceptor, ATP[

Obtaining and Characteristic of the Autolysate of Lactic Acid Bacteria [PDF]
Fragments of bacterial peptidoglycan relating to compounds of the muropeptide series have high biological activity. They have an immunological effect, due to the fact that they are signals for immune receptors and, accordingly, their activators. In order

We assessed gallerimycin, galiomycin, and hemolin gene expression in Galleria mellonella whole larvae, hemocytes, and fat body at 4 and 24 h post‐injection of Candida albicans and silica beads. Higher gallerimycin and galiomycin expression in hemocytes signified their role in antimicrobial peptide synthesis.

Anti-inflammatory properties of ebselen in a model of sephadex-induced lung inflammation.
Ebselen (2-phenyl-1,2-benzisoselenazol-3(2H)-one), is a seleno-organic compound which protects tissues against oxidative stress. Furthermore, recent data has suggested that this compound possesses a range of anti-inflammatory properties.

When overexpressed in Staphylococcus aureus, the type I toxins SprA1 and SprA2 form membrane pores, with SprA1 creating stable pores and SprA2 forming transient ones. Both induce concomitant membrane depolarization, ATP release, and growth arrest, while only SprA1 causes membrane permeabilization due to its stable pore formation.

Summary Intake of glucosinolates through the consumption of cruciferous vegetables has been associated with numerous health benefits. In recent decades, glucosinolate glucoraphanin has gained a lot of attention, as its hydrolysis product (sulforaphane) is known to possess numerous health‐promoting benefits, including anti‐cancer and chemopreventive ...
