The discovery of ligands that bind specifically to a targeted protein benefits from the development of generic assays for high-throughput screening of a library of chemicals. Protein powder diffraction (PPD) has been proposed as a potential method for use as a structure-based assay for high-throughput screening applications. Building on this effort, powder samples of bound/unbound states of sol...

This study aims to evaluate the effects of supplementing golden apple snail (Pomacea canaliculata) eggs powder (EP) in the diet as a source of natural carotenoids on survival, pigmentation and antioxidant activity of Blood parrot. A total of 90 fish were divided into three treatment groups with three replicates per treatment. Blood parrot were fed with diets containing 0 (control), 5 % (EP 5 %)...

The aim of this study was to determine the feasibility of producing Nigella sativa powder under a foam mat drying technique. A central, composite design of experiments was used to optimize the drying condition and compare the solubility, the antioxidant and mineral content of roasted Nigella sativa, and the foam mat dried Nigella sativa powder. Foams were prepared from Nigella sativa solution b...

Inexpensive and non-intrusive marking methods are essential to track natural behavior of insects for biological experiments. An inexpensive, easy to construct, and easy to install bee marking device is described in this paper. The device is mounted at the entrance of a standard honey bee Apis mellifera L. (Hymenoptera: Apidae) hive and is fitted with a removable tube that dispenses a powdered m...

It is well known that supercritical CO2 (SC-CO2) is very efficient to remove neutral lipids from a variety of matrices, such as plant seeds [1]. The valuable, polar phospholipids (PL) remain behind, which is ascribed to their limited solubility in SC-CO2 [2]. Typically, they are extracted by adding a polar modifier such as methanol or ethanol to the supercritical fluid (SC-fluid) [2-4]. In a re...
