A very rapid method for isolating bacterial photosynthetic reaction centers (RCs) of high purity and yield is described. A poly-histidine tag is engineered at the C-terminus of the RC M-subunit, allow...
A new methanogen was isolated from an anaerobic digester using pig slurry in South Korea. Only one strain, designated KOR-1, was characterized in detail. Cells of KOR-1 were straight or crooked rods, ...
We investigated the effects of the predominant lactic acid bacteria (LAB) on the fermentation characteristics and aerobic stability of total mixed ration (TMR) silage containing soybean curd residue (...
This study was performed to investigate the use of urinary catecholamines to monitor changes in the activity of the sympathetic nervous system and to determine the relationship of urinary cortisol and...
The present study identified the favorable conditions for isolation, enrichment and in vitro culture of highly purified, undifferentiated pig spermatogonial stem cell (SSC) lines that proliferate for ...
Morphological, mitochondrial DNA, and single-copy nuclear DNA differences show that the tropical sea urchin Echinometra mathaei is composed of at least four independent gene pools. Evolutionary di...
In marine species, high dispersal is often associated with only mild genetic differentiation over large spatial scales. Despite this generalization, there are numerous reasons for the accumulation o...
Robust estimates of dispersal are critical for understanding population dynamics and local adaptation, as well as for successful spatial management. Genetic isolation by distance patterns hold clues ...
We have investigated the mechanical response of a magnetically shielded room that hosts a magnetoencephalography system that is subject to external vibrations. This is a superconducting quantum interf...
Natural products are organic molecules derived from plants, animals, or microorganisms, and represent the starting point for most of the anti-infective and anti-cancer drugs on the market today. Until...
Pocillopora is one of the most abundant and widely distributed coral genera, with a geographic range spanning the entire tropical Pacific and Indian Oceans as well as the Red Sea and Arabian Gulf. Acr...
The objective of this study was to establish the optimum protocol for the isolation and culture of porcine muscle satellite cells. Mononuclear muscle satellite cells are a kind of adult stem cell, whi...
Dissimilatory Fe(III) and Mn(IV) reduction is an anaerobic respiratory process common to many environments. A large number of bacteria that utilize these metals as terminal electron acceptors have bee...
In this study, a transition state analogue (TSA) approach was employed for the isolation of catalytic antibodies with esterase or amidase activity. The TSA used in this study, phosphonamidate, mimics ...
Whey proteins are an important constituent of milk, especially whey from cheese manufacture and have many valuable functional properties such as foaming and emulsifying ability or gel formation. Some ...
