(2017-04-24)Thyroid hormones regulate essential physiological processes, including metabolism, reproduction, and growth. A key constituent of all thyroid hormones is iodine. To obtain and concentrate iodine, vertebrates utilize a ...
-
Endospore formation by Clostridium difficile is a vital part of the life cycle for this Gram-positive bacterium. During this process, the mothercell packages proteins into the developing endospore. However, the mechanisms ...
-
(1977)The purpose of this study was to investigate the cell-mediated activity of the facultative intracellular parasite, Listeria Monocytogenes, in the guinea pig. Special emphasis was placed upon the particular subcellular ...
-
(2021-03-11)Genetics, diet, and environment alter stereotypical cognitive and locomotive decline with age. In C. elegans males, dysregulated metabolism contributes to behavioral decline due to increases in neuromuscular excitability. ...
-
(Texas A&M University, 2007-04-25)In the course of our efforts to resolve Pi transport mechanisms in the model fungus Neurospora crassa we identified a null mutant, par-1, that displays enhanced Pi transport activity specifically under alkaline growth ...
-
(2014-09-08)Important neurological and psychiatric diseases, including Alzheimer disease, nicotine addiction, and schizophrenia, are influenced by nicotinic acetylcholine receptors (nAChRs). Understanding the structure and function ...
-
(1993)Protein extracts from Anabaena sp. strain PCC 7120 contain the site-specific DNA-binding proteins BifA and BifB. The bifA gene was recently cloned in our laboratory using a transcriptional interference strategy. When applied ...
-
Male Caenorhabditis elegans undergo a radical remodeling of their anal depressor during late larval stage 4. In both hermaphrodites and males, the larval anal depressor primarily functions as a defecation behavior. However, ...
-
(2023-08-02)The rise in shiftwork in the USA has come with associated health issues that plague the late-night employee. The results of these practices have led to an increase in metabolomic disease and the disruption of the circadian ...
-
(2009-05-15)Vertebrate photoreceptors are polarized cells that consist of a specialized sensory structure termed the outer segment required for phototransduction and an inner segment that contains the cellular organelles. Proteins ...
-
(2014-08-01)Cryptococcosis is one of the leading causes of the deaths among AIDS patients. The high mortality rates of cryptococcosis are mainly due to inadequate information of its major causative agent Cryptococcus neoformans and ...
-
(2012-04-23)Paramecium tetraurelia is a large, single-celled, ciliated protist. Short cell cycle times (4.5-5 hours) and manipulable Mendelian genetics have made it an attractive research species, particularly for developmental genetics ...
-
(2017-07-31)Escherichia coli senses a variety of chemoeffectors. The Tsr chemoreceptor is known to mediate attractant response to serine. Previously, serine was the only attractant described for Tsr. Recent work suggests Tsr senses ...
-
(2017-05-10)Infections caused by Clostridium difficile have increased steadily over the past several years. While studies on C. difficile virulence and physiology have been hindered, in the past, by lack of genetic approaches and ...
-
(2022-03-23)Cell fate decisions in eukaryotic organisms can be altered in response to small dose changes of transcription factors. Drosophila melanogaster sex determination is such an example. Sex-lethal (Sxl) is the master regulatory ...
-
Electron beam (eBeam) technology is commonly used to sterilize food and food ingredients to inactivate microbial pathogens. In eBeam processing, electrons are accelerated to the speed of light in a linear accelerator, ...
-
Antimicrobial Agents of the Burkholderia Genus and Those Produced by Burkholderia contaminans MS14 (2020-12-07)The increasing threat of antibiotic resistant pathogens is a major problem in the management of infectious diseases, making it imperative that new antibiotics to combat them are discovered and sourced. However, limiting ...
-
(2020-11-22)Analyzing electroencephalography (EEG) complexity could provide insight into neural connectivity and its relationships with attention-deficit/hyperactivity disorder (ADHD) symptoms. I calculated multiscale entropy (MSE) ...
-
(Texas A&M University, 2006-10-30)The ability of plants to not only detect but also adjust to their environment is crucial for their survival. The genes involved in photomorphogenesis â developmental changes in response to light â and their ...
-
(2018-01-02)Chloroplasts have to divide to maintain their numbers throughout cycles of cell division by binary fission and conduct photosynthesis and fulfill other metabolic functions that are essential to plant life. Chloroplast ...
