(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 ...
-
(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 ...
-
(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 ...
-
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 ...
-
(2013-04-08)The origin and maintenance of phenotypic variation has generated considerable interest among students of functional morphology, sexual selection and behavioral ecology. In particular, hybridization has been suggested as a ...
-
(2012-12-06)All complex organisms possess a nervous system which they use to monitor environmental and internal stimuli. In higher vertebrates, the nervous system is comprised of billions of cells which form highly plastic neural ...
-
(Texas A&M University, 2007-09-17)The MotA and MotB proteins of E. coli form a MotA4MotB2 complex. Proton flow through a transmembrane channel in the complex powers flagellar rotation. Protonation of Asp-32 of MotB within the channel is proposed to cause ...
-
(2016-01-13)During colon cancer development, epigenetic alterations contribute to the dysregulation of major cellular functions and signaling pathways. Recent evidence suggests that nutritionally chemoprotective components that influence ...
-
(Texas A&M University, 2006-08-16)Melatonin is rhythmically synthesized and released by the pineal gland and, in some species, retina during the night and regulates many physiological and behavioral processes in birds and mammals. Chick diencephalic ...
-
(2020-06-04)Very little is known about how tissues can regulate their size. In one possible mechanism, cells in a tissue secrete a factor that inhibits their proliferation, and as the tissue gets bigger, the concentration of the factor ...
-
(2010-10-12)The transportation of organisms in the ballast water of cargo ships has been recognized as a source of invasive species despite current control measures. Pathogenic bacteria in the ballast tank have been studied but the ...
-
(2009-05-15)In order to release progeny, bacteriophages must lyse the host cell by compromising the peptidoglycan layer. There are two known strategies of lysis: the holin-endolysin system and single gene lysis (SGL), which are dependent ...
