Oxidative stress under low oxygen conditions triggers hyperflagellation and motility in the Antarctic bacterium Pseudomonas extremaustralis
(Springer Tokyo, 2019-06)
Reactive oxygen species and nitrogen species (ROS and RNS), produced in a wide range of physiological process even under low oxygen availability, are among the main stressors found in the environment. Strategies developed ...
Getting to and away from the egg, an interplay between several sperm transport mechanisms and a complex oviduct physiology
(Elsevier Ireland, 2020-12-01)
In mammals, the architecture and physiology of the oviduct are very complex, and one long-lasting intriguing question is how spermatozoa are transported from the sperm reservoir in the isthmus to the oocyte surface. In ...
Insights into Stem Cell Factor chemotactic guidance of neural crest cells revealed by a real-time directionality-based assay
(Elsevier Gmbh, 2012-05)
The extracellular environment through which neural crest cells (NCCs) translocate and differentiate plays a crucial role in the determination of cell migration and homing. In the trunk, NCC-derived melanocyte precursor ...
Cannabidiol (Cbd) alters the functionality of neutrophils (pmn). implications in the refractory epilepsy treatment
(Molecular Diversity Preservation International, 2021-03)
Cannabidiol (CBD), a lipophilic cannabinoid compound without psychoactive effects, has emerged as adjuvant of anti‐epileptic drugs (AEDs) in the treatment of refractory epilepsy (RE), decreasing the severity and/or frequency ...
Identification of two different chemosensory pathways in representatives of the genus Halomonas
(BioMed Central, 2018-04)
Background: Species of the genus Halomonas are salt-tolerant organisms that have a versatile metabolism and can degrade a variety of xenobiotic compounds, utilizing them as their sole carbon source. In this study, we ...
Mutational Replacements at the "glycine Hinge" of the Escherichia coli Chemoreceptor Tsr Support a Signaling Role for the C-Helix Residue
(American Chemical Society, 2017-07)
Bacterial chemoreceptors are dimeric membrane proteins that transmit signals from a periplasmic ligand-binding domain to the interior of the cells. The highly conserved cytoplasmic domain consists of a long hairpin that ...
Time-course study of different innate immune mediators produced by ultraviolet irradiated skin. Comparative effects between short and daily versus harmful and imprudent UV- exposures
(Wiley, 2014-11)
The modulatory effects of solar ultraviolet radiation (UVR) on the immune system have been widely studied. As the skin is the main target of UVR, our purpose was to compare the impact of two contrasting ways to be exposed ...
Phenanthrene degradation and strategies to improve its bioavailability to microorganisms isolated from brackish sediments
(Elsevier, 2013-10)
Samborombón Bay, Argentina, is a highly productive area exposed to chronic contamination, including polycyclic aromatic hydrocarbons. Four phenanthrene-degrading strains were isolated from sediments collected in this area. ...
New insights into halophilic prokaryotes isolated from salting–ripening anchovies (Engraulis anchoita) process focused on histamine-degrading strains
(Springer Tokyo, 2020-08)
Salted and ripened fish foods are susceptible to cause histamine poisoning. The present study focuses on microbial histamine degradation from high salted fermented fishery products to deepen our understanding about this ...
Neurotrophic factor NT-3 displays a non-canonical cell guidance signaling function for cephalic neural crest cells
(Elsevier Gmbh, 2013-11)
Chemotactic cell migration is triggered by extracellular concentration gradients of molecules segregated by target fields. Neural crest cells (NCCs), paradigmatic as an accurately moving cell population, undergo wide ...
