Genetic and Morphological Analyses Demonstrate That Schizolecis guntheri (Siluriformes: Loricariidae) Is Likely to Be a Species Complex
(Frontiers Media Sa, 2018-03-02)
Schizolecis is a monotypic genus of Siluriformes widely distributed throughout isolated coastal drainages of southeastern Brazil. Previous studies have shown that fish groups found in isolated river basins tend to differentiate ...
Dynamics of Recovery of Physiological Parameters After a Small-Sided Game in Women Soccer Players
(Frontiers Media Sa, 2018-07-11)
Purpose: Training methods based on small-sided game (SSG) seem to promote physiological and tactical benefits for soccer players as they present characteristics more specific to the game. Thus, the main objective of the ...
Systemic Sympathoexcitation Was Associated with Paraventricular Hypothalamic Phosphorylation of Synaptic CaMKII alpha and MAPK/ErK
(Frontiers Media Sa, 2017-08-03)
Systemic administration of adrenergic agonist (Isoproterenol; ISOP) is known to facilitate cardiovascular changes associated with heart failure through an upregulation of cardiac toll-like receptor 4 (TLR4). Furthermore, ...
A Flow Cytometry Protocol to Estimate DNA Content in the Yellowtail Tetra Astyanax altiparanae
(Frontiers Media Sa, 2017-09-25)
The production of triploid yellowtail tetra Astyanax altiparanae is a key factor to obtain permanently sterile individuals by chromosome set manipulation. Flow cytometric analysis is the main tool for confirmation of the ...
Gene and Blood Analysis Reveal That Transfer from Brackish Water to Freshwater Is Less Stressful to the Silverside Odontesthes humensis
(Frontiers Media Sa, 2018-02-06)
Silversides are fish that inhabit marine coastal waters, coastal lagoons, and estuarine regions in southern South America. The freshwater (FW) silversides have the ability to tolerate salinity variations. Odontesthes ...
Hidden Nickel Deficiency? Nickel Fertilization via Soil Improves Nitrogen Metabolism and Grain Yield in Soybean Genotypes
(Frontiers Media Sa, 2018-05-08)
Nickel (Ni)-a component of urease and hydrogenase-was the latest nutrient to be recognized as an essential element for plants. However, to date there are no records of Ni deficiency for annual species cultivated under field ...
Additional Haptic Information Provided by Anchors Reduces Postural Sway in Young Adults Less Than Does Light Touch
(Frontiers Media Sa, 2018-06-05)
This study investigated the effect of adding haptic information to the control of posture, as well as comparing the effect of both the light touch (LT) and anchor system (AS) paradigms on postural sway. Additionally, it ...

(Frontiers Media Sa, 2017-12-12)
Hepsetidae is a small fish family with only the genus Hepsetus, with six described species distributed throughout the South, Central and Western regions of Africa, showing a close relationship with the Alestidae and some ...
Polymorphism in Mitochondrial Group I Introns among Cryptococcus neoformans and Cryptococcus gattii Genotypes and Its Association with Drug Susceptibility
(Frontiers Media Sa, 2018-02-06)
Cryptococcosis, one of the most important systemic mycosis in the world, is caused by different genotypes of Cryptococcus neoformans and Cryptococcus gattii, which differ in their ecology, epidemiology, and antifungal ...
Evaluation of the side effects of poly(epsilon-caprolactone) nanocapsules containing atrazine toward maize plants
(Frontiers Media Sa, 2015-10-21)
Poly(epsilon-caprolactone) (PCL) nanocapsules have been used as a carrier system for the herbicide atrazine, which is commonly applied to maize. We demonstrated previously that these atrazine containing polymeric nanocapsules ...
