Tritrichomonas fetus extracellular products decrease progressive motility of bull sperm
(Elsevier B.V., 2010-01-01)
Tritrichomonas fetus causes infertility and abortion in cattle; however, there is scarce information regarding the susceptibility of bovine sperm to this parasite. The objective of this study was to analyze in vitro the ...
Orbital Implants Insertion to Improve Ocular Prostheses Motility
(Lippincott Williams & Wilkins, 2010-05-01)
The objectives of this study were, through a literature review, to point the differences between orbital implants and their advantages and disadvantages, to evaluate prosthesis motility after orbital implants are inserted, ...
Calcineurin Regulates Progressive Motility Activation of Rhinella (Bufo) arenarum Sperm Through Dephosphorylation of PKC Substrates
(Wiley, 2014-10)
Animals with external fertilization, as amphibians, store their sperm in a quiescent state in the testis. When spermatozoa are released into natural fertilization media, the hypotonic shock triggers activation of sperm ...
Effect of motility on the transport of bacteria populations through a porous medium
(American Physical Society, 2019-01)
The role of activity on the hydrodynamic dispersion of bacteria in a model porous medium is studied by tracking thousands of bacteria in a microfluidic chip containing randomly placed pillars. We first evaluate the spreading ...
Ineffective esophageal motility and bolus clearance. A study with combined high-resolution manometry and impedance in asymptomatic controls and patients
(2020)
Background
The definition and relevance of ineffective esophageal motility (IEM) remains debated. Our aim was to determine motility patterns and symptoms associated with IEM defined as impaired bolus clearance.
Methods
To ...
Surfing of bacterial droplets: Bacillus subtilis sliding revisited
(National Academy of Sciences, 2017-10)
Hennes et al. (1) report on the collective slipping ofBacillus subtilis colonies across the agar surface, termed?colony surfing.? We read this article with great interest.However, we understand that specific points require ...

Evaluation of antidiarrhoeal effects of Psidium guajava L. (Myrtaceae) aqueous leaf extract in mice
(2006-12-01)
A crude aqueous extract of the leaves of the guava tree, Psidium guajava L. (Myrtaceae), were studied for antidiarrhoeal effects, to place one of its traditional medical uses. The extract induced a decrease in the propulsive ...
