Knowledge, Attitude, and Practice Survey of Gastroparesis in Asia by Asian Neurogastroenterology and Motility Association [PDF]

open access: yes, 2021
Background/Aims Gastroparesis is identified as a subject that is understudied in Asia. The scientific committee of the Asian Neurogastroenterology and Motility Association performed a Knowledge, Attitude, and Practices survey on gastroparesis among ...

Motility Assay: Twitching Motility [PDF]

open access: yes, 2014
Twitching motility is a mode of solid surface translocation that occurs under humid conditions on semisolid or solid surfaces, is dependent on the presence of retractile type IV pili and is independent of the presence of a flagellum. Surface translocation via twitching motility is powered by the extension and retraction of type IV pili and can manifest

The Motility of Mollicutes [PDF]

open access: yesBiophysical Journal, 2003
Recent experiments show that the conformation of filament proteins play a role in the motility and morphology of many different types of bacteria. Conformational changes in the protein subunits may produce forces to drive propulsion and cell division. Here we present a molecular mechanism by which these forces can drive cell motion.

Regulation of the leading edge motility by PI (4,5)P2-dependent lipid microdomains [PDF]

open access: yes, 2005
The lipid second messenger PI(4,5)P2 modulates actin dynamics, and its local accumulation at plasmalemmal microdomains (rafts) might mediate regulation of protrusive motility.

Optical trapping reveals propulsion forces, power generation and motility efficiency of the unicellular parasites Trypanosoma brucei brucei [PDF]

open access: yes, 2014
Unicellular parasites have developed sophisticated swimming mechanisms to survive in a wide range of environments. Cell motility of African trypanosomes, parasites responsible for fatal illness in humans and animals, is crucial both in the insect vector ...

Effects of surface passivation on gliding motility assays [PDF]

open access: yes, 2010
In this study, we report differences in the observed gliding speed of microtubules dependent on the choice of bovine casein used as a surface passivator.

MOTILITY OF SPERMATOZOA [PDF]

open access: yesJournal of the American Medical Association, 1917
To the Editor: —In the Current Comment on "The Function of the Prostate" (The Journal, Feb. 17, 1917, p. 553), it is stated that "it has been noted that the spermatozoa are practically motionless while in the seminiferous tubules of the testis, but become actively motile in the vas deferens, or when mixed with prostatic secretion." The statement that

Plasma membrane Ca2+ ATPase 4 is required for sperm motility and male fertility [PDF]

open access: yes, 2004
Calcium and Ca(2+)-dependent signals play a crucial role in sperm motility and mammalian fertilization, but the molecules and mechanisms underlying these Ca(2+)-dependent pathways are incompletely understood. Here we show that homozygous male mice with a

Orbital magnetic resonance imaging is useful in age-related distance esotropia

open access: yesJournal of Optometry, 2018
Purpose: To describe findings for orbital magnetic resonance imaging (MRI) in patients with age-related distance esotropia (ARDE). Methods: We compared 31 orbital MRI from patients with ARDE (77 ± 7 SD years) with 2 control groups: 32 orbits from ...
