Evaluation of ram semen motility by a swim-up technique [PDF]
Reproduction, 1993 The turbidity formed as ram spermatozoa swam up into a clear medium was measured using a colorimeter and this was used as an objective index of sperm motility. Wavelengths of 470-475 nm yielded higher optical densities (OD) than did 520-640 nm. The recommended distance between the light beam and semen-medium interface, and operation temperature were 5 ...

Polar features in the flagellar propulsion of E. coli bacteria
, 2015 E. coli bacteria swim following a run and tumble pattern. In the run state all flagella join in a single helical bundle that propels the cell body along approximately straight paths.

The role of cross-training in swim-related injuries in master’s swimmers [PDF]
, 2019 Orthopedic injuries often interfere with Masters athletes’ pursuit of better performance and might place economic burden on these athletes. PURPOSE: We determined if the incidence of injuries increases with age and the economic burden associated with ...

On the distribution and swim pressure of run-and-tumble particles in confinement [PDF]
, 2015 The spatial and orientational distribution in a dilute active suspension of non-Brownian run-and-tumble spherical swimmers confined between two planar hard walls is calculated theoretically. Using a kinetic model based on coupled bulk/surface probability

Modeling and Swimming Property Characterizations of Scaled-Up Helical Microswimmers [PDF]
IEEE/ASME Transactions on Mechatronics, 2014 Micro- and nanorobots capable of controlled propulsion at low Reynolds number are foreseen to change many aspects of medicine by enabling targeted diagnosis and therapy, and minimally invasive surgery. Several kinds of helical swimmers with different heads actuated by a rotating magnetic field have been proposed in prior works.

A synthetic benzoxazine dimer derivative targets c‐Myc to inhibit colorectal cancer progression
Molecular Oncology, EarlyView.Benzoxazine dimer derivatives bind to the bHLH‐LZ region of c‐Myc, disrupting c‐Myc/MAX complexes, which are evaluated from SAR analysis. This increases ubiquitination and reduces cellular c‐Myc. Impairing DNA repair mechanisms is shown through proteomic analysis.
