Karyotypes and idiograms of sperm and pygmy sperm whales [PDF]

Hereditas, 2009
The somatic chromosomes of the sperm whale, Physeter catodon L. and the pygmy sperm whale, Kogia breviceps Blainville, were studied. The chromosome number of both species is 2n=42. The sperm and pygmy sperm whales are the only cetaceans, so far recorded, with a chromosome number deviating from 2n=44.

Functional parameters of spermatozoa obtained by a new selection device

FEBS Open Bio, EarlyView.
This study compares density gradient centrifugation and the LensHooke CA0™ device for sperm separation. DGC requires multiple steps, specialized equipment, and technical expertise. In contrast, the CA0 device offers key practical and methodological advantages, resulting in a faster, simpler, and more affordable sperm selection method.

Molecular Basis of Human Sperm Capacitation

Front. Cell Dev. Biol., 2018
In the early 1950s, Austin and Chang independently described the changes that are required for the sperm to fertilize oocytes in vivo. These changes were originally grouped under name of “capacitation” and were the first step in the development of in ...

Distribution of Glycoproteins on Feline Testicular Sperm, Epididymal Sperm and Ejaculated Sperm

Journal of Veterinary Medical Science, 2011
Glycoproteins (GPs) are known to be involved in the phenomenon of sperm maturation and capacitation. In the present study, we investigated the attachment of GPs on sperm cell membrane during the process of feline sperm maturation from testicular sperm to ejaculated sperm by using 8 FITC-labeled lectins.

Computerized Sperm Motility and Application of Sperm Cryopreservation [PDF]

Archives of Andrology, 1988
An objective method for measuring sperm motion characteristics was developed on an Intellect 100 Quantel Image Analysis System suitable for various image cytometric applications. It provided overall analysis of percent motility (% MS) as well as individual and mean measurements of motion characteristics, including vigor characteristics such as ...

Matrix: a complex amalgam of structures and functions in tumor microenvironment

FEBS Open Bio, EarlyView.
The matrix is a dynamic, intricate three‐dimensional mesh of biomolecules with both structural and functional properties. This review deals with the complexity of this ‘molecular amalgam’ in the tumor microenvironment and highlights its importance in the maintenance and evolution of tumors by describing certain matrix biomolecules, such as ...

Recommendations for the Use of Disease‐Modifying Antirheumatic Drugs in Pregnancy and Reproductive Health for Patients With Rheumatic Disease: A Scoping Review

Arthritis Care &Research, EarlyView.
Objective Autoimmune rheumatic diseases commonly affect individuals of childbearing age, with historically increased adverse pregnancy outcomes in this group. The advent of disease‐modifying antirheumatic drugs (DMARDs) has fostered more suitable conditions for pregnancy; however, this is accompanied by challenges in ensuring safe use in reproductive ...
