Improvement in quality of cryopreserved human spermatozoa by swim‐up before freezing [PDF]

International Journal of Andrology, 1994
SummarySelecting a population of spermatozoa by the swim‐up technique yields, after freezing and thawing, a population of cells that contains proportionally more spermatozoa which are morphologically normal, fewer spermatozoa with damaged tail membranes, and a greater percentage of progressively motile spermatozoa with greater velocities and amplitudes

Additional Hyaluronic Acid Binding Selection Decreased Sperm DNA Damage after Conventional Semen Preparation in Infertile Patient with Abnormal Semen Analysis

Siriraj Medical Journal, 2018
Objective: To study the benefit of combining conventional sperm preparation methods with hyaluronic acid binding in selecting spermatozoa with less DNA damage in infertile patients with abnormal semen analysis. Methods: Forty-six semen samples obtained

Mindfulness training combined with cold water immersion effects on mood and perception of executive functioning in middle-aged and older adults: a pilot study

Frontiers in Public Health
BackgroundAge-related cognitive decline typically begins during middle age and persists into old age. In parallel, mood (and, in particular, anxiety and depression) can be a significant predictor of neurodegenerative pathologies.

Venetoclax‐Based Therapy as a Bridge to Hematopoietic Stem Cell Transplantation in Relapsed or Refractory Pediatric Acute Leukemia

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Relapsed and/or refractory (R/R) pediatric acute leukemia carries a dismal prognosis, largely driven by chemoresistance to conventional salvage therapy. The BH3‐mimetic venetoclax, combined with chemotherapy or hypomethylating agents, has demonstrated efficacy in small clinical trials.

Relationship between swim bladder morphology and hearing abilities--a case study on Asian and African cichlids.

PLoS ONE, 2012
BackgroundSeveral teleost species have evolved anterior extensions of the swim bladder which come close to or directly contact the inner ears. A few comparative studies have shown that these morphological specializations may enhance hearing abilities ...

EFFECT OF SWIM-UP AND GLASS WOOL TECHNIQUES, WITH ADDING ANTIOXIDANTS TO TRIS EXTENDER ON IMPROVING POST-CRYOPRESERVED SOME SEMEN ATTRIBUTES OF LOW SEMEN QUALITY FOR HOLSTEIN BULLS

The Iraqi Journal of Agricultural science, 2021
This study was conducted to investigate the effect of swim-up and glass wool as sperm separation techniques with adding vitamin E and superoxide dismutase (SOD) to Tris extender on improving some post-cryopreserved semen quality for Holstein bulls.

Residual tail twisting in ascidian larvae is stabilized by asymmetric myofibrils that resist bilateral symmetry restoration

FEBS Letters, EarlyView.
Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

Efficacy of the swim-up method in eliminating sperm with diminished maturity and aneuploidy [PDF]

Human Reproduction, 2003
We have previously shown that after 80% Percoll centrifugation there is an overall 2.7-fold reduction of sperm with chromosomal disomies and diploidies (3.2-fold and 2.0-fold respectively), and of sperm with diminished maturity as detected by cytoplasmic retention. The relationship between disomies and immature sperm was r = 0.7, suggesting that disomy
