Effect of Propylparaben on In Vitro Maturation of Porcine Oocytes and Embryo Development
Environmental Toxicology, EarlyView.ABSTRACT Parabens are synthetic chemicals that, due to their antibacterial and fungicidal effects, are widely used as preservatives in food, cosmetics, and personal care products, such as shampoos, hair conditioners, body creams, soaps, deodorants, makeup, wet wipes, lotions, female hygiene products, and vaginal lubricants. Several years ago, they were

Meiosis in a living crane fly spermatocyte [Meiosis I]
, 2008 Presents the events of meiosis I in a living spermatocyte obtained from the testis of a crane-fly larva are recorded in this time-lapse sequence beginning at diakinesis through telophase to the near completion of cytokinesis following meiosis I ...

Yeast, EarlyView.We present cryoBN‐PAGE, a method that enables blue native polyacrylamide gel electrophoresis analysis of mitochondrial respiratory complexes and supercomplexes directly from whole yeast cells using cryogenic milling. This approach eliminates the need for mitochondrial isolation, reducing time and cost while preserving native protein complexes.

Reproductive Challenges of the Ageing Female: A Comprehensive Narrative Review
BJOG: An International Journal of Obstetrics &Gynaecology, EarlyView.ABSTRACT Changes in societal norms over the last few decades have resulted in novel family planning trends, notably delayed childbearing and increased maternal age at the birth of the first child. Despite advances in reproductive medicine, ageing poses significant challenges.

Meiosis in a living crane fly spermatocyte [Meiosis II]
, 2014 Presents the events of meiosis II in two living spermatocytes obtained from the testis of a crane-fly larva are viewed in polarized light and recorded in this time-lapse sequence beginning at prophase II through telophase II to the near completion of ...

The use of deidentified organ donor testes for research
Andrology, EarlyView.Abstract Our knowledge of testis development and function mainly comes from research using mammalian model organisms, primarily the mouse. However, there are integral differences between men and other mammalian species regarding cellular composition and expression profiles during fetal and post‐natal testis development and in the mature testis ...
