Structural Variation Sequencing of 26 Amniotic Fluid Samples With Partial Gene Duplications and Postnatal Follow‐Up of the Fetuses

open access: yesPrenatal Diagnosis, EarlyView.
ABSTRACT Objectives Partial gene duplications (PGDups) are a significant contributor to genetic disease. The precise genomic location and structure of PGDups are often unresolved using conventional methods, so prenatal diagnosis for PGDups is challenging, especially without ultrasound abnormalities.

Nanomaterials' Multigenerational Effects by Single and Joint Exposure in Non‐mammalian Models

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Nanotoxicology has mainly focused on single‐generation studies, leaving multigenerational toxicity underexplored. Having animal welfare recently gained importance, we aimed to provide the state‐of‐the‐art of knowledge about multigenerational effects in non‐mammalian models in the case of nanomaterials (NM) single and joint exposure to other ...

Diving Deeper Into Mechanisms of Acrylamide‐Induced Toxicity: RNA Sequencing Reveals Transcriptomic Alteration and Retrotransposon Expression in Drosophila melanogaster

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Given the inevitability of human and animal exposure to acrylamide, there is increasing concern regarding its potential health risks. While a number of molecular mechanisms have been proposed, the complexity of acrylamide toxicological pathways and interactions remains incompletely characterized.

The Comparison of HA Binding and Zeta Methods Efficiency in Selection of Sperm with Normal Morphology and Intact Chromatin

open access: yesمجله دانشکده پزشکی اصفهان, 2009
Background: Sperm selection for ICSI is based on morphology and motility, but these parameters may not relevant chromatin integrity. One of the sperm selection methods for ICSI is based on sperm functional characteristics.

Effect of Propylparaben on In Vitro Maturation of Porcine Oocytes and Embryo Development

open access: yesEnvironmental 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

Swim‐up method is superior to density gradient centrifugation for preserving sperm DNA integrity during sperm processing

open access: yesReproductive Medicine and Biology
Purpose This study aimed to evaluate the effects of swim‐up and density gradient centrifugation methods on sperm DNA fragmentation. Methods Nineteen normozoospermic patient samples with ≥100 × 106 motile sperms were included in this study.

Evaluation of Human Sperm Quality In Vitro—Purification of Motile Sperm and Subsequent Assessment of Potential Apoptotic Signs Beyond DNA Fragmentation

open access: yesBiomolecules
In our previous studies, OptiPrep and Percoll density gradients separated human motile sperm without DNA fragmentation from immotile sperm with DNA damage.

And then there was us Et puis nous sommes apparus

open access: yesJournal of the Royal Anthropological Institute, EarlyView.
In 1987, the academic conference ‘Origins and Dispersals of Modern Humans: Behavioural and Biological Perspectives’ was held in Cambridge, UK. Subsequently referred to as the ‘Human Revolution’ conference, this meeting brought together the most prominent academics working in the field of human origins, including archaeologists and palaeoanthropologists,

Comparative analysis of sperm preparation techniques on DNA fragmentation and clinical outcomes: a network meta-analysis

open access: yesFrontiers in Endocrinology
IntroductionElevated sperm DNA fragmentation negatively affects assisted reproductive technology outcomes. Although multiple sperm preparation techniques are used, existing evidence is largely limited to pairwise comparisons.
