Pregnancy Outcomes and Postnatal Health From Transferred Mosaic Embryos Following Preimplantation Genetic Testing for Aneuploidy

open access: yesiNew Medicine, EarlyView.
This illustration synthesizes the methods and conclusion of this study, demonstrating that the transfer of mosaic embryos following reimplantation genetic testing for aneuploidy does not increase the risk to postnatal health. ABSTRACT Next‐generation sequencing (NGS) has increased the detection of mosaic embryos during preimplantation genetic testing ...

Meiosis in elephant grass (Pennisetum purpureum), pearl millet (Pennisetum glaucum) (Poaceae, Poales) and their interspecific hybrids

open access: yesGenetics and Molecular Biology, 2006
The cultivated and sexually compatible species Pennisetum purpureum (elephant grass, 2n = 4x = 28) and Pennisetum glaucum (pearl millet, 2n = 2x = 14) can undergo hybridization which favors the amplification of their genetic background and the ...

Recurrence of multiple meiotic abnormalities in maize genotypes from the same origin and their influence on productivity. [PDF]

open access: yes, 2018
The frequency of meiotic abnormalities among single-, double- and three-way cross experimental hybrids and their parental inbred lines is studied. Among the sixteen inbred lines examined, fifteen originated from populations developed at the National ...

Testicular histopathology and its association with germ cell numbers, serum concentrations of reproductive hormones, and semen quality

open access: yesAndrology, EarlyView.
Abstract Background It is well‐established that spermatogenesis, semen quality, and reproductive hormones are interlinked. It is, however, less well‐described how various specific testicular histopathologies are linked to reproductive hormones and semen quality.

Mammalian telomeres and their partnership with lamins [PDF]

open access: yes, 2016
Chromosome ends are complex structures, which require a panel of factors for their elongation, replication, and protection. We describe here the mechanics of mammalian telomeres, dynamics and maintainance in relation to lamins.

The role of iron in normal and impaired testicular function

open access: yesAndrology, EarlyView.
Abstract Iron plays a critical role in testicular physiology, impacting spermatogenesis, testosterone production, and overall testicular function. Iron homeostasis is maintained through systemic and cellular regulatory mechanisms, including hepcidin‐mediated systemic iron control and the iron‐responsive element/iron regulatory protein (IRE/IRP) system ...

Cytogenetic analysis of hybrids derived from wheat and Tritipyrum using conventional staining and genomic in situ hybridization

open access: yesBiologia Plantarum, 2010
The new salt tolerant cereal, Tritipyrum (2n=6x=42, AABBEbEb) offers potential to introduce desirable characters for wheat improvements. This study was aimed to generate a segregating population from Iranian local wheat cultivars (2n=6x=42, AABBDD) and ...

Cytology of some Iranian Stipa (Poaceae) species and populations [PDF]

open access: yes, 2006
Meiotic studies were performed on 16 populations of 13 Stipa species concerning polyploidy level, chiasma frequency and distribution, chromosome association and segregation.

An introspective update on the influence of miRNAs in breast carcinoma and neuroblastoma chemoresistance [PDF]

open access: yes, 2014
Chemoresistance to conventional cytotoxic drugsmay occur in any type of cancer and this can either be inherent or develop through time. Studies have linked this acquired resistance to the abnormal expression of microRNAs (miRNAs) that normally silence ...

CRISPR/Cas9‐mediated Genome‐editing Reveals 10 Testis‐enriched Genes and One Non‐testis‐enriched Gene are Dispensable for Male Fecundity in Mice

open access: yesAndrology, EarlyView.
ABSTRACT Background More than 1000 genes have been identified as predominantly expressed in the human testis. Advances in gene editing technologies have enabled the rapid and efficient generation of genetically engineered mice. This approach facilitates the screening of genes essential for spermatogenesis by analyzing knockout mouse models.
