The Influence of Drosophila Spire and Myosin V During Mid‐Oogenesis Is Independent of Their Direct Interaction

open access: yesCytoskeleton, EarlyView.
ABSTRACT Cooperativity between cytoskeletal proteins is crucial for spatiotemporal coordination in biological processes, like oogenesis. In mammalian and Drosophila oogenesis, proper assembly and function of actin networks require coordination between actin assembly factors Spire and formins, as well as actin‐associated proteins like myosins and Rab ...

Meiotic behavior as a selection tool in silage corn breeding

open access: yesGenetics and Molecular Research, 2010
In breeding programs, commercial hybrids are frequently used as a source of inbred lines to obtain new hybrids. Considering that maize production is dependent on viable gametes, the selection of populations to obtain inbred lines with high meiotic stability could contribute to the formation of new silage corn hybrids adapted to specific region.

Embryonic development of the Mediterranean starfish Hacelia attenuata

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background Starfish play essential ecological roles as predators and ecosystem regulators; however, detailed developmental descriptions exist for only a handful of species, none of which are from the Mediterranean Sea. Results In this study, we provide the first full account of the development of the Mediterranean starfish Hacelia attenuata ...

Causal Association Between Lifestyle Behavior and Potential Risk Factors With Blepharoptosis

open access: yesEye &ENT Research, EarlyView.
ABSTRACT Background Blepharoptosis is among the most common disorders of eyelid malposition that may influence appearance and damage visual function, and both of these can have negative effects on the quality of life. Various types of blepharoptosis have been reported, including neurogenic, traumatic, congenital, mechanical, psychogenic, and myogenic ...

Protective Effects of Fenugreek and Stevia Extracts on Dexamethasone‐Induced Testicular Damage in a Rat Model

open access: yesFood Safety and Health, EarlyView.
Fenugreek and stevia extracts protect against dexamethasone‐induced testicular damage in male rats by enhancing antioxidant defenses, improving sperm quality, and restoring hormonal balance, highlighting their potential as natural therapeutics for preventing corticosteroid‐induced reproductive toxicity.

The mitochondrial DNA copy number and ovary‐related reproductive disorders: A bidirectional two‐sample Mendelian randomization study

open access: yesInternational Journal of Gynecology &Obstetrics, Volume 169, Issue 1, Page 112-120, April 2025.
Abstract Objective In the present study, a bidirectional two‐sample Mendelian randomization approach was utilized to explore potential causal relationships between mitochondrial DNA copy number (mtDNA‐CN) and ovary‐related reproductive disorders (ORRDs), including ovarian dysfunction, ovarian cyst, polycystic ovary syndrome (PCOS), premature ovarian ...

Variation of microsporogenesis in sexual, apomictic and recombinant plants of Poa pratensis L

open access: yesCaryologia, 2022
Apomixis is a rather widespread phenomenon in plants. It is defined as the asexual formation of a seed from the maternal tissues of the ovule, avoiding the processes of meiosis and fertilization.
