Telomere lengths in human oocytes, cleavage stage embryos and blastocysts [PDF]

, 2010
Telomeres are repeated sequences that protect the ends of chromosomes and harbour DNA-repair proteins. Telomeres shorten during each cell division in the absence of telomerase.

Oocyte Maturation in Starfish

Cells, 2020
Oocyte maturation is a process that occurs in the ovaries, where an immature oocyte resumes meiosis to attain competence for normal fertilization after ovulation/spawning. In starfish, the hormone 1-methyladenine binds to an unidentified receptor on the plasma membrane of oocytes, inducing a conformational change in the heterotrimeric GTP-binding ...

Glial Versus Neuronal Na+/K+‐ATPase in Activity‐Evoked K+ Clearance and Their Sensitivity to Elevated Extracellular K+

Glia, EarlyView.
The glial Na+ pump regulates [K+]o during neuronal activity, and the neuronal version restores [K+]o to baseline. Spreading depression‐related rise of K+ does not cause SD propagation via suppression of Na+/K+‐ATPase or glutamate transport. ABSTRACT Neuronal activity in the central nervous system is associated with a [K+]o transient that is swiftly ...

Estradiol and luteinizing hormone concentrations in the follicular aspirate during ovum pickup as predictors of in vitro fertilization (IVF) outcome

Middle East Fertility Society Journal, 2017
Background: A relationship between ‘oocyte quality’ and follicular fluid hormones is expected, since its formation coincides with the ‘oocyte maturation’ phase.

Somatic cell reprogramming for Parkinson's disease treatment

Ibrain, Volume 11, Issue 1, Page 59-73, Spring 2025.
The fundamental purpose of cell reprogramming to treat Parkinson's disease is to generate dopaminergic neurons (DAN) and do transplantation. There are two ways to accomplish this. One method is to induce cells into induced DA neurons (iDAN) directly or to induce cells into induced pluripotent stem cells and ultimately into iDAN in vitro. Another option

Efficacy of hormone pre‐treatment before ART to improve reproductive outcomes in infertile women with endometriosis: Network meta‐analysis of randomized controlled trials

International Journal of Gynecology &Obstetrics, EarlyView.
Abstract Background Hormone pre‐treatment is still used before assisted reproductive technique (ART) in endometriotic women, but evidence supporting this recommendation is conflicting. Objectives To evaluate whether hormone pre‐treatment with gonadotropin‐releasing hormone (GnRH) agonists or progestogens could improve fertility in women with ...

Pregnancy via Testicular Sperm Extraction for Anejaculation After Neuroblastoma Surgery

IJU Case Reports, EarlyView.
ABSTRACT Background Surgical treatment of a neuroblastoma, a malignant tumor of the sympathetic nervous system, may result in ejaculatory disorder. There are no reports examining ejaculation disorders after neuroblastoma surgery. Case Presentation The patient was a 31‐year‐old Japanese male who had undergone surgery for neuroblastoma of the abdomen at ...

Mitochondrial dysfunction: Related diseases, influencing factors, and detection

Interdisciplinary Medicine, EarlyView.
Mitochondrial dysfunction is implicated in the pathogenesis of numerous diseases, including neurological disorders, cancers, and cardiovascular conditions, through mechanisms such as mitochondrial DNA mutations, dysregulation of mitochondrial network dynamics, and impaired mitophagy.
