Somatic cell reprogramming for Parkinson's disease treatment

open access: yesIbrain, 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

Optimizing outcomes in intrauterine insemination: A narrative synthesis of two decades of clinical research (2000–2024)

open access: yesInternational Journal of Gynecology &Obstetrics, EarlyView.
Abstract Intrauterine insemination (IUI) is a widely used first‐line fertility treatment, yet its success rates vary considerably. This review synthesizes evidence from peer‐reviewed studies published between 2000 and 2024, including randomized controlled trials, cohort and case–control studies, as well as systematic and narrative reviews identified ...

Luteal phase stimulation versus follicular phase stimulation in poor ovarian responders: A systematic review and a meta‐analysis

open access: yesInternational Journal of Gynecology &Obstetrics, EarlyView.
Abstract Background Poor ovarian response (POR) complicates a substantial proportion of in vitro fertilization (IVF) cycles, frequently causing cycle cancellation and suboptimal reproductive outcomes. Conventional follicular‐phase ovarian stimulation (FPOS) protocols often yield limited results, prompting the evaluation of alternative strategies such ...

Comparing the potential effects of fresh and frozen nerve extracts of Holothuria arguinensis on the oocyte maturation. [PDF]

open access: yesبوم‌شناسی آبزیان, 2019
Female sea cucumbers maintain their oocytes in meiosis prophase I, and their maturation only occurs just before spawning. A new methodology for inducing in vitro oocyte maturation in sea cucumbers is to expose them to their nerve extract which contains ...

Endometrial Stromal Cell Senescence: A Non‐Negligible Factor in Recurrent Pregnancy Loss

open access: yesiMetaMed, EarlyView.
As populations age, links between female reproductive aging and infertility are increasingly evident. Cellular senescence, characterized by near‐irreversible cell‐cycle arrest and accumulation of damage, can impair tissue function. In the endometrium, aberrant senescence of endometrial stromal cells (EnSCs) may compromise receptivity, hinder embryo ...

Organoids and organ‐on‐a‐chip models for investigating the pathophysiology of the human reproductive system

open access: yesInterdisciplinary Medicine, EarlyView.
Organoids and organ‐on‐a‐chips are advancing reproductive system research. In the female reproductive system, applications include cancer organoid models, placental chips, and hormone simulation models. For the male reproductive system, research focuses on drug resistance mechanisms, co‐culture platforms, and infertility studies. These refined in vitro

Antioxidant strategies to mitigate oxidative stress-induced cryodamage in oocytes

open access: yesFrigid Zone Medicine
Oocyte cryopreservation is an essential procedure in assisted reproductive technologies, aimed at preserving fertility, particularly for women undergoing IVF treatment or at risk of ovarian damage due to radiation, chemotherapy, or surgery.

Adult-onset hypothyroidism induces granulosa cell apoptosis and affects ovarian follicle development in rats

open access: yesFrontiers in Cell and Developmental Biology
IntroductionHypothyroidism is a common endocrine disorder in women, which could lead to ovulation disorders and infertility, however, the effects of adult-onset hypothyroidism on ovarian development and gene expression characteristics need further study ...

Noncanonical Nucleotides in the Genome Around the Maternal‐Zygotic Transition

open access: yesJournal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
In this paper, Kazzazi et al. provide a comprehensive review of the dynamics of nonconventional nucleotides in the genome during early developmental stages, hypothesizing a potential role for these nucleotides in the activation of the zygotic genome. ABSTRACT From the very moment of fertilization and throughout development, the cells of animal embryos ...
