Expression of the neural cell adhesion NCAM in endocrine cells of the ovary [PDF]

open access: yes, 1991
In the adult mammalian ovary morphogenesis and differentiation processes are under hormonal control and, thus, occur in a highly regulated way during the sexual cycle.

T Cell Exhaustion in Cancer Immunotherapy: Heterogeneity, Mechanisms, and Therapeutic Opportunities

open access: yesAdvanced Science, EarlyView.
T cell exhaustion limits immunotherapy efficacy. This article delineates its progression from stem‐like to terminally exhausted states, governed by persistent antigen, transcription factors, epigenetics, and metabolism. It maps the exhaustion landscape in the TME and proposes integrated reversal strategies, providing a translational roadmap to overcome

From Skin Cells to Ovarian Follicles? [PDF]

open access: yesCell Cycle, 2006
Generating oocytes from cells derived from skin in vitro may provide a valuable model for identifying factors involved in germ cell formation and oocyte differentiation. In addition, the "oocytes" produced could potentially be useful for therapeutic cloning, and thus offer new possibilities for tissue therapy.

Structure of the ovaries of the Nimba otter shrew, Micropotamogale lamottei, and the Madagascar hedgehog tenrec, Echinops telfairi [PDF]

open access: yes, 2005
The otter shrews are members of the subfamily Potamogalinae within the family Tenrecidae. No description of the ovaries of any member of this subfamily has been published previously.

Tracking of [14C]Polystyrene Nanoplastics in Pregnant Mice

open access: yesAdvanced Science, EarlyView.
This study investigates [14C]polystyrene nanoplastic ([14C]PS) translocation in late‐stage pregnant mice after intranasal (0.5 mg of [14C]PS on GD12, GD14, and GD16, n = 6) and intravenous administration (1.5 mg of [14C]PS on GD16, n = 6). 14C‐radiolabel allows quantitative tracking of unmodified polystyrene nanoplastics.

Correlation between basal antral follicle count and mean ovarian diameter with ovarian responsiveness in art cycles

open access: yesMajallah-i Dānishgāh-i ̒Ulūm-i Pizishkī-i Bābul, 2006
BACKGROUND & OBJECTIVE: Since, ovarian response during assisted reproductive technology (ART) depends on ovarian reserve so it is important to evaluate ovarian reserve before the ART cycle.

Is in utero exposure to maternal socioeconomic disadvantage related to offspring ovarian reserve in adulthood?

open access: yesWomen's Midlife Health, 2018
Background Because the ovarian follicle pool is established in utero, adverse exposures during this period may be especially impactful on the size and health of the initial follicle endowment, potentially shaping trajectories of ovarian follicle loss and

An Ovarian Reserve Assessment Model Based on Anti-Müllerian Hormone Levels, Follicle-Stimulating Hormone Levels, and Age: Retrospective Cohort Study

open access: yesJournal of Medical Internet Research, 2020
BackgroundPreviously, we reported a model for assessing ovarian reserves using 4 predictors: anti-Müllerian hormone (AMH) level, antral follicle count (AFC), follicle-stimulating hormone (FSH) level, and female age.

Concentrated exosomes from menstrual blood-derived stromal cells improves ovarian activity in a rat model of premature ovarian insufficiency

open access: yesStem Cell Research & Therapy, 2021
Background Premature ovarian insufficiency (POI) is one of the major causes of infertility. We previously demonstrated that transplantation of menstrual blood-derived stromal cells (MenSCs) effectively improved ovarian function in a murine model of POI ...

Peripheral and central mechanisms involved in hormonal control of male and female reproduction [PDF]

open access: yes, 2016
Reproduction involves the integration of hormonal signals acting across multiple systems togenerate a synchronized physiological output. A critical component of reproduction is the luteinizinghormone (LH) surge, which is mediated by estradiol (E2) and ...
