From Physiology to Bioheat Simulation: A Data‐Driven Framework for Core Temperature Initialization

Heat Transfer, EarlyView.
ABSTRACT Accurate initialization of core body temperature is a critical yet often overlooked component of bioheat transfer models, particularly when such models are applied to heterogeneous populations and real‐world environmental conditions. Conventional bioheat simulations typically rely on fixed or idealized core body temperature values derived from

Apoptosis is increased and cell proliferation is decreased in out-of-phase endometria from infertile and recurrent abortion patients

Reproductive Biology and Endocrinology, 2010
Background Various endometrial abnormalities have been associated with luteal phase deficiency: a significant dyssynchrony in the maturation of the glandular epithelium and the stroma and a prevalence of out-of-phase endometrial biopsy specimens.

Cross‐Regulation Between DNA Methylation and Circadian Clock Reprogramming in Ovarian Cancer: Mechanistic Insights, Biomarker Potential, and Therapeutic Implications

International Journal of Cancer, EarlyView.
ABSTRACT Early diagnosis remains challenging, recurrence rates remain high, and platinum resistance frequently develops in ovarian cancer (OC), collectively representing major barriers to long‐term patient survival. DNA methylation (DNAm), as a relatively stable yet dynamically modifiable epigenetic signature, can capture alterations in tumor states ...

The effect of leptin on luteal angiogenic factors during the luteal phase of the estrous cycle in goats

, 2014
Fibroblast growth factor 2 (FGF2), angiopoietin 1 (Ang1), and vascular endothelial growth factor (VEGF) are angiogenic factors implicated in the vascular development of the corpus luteum (CL).

Vascular dysfunction in women with recurrent pregnancy loss: Possible association with antiphospholipid antibodies

International Journal of Gynecology &Obstetrics, Volume 169, Issue 1, Page 206-214, April 2025.
Abstract Objective Antiphospholipid antibodies (aPL) are recognized to have a pivotal role in recurrent pregnancy loss (RPL) and cardiovascular disease. Therefore, we assessed the vascular function of women with RPL and examined the association with each type of aPL.

The effect of ovarian stimulation protocol on follicular asynchrony during in vitro fertilization – A retrospective cohort study

International Journal of Gynecology &Obstetrics, EarlyView.
Abstract Objective To examine the effect of controlled ovarian stimulation (COS) protocol on follicular synchrony in a subsequent in vitro fertilization (IVF) cycle in patients whose previous cycle was canceled due to asynchrony. Methods A single‐center retrospective‐cohort study (January 2018–March 2024), including women undergoing IVF who had: (1) a ...
