Mesenchymal stem cells and their promise in reversing ovarian aging

open access: yesJournal of Ovarian Research
Ovarian aging is accompanied by a decline in the quantity and quality of follicles, leading to reduced fertility. Ovarian aging encompasses natural aging due to DNA damage, telomere attrition, and mitochondrial dysfunction, as well as a pathological ...

Effects of essential amino acids on phagostimulation and reproduction in adults of the Mediterranean fruit fly Efectos de amino ácidos esenciales en la fago‐estimulación y reproducción en adultos de la mosca de las frutas del Mediterráneo

open access: yesPhysiological Entomology, EarlyView.
The phagostimulation and reproductive effects of individual essential amino acids, without other nutrient except fructose, were investigated. Methionine, Arginine and Leucine display significantly higher phagostimulation strength than fructose. Arginine and Methionine showed a significant improvement in reproductive activity compared to other tested ...

Far‐field bioluminescent immune cell–mediated photodynamic therapy is limited by photon flux

open access: yesPhotochemistry and Photobiology, EarlyView.
Bioluminescent immune cell‐mediated photodynamic therapy uses tumor‐homing, luciferase‐expressing immune cells as internal light sources to activate photosensitizers in deep‐seated and/or micrometastatic tumors. Using both experiments and computational simulations, we find that this approach delivers insufficient far‐field energy to tumor cells to ...

Immunologic studies in patients with premature ovarian failure

open access: yes, 1988
Tests for a range of autoantibodies, and counts of lymphocytes, B cells, T cells, and T cell subsets were performed in 45 Chinese patients with premature ovarian failure and 45 age-matched normal control subjects.

Understanding extracellular vesicles in antiaging

open access: yesPeriodontology 2000, EarlyView.
Abstract Background Aging is a multifactorial process marked by gradual cellular dysregulation, regulated by hallmarks, including genomic instability, mitochondrial dysregulation, and chronic inflammation. Extracellular vesicles (EVs), especially exosomes, have emerged as pivotal mediators of cell‐to‐cell communication with potential roles in both ...

TMEM16A chloride channels in the female reproductive tract and their role in normal and dysfunctional pregnancy and labour

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend TMEM16A plays a pivotal role in setting the duration of the action potential plateau in human uterine smooth muscle. An increase in TMEM16A expression in labour underpins a lengthening of the plateau and this provides time for the contraction to become larger and longer, important for timely successful labour.

Ovarian surface epithelium stem cells: oogenesis in vitro?

open access: yesZdravniški Vestnik, 2007
Background: The dogma that the total number of follicles and oocytes available for reproduction are determined at birth, and that one follicle and one oocyte are recruited from the existing pool to mature in each menstrual cycle still persists.

Autoimmune premature ovarian failure: of mice and women

open access: yes, 1998
Autoimmunity is a well-established mechanism of premature ovarian failure and may be the dominant cause of reversible premature ovarian failure. Because of its strong analogy with the human disease, murine experimental post-thymectomy autoimmune ...

Intramuscular pathways of maladaptation in overtraining syndrome

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend The transition from adaptive overreaching to maladaptive overtraining and mechanisms through which excessive training load can lead to performance decline. Four interconnected pathophysiological domains are highlighted: neural fatigue, involving both central and peripheral components such as altered sensory feedback and reflex ...
