Extragonadal LH/hCG action-Not yet time to rewrite textbooks [PDF]
, 2007 Gonadotropins are indispensable in both sexes in the regulation of gonadal sex steroid production and gametogenesis. In addition to their well-established classical actions, numerous recent publications have indicated the presence and function of ...

Frontiers in Endocrinology, 2018 Minipuberty consists of activation of the hypothalamic-pituitary-gonadal (HPG) axis during the neonatal period, resulting in high gonadotropin and sex steroid levels, and occurs mainly in the first 3–6 months of life in both sexes. The rise in the levels

Bidirectional Interaction Between the Brain and Bone in Traumatic Brain Injury
Advanced Science, EarlyView.Traumatic brain injury (TBI) disrupts the blood–brain barrier and activates neuroimmune responses, causing metabolic disturbances and long‐term bone mass loss. Concurrent fractures accelerate healing and enhance osteogenesis but disrupt regulatory mechanisms, leading to altered bone dynamics and exacerbating neuroinflammation, complicating recovery ...

Advanced Science, EarlyView.Mammalian cloning via SCNT is limited by several epigenetic barriers. Kdm4d/Kdm5b overexpression plus TSA treatment overcomes epigenetic barriers during pre‐implantation development, while tetraploid complementation replaces defective extraembryonic lineages to bypass H3K27me3 imprinting loss to overcome epigenetic barriers in post‐implantation ...

Substance P regulates puberty onset and fertility in the female mouse [PDF]
, 2015 Puberty is a tightly regulated process that leads to reproductive capacity. Kiss1 neurons are crucial in this process by stimulating GnRH, yet how Kiss1 neurons are regulated remains unknown. Substance P (SP), an important neuropeptide in pain perception,

Advanced Science, EarlyView.Simulated microgravity induces distinct mitochondrial hyperactivation patterns‐elevated OXPHOS and MMP‐which accelerate meiosis without SAC failure but delays MTOC coalescence, leading to spindle defects and meiotic arrest. Prolonging M‐phase restores MTOC assembly and oocyte maturation.

Immunoreactive human chorionic gonadotropin and its free ß-subunit in serum and ascites of patients with malignant tumors [PDF]
, 1992 Human chorionic gonadotropin (hCG) is a clinically relevant marker of trophoblastic and nontrophoblastic malignancies. In the present studies, in addition to determining serum hCG, we investigated the presence and properties of hCG immunoreactivity in ...
