Hepatoblastoma with precocious puberty

Journal of Indian Association of Pediatric Surgeons, 2019
Hepatoblastoma (HB), a primary liver tumor of childhood, is often accompanied by raised levels of alpha-fetoprotein (α-FP). Rarely, the beta-human chorionic gonadotropin (β-hCG) levels may also be elevated, which can cause peripheral precocious puberty (PPP). We report a case of HB with precocious puberty wherein hormonal assays showed an increase in α-

Kisspeptin as a test of hypothalamic dysfunction in pubertal and reproductive disorders

Andrology, EarlyView.
Abstract The hypothalamic–pituitary–gonadal axis is regulated by the gonadotropin‐releasing hormone pulse generator in the hypothalamus. This is comprised of neurons that secrete kisspeptin in a pulsatile manner to stimulate the release of GnRH, and, in turn, downstream gonadotropins from the pituitary gland, and subsequently sex steroids and ...

Scaling, asymptotic scaling and Symanzik improvement. Deconfinement temperature in SU(2) pure gauge theory [PDF]

Phys.Rev. D49 (1994) 511-527, 1993
We report on a high statistics simulation of SU(2) pure gauge field theory at finite temperature, using Symanzik action. We determine the critical coupling for the deconfinement phase transition on lattices up to 8 x 24, using Finite Size Scaling techniques.
