The Role of Gonadotropins and Growth Factor in Regulating Ras During Maturation in Cumulus–Oocyte Complexes of Pigs

Animals
Oocytes and cumulus cells undergo meiotic resumption and proliferation via gonadotropins and growth factors during maturation, and various small G proteins are activated when COCs undergo physiological changes.

Evo-devo of human adolescence: beyond disease models of early puberty [PDF]

, 2013
Despite substantial heritability in pubertal development, much variation remains to be explained, leaving room for the influence of environmental factors to adjust its phenotypic trajectory in the service of fitness goals.

The Maturity Premium

SSRN Electronic Journal, 2018
Abstract We show that firms with longer debt maturities earn risk premia not explained by unconditional factors. Embedding dynamic capital structure choices in an asset-pricing framework where the market price of risk evolves with the business cycle, we find that firms with long-term debt exhibit more countercyclical leverage.

Outcomes of Live Virus Vaccination in Patients With Vascular Anomalies Being Treated With Sirolimus

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Live vaccination in patients with vascular anomalies (VA) receiving sirolimus remains controversial due to immunosuppressive effects and theoretical risks. Procedure This single‐center retrospective study included patients with VA less than 4 years old at the start of sirolimus therapy who were incompletely vaccinated.

Abscission study during citrus fruit maturation in Corsica: unfavorable environmental conditions for fruit shedding [PDF]

, 2015
Citrus fruit development and ripening are complex processes involving physiological and biochemical changes that are under hormonal, nutritional and environmental control. One of the most evident phenomena in late maturation is shedding of ripe fruit.

To Mature or not to Mature: The Information Systems Conundrum

South African Computer Journal, 2013
Research has been done within the South African information technology (IT) industry over the last decade with regard to project management maturity (PMM) and the impact it has on delivering information systems (IS) projects successfully. The research was done to determine whether IS PMM per knowledge area has improved over the last decade.
