Endogenous hormonal status of embryogenic callus in cocos (Cocos nucifera L.) explants
(1997-01-01)
Endogenous hormonal concentrations of Z/ZR, IP/IPA, ABA and free IAA were determined in Cocos in vitro cultures during the period of embryogenic callus (calloid) formation and in selected tissues after 16 weeks grown on ...
Endogenous hormonal status of embryogenic callus in cocos (Cocos nucifera L.) explants
(1996-01-01)
The application of optimum concentrations of hormones according to specific culture stages plays an important role, especially in plants which are concerned lo be recalcitrant for propagation in vitro, like Cocos nucifera ...
Hormonal status of maize initial explants and of the embryogenic and non-embryogenic callus cultures derived from them as related to morphogenesis in vitro
(2001)
Endogenous hormone levels (indole-3-acetic acid [IAA], abscisic acid [ABA], gibberellins 1, 3 and 20 [GAs], zeatin/zeatin riboside [Z/ZR] and N6[Δ2-isopentenyl] adenine/N6[Δ2-isopentenyl] adenosine; [iP/iPA]) were analysed ...
How good is the levothyroxine replacement in primary hypothyroidism patients in Brazil? Data of a multicentre study
(Editrice Kurtis S R LMilanItália, 2013)
A hormonal misunderstanding in Acca sellowiana embryogenesis: levels of zygotic embryogenesis do not match those of somatic embryogenesis
(SPRINGERDORDRECHT, 2012-09)
Endogenous levels of IAA, ABA and four types of CKs were analyzed in zygotic and indirect (ISE) and direct somatic embryogenesis of Acca sellowiana. Zygotic and somatic embryos at different developmental stages were sampled ...
Influence of gender and endogenous sex steroids on catecholaminergic structures involved in physiological adaptation to hypoxia
(Pflugers Arch-Eur J Physiol, 1997)
Abstract Mechanisms underlying sex-related differ
ences in adaptation to high altitude were investigated by
assessing the turnover of dopamine and noradrenaline in
structures of the chemoafferent pathway, i.e. carotid
body ...
Metabolic basis for thyroid hormone liver preconditioning: Upregulation of AMP-activated protein kinase signaling
(2012)
The liver is a major organ responsible for most functions of cellular metabolism and a mediator between dietary and endogenous sources of energy for extrahepatic tissues. In this context, adenosine-monophosphate- (AMP-) ...
Maternally transferred thyroid hormones and life-history variation in birds
(Wiley, 2022)
In vertebrates, thyroid hormones (THs) play an important role in the regulation of growth, development, metabolism, photoperiodic responses and migration. Maternally transferred THs are important for normal early phase ...

2-methoxyestradiol inhibits progesterone-dependent tissue factor expression and activity in breast cancer cells
(2010)
2-Methoxyestradiol (2ME) is an endogenous metabolite of 17?-estradiol with antiangiogenic and antitumor properties, although its mechanisms of action remain unclear. Progestins in hormone replacement therapy increase the ...
