Novel mechanisms of growth hormone regulation: growth hormone-releasing peptides and ghrelin
(Associação Brasileira de Divulgação Científica, 2006-08-01)
Growth hormone secretion is classically modulated by two hypothalamic hormones, growth hormone-releasing hormone and somatostatin. A third pathway was proposed in the last decade, which involves the growth hormone ...
Cytological differentiation and cell wall involvement in the growth mechanisms of articulated laticifers in Tabernaemontana catharinensis A.DC. (Apocynaceae)
(2018-07-11)
The cellular mechanisms of laticifer growth are of particular interest in plant biology but are commonly neglected. Using transmission electron microscopy and immunocytochemical methods, we recorded cytological differentiation ...
Coalescence growth mechanism of inserted tin dioxide belts in polycrystalline SnO2-based ceramics
(Elsevier B.V., 2018-08-01)
SnO2-based varistors have been considered promising technological devices. However their practical application is usually stated as limited to high voltage circuits based on the high breakdown electric field exhibited by ...
SOCIAL-CONTROL OF GROWTH IN FISH
(Associação Brasileira de Divulgação Científica (ABRADIC), 1994-04-01)
This review concerns the phenomenon of heterogeneous growth (Het-G) in fish. Het-G is characterized by different growth rates between conspecifics. Although genetic determination on Het-G is recognized, grouping increases ...

OLIGOMER CHAIN LENGTH EFFECT ON THE NUCLEATION AND GROWTH MECHANISMS (NGM) OF POLYTHIOPHENE
(Sociedad Chilena de Química, 2009)
Nutrient regulation of somatic growth in teleost fish: The interaction between somatic growth, feeding and metabolism
(Elsevier Ireland, 2020-12)
This review covers the current knowledge on the regulation of the somatic growth axis and its interaction with metabolism and feeding regulation. The main endocrine and neuroendocrine factors regulating both the growth ...
Electrodeposition of CdTe thin films onto n-Si(1 0 0): Nucleation and growth mechanisms
(2005)
The mechanisms related to the initial stages of the nucleation and growth of cadmium telluride (CdTe) thin films on the rough face side of a (1 0 0) monocrystalline n-type silicon have been studied as a function of different ...
Nucleation and growth mechanism of polycarbazole deposited by electrochemistry
(SOC BRASILEIRA QUIMICA, 2007)
Polycarbazole (PCz) thin films have been deposited by electro-oxidation of carbazole in LiCIO, + anhydrous acetonitrile onto SnO2 coated glass substrates, by potentiostatic method and the nucleation and growth mechanism ...
