The developmental pattern and the adult distribution of neuropeptide tyrosine (NPY) and its C-terminal flanking peptide (C-PON) were investigated in the spinal cord of the lizard Gallotia galloti. Embryonic, postnatal and adult animals were studied by means of the immunohistochemical technique. Neurons containing both peptide immunoreactivities first(More)
Immunohistochemical methods have been used to study the embryonic and postnatal development of the hormone-producing cells in the adenohypophysis of the lizard Gallotia galloti. In this species, Rathke's pouch is formed between stages 30 to 32 of the embryonic development, although the first sign of immunoreactivity to antisera against adenohypophysial(More)
OBJECTIVE Venlafaxine is a bicyclic antidepressant that may be associated with severe cardiotoxicity following large overdose. The purpose of this short case series is to present different patterns of venlafaxine-related cardiotoxicity and to discuss the potential mechanisms. CASE SERIES Between January 2010 and July 2011, four patients were admitted to(More)
Acid extracts of the pars intermedia of the squamate reptile Lacerta galloti were screened for immunoreactive forms of proopiomelanocortin (POMC)-related end products following Sephadex G-50 column chromatography. alpha-MSH-sized end products were detected with a Val-NH2, C-terminal-specific RIA, and beta-endorphin-sized end products were detected with a(More)
The development of the pituitary Pars Tuberalis (PT) was studied in the lizard Gallotia galloti using classical, histological and immunohistochemical techniques. As early as stage 32 of development, the Rathke's pouch exhibits 2 lateral extensions that will give rise to the PT. In these extensions, cellular proliferation results in the formation of two cell(More)
The corn plants were evaluated with different phosphate fertilizer sources and aluminum (Al) concentrations in a sandy substrate. A totally randomized experiment design was set up with two corn plants in the pots containing 2 kg of a sandy substrate, two phosphate sources (Triple Super Phosphate – TSP or Arad Phosphate – AP) and four Al concentrations. When(More)
The hypophysis of the lizard Gallotia galloti showed substance-P-like immunoreactivity in both the adenohypophysis (pars distalis, PD; pars intermedia, PI) and the neurohypophysis (median eminence and pars nervosa), whereas angiotensin-II-like immunoreactivity appeared only in PD and PI. The elution-restaining procedure has allowed us to demonstrate the(More)
The neural tube in the Gallotia galloti Stage 22 (S.22) embryo is already closed at the level of the cervical flexure, while caudal closure does not end until S.23. Cell proliferation begins shortly after the final neural tube closure, being rapid and giving rise, by S.26, to a thick ventricular zone. Cell migration does not start until S.28, initially in(More)
RESULTS In Cohort 1, CFR was significantly lower (2.12 0.79 vs. 2.56 0.63; p<0.001) and HMR was significantly higher (2.61 1.22 vs. 2.31 0.89; p1⁄40.04) in vessels with CAD than the vessels without CAD, within the same patient. mMR was equivalent in obstructed and nonobstructed vessels: 1.54 0.77 vs. 1.53 0.57; p1⁄40.90. Cohort 2 confirmed these findings,(More)
