Influence of rootstocks on growth, yield, fruit quality and leaf mineral element contents of pear cv. 'Santa Maria' in semi-arid conditions

Biol. Res; 47 (), 2014
BACKGROUND: Rootstocks play an essential role to determining orchard performance of fruit trees. Pyrus communisand Cydonia oblonga are widely used rootstocks for European pear cultivars. The lack of rootstocks adapted to different soil conditions and different grafted cultivars is widely acknowledged in ...

Activation of group II metabotropic glutamate receptors blocks zinc release from hippocampal mossy fibers

Biol. Res; 47 (), 2014
BACKGROUND: The hippocampal CA3 area contains large amounts of vesicular zinc in the mossy fiber terminals which is released during synaptic activity, depending on presynaptic calcium. Another characteristic of these synapses is the presynaptic localization of high concentrations of group II metabotropic...

Efecto del consumo de casabe venezolano sobre la absorción de minerales en un modelo experimental con ratas
Effect of consumption of Venezuelan casabe on mineral absorption in a experimental model with rats

Rev. Inst. Nac. Hig; 44 (2), 2013
El principal producto derivado de la yuca en Venezuela es el casabe, el cual es valorado por su contenido calórico, riqueza en Fibra Dietética (FD) y minerales. En este estudio se determinó el efecto del consumo de diferentes variedades de casabe venezolano sobre la absorción de hierro, cobre y zinc,...

Inorganic elemental analysis and identification of residual monomers released from different glass ionomer cements in cell culture medium

Introduction: Glass ionomer cements (GICs) release inorganic elements and organic residual monomers with the potential for deleterious effects on pulp cells. Objective: To identify and quantify inorganic elements present in different GICs and released components from these materials in cell culture mediu...

Effects of zinc during lactation on the junctional epithelium and inserted gum in rats

Int. j. morphol; 31 (1), 2013
The purpose of this study was to evaluate the effects of zinc, during lactation, on the junctional epithelium and inserted gum of the first upper molar of rats. The study used one-day old male rats, divided into two groups: those whose mother had been treated with 300 mg zinc chloride (ZnCl2) in the drin...

Importance of genetic polymorphisms in the response to age-related macular degeneration treatment

Rev. bras. oftalmol; 71 (3), 2012
Age-related macular degeneration (AMD) is a degenerative disorder that affects the central retina and involves the Bruch's membrane, the retinal pigment epithelium and the photoreceptors. Recent studies have shown that polymorphisms of the CFH, LOC387715 and VEGF genes are associated with AMD. Herein, we...

Different levels of MT-I/II between patients with MTLE with or without seizure generalization: does hippocampal MT-I/II affects seizure spread, or does seizure spread promotes differential expression of MT-I/II?

In the central nervous system, zinc is released along with glutamate during neurotransmission and, in excess, can promote neuronal death. Experimental studies have shown that metallothioneins I/II (MT-I/II), which chelate free zinc, can affect seizures and reduce neuronal death after status epilepticus. ...
