Lack of interaction between α2-adrenoceptors and dopamine D2-receptors in mediating their inhibitory effects on [3H]dopamine release from rat nucleus accumbens slices
The α2-adrenoceptor agonist, UK14304, dose-dependently inhibited the electrically stimulated release of dopamine (DA) from rat nucleus accumbens slices. This effect was antagonized by idazoxan, confirming that it was an ...
Localized basal meningeal enhancement in tuberculous meningitis
Background: Focal basal meningeal enhancement may produce a confusing CT picture in children with suspected tuberculous meningitis (TBM). Objective: To demonstrate the incidence, distribution and appearance of localized ...
Effects of α2- and β-adrenoceptor agonists on growth hormone secretion following lesion of the noradrenergic system of the rat
The aim of the present investigation was to lesion the noradrenergic system and to measure the effect on growth hormone (GH) secretion following peripheral administration of α2- and β-adrenoceptor agonists. Direct injection ...
Value of different staging systems for predicting neurological outcome in childhood tuberculous meningitis
BACKGROUND: The stage of tuberculous meningitis (TBM) at presentation is strongly associated with prognosis. OBJECTIVE: To compare different staging systems for TBM in predicting outcome. METHODS: The associations of ...
In vitro fertilization failure: Identification of gamete defects by investigation of sperm-zona pellucida binding capacity of unfertilized oocytes
The objective of the study was to determine whether fertilization failure was due to spermatozoal or oocyte factors. Twenty-five unfertilized oocytes and from 12 IVF/GIFT couples showing total or partial fertilization ...
TUNEL assay and SCSA determine different aspects of sperm DNA damage
Summary For the determination of sperm DNA damage, different assays are used. However, no further distinction is made and the literature generally speaks about DNA damage. Thus, this study aimed at comparing the sperm ...
Leucocytes and intrinsic ROS production may be factors compromising sperm chromatin condensation status
Considering that the final protection of the DNA against major assaults in terms of chromatin condensation is finalised in the epididymis, it is not known how sperm production of reactive oxygen species (ROS) and inflammatory ...

Longer duration of breastfeeding associated with reduced risk of developing schizophrenia
Background. Some studies have suggested that breastfeeding may be protective against the development of schizophrenia. Such a theory supports the neurodevelopmental hypothesis of schizophrenia. Objective: To determine ...
Zona pellucida as physiological trigger for the induction of acrosome reaction
To evaluate the kinetics of acrosome reaction, sperm samples from four fertile donors were prepared by swim-up and incubated with solutions of human zonae containing 0.1, 0.15, 0.3, 0.5 and 1.0 zonae μl-1. After 20, 40 and ...
