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 ...
Selective lysis of erythrocytes infected with the trophozoite stage of Plasmodium falciparum by polyene macrolide antibiotics
The continuous increase in strains of the human malaria parasite Plasmodium falciparum resistant to most front-line antimalarial compounds is reason for grave clinical concern. The search for new drugs led us to investigate ...
Membranes of class IIa bacteriocin-resistant Listeria monocytogenes cells contain increased levels of desaturated and short-acyl-chain phosphatidylglycerols
A major concern in the use of class IIa bacteriocins as food preservatives is the well-documented resistance development in target Listeria strains. We studied the relationship between leucocin A, a class IIa bacteriocin, ...

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 ...
Evaluating the BED capture enzyme immunoassay to estimate HIV incidence among adults in three countries in sub-Saharan Africa
Serological assays for estimating HIV-1 incidence are prone to misclassification, limiting the accuracy of the incidence estimate. Adjustment factors have been developed and recommended for estimating assay-based HIV-1 ...
Microscopic studies on the Aspergillus flavus infected kernels of commercial peanuts in Georgia
This article describes the use of microscopy to prove the presence of the aflatoxin producing pathogen, Aspergillus flavus Link ex Fries in commercially available edible peanuts in Georgia. Light microscopy in combination ...
Proton relative biological effectiveness (RBE) for survival in mice after thoracic irradiation with fractionated doses
Purpose: This study aims at providing relative biological effectiveness (RBE) data under reference conditions accounting for the determination of the 'clinical RBE' of protons.Methods and Materials: RBE (ref. 60Co γ-rays) ...
Radiosensitization and DNA repair inhibition by pentoxifylline in NIH3T3 p53 transfectants
Purpose: To examine the role of p53 mutations in the modulation of DNA repair and radiotoxicity by pentoxifylline. Materials and methods: NIH3T3 murine cells transfected with mutant p53 constructs were examined for the ...
