Journalism Education in the GCC Region: University Students' and Professionalism Perspectives

This study investigates the perceptions of Gulf Cooperation Council (GCC) students and professional journalists regarding the quality of curriculum and training sessions that they received at the University and afterwards by looking at curriculum, training sessions and practical programmes related to journalism education, as well as the quality of academic staff and trainings for both GCC journalism students and professionals. A survey was administered to a random sample of 369 students at GCC universities and 34 journalists. Based on the analysed data, the study found that journalism education in the GCC regions is interesting and enjoyable, with respondents being found as ambition, talent skills and motivated. More practical rather than theoretical approach is needed to proof the quality of journalism in the region, though a good number of GCC journalists have had a formal academic journalism qualification. GCC journalism education attempts to reflect the developmental trends in the region

Correlation between mRNA levels and functional role of 1-adrenoceptor subtypes in arteries: evidence of 1L as a functional isoform of the 1A-adrenoceptor

10 pages, 3 figures, 10 tables.-- PMID: 15951348 [PubMed]The mRNA levels for the three alpha1-adrenoceptor subtypes, alpha1A, alpha1B, and alpha1D, were quantified by real-time RT-PCR in arteries from Wistar rats. The alpha1D-adrenoceptor was prominent in both aorta (79.0%) and mesenteric artery (68.7%), alpha1A predominated in tail (61.7%) and small mesenteric artery (73.3%), and both alpha1A- and alpha1D-subtypes were expressed at similar levels in iliac artery. The mRNA levels of the alpha1B-subtype were a minority in all vessels (1.7-11.1%). Concentration-response curves of contraction in response to phenylephrine or relaxation in response to alpha1-adrenoceptor antagonists on maximal sustained contraction induced by phenylephrine were constructed from control vessels and vessels pretreated with 100 micromol/l chloroethylclonidine (CEC) for 30 min. The significant decrease in the phenylephrine potency observed after CEC treatment together with the inhibitory potency displayed by 8-{2-[4-(2-methoxyphenyl)-1-piperazinyl]-8-azaspiro (4,5) decane-7-dionedihydrochloride} (BMY-7378, an alpha1D-adrenoceptor antagonist) confirm the relevant role of alpha1D-adrenoceptors in aorta and iliac and proximal mesenteric arteries. The potency of 5-methylurapidil (an alpha1A-adrenoceptor antagonist) and the changes in the potency of both BMY-7378 and 5-methylurapidil after CEC treatment provided evidence of a mixed population of alpha1A- and alpha1D-adrenoceptors in iliac and distal mesenteric arteries. The low potency of prazosin (pIC50 < 9) as well as the high 5-methylurapidil potency in tail and small mesenteric arteries suggest the main role of alpha1A/alpha1L-adrenoceptors with minor participation of the alpha1D-subtype. The mRNA levels and CEC treatment corroborated this pattern and confirmed that the alpha1L-adrenoceptor could be a functional isoform of the alpha1A-subtype.This work was supported by a research grant from the Spanish Comisión Interministerial de Ciencia y Tecnología (SAF2001-2656).

Pathological role of a constitutively active population of α(1D)-adrenoceptors in arteries of spontaneously hypertensive rats

1. The role of a constitutively active population of α(1D)-adrenoceptors was analysed in arteries obtained from spontaneously hypertensive rats (SHR) and controls (WKY) divided into three groups: young prehypertensive, adult hypertensive, and adult animals chronically treated with captopril (50 mg kg(−1) per day orally) in order to prevent the hypertensive state. 2. In adult SHR, a significant increase in BMY 7378 potency (not in prazosin potency) was observed in aorta, mesenteric artery, and the first and second branches of the small mesenteric arteries with respect to WKY rats. This difference was not observed in iliac and tail arteries, which suggests an increased functional role of α(1D)-adrenoceptors only in some vessels of SHR. 3. The increase in the resting tone (IRT) observed in absence of agonist, inhibited by BMY 7378, that represents the constitutively active population of α(1D)-adrenoceptors, was also significantly greater in aorta and mesenteric artery from adult SHR. 4. In young and captopril treated adult animals, no differences between strains with respect to BMY 7378 potency, or IRT were observed. 5. The increase in the functional role of α(1D)-adrenoceptors and their constitutive activity observed in hypertension is prevented by captopril treatment. The pathological consequence of this change is the slower rate of recovery of the basal tone after removal of an adrenergic stimulus, observed in vessels from hypertensive animals that had shown an increase in the functionality of constitutively active α(1D)-adrenoceptors. This change was not observed in prehypertensive or captopril treated animals
