An Outline Of The Biology of the Squid Illex Coindetii in the Sicilian Channel (Central Mediterranean)
No full textThe genus Illex is likely to constitute a large portion of the annual world ommastrephid squid catches (Roper et al, 1984), even though specific official statistics are difficult to obtain. The broad-tail short-fin squid Illex coindetii is a widespread species ranging from the western to the eastern Atlantic (Roper et al., 1984) and east through the whole Mediterranean Sea (Mangold & Boletzky, 1987). Usually a by-catch of important fisheries, it is caught mainly by trawlers. Although its economic value is lower than that of other squid species (i.e. Loligo spp.), in the Sicilian Channel Illex coindetii may represent a valuable resource due to its abundance. In Italian waters, the available statistics (Cingolani et al., 1986) report that 2680 tonnes of ommastrephid squid were landed in 1982 (0.5% of the total landed catch). The main component of these was landed in Sicily (2183 tonnes), a consistently large part of which was no doubt Illex coindetii (Ragonese & Jereb, 1992). The catches came mainly from southern Sicilian waters (Sicilian Channel) where one of the major Mediterranean landing places is in Mazara del Vallo. Large trawlers (up to 200 gross tonnage) usually carry out long fishing trips (15–20 d), and Illex coindetii is caught mainly by those targeting Parapenaeus longirostris and Merluccius merluccius (Jereb & Ragonese, 1991)

No full textMortality in multiple sclerosis: a review.
No full textThis work was undertaken to evaluate studies on mortality caused by multiple sclerosis (MS), to evaluate if useful inferences can be drawn from survival studies that can be applied to clinical practice. A literature search was carried out to find epidemiological studies on MS prognosis, survival, mortality and causes of death relevant to our aim. The World Health Organization (WHO) reports on worldwide cause-specific mortality were also considered. Studies were evaluated according to the duration of the follow-up study, the year of publication and the methodology used. We evaluated MS survival from a methodological point of view and considered if time trends could be drawn from study results. We conclude that mortality is only slightly higher in MS patients when compared with that in the general population. Mortality is higher particularly for older patients and those with longer disease duration
Coronary microvascular endothelial dysfunction in transplanted children
No full textAims To assess the response of the coronary microcirculation to acetylcholine (endothelium-dependent vasodilator) and of adenosine (endothelium-independent vasodilator) in children after heart transplantation and to verify whether endothelial dysfunction is time-dependent. Methods and Results Ne studied the endothelial function of 26 asymptomatic children previously submitted to heart transplantation, with normal transplanted hearts and epicardial coronary arteries. Ten untransplanted children served as controls. The response of coronary blood dow velocity to intracoronary infusion of acetylcholine (1.8 mug.min(-1)) and adenosine (270 mug.min(-1)) was assessed using a Doppler wire positioned in an epicardial coronary branch. In the study group, coronary blood flow velocity increased slightly during acetylcholine infusion (geak/baseline ratio=1.17 +/- 0.22). The ratio was inversely correlated with the length of follow-up (r=-0.50; P=0.0078). The peak/baseline ratio in control children was 1.76 +/- 0.73 (P<0.0002 vs study group). After adenosine infusion, the coronary blood flow velocity peak/baseline ratio was 3.75 +/- 1.54 in transplanted children and 3.72 +/- 1.34 in controls (P=ns). Conclusions Endothelial dysfunction in paediatric transplanted patients becomes more evident in patients with longer follow-up. This finding could grove useful in the prevention of accelerated arteriosclerosi
