We estimated water-use efficiency and potential photosyn- thetic assimilation of Holm oak （Quercus ilex L.） on slopes of NW and SW aspects in a replicated field test examining the effects of intensifying drought in two Mediterranean coppice forests. We used standard tech- niques for quantifying gas exchange and carbon isotopes in leaves and analyzed total chlorophyll, carotenoids and nitrogen in leaves collected from Mediterranean forests managed under the coppice system. We pos- tulated that responses to drought of coppiced trees would lead to differ- ential responses in physiological traits and that these traits could be used by foresters to adapt to predicted warming and drying in the Mediterra- nean area. We observed physiological responses of the eoppiced trees that suggested acclimation in photosynthetic potential and water-use effi- ciency：（1） a significant reduction in stomatal conductance （p〈0.01） wasrecorded as the drought increased at the SW site; （2） foliar 813C increased as drought increased at the SW site （p〈0.01）; （3） variations in levels of carotenoids and foliar nitrogen, and differences in foliar morphology were recorded, and were tentatively attributed to variation in photosyn- thetic assimilation between sites. These findings increase knowledge of the capacity for acclimation of managed forests in the Mediterranean region of Europe.

We are glad to contribute with an editorial on the important topic of therapeutic opportunities for hepatocellular carcinoma(HCC).The increasing diffusion of minimally invasive approaches to the liver and the growing experience worldwide have progressively changed our curative strategies for patients affected by primary and metastatic liver tumors(1).

Liver transplant(LT)is considered the best option for patients with hepatocellular carcinoma(HCC)confined into the liver and generally associated with liver cirrhosis(1).The Milan criteria(MC)represent a milestone in the selection of these patients(2).Therefore,basing on MC,the 5-year survival rate after LT could increase to 70%,with a HCC recurrence rate lower than 10%(2).Despite that,too many patients affected by HCC may not benefit from LT due to a tumor stage beyond the selection *** the last two decades,authors and physicians tried to overcome the MC exploring the opportunity to safely transplant patients beyond(3).Notably,the donor shortage and the competition between patients listed due to HCC and those listed for other indications,force physicians in selecting candidates with the best transplant benefit(3).

We discussed recent studies, within the framework of transport theories, on heavy ion reactions between charge asymmetric systems, from low up to Fermi energies. We concentrated on the analysis of ternary breakup events of dynamical origin occurring in semi-central reactions, where the formation of excited systems in various conditions of shape, excitation energy and spin is observed. At beam energies around 20 A Me V, we showed how this fragmentation mode emerges from the combined action of surface(neck) instabilities and angular momentum effects, leading to the observation of three aligned massive fragments in the exit channel. At Fermi energies, a transition towards a prompt emission of small fragments from the neck region with larger relative velocity with respect to projectile and target remnants is observed. We also focus on isospin sensitive observables, aiming at extracting information on the density dependence of the isovector part of the nuclear effective interaction and of the nuclear symmetry energy.

Results of analytical surveys on pesticide residue levels in foods for the years 1986-1987 are presented. Analytical data obtained from regional laboratories are tabulated in terms of various commodity groups (vegetables, fruit, cereals, processed or derived foodstuffs, other commodities, legumes, environmental samples, others) and are compared with maximum legal tolerances established by the ministerial ordinance (Italian Ministry of Health) 6.6. 1985.On a total number of 4715 determinations of classes of compounds or of single compounds made on 1601 commodities samples, only N 53 (1.1 %) violative results appeared. No residue was found at levels exceeding regulatory limits or found in commodities where a tolerance had not been established for a specific pesticide/commodity combination.
