A group G is called a PC-group if the factor group G/CG（〈X）^G） is polycyclic for each element x of G. It is proved here that if G is a group of infinite rank whose proper subgroups of infinite rank have the property PC, then G itself is a PC-group, provided that G has an abelian non-trivial homomorphic image. Moreover, under the same assumption, a complete classification of minimal non-PC groups is obtained.

A group is called a Cernikov group if it is abelian-by-finite and satisfies the minimal condition on subgroups. A new characterization of Cernikov groups is given here, by proving that in a suitable large class of generalised soluble groups they coincide with the groups having only finitely many homomorphic images of finite rank （up to isomorphisms） and admitting an ascending normal series whose factors have finite rank.

The essay provides an up-to-date review of the realities of Italian restoration. Restoration work feeds off the doubt that stems directly from historical and balance, and a conceptual rigour and practical approach at the same time. Restoration is carried out always and only on the original, with all the attendant risks of error and damage, and thus with all the prudence that demands. One of the most recent definitions of restoration is put forward：＂By restoration, therefore, is meant any intervention that has the aim of conserving and transmitting to the future works of historical, artistic and environmental interest, facilitating the reading of them while not erasing the traces of the passage of time this is based on a respect for ancient material land the authentic documentation that such works constitute and, moreover, is to be seen as a critical act of interpretation that is not verbal but expressed concretely in the work carried out. Or, more precisely, it is a critical hypothesis and a proposition that is always modifiable, without it ever altering irreversibly the original＂. The true nature of restoration is a complete fusion of historical and technical-scientific expertise. It is therefore artificial to distinguish between a ＇project of consolidation＇ and a truly described restoration project. This is a distinction based on the assumption （to be demonstrated） that in an ancient building static problems and those related to the materials can be isolated and treated separately from an overall understanding of the architectural ensemble. So the paper stresses research methodology, the project and specific skills. As part of the principle of unity of methods in restoration, interdisciplinarity is viewed as the principal toot for bringing together consistently and fully the different skills necessary for the study and conservation of monuments. In summary, there are three fundamental components：（1） the history of architecture and theory of restoration; （2） the

Non-alcoholic fatty liver disease(NAFLD)has become one of the most important causes of chronic liver disease in Western countries(1).The increasing prevalence of this liver disease parallels the global epidemics of both obesity and type 2 diabetes(T2DM)in many parts of the world(1).NASH is also projected to become the most common indication for liver transplantation in the near future(1).

Following a few preliminary remarks on the tunneling methods at the beginning of the 20th century, thesuccessful applications of the full-face method also in difficult conditions are underlined. The attention isposed on the use of a systematic reinforcement of the face and of the ground, by means of fiber-glasselements. A selection of tunnels where this method was used successfully is reported with the purposeof illustrating the wide spectrum of ground conditions where it has been applied. Then, following adescription of the main concepts behind the method, the attention moves from the so-called “heavymethod”, where deformations are restrained, to the “light method”, where deformations are allowedwith the intention to decrease the stresses acting on the primary and final linings. The progress in theapplication of the “light method” is underlined, up to the development of a novel technique, which relieson the use of a yielding support composed of top head steel sets with sliding joints and specialdeformable elements inserted in the primary lining. The well-known case study of the Saint Martin LaPorte access adit, along the Lyon-Turin Base Tunnel, is described. In this tunnel, a yield-control supportsystem combined with full-face excavation has been adopted successfully in order to cope with the largedeformations experienced during face advance through the Carboniferous formation. The monitoringresults obtained during excavation are illustrated, together with the modeling studies performed whenpaying attention to the rock mass time-dependent behavior.

To characterize the genes associated with differentiation/apoptosis induced by all-trans retinoic acid (ATRA) in human lung cancer cells, mRNA differential display was employed. Six cDNA fragments have been isolated, and one of them corresponds to a sequence-known gene DPH2L with unknown function, which was first isolated from the critical region of deletion on chromosome 17p13.3 in human ovarian carcinoma, and regarded as a candidate tumor suppressor gene. Results show that DPH2L is a wide expressed gene, and has another major transcript besides the previously reported 2.3 kb transcript. It is proved that the DPH2L gene is dawn-regulated during differentiation or apoptosis in several kinds of cancer cells induced by all-trans retinoic acid and N-(4-hydroxyphenyl) retinamide (4HPR). This may suggest that DPH2L does not play a role as a tumor suppressor gene, on the contrary, its down-regulation may be functionally involved in the transition from cell growth to differentiation or apoptosis.
