No full textRecording of an exceptional aggregation of Milesia crabroniformis in a forest of Northern Italy
Full text linkMilesia crabroniformis (F.) is a large hornet-mimic hoverfly considered relatively rare in Italy. During visual samplings along a transect carried out in Castiglione dei Pepoli (Bologna, Italy), with the aim of monitoring changes in hoverfly communities over sixty years, the authors observed and counted at least one hundred specimens of this hornet-mimic hoverfly while forage on Sam-bucus ebulus L. This note aims to document this very infrequent behaviour of M. crabroniformis to contribute to the understanding of this phenomenon

No full textThe two most widely used sources of hematopoietic stem cells for allogeneic transplants in pediatric practice are bone marrow (BM) and cord blood (CB), While bone marrow transplantation (BMT) is reaching its 30th year of application, human umbilical cord blood transplantation (HUCBT) is approaching its 10th. Although these procedures have basically the same purpose, a number of biological differences distinguish them. In particular, the intrinsically limited quantity of CB stem cells and their immunological naivete confer peculiar characteristics to these hematopoietic progenitors. From a bioethical point of view, the problems which have repeatedly been raised when the BM donor is a child are well-known. Different but no less important ethical problems are raised when one considers HUCBT; in this regard the most important issues are the easier propensity of programming a CB donor in comparison with a BM donor (clearly due to the shorter time interval needed to collect the hematopoietic progenitors); the in utero HLA-typing; the implication of employing 'blood belonging to a neonate' for a third party; the need to perform a number of investigations both on the CB of the donor and on the mother and the implications that the discovery of disease may have for them, but also the need to establish banks for storing CB, with the accompanying administration and management problems. All these different aspects of UCBT will be discussed in the light of the four fundamental and traditional principles of bioethics, namely autonomy, nonmaleficence, beneficence and justice
Alternative therapies and the Di Bella affair in pediatrics. A questionnaire submitted to Italian pediatric oncologists and hematologists
No full textOver the last 2-3 years in particular, the so-called Di Bella therapy (DBT) become the most famous of alternative treatments applied to pediatric oncology and hematology in Italy. Many Italian oncologists and hematologists had to cope with the problems that it introduced and the treatment also elicited heated reactions all over Europe. We attempted to evaluate the impact of this treatment on children with cancer. A questionnaire prepared with the aim of addressing the use of alternative therapies in pediatric hematology and oncology was circulated to the 48 centers (or divisions) belonging to AIEOP (Associazione Italiana di Oncoematologia Pediatrica) [Italian Pediatric Oncology and Hematology Association] and FONOP (Forza Operativa Nazionale di Oncologia Pediatrica) [National Pediatric Oncology Task Force]. The questionnaire consisted of 9 questions elaborated to give credit to the case-related and professional experiences of the colleagues we contacted. Forty-three centers replied to the questionnaire. Request to switch to DBT represented a considerable problem, involving the vast majority of centers participating into this study; however, case quantification varied greatly from center to center. One of the most significant aspects is that children switched to DBT, abandoning conventional therapies, were often relapsing or had had multiple relapses (from solid tumor or leukemia), but some children abandoned conventional therapies at an early stage and/or without fully exploiting the curative potential of these therapies. This study allowed us to obtain an evaluation of the impact of DBT in children with oncologic or hematologic disorders. It also highlights the importance of cultivating physician-parent dialogue and provides an opportunity for a few pedagogic thoughts on the attitude and opinions of pediatricians on this problem
The role of ecological compensation areas in conservation biological control
Full text linkEcological compensation areas (ECAs), defined as all natural vegetation and non-crop plants within the rural landscape, are considered an important tool in multifunctional agriculture. In particular, ECAs are crucial in enhancing functional biodiversity for pest suppression and for the conservation of rare species. In my PhD thesis I focused on the role of ECAs on functional biodiversity, which is associated with the ecological services employed by the beneficial fauna. Within multifunctional agriculture, functional biodiversity is particularly aimed at establishing strategies for farmers to enhance ecosystem functioning for pest suppression and for conservation of insect diversit
