    The Italian Almond Industry: New Perspectives and Ancient Tradition

    The almond industry in Italy presents a high degree of structural variability that is determined by the jeopardized coexistence of old, traditional orchards and new plantations that differ each other not only in terms of age but also mainly in terms of orchard system. Apulia and Sicily still remain the most important production areas where the 90% of the almond orchards are concentrated. In this southern part of Italy, almond and its derivatives still remain really important. In the last two decades, the Italian almond industry did not show a regular trend, neither with respect to production nor to acreage. An innovative almond industry revealed its consistency year after year since 2000: self-fertile cultivars, clonal rootstocks and new planting design ideal for mechanization were the most important technical aspects which revealed a new way to set up almond orchards. As a matter of fact, the Italian almond industry is still characterized by two strongly different structures: a traditional one, which is based upon old cultivars and orchard systems, with unsatisfactory yields indeed, and an innovative one which is really interesting and appears to be able to partially renew the sector. Technical aspects on this new way to obtain innovative almond orchards and their perspectives are here reported mostly in terms of technical choices

    Evaluation of the Efficacy and Safety of an Exercise Program for Persons with Total Hip or Total Knee Replacement:Study Protocol for a Randomized Controlled Trial

    Total hip replacement (THR) and total knee replacement (TKR) are among the most common elective surgical procedures. There is a large consensus on the importance of physical activity promotion for an active lifestyle in persons who underwent THR or TKR to prevent or mitigate disability and improve the quality of life (QoL) in the long term. However, there is no best practice in exercise and physical activity specifically designed for these persons. The present protocol aims to evaluate the efficacy and safety of an exercise program (6 month duration) designed for improving quality of life in people who had undergone THR or TKR. This paper describes a randomized controlled trial protocol that involves persons with THR or TKR. The participant will be randomly assigned to an intervention group or a control group. The intervention group will perform post-rehabilitation supervised training; the control group will be requested to follow the usual care. The primary outcome is QoL, measured with the Short-Form Health Survey (SF-36); Secondary outcomes are clinical, functional and lifestyle measures that may influence QoL. The results of this study could provide evidence for clinicians, exercise trainers, and policymakers toward a strategy that ensures safe and effective exercise physical activity after surgery

    Objective: Cardiac tamponade is a life-threatening clinical entity that requires an emergency treatment. Cardiac tamponade can be caused both by benign and malignant diseases. A variety of methods have been described for the treatment of these cases from needle-guided pericardiocentesis, balloon-based techniques to surgical pericardiotomy. The Authors report their experience in surgical management of cardiac tamponade and an exhaustive review of literature. Methods: This study involved 61 patients (37 males and 24 females) with an average age of 61.80 ± 16.32 years. All patients underwent emergency surgery due to the presence of cardiac tamponade. Results: Cardiac tamponade was caused by a benign disease in 57.40% of patients. In cancer patients group, lung cancer, breast cancer and malignant pleural mesothelioma were the most common neoplasms (17-27, 87%). The average preoperative size of pericardial effusion at M-2D echocardiography was 30.15 ± 5.87 mm. Postoperative complications were observed in 11 patients (18%). The reoperation rate was 3.3% (2 patients) due to relapsed cardiac tamponade. 30-day mortality rate was 3.3%. Overall cumulative survival was 29.9 ± 20.1 months. Twenty-nine patients (47.5%) died during the follow up period. By dividing the population into two groups, group B (benign) and group M (malignant), there was a statistically significant difference (P<0.001) in terms of survival. Conclusion: In conclusions, anterior minithoracotomy for surgical treatment of cardiac tamponade has to be held into account in patients both with benign diseases and malignancies. Keywords: Cardiac tamponade, Minithoracotomy, Pericardial malignancies, Overall surviva

    The interaction of native DNA with iron(III)-N,N’-ethylene-bis(salicylideneiminato)-chloride

    The interaction between native calf thymus deoxyribonucleic acid (DNA) and FeIII-N,N′-ethylene-bis (salicylideneiminato)- chloride, Fe(Salen)Cl, was investigated in aqueous solutions by UV-visible (UV-vis) absorption, circular dichroism (CD), thermal denaturation and viscosity measurements. The results obtained from CD, UV-vis and viscosity measurements exclude DNA intercalation and can be interpreted in terms of an electrostatic binding between the Fe(Salen)+ cation and the phosphate groups of DNA. The trend of the UV-vis absorption band of the Fe(Salen)Cl complex at different ratios [DNAphosphate]/[Fe(Salen)Cl] and the large increase of the melting temperature of DNA in the presence of Fe(Salen)Cl, support the hypothesis of an external electrostatic interaction between the negatively charged DNA double helix and the axially stacked positively charged Fe(Salen)+ moieties, analogously to what reported for a number of porphyrazines and metal-porphyrazine complexes interacting with DNA
