Tumbling Mill Process as a Tool to Develop Core-Shell Nanoparticles for Biomedical Applications. Preliminary Analysis and Testing.

A new mechanical dry process able to develop nanoparticles coated with polymeric material is proposed. An opportunely developed pilot ball milling apparatus permitted to catch-up significant process parameters that are here reported. A proper analysis of the obtained parameters permitted to individuate optimized milling conditions and to prepare a magnetite/albumin core/shell nanocomposite, material with a potential wide spread of applications in biomedical fields.

Five-year results of sleeve gastrectomy.

Objective: Our purpose was to evaluate the efficacy and safety of sleeve gastrectomy (SG) at 5 years after surgery.

Patients And Methods: From June 2005 to January 2007, 65 obese patients underwent SG. The percentage of excess weight loss (%EWL) and excess BMI loss (% EBL), obesity-related co-morbidities, and post-SG complications were evaluated at 2 years after SG based on our database, and at 5 years after SG based on a questionnaire sent to the patients by one of the authors (IB) between May 2011 and February 2012.

Percutaneous radiological gastrostomy in esophageal cancer patients: a feasible and safe access for nutritional support during multimodal therapy.

Background: Percutaneous endoscopic gastrostomy is not widely used in malnourished esophageal cancer (EC) patients because of concerns about its feasibility in frequently obstructive tumors, suitability of the stomach as an esophageal substitute, and potential for metastatic inoculation. A percutaneous radiological gastrostomy (PRG) could be an optimal alternative.

Methods: Experience with PRG among 1,205 consecutive patients presenting with EC from 2002 to 2011 in our department was retrospectively reviewed.

Weight loss after sleeve gastrectomy in super superobesity.

Objective. This prospective study evaluated laparoscopic sleeve gastrectomy for its safety and efficiency in excess weight loss (%EWL) in super superobese patients (BMI >60 Kg/m(2)). Results.

A monitoring tool of workers' activity at Video Display Terminals for investigating VDT-related risk of musculoskeletal disorders.

Today the risk factors related to the use of Video Display Terminals (VDT) are assessed by investigating the actual activities at the VDT through subjective questionnaires and/or quantitative measurements. Questionnaire outcomes are quite imprecise and seldom objective. Quantitative measurements (EMG recordings, electrogoniometers, motion analysis systems) mostly prevent subjects from moving freely while working at the VDT.
