A Review of the Water Desalination Technologies

2021

Desalination is commonly adopted nowadays to overcome the freshwater scarcity in some areas of the world if brackish water or salt water is available. Different kinds of technologies have been proposed in the last century. In this paper, the state of the mainstream solutions is reported, showing the current commercial technologies like reverse osmosis (RO), Multi-Stages Flash desalination (MSF) and Multi-Effect Distillation (MED), and the new frontiers of the research with the aim of exploiting renewable sources such as wind, solar and biomass energy. In these cases, seawater treatment plants are the same as traditional ones, with the only difference being that they use a renewable energy s…

The Current State of Knowledge on the Clinical and Methodological Aspects of Extracorporeal Shock Waves Therapy in the Management of Post-Stroke Spas…

2021

In many patients after stroke, spasticity develops over time, resulting in a decrease in the patient’s independence, pain, worsening mood, and, consequently, lower quality of life. In the last ten years, a rich arsenal of physical agents to reduce muscle tone such as extracorporeal shock therapy (ESWT) wave has come through. The aim of this narrative review article is to present the current state of knowledge on the use of ESWT as a supplement to the comprehensive rehabilitation of people after stroke suffering from spasticity. The PubMed and PEDro databases were searched for papers published in English from January 2000 to December 2020, 22 of which met inclusion criteria for clinical stud…

The state of art of biological processes in paternal care

2014

This review of the state of art aimed to present the most recent data on neuronal, neurochemical, hormonal and genetic bases of paternal care using MEDLINE and PsycInfo databases (1970-2013). An integrated model of biological substrates that assist men in the transition to fatherhood is presented. Guided by a genetic background, hypothalamic-midbrain-limbic-paralimbic-cortical circuits were found to be activated in fathers when infant stimuli are presented. A set of specifi c neuropeptides and steroid hormones are produced and seem to be related to brain activation, potentiating the paternal phenotype. Together, genetic, brain and hormonal processes suggest the existence of biological bases…

Breast dynamic contrast-enhanced-magnetic resonance imaging and radiomics: State of art

2020

Breast cancer represents the most common malignancy in women, being one of the most frequent cause of cancer-related mortality. Ultrasound, mammography, and magnetic resonance imaging (MRI) play a pivotal role in the diagnosis of breast lesions, with different levels of accuracy. Particularly, dynamic contrast-enhanced MRI has shown high diagnostic value in detecting multifocal, multicentric, or contralateral breast cancers. Radiomics is emerging as a promising tool for quantitative tumor evaluation, allowing the extraction of additional quantitative data from radiological imaging acquired with different modalities. Radiomics analysis may provide novel information through the quantification…

Induction Heating Technology and Its Applications: Past Developments, Current Technology, and Future Challenges

2013

International audience; Induction heating technology is nowadays the heating technology of choice in many industrial, domestic, and medical applications due to its advantages regarding efficiency, fast heating, safety, cleanness, and accurate control. Advances in key technologies, i.e. power electronics, control techniques, and magnetic component design, have allowed the development of highly reliable and cost-effective systems, making this technology readily available and ubiquitous. This papers reviews induction heating technology summarizing the main milestones in its development, and analyzing the current state-of-art of induction heating systems in industrial, domestic and medical appl…

Bacterial metal nanoparticles to develop new weapons against bacterial biofilms and infections

2021

The widespread use of antibiotics has resulted in the outbreak and spread of antibiotic-resistant pathogens. Bacterial antibiotic resistance may develop at cellular and community levels. In the latter case, it is based on tolerance which implicates the shift from a free-living form of life (i.e., planktonic) to a sessile multi-stratified community (i.e., biofilm). Metal nanoparticles (MNPs) have been shown to be promising candidates as antimicrobial agents. MNPs are able to interact with and penetrate bacterial biofilms, thus, resulting effective antibiofilm compounds. Another interesting aspect is the possibility of using plants, fungi, yeasts, and bacteria to obtain biogenic MNPs (BMNP). …

Si traccia brevemente lo stato degli studi sulla musica a Palermo tra Cinque e Seicento, a partire dagli articoli contenuti nel fascicolo, individuando nuove tendenze di ricerca e lacune. This essay aims at reconsidering scholarly studies about musical life in Palermo in 16-17th centuries; new paths of investigation are also discussed.

Direct Oral Anticoagulants in the Setting of Catheter Ablation of Atrial Fibrillation: State of art

2021

Atrial fibrillation (AF) represents the arrhythmia of greatest clinical impact and catheter ablation of AF (CAAF) has become the most effective strategy for rhythm control in selected patients. Therefore, appropriate anticoagulation strategies are of paramount importance for patients undergoing CAAF, especially those at high risk, such those with high CHA2DS2VASc scores. Optimal management of anticoagulation before, during, and after CAAF is crucial. Several studies have evaluated the use of different anticoagulation strategies in the periprocedural period. Randomized controlled trial seem to suggest that in patients undergoing CAAF, uninterrupted (or minimally interrupted) direct oral anti…
