FLiGS Score: A New Method of Outcome Assessment for Lip Carcinoma–Treated Patients

2015

Lip cancer represents 25% of all oral cavity carcinomas; it peaks in the sixth and seventh decades, with males predominating by 3 to 1. The lower lip is approximately 12 times more likely to be affected, owing to its greater exposure to the sunlight. Surgical oncologic and reconstructive treatment of lip cancer has advanced dramatically, but lip distortion or loss resulting from neoplasms or from their surgical treatment has considerable functional and cosmetic effects with resultant nutritional, physical, and psychological detriments.1–8 Traditional indicators, such as survival rate and disease-free interval, are no longer adequate for answering questions on outcome not considering the phy…

Porcine Model for Gluteal Artery Perforator Flap: Anatomy and Technique

2018

Although flap anatomy is well studied on cadavers and microsurgical techniques are well practiced on rats, still there are few training models for learning the techniques of perforator flap harvesting. The cadaver has no bloodstream, so accuracy of dissection cannot be evaluated and flap viability cannot be verified. Training on humans carries a high risk of flap damage. A living model for perforator flap harvest is needed to learn the technique before starting with its clinical application.

EFFECT OF IONIC STRENGTH AND MEDIUM COMPOSITION ON THE REMOVAL OF Pb2+ BY ALGINATE GEL BEADS. DPVASV AND ICP-OES MEASUREMENTS.

2012

The biosorption, i.e. a passive sequestering process by metabolically inactive biomass, shows a growing interest for toxic metal ions removal from contaminated aqueous solutions (1), such as municipal and industrial wastewaters. Since the sorption mechanism occurs mainly by ion exchange between the metal ion present in solution and the counter ion of the biopolymer (2), the efficiency of the sorption process largely depends on ionic strength and on the medium composition of solution containing the metal ion to be removed. In order to evaluate quantitatively the influence of ionic strength and medium on the metal removal process by the biomass, we report here results of a study on the sorpti…

Determination of metal concentrations in certified plastic reference materials after small-size autoclave and microwave-assisted digestion followed w…

2017

Abstract The digestion methods for the determination of As, Cd, Cr, Pb, Sb, Sn and Zn concentrations in plastic samples using microwave-assisted digestion (MW-AD) and small-size autoclave digestion was developed. The certified polyethylene, polypropylene, polyvinyl chloride and acrylonitrile butadiene styrene certified reference materials were used in order to find digestion method working properly for several sample matrices. Efficiency of the digestion methods was evaluated by analyzing the residual carbon in digests by TOC analyzer. MW-AD using a mixture of 7 mL of HNO 3 and 3 mL of H 2 O 2 as a digestion solution resulted in excellent recoveries for As, Cd, Pb, Sb and Zn, and were in th…

Bedrock and soil geochemistry influence the content of chemical elements in wild edible mushrooms (Morchella group) from South Italy (Sicily)

2019

Chemical elements in the samples of wild edible mushrooms of the <em>Morchella</em> group collected from different unpolluted Sicilian sites was analyzed by the ICP-MS (method) to detect the content of their minerals and determine whether soil geology and geochemistry can influence the chemical composition in fungi. Results showed that the mushroom samples mainly contained a high concentration of K and P and a wide variety of minor and trace elements (V, Mo, Pb, Ce, Cs, Zr), including heavy metals. Statistical analysis showed that the mushrooms differed in their content of minor and trace elements based on the geological/geographic site of origin. Comparison with other studies s…

Indirect chronology method employing rare earth elements to identify Sagunto Castle mortar construction periods

2017

A novel indirect chronology method has been developed to identify Sagunto Castle construction periods. The method is based on the use of inductively coupled plasma mass spectrometry (ICP-MS) to determine rare earth elements (REE) and other trace elements in mortars. Additionally, a no destructive geochemical analysis based on X-ray fluorescence (XRF) was employed for major elements determination. Collected chemical data were processed through Principal Component Analysis (PCA) to highlight any differences among the mortars belonging to different buildings and construction periods. The results show that PCA analysis permits to discriminate construction periods according to mortar sample REE …

Oluen hivenainepitoisuuksien analysointi

2015

Tämän Pro gradu -tutkielman kirjallisessa osassa käsiteltiin hivenaineiden tarvetta palautumisen kannalta ja alkoholin tuottamia vaikutuksia palautumiseen. Lisäksi selvitettiin orgaanista ainesta sisältävien näytteiden esikäsittelymenetelmiä ja induktiivisesti kytketyn plasma-optisen emissiospektrometrin (ICP-OES) käyttöä hivenaineiden analysoinnissa. Ultraääni, mikroaalto, tuhkistus ja muita esikäsittelymenetelmiä ja niiden eroavaisuuksia ja eroja esiteltiin, koska oluen hivenaineanalyysien onnistumiseksi on erityisen tärkeää saada hiilidioksidi poistumaan näytetaustasta ja nämä menetelmät olivat hyväksi havaittuja kyseiseen toimintaan. Oluesta löytyy kirjallisuudesta hyvin vähän tutkimuks…
