Two different types of graphene flakes were produced following solution processing methods and dispersed using shear mixing in a bifunctional(A) and a multifunctional(B) epoxy resin at a concentration of 0.8 and 0.6 wt%, respectively. The graphene/epoxy resin mixtures were used to impregnate unidirectional carbon fibre tapes. These prepregs were stacked(seven plies) and cured to produce *** interlaminar fracture toughness(mode-I) of the carbon fiber/graphene epoxy laminates with resin B showed over 56% improvement compared with the laminate without graphene. Single lap joints were prepared using the laminates as adherents and polyurethane adhesives(Sika 7666 and Sika 7888). The addition of graphene improved considerably the adhesion strength from 3.3 to 21 MPa(sample prepared with resin A and Sika 7888) highlighting the potential of graphene as a secondary filler in carbon fibre reinforced polymer composites.

Advances in Microgeophysics for Engineering and Cultural Heritage

引用

Journal of China University of Geosciences 2009年第3期20卷 626-639页

作者： P L Cosentino P Capizzi G Fiandaca R martorana P Messina Department of Chemistry and Physics of the Earth and Applications to Geo-Resources and Natural Risks Geophysical Section University of PalermoPalermo Italy

A large number of unconventional investigations have been implemented, tested, and validated in the field of microgeophysics, with the aim being to solve specific diagnostic and/or monitoring problems regarding civil engineering and cultural heritage studies. The investigations were carried out using different tomographic 2D and 3D approaches as well as different energy sources, namely sonic, ultrasonic and electromagnetic （radar） waves, electric potential fields, and infrared thermography. Many efforts have been made to modify instruments and procedures in order to improve the resolution of the surveys as well as to greatly reduce the time of the measurements without any loss of information. The main new methodologies here discussed are the sonic imprint, the global tomographic traveltime, the electrical resistivity tomography, and the control of external films （patinas） grown on stone monuments. The results seem to be very promising and suggest that it is the moment to dedicate time and effort to this new branch of geophysics, so that these methodologies can be used even more to diagnose, monitor, and safeguard not only engineering buildings and large structures but also ancient monuments and cultural artifacts, like pottery, statues, etc..

Gender specific medicine in liver diseases:a point of view

引用

World Journal of Gastroenterology 2014年第9期20卷 2127-2135页

作者： Marilena Durazzo Paola Belci Alessandro Collo Vanessa Prandi Erika Pistone Maria martorana Roberto Gambino Simona Bo Department of Medical Sciences University of Turin 10126 Turin Italy

Gender medicine focuses on the patho-physiological, clinical, prevention and treatment differences in diseases that are equally represented in men and women. The purpose of gender medicine is to ensure that each individual man and woman receives the best treatment possible based on scientific evidence. The concept of “gender” includes not only the sexual characteristics of individuals but also physiological and psychological attributes of men and women, including risk factors, protective/aggravating effects of sexual hormones and variances linked to genetics and corporal structures that explain biological and physiological differences between men and women. It is very important to consider all the biological, physiological, functional, psychological, social and cultural characteristics to provide patients with individualized disease management. Herein, we critically analyze the literature regarding gender differences for diseases and acquired conditions of the most representative hepatic pathologies: primary biliary cirrhosis, autoimmune hepatitis, primary sclerosing cholangitis, non alcoholic fatty liver disease and alcoholic liver disease, and viral chronic hepatitis B and C. The last section addresses hemochromatosis, which is a prevalent iron overload disorder in the Caucasian population. This review aims to describe data from the literature concerning viral chronic hepatitis during pregnancy, management during pregnancy and delivery, and new effective drugs for the prevention of maternal infection transmission without significant adverse effects or complications.

Testosterone decreases adiponectin levels in female to male transsexuals

引用

Asian Journal of Andrology 2006年第6期8卷 725-729页

作者： Marta Berra Francesca Armillotta Laura D'Emidio Antonietta Costantino Giuseppe martorana Giuseppe Pelusi MariaCristina Meriggiola Department of Obstetrics and Gynecology Department of Urology S.Orsola-Malpighi Hospital University of BolognaBologna 40138Italy

Aim： To evaluate the effect of testosterone （T） on adiponectin serum levels in transsexual female patients. Methods： We measured adiponectin, leptin, luteinizing hormone and follicle stimulating hormone, T, estradiol, lipid profile, biochemical parameters and body composition in 16 transsexual female patients at baseline and after 6 months of T treatment （100 mg Testoviron Depot/10 days, i.m.）. Results： Adiponectin levels were 16.9 ± 7.3 mg/mL at baseline and 13.5 ± 7.4 mg/mL at month 6 of T treatment （P 〈 0.05）. Leptin and high-density lipoprotein cholesterol decreased significantly, whereas body mass index, waist circumference and lean body mass increased significantly after 6 months of T treatment. No changes in insulin or Homeostasis Model Assessment were detected. Conclusion： T can significantly reduce adiponectin serum levels in transsexual female patients.

Aim:The liver is a sexually dimorphic organ presenting gender differences in its metabolism,functions,enzyme activity,membrane lipid composition and immune *** paper aimed to assess whether gender may predict virological response to standard antiviral therapy in subjects with chronic hepatitis C(CHC).Methods:The authors retrospectively analyzed 100 patients with genotype 1 CHC(55 men,45 women),who performed standard antiviral therapy(interferon and ribavirin for 12 months)in the period 2002-2012,evaluated with blood tests and abdominal ultrasound to compare different virological and biochemical response in both ***:Rate of substained virological response(SVR)was higher,but not significant,in women than men(46.7%vs.34.5%,P=0.05);difference became significant after stratification by age(<50 and≥50 years).Specifically in the group aged under 50 years,rate of SVR was significantly higher in women than in men(66.7%vs.38.2%,P<0.05).Conclusion:Female gender may predict virological response to standard antiviral therapy in subjects with CHC aged below 50 *** new potent and more expensive antiviral drugs actually available for HCV treatment,it could be useful to identify candidates firstly eligible to therapy.
