| 1 | Population-based epidemiology,risk factors and screening of intraductal papillary mucinous neoplasm patients显示文摘Intraductal papillary mucinous neoplasm(IPMN) was first recognized in the 1980s with increasing publications over the last decade as the incidence increased sharply,especially at tertiary-care referral centers.Populationbased studies have estimated the age and sex-adjusted cumulative incidence of IPMN to be 2.04 per 100 000 person-years(95% conf idence interval:1.28-2.80).It is now understood that IPMN can be classified anywhere along the spectrum of the adenoma to carcinoma sequence and often harbors mutations in genes such as KRAS early in the disease process.Many patients are diagnosed incidentally after imaging of the abdomen for other diagnostic purposes.Patients that present with a history of symptoms such as pancreatitis and abdominal pain are at high risk of harboring a malignancy.Clini-copathologic features such as involvement of the main pancreatic duct,presence of mural nodules,and side branch disease > 3.0 cm in size may indicate that there is an underlying invasive component to the IPMN.In addition,the incidence of extra-pancreatic neoplasms is higher in patients with IPMN,with reported rates of 25% to 50%.There are no current screening recommendations to detect and diagnose IPMN but once the diagnosis is made,screening for extrapancreatic neoplasms such as colon polyps and colorectal cancer should be considered.Surgical resection is the recommend treatment for patients with high-risk features while close observation can be offered to patients without worrisome signs and symptoms of carcinoma. | Saboor Khan Guido Sclabas Kaye M Reid-Lombardo | 2010 | World Journal of Gastrointestinal Surgery2010，2，10： | 2 |

| 5 | Synthesis and Thermal Characterization of Solar Salt-Based Phase Change Composites with Graphene Nanoplatelets显示文摘Thermal energy storage(TES) systems use solar energy despite its irregular availability and day-night temperature difference.Current work reports the thermal characterizations of solar salt-based phase change composites in the presence of graphene nanoplatelets(GNP).Solar salt(60:40 of NaNO_(3):KNO_(3)) possessing phase transition temperature and melting enthalpy of 221.01℃ and 134.58 kJ/kg is proposed as a phase change material(PCM) for high-temperature solar-based energy storage applications.Thermal conductivity must be improved to make them suitable for widespread applications and to close the gap between the system needs where they are employed.GNP is added at weight concentrations of 0.1%,0.3%,and 0.5% with solar salt using the ball milling method to boost its thermal conductivity.Morphological studies indicated the formation of a uniform surface of GNP on solar salt.FTIR spectrum peaks identified the physical interaction between salt and GNP.Thermal characterization of the composites,such as thermal conductivity,DSC and TGA was carried out for the samples earlier and later 300 thermal cycles.0.5% of GNP has improved the thermal conductivity of salt by 129.67% and after thermal cycling,the enhancement reduced to 125.21% indicating that thermal cycling has a minor impact on thermal conductivity.Phase change temperature decreased by around 2.32% in the presence of0.5% GNP and the latent heat reduced by 4.34% after thermal cycling.TGA thermograms depicted the composites initiated the weight loss at around 550℃ after which it was rapid.After thermal cycling,the weight loss initiated at ~40℃ lower compared to pure salt,which was found to be a minor change.Thermal characterization of solar salt and GNP-based solar salt composites revealed that the composites can be used for enhanced heat transfer in high-temperature solar-based heat transfer and energy storage applications. | Pethurajan VIGNESHWARAN Saboor SHAIK Sivan SURESH Müslüm ARICI Asif AFZAL | 2024 | Journal of Thermal Science2024，33，2： | 0 |
