When suitable, surgery still remains the therapeutic option to be preferred for patients carrier of colorectal liver and lung metastases. Since thoracophrenolaparotomy should be helpful during liver resection for some of these patients, simultaneous removal of right lung metastases can be proposed through this approach. Eleven consecutive patients（median age of 53 years） carrier of colorectal liver and lung metastases, underwent single session surgical resection of both liver and right lung lesions by means of J-shaped thoracophrenolaparotomy. The median number of liver metastases removed was 5（range 2-30） and of lung metastases removed was 2（range 1-3）. Lung metastases were located in the upper lobe in 1 patient, in the middle lobe in 2, in the lower lobe in 6, and in the upper and lower lobe in 2. Mortality and major morbidity were nil. Two patients had a minor morbidity： one had wound infection and bile leakage treated conservatively and the other had transient fever. Mean overall survival was 24.4 months. An aggressive surgical approach should be undertaken for colorectal metastases： in case of multifocal liver disease with complex presentations, J-shaped thoracophrenolaparotomy could be considered as safe approach for combined liver and right lung metastasectomies.

Aluminum and copper matrix nanocomposites reinforced by graphene nanoplatelets （GNPs） were successfully fabricated by a wet mixing method followed by conventional powder metallurgy. The uniform dispersion of GNPs within the metal matrices showed that the wet mixing method has a great potential to be used as a mixing technique. However, by increasing the GNPs content, GNPs agglomeration was more visible. DSC and XRD of AI/GNPs nanocomposites showed that no new phase formed below the melting point of AI. Microstructural observations in both nanocomposites reveal the evident grain refinement effect as a consequence of GNPs addition. The interfacial bonding evaluation shows a poor interfacial bonding between GNPs and AI, while the interfacial bonding between Cu and GNPs is strong enough to improve the properties of the Cu/GNPs nanocomposites. In both composites, the coefficient of thermal expansion decreases as a function of GNPs while, their hardness is improved by increasing the GNPs content as well as their elastic modulus.

In the May 2022 issue of Annals of Surgery,Albert *** and colleagues reported interesting results on the effect of liver transplantation(LT)experience in performing complex liver resection(CLR)(1).By considering 1,452 LT and 222 CLR over a period of 24 years,performed in a worldwide recognized center for LT and liver surgery,they had 25.2%major complications and 6.3%mortality after ***,they found that the more experience in LT,the less risk of postoperative complications after *** also indicated the cutoff of 95 LT;meaning that at below such number,the rate of complications after CLR significantly increased(1).

Radiofrequency ablation(RFA)currently represents a potentially curative treatment for hepatocellular carcinoma(HCC)in its early stages(1,2).Providing higher rates of complete necrosis of target tumor than other loco-regional therapies(LRTs),RFA plays an important role as bridge therapy to liver transplantation(LT)(3).In the study from Lee and colleagues of the UCLA medical center,published in issue of June 2017 of Hepatology,Authors analyzed the outcome of 121 patients with 156 de-novo HCC treated with RFA as initial stand-alone therapy(4).The study is a fair attempt to analyze the efficacy of RFA as bridge therapy to LT,considering all potential outcome ***,some results passed unnoticed,while instead deserve further discussion.

Cardiac transplantation is currently the preferred choice of treatment for end-stage cardiac disease. Despite great advances have been made in the prevention and treatment of acute transplant rejection, accelerated cardiac allograft vasculopathy （CAV） still limits the long-term success of heart transplantation. CAV is a rapidly progressive form of atherosclerosis described by vascular remodeling of the graft coronary arteries that occurs uniquely in transplant recipi- ents. In the early stages, CAV is characterized by intimal proliferation, while luminal stenosis of epicardial branches, occlusion of smaller arteries and myocardial infarction occur in the later stages.

We review the measurements of the D decay strong-phase parameters based on quantum-correlated D^0D^-0 pairs produced in the e^＋e^→（3770） →D^0D^-0 process, and we discuss their role in the measurements of Cabibbo-Kobayashi-Maskawa angle 7 and D-/9 mixing. In addition, we present estimates of the size of quantum-correlated datasets necessary to support the 7 and charm mixing measurements conducted at the LHCb and Belle Ⅱ experiments. Finally, we review the methods for measuring the D-D^- mixing and cP violation parameters at a high-luminosity charm factory, giving sensitivity estimates.
