To the Editor : Barcelona Clinic Liver Cancer(BCLC) Stage C hepatocellular carcinoma(HCC) with vascular invasion has been considered unresectable. However, the curative rate from systemic treatment is rather dismal. Even with the use of immunotherapy, complete remission is less than 10% [ 1 ]. on the contrary, recent advances in transplant oncology, especially in the application of liver transplant-related surgical techniques in complex liver resections, make the operation possible for patients with locally advanced HCC who were previously considered to be unresectable [ 2 ]. We hereby present the surgical management of a patient with giant HCC in right liver lobe with inferior vena cava(IVC) invasion.

(1→3)-□-glucan is a core structure in mushroom polysaccharide, which claim to posses anticancerous and immunomodulatory properties. The ability to identify (1→3)-□-glucan in mushroom polysaccharide not only provide useful information on the structural composition of the mushroom polysaccharide, but facilitate us to identify the potential anticancerous and immunomodulatory active *** limulus factor G test, we detected (1→3)-□-glucan in 27 polysaccharides extracted from 19 edible or medicinal mushrooms species. The result show that (1→3)-□-glucan exists in all mushroom polysaccharide extracts but its content varies extremely depends on the mushroom species or the part of mushroom and the degree of purification. our data show the mean of (1→3)-□-glucan in these mushroom polysaccharides is 34.8%. Nine mushroom polysaccharide extracts from L. edodes, S. commune, C. versicolor, V. volvacea, C. comatus, G. frondosa, L. shimeji have superior (1→3)-□-glucan contents than the others. our study demonstrates that limulus Factor G test is a quick and convenient method for detecting (1→3)-□-glucan content in crude mushroom polysaccharide extracts.

CLEAN ENERGY 2024年第3期8卷 116-126页

作者： Martinez, Raymond daniel Rodriguez Univ Metropolitana Fac Engn Dept Ind Prod Caracas 1073 Venezuela

Developing a sustainable energy model is imperative considering the current trend towards decarbonizing sectors worldwide. For this purpose, Venezuela was used as a reference to propose an energy model focused on taking advantage of plant photosynthesis through microbial-vegetable fuel cells together with an agro-photovoltaic system to enhance energy and agricultural production. Energy production from the cells was estimated using an average power density of 264 mW/m(2) over 4% of the areas destined for crops in the entire Venezuelan region, obtaining an annual production of 19.889 GWh/year. In contrast, the energy production of the agro-photovoltaic system was modelled using PVsyst software on 50% of the area used for the cells distributed throughout the states of Anzo & aacute;tegui, Gu & aacute;rico, Monagas and Portuguesa according to their meteorological conditions, solar irradiation and agricultural activity, resulting in 3 703 417 GWh/year. The resulting whole system proved to be able to cover >10 times the installed electricity generation capacity at a national level and, together with the tremendous scalability of the microbial fuel cells, it shows that Venezuela has a high potential for the production and distribution of clean energy.
