Drying of sugar cane bagasse was theoretically and experimentally studied ina cyclone. The experiments were carried out using hot air as drying agent. The influence of thecyclone conical part was studied. It was shown that the conical part has a great influence on theparticle residence time and, consequently, on moisture reduction. Experimental results were alikeindustrial ones. CFX 4.4 from AEA Technology was used to simulate some experiments. Simulated andexperimental results were close and showed that the presented model leads to a good prediction.

Case Report： Myxoid Liposarcoma in Retroperitoneum

引用

Journal of Pharmacy and Pharmacology 2018年第6期6卷 587-594页

作者： Janaina gomes da Silva Cirqueira jefferson luiz Rodrigues Nascimento Paulo Henrique de Sousa Fernaxldes Department of Surgery Federal University of Uberlandia Clinical Hospital of Federal University of Uberlandia Uberlandia - MG38402-022 Brazil

Liposarcoma is a malignant neoplasm of mesodermal origin, which among sarcomas, 10% to 20% are located in the retroperitoneum. The case presented shows a 50-year-old male patient who initially presented weight loss and abdominal pain in the left iliac fossa. A tumor mass of hardened consistency was palpated in virtually all the abdomen. An abdominal ultrasound and a computed tomography of the abdomen were performed and confirmed the tumor mass. An exploratory laparotomy was performed, with removal of bulky abdominal mass of greasy consistency. A histopathological study of the piece reported myxoid liposarcoma. Clinical and prognostic features, as well as oncologic outcomes, are well known in this group of patients. The patient has been in the outpatient clinic for 7 years without tumor recurrence. Computed tomography is the fundamental study for the diagnosis of imaging. The treatment of choice consists in an aggressive approach aiming the complete resection, which is a major predictor of local and distant recurrence and survival.

Physical Exercise and Gene p53—A Mini Review

Journal of Cancer Therapy 2020年第8期11卷 463-469页

Cancer is a global problem that in addition to physical, emotional and physiological causes economic and social impacts. The p53 gene is a tumor suppressor gene found in many malignant and benign tumors;this has the primary function of keeping cells at rest after damaging to DNA. The p53 acts in the maintenance of cellular homeostasis, mainly through autophagy, playing a role in cell cycle arrest, when necessary, thus avoiding mutated DNA replication. When in the oncogenic environment in many cases it is mutated, losing much of its efficiency allowing tumor development. Studies show that exercise can in the regular part of its pro-autophagic function even in the oncology setting. Stimuli of moderate-intensity aerobic and predominance of submaximal seem to trigger the protective function of p53 in various cancer settings. Among the many changes that these pathology triggers were the objective of this mini review is to relate the changes that exercise generates in p53 protein functions and their possible influence on tumor cells.
