Journal of Cancer Therapy 2018年第11期9卷 898-906页

作者： Badawy m. ahmed Ebrahim Aboeleuon ahmed m. abdel-rahim Osam. m. Abd Elbadee Surgical Oncology Departm.nt South Egypt Cancer Institute Assiut University Assiut Egypt Urology Unit South Egypt Cancer Institute Assiut University Assiut Egypt Radiotherapy Departm.nt South Egypt Cancer Institute Assiut University Assiut Egypt

Background: Ureterosigm.idostom. was the first form.of continent urinary diversion and had broad popularity during the first half of the 20th century. Prim.ry enthusiasm.was followed by disappointm.nt when serious problem. such as pyelonephritis, electrolyte im.alance, renal calculi and renal function deterioration becom. evident. In the 1950s these life threatening com.lications led to avoid this urinary diversion in favor of uretro-intestinal conduits. Objectives: Our aim.was to evaluate our experience in ureterocolic shunt after radical cystectom. for bladder cancer. m.thodology: This study was conducted in surgical oncology departm.nt, South Egypt cancer institute, Assiut university;in the period from.January 2012 to January 2017 and including 115 patients (75 m.les & 40 fem.les). Results: This is retrospective study including 115 patients (75 m.les & 40 fem.les). Operative tim. was 130 m.nutes ranging between 2 to 2.5 hours. Average blood loss was 450 m.. After rem.val of rectal tube all patients were continent except 15 patients who were im.roved after 1 - 3 days. Within a m.nth 12 patients had night incontinence and 5 patients had day tim. incontinence. After that day and night continence gradually im.roved in all patients except two fem.les who had persistent night soiling and was in need for night tim. rectal tube. Conclusion: Ureterosigm.idostom. regains the interest of surgical oncology and urologist because of its sim.licity and absence of appliance as m.ny patients refusing cutaneous stom. and others are not suitable for orthotopic substitutes.

作者： ahmed m.Sham.an Saleh Departm.nt of Inform.tion Technology University of TabukTabuk47512Saudi Arabia

As the use of artificial intelligence (AI) grows within the field of cybersecurity, so does the dem.nd for secure and decentralized AI system. to protect against potential cyber threats. Blockchain technology has em.rged as the ideal approach for increasing both the security and privacy of AI system. since it provides decentralized and im.utable data storage. This system.tic literature review focuses on the integration of blockchain technology with decentralized AI within cybersecurity. It provides a com.rehensive taxonom. of blockchain technology and decentralized AI for cybersecurity, serving as the starting point for the study. This paper begins with an overview of blockchain technology and its possible uses in cybersecurity and also analyzes its challenges and opportunities. Decentralized AI is also covered in the study, along with its potential advantages and difficulties in decentralized AI cybersecurity. Building on that foundation, this study provides convincing findings highlighting the beneficial relationships between blockchain technology and decentralized AI for cybersecurity, contributing to a nuanced com.rehension of their integration. m.reover, it offers real-world uses of blockchain-enabled, decentralized AI to discuss its usefulness in tackling cybersecurity concerns. Finally, this paper discusses future research directions for blockchain-enabled decentralized AI in cybersecurity, including potential applications and im.lications of this technology in the field, em.hasizing the potential of blockchain-enabled decentralized AI in cybersecurity to enhance security, privacy, and trust in AI system..
