Abstract :
Background and Aim: Hepatocellular carcinoma is one of the most aggressive cancers that represent a global health problem. It is the fifth most common cancer and the second most common cause of cancer related- mortality worldwide. Hence we conducted the current study using high performance- data mining technology to obscure hidden knowledge would be helpful guide for better predication, follow up and best management. Patients and Methods: Retrospectively, 130 Egyptian patients presented with HCC were followed clinically and their data were analysed using high performance technology of data mining intellectual machine learning of Raid I software program. Results: Amazing results were obtained using Knowledge discovered by data (KDD) such as Serum Creatinine and Total Bilirubin should be the best laboratory indicators for HCC progression. AFP may increase not for the HCC itself but for progression cirrhosis. Furthermore HCC biology should be considered than multiplicity. Conclusion: HCC still a major medical concern in Egypt. Data mining programs would be very helpful in such an area of oncology and future medicine.


Can Variceal Band Ligation (VBL) Improve MELD Score for patients awaiting for liver transplantation?

Abstract :
Background: Esophago-gastric varices are abnormal distended veins usually seen in the esophagus (esophageal varices) and less commonly in the stomach (gastric varices) or in other sites (ectopic varices), bleeding such varices prior to liver transplantation may increase the MELD associated co-morbidities and even mortalities, hence Liver operation may cancelled in different situations, Nevertheless (VBL) should be optimized critically to improve overall success. Aim: Evaluated prophylactic (VBL) may have a beneficial role improving MELD score for those awaiting for Liver Transplantation. Methods: prospectively 70 patients; 53 male and 17 female awaiting for liver transplantation aged (18 to 63) year- old (MELD score ranged between 16 to 38, presented with esophageal/ gastric varices with different grades, VBL was done as primary prophylaxis and comparative MELD score was calculated at the time of VBL and 2 weeks further on. Children was excluded from the study, additionally patients beyond Milan HCC criteria and those with contraindication for major surgery were excluded also. Results: MELD score improved post VBL without reported complications, additionally VBL as a primary prophylaxis was a corner stone procedure saving those with large varices against bleeding may affect the overall operation prognosis, Mean, Median and SD before and after VBL was; (18.9,19.2, 6.02) and (16.9,15.9,6.5) respectively. Conclusion: Cirrhotic patients presented with large esophageal varices (LEVs) prepared for liver transplantation should receive variceal band ligation (VBL) prior to surgery, should decrease associated co-morbidities. MELD score have been improved totally post (VBL), but statistically showed no significant importance.


Hyperthermic effects of cobalt ferrite nanoparticls on adipose cells

R. A. Hassan,
Abstract :
Abstract: Hyperthermia therapy is a medical treatment based on the exposition of body tissue to slightly higher temperatures than physiological to damage and kill cells. Magnetic nanoparticles possess unique properties which can be applied in nanomedicine, they address targets such as cellular therapy, tissue repair, nanobiosensors, drug delivery, magnetic resonance imaging and magnetic fluid hyperthermia. In this work, cobalt ferrite nanoparticls (CFNP) were selectively synthesized with narrow size distribution using chemical precipitation methods. The obtained powder was calcined at 600 C. The sample which characterized by Transmission Electron Microscopy (TEM)confirmed the formation of single-phase CFNP in the range 1025 nm. Localized magnetic particle hyperthermia treatment using ferrimagnetic nanoparticles continue to be an active area of medical research. So, homemade induction heater was designed. The coil was designed to be capable of generating high frequency, strong alternative magnetic fields. The CFNP hyperthermia application in medical was in vitro studied using samples of rabbits Subcutaneous adipose cells. The adipose cells microscopic imaging data as well as the bio distribution results of hyperthermic CFNP content sample showing decreasing the number of subcutaneous adipocyte cell by 23.9 %. In conclusion the preliminary new results for nanoparticles bearing a CFNP core justify further investigations towards potential hyperthermia slimming applications.
