　　According to the 22nd edition of "The American Illustrated medical Dictionary",dialysis[dia=through,apart,across or between;lysis=to loose]is defined as the process of separating crystalloids and colloids in solution by the differences in their rates of diffusion through a semipermeable membrane:crystalloids pass through readily,colloids very slowly or not at all(1).……

In this paper,we propose a new approach to tackle the separability problem for bipartite qudit *** is based on the majorana representation which allows to represent a N-spinors(qudit)as a symmetric state of N spin-1/*** also discuss how we can exploit such representation and the notion of the biseparability of multipartite qubit states in the sense to establish new criteria of the separability problem based on the PPT and concurrence.

Objective: Panitumumab administered as monotherapy in colorectal cancer(CRC) has shown response and disease stabilization rates of approximately 30%. The current study aimed to evaluate the progression-free survival(PFS) and overall survival(OS) of patients with metastatic colorectal cancer(mCRC) treated with panitumumab every 3 weeks as a second line ***: This study is a retrospective analysis of 18 patients, aged more than 18 years, with wild-type KRAS exon 2 mCRC treated with panitumumab as a second-line single agent after progression on first-line ***: The median number of courses received was 10(range, 4-29), and the median duration of treatment was 30 weeks(range,12-96 weeks). After a median follow-up period of 13 months, the median PFS was 6 months(range, 4.3-7.7 months) and the median OS was 11 months(range, 7.4-14.5 months). The median PFS was 4 months for patients with months(range, 4.5-7.5 months) for patients with ≥ grade 2 skin rash(P=0.05). The median OS was 9 months(range, 6.4-11.5months) and 14 months(range, 11.6-16.3 months) for the two groups of patients(P=0.002).Conclusions: Panitumumab given every 3 weeks is effective and well tolerated in patients with advanced CRC that progressed after standard chemotherapy.
