Migraine is a very common disorder characterized by the combination of typical headache with associated autonomic symptoms and/or the presence of aura. Considerable advances have been made in recent years to understand the pathophysiology of migraine, which has led to improved treatment options for the acute migraine attack as well as migraine prophylaxis. Unfortunately, preventive treatment is...

In 1991 the Clinical Trials Subcommittee of the International Headache Society (IHS) developed and published its first edition of the Guidelines on controlled trials of drugs in episodic migraine because only quality trials can form the basis for international collaboration on drug therapy, and these Guidelines would 'improve the quality of controlled clinical trials in migraine'. With the curr...

UNLABELLED Migraine can be triggered by many factors such as stress, sleep, fasting and environmental causes. There are few studies that evaluated migraine trigger factors in the adolescent population. METHODS A total of 100 participants from 10 to 19 years were subjected to a detailed headache questionnaire, with demographic and clinical data, and a headache diary including trigger factors d...

Subcutaneous inoculation of Epstein-Barr virus (EBV) transformed peripheral blood B-lymphocytes (PBL) from an untreated chronic lymphocytic leukemia (CLL) patient produced progressively growing lethal tumors in 4 of 11 whole body irradiated (440 rads) nude mice. In one tumor bearing mouse there was splenomegaly and generalized enlargement of lymph nodes. Chromosomal analysis and membrane immuno...

OBJECTIVE The aim of the current study is to test whether immortalized B-lymphocyte cell line via Ebstein-Barr virus (EBV) transformation is feasible and can be an unlimited source of genome wide study. METHODS We obtained peripheral whole blood from 5 ovarian cancer patients and immortalized the B-cell lines using EBV transformation. The success rate was analyzed and the bio-identity of the ...

HGPRTase-deficient EBV-transformed B cell lines were shown to be effective fusion partners with mitogen-activated human B cells for the construction of Ig-producing human B cell hybridomas. In a series of experiments using these lines and B cells from several tissue sources, approximatley 20% of the cultures plated were consistently positive for growth after hypoxanthine-aminopterin-thymidine s...
