We show that a quotient group of a CI-group with respect to (di)graphs is a CI-group with respect to (di)graphs. In [1,2], Babai and Frankl provided strong constraints on which finite groups could be CI-groups with respect to graphs. As a tool in this program, they proved [1, Lemma 3.5] that a quotient group G/N of a CI-group G with respect to graphs is a CI-group with respect to graphs provide...

BACKGROUND AND PURPOSE Few dietary protein sources have been studied prospectively in relation to stroke. We examined the relation between foods that are major protein sources and risk of stroke. METHODS We prospectively followed 84 010 women aged 30 to 55 years at baseline and 43 150 men aged 40 to 75 years at baseline without diagnosed cancer, diabetes, or cardiovascular disease. Diet was a...

OBJECTIVE To assess whether the dietary intake of long-chain n-3 polyunsaturated fatty acids from seafood, assessed both directly and indirectly through a biomarker, is associated with a reduced risk of primary cardiac arrest. DESIGN Population-based case-control study. SETTING Seattle and suburban King County, Washington. PARTICIPANTS A total of 334 case patients with primary cardiac arr...

Introduction More than 50,000 people in Germany use a cochlear implant (CI). Potentially, revision surgery may become necessary any patient due to technical defect, medical or other reasons. The aim of the present study is analyze reasons leading CI reimplantation and calculate cumulative survival rate.

Introduction: The use of the latter is available, usually on a paid basis. In practice, five wing indices are most often used to discriminate wings: Ci, Disc.sh., Dbi, Ri, Pci. Due peculiarity structure wings, Ri and especially Disc.sh. determined with significant errors (Std.Err.), which reduces reliability classification as whole. goal work: authors set out find small number identification th...
