Notwithstanding these demands, and the associated high quality of a fledgling facultylevel type, the job starts with some ‘setup’ money for equipping the lab; but next to no means are provided to initiate that ‘research program’ and to sustain it during the years to come. ...
متن کاملApproximation of the yolk by the LP yolk
If n points are sampled independently from an absolutely continuous distribution with support a convex subset of <2, then the center and radius of the ball determined by the bounding median lines (the LP yolk) converge with probability one to the center and radius of the yolk. The linear program of [9] is therefore an effective heuristic for computing the yolk in large samples. This result part...
متن کاملYolk Phosphatidylcholine Bilayers
The activity of (Ca -Mg )ATPase reconstituted into egg yolk phos phatidylcholine liposomes is reduced when the lipid has been oxidized before the reconstitution procedure. It is suggested that the reversible decrease in activity is caused by a decrease of the lipid bilayer thickness due to the shortening of lipid acyl chains during autoperoxidation; the irreversible decrease in the activity is...
متن کاملYOLK SAC TUMOR OF VAGINA
Malignant germ-cell tumors (MGCT) are rare tumors of childhood accounting for less than 3% of pediatric malignancies. Endodermal sinus tumor (EST) forms the most common histologic subtype of MGCT. The vagina is an extremely rare site for GCTs. An 8-month-old female was admitted with a short history of vaginal bleeding, and a mass protruding from the vagina. She was pale and a mass was palpab...
متن کاملStudies on Amphibian Yolk
The yolk platelets of mature eggs and young embryonic cells of all amphibian species studied (Rana pipiens, Triturus pyrrhogaster, Diemictylus viridescens, Rana nigromaculata, and Bufo vulgaris) have a superficial layer of fine particles or fibrils (ca. 50 A in diameter), a central main body with a crystalline lattice structure, and an enclosing membrane approximately 70 A in thickness. Electro...
