Autoradiographic studies of tn/tn mouse embryos.
High-resolution autoradiographic studies were used to determine whether t12/t12 and tw32/tw32 mouse embryos synthesize the excessive lipid which distinguishes these embryos prior to their death. The studies show that the tn homozygotes synthesize neutral lipid which is stored in intracellular lipid droplets. Cholesterol and phospholipid precursors are not incorporated into these droplets.
متن کاملNonstandard Drinfeld-Sokolov reduction
Subject to some conditions, the input data for the Drinfeld-Sokolov construction of KdV type hierarchies is a quadruplet (A,Λ, d1, d0), where the di are Z-gradations of a loop algebra A and Λ ∈ A is a semisimple element of nonzero d1-grade. A new sufficient condition on the quadruplet under which the construction works is proposed and examples are presented. The proposal relies on splitting the...
متن کاملQuantum Drinfeld Hecke Algebras
We consider finite groups acting on quantum (or skew) polynomial rings. Deformations of the semidirect product of the quantum polynomial ring with the acting group extend symplectic reflection algebras and graded Hecke algebras to the quantum setting over a field of arbitrary characteristic. We give necessary and sufficient conditions for such algebras to satisfy a Poincaré-Birkhoff-Witt proper...
متن کاملMEASLES EPIDEMICS TN KERMAN, IRAN
In early 1990, an outbreak of measles occurred in Kerman, (population 257, 284) Iran. Overall, 475 cases were identified and four died (case fatality ratio 5.4 per thousand). Illness was limited primarily to children below 15 years of age 166 (22.3%) were in children under five, 573 (77%) between 5-14 and six (0.8%) above 15 years of age. The age of the cases ranged from five months to 35 y...
