Free cholesterol is demonstrated in formalin-fixed frozen sections when treated successively by digitonin, alcohol-ether, and the Schultz technique, in which circumstances cholesterol esters are not visualized. Cholesterol esters and free cholesterol are both demonstrated in comparable sections treated by the Schultz method alone, so that the difference between such sections indicates the sites...

BACKGROUND BCG, a potent inducer of Th1 immune response, has been suggested to suppress Th2 response which is known to mediate IgE-mediated allergic disorders, in particular allergic asthma. Schultz-Dale reaction is known to be a model of IgE-mediated hypersensitivity. This study was done to investigate whether BCG infection suppresses the Schultz-Dale reaction by inhibiting Th2 response and al...

For a large class of finite-range quantum spin models with half-integer spins, we prove that uniqueness of the ground state implies the existence of a low-lying excited state. For systems of linear size L, of arbitrary finite dimension, we obtain an upper bound on the excitation energy (i.e., the gap above the ground state) of the form (C logL)/L. This result can be regarded as a multi-dimensio...

In 1982 Pimsner and Voiculescu computed the K0and K1-groups of the reduced group C∗-algebra C∗ red(Fk) of the free group Fk on k generators and settled thereby a long standing conjecture: C∗ red(Fk) has no projections except for the trivial projections 0 and 1. Later simpler proofs of this conjecture were found by methods from K-theory or from non-commutative differential geometry. In this pape...

The genus Tortula includes about 114 species in the world and 18 species were found in Iran. In the present paper, T. vahliana (Schultz) Mont. is reported for the first time from Iran.

group of 35 exceptional flies exhibiting variegated type position effects at the A light locus (lt:2-55.0) has been produced, and its analysis is the subject of this paper. Variegation at It has been shown by SCHULTZ and DOBZHANSKY (1934) and further studied by MORGAN, BRIDGES and SCHULTZ (1932, 1935), MORGAN, SCHULTZ and CURRY (1941), MORGAN and SCHULTZ (1942) and SCHULTZ (1936, 1941). However...

A generalization of the Lieb-Schultz-Mattis theorem to higher dimensional spin systems is shown. The physical motivation for the result is that such spin systems typically either have long-range order, in which case there are gapless modes, or have only short-range correlations, in which case there are topological excitations. The result uses a set of loop operators, analogous to those used in ...
