(5) This finding also suggests that the Hex, Mut, and PMS systems evolved from a common ancestor and that functionally similar mismatch repair systems could be widespread among procaryotic as well as eucaryotic organisms.
(6) The greatest amount of hex S activity was found in fibroblast, but it was also observed in lesser amounts in liver, kidney, intestine and placenta.
(7) At low pH, two of the latter mabs reacted only with Hex B, and it was, therefore, possible to develop enzyme immunoassays for the specific determination of Hex A and Hex B.
(8) The competitive ganglionic nicotinic blocking agent, HEX, on the other hand, inhibited both the increased locomotion produced by CRF in the home cage and also the decreased locomotion induced by CRF in the modified open field.
(9) Hex 70-Inv and Hex 532-Inv, like endogenous lysosomal enzymes, were subject to developmentally induced secretion.
(10) A hexose (Hex)2-3 branch is attached to the heptose linked directly to KDO and a GalNAc-Hex3, GlcNAc, and PEA are separately attached to the second heptose.
(11) The commonly used screening test for detection of Tay-Sachs disease (TSD) carriers is the serum Hex heat inactivation method (HIM), which is based on the assumption that Hex A is the only thermolabile component of Hex; However, in the presence of thermolabile Hex B, HIM could lead to false-negative results.
(12) HEX(C) is shown to differ from HEX(A) and HEX(B) in substrate specificity, molecular size and affinity for Concanavalin-A.
(13) The activities of beta-hexosaminidase (HEX), a lysosomal glycosidase, were studied in serum (sHEX) and urine (uHEX) among men with various drinking habits.
(14) The Hex treated dogs and cats exhibited a fall of MAP and CBF with enhancement of CVR.
(15) The electrophoretic pattern of human fibroblast extracts displays three bands (cathode to anode) of hexosaminidase: Hex B, Hex A, Hex C in normal strains, only one B band in Tay-Sachs strains, and only one C band in Sandhoff strains.
(16) Though monkey tissues also cross-reacted with human seminal plasma Hex-antisera, mouse, rat, and goat testis and epididymis extracts failed to show any cross-reaction.
(17) Hex S, the major residual beta hexosaminidase activity present in tissues, fluids, and cultured skin fibroblasts of patients with type 0 GM2 gangliosidosis, was isolated and characterized biochemically and immunologically.
(18) The persistence of a second major hexosaminidase isozyme, HEX B, does not protect against the lethal accumulation of GM2 ganglioside in the central nervous system.
(19) The results suggest that, in the patient's fibroblasts, a defect in beta-chain synthesis or processing precludes the self-association of beta-chains to form Hex B, but does not prevent the association of alpha- and beta-chains to form Hex A.

Example Sentences:
