One hundred and five cases of various human lung neoplasms were studied immunohistochemically using monoclonal antibodies recognizing the antigens, Le(x), sialylated Le(x) (SLEX), Le(a), and sialylated Le(a) (SLEA). Of the 92 lung cancers examined for antigen expression SLEX was detected in 57% (52 cases), Le(x) in 42% (39), SLEA in 36% (33), and Le(a) in 23% (21). None of these antigens were e...

In this paper we investigate the properties and linear stability of travelling premixed combustion waves and the formation of pulsating combustion waves in a model with two-step chain-branching reaction mechanism. These calculations are undertaken in the adiabatic limit, in one spatial dimension and for the case of arbitrary Lewis numbers for fuel and radicals. It is shown that the Lewis number...

PURPOSE In Lewis rats, S-antigen-induced intraocular inflammation, which occurs initially in the retina, is mediated by T cells requiring major histocompatibility complex (MHC)-restricted antigen presentation. In such organ-specific inflammation, antigen presentation may take place at the site of the initial inflammatory response. In the present study an attempt was made to determine the presen...

A fully-implicit numerical method based upon adaptively refined meshes for the thermal-solutal simulation of alloy solidification in 2D is presented. In addition we combine an unconditional stable second-order fully-implicit time discretisation scheme with variable step size control to obtain an adaptive time and space discretisation method, where a robust and fast multigrid solver for systems ...

BACKGROUND Lewis y antigen is difucosylated oligosaccharide and is carried by glycoconjugates at cell surface. Elevated expression of Lewis y has been found in 75% of ovarian tumor, and the high expression level is correlated to the tumor's pathological staging and prognosis. This study was to investigate the effect and the possible mechanism of Lewis y on the proliferation of human ovarian can...

By employing a chiral Lewis base as the catalyst, enantioselective hydrosilylation of N-(1,2-diarylethylidene)arylamines was realized. The reactions proceeded smoothly to afford various chiral 1,2-diarylethanamines with good yields (up to 99%) in good enantioselectivities (up to 98%). Furthermore, one of the products was employed in the synthesis of a pharmaceutical substance.

PURPOSE We compared three rat strains to determine if different strains develop early-stage diabetic retinopathy or sensory neuropathy at different rates. METHODS Sprague Dawley, Lewis, and Wistar rats were made diabetic with streptozotocin. Diabetic and nondiabetic animals had retinal vascular pathology measured at eight months of diabetes. The number of cells in the retinal ganglion cell la...

The chemistry of frustrated Lewis pairs derived from N-heterocyclic carbenes and a number of Lewis acids has been probed. The combination of 1,3-bis[2,6-(di-iso-propyl)phenyl]-1,3-imidazol-2-ylidene (IDipp) (1) with B(C6F5)3 was shown to give the classical Lewis acid-base adduct (IDipp)B(C6F5)3 (2) which was unreactive. In contrast, the combination 1,3-di-tert-butyl-1,3-imidazol-2-ylidene (3) w...

Garnet Type Solid Electrolytes In article number 2203897, Venkataraman Thangadurai and co-workers report the use of an AlCl3 Lewis acid fluoroethylene carbonate dual additive based non-aqueous liquid electrolyte stabilizing garnet solid-liquid interphase, towards improved durability high critical current density for hybrid solid-state lithium metal batteries.
