Question: Abstract: The authors report on the first case of signet-ring cell lymphoma involving the orbit. This variant of non-Hodgkin's lymphoma contains either vacuolated or eosinophilic cytoplasmic inclusions that squeeze the nucleus to one side of the cell. In this case, the inclusions were eosinophilic and stained positively for PAS, immunoglobulin M (IgM) heavy chain and kappa light chain. Electron microscopy showed granular electron-dense material trapped within distended loops of rough endoplasmic reticulum. Twenty-two cases of signet-ring cell lymphoma previously reported elsewhere in the body are reviewed, and their clinical significance is discussed.
Which is the apt title for the abstract? option1: Signet-ring cell lymphoma in the orbit: a case report and review. option2: A study of the human immune response to Lolium perenne (rye) pollen and its components, Lol p I and Lol p II (rye I and rye II). I. Prevalence of reactivity to the allergens and correlations among skin test, IgE antibody, and IgG antibody data.

Answer: Signet-ring cell lymphoma in the orbit: a case report and review.

Question: Abstract: Frozen cryosections, 8 microns thick, were cut parallel to the surface of porcine skin so as to provide separate samples representing various epidermal layers. These samples were dried, extracted with chloroform-methanol mixtures, and the lipids chromatographed on silica gel plates in different solvent systems. After spraying with sulfuric acid and charring, lipids were quantified using a scanning densitometer. It was thus possible to determine lipid concentrations in 12 consecutive epidermal layers, extending 96 microns into the skin. The phospholipids that were characterized all decreased in concentration toward the surface, whereas the neutral lipids and ceramides all increased. Glucosylceramide and acylglucosylceramide reached a peak concentration in the stratum granulosum and then decreased in the surface layers. Cholesterol sulfate reached a maximum concentration in the deeper stratum corneum and then abruptly decreased in the surface layer. These changes in patterns of lipid concentration are consistent with current theories regarding the formation of a water barrier in the stratum corneum that is composed mainly of neutral lipids, and with a possible function of cholesterol sulfate in cellular adhesion in the stratum corneum.
Which is the apt title for the abstract? option1: Variations in lipids in different layers of porcine epidermis. option2: Monoclonal patent. Hybritech versus Abbott [news]

Answer: Variations in lipids in different layers of porcine epidermis.

Question: Abstract: The T-cell antigen receptor binds antigen in association with a cell surface molecule encoded by the major histocompatibility complex (MHC). MHC restricted recognition of antigen by this receptor leads to the complex pattern of programmed gene expression that characterizes T-cell activation. The eventual understanding of human T-cell function will require the complete elucidation of the structure of the human T-cell antigen receptor. On human T cells, clonally determined, disulphide-linked alpha and beta chains of the receptor are non-covalently and stoichiometrically associated with three additional polypeptides known as the T3 complex. These receptor subunits are glycoproteins of relative molecular mass (Mr) 25,000 (25K) and 20K (gamma and delta) and a non-glycosylated 20K protein (epsilon). Our studies of murine T cells show that the mouse T-cell antigen receptor consists of at least seven distinct polypeptide chains. In addition to clonotypic alpha and beta chains, the murine complex consists of glycoproteins of 26K and 21K and endoglycosaminidase F (endo F)-insensitive polypeptides of 25K, 21K and 16K. The latter, which we have termed zeta (zeta), exists as a homodimer within the complex. The 26K component (gp26) has been shown to be the murine analogue of the human delta chain. Other cross species homologies remain to be established, however none of the described human receptor components appear similar to the murine zeta polypeptide. We report here the use of an antiserum raised against the murine zeta subunit to identify a previously unrecognized component of the human T-cell antigen receptor. This human protein is T-cell specific and biochemically similar to the murine zeta polypeptide.
Which is the apt title for the abstract? option1: A new subunit of the human T-cell antigen receptor complex. option2: Focal fat deposition in axial bone marrow: MR characteristics.

Answer:
A new subunit of the human T-cell antigen receptor complex.
