The human gene for mannan-binding lectin-associated serine protease-2 (MASP-2), the effector component of the lectin route of complement activation, …
2001
The proteases of the lectin pathway of complement activation, MASP-1 and MASP-2, are encoded by two separate genes. The MASP1 gene is located on chromosome 3q27, the MASP2 gene on chromosome 1p36.23-31. The genes for the classical complement activation pathway proteases, C1r and C1s, are linked on chromosome 12p13. We have shown that the MASP2 gene encodes two gene products, the 76 kDa MASP-2 serine protease and a plasma protein of 19 kDa, termed MAp19 or sMAP. Both gene products are components of the lectin pathway activation complex. We present the complete primary structure of the human MASP2 gene and the tight cluster that this locus forms with non-complement genes. A comparison of the …
Identification of Leguminosae gums and evaluation of carob-guar mixtures by capillary zone electrophoresis of protein extracts.
2002
A procedure for the extraction and capillary zone electrophoresis (CZE) separation of proteins from carob, guar and tara gums in a background electrolyte (BGE) of pH 9 containing 0.1% polyvinyl alcohol is described. The CZE protein profiles exhibit characteristic peaks for each one of the Leguminosae gums, which can be used to construct models capable of identifying samples of carob, guar and tara gums, and predicting the guar content in binary carob-guar mixtures of different geographical origin and harvested in different years. The classification and prediction models are constructed by using linear discriminant analysis (LDA) and multiple linear regression (MLR), respectively. An excelle…
Nomination for inscription on the World Heritage List Unesco. Arab-Norman Palermo and cathedral churches of Cefalù and Monreale
2012
Il dossier di candidatura per l'iscrizione nella WHL rappresentano l’insieme degli edifici costituenti l’itinerario arabo normanno rappresentano un eccezionale valore universale come esempio di convivenza e interazione tra diverse componenti culturali di provenienza storica e geografica eterogenea (sincretismo culturale). Tale fenomeno ha generato uno stile architettonico originale in cui sono mirabilmente fusi elementi bizantini, islamici e romanici, capace di volta in volta di prodursi in combinazioni uniche, di eccelso valore artistico e straordinariamente unitarie
Natural resins: chemical constituents and medicinal uses
2011
Plants and their exudates are used worldwide for the treatment of several diseases and novel drugs continue to be developed through phytochemical research. There are more than 20,000 species of high vegetables, used in traditional medicines that are sources of potential new drugs. Following the modern medicine and drug research advancing, chemically synthesized drugs have replaced plants as the source of most medicinal agents in industrialized countries. However, in developing countries, the majority of the world’s population cannot afford pharmaceutical drugs and use their own plant based indigenous medicines. Several exudates from plants are well-known in folk medicine since ancient time,…
Isolation and characterization of anavirulent Candida albicansyeast monomorphic mutant
2003
Mutagenesis of Candida albicans strain ATCC 26555 with N-methyl-nitro-N-nitrosoguanidine followed by plating on solid yeast nitrogen base-N-acetylglucosamine medium at 37 degrees C yielded colony morphology variants that were characterized as forming smooth colonies, in contrast to the rough colonies formed by the parental strain. One yeast monomorphic mutant, CAL4, was studied in detail. Strain CAL4 is defective in filamentous growth, unable to form hyphae or pseudohyphae in vivo and in vitro. These filamentous structures are not elicited by commonly used external stimuli such as serum. The mutant had no obvious alterations in its mannan, glucan or chitin content. The total quantity of non…

Structural and functional diversity of the lectin repertoire in teleost fish: Relevance to innate and adaptive immunity
2011
Protein–carbohydrate interactions mediated by lectins have been recognized as key components of innate immunity in vertebrates and invertebrates, not only for recognition of potential pathogens, but also for participating in downstream effector functions, such as their agglutination, immobilization, and complement-mediated opsonization and killing. More recently, lectins have been identified as critical regulators of mammalian adaptive immune responses. Fish are endowed with virtually all components of the mammalian adaptive immunity, and are equipped with a complex lectin repertoire. In this review, we discuss evidence suggesting that: (a) lectin repertoires in teleost fish are highly dive…
Seasonal pattern of mannitol and malate accumulation in leaves of two manna ash species (Fraxinus ornus L. and F. angustifolia Vahl) growing in Sicily
2002
The content of mannitol and malate was assayed enzimatically during spring, summer and autumn, in leaves of two species of ash traditionally cultivated in Sicily for the extraction of manna. The results suggest that in these species, under the local field conditions, mannitol has a more relevant role than malate in the response to summer drought.
