The fractionation and characterization of cereal proteins may be among the most difficult problems in biochemistry: these proteins are heterogeneous. have unusual solubility characteristics. and have marked tendencies to aggregate. both covalently and noncovalently. Recent reviews (Bietz and Huebner 1980. Kasarda et a11976. Khan and Bushuk 1979. Miflin and Shewry 1979. Wall 1979) demonstrate th...

Biogeosciences Discussions This discussion paper is/has been under review for the journal Biogeosciences (BG). Abstract The Seine watershed has long been the food-supplying hinterland of Paris, providing most of the animal and vegetal protein consumed in the city. Nowadays, because of the land specialisation of agriculture made possible by the shift from manure-based to synthetic nitrogen ferti...

OBJECTIVE The aim of this research was to describe the variation in bread consumption within social classes and to link this consumption to health-related lifestyles in Finland from 1978 until 1998. DESIGN A cross-sectional survey on health-related behaviour and socio-demographic factors has been conducted annually since 1978. SETTING Mailed questionnaire. SUBJECTS A random sample of 5000...

Aflatoxins (AFs), ochratoxin A (OTA) and zearalenone (ZEN) were analysed in 237 breakfast cereal samples collected from central areas of Punjab, Pakistan. According to the results, 41% of the samples were found contaminated with AFs, out of which 16% and 8% samples were found to be above the European Union (EU) maximum content for AFB1 and total AFs, respectively. About 48% samples were found c...

INTRODUCTION Acrylamide, produced during thermal processing of carbohydrate-rich foods, is classified as "probably carcinogenic to humans" by the International Agency for Research on Cancer. OBJECTIVE The aim of this study was to determine acrylamide levels in biscuits and breakfast cereals considering the widespread use of these products for all ages. METHOD Acrylamide determination was ca...

In tetraploid rye with single-substitution wheat chromosomes - 1A, 2A, 5A, 6A, 7A, 3B, 5B, 7B - chromosome pairing was analysed at metaphase I in PMCs with the C-banding method. The frequency of univalents of chromosome 1A was considerably higher than that of the other four wheat chromosomes of genome A (6A, 5A, 7A and 2A). Among chromosomes of genome B, the lowest mean frequency of univalents ...

Little is known about the natural history of the Sphaerodactylus species endemic to the three islands located in the Mona Passage separating the Greater Antillean islands of Hispaniola and Puerto Rico. In this study, parts of two mitochondrial genes, 16S rRNA and 12S rRNA, were sequenced to determine the relationships between the sphaerodactylids that live in the Mona Passage and other Caribbea...

The Seine watershed has long been the foodsupplying hinterland of Paris, providing most of the animal and vegetal protein consumed in the city. Nowadays, the shift from manure-based to synthetic nitrogen fertilisation, has made possible a strong land specialisation of agriculture in the Seine watershed: it still provides most of the cereal consumed by the Paris agglomeration, but exports 80 % o...

Bowman-Birk Inhibitors (BBIs) are a well-known family of plant protease inhibitors first described 70 years ago. BBIs are known only in the legume (Fabaceae) and cereal (Poaceae) families, but peptides that mimic their trypsin-inhibitory loops exist in sunflowers (Helianthus annuus) and frogs. The disparate biosynthetic origins and distant phylogenetic distribution implies these loops evolved i...

a survey of cereal fields of khuzestan province during 2008-2011 revealed that cereal cyst nematodes (ccns) are widely distributed in this region. the ccns were present in 37 and 35% of the 200 samples collected from wheat and barley fields respectively. the species were identified as heterodera avenae type b and h. filipjevi the morphological and morphometric identifications of which were conf...
