    Description / Table of Contents: Résumé Sur la base de données anatomiques obtenues lors de précédents travaux sur l'anatomie vasculaire de la main, l'architecture vasculaire palmaire a été étudiée sur 60 extrémités supérieures de cadavres d'adultes, non embaumés. Chaque paume a été divisée en 64 carrés par 8 sections sagittales et 8 sections transversales. L'architecture vasculaire à l'intérieur des carrés et les relations artérielles entre eux ont été étudiées et mesurées par angiographie, dissection au microscope opérateur et reconstruction computérisée en 3D. Les paumes amputées ont été regroupées en 4 types d'après la distribution des vaisseaux sanguins. Les données anatomiques concernant les anastomoses vasculaires sont précisées. Il existe trois zones clés pour l'irrigation de la paume. Leur importance quant à l'irrigation de la main est exposée. Outre la division des paumes amputées transversalement en 4 types, le programme de réparation de vaisseaux dans les 4 types d'amputations obliques communes de la paume et aussi discuté.
    Notes: Summary Based on the anatomic data obtained from earlier studies on the vascular anatomy of the hand, the vascular architecture in the palm of the hand was studied on 60 sides of unembalmed adult upper extremities. Each palm was divided into 64 squares by 8 sagittal and 8 transverse sections. The vascular architecture in these squares and the arterial relations between them were observed and measured by angiography, operative microscopic dissection and computerised three-dimensional reconstruction. According to the pattern of the blood-vessels, the amputated palms can be classified into 4 types. The anatomic basis for the vascular anastomosis in each type is defined. There are three key-areas for the blood-supply of the palm and their significance is discussed. Apart from the 4 types of transversely amputated palms, the repair programe of the blood-vessles in 4 types of common obliquely amputated palms are also discussed.

    Description / Table of Contents: Résumé Trente membres supérieurs de sujets adultes ont été étudiés. Les vaisseaux sanguins de la main ont été analysés sur des angiographies, des coupes anatomiques et des dissections sous microscope. Les artères de la paume sont disposées en trois plans dans la partie moyenne, alors que dans les segments sous-jacents, elles sont disposées en deux plans seulement. La disposition des territoires dépendant des aa. radiale et ulnaire n'est pas la même dans chaque plan. Il existe trois voies anastomotiques entre les aa. radiale et ulnaire dans le sens paume-dos de la main. Les possibilités de réimplantation après amputation transpalmaire ont été envisagées grâce à l'étude dynamique de la circulation, à des coupes et à l'analyse des anastomoses artérielles entre ces trois plans.
    Notes: Summary Thirty adult upper extremities were used to study the blood vessels of the hand by angiography, cross-sectional measurement and operative microscopic dissection. The arteries in the middle segment of the palm are arranged in three planes, while in the upper or lower segment there are two planes only. The division of the territories of the radial and ulnar arteries are not same in the three different layers. There are three main anastomotic pathways between the radial and ulnar arteries in the radial-ulnar direction, while in the palmar-dorsal direction there are three anastomotic zones between the palmar and dorsal planes. According to the rate of appearance, sources, cross-sectional area, irrigation territories and anastomoses of the arteries in the three segments, the clinical significance in the reimplantation of the amputated hand through the palm has been discussed.

    Identification of a hybrid-specific expressed gene encoding novel RNA-binding protein in wheat seedling leaves using differential display of mRNA (2000)

    Notes: Abstract A hybrid-specific expressed cDNA fragment, designated as AG5, has been identified in wheat seedling leaves using differential mRNA display. AG5 contains an open reading frame (ORF) encoding 183 amino acid residues. Comparison with amino acid sequences in GenBank revealed that the AG5 protein is homologous to a group of Gly-rich proteins with consensus sequence-type RNA-binding domains (CS-RBD). Structural analysis showed that AG5 protein contains five motifs, including a consensus sequence-type RNA-binding domain near its N-terminus, arginine/aspartic acid repeats and a Gly-rich region in its center, a Cys-X2-Cys-X4-His-X4-Cys (CCHC) zinc finger motif in the Gly-rich region, and TrySer2ArgAsp2Arg repeats towards its C-terminus. Of all previously described RNA-binding proteins, only RZ-1 from tobacco has a similar structure to the AG5 protein, but RZ-1 lacks a TrySer2ArgAsp2Arg repeat motif, indicating that the two proteins may belong to a family of closely related proteins in plants. The possible role of AG5 and its relation to wheat heterosis are discussed.

    Hybrids and backcross progenies between wheat (Triticum aestivum L.) and apomictic Australian wheatgrass [Elymus rectisetus (Nees in Lehm.) A. Löve & Connor]: karyotypic and genomic analyses (1994)

    Notes: Abstract Wheat (Triticum aestivum L., 2n = 6x = 42, AABBDD) florets were emasculated and pollinated using two apomictic wheatgrass [Elymus rectisetus (Nees in Lehm.) A. Love & Connor, 2n = 6x = 42, SSYYWW] accessions, one of which produces 2n pollen. A 2n = 42 (BII) hybrid and four 2n = 63 (B III) hybrids were obtained. The spike morphology of the B II hybrid was intermediate to that of its parents. The pollen mother cells (PMCs) of this hybrid contained on average 38.361 and 1.62 II, which was consistent with its disparate genome composition (ABDSYW). Its pollen failed to stain and no BC1 progeny was obtained. The B III hybrids (reduced egg fertilized with unreduced sperm) were grasslike and had a full complement of E. rectisetus chromosomes, the synapsis of which was slightly impaired by wheat haplome and/or cytoplasm. Their PMCs contained on average 16.30 II, 25.72 I, and 1.54 multivalents (III plus IV). Pollen stainability in these hybrids was low (〈1%), and when they were used as females, one 54- and 60-chromosome BC1 were obtained. A mean of 13.25 II was observed in PMCs of the 54-chromosome BC1 and pollen stainability was 10%. Pollen stainability in the 60-chromosome BC1 was only 5%. The use of 2n-pollen-producing E. rectisetus accession accelerated hybrid and BC1 formation and may accelerate the ultimate transfer of apomixis to wheat.
