The ECG showed normal sinus rhythm at 65 per min., with a very short P-R interval (0.10 sec.). On the fourth beat of the first lead set (simultaneous leads I, II, III), which is marked with an arrow, there is an atrial premature, contraction. This latter beat has a low, rather flat P wave preceding the QRS with a P-R interval of 0.20 sec. The contrast between the sinus beats (with short PR) and...

Leupeptin~ a proteinase inhibitor obtained from culture f i l t rates of Streptomyces sp.~ has been proposed as a valuable agent for the restriction of proteolysis in vivo. We have previously shown tha t mammalian tissues possess an enzymic system that is capable of inactivating leupeptin (Beynon R39 Brown CP & Butler PEr 1981, Acta Biol. Med. Germ. @0, 153%1546). This paper demonstrates the ub...

In Gentiana lutea two varieties are described: G. lutea var. aurantiaca with orange corolla colors and G. lutea var. lutea with yellow corolla colors. Both color varieties co-occur in NW Spain, and pollinators select flower color in this species. It is not known whether a hybridization barrier exists between these G. lutea color varieties. We aim to test the compatibility between flower color v...

The objective of the present study was to make use of efficient molecular marker systems to reveal genetic relationships in traditional and evolved Basmati (EB) and semidwarf non-Basmati (NB) rice varieties. A subset of three rice groups was analyzed by using 19 simple sequence repeat (SSR) loci and 12 inter-SSR-PCR primers. A total of 70 SSR alleles and 481 inter-SSR-PCR markers were revealed ...

In this paper we discuss Kfinneth decompositions for finite quotients of several classes of smooth projective varieties. The main result is the existence o f an explicit (and readily computable) Chow-Kiinneth decomposition in the sense o f Murre with several pleasant properties for finite quotients of abelian varieties. This applies in particular to symmetric products of abelian varieties and a...

For predual categories C andD we establish isomorphisms between opfibrations representing local varieties of languages in C, local pseudovarieties of D-monoids, and finitely generated profinite D-monoids. The global sections of these opfibrations are shown to correspond to varieties of languages in C, pseudovarieties of D-monoids, and profinite equational theories of D-monoids, respectively. As...

A total of 18 rainfed upland New Rice for Africa (NERICA) varieties were categorized as the heavy panicle and low tillering types and early heading, in compared with 32 different varieties. These chromosome components were clarified using 243 SSR markers which showed polymorphism among NERICA varieties and their parents, CG 14 (O. glaberrima Steud.) and one of the recurrent parents, WAB-56-104 ...

The present work dealt with RAPD markers for genetic diversity comparison estimation in twenty three cotton varieties of Bt and non-Bt cotton cultivars belonging to two cultivated species of cotton in Andhra Pradesh state, India.Variations among twenty three different cotton varieties were analyzed with selected 40 RAPD primers using the polymerase chain reaction (PCR). All the primers produced...

Although manioc is well adapted to nutrient-poor Oxisols of Amazonia, ethnobotanical observations show that bitter manioc is also frequently cultivated in the highly fertile soils of the floodplains and Amazonian dark earths (ADE) along the middle Madeira River. Because different sets of varieties are grown in each soil type, and there are agronomic similarities between ADE and floodplain varie...
