Combining ability analysis provides useful information for the selection of parents, in breeding program cucumber at Can tho, VietNam, as well related to nature and extent gene activities involved. Cucumberimprovement involves strategies enhance yieldpotential quality cucumber. Targeting improvement new varieties plants, combining abilities genetic parameters 12 traits estimated from full diall...

The Tetrahymena group I ribozyme requires a hierarchical folding process to form its correct three-dimensional structure. Ribozyme activity depends on the catalytic core consisting of two domains, P4-P6 and P3-P7, connected by a triple-helical scaffold. The folding proceeds in the following order: (i) fast folding of the P4-P6 domain, (ii) slow folding of the P3-P7 domain, and (iii) structure r...

Cutaneous spinal sensory transmission appears to lack inhibitory control in the newborn spinal cord, but the properties of GABAergic and glycinergic synapses in the neonatal dorsal horn have not been characterized. Whole-cell patch-clamp recordings from rat superficial dorsal horn neurons in spinal cord slices at postnatal day 0 (P0) to P2, P6-P7, and P13-P14 revealed an age-dependent increase ...

A graph is H-free if it does not contain an induced subgraph isomorphic to H . We denote by Pk and Ck the path and the cycle on k vertices, respectively. In this paper, we prove that 4-COLORING is NP-complete for P7-free graphs, and that 5-COLORING is NP-complete for P6-free graphs. These two results improve all previous results on kcoloring Pt-free graphs, and almost complete the classificatio...

Developing a high-yielding and provitamin A-rich maize variety is one of the best approaches to reduce malnutrition increase production, especially in regions where staple food, such as, former Katanga Province Democratic Republic Congo. However, it requires good knowledge combining ability heterosis for grain yield A. Thus, evaluating yield, A content other agronomic traits eight lines, four t...

Two different responses to the therapy were observed in a group of patients receiving the protease inhibitor indinavir. In one, suppression of virus replication occurred and has persisted for 90 weeks (bDNA, < 500 human immunodeficiency virus type 1 [HIV-1] RNA copies/ml). In the second group, a rebound in virus levels in plasma followed the initial sharp decline observed at the start of therap...

We adopt the following rules: p1, p2, p3, p4, p5, p6, p, p7 denote points of E2 T and a, b, c, r, s denote real numbers. Next we state four propositions: (1) If sin](p1, p2, p3) = sin](p4, p5, p6) and cos](p1, p2, p3) = cos](p4, p5, p6), then ](p1, p2, p3) = ](p4, p5, p6). (2) sin](p1, p2, p3) = −sin](p3, p2, p1). (3) cos](p1, p2, p3) = cos](p3, p2, p1). (4) ](p1, p4, p2)+](p2, p4, p3) = ](p1, ...

BACKGROUND Recent reports have shown that there are developmental changes in the ventilatory response to hypercapnia in the rat. These are characterized by an initial large response to carbon dioxide immediately after birth followed by a decline with a trough at one week of age, followed by a return in sensitivity. A second abnormality is seen at postnatal day 5 (P5) rats in that they cannot ma...

BACKGROUND: Various treatment modalities are available to improve esthetics of fluorosed teeth based on its severity. AIM: The aim the study was evaluate clinical performance different minimal invasive protocols mild moderate teeth. METHODS AND MATERIALS: Before interventions, tooth color coordinates L, a and b were recorded for 160 by Vita Easyshade V. Participants randomly allocated in eight ...
