Change in heritability estimates due to half-sib family selection in the maize variety Pahari
Authors: M. Noor, D. Shahwar, H. Rahman, H. Ullah, F. Ali, M. Iqbal, I.A. Shah and I. Ullah
This research was carried out at the Agriculture Research Farm, Khyber Pakhtunkhwa Agricultural University, Peshawar, and the Cereal Crops Research Institute, Pirsabak, Nowshera, during 2009 and 2010. Half-sib families (HS) derived from the maize variety Pahari in spring crop seasons 2009 and 2010 were developed at the Cereal Crops Research Institute. All.. Read More»

Whole-genome duplications contributed to the expansion of cytochrome b5 genes in Paramecium tetraurelia
Authors: K.J. Wu, D. Wang, J. Ding, S.H. Yang and X.H. Zhang
Cytochrome b5 (cyt b5) genes encode ubiquitous electron transport hemoproteins found in animals, plants, fungi, and purple bacteria. However, little is known about their evolutionary history in genomes so far. Here, we conducted an extensive genome-wide survey of cyt b5 genes in 20 representative model species and identified 310 of these genes. Both the a.. Read More»

G�?±q gene promoter polymorphisms and rheumatoid arthritis in the Han Chinese population are not associated
Authors: Y. Li, Y. Wang, Y. He, D. Wang, L. Deng, Y. Du and G. Shi
Mice that lose Gαq from their immune system can spontaneously develop inflammatory arthritis. Gαq expression in the peripheral blood lymphocytes of rheumatoid arthritis (RA) patients is significantly decreased in comparison to that in healthy individuals, and reduced Gαq expression is closely correlated with RA disease activity. These in.. Read More»

Cloning and polymorphism analysis of the 2-methyl-6-phytyl-1,4-benzoquinol methyltransferase gene (VTE3) in Arachis hypogaea, A. duranensis, and A. ipa�?«nsis
Authors: F.Z. Liu, A.Q. Guo and Y.S. Wan
One of the critical enzymes involved in vitamin E biosynthesis in plants is 2-methyl-6-phytyl-1,4-benzoquinol methyltransferase (MPBQ MT). The full-length VTE3 cDNA (designated rVTE3-1 and -2) encoding MPBQ MT and the full-length DNA of VTE3 (designated gVTE3-1 and -2) were isolated from cultivated peanuts (Arachis hypogaea). The full-length DNA of VTE3 (.. Read More»

Karyotype studies on populations of two Hypochaeris species (H. catharinensis and H. lutea), Asteraceae, endemics to southern Brazil
Authors: F.G. Fiorin, P.M. Ruas, M.A. Ortiz, E. Urtubey, N.I. Matzenbacher and C.F. Ruas
Hypochaeris is an excellent system for studying different modes of chromosome evolution in plants. We carried out a cytogenetic analysis on populations of 2 Hypochaeris species, comprising 10 populations of H. catharinensis and 5 of H. lutea, to assess possible changes on chromosome organization in this interesting genus. Conventional Feulgen staining and.. Read More»

Genetic variations in the Wnt signaling pathway affect lung function in asthma patients
Authors: S.-H. Wang, F. Xu1, H.-X. Dang and L. Yang
Identifying genetic determinants for lung function is important in providing insight into the pathophysiology of asthma. The Wnt signal pathway plays a role in lung development and in asthma pathogenesis. However, whether genetic polymorphisms of Wnt signal pathway are associated with lung function in asthma patients remain unclear. We genotyped 2 single .. Read More»

Comments on the article ��?Relative h-index to compare the scientific performance of researchers� by L.A.S. Dias
Authors: L. Egghe
The relative h-index, proposed by L.A.S. Dias, is not useful to compare the scientific performance of researchers. This is shown by examples. More adequate alternatives include the g-index and the R-index... Read More»

Effect of parasitism of Diatraea saccharalis (Lepidoptera: Crambidae) larvae by the wasp Cotesia flavipes (Hymenoptera: Braconidae) in defense reactions against abiotic agents: production and encapsulation reaction
Authors: C.C.C. Nunes and T.L. Silva
This study aimed to determine prophenoloxidase (proPO) activation and nitric oxide (NO) production in the hemolymph of Diatraea saccharalis larvae non-parasitized and parasitized by the wasp Cotesia flavipes and/or inoculated with abiotic agent (Sephadex beads), during parasitism/inoculation, and related to larval age; the ultrastructure of the capsule fo..
