Authors: D.N. Santos, J.L. Ferreira, M. Pasqual, A.L. Generoso3, T.A. Setotaw, G.M.A. Can�§ado and W.A. Vendrame
Jatropha (Jatropha curcas L.) has potential as an oilseed crop that requires the development of technology for its exploitation. The objective of this study was to assess the population structure and the genetic diversity in jatropha accessions at a global level using simple sequence repeat (SSR) molecular markers. Jatropha accessions (N = 109) from 10 co.. Read More»

Experimental strategies in carrying out VCU for tobacco crop I: plot design and size
Authors: F.H.R.B. Toledo, M.A.P. Ramalho, C.E. Pulcinelli and A.T. Bruzi
We aimed to establish standards for tobacco Valor de Cultivo e Uso (VCU) in Brazil. We obtained information regarding the size and design of plots of two varietal groups of tobacco (Virginia and Burley). Ten inbred lines of each varietal group were evaluated in a randomized complete block design with four replications. The plot contained 42 plants with si.. Read More»

Assessment of genetic divergence among coffee genotypes by Ward-MLM procedure in association with mixed models
Authors: W.P. Rodrigues, H.D. Vieira, P.E. Teodoro F.L. Partelli and D.H.S.G. Barbosa
Mixed linear models have been used for the analysis of the genetic diversity and provided further accurate results in crops such as eucalyptus, castor, and sugarcane. However, to date, research that combined this analysis with Ward-MLM procedure has not been reported. Therefore, the aim of the present study was to identify div.. Read More»

Drosha, DGCR8, and Dicer mRNAs are down-regulated in human cells infected with dengue virus 4, and play a role in viral pathogenesis
Authors: S.M.M. Casseb, D.B. Simith, K.F.L. Melo, M.H. Mendon�§a, A.C.M. Santos, V.L. Carvalho, A.C.R. Cruz and P.F.C. Vasconcelos
Dengue virus (DENV) and its four serotypes (DENV1-4) belong to the Flavivirus genus of the Flaviviridae family. DENV infection is a life-threatening disease, which results in up to 20,000 deaths each year. Viruses have been shown to encode trans-regulatory small RNAs, or microRNAs (miRNAs), which bind to messenger RNA and nega.. Read More»

Mitochondrial dysfunction in resveratrol-induced apoptosis in QGY-7701 cells
Authors: J.P. Li, Q. Ma and C.M. Chen
This study aims to evaluate the cytotoxicity of resveratrol on QGY-7701 cells via a cell viability assay, and determine the cytological alterations and damages that result. Resveratrol was found to inhibit QGY-7701 cell growth and decrease their viability in a remarkably dose-dependent manner. Resveratrol exposure also induced an increase in Caspase-3 act.. Read More»

Expression profile of rice Hsp genes under anoxic stress
Authors: L.M. Mertz-Henning, C. Pegoraro, L.C. Maia, E. Venske, C.V. Rombaldi and A. Costa de Oliveira
Although flooding is one of the most important environmental stresses worldwide, not all plant species are intolerant to its effects. Species from semi-aquatic environments, such as rice, have the capacity to cope with flooding stress. Heat-shock proteins (Hsps) are thought to contribute to cellular homeostasis under both opti..

Phylogenetic relationships among Octopodidae species in coastal waters of China inferred from two mitochondrial DNA gene sequences
Authors: Z.M. L�¼, W.T. Cui, L.Q. Liu, H.M. Li and C.W. Wu
Octopus in the family Octopodidae (Mollusca: Cephalopoda) has been generally recognized as a “catch-all” genus. The monophyly of octopus species in China’s coastal waters has not yet been studied. In this paper, we inferred the phylogeny of 11 octopus species (family Octopodidae) in China’s coastal waters using nucleotide sequences.. Read More»

Role of PPAR�± in down-regulating AGE-induced TGF-�² and MMP-9 expressions in chondrocytes
Authors: J. Wang, G. Wang and G.W. Sun
Peroxisome proliferator-activated receptor is closely associated with the pathogenesis of osteoarthritis. The level of exogenous advanced glycation end-products (AGEs) in articular cartilage is highly associated with the severity of osteoarthritic lesions. However, their interactions and role in promoting osteoarthritisprogres.. Read More»

Authors: P.E. Teodoro, F.E. Torres, A.D. Santos, A.M. Corr�ªa, M. Nascimento, L.M.A. Barroso4 and G. Ceccon
The aim of this study was to evaluate the suitability of statistics as experimental precision degree measures for trials with cowpea (Vigna unguiculata L. Walp.) genotypes. Cowpea genotype yields were evaluated in 29 trials conducted in Brazil between 2005 and 2012. The genotypes were evaluated with a randomized block design w.. Read More»
