Formaldehyde (FA) is an environmental xenobiotic, which is genotoxic and carcinogenic to humans and animals; it induces DNA damage, mutations, and clastogenicity during critical cytogenetic events. FA-mediated oxidative stress is an important mechanism that has been associated with the induction of cytotoxic and genotoxic damage. Therefore, the objective .. Read More»

Rearing Africanized honey bee (Apis mellifera L.) brood under laboratory conditions
Authors: I.C. Silva, D. Message, C.D. Cruz, L.A.O. Campos and M.J. Sousa-Majer
We developed a method for rearing larvae of Africanized bees under laboratory conditions to determine the amount of diet needed during larval development to obtain a worker bee. We started with larvae 18-24 h old, which were transferred to polyethylene cell cups and fed for five days. We found that the amount of diet needed fo.. Read More»

Africanized honey bees (Apis mellifera) have low infestation levels of the mite Varroa destructor in different ecological regions in Mexico
Authors: C.A. Medina-Flores, E. Guzm�¡n-Novoa, M.M. Hamiduzzaman, C.F. Ar�©chiga-Flores and M.A. L�³pez-Carlos
Honey bee (Apis mellifera) colonies of African and European descent were compared for levels of Varroa destructor infestation in 3 different ecological regions in Mexico. The 300 colonies that were studied were located in subtropical, temperate sub-humid, and temperate dry climates. The morphotype and mitotyp.. Read More»

Adaptive protection against damage of preconditioning human umbilical cord-derived mesenchymal stem cells with hydrogen peroxide
Authors: D. Li, Y. Xu, C.Y. Gao and Y.P. Zhai
Adaptive protection against damage to human umbilical cord-derived mesenchymal stem cells (hUC-MSCs) was investigated by preconditioning with low-concentration hydrogen peroxide (H2O2) for a short-time period. Separation, culture, amplification, purification, and identification of immunophenotype and grow.. Read More»

Gene organization and characterization of the complete mitogenome of Hypsugo alaschanicus (Chiroptera: Vespertilionidae)
Authors: J.Y. Kim and Y.C. Park
We sequenced and characterized the complete mitogenome of Hypsugo alaschanicus (Vespertilionidae) to provide more data for comparative mitogenomics of the genus Hypsugo. The mitogenome of H. alaschanicus is a circular molecule of 17,300 bp, consisting of a control region and a typically conserved set of 37 vertebrate genes containing 13 protein-coding gen..

Spatial patterns in the brood combs of Nannotrigona testaceicornis (Hymenoptera: Meliponinae): male clusters
Authors: A. Eterovic, G.C.P. Cabral, A.A. Oliveira, V.L. Imperatriz-Fonseca and P.S. Santos-Filho
Genetic models of sex and caste determination in eusocial stingless bees suggest specific patterns of male, worker and gyne cell distribution in the brood comb. Conflict between queen and laying workers over male parentage and center-periphery gradients of conditions, such as food and temperature, could also contribute to non-.. Read More»

Diversity of plant growth-promoting bacteria associated with sugarcane
Authors: J.E.L. Antunes, M.C.C.P. Lyra, F.J. Ollero, A.D.S. Freitas, L.M.S. Oliveira, A.S.F. Ara�ºjo and M.V.B. Figueiredo
The sugarcane (Saccharum spp) presents economic importance, mainly for tropical regions, being an important Brazilian commodity. However, this crop is strongly dependent on fertilizers, mainly nitrogen (N). This study assessed the plant growth-promoting bacteria (PGPB) associated with sugarcane that could be used as a potentia.. Read More»

Arg188His polymorphism in the XRCC2 gene and the risk of ovarian cancer: a meta-analysis
Authors: M. Zhai, Y. Wang and M.F. Jiang
Numerous studies have evaluated the association between the Arg188His polymorphism of the X-ray repair cross-complementing group 2 (XRCC2) gene and ovarian cancer risk. However, the specific association is still controversial. This meta-analysis was therefore designed to clarify these controversies. Relevant case-control studies were enrolled in the meta-..

Unraveling the variability and genetic structure of barker frog Physalaemus cuvieri (Leiuperinae) populations from different regions of Brazil
Authors: M. Conte, C.P. Targueta, M.I. Zucchi, A.P. Souza and S.M. Recco-Pimentel
The barker frog Physalaemus cuvieri is widely distributed in South America and is found in all regions of Brazil. Significant intraspecific morphological variation in this species has been reported. To determine the genetic structure of the natural Brazilian populations of P. cuvieri, 10 different populations geographically se.. Read More»

Strategy for selection of soybean genotypes tolerant to drought during germination
Authors: S.A.G. Dantas, F.C.S. Silva, L.J. Silva and F.L. Silva
Water deficit is the main reason for instability in the context of soybean culture. The development of strategies for the selection of more tolerant genotypes is necessary. These strategies include the use of polyethylene glycol 6000 solutions (PEG-6000) for conducting the germination test under conditions of water restriction.. Read More»
