Genetic diversity of Bacillus sp producers of amylase isolated from the soil
The microorganisms are the best source of extracellular enzymes since they allow an economical technology with low-resource consumption compared to animals and plants. The amylases are among the most important enzymes being the genus Bacillus one of the most investigated due to its ability to produce this enzyme. The objective of this study was to isolate and analyz.. Read More»

Chemical signatures in the developmental stages of Protopolybia exigua
The chemical signature of social insects is very important for communication, and specific signs of each colony and its individuals are acquired throughout their development. This chemical signature can also be related to the composition of the materials employed during nest construction. Furthermore, the venom also contains important chemicals required for the main..

Random regression models using different functions to model milk flow in dairy cows
We analyzed 75,555 test-day milk flow records from 2175 primiparous Holstein cows that calved between 1997 and 2005. Milk flow was obtained by dividing the mean milk yield (kg) of the 3 daily milking by the total milking time (min) and was expressed as kg/min. Milk flow was grouped into 43 weekly classes. The analyses were performed using a single-trait Random Regre.. Read More»

Campomanesia adamantium extract induces DNA damage, apoptosis, and affects cyclophosphamide metabolism
Campomanesia adamantium (Cambess.) O. Berg. is originally from Brazil. Its leaves and fruits have medicinal properties such as anti-inflammatory, antidiarrheal and antiseptic properties. However, the mutagenic potential of this species has been reported in few studies. This study describes the mutagenic/antimutagenic, splenic phagocytic, and apoptotic activities of .. Read More»

Characterization and molecular epidemiology of extensively prevalent nosocomial isolates of drug-resistant Acinetobacter spp
Acinetobacter sp isolates deserve special attention once they have emerged globally in healthcare institutions because they display numerous intrinsic and acquired drug-resistance mechanisms. This study assessed the antibiotic susceptibility profile, the presenceof the genetic marker blaOXA-23, and the clonal relationship among 34 nosocomial isolates of Acinetobacter spp obtained at a hospital ..

Genetic parameters for milk production traits and breeding goals for Gir dairy cattle in Brazil
To implement an animal breeding program, it is important to define the production circumstances of the animals of interest to determine which traits of economic interest will be selected for the breeding goal. The present study defined breeding goals and proposed selection indices for milk production and quality traits of Gir dairy cattle. First, a bioeconomic model.. Read More»

Random regression models using different functions to model test-day milk yield of Brazilian Holstein cows
We analyzed 152,145 test-day records from 7317 first lactations of Holstein cows recorded from 1995 to 2003. Our objective was to model variations in test-day milk yield during the first lactation of Holstein cows by random regression model (RRM), using various functions in order to obtain adequate and parsimonious models for the estimation of genetic parameters. Te.. Read More»

Cuticular signature in the development of Polistes versicolor
Wasps belong to societies that are highly complex and diverse, especially considering social organization and parental care. They use chemicals in their daily communication, and act incisively in recognition of mates and non-nest mates, and can even identify individuals of different castes. In this study, cuticle composition was examined during the development of Po.. Read More»

Efficiency of circulant diallels via mixed models in the selection of papaya genotypes resistant to foliar fungal diseases
Diallel crossing methods provide information regarding the performance of genitors between themselves and their hybrid combinations. However, with a large number of parents, the number of hybrid combinations that can be obtained and evaluated become limited. One option regarding the number of parents involved is the adoption of circulant diallels. However, informati.. Read More»

�±-Thalassemia (3.7 kb deletion) in a population from the Brazilian Amazon region: Santar�©m, Par�¡ State
The ethnic composition of the Brazilian population favors high frequencies of the -α3.7 deletion, responsible for α-thalassemia, because this mutation is very common in African populations. In spite of its importance, this hemoglobinopathy has been poorly investigated in Brazil, especially at the molecular level. We investigated the prevalence of the -&a.. Read More»
