Genetic characterization of paternal lineages by Y-STR in three sample populations in Northeastern Brazil.

Genetic markers of the Y chromosome are powerful tools for investigating paternal ancestry and are widely used in population and forensic genetics. However, in order to obtain statistics with a higher degree of certainty using these markers, it is necessary to obtain haplotypic frequencies from a representative database, as well as knowing the diversity and structure of the population. The aim of this study was to investigate the genetic diversity of a sample of 1114 unrelated men from three states in the Northeast of Brazil: Paraíba, Pernambuco and Ceará, through the analysis of 23 Y-STRs and to contribute to the expansion of the Brazilian database on these markers.

Arachis mottle-associated virus, a new polerovirus infecting Pinto peanut.

A new polerovirus, named "arachis mottle-associated virus" (ArMoV), was identified by high-throughput sequencing in a Pinto peanut (Arachis pintoi) plant. The genome sequence was confirmed by Sanger sequencing and contains 5775 nucleotides and seven predicted open reading frames (ORFs), showing a typical polerovirus genome structure. All of the proteins encoded by ArMoV showed less than 90% amino acid sequence identity to those of other poleroviruses, the threshold to establish a new species in the genus.

Effect of different levels of whole corn germ on energy values and ileal digestibility in broilers.

This study evaluated the effects of broiler age (A) and levels of replacement (L) of control diet (CD) on the utilization of energy and nutrients of whole corn germ. 720 one-day-old broilers (b) were allocated at completely randomized design to six treatments and six replicates, in three assays: pre-starter (1-8 days, 10 b/cage), starter (15-22 days, 6 b/cage), and grower (28-35 days, 4 b/cage) phases. The treatments were: CD and four test diets (L): 100, 150, 200, 250, or 300 g kg-1 of the CD replaced by WCG levels.

Oral diseases are one of the biggest public health problems worldwide, caused by opportunistic pathogens such as and . (priprioca) is a plant conventionally used in traditional medicine in the Amazon region. However, little is known about the possible dentistry-related uses of extracts from the rhizomes and solid waste generated by the extraction of essential oils from this vegetable.

Specific antibody production using recombinant proteins to elucidate seed transmission and nuclear localization of Coguvirus citrulli and Coguvirus henanense in radicles of watermelon crop.

Watermelon crinkle leaf-associated virus 1 (WCLaV-1) and WCLaV-2, both belonging to the genus Coguvirus (family Phenuiviridae), have been identified in watermelon plants in Brazil. To study tissue tropism and the potential for seed transmission of these viruses, we initially planned to produce specific antibodies. However, difficulties in isolating and propagating the virus in host plants hindered the purified virus preparations.

Disentangling the ecotoxicological selectivity of clove essential oil against aphids and non-target ladybeetles.

The plant-based biopesticides have been proposed as insect pest control tools that seem to be safer for the environment and human health when compared to synthetic conventional molecules. However, such assumptions are generally made without considering the absence of detrimental effects on sublethally-exposed non-target organisms or showing the physiological basis of the selective action of such botanical products. Thus, by using in silico-based and in vivo toxicological approaches, the present investigation aimed to disentangle the ecotoxicological selectivity of clove, Syzygium aromaticum, essential oil against the aphid Rhopalosiphum maidis and the non-target ladybeetle, Coleomegilla maculata.

Third Molar Displacement into Submandibular Space.

There are various accidents and complications that may occur during extraction of dental elements. The displacement of dental elements to other facial spaces is one kind of the possible complications, and there may be significant physical and psychological results for the patient. The treatment for this kind of occurrence may vary from a conservative technique to surgical procedure, what will depend on clinical characteristics, symptoms, the location of the dental element, and its relation to adjacent structures.

Isolation and characterization of trypanosomatids, including Crithidia mellificae, in bats from the Atlantic Forest of Rio de Janeiro, Brazil.

We studied infection by Trypanosomatidae in bats captured in two areas with different degradation levels in the Atlantic Forest of Rio de Janeiro state: Reserva Ecológica de Guapiaçu (REGUA) and Estação Fiocruz Mata Atlântica (EFMA). Furthermore, we evaluated whether the diversity of trypanosomatids changes according to bat diversity and the different levels of preservation in the region. The results showed no influence of the level of preservation on bat species richness (15 and 14 species, respectively), with similar chiropterofauna and higher abundance of two common fruit-eating bat species in the tropics: Carollia perspicillata and Artibeus lituratus.

Improved tribo-mechanical behavior of CaP-containing TiO2 layers produced on titanium by shot blasting and micro-arc oxidation.

The combination of shot blasting (SB) and micro-arc oxidation (or anodic oxidation--AO) in titanium surfaces was shown to provide enhanced conditions for cell differentiation and osseointegration than those provided by SB or AO alone. This study associated both methods aiming to attain titania layers on Ti with adequate tribo-mechanical features for bone implants. SB was performed using alumina particles, and titania layers were grown by AO using a CaP-based electrolyte.

Fatal esophageal fibrosarcoma associated to parasitism by spirurid nematode Spirocerca lupi in a dog: a case report.

A 7-years-old intact female mixed breed dog was referred to the private veterinary clinic because of history of intense food regurgitation. The plain X-ray examination and the contrast-enhanced X-ray using barium sulfate revealed the presence of a radio-opaque mass in the final third of the esophagus. Stool samples were collected and the coproparasitological test was done, which showed thick-shelled eggs from Spirocerca lupi.

Phenolic constituents and antioxidant capacity of four underutilized fruits from the Amazon region.

The Amazon region comprises a plethora of fruit-bearing species of which a large number are still agriculturally unimportant. Because fruit consumption has been attributed to an enhanced physical well-being, interest in the knowledge of the chemical composition of underexplored exotic fruits has increased during recent years. This paper provides a comprehensive identification of the polyphenolic constituents of four underutilized fruits from the Amazon region by HPLC/DAD-ESI-MS(n).

Biapigenin modulates the activity of the adenine nucleotide translocator in isolated rat brain mitochondria.

In this study, we investigated the effects of biapigenin, a biflavone present in the extracts of Hypericum perforatum, in rat brain mitochondrial bioenergetics and calcium homeostasis. We found that biapigenin significantly decreased adenosine diphosphate (ADP)-induced membrane depolarization and increased repolarization (by 68 and 37%, respectively). These effects were blocked by atractyloside and bongkrekic acid, but not oligomycin.

Neuroprotective effect of H. perforatum extracts on beta-amyloid-induced neurotoxicity.

In the present study we assessed the neuroprotective role of a Hypericum perforatum ethanolic extract and obtained fractions in amyloid-beta peptide (Abeta)((25-35))-induced cell death in rat cultured hippocampal neurons. Lipid peroxidation was used as a marker of oxidative stress by following the formation of TBARS in rat cortical synaptosomes, after incubation with ascorbate/Fe2+, alone or in the presence of EC97 effective concentrations of H. perforatum fractions.
