1. The impact of COVID-19 in children and adolescents with obesity in Brazil
ABSTRACT Objective: The primary goal of the study was to evaluate weight gain in children and adolescents with obesity during the COVID-19 pandemic period, and compare it with the period before the pandemic. Subjects and methods: The sample comprised 68 children with obesity aged between 7 and 18 years, 30 (44.1%) boys and 38 (55.9%) girls, who were attend

2. Mycorrhization and grafting improve growth in the tomato and reduce the population of Nacobbus aberrans
RESUMO A inoculação com fungos micorrízicos e o uso de porta-enxertos tolerantes ou resistentes aos nematoides são duas estratégias que permitem o controle e a convivência das plantas com esse patógeno. Contudo, ambas as técnicas sempre foram testadas de forma isolada, sendo seus efeitos positivos menores, se comparados com a possibilidade de suas so

3. Isolation and characterization of mesenchymal progenitors derived from the bone marrow of goats native from northeastern Brazil
PURPOSE:To characterize bone marrow progenitors cells grown in vitro,using native goats from northeastern Brazil as animal model.METHODS:Ten northeastern Brazil native goats of both genders were used from the Piauí Federal University Agricultural Science Center's (UFPI) - Goat Farming Sector. Bone marrow aspirates where taken from the tibial ridge and seede

4. Análise populacional genética de Larus dominicanus através do uso de microssatélites / Population genetic analysis of Larus dominicanus using microsatellites
The changes in the coast that has been caused by human action has led to impacts on species associated with this environment. Larus dominicanus is a seabird species widely distributed throughout the Southern Hemisphere. The generalist feeding habits allow this species take advantage from human action, leading to population growth, which is also observed in o

5. Geographic distribution, population size and conservation of Mimus gilvus (Aves: Mimidae) in the State of Rio de Janeiro / Distribuição, tamanho populacional e conservação de Mimus gilvus (Aves: Mimidae) no Estado do Rio de Janeiro
A extensão da distribuição geográfica e a abundância local se combinam para determinar o tamanho populacional total das espécies. Entretanto, tais atributos são desconhecidos para a maioria das aves. Isso representa um problema para a conservação das espécies, baseada primariamente na manutenção do número e distribuição destas. A União Intern

6. Listeria monocytogenes em linguiças do tipo frescal vendidas a varejo no município de Salvador-BA e eficácia do bacteriófago P100 no controle da contaminação pelo patógeno.
The outbreaks of Food-borne Diseases are a reason of concern for the food industries and public health organs. Listeria monocytogenes is known as an important pathogen causing diseases transmitted by food and its importance has been growing since the 1980s. Although the number of disease cases per year is relatively low, the infection can be serious, with le

7. Isolation, identification and evaluation of Pochonia chlamydosporia for controlling Meloidogyne javanica and promoting growth in tomato plants / Isolamento, identificação e avaliação de Pochonia chlamydosporia no controle de Meloidogyne javanica e na promoção de crescimento de tomateiro
Twenty-nine isolates of Pochonia chlamydosporia were found in Meloidogyne infested-soils samples of vegetables crops from Viçosa (MG), Mariópolis (PR) and Venda Nova do Imigrante (ES). Among them, 65.52 % were identified as P. chlamydosporia var. chlamydosporia and 34.48 % as P. chlamydosporia var. catenulata. The potential of these isolates including four

8. Evidence of high inbreeding in a population of the endangered giant anteater, Myrmecophaga tridactyla (Myrmecophagidae), from Emas National Park, Brazil
We report the genetic structure, relatedness and mating structure of a population of the endangered giant anteater Myrmecophaga tridactyla Linnaeus, 1758 in the Emas National Park, Brazil, based on variability at five microsatellite loci. Additionally, we addressed the hypothesis that the M. tridactyla population studied has low levels of polymorphism and hi

9. Microbial Ecology of Activated Sludge: II. Bacteriophages, Bdellovibrio, Coliforms, and Other Organisms
A comparative estimation of the coliform population of raw sewage, activated sludge, and the effluent derived therefrom revealed that raw sewage had a preponderance of Escherichia coli (75%), as compared with 25 and 30%, respectively, in sludge and effluent. Nitrogen-free mannitol-sucrose enrichments of activated sludge resulted in the isolation of Azotobact

10. The history of effective population size and genetic diversity in the Yellowstone grizzly (Ursus arctos): Implications for conservation
Protein, mtDNA, and nuclear microsatellite DNA analyses have demonstrated that the Yellowstone grizzly bear has low levels of genetic variability compared with other Ursus arctos populations. Researchers have attributed this difference to inbreeding during a century of anthropogenic isolation and population size reduction. We test this hypothesis and assess

11. Isolation and genetic analysis of Chlamydomonas reinhardtii strains resistant to cadmium.
In Chlamydomonas reinhardtii, cadmium induces reduction of growth, reduction of chlorophyll content, and lethality. The toxicity was higher in a cell wall-deficient strain than in the wild type. By growing the cells on agar medium containing cadmium at concentrations inducing high lethality, stable resistant clones were isolated. The resistance was due to a

12. Loss of serum response element-binding activity and hyperphosphorylation of serum response factor during cellular aging.
Human diploid fibroblasts undergo a limited number of population doublings in vitro and are used widely as a model of cellular aging. Despite growing evidence that cellular aging occurs as a consequence of altered gene expression, little is known about the activity of transcription factors in aging cells. Here, we report a dramatic reduction in the ability o
