Oscillators and switches are important elements of regulation in biological systems. These are composed of coupling negative feedback loops, which cause oscillations when delayed, and positive feedback loops, which lead to memory formation. Here, we examine the behavior of a coupled feedback system, the Negative Autoregulated Frustrated bistability motif (NAF). This motif is a combination of tw...

The diversity and ecological function of microorganisms associated with Euphausia superba, still remain unknown. This study identified 75 microbial isolates from E. superba, that is 42 fungi and 33 bacteria including eight actinobacteria. And all the isolates showed NaF tolerance in conformity with the nature of the fluoride krill. The maximum concentration was 10%, 3% and 0.5% NaF for actinoba...

AIM This randomized, double blind, split mouth study was aimed to compare three dentin desensitizing treatment modalities. METHODS Two hundred sixty teeth of 25 patients; each having at least 2 hypersensitive teeth in each quadrant, were included. Teeth were randomized to 4 groups: Group A treated with 2% NaF solution, Group B received GLUMA®; an aqueous solution of Hydroxy-Ethyl-Methacrylate...

Sodium fluoride ([18F]NaF) is a PET radiopharmaceutical for vizualization of the skeletal system and microcalcification. In originally designed in-house method, [18F]NaF recovered in aqueous solution after cyclotron irradiation, sterilized by passage through 0.22 µm sterile filter dispensed under aseptic conditions. To ensure microbiological safety drugs produced conditions, validation procedur...

Não está claro em que medida o melhor nível de aptidão f ísica (NAF), dentro do universo militares atendam ao padrão desempenho ísico mínimo exigido pela instituição, é realmente uma vantagem tarefas operacionais. Objetivo: investigar os efeitos NAF sobre equilíbrio corporal e as respostas fisiológicas tarefa transporte carga 4km. O foi coletado (n=22) usando equipamento pessoal (22kg), antes a...

Abstract A large amount of spent pot lining (SPL) is produced by cryolite-alumina melting electrolysis process, and the fluoride content in leaching solution up to 6000 mg/L, which belongs hazardous waste. If SPL not handled effectively, it will cause great harm environment. Because NaF rich an important raw material for synthesis cryolite carbonation, this paper uses as extract NaF. On basis e...

Brain, liver, kidney and muscles demonstrate significant changes in essential trace element (Cu, Zn, Mn and Fe) level in adult female mice given 30, 60 and 120 ppm sodium fluoride (NaF) in drinking water. These changes involve excess removal or accumulation of these trace elements in respective tissues. Changes observed were dose dependent and significant at 120 ppm NaF concentration in drinkin...

the effects of hydroalcoholic extract (he) of curculigo orchioides gaertn. rhizome (hypoxidaceae) and its alkaloidal and non-alkaloidal fractions (af) and (naf) were evaluated in carrageenan-induced paw edema experimental models of inflammation. the oral administration of he, their af and naf fractions were used at doses of 100, 300 and 500 mg/kg. the effect produced by the he, af and naf fract...

Gross cystic disease fluid protein 15 (GCDFP-15) is universally present in the apocrine metaplastic epithelium of cystic breast disease and breast cancer, but it is rarely found in normal breast epithelium. Therefore GCDFP-15 detected in nipple aspirates of breast fluid (NAF) could serve as a biochemical marker of the presence and possibly extent of apocrine metaplasia within the breast. GCDFP-...
