Enzymatic activity of bone markers on Lithobates catesbeianus (Shaw, 1802) growth during the ossification process

Braz. j. biol; 84 (), 2024
Abstract In order to better understand the ossification processes in anurans our study was carried out on tadpoles and adults of Lithobates catesbeianus. In this sense, we characterized the kinetic properties of alkaline phosphatase with p-nitrophenylphosphatase (pNPP) and pyrophosphate (PPi) and evaluat...

The Influence of Morphological Characteristics on the Ball Throwing Velocity in the Professional Handball Players

Int. j. morphol; 41 (6), 2023
SUMMARY: The aim of this study was to determine influence of upper limbs on the ball throwing velocity. A total of 10 professional handball players (25.74±4.84 years) participated in this study. All of them were playing in the top Montenegrin professional handball league. The results obtained in this st...

Analysis of drying kinetic of brewer ́s spent grains: effect of the temperature on the physical properties and the content of bioactive compounds

Vitae (Medellín); 30 (2), 2023
Background: Brewer ́s spent grain (BSG) is a biomass by-product generated in large volumes during industrial beer production. BSG has become a growing environmental problem, as most breweries discard it inappropriately, negatively impacting the environment. Alternatives for the exploitation ...

Fabrication of 1,4-alpha-D-glucan glucanohydrolase holding Gel-Scaffolds using Agar-Agar, a natural polysaccharide and Polyacrylamide, a synthetic organic polymer for continuous liquefaction of starch

Biosci. j. (Online); 39 (), 2023
1,4-alpha-D-glucan glucanohydrolase is among the most widely used commercial hydrolytic enzymes acting randomly on the glycosidic linkages of starch resulting in its saccharification and liquefaction. Its applicability in different industries can be improved by enhancing its stability and reusability. Th...

Análise cinética e cinemática da saída de bloco em natação de atletas deficientes visuais

Objetivos: investigar e correlacionar a cinética e cinemática da saída de bloco em natação de atletas deficientes visuais e normovisuais. Métodos: foram comparados parâmetros de desempenho entre os nadadores de ambos os sexos. A amostra contou com 16 nadadores, sendo 4 cegos, 2 baixa visão e 10 n...

Thin-layer drying characteristics, modeling and quality attributes of tomato slices dried with infrared radiation heating

Biosci. j. (Online); 38 (), 2022
An Infrared dryer was used to examine the drying of tomato slices. In this investigation, the influence of infrared radiation (IR) on the rate of drying, physical quality, energy combustion of tomato was estimated at three different levels of intensity at 0.15, 0.20, and 0.35 W/cm² under different air f...

Blood glucose kinetics during concentric and eccentric muscle contractions

Biosci. j. (Online); 38 (), 2022
Studies comparing the two classes of stimuli (concentric and eccentric) have shown differences in the improvement of cardiovascular, metabolic, and muscle strength gain. This is an experimental, quantitative, and prospective study that aimed to verify the effect of eccentric exercise on glycolytic consum...

Studies on the enzymatic specificity of diguanylate cyclases domains and the production of new second messengers

In the first chapter, studies on substrate recognition and enzymatic activity of GGDEF domains are presented. Many proteins containing GGDEF domains are diguanylate cyclases (DGCs, EC 2.7.7.65), enzymes that catalyze the conversion of 2 GTP molecules into the second messenger c-di-GMP in prokaryotes. Thi...

Formulation of stomach-specific floating microparticles of nizatidine and their radiographic evaluation

Nizatidine is an anti-secretogogue and a gastroprotective drug with a half-life of 1-2 h and is well absorbed in the stomach. This study aimed to optimize the process and develop floating microparticles of nizatidine that are based on low methoxyl pectin. Oil-in-oil dispersion method and Taguchi orthogon...

The influence of subtalar axis orientation on the foot posture of older adults in a closed kinetic chain

Objectives: This study compared the influence of subtalar axis position on foot behavior in a closed kinetic chain in older and younger adults. Methods: The sample included 50 older adults and a control group of 50 younger adults. The variables were initially analyzed for both feet together, and were lat...
