Background Streptomyces sp. DPUA 1576 from Amazon lichens was studied to protease and fibrinolytic production. A 2² factorial experimental design was applied to optimize its protease enzyme production using two independent variables, namely soybean flour and glucose concentrations. Results The optimal c...
La diabetes es un trastorno metabólico que se ha incrementado en Latinoamérica y Venezuela en la última década. Ejerce una influencia considerable en la morbimortalidad de las enfermedades cardiovasculares debido al desequilibrio hidrocarbon ado y a los pacientes fuera de los objetivos de la Asociaci...
OBJECTIVE: to analyze the total Premature Infant Pain Profile scores of premature infants undergoing arterial puncture during music and 25% glucose interventions, and to assess their association with neonatal and therapeutic variables. METHOD: a randomized clinical trial with 80 premature infants; 24 in ...
Background Optimization of nutrient feeding was developed to improve the growth of Bacillus subtilis in fed batch fermentation to increase the production of jiean-peptide (JAA). A central composite design (CCD) was used to obtain a model describing the relationship between glucose, total nitrogen, and th...
BACKGROUND: The Hawthorn (Crateagus sp.) mostly occurs around the temperate region of the world with a high number of species, producing a fruit with numerous beneficial effects for human health. The aim of the study was to determine organic acid and sugar contents in the fruit of a number of hawthorn sp...

Background: L-glutamic acid, the principal excitatory neurotransmitter in the brain and an important intermediate in metabolism acts as a precursor of γ-amino butyric acid (GABA). In the present study, culture condition for enhanced glutamic acid production by Lactobacillus plantarum MNZ was optimiz...

Activation of β2 adrenergic receptors by catecholamine or catecholamine-mimetic substances may enhance insulin secretion. We herein investigated KCl- and nutrient-stimulated insulin secretion in pancreatic islets isolated from β2 knockout (β2KO) mice. β2KO mice showed reduced body weight, fasting hyp...
This study evaluated the biochemical changes associated to successive captures of Salminus brasiliensis reared at different stocking densities. The experiment was conducted in tanks with a capacity of 1,000 L, connected to a recirculating system with temperature control and continuous aeration. Fish were...
