1. Epoetin alfa resistance in hemodialysis patients with chronic kidney disease: a longitudinal study
Anemia is an inevitable complication of hemodialysis, and the primary cause is erythropoietin deficiency. After diagnosis, treatment begins with an erythropoiesis-stimulating agent (ESA). However, some patients remain anemic even after receiving this medication. This study aimed to investigate the factors associated with resistance to recombinant human eryth

2. Physical and mechanical properties of particleboard bamboo waste bonded with urea formaldehyde and castor oil based adhesive
This study evaluated the physical and mechanical characteristics of particleboards made of bamboo waste from the species Dendrocalamus giganteus bonded with two different types of adhesives: urea-formaldehyde (UF) and a castor oil based adhesive (M). Thus, eight types of particleboards were produced in the proportions of 6%, 8%, 10% and 12% for each adhesiv

3. ÍNDICE RELATIVO DE CLOROFILA PARA O DIAGNÓSTICO DO ESTADO DE NITROGÊNIO EM HÍBRIDOS DE MILHO
Nitrogen (N) is the nutrient that contributes the most to increase productivity of corn hybrids. For this reason, the main objective of this study is to determine the relative chlorophyll index (RCI), in different leaves and phenological stages, aiming diagnosing N state in corn hybrids according to the N doses applied in coverage, correlating them with the

5. Ammonia detoxication efficacy in cattle adapted or not to dietary urea and afterwards undergone to different privation periods / Eficiência da desintoxicação de amônia em bovinos adaptados ou não com uréia dietética e submetidos a diferentes períodos de privação
This study was carried out to investigate the recommendation stated by Huber (1978) that there is a need to re-adapted cattle that were fed previously with dietary urea, but subsequently were deprived of this nutrient for more than 3 d. Twenty four steers fed a low crude protein ration, deprived of urea, were randomly distributed into 5 equal groups, and wer

6. Overproduction from a cellulase gene with a high guanosine-plus-cytosine content in Escherichia coli.
A recombinant exoglucanase was expressed in Escherichia coli to a level that exceeded 20% of total cellular protein. To obtain this level of overproduction, the exoglucanase gene coding sequence was fused to a synthetic ribosome-binding site, an initiating ATG, and placed under the control of the leftward promoter of bacteriophage lambda contained on the run
