Self-assembly study of type I collagen extracted from male Wistar Hannover rat tail tendons
(BioMed Central Ltd, 2020-11-23)
Background: Collagen, the most abundant protein in the animal kingdom, represents a promising biomaterial for
regenerative medicine applications due to its structural diversity and self-assembling complexity. Despite ...
Biosensors for the Detection of Bacterial and Viral Clinical Pathogens
(MDPI AG, 2020-12-04)
Biosensors are measurement devices that can sense several biomolecules, and are widely
used for the detection of relevant clinical pathogens such as bacteria and viruses, showing outstanding
results. Because of the latent ...
Fungal biosynthesis of lignin-modifying enzymes from pulp wash and Luffa cylindrica for azo dye RB5 biodecolorization using modeling by response surface methodology and artificial neural network
(Elsevier, 2020-06-04)
This study demonstrates the evaluation between the artificial neural network technique coupled to the genetic
algorithm (ANN-GA) and the response surface methodology (RSM) for prediction of Reactive Black 5 (RB5)
decolorization ...

Evaluating watershed health in Costa Rican national parks and protected areas
(Springer Science and Business Media Deutschland GmbH, 2020-08-11)
Although the biodiversity of Costa Rican national parks, forests, and wetlands has been extensively surveyed, there has not
been a watershed assessment that refects their baseline water quality. Undoubtedly, the infux of ...
Headwaters drive streamflow and lowland tracer export in a large-scale humid tropical catchment
(John Wiley and Sons Ltd, 2020)
Headwaters are generally assumed to contribute the majority of water to downstream users, but
how much water, of what quality and where it is generated are rarely known in the humid tropics.
Here, using monthly monitoring ...
Green Synthesis of Gold and Silver Nanoparticles from Plant Extracts and Their Possible Applications as Antimicrobial Agents in the Agricultural Area
(MDPI AG, 2020-09-07)
Currently, metal nanoparticles have varied uses for different medical, pharmaceutical, and
agricultural applications. Nanobiotechnology, combined with green chemistry, has great potential
for the development of novel and ...
Enhancing the tolerance of Clostridium saccharoperbutylacetonicum to ligno‐ cellulosic-biomass-derived inhibitors for efficient biobutanol production by overexpressing efflux pumps genes from Pseudomonas putida
(Elsevier Ltd, 2020)
Furan aldehydes and phenolic compounds generated during biomass pretreatment can
inhibit fermentation for biofuel production. Efflux pumps actively transport small molecules out
of cells, thus sustaining normal microbial ...
Residual nitrite in processed meat products in Costa Rica: Method validation, long-term survey and intake estimations
(Elsevier Ltd, 2021-05-12)
Ingestion of high amounts of nitrite due processed meat consumption could produce negative effects in human health. Here, we investigate long-term residual sodium nitrite content in processed meat products in Costa Rica ...
New advances in the method validation, extraction methods and measurement uncertainty for the determination of water-soluble hexavalent chromium in hydraulic cement
(Elsevier Ltd, 2021-04-20)
The quantification of Cr (VI) in the cement matrix is highly important, given the possibility of suffering illnesses including dermatitis, induced nasal carcinoma, and DNA damage produced by inhalation of and/or direct ...
