Response surface methodology (RSM) is a widely used tool for modeling and optimization for food processes. The objective of this review is to evaluate recent findings on the use of RSM in the extraction of compounds from agri-food products. First, the steps for the application of RSM were briefly detailed. According to the analysis performed, RSM is suitable because it evaluates the effects of the independent variables and their interactions on the responses, which is ideal for the optimization of ...

The use of plastic polymers in food packaging causes serious environmental and health problems and as a result, natural biopolymers are being developed (NBPs). Although NBPs have several shortcomings as a packaging material, these can be overcome with the help of nanotechnology. In this context, this review will report on the main findings about the effect of the integration of metal nanoparticles (MNPs) on the characteristics of NBPs. A systematic review was carried out using PRISMA methodology to ...

ObjectivesThis study was focused on the role of indole acetic acid (IAA) in the defense against oxidative stress damage caused by drought in soybean plants and to elucidate whether heme oxygenase-1 (HO-1) and nitric oxide (NO) are involved in this mechanism. IAA is an auxin that participates in many plant processes including oxidative stress defense, but to the best of our knowledge no information is yet available about its possible action in drought stress.MethodsTo this end, soybean plants were treated ...

Mayonnaise is microbiologically stable, thus its shelf‐life is determined by the change in its sensory properties, mainly flavor changes due to oxidative rancidity of its main component, oil. The effect of storage temperature, fat content and type of package on the shelf‐life of a commercial mayonnaise was studied. Sensory descriptors with corresponding references are presented. The sensory descriptors which varied with storage time were: total aroma, and for flavor: egg, oily and oxidized. Rate ...

Plants are frequently subjected to different kinds of stress, such as salinity and, like other organisms, they have evolved strategies for preventing and repairing cellular damage caused by salt stress. Glycine max L. plants were subjected to different NaCl concentrations (0-200 mM) for 10 days. Treatments with 100 and 200 mM NaCl induced ion leakage and lipid peroxidation augmentation, loss in chlorophyll content, and accumulation of O(2) (*-) and H(2)O(2). However, 50 mM NaCl did not modify these parameters, ...

The objectives of this work were to develop sensory descriptors and references for the sensory analysis of the product and generate a sensory profile of 9 Argentine commercial samples from different brands. Eleven descriptors were developed for appearance, 8 for aroma and 11 for flavour. Aroma and flavour descriptors needed specific references for panel training. ...

COVID-19 is caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and has a case-fatality rate of 2–3%, with higher rates among elderly patients and patients with comorbidities. Radiologically, COVID-19 is characterised by multifocal ground-glass opacities, even for patients with mild disease. Clinically, patients with COVID-19 present respiratory symptoms, which are very similar to other respiratory virus infections. Our knowledge regarding the SARS-CoV-2 virus is still very ...

The selection of replacements using applications such as reproductive tract scores and antral follicle count may be useful to eliminate less fertile animals before breeding. Previously, we reported that heifers with increased numbers of follicles achieved puberty earlier than heifers with diminished numbers of follicles. We, therefore, hypothesized that heifers that achieved a reproductive tract score ≥4 earlier in the breeding season would have greater numbers of follicles than heifers that achieved ...

Transformed cells suffer several changes leading to the increase of protective mechanisms and show a metabolic profile in accordance with higher proliferative capacity. In these mechanisms, changes in mitochondrial activity cause a higher glycolytic metabolism in detriment of oxidative phosphorylation. In these changes, H+-ATPase regulation seems to be importantly involved. During the last years, polyphenols and specially the stilbene resveratrol and related members of its family have been studied ...

CYB5R3 encodes for NADH-dependent redox enzyme that contributes to metabolic homeostasis and stress protection; however, how it is involved in the neurological pathology of RHM remains unknown. Here, the role and transcriptional regulation of CYB5R3 was studied under nutritional and oxidative stress. Results:CYB5R3-deficient ...

In intensity modulated radiation therapy (IMRT), intensity maps are computed from prescribed doses to target volumes, adding dose restrictions to the surrounding tissues. Those intensity (fluence) maps are discretized into matrices of natural numbers and translated to sequences of multileaf collimator (MLC) leaf movements, which will finally deliver the computed x-ray intensities. A unidirectional leaf sequencing algorithm that controls the shape of the segments and reduces leaf motion time for step- ...
