Isolation and proteomic characterization of tropomyosin extracted from edible insect protein.

Edible insects are considered promising sustainable protein sources. Thermal treatments and proteolysis are commonly used to improve their safety and quality. However, their allergenicity remains mostly unexplored.

Protective role of lactic acid bacteria and yeasts as dietary carcinogen-binding agents - a review.

The importance of food contaminants in the link between diet and cancer has been widely demonstrated. Therefore, different physical and chemical strategies for the control of human exposure to such dietary carcinogens has been explored; however, most of these strategies are complex, costly, and have low efficiency which limited their applications. Hence, microbiological methods have been receiving more attention.

In Silico Prediction and In Vitro Assessment of Multifunctional Properties of Postbiotics Obtained From Two Probiotic Bacteria.

In this study, a global metabolite profile using Raman spectroscopy analysis was obtained in order to predict, by an in silico prediction of activity spectra for substance approach, the bioactivities of the intracellular content (IC) and cell wall (CW) fractions obtained from Lactobacillus casei CRL 431 and Bacillus coagulans GBI-30 strains. Additionally, multifunctional in vitro bioactivity of IC and CW fractions was also assessed. The metabolite profile revealed a variety of compounds (fatty acids, amino acids, coenzyme, protein, amino sugars), with significant probable activities (Pa > 0.

Functional properties of tropical banded cricket (Gryllodes sigillatus) protein hydrolysates.

Recently, the benefits of entomophagy have been widely discussed. Due to western cultures' reluctance, entomophagy practices are leaning more towards incorporating insects into food products. In this study, whole crickets (Gryllodes sigillatus) were hydrolyzed with alcalase at 0.

Vegetation dynamics and rainfall sensitivity of the Amazon.

We show that the vegetation canopy of the Amazon rainforest is highly sensitive to changes in precipitation patterns and that reduction in rainfall since 2000 has diminished vegetation greenness across large parts of Amazonia. Large-scale directional declines in vegetation greenness may indicate decreases in carbon uptake and substantial changes in the energy balance of the Amazon. We use improved estimates of surface reflectance from satellite data to show a close link between reductions in annual precipitation, El Niño southern oscillation events, and photosynthetic activity across tropical and subtropical Amazonia.

Tracking plant physiological properties from multi-angular tower-based remote sensing.

Imaging spectroscopy is a powerful technique for monitoring the biochemical constituents of vegetation and is critical for understanding the fluxes of carbon and water between the land surface and the atmosphere. However, spectral observations are subject to the sun-observer geometry and canopy structure which impose confounding effects on spectral estimates of leaf pigments. For instance, the sun-observer geometry influences the spectral brightness measured by the sensor.

Modeling the Exchanges of Energy, Water, and Carbon Between Continents and the Atmosphere.

Atmospheric general circulation models used for climate simulation and weather forecasting require the fluxes of radiation, heat, water vapor, and momentum across the land-atmosphere interface to be specified. These fluxes are calculated by submodels called land surface parameterizations. Over the last 20 years, these parameterizations have evolved from simple, unrealistic schemes into credible representations of the global soil-vegetation-atmosphere transfer system as advances in plant physiological and hydrological research, advances in satellite data interpretation, and the results of large-scale field experiments have been exploited.

Global crop forecasting.

Many foreign countries are as dependent on imports of food as the United States is on imports of oil. As the world's largest exporter of food, the United States needs reliable information on fluctuating foreign crop production. But available information is often inadequate and at best untimely.

HEMOGLOBIN AND OXYGEN: AFFINITIES IN SEVEN SPECIES OF SCIURIDAE.

Studies of the respiratory function of the bloods of seven species of squirrels suggest that, in the evolution and adaptive radiation of this group, the oxygen affinity of hemoglobin has changed in a manner to better adapt the various species to different ways of life and different habitats. These changes are shown by the relative positions of the oxygen-dissociation curves of bloods of several species having dissimilar habits and environments.
