The pharmacological activities in bioactive plant extracts play an increasing role in sustainable resources for valorization and biomedical applications. Bioactive phytochemicals, including natural compounds, secondary metabolites and their derivatives, have attracted significant attention for use in both medicinal products and cosmetic products. Our review highlights the pharmacological mode-of-action and current biomedical applications of key bioactive compounds applied as anti-inflammatory, bactericidal with antibiotics effects, and pain relief purposes in controlled clinical studies or preclinical studies. In this systematic review, the availability of bioactive compounds from several salt-tolerant plant species, mainly focusing on the three promising species Aster tripolium, Crithmum maritimum and Salicornia europaea, are summarized and discussed. All three of them have been widely used in natural folk medicines and are now in the focus for future nutraceutical and pharmacological applications. 相似文献

Lignocellulosic biomass is mainly composed of cellulose, hemicellulose, and lignin. Fuzzy logic, in turn, is a branch of many-valued logic based on the paradigm of inference under vagueness. This paper presents a methodology, based on computational intelligence, for modeling the kinetics of a complex reactional system. The design of a fuzzy interpolator to model cellulose hydrolysis is reported, within the perspective of applying kinetic models in bioreactor engineering. Experimental data for various types of lignocellulosic materials were used to develop the interpolator. New experimental data from the enzymatic hydrolysis of a synthetic substrate, on the other hand, were used to validate the methodology. The accuracy of the results indicates that this is a promising approach to extend the application of models fitted for specific situations to different cases, thus enhancing their generality. 相似文献

Nonlinear diffusion equations provide useful models for a number of interesting phenomena, such as diffusion processes in
porous media. We study here a family of nonlinear Fokker-Planck equations endowed both with a power-law nonlinear diffusion
term and a drift term with a time dependent force linear in the spatial variable. We show that these partial differential
equations exhibit exact time dependent particular solutions of the Tsallis maximum entropy (q-MaxEnt) form. These results constitute generalizations of previous ones recently discussed in the literature [C. Tsallis,
D.J. Bukman, Phys. Rev. E 54, R2197 (1996)], concerning q-MaxEnt solutions to nonlinear Fokker-Planck equations with linear, time independent drift forces. We also show that the present
formalism can be used to generate approximate q-MaxEnt solutions for nonlinear Fokker-Planck equations with time independent drift forces characterized by a general spatial
dependence.

We associate different types of full groups to Cantor minimal systems. We show how these various groups (as abstract groups)
are complete invariants for orbit equivalence, strong orbit equivalence and flip conjugacy, respectively. Furthermore, we
introduce a group homomorphism, the socalled mod map, from the normalizers of the various full groups to the automorphism
groups of the (ordered)K
0-groups, which are associated to the Cantor minimal systems. We show how this in turn is related to the automorphisms of the
associatedC
*-crossed products. Our results are analogues in the topological dynamical setting of results obtained by Dye, Connes-Krieger
and Hamachi-Osikawa in measurable dynamics.

One serious difficulty in modeling a fermentative process is the forecasting of the duration of the lag phase. The usual approach
to model biochemical reactors relies on first-principles, unstructured mathematical models. These models are not able to take
into account changes in the process response caused by different incubation times or by repeated fed batches. Toover come
this problem, we have proposed a hybrid neural network algorithm. Feedforward neural networks were used to estimate rates
of cell growth, substrate consumption, and product formation from on-line measurements during cephalosporin C production.
These rates were included in the mass balance equations to estimate key process variables: concentrations of cells, substrate,
and product. Data from fed-batch fermentation runs in a stirred aerated bioreactor employing the microorganism Cephalosporium acremonium ATCC 48272 were used. On-line measurements strongly related to the mass and activity of the cells used. They include carbon
dioxide and oxygen concentrations in the exhausted gas. Good results were obtained using this approach. 相似文献
