The intracellular transfer of information (biological activation/inhibition) through a signal pathway. In each signal transduction system, an activation/inhibition signal from a biologically active molecule (hormone, neurotransmitter) is mediated via the coupling of a receptor/enzyme to a second messenger system or to an ion channel. Signal transduction plays an important role in activating cellular functions, cell differentiation, and cell proliferation. Examples of signal transduction systems are the GAMMA-AMINOBUTYRIC ACID-postsynaptic receptor-calcium ion channel system, the receptor-mediated T-cell activation pathway, and the receptor-mediated activation of phospholipases. Those coupled to membrane depolarization or intracellular release of calcium include the receptor-mediated activation of cytotoxic functions in granulocytes and the synaptic potentiation of protein kinase activation. Some signal transduction pathways may be part of larger signal transduction pathways; for example, protein kinase activation is part of the platelet activation signal pathway.

The molluscicidal activity of the latex of Euphorbia splendens var. hislopii on Melanoides tuberculata (Thiaridae), a snail associated with habitats of Biomphalaria glabrata (Planorbidae). (1/15)

The use of the latex of Euphorbia splendens var. hislopii was considered as an effective control method for Biomphalaria glabrata in Sumidouro, Rio de Janeiro. However, the appearance and expansion of the snail Melanoides tuberculata since August 1997, with the concomitant reduction of the population of B. glabrata suggest that competitive exclusion might be taking place. Depending on the susceptibility of the thiarid to the E. splendens toxin, the natural control that is occurring could be interrupted by the employment of the latex if the planorbid were less susceptible to the toxin. The aim of this study is to investigate the molluscicidal activity of the latex on M. tuberculata. We used 420 M. tuberculata, from Sumidouro. Fourteen different latex concentrations were tested using World Health Organization general methodology. Probit analysis was used for LD90 and LD50 determination. The LD50 was 3.57 mg/l and LD90 was 6.22 mg/l. At the highest concentration (10 mg/l) there was no survival. No significant differences among replicas (chi2 = 8.31; gl = 13; p > 0.05) were found. The LD90 dose for M. tuberculata was 13.8 times greater than that for B. glabrata, so that the molluscicide in the presence of the thiarid may have a synergic effect on reduction of Biomphalaria populations.  (+info)

Coevolutionary networks: a novel approach to understanding the relationships of humans with the infectious agents. (2/15)

Human organism is interpenetrated by the world of microorganisms, from the conception until the death. This interpenetration involves different levels of interactions between the partners including trophic exchanges, bi-directional cell signaling and gene activation, besides genetic and epigenetic phenomena, and tends towards mutual adaptation and coevolution. Since these processes are critical for the survival of individuals and species, they rely on the existence of a complex organization of adaptive systems aiming at two apparently conflicting purposes: the maintenance of the internal coherence of each partner, and a mutually advantageous coexistence and progressive adaptation between them. Humans possess three adaptive systems: the nervous, the endocrine and the immune system, each internally organized into subsystems functionally connected by intraconnections, to maintain the internal coherence of the system. The three adaptive systems aim at the maintenance of the internal coherence of the organism and are functionally linked by interconnections, in such way that what happens to one is immediately sensed by the others. The different communities of infectious agents that live within the organism are also organized into functional networks. The members of each community are linked by intraconnections, represented by the mutual trophic, metabolic and other influences, while the different infectious communities affect each other through interconnections. Furthermore, by means of its adaptive systems, the organism influences and is influenced by the microbial communities through the existence of transconnections. It is proposed that these highly complex and dynamic networks, involving gene exchange and epigenetic phenomena, represent major coevolutionary forces for humans and microorganisms.  (+info)

Exploratory research on bioactive natural products with a focus on biological phenomena. (8/15)

The discovery of new basic compounds holds the key for advancing material sciences. We have focused on the identification and characterization of natural key compounds that control biologically and physiologically intriguing phenomena. The discovery of new bioactive molecules, facilitated by a deeper understanding of nature, should advance our knowledge of biological processes and lead to new strategies to treat disease. The structure and function of natural compounds are sometimes unexpectedly original. Based on our past experience and results, we have carried out research to find new directions for compound exploration by directly learning from dynamic biological phenomena in the field, and have succeeded in creating a new research field in biological molecular sciences.  (+info)

Regardless of the optimization method used, model parameter optimization requires a measure for the goodness of model neuron or network activity, i.e. for how well the model produces the desired electrical activity pattern. As an alternative to maximizing the goodness of a model, parameter optimization methods can also minimize the difference between the models activity and the biological target activity as measured by a distance or error function. Because both strategies are in use, this article does not distinguish between maximizing a goodness measure or minimizing an error measure and uses the two optimization strategies interchangeably. The choice of goodness or error measure depends on the purpose of the model neuron or network and can have significant influence on the results and success of model parameter optimization. Examples of goodness or error measures are: ...

This paper also finds the optimal phase number for pattern encoding, and the optimal radial length ...
Abstract: Recent years have witnessed extensive research activity in modeling biological phenomena as well as in developing intervention strategies for such phenomena. S-systems, which offer a good compromise between accuracy and mathematical flexibility, are a promising framework for modeling the dynamical behavior of biological phenomena. In this paper, two different intervention strategies, namely direct and indirect, are proposed for the S-system model. In the indirect approach, the prespecified desired values for the target variables are used to compute the reference values for the control inputs, and two control algorithms, namely simple sampled-data control and model predictive control (MPC), are developed for transferring the control variables from their initial values to the computed reference ones. In the direct approach, a MPC algorithm is developed that directly guides the target variables to their desired values. The proposed intervention strategies are applied to the ...
EONS modeling platform is a resourceful learning and research tool to study the mechanisms underlying the non-linear dynamics of synaptic transmission with the aid of mathematical models. Mathematical modeling of information processing in CNS pathways, in particular modeling of molecular events and synaptic dynamics, have not been extensively developed owing to the complex computations involved in integrating a multitude of parameters. In this paper, we discuss the development of a strategy to adapt the EONS synaptic modeling platform to a multi-node environment using a parallel computational framework to compute data intensive long simulations in a shorter time frame. We describe how this strategy can be applied to (i) determine the optimal values of the numerous parameters required for fitting experimental data, (ii) determine the impact of all parameters on various aspects of synaptic transmission (under normal conditions or conditions mimicking pathological conditions) and (iii) study the ...
A sequence of measured quantities is determined for a chemical reactor and a data generator generates a curve in normal coordinates from a respective predetermined normal form that describes a type of critical state. Each normal form is imaged onto the sequence of measured quantities by neural networks whereby a respective neural network is allocated to a data generator. The imaging is optimized by applying parameter optimization methods. The neural network that converges best through use of parameter optimization method describes the critical state that lies closest to the actual state of the chemical reactor.
This article investigates the ability of using plasma machining for cutting simultaneously two parallel thin layers at different gap distances. The main aim of this work is to identify whether this technology if mechanized can be more appropriate than using a circular saw to process a three-dimensional structure material such as double layers, box sections or rails. This research is aimed at those working in the automotive industry and converting vehicles. Test models were built for the experiments using 0.7 mm thick steel sheets DCO1 grade, similar material used for some underbody vehicle chassis parts. Serie of cuts were carried out first to analyze the ability of the plasma to perform a simultaneous cutting in two separate sheets with an air gap, followed by tests to minimize the deformation and heat affected zones on the top sheets adopting Taguchi methodology. Parameters analyzed included cutting speed, intensity, pressure, and gap distance between the two sheets. The specimens collected ...

In this paper a new genetic algorithm called the Breeder Genetic Algorithm (BGA) is introduced. The BGA is based on artificial selection similar to that used by human breeders. A predictive model for the BGA is presented that is derived from quantitative genetics. The model is used to predict the behavior of the BGA for simple test functions. Different mutation schemes are compared by computing the expected progress to the solution. The numerical performance of the BGA is demonstrated on a test suite of multimodal functions. The number of function evaluations needed to locate the optimum scales only as n ln(n) where n is the number of parameters. Results up to n = 1000 are reported.. ...

Fit biologically meaningful distribution functions to time-sequence data (phenology), estimate parameters to draw the cumulative distribution function and probability density function and calculate standard statistical moments and percentiles.
The work presented has highlighted the many disadvantages of parameter optimisation. Whilst significant improvements in the r.m.s.e were achieved in some areas, this was only after extensive testing and regeneration of the same model. The large number of strategy parameters used in OrthoMAX means that to test every parameter combination would be an enormous undertaking and clearly impracticable in normal circumstances. The data and results from the study prove the extreme variability of the software in certain areas, and the importance and criticality of the strategy parameters. Whilst the parameters have proved to have a significant effect in certain areas, the data has shown that manipulation of the parameters has little if any effect in areas well suited to the matching algorithm. Improvements in the accuracy of these areas are likely to be marginal through manipulation of the strategy parameters. The tests in this study were all carried out on data with checkpoint information. If this data ...
Role: lead data analyst. Carnegie Learning, Inc. has accumulated a large body of data on student learning in Cognitive Tutor Algebra® in the order of hundreds of schools, tens of thousands of students, and tens of millions of student problem-solving steps. This project is focusing on harnessing the Big Data to set up a close the loop workflow for iterative improvement of the Cognitive Tutor®. The improvement is driven by using machine learning to tune the parameters of the Bayesian cognitive model that tracks students progress and controls problem selection.. First results (Yudelson, et al., 2014a) show that only a subset of the Big Data - the Better Data - needs to be utilized to drive the optimization. Preliminary investigation of the Bayesian model parameter optimization effects for college-level math courses shows that students could save up to 37% of their time spent in Cognitive Tutor ® (in preparation).. ...
Despite recent advances in the field of image-guided interventions (IGI), the bottleneck for Angiography/X-ray guided procedures in particular is accurate and robust 2D-3D image alignment. The conventional, straight-forward parameter optimisation approach is known to be ill-posed and less efficient. Retrieval-based approaches may be of superior choice here. However, this requires salient and robust image features, which can handle the difficulties of Angiographic images such as high level of noise and contrast variance. In this paper, we investigate state-of-the-art features of the field of computer vision regarding the applicability and reliability in the challenging scenario of Angiography ...

Mathematical models have helped shape our current understanding of the way most of our world works, especially in the physical and macromolecular world where classical physics and Newtonian mechanics has dominated for several centuries. However, there is a strong drive to seek mathematical models to explain biological phenomena. Well established engineering fields such as electrical engineering or mechanical engineering have relied on mathematical models, but due to the dynamic nature of biological systems, modeling them is more difficult. The health care industry has grown over the past decade, and the US alone spends over $2 trillion per annum and is expected to double by 2015. With an increasing population, advancements in health care, and under changing health care consumer demands, the medical industry can no long afford to wait for serendipitous events to occur such as the discovery of the small pox vaccine or the discovery of penicillin. By creating and building on simple mathematical ...

At the onset of our experiments with gemcitabine in pancreatic cancer cells, we were surprised to find that there was a large inconsistency in the published results (Fig. 1B and SI Appendix, Table S1). The same cell lines in different studies were reported as sensitive or resistant, and this was true in all 15 cell lines tested. We found that differences in sensitivity depended very strongly on the cell density (Fig. 1D), and this stands as the most likely explanation for these findings and perhaps for others in drug-profiling efforts (6). Discrepancy in experimental findings is often blamed on sloppiness and has been excoriated as part of an epidemic of irreproducible scientific experiments (51). A fairer lesson is that inconsistency may reflect the extreme sensitivity of some biological phenomena to experimental conditions. History has shown that trying to resolve these can inspire discovery, as we believe has happened here. The resolution to the discrepant findings with gemcitabine is in ...

Pterygium is a common ocular surface disease characterized by fibrovascular invasion of the cornea and is sight-threatening due to astigmatism, tear film disturbance, or occlusion of the visual axis. However, the mechanisms for formation and post-surgical recurrence of pterygium are not understood, and a valid animal model does not exist. Here, we investigated the possible mechanisms of pterygium pathogenesis and recurrence. First we performed a genome wide expression analysis (human Affymetrix Genechip, |22000 genes) with principal component analysis and clustering techniques, and validated expression of key molecules with PCR. The controls for this study were the un-involved conjunctival tissue of the same eye obtained during the surgical resection of the lesions. Interesting molecules were further investigated with immunohistochemistry, Western blots, and comparison with tear proteins from pterygium patients. Principal component analysis in pterygium indicated a signature of matrix-related structural

The paper that has been most influential to my career is most certainly Johnston, P. R., and D. H. Pilgrim (1976), Parameter optimization for watershed models, Water Resources Research, 12(3), 477-486. I read this paper during my graduate work in the early 1980s and was intrigued by their report that A true optimum set of (parameter) values was not found in over 2 years of full-time work concentrated on one watershed, although many apparent optimum sets were readily obtained.. On the one hand this paper clearly identified an important problem that needed to be addressed. On the other (as I often remark during talks on the subject), I think it was remarkable as an example of a paper reporting the apparent failure of the researchers to achieve their goals … how often do we see people reporting their failures in the literature these days :-). More of this kind of work - reporting a scientific study and accurately reporting both successes and failures … but especially failures … is ...
For statistical modeling, the model parameters are usually estimated by maximizing a probability measure, such as the likelihood or the posterior. In contrast, a variational Bayesian method threats the parameters of the model as probability distributions and computes optimal distributions for them rather than values. It has been shown that this approach effectively avoids the overfitting problem, which is common with other parameter optimization methods. This paper applies a variational Bayesian technique to surface fitting for height field data. Then, we propose point cloud denoising based on the basic surface fitting technique. Validation experiments and further tests with scan data verify the robustness of the proposed method. ...

If you have a question about this talk, please contact Lorena Escudero.. Location matters in biology. Both the inner workings of tissues and organs and their dysregulation, which leads to disease, depend on the tight web of relationships between different cell populations, and on the concerted regulation of their function mediated by genetic and environmental effects. In the last 10 years and more, it has become clear that many biological phenomena cannot be studied by analyzing cells in bulk and outside of their natural environment, but their underlying mechanisms can only be mechanistically investigated if observed both at the single-cell level and in situ. While technologies allowing either the former or the latter of these features are now available, combining both is extremely challenging, at least with the throughput necessary to obtain reliable results. In our laboratory, we have recently launched a project, named IMAXT (Imaging and Molecular Annotation of Xenografts and Tumours), that ...

Transcription factor NF-κB: Nuclear factor κB (NF-κB) was initially identified as a transcription factor that binds to the κ-light-chain-enhancer of immunoglobulins expressed selectively in B cells, but it has since been shown to be expressed by almost all cells, including the cells of invertebrates, such as urchins and fruit flies, as well as higher animals. In mammals in particular, five molecules that belong to the NF-κB family, also called as the Rel family, are known. Members of the NF-κB family are involved in various biological phenomena, such as the immune response and cell viability, through induction of expression of inflammatory cytokines, antiapoptotic factors, etc. In addition, NF-κB activation is dysregulated in various diseases, including inflammatory and autoimmune diseases, and cancer, and attention is therefore being given to NF-κB as target molecules for treatment of various diseases ...
