Current Pharmaceutical Design - Volume 13, Issue 15, 2007

In recent years, biomedical research and drug design became one of the fastest growing branches of scientific and industrial development. The tremendous scale (number of projects and volume of information to process) promoted by trillions of dollars invested in these fields called for completely new approaches to obtain, analyze, and apply information to clinical practice, pharmacological research and the medical ind Read More

Cell adhesion plays a pivotal role in diverse biological processes that occur in the dynamic setting of the vasculature, including inflammation and cancer metastasis. Although complex, the naturally occurring processes that have evolved to allow for cell adhesion in the vasculature can be exploited to direct drug carriers to targeted cells and tissues. Fluid (blood) flow influences cell adhesion at the mesoscale by affecting th Read More

Hepatocellular carcinoma (HCC) is estimated to be responsible for 250,000 deaths worldwide yearly. Aggressive surgical resection or liver transplantation still remain the only viable curative options for patients suffering the disease despite the multitude of emerging therapies for HCC. However, even with the most aggressive surgical intervention, survival varies widely within each particular stage of HCC. In order to imp Read More

We describe the use of a parametric lognormal model to calculate and compare survival statistics in the clinical treatment of advanced/metastatic pancreatic, breast and colon cancers. The fit using the lognormal model explained greater than 90% (R2 ranged from 0.917 to 0.998 for a total of the 51 arms from published studies) of the variation in the cumulative survival statistics of patients treated for advanced cancers. A met Read More

The typical way of judging about either the efficacy of a new treatment or, on the contrary, the damage of a pollutant agent is through a test of hypothesis having its ineffectiveness as null hypothesis. This is the typical operational field of Kolmogorov’s statistical framework where wastes of data (for instance non significant deaths in a polluted region) represent the main drawback. Instead, confidence intervals about treatme Read More

This review is focused on mathematical modeling of behaviors of a whole organism with special emphasis on models with a clearly scientific approach to the problem that helps to understand the mechanisms underlying behavior. The aim is to provide an overview of old and contemporary mathematical models without complex mathematical details. Only deterministic and stochastic, but not statistical models Read More

Ionotropic glutamate receptors contain three subtypes: NMDA, AMPA and kainate receptors. The former two receptor subtypes have well defined roles in nociception, while the role of kainate receptors in pain is not as well characterized. Kainate receptors are expressed in nociceptive pathways, including the dorsal root ganglion, spinal cord, thalamus and cortex. Electrophysiological studies show that functional kainate Read More

Heparin is a glycosaminoglycan mixture currently used in prophylaxis and treatment of thrombosis. Heparin possesses non-anticoagulant properties, including modulation of various proteases, interactions with fibroblast growth factors, and anti-inflammatory actions. Senile dementia of Alzheimer’s type is accompanied by inflammatory responses contributing to irreversible changes in neuronal viability and brain function. Read More
