Resveratrol is a natural polyphenol with many interesting biological activities. Its pharmacological exploitation in vivo is, however, hindered by its rapid elimination via phase II conjugative metabolism at the intestinal and, most importantly, hepatic levels. One approach to bypass this problem relies on prodrugs. We report here the synthesis, characterization, hydrolysis, and in vivo pharmac...

Marine algae have attracted a great deal of interest as excellent sources of nutrients. Polysaccharides are the main components in marine algae, hence a great deal of attention has been directed at isolation and characterization of marine algae polysaccharides because of their numerous health benefits. In this review, extraction and purification approaches and chemico-physical properties of mar...

We use the topological sub-structural molecular design (TOPS-MODE) approach to formulate structural alert rules for chromosome aberration (CA) of organic compounds. First, a classification model was developed to group chemicals as active/inactive respect to CA. A procedure for extracting structural information from orthogonalized TOPS-MODE descriptors was then implemented. The contributions of ...

Abstract In this review, we have focused on analytical methods for characterizing the geographical and botanical origin of honey. We evaluated works concerning most used in analysis honey, paying particular attention to what has been last decade. investigated starting from common at beginning century, such as melissopalynological analysis, mineral profile or chemico-physical parameters, current...

Toxicology seeks to understand and quantify injurious chemico-biological interactions. The application of this understanding is prediction of the likelihood of occurrence of injury to human health or to undesirable alteration of ecological balance. The key to understanding chemical induced biological injury is development of improved methods of measuring changes in cellular function and structu...

We present a viscometric affinity biosensor for continuous monitoring of glucose in biological fluids such as blood and plasma. The sensing principle of this chemico-mechanical sensor is based upon the viscosity variation of a sensitive fluid with glucose concentration. Basically, this device includes both an actuating and a sensing piezoelectric diaphragms as well as a flow-resistive microchan...

chemico-physiological investigations in the same field of: research, published as a Smithsonian contribution the results of his labours regarding the venom of the rattle-snake. In conjunction with Dr. Iieichart, he has now completed further and still more important investigations, the particulars and results of which are embodied in the volume before us. Like all Smithsoniau contributions the b...

The development of modern omics technology has not significantly improved the efficiency of drug development. Rather precise and targeted drug discovery remains unsolved. Here a large-scale cross-species molecular network association (CSMNA) approach for targeted drug screening from natural sources is presented. The algorithm integrates molecular network omics data from humans and 267 plants an...

We propose a numerical framework that permits an effective atlas-like representation of chemico-biological space based on a series of Cartesian planes mapping the ligands with the corresponding targets connected by an affinity parameter (K(i) or related). The numerical framework is derived from the concept of ligand efficiency indices, which provide a natural coordinate system combining the pot...
