Microarray technology is a miniaturized biotechnological tool with potential applications for study and analysis of multiple molecular compounds as proteins, lipids, carbohydrates or nucleic acids. The nucleic acids microarray technology focuses interest of scientists for fifteen years because of its huge potential as regard to the scientific research, clinical diagnosis, and development of new drugs. Only DNA microarrays are investigated in this paper. Born from the conjunction of micro-electronics, biochemistry, molecular biology, and image processing, microarrays allow to analyse several thousands of genetic information simultaneously. Thanks to this new tool, it is possible in parallel to identify, to even proportion, a considerable number of nucleic acid sequences contained in a biological sample (blood, biopsy, water, food, etc). This article proposes, after having considered the operating mode of the microarrays, to understand their quality standards as well as their advantages and disadvantages. The two following parts are devoted to the place the microarrays occupy in scientific research and in the establishment of a clinical diagnosis. Finally the last part evaluates prospects the microarrays offer in veterinary sciences. [less ▲]

Conventional sampling systems cannot localize information by smallforest units such as a compartment or a stand unless we increase the sampling intensity and the cost too. When management becomes more intensive the "unit area inventory" based upon sampling inside compartments is considered for giving in-place information about individual stand units (inventory) and their specific treatment. The authors present some procedures they have used in intensively managed forests. Individual stands are identified and mapped, then estimates are made of volume, species, structure by means of temporary plots or angle count samples systematically located or left to judgment. Computer programs have been written in order to assist the manager in applying such a type of inventory. [less ▲]

The use of meal from the crushing of Jatropha curcas seed for livestock feed is limited owing to the variable amounts of seed available. This availability depends on the level and variety of toxic and antinutritional compounds contained in the seed at a given time; the most important of these compounds are phorbol esters and curcin. The phorbol esters present in J. curcas seed are euphorbiaceae diterpenes, known for their inflammatory action resulting in irritation and toxicity to insects, fish and mammals. These compounds are sometimes completely degraded in soil and they may be reduced by physical, chemical or biological processes, with a reduction ratio of between 50 and 95%. Curcin is an irritating toxalbumin with lectin activity; it is inactivated by heat treatment at 121 °C for 30 min. Other antinutritional compounds are also present in J. curcas seed, such as saponins and an inhibitor of trypsin activity. This trypsin-inhibiting compound interferes with the digestion process and its reduction is achieved through thermal, chemical or biological treatments. The elimination of, or at least a reduction in the levels of, these molecules represents a rerequisite for using J. curcas meal in the livestock feed sector. [less ▲]
