A new termite species, , is described from northeastern Brazil. The winged imago of is distinguished from most congeners by the lack of arolia and the multiple branches connecting the median vein to the radial sector. The soldier is unique among South American by its cuboidal head capsule and very rugose postclypeus.

The first effects of this institutional measure are assessed in the present work, based on the identification and analysis of the time elapsed between fast track requests by the Ministry of Health or through petition by the depositors themselves. The results demonstrate that the INPI was able to successfully respond to the public health emergency by granting patents on average 5.

However, spatial effects on the qualitative and quantitative compositions of these substances in Neotropical termites are poorly known. Hexane extracts of heads and the defensive secretion of soldiers of Constrictotermes cyphergaster from four localities in Northeast Brazil were analyzed by gas chromatography and mass spectrometry.

Among the patentability requirements, understanding how to comply with the inventive step is especially important for patent applicants. Regarding mAbs, due to the high affinity and specificity for their molecular therapeutic target, minimal structural changes can lead to unexpected properties, being a common issue among Patent Offices.

Methods: The information was obtained through interviews with direct participants in the wild bird trade chain.
Wood is the main dietary item for most termites; however, supplementation with certain nutrients may occur via the ingestion of other available food resources in the ecosystem. The objective of this study was to evaluate the consumption of lichens with different C, N, and P contents by under laboratory conditions, and estimate the intake of this substrate by this species in a semi-arid area of Northeast Brazil. The foraging activities of fifteen field colonies were monitored over 15 days from 6:00 p.

The objective of this study was to evaluate the population structure of in arboreal nests and to estimate their contribution to the consumption of wood litter in an area of Caatinga, a type of seasonally dry tropical forest located in the Brazilian semi-arid region. The populations of fifteen nests were quantified and separated into castes, "larvae", and eggs.

Several authors and organizations have challenged this classification to recognize countries that have reached an intermediate stage of social and economic development. As proposed by Morel and collaborators in 2005, the concept of Innovative Developing Countries (IDCs) defines a group of nations with impactful scientific programs.

The agencies responsible for granting such patents, namely the Brazilian National Patent and Trademark Office (INPI) and the Brazilian National Health Surveillance Agency (Anvisa) cite technical and administrative reasons for the backlog. However, little research has focused on the economic impacts for health due to the inefficiency of the Brazilian patent system.

In the Brazilian semiarid region can be highlighted the use of the termite Nasutitermes corniger for the treatment of various diseases. This study evaluated the ethanol extract of N.
View Article and Find Full Text PDFTermites are mainly known for damage caused to human beings, both in urban and rural areas. However, these insects play an important role in the decomposition of organic matter in tropical regions and are important natural resources, which are widely used in traditional medicine and are also consumed by human populations in several parts of the world. This study aimed to catalogue termite species used worldwide through a literature review, characterizing them by its human populations' use.

The Titanosauria were much diversified during the Late Cretaceous, but paleobiological information concerning these sauropods continues to be scarce and no studies have been conducted utilizing modern methods of community analysis to infer possible structural patterns of extinct assemblages. The present study sought to estimate species richness and to investigate the existence of structures in assemblages of the South American Titanosauria during the Late Cretaceous. Estimates of species richness were made utilizing a nonparametric estimator and null models of species co-occurrences and overlapping body sizes were applied to determine the occurrence of structuring in this assemblages.

Parasites are natural regulators of their host populations. Despite this, little is known about variations in parasite composition (spatially or temporally) in environments subjected to water-related periodic stress such as the arid and semiarid regions. The objective of this study was to evaluate the spatial-temporal variation in endoparasite species' abundance and richness in populations of Neotropical Cnemidophorus ocellifer, Tropidurus hispidus, and Tropidurus semitaeniatus lizards in the semiarid northeast of Brazil.

To this end, an understanding of the integrated way in which the various actors who produce scientific knowledge and inventions in technological areas of interest operate, where they are located and how they relate to one another is of great relevance. Tuberculosis has been chosen as a model for the present study as it is a current challenge for Brazilian research and innovation.

Based on a literature review showing the specificities of patenting in the industry, the article provides a brief history of drug patents in Brazil, a discussion of patentable and non-patentable inventions, and the modalities and traits of patent protection that aim to extend the temporary monopoly granted under the patent. Such strategies include patents targeting polimorphs and optical isomers of drugs and drug combinations and specific clinical preparations, increasingly present in the drug patent claims filed by pharmaceutical companies.
