PROTICdb is a web-based database mainly designed to store and analyze plant proteome data obtained by 2D polyacrylamide gel electrophoresis (2D PAGE) and mass spectrometry (MS). The goals of PROTICdb are (1) to store, track, and query information related to proteomic experiments, i.e., from tissue sampling to protein identification and quantitative measurements; and (2) to integrate information...

Aim Detection of protein expression changes in human cystic echinococcosis sera by 2D gel electrophoresis. Background Diagnosis and successful treatment of cystic echinococcosis (CE) is a major challenge, up to now. Identification of related expressed proteins using proteomics tools and bioinformatics analysis of patients' sera have not been investigated, so far. Methods Sera from eight con...

The mzQuantML standard has been developed by the Proteomics Standards Initiative for capturing, archiving and exchanging quantitative proteomic data, derived from mass spectrometry. It is a rich XML-based format, capable of representing data about two-dimensional features from LC-MS data, and peptides, proteins or groups of proteins that have been quantified from multiple samples. In this artic...

the aim of this investigation was conducted to proteomic analysis of plasma obtained from pregnant women who destined to develop late-onset preeclampsia without intrauterine growth restriction (iugr) during 16 th week of gestation. plasma was obtained from primiparous women during 16 th week of gestation. 2-de proteomic analysis was done for plasma from 11 healthy pregnant women and 11 women wh...

Drought stress in plants, the change (increase or decrease) in the production of plant proteins. Proteomics in recent years one of the most powerful tools that help us to study the changes in protein In order to investigate the proteome of wheat leaves in response to terminal drought, two genotypes susceptible and resistant wheat genotypes were evaluated under irrigated (non-stress) and rain-fe...

Parasites with complex life cycles have developed numerous and very diverse adaptations to increase the likelihood of completing this cycle. For example, some parasites can abbreviate their life cycles by skipping the definitive host and reproducing inside their intermediate host. The resulting shorter life cycle is clearly advantageous when definitive hosts are absent or rare. In species where...

The arachnid taxon Tetrapulmonata Shultz, 1990, includes those orders which have, at least primitively, two pairs of book lungs, i.e. Trigonotarbida, Araneae, Amblypygi and Uropygi (Selden et al., 1991). It includes the most familiar living arachnids (spiders) and one of the most abundant Palaeozoic groups (trigonotarbids). Among the arachnids, book lungs are widely accepted as the most primiti...

Metazoans are largely made of repeated parts, and metazoan evolution is marked by changes in the number of these parts, called meristic evolution. Understanding the mechanisms associated with meristic changes is thus a critical issue to evolutionary developmental biology. Palatal rugae are sensory ridges regularly arranged on the hard palate of mammals. They develop sequentially following mesio...

Theoretical models predict that genetic relatedness affects the competition within and between parasite clonal groups sharing a common host. Here, we studied natural and experimental multiple infections of the trematode Coitocaecum parvum in its intermediate host. We focused on the effects of clonality on the life-history strategy of parasites competing for resources. Coitocaecum parvum can eit...
