USDA-ARS scientists have made important contributions to the molecular genetic analysis of agriculturally important insects, and have been in the forefront of using this information for the development of new pest management strategies. Advances have been made in the identification and analysis of genetic systems involved in insect development, reproduction and behavior which enable the identif...

There has long been a pressing clinical need to identify prognostic and predictive factors for patients with breast cancer. Although numerous candidate biological and molecular markers have been identified during the last two decades, traditional factors such as lymph node status, tumor size, histologic type, histologic grade, and hormone receptor status remain the most useful indicators of pro...

Biological markers in nasal secretions provide valuable information on nasal pathophysiology. However, published data on biomarker concentrations in nasal fluids are remarkably inconsistent, and the bias due to different sampling techniques, has not yet been systematically evaluated. Concentrations of various protein were repeatedly determined in nasal secretions of 16 healthy volunteers. The p...

background: it is believed that bovine neutrophils contain several peptides and protein which exhibit antimicrobial activity against microorganisms such as fungi and bacteria. objectives: the purpose of this study was to isolate and purify a potential antibacterial protein from bovine neutrophil and test its anti bacterial activity. methods: neutrophils were isolated from bovine blood using dex...

New biological markers of myocardial injury have improved the management of patients with acute coronary syndromes. Among these markers, the most relevant are the cardiac troponins (troponin I and troponin T) because of their cardiospecificity, and myoglobin because of its combination of diagnostic sensitivity and usefulness for an early diagnosis. The serial analysis and combined use of both m...

Individual animals differ from each other on a number of biological levels. At the most basic level, the deoxyribonucleic acid (DNA) of each animal is different, and transcription of the DNA code yields variations at the protein level, which in turn give rise to individual diversity at the physical level. In recent years, accessing the primary genetic code of individual animals has become strai...

Tuber quality is the subject of great interest among processing industry and consumers worldwide. Being a polygenic trait, its enhancement requires systematic understanding their genetic complexity. Molecular genetics offered valuable solutions to challenging endeavours slow gains in conventional potato breeding. With advent linkage maps, molecular markers availability next-generation sequencin...
