Knowledge of demographic parameters of most cetacean populations is scarce because of problems associated with sampling open populations of wide-ranging animals. In recent years, capture–recapture models have been developed to address these problems. We used a photo-identification dataset collected from a population of bottlenose dolphins Tursiops truncatus between 1999 and 2004 around 2 island...

Significant advances in our understanding of neutrophil biology were made in the past several years. The exciting discovery that neutrophils deploy neutrophil extracellular traps (NETs) to catch pathogens paved the way for a series of additional studies to define the molecular mechanisms of NET generation and the biological significance of NETosis in acute and chronic pathologic conditions. Thi...

Optoelectronic Tweezers (OET) creates patterned electrical fields by selectively illuminating a photoconductive layer sandwiched between two electrodes. The resulting electrical gradients are used to manipulate microscopic particles, including biological cells, using the dielectrophoresis (DEP) force. Previously it has been shown that up to 15,000 traps can be created with just 1 mW of optical ...

ABSTRACT The main objective of this work is to investigate the adsorption of Pyrrole 2-carboxylic acid (PCA) from O, N and C sites on the surface of pristine and Ni doped B12N12 nano cage by using density functional theory (DFT). The results of adsorption energy indicate that the adsorption of PCA on the surface of B12N12 and NiB11N12 is exoth...

helicobacter pylori has been strongly associated with peptic ulcer diseases, chronic gastritis, ulcers, and reported as a risk factor for gastric cancer, too. the vaculating cytotoxin (vaca), the cytotoxin associated genes (caga), the induced by contact with epithelium factor antigen (icea gene), blood adhesion binding antigen (baba2), and outer membrane protein oipa have been described as diff...

Acetabular reconstruction cages are indicated for severe combined segmental and cavitary acetabular bone defects. The purpose of this study was to evaluate the implications of screw placement and drill plunge and the potential insult to anatomical structures when implanting acetabular reconstruction cages. A segmental cavitary defect was reamed into the acetabulum and a cage was implanted in ea...

Impact of Atlantic salmon (Salmo salar) cage culture in Mjoifjordur, Eastern Iceland on the chemistry of the sediment was investigated. Sediment samples were collected using a Shipek grab in December 2003. A core sub-sample was taken from each grab for analyzing total organic matter, total organic carbon, total nitrogen and phosphorus in different depths from three stations at various distances...

The dispersal pattern of the sand fly Lutzomyia neivai was studied through mark-release-recapture experiments in an American cutaneous leishmaniasis endemic rural area in Southeastern Brazil. Over 6500 specimens were marked with fluorescent powder and released in forest edge and peridomicile habitats from August to November 1999, February and April 2000. Recapture attempts were made using Shann...
