The widespread incidence of H5N1 influenza viruses in bird populations poses risks to human health. Although the virus has not yet adapted for facile transmission between humans, it can cause severe disease and often death. Here we report the generation of combinatorial antibody libraries from the bone marrow of five survivors of the recent H5N1 avian influenza outbreak in Turkey. To date, these libraries have yielded >300 unique antibodies against H5N1 viral antigens. Among these antibodies, we have identified several broadly reactive neutralizing antibodies that could be used for passive immunization against H5N1 virus or as guides for vaccine design. The large number of antibodies obtained from these survivors provide a detailed immunochemical analysis of individual human solutions to virus neutralization in the setting of an actual virulent influenza outbreak. Remarkably, three of these antibodies neutralized both H1 and H5 subtype influenza viruses.

This study can help to evaluate the involvement of GO in early period with MRI added DWI.

Our study revealed that over half of patients with acromegaly had SDB. Furthermore, SDB severity decreases with acromegaly treatment; however, this decrease does not change the indication for PAP therapy; therefore, PAP therapy should not be delayed in acromegalic SDB patients.

The aim of our study was to determine the rate of elevation of c-reactive protein in cancer patients and to evaluate its correlation with other acute phase proteins. A total of 104 patients with various types of cancer who admitted clinic were included in our study. Serum levels of c-reactive protein, lactate dehydrogenase, ferritin, haptoglobin, plasma fibrinogen levels and erythyrocyte sedimentation rate were measured. The serum levels of c-reactive protein was found to be increased in 74% of cancer patients, with 81.3% and 64.4% in metastatic and non-metastatic group, respectively. Our study showed that c-reactive protein and fibrinogen demonstrated better characteristics than other acute phase proteins to differentiate between cancer patients and healthy individuals and also to differentiate between healthy individuals and patients with infection. C-reactive protein, ferritin, fibrinogen, erythrocyte sedimentation rate, and haptoglobin showed similar characteristics to differentiate metastatic and non-metastatic cancer patients whereas, LDH demonstrated the lowest performance. C-reactive protein was not found to be superior to other acute phase proteins in the differential diagnosis of cancer and infection and in differentiating early stage disease from advanced stage.
