Since the first report of HIV/AIDS in India in 1986, continuous serosurveillance has been undertaken in all Indian states. Recently, five cases of HIV-2 infection have been detected in Calcutta, situated in the eastern part of India. The full-length envelope gene (2.5 kb) of one of the strains was amplified, cloned, and sequenced. Phylogenetic analysis of the Calcutta HIV-2 envelope revealed a close relatedness to the HIV-2 Rod sequence isolated in offshore Senegal. This strain, however, showed a genetic diversity of 13.5% to other Indian HIV-2 isolates. 相似文献

Background
It is difficult to obtain adequate tissue sample for diagnosing autoimmune pancreatitis (AIP) with the help of traditional EUS-guided FNA. As per ICDC guidelines, EUS-guided FNA is not recommended for diagnosing AIP(1). We herein present a report of 2 cases of using a new flexible 22 gauge (G) core biopsy needle (SharkCore, Medtronic, Sunnydale, Calif) for diagnosing AIP.Methods
This is a report of 2 cases reviewed retrospectively which had used 22G core biopsy needle for obtaining histo-pathological samples for diagnosing AIP. The cases were reviewed with both endoscopist and a pathologist to determine if the diagnostic criteria were met.Results
Both the cases had adequate tissue sample obtained to make a clear diagnosis of AIP. Pathology showed changes of chronic pancreatitis with atrophy and storiform pattern of fibrosis with a dense lymphoplasmacytic infiltrate in both cases along with identification of IgG4 cells.Conclusion
EUS-guided fine needle biopsy (FNB) using the SharkCore needle can be used reliably for diagnosing AIP. More studies need to be performed to validate this further. 相似文献45.

Localizing the sites of infection in the body is possible in nuclear medicine using a variety of radiopharmaceuticals that target different components of the infective and inflammatory cascade. Gamma(γ)-emitting agents such as [67Ga]gallium citrate were among the first tracers used, followed by development of positron-emitting tracers like 2-deoxy-2-[18F]fluoro-D-glucose (18F-FDG). Though these tracers are quite sensitive, they have limited specificity for infection due to their concentration in sites of non-infective inflammation. White blood cells (WBC) labelled with γ or positron emitters have higher accuracy for differentiating the infective processes from the non-infective conditions that may show positivity with tracers such as 18F-FDG. We present a pictorial review of potential clinical applications of PET/CT using 18F-FDG labelled WBC. 相似文献

A preliminary comparative measurement between particle imaging velocimetry (PIV) and laser speckle contrast analysis (LASCA) to study pulsatile flow using ventricular assist device in a patient-specific carotid artery phantom is reported. These full-field optical techniques have both been used to study flow and extract complementary parameters. We use the high spatial resolution of PIV to generate a full velocity map of the flow field and the high temporal resolution of LASCA to extract the detailed frequency spectrum of the fluid pulses. Using this combination of techniques a complete study of complex pulsatile flow in an intricate flow network can be studied.OCIS codes: (100.0100) Image processing, (170.0170) Medical optics and biotechnology, (230.0230) Optical devices, (290.0290) Scattering 相似文献
