OBJECTIVES Although human T-cell lymphotropic virus type 1 (HTLV-1)-associated uveitis has been well recognized in Japan, related studies in Brazil are scarce. We performed a serologic survey for HTLV-1 infection among patients with uveitis and investigated the ocular findings in HTLV-1-asymptomatic carriers. METHODS One hundred ninety serum samples from patients with uveitis of determined (n...

Future military waveforms are most probably implemented on software defined radios capable to handle several waveforms. Implementation of several waveforms would require design of several receiver chains. In order to ease these design tasks, this paper describes a universal frequency domain baseband receiver structure. The structure may be used as a starting point to design receiver basebands f...

Hereditary alpha-1-antitrypsin (α1-AT) deficiency predisposes to pulmonary emphysema. The objective of this study is to demonstrate the limitations of some laboratory methods used in the study of the deficiency, and which may produce errors in interpretation and detection of uncommon alleles. Two clinical cases are described: the index patient, who had pulmonary emphysema with α1-AT levels less...

The degradation of 100 nm effective channel length pMOS transistors with 14 A equivalent oxide thickness JVD Si3N4 gate dielectric under hot-carrier stress is studied. Interface-state generation is identified as the dominant degradation mechanism. Hot-carrier-induced gate leakage may become a new reliability concem. Hot-carrier reliability of 14 A Si3N4 transistors is compared to reliability of...

objective(s):solid dispersion formulation is the most promising strategy to improve oral bioavailability of poorly water soluble drugs. the aim of this study was to compare the effect of polyvinylpyrrolidone k30 (pvp) and poloxamer-188 (plx) as carrier in solid dispersion formulations of celecoxib (clx). materials and methods: solid dispersions of clx:pvp or clx:plx were prepared at different r...

Since the recognition of asymptomatic bacteriuria (ABU), several studies have questioned its significance. It is a very common condition, observed in many healthy individuals. Current guidelines mandate that ABU should not be treated in all cases, as it does not seem to improve the outcome. Conditional restrictions for treatment of ABU can be relaxed in certain situations, with minimal exceptio...

Tropheryma whipplei, the causative agent of Whipple's disease, is associated with various clinical manifestations as well as an asymptomatic carrier status, and it exhibits genetic heterogeneity. However, relationships that may exist between environmental and clinical strains are unknown. Herein, we developed an efficient genotyping system based on four highly variable genomic sequences (HVGSs)...

parasitic colitis, especially entamoeba histolytica, is a well-known disorder in the middle east particularly in iran. the carrier state of the disease or the chronic type frequently remains undiagnosed or mistaken as irritable bowel syndrome which results in further discomfort and increases the incidence of associated complain. we devised a technique by inserting bisacodyl suppository and then...
