We present a rare case of emphysematous cystitis associated with an emphysematous pyelonephritis in a diabetic Arab man who was admitted in a confusional state. A 60-year-old man was admitted to the emergency department with confusion and hypogastric mass. The Clinical examination found comatose patient with a mass in the tympanic hypogastric percussion. The pelvic computed tomography (CT) demo...

A Chandra observation has defined the extent of the SNRB0454-692 in the LMC H II region N9. The remnant has dimension 2.3× 3.6 and is elongated in the NS direction. The brightest emission comes from a NS central ridge which includes three bright patches. There is good agreement between X-ray and [O III] and [S II] morphology. The remnant is old enough so that optical data give more information ...

The X-ray observations of SN 1987A over the previous 20 years have seen the emergence of soft X-rays from the interaction of the explosion shock wave with the ambient medium. This shock wave is now interacting strongly with the inner ring and might have passed already the highest density regions. The emission can be described by thermal models with temperatures of ∼0.28 keV and ∼2.8+0.7 −1.0 ke...

We report the hard X-ray properties of the young Crab-like LMC pulsar PSR B0540-69, using archival RXTE PCA (2 – 60 keV) and RXTE HEXTE (15 – 250 keV) data. Making use of the very long effective exposure of 684 ks, we derived a very detailed master pulse profile for energies 2 – 20 keV. We confirm the broad single-pulse shape with a dip in the middle and with a significant fine structure to the...

According to general relativity, the trajectories of light rays can be bent by gravitational fields. Massive objects can therefore gravitationally “lens” the images of objects behind them. A cosmological examples of gravitational lensing is lensing of galaxies or quasars at redshifts z ∼ 1 by elliptical galaxies or galaxy clusters along the line of sight. If the lensing is “strong,” then there ...

Various lectins have attracted attention as potential microbicides to prevent HIV transmission. Their capacity to bind glycoproteins has been suggested as a means to block HIV binding and entry into susceptible cells. The previously undescribed lectin actinohivin (AH), isolated by us from an actinomycete, exhibits potent in vitro anti-HIV activity by binding to high-mannose (Man) type glycans (...

soil samples were collected from seven sites in and around the metropolitan area of mexicocity. the locations were chosen as possible sources of fugitive dusts which contribute to suspended particulate matter in the atmosphere of mexico city. x-ray fluorescence (xrf) was used to determine the concentrations of several major elements (si, k, ca, ti, mn, and fe), as well as of other trace element...

A case of idiopathic plasmacytic lymphadenopathy with hyperimmunoglobulinemia is reported. A 71-year-old man was admitted to the hospital because of the abnormal shadow on chest roentgenogram. Chest X-ray taken on admission showed remarkable diffuse infiltration and pleural thickening. Laboratory examinations revealed an elevated total protein level of 10.1 g/dl, and a gammaglobulin level of 7....
