Transposons coding beta-lactamase with an extended spectrum of effects and resistance to other antibiotics

The authors present contemporary knowledge concerning the transposition of resistance genes to penicillins, cephalosporins and carbapenems, and transposons and integrins coding resistance to other antibacterial substances. Transposition is, together with bacterial conjugation and transduction with bacteriophages, another mechanism of mobility and restructuring of resistance genes in bacterial strains of the same and also in other bacteria.     

Different effects of cyclosporine or tacrolimus on hepatocyte acute phase proteins

We describe the MR findings in a patient with acute renal injury after blunt abdominal trauma associated with perinephric hematoma and urinoma. Both CT and MR findings are described. Active urine extravasation into a perinephric urinoma is demonstrated by serial post-contrast imaging with CT and MRI showing progressively increased attenuation/signal intensity fluid in communication with the collecting system, commencing 2 minutes after contrast administration.

Effect of Gravity and Initial Stress on Torsional Surface Waves in Dry Sandy Medium

This problem studies the effect of gravity and initial stress on the propagation of torsional surface waves in dry sandy medium. The mathematical analysis of the problem has been dealt with the Whittaker function. Assuming the expansion of the Whittaker function up to linear term, it is concluded that the gravity field will always allow torsional waves to propagate. The expansion of the Whittaker function up to quadratic terms shows that two such wave fronts may exist in the medium. Finally, it is concluded that the sandy medium without support of a gravity field cannot allow the propagation of torsional surface waves, where as the presence of a gravity field always supports the propagation of torsional surface waves regardless of whether the medium is elastic or dry sandy.
