Palindromic units (PUs) are intergenic repeated sequences scattered over the chromosomes of Escherichia coli and several other enterobacteria. In the latter, IS1397, an E. coli insertion sequence specific to PUs, transposes into PUs with sequences close to the E. coli consensus. Reasons for this insertion specificity can relate to either a direct recognition of the target (by its sequence or it...

The main target in the treatment of proximal ureteral stones (PUS) is to provide a high stone-free rate (SFR) with low morbidity. In this study, we aimed evaluate need for flexible ureteroscopy (URS) by retrospectively examining one surgeon’s two-year experience URS PUS center where ureteroscope and holmium laser lithotriptor are available.

was fluctuating, so evidently contained fluid, and as it had recently become painful, presumably pus. A long incision was made through the tumour, and a large quantity of pus was evacuated, mixed with which was a lot of short hair, like a handful of cropped hair on washing out the cavity, it was found to contain three or four long hairs, whose roots wore firmly fixed to the base of the tumour. ...

We deene the SAS + planning formalism, which generalizes the previously presented SAS formalism. The SAS + formalism is compared with some better-known propositional-planning formalisms with respect to expres-siveness. Contrary to intuition, all formalisms turn out to be equally expressive in a very strong sense. We further present the SAS +-PUS planning problem which generalizes the previously...

A 60-year-old woman presented with intermittent lowgrade fever and chills for 1 month accompanied by right flank soreness, poor appetite and marked body weight loss (12 kg within 1 month). Leukocytosis (WBC = 17.75 × 109/l), normocytic anaemia (haemoglobin 6.6 g/dl) and pyuria were noted. Abdominal computed tomography (CT) showed an enlarged right kidney with dilated collecting system filled wi...

The reasons for using sterilized pus in the place of autogenous or other vaccines are : 1. The great simplicity and cheapness. 2. The pus is truly autogenous, this is not so with vaccines prepared from organisms grown on artificial media; for the organism is changed by such growth. 3. Besides the bacteria, pus contains toxins, and antibodies both extremely useful for therapeutic inoculation. Th...

OBJECTIVES To identify the impact of pressure ulcers (PUs) and PU interventions on health-related quality of life (HRQL). DESIGN Systematic review and metasynthesis of primary research reporting the impact of PU and PU interventions on HRQL according to direct patient reports. Quality assessment criteria were developed and applied. Data extraction identified findings in the form of direct quo...

Objective: This study was carried out to find out the extent of MRSA in hospitalized patients in Military Hospital Rawalpindi. Methodology: It is a prospective cross sectional descriptive study based on the records of admitted patients in Military Hospital Rawalpindi during June 2005 to September 2005. Non-consecutive non-duplicate clinical isolates of MRSA, isolated from different clinical sam...
