The predictive value of R-wave peak time on no-reflow in patients with ST-elevation myocardial infarction treated with a primary percutaneous coronary intervention.

Background: Coronary no-reflow (NR) is a dreadful complication of primary percutaneous coronary intervention (pPCI) that is seen in nearly 50% of cases. A great effort is being done to discover simple tools that could predict such a complication. We aimed primarily to study the predictive power of R-wave peak time (RWPT) on NR.

Effect of diuresis on extracorporeal shockwave lithotripsy treatment of ureteric calculi.

Objective: To evaluate the effect of diuresis during extracorporeal shockwave lithotripsy (ESWL) treatment of ureteric calculi. The purpose is to improve stone fragmentation and clearance rates.

Materials And Methods: One hundred and six consecutive patients with ureteric calculi at different levels were treated by ESWL using Siemens Lithostar 2 machine.

Biomonitoring of n-nitroso compounds, nitrite and nitrate in the urine of Egyptian bladder cancer patients with or without Schistosoma haematobium infection.

The excretion of nitrate, nitrite, apparent total N-nitroso compounds and volatile nitrosamines was measured in 24 hr urine from 61 Egyptians, divided into 4 groups: controls, Schistosoma haematobium-infected patients and bladder cancer patients with and without a history of schistosomal infection. Urinary nitrate in S. haematobium-infected patients was significantly higher than in the other 3 groups.

O6-alkylguanine-DNA alkyltransferase activity in schistosomiasis-associated human bladder cancer.

O6-Alkylguanine-DNA-alkyltransferase (ATase) activity was measured in extracts of 55 bladder tissue samples (46 tumour and nine uninvolved mucosal tissue) from Egyptian patients with schistosome-associated bladder carcinoma. Activity varied from 2.0 to 16.
