Preparation of briquettes from the Golden Horn bottom sediments by hydro-thermal agglomeration process.

The Golden Horn (GH) sediments, which consist mainly of clay, organic substances and heavy metals, are formed with the contribution of industrial and domestic wastes released in the Golden Horn Estuary. On account of their mineralogical and chemical composition, these sediments may be regarded as a suitable raw material for briquette production. In this study, the utilization of GH dredged bottom sediments was investigated for preparation of briquettes.

The effect of diclofenac sodium and papaverine on isolated human ureteric smooth muscle.

Objectives: The pain assocaited with ureteral obstruction is caused by a rise in intraluminal pressure above the obstruction which produces an increase in tension of the ureteral smooth muscle. A reduction in pressure will result in decreased tension and relief of pain. In this study we used papaverine and a prostaglandin synthesis inhibitor, diclofenac sodium to decrease ureteral tension and compaired their effects on isolated human ureteric smooth muscle.

Cerebrospinal fluid leptin levels in preeclampsia: relation to maternal serum leptin levels.

Background: To determine whether cerebrospinal fluid (CSF) and circulating levels of leptin differ between women with preeclampsia and women who had an uncomplicated pregnancy.
