Experimental study of mono and hybrid nanofluids on square pyramid solar still.

The lower productivity of square pyramid solar still is the prime impediment to its worldwide applicability. In the present study, efforts have been made to improve the productivity of square pyramid solar still using mono and hybrid nanofluid. The experiments were carried out with two similar square pyramid solar stills at a 1cm depth of basin fluid (saline water, mono, and hybrid nanofluid) under the climate of location (20.

Acute Psychotic Episode Precipitated by Opioid Withdrawal in a Case of Bipolar I Disorder.

Psychosis is a state of mind where an individual loses touch with reality and cannot differentiate between their perceptions and the real world. They experience one or more of the following: delusions, hallucinations, disorganized speech or catatonic behavior. While it can have a sporadic onset, drug-induced psychosis is also very common.

Extensive fatal intracoronary thrombosis during percutaneous coronary intervention with bivalirudin.

The authors describe 2 cases of extensive intracoronary thrombus formation leading to acute closure of the left main where bivalirudin (Angiomax) was used as the anticoagulant during percutaneous coronary intervention leading to mortality. Both cases had similarity in the cascade of complications of coronary dissection leading to slow flow and prolonged procedure time with compromise of antegrade flow in the coronary artery and a final catastrophic development of extensive intracoronary thrombosis extending into the left main and nonintervened vessel (left anterior descending or circumflex) followed by ventricular fibrillation and death. Bivalirudin has reversible anticoagulant pharmacodynamics because the bivalirudin molecule is cleaved by the thrombin molecule.

Pronto catheter thrombectomy in acute ST-segment myocardial infarction: a case series.

Primary angioplasty has emerged as the treatment of choice in acute ST-elevation myocardial infarction. While the timely restoration of infarct artery patency is central, close attention needs to be paid to microvascular integrity for successful restoration of normal myocardial metabolism. Clearance of thrombus burden is central to restoring normal myocardial metabolism.

Power injection of contrast media via peripherally inserted central catheters for CT.

Purpose: To evaluate patient safety, catheter rupture rates, and computed tomography (CT) image quality when using peripherally inserted central catheters (PICCs) in vivo for the power injection of CT contrast media at standard injection rates.

Materials And Methods: A prospective study to evaluate the safety and effectiveness of power injection of contrast media via indwelling PICCs was performed. Single-lumen and double-lumen polyurethane PICCs (5 F) were injected in vivo with contrast media for clinical CT examinations at injection rates ranging from 1 mL/sec to 4 mL/sec.

Transcatheter coil embolization of large pulmonary artery pseudoaneurysms in a child.

The authors report a case of a 5-year-old boy who initially presented with mastoiditis, underwent successful surgical treatment, and during the immediate postoperative period developed multiple, bilateral pulmonary artery pseudoaneurysms. The large size and multiplicity of the pseudoaneurysms precluded the patient from undergoing thoracic surgery. Successful endovascular coil and wire embolization was performed in a staged set of procedures with use of more than 30 m of wire and coils.
