RESUMO
OBJECTIVE: Evaluation of the effect of using a topical hemostatic agent named "ChitoHem(®)" on different factors on patients undergoing diagnostic coronary angiography. METHODS: The present blind, randomized, controlled study included 124 patients randomly divided into 2 groups. In the treatment group following femoral sheath removal, ChitoHem(®) powder and in the control group conventional hemostatic procedure was applied. RESULTS: In the treatment group, time to hemostasis, ambulation, and the use of sandbag were significantly shorter compared with the control group, respectively (4.6 ± 1.3 vs 12.4 ± 4.4 minutes, 3.5 ± 2.7 vs 23.0 ± 1.73 hours and 1.6 vs 98.4%; P < .05). There were no significant differences in hematoma formation and re-bleeding between the 2 groups. CONCLUSION: It was exhibited ChitoHem(®) topical hemostatic powder used on treatment patients undergoing diagnostic coronary angiography was statistically superior at reducing the time to hemostasis and ambulation as well as the use of sandbags compared with manual compression in control group.

The electronic transport properties of crossed carbon nanotube junctions are investigated using ab initio methods. The optimal atomic structures and the intertube distances of the junctions are obtained using van der Waals corrected density functional theory. The effect of gating on the intertube conductance of the junctions is explored, showing the charge accumulation to the nanotube contact and the charge depletion region at the metal-semiconductor Schottky contact. Finally, it is shown how the conductance of the junctions under the gate voltage is affected by pressure applied to the nanotube film.

A 40-year-old male with known hypertrophic cardiomyopathy was admitted for catheterization. At catheterization and angiography the septum was hypertrophied to about 5.5 cm and diffuse coronary artery aneurysms were revealed. We found no previous report of coronary artery aneurysm associated with hypertrophic cardiomyopathy.
