A gill perfusion technique allowing control of flow and pOt in the ventral aorta and in the irrigating water is described. The procedure includes measurements of flow and pQi in the dorsal aorta and the inferior jugular vein. Pressure recordings were made in the ventral and dorsal aortas. Lowering the perfusion fluid po% and/or the irrigating water pOi increased the branchial vascular resistanc...

BACKGROUND The purpose of this study was to investigate the smear layer removal and erosive capacity of various irrigation solutions with sequential use of NaOCl on instrumented root canal walls. METHODS The root canals of single-rooted teeth were instrumented with ProTaper rotary instrument. Then, the teeth were randomly divided into five experimental groups. The root canals were irrigated w...

We report a case of acute postoperative endophthalmitis caused by vancomycin-resistant Staphylococcus hominis, treated at our hospital. An 80-year-old male presented 2 days after uncomplicated phacoemulsification and posterior chamber intraocular lens implantation, with a 24-hour history of progressive visual loss and redness in the operated (right) eye. On examination, best corrected visual ac...

Hysteroscopic procedure can be complicated by intravascular absorption of irrigating fluid. The clinical features of this complication are similar to transurethral resection of the prostate (TURP) syndrome. There have been few reports on hypocalcemia during endoscopic surgery and clinical implications of hypocalcemia in TURP syndrome have been underestimated. We report a case of TURP syndrome a...

The objective of this study was to evaluate periapical and apical repair using calcium hydroxide root canal dressings for different lengths of times in teeth with induced chronic periapical lesions. A total of 61 root canals of maxillary and mandibular premolars from 4 dogs were used. After mechanical preparation of the root canals using the crown-down technique, and 5.25% NaOCl as irrigating s...

The transurethral resection of the prostate (TURP) syndrome is a severe vascular hypotension reaction that complicates endoscopic surgery as a result of massive irrigating fluid absorption causing a drop of serum sodium concentration of >15mmol/l inducing severe acute dilution hyponatraemia (HN) of <120mmol/l [1]. Volumetric Overload Shock (VOS) is a condition caused by massive fluid infusions ...

Somatic recombination in heterozygous diploid cells may be a promotional agent of neoplasms by inducing homozygosity of defective genes. Tumor suppressor genes may in this way be completely suppressed in recombinant cells. In this work, the genotoxic effects of detergent derived from the castor oil plant (Ricinus communis) in heterozygous diploid cells of Aspergillus nidulans are evaluated. Pre...
