background: closure of patent ductus arteriosus (pda), ventricular septal defect (vsd) and atrial septal defect (asd) can be done surgically or by device. this study was designed to compare the total cost of surgical or device closures of pda, asd or vsd for iranian patients. methods: this is a cross-sectional study, conducted from january 1, 2005 until january 1, 2006 in two large heart center...

in this paper we will generalize  some of known results on the tight closure of an ideal to the tight closure of an ideal relative to a module .

purpose : to describe a case of acute angle-closure glaucoma associated with oral topiramate (topamax, aria daroo) therapy case report: two weeks after initiation of oral topiramate therapy for epilepsy, a 35-year-old woman presented with blurred vision and headache. intraocular pressure in both eyes was significantly elevated and her visual acuity was 20/30 ocular uterque (ou). bilateral conju...

oro-antral communication and fistula can occur as a result of inadequate and improper treatment. inadvertent communication with the maxillary sinus can occur during certain surgical procedures in the maxillary posterior region. though, spontaneous healing may occur in defects which are smaller than 2 mm but larger communications require immediate attention and should be treated without delay, i...

background pilonidal disease is a common condition that affects younger people in which over half of the affected patients present with a sacrococcygeal abscess. this study was performed to compare the outcome of excision and primary closure with that of rhomboid excision and flap procedure in patients with uncomplicated pilo­nidal disease. methods a total of 90 consecutive patients with piloni...

We deene the notion of weak relative pseudo-complement, and we show that, for an arbitrary lattice, the property of weak relative pseudo-complementation is strictly weaker than relative pseudo-complementation, but stronger than pseudo-complementation. Our main interest for this notion is in relation with the theory of closure operators. We prove that if a complete lattice L is completely inf-di...

T he optimal secondary prevention strategy in patients presenting with a cryptogenic stroke or transient ischemic attack (TIA) and a patent foramen ovale (PFO) is uncertain. In the United States, closure of a PFO using a percutaneous transcatheter device is currently considered investigational by the Food and Drug Administration. Nonetheless, many patients in this setting are treated off-label ...

background trocar site, incisional hernia is one of the serious complications of laparoscopic surgery. as a result, many surgeons prefer to close the fascia, especially in those sites where a trocar of 10 mm in size or larger has been inserted. on the other hand, suturing the fascia may lead to damage of other tissues, such as the intestines; hence, some surgeons prefer not to close the fascia....

In this paper are introduced some concepts of interval-valued fuzzy relations and some of their properties: reflexivity, symmetry, T-transitivity, composition and local reflexivity. The existence and uniqueness of T-transitive closure of interval-valued fuzzy relations is proved. An algorithm to compute the T-transitive closure of finite interval-valued fuzzy relations is showed. Some propertie...
