regarding the increasing numbers of iv drug addicts, the incidence of infected pseudoaneurysm is increasing. so far, different therapeutic strategies have been tried, but each method has its own drawbacks. therefore, discovering an appropriate therapeutic method is necessary. 65 patients with infected pseudoaneurysm due to drug injection referred to shohada medical center from feb 1994 till oct...

hemorrhoid is one of the most common surgical diseases and different methods are available for its treatment. this study is a comparison between two methods of treatment of internal hemorrhoid, monopolar low voltage instrument (ultroid) and rubber band ligation. this method has been carried out prospectively in which 50 patients who were treated with rubber band ligation and 50 patients with ul...

L-Selenocysteine (Sec or U) has been called the “21st amino acid”.1 Like the twenty common amino acids, selenocysteine is inserted during the translation of mRNA and has its own tRNASec and codon, UGA. This codon also serves as the opal stop codon. Decoding a UGA codon as one for selenocysteine requires a special structure in the 3′ untranslated region of the mRNA called a selenocysteine insert...

DNA ligation is essential to many molecular biology manipulations, but this reaction is often carried out by following generic guidelines or by trial and error. Maximizing the desired ligation product is especially important in DNA library construction for directed evolution experiments since library diversity is directly affected by ligation efficiency. Here, we suggest that display vectors th...

Measurements of cerebral blood flow (CBF) were made in anaesthetized baboons before and after ipsilateral carotid artery ligation and also after bilateral carotid ligation. Results showed that at normocapnia (PaCO(2) 38-39 mmHg) there was little change in cerebral blood flow on ipsilateral carotid ligation, but when both carotid arteries were tied the blood flow to the brain fell significantly....

OBJECTIVES To compares the effectiveness and impact of high inferior mesenteric artery (IMA) versus low IMA ligation on 5-year survival, lymph node yield rates, and peri-operative morbidity and mortality.  METHODS The databases of Educational Resources Information Centre (ERIC), the Web of Science, EBSCO and MEDLINE were searched using MeSH terms 'colorectal cancer', 'inferior mesenteric arte...

To examine the very initial step that takes place immediately after tissue injury and is linked to tissue regeneration, we employed the submandibular gland (SMG), which was injured by ligation of its main excretory duct (MED). Ligation of the MED of the SMG in mice induced the expression of Sca-1, a protein marker of hematopoietic stem cells. In the normal gland, a low level of Sca-1 was expres...

BACKGROUND Endoscopic band ligation is the treatment of choice for bleeding esophageal varices. However it is not clear if this procedure is associated with less early and late mortality than sclerotherapy. AIM To assess rates of re-bleeding and mortality in cohorts of patients with bleeding esophageal varices treated with endoscopic injection or band ligation. PATIENTS AND METHODS Analysis...

Ligation of FcgammaR concurrent with LPS stimulation of murine macrophages results in decreased IL-12 and increased IL-10 production. Because PI3K deficiency has been associated with increased IL-12, we hypothesized that PI3K was central to the anti-inflammatory effect of FcgammaR ligation on TLR-induced IL-12. FcgammaR ligation of macrophages increased pAKT, a correlate of PI3K activity, above...
