OBJECTIVE To investigate the potential association between serum folate levels and colorectal adenoma (CRA) occurrence and recurrence. METHODS This prospective study measured baseline serum folate levels in outpatients who were screened for CRA using colonoscopy. Participants were then randomly selected to produce one group with CRA and one without CRA. These two subgroups underwent further f...

purpose: to compare outcomes and recurrence rates of amniotic membrane transplantation (amt) plus intraoperative mitomycin c (mmc) and conjunctival rotational autograft (cra) plus intraoperative mmc in pterygium surgery methods: ninety-two eyes of 92 patients with primary nasal pterygium were enrolled. all patients were randomized to undergo either amt or cra. forty-three patients underwent amt...

Corosolic acid (CRA), a pentacyclic triterpene isolated from medicinal herbs, has been reported to exhibit anticancer properties in several cancers. However, the anticancer activity of CRA in osteosarcoma cells is still unclear. In the present study, the inhibitory effect of CRA in osteosarcoma MG-63 cells was investigated, and the results revealed that CRA significantly inhibited the viability...

The community reinforcement approach (CRA) has been applied in the treatment of disorders resulting from alcohol, cocaine and opioid use. The objectives were to review the effectiveness of (1) CRA compared with usual care, and (2) CRA versus CRA plus contingency management. Studies were selected through a literature search of RCTs focusing on substance abuse. The search yielded 11 studies of ma...

purpose: to study the pattern of perfusion of central retinal artery (cra) after 0.1 ml intravitreal injection of bevacizumab to verify the need for any maneuver to decrease the intraocular pressure (iop) including anterior chamber paracentesis (acp) methods: this is a prospective, interventional, noncomparative case series. patients receiving intravitreal injection of bevacizumab for choroidal...

Lenders have increasingly responded to regulatory and public pressures to provide credit to lowerincome and minority communities by entering into CRA agreements, which typically involve pledges to extend a certain volume of lending to targeted groups and communities. This paper considers the broader impact of these CRA agreements by examining whether they are associated with changes in lending ...

The capacity of complement-mediated solubilization of immune complexes (complex releasing activity: CRA) was studied in 63 sera from eight systemic lupus erythematosus (SLE) patients. CRA in sera of active SLE (35 +/- 17.%) was significantly lower than that of inactive SLE (64.1 +/- 24.1%, P less than 0.001). In addition, 20 of 23 sera collected during active diseases demonstrated CRA values le...

Cost register automata (CRA) were proposed by Alur et all as an alternative model for weighted automata. In hope of finding decidable subclasses of CRA, they proposed to restrict their model with the copyless restriction but nothing is really know about the structure or properties of this new computational model called copyless CRA. In this paper we study the properties and expressiveness of co...

The adhE gene encodes ethanol dehydrogenase and is located at min 27.9 of the Escherichia coli chromosome. Expression of adhE is about 10-fold higher in cells grown anaerobically than in cells grown aerobically and is dependent on both transcriptional and posttranscriptional factors. In this study, a trans-regulatory element repressing adhE expression was characterized by genetic and biochemica...
