OBJECTIVE The objective of this study was to investigate the usefulness of helical CT angiography in the evaluation of total anomalous pulmonary venous connections. MATERIALS AND METHODS Fourteen patients with total anomalous pulmonary venous connections underwent helical CT angiography and subsequent three-dimensional (3D) reconstruction. They ranged in(More)
Remodeling of extracellular matrix (ECM) is one of the key events in many developmental processes. In the present study, a temporal profile of gelatinase activities in regenerating salamander limbs was examined zymographically. In addition, the effect of retinoic acid (RA) on these enzyme activities was examined to relate the pattern-duplicating effect of(More)
When the rnpB gene encoding M1 RNA, the RNA component of Escherichia coli RNase P, is transcribed, the primary M1 RNA transcript (pM1 RNA) is produced and subsequently processed at the 3' end to generate the mature M1 RNA. To study features of pM1 RNA thought to be involved in RNA processing, systematic mutations were introduced in sequence elements and(More)
BACKGROUND Successful colonoscopy depends on insertion of the instrument to the cecum, precise observation, and minimal patient discomfort during the procedure. The aim of this prospective study was to determine whether certain variables are associated with insertion time and patient discomfort during colonoscopy. METHODS Nine hundred nine consecutive(More)
BACKGROUND To compare the surgical and oncological outcomes and morbidity of the first 50 cases treated by laparoscopic radical hysterectomy with those of the second 50 cases. METHODS Between October 1994 and January 2004, we retrospectively reviewed the charts of 100 consecutive patients (International Federation of Gynecology and Obstetrics stages IA2(More)
A previously undescribed 62-kDa protein (p62) that does not contain phosphotyrosine but, nevertheless, binds specifically to the isolated src homology 2 (SH2) domain of p56lck has been identified. The additional presence of the unique N-terminal region of p56lck prevents p62 binding to the SH2 domain. However, phosphorylation at Ser-59 (or alternatively,(More)
A plasmid-borne transposon encodes enzymes and regulator proteins that confer resistance of enterococcal bacteria to the antibiotic vancomycin. Purification and characterization of individual proteins encoded by this operon has helped to elucidate the molecular basis of vancomycin resistance. This new understanding provides opportunities for intervention to(More)
OBJECTIVE To evaluate the clinicopathologic characteristics and prognostic factors of ovarian granulosa cell tumors. METHODS Medical records of 113 patients presenting between January 1995 and December 2007 were retrospectively reviewed. RESULTS One-hundred two patients had adult type disease, with a mean age of 46.2 years (range, 18 to 83 years) and a(More)
Individuals carrying mutations in BRCA1 or p53 genes are predisposed to a variety of cancers, and both tumor suppressor genes have been implicated in DNA damage response pathways. We have analyzed a possible functional link between p53 and BRCA1 genes. Here we show that BRCA1 expression levels are down-regulated in response to p53 induction in cells that(More)
