These dissimilar results may be due to chemical differences between them. Thus, we demonstrated that 1 and 2 seem to be promising spasmolytic agents, although further studies are required GS-9973 in vitro to elucidate the spasmolytic action mechanism.”
“Aims: To evaluate the prognostic value of immunohistochemical
expression of Bcl-2 in colon cancers.
Patients and methods: Two hundred and twenty-six resected and paraffin-embedded colon carcinomas were analysed by immunostaining using monoclonal antibodies for Bcl-2. We evaluated whether the Bcl-2 staining patterns, semi-quantitatively assessed, could be correlated with the pTNM stage, size and tumour circumference, differentiation, appearance, vascular invasion, perineural invasion, colloid Dactolisib purchase component, margins, involvement of adjacent structures, stromal appearance, flow cytometry and the S-phase.
Results: Eighty patients (36%) were considered Bcl-2 positive. The extent of Bcl-2 expression by tumour cells decreased significantly with respect to increasing tumour size (P = 0.042), the extension of parietal. invasion pT (P 0.007), the invasive
nature of the tumour (P = 0.024), and extent of the circumference (P = 0.024). In a multivariate analysis, Bcl-2 expression does not appear as an independent prognosis factor in the overall population as in the 166 patients with optimal resection. Of the 59 stage II patients, using univariate analysis, Bcl-2 appears to be predictive of relapse-free survival (P = 0.025) but not of overall survival (P = 0.09).
Conclusion: The loss of Bcl-2 expression appears to be correlated with increase in number of relapses in the stage II colon cancers and could be a potential useful additional histo-prognostic marker in therapy decision making.
Bcl-2 immunodetection seems to be associated with slower local tumour growth. (C) 2008 Elsevier Ltd. All rights reserved.”
“Objective: The pathophysiology of anterior cruciate ligament (ACL) rupture leading to knee osteoarthritis (OA) remains largely unknown. selleckchem It seems that bone loss occurs after ACL rupture. The purpose of our study was to determine bone mineral density (BMD) changes in the knee after ACL rupture during 2-year follow-up period and to compare BMD changes between the injured and healthy contralateral knee.
Design: Patients were included in an observational prospective follow-up study within 6 months after ACL trauma and evaluated for 2 years. Patients were treated operatively or non-operatively. At baseline and at the one- and 2-year follow-ups, BMD was measured in six regions of the tibia and femur for both knees (medial, central, lateral) using a Dual-energy X-ray Absorptiometry (DXA) scanner.
Results: One hundred forty-one patients were included, with the following characteristics: 66% were male, median age at baseline was 25.3 (inter-quartile range 11.3) years, and 63% were treated operatively.
