Only a small proportion of interspecific pollen transfer could be recorded. We explain these outcomes by specific pollinator behaviour such as floral preference and constancy during a foraging bout. This may be linked to different reward regimes of the studied Aeonium species. (C) 2009 Elsevier GmbH. All
“Introduction Changes in arterial pressure due Bromosporine price to respiratory phases have been used to predict fluid responsiveness in a number of species and pulse pressure variation (PPV) and systolic pressure variation (SPV) are commonly used. The relationship between PPV and SPV has not been described in horses. Objectives To describe and compare PPV and SPV values of horses under general anesthesia. Methods Twenty-six horses undergoing general anesthesia and receiving mechanical ventilation were enrolled in the study. Recordings of maximal and minimal values of pulse pressure and systolic pressure were calculated every 15 minutes throughout surgery. Results Initial PPV was 15.6% (7.9, 33.8) and decreased over the first 30 minutes Epigenetics inhibitor to 10.7 +/- 7.2% (P = 0.03). Initial SPV was 10.3 +/- 2.6% and decreased over the first 30 minutes to 7.3 +/- 3.3% (P = 0.004). PPV and SPV had a correlation coefficient of
0.52 (P < 0.0001) and a 95% limits of agreement from -7.1% to 14.4%. Conclusion PPV and SPV measurements in horses do not have strong agreement.”
“Background: Annexin A1 (ANXA1) is a protein related with the carcinogenesis process and metastasis formation in many tumors. However, click here little is known about the prognostic value of ANXA1 in breast cancer. The purpose of this study is to evaluate the association between ANXA1 expression, BRCA1/2
germline carriership, specific tumor subtypes and survival in breast cancer patients. Methods: Clinical-pathological information and follow-up data were collected from nine breast cancer studies from the Breast Cancer Association Consortium (BCAC) (n = 5,752) and from one study of familial breast cancer patients with BRCA1/2 mutations (n = 107). ANXA1 expression was scored based on the percentage of immunohistochemical staining in tumor cells. Survival analyses were performed using a multivariable Cox model. Results: The frequency of ANXA1 positive tumors was higher in familial breast cancer patients with BRCA1/2 mutations than in BCAC patients, with 48.6 % versus 12.4 %, respectively; P smaller than 0.0001. ANXA1 was also highly expressed in BCAC tumors that were poorly differentiated, triple negative, EGFR-CK5/6 positive or had developed in patients at a young age. In the first 5 years of follow-up, patients with ANXA1 positive tumors had a worse breast cancer-specific survival (BCSS) than ANXA1 negative (HRadj = 1.35; 95 % CI = 1.05-1.73), but the association weakened after 10 years (HRadj = 1.13; 95 % CI = 0.91-1.40). ANXA1 was a significant independent predictor of survival in HER2+ patients (10-years BCSS: HRadj = 1.
