We investigated fatty acid synthase expression in patients with renal cell carcinoma and its impact on clinicopathological parameters.
Materials and Methods: Fatty acid synthase expression in 120 patients with renal cancer was examined by immunohistochemistry. The relationship between fatty acid synthase expression status and various clinicopathological parameters was analyzed. Survival analysis was performed using the log rank test and a Cox multivariate hazard model.
Results: Of 120
tumors 18 (15%) showed positive fatty acid synthase expression, which was significantly associated with advanced pathological T stage (pT3-4, p = 0.0009), regional lymph node metastasis (p = 0.0429), distant metastasis (p = 0.0042),
higher histological grade (G3, p = 0.0017) PCI-32765 and microvascular invasion (p = 0.0357). Patients with positive fatty acid synthase expression had significantly shorter cancer specific survival than those with negative FAS expression (p < 0.0001). Multivariate Cox proportional hazards model analysis demonstrated that positive fatty acid synthase expression was an independent predictor of shortened cancer specific survival (p = 0.0363, HR 3.736).
Conclusions: Increased FAS expression could be an indicator of tumor aggressiveness and poor prognosis of renal cell carcinoma. Patients with fatty acid synthase positive tumors should be followed closely and carefully, and adjuvant therapy should be considered.”
“Background: In 1988, the World Health Assembly resolved SRT2104 mw buy Copanlisib to eradicate poliomyelitis. Although substantial progress toward this goal has been made, eradication remains elusive. In 2004, the World Health Organization called for the development of a potentially more immunogenic monovalent type 1 oral poliovirus vaccine.
Methods: We conducted a trial in Egypt to compare the immunogenicity of a newly
licensed monovalent type 1 oral poliovirus vaccine with that of a trivalent oral poliovirus vaccine. Subjects were randomly assigned to receive one dose of monovalent type 1 oral poliovirus vaccine or trivalent oral poliovirus vaccine at birth. Thirty days after birth, a single challenge dose of monovalent type 1 oral poliovirus vaccine was administered in all subjects. Shedding of serotype 1 poliovirus was assessed through day 60.
Results: A total of 530 subjects were enrolled, and 421 fulfilled the study requirements. Thirty days after the study vaccines were administered, the rate of seroconversion to type 1 poliovirus was 55.4% in the monovalent-vaccine group, as compared with 32.1% in the trivalent-vaccine group (P<0.001). Among those with a high reciprocal titer of maternally derived antibodies against type 1 poliovirus (>64), 46.0% of the subjects in the monovalent-vaccine group underwent seroconversion, as compared with 21.3% in the trivalent-vaccine group (P<0.001).
