Men were more likely to be current smokers (P = .02), have a history of hypercholesterolemia (P = .02), and be taking statins (P = .02). Women were more likely to present with critical limb ischemia (P = .03) and had higher median baseline CRP levels (5.15 mg/L; interquartile range [IQR], 1.51-18.62 mg/L) than men (2.70; IQR, 1.24-6.98 mg/L; P = .02). Median follow-up was 893 days (IQR, 539-1315 days). A multivariable Cox proportional hazards model for primary vein graft Selleck 4SC-202 patency showed a significant interaction between sex and CRP (P = .03) and fibrinogen (P = .02). After adjustment

for key covariates, primary vein graft patency was significantly less in women with CRP >5 mg/L compared with women with CRP <5 mg/L (P = .02). No such difference was seen in men (P = .95). Primary graft patency was also decreased in women with fibrinogen >600 mg/dL vs women with fibrinogen <600

mg/dL (P = .002); again, this pattern was not evident in men (P = .19).

Conclusions: Women undergoing LEB for advanced peripheral artery disease have a different inflammatory phenotype selleck compound than men. Elevated baseline levels of CRP and fibrinogen are associated with inferior vein graft patency in women but not in men. These findings indicate an important interaction between sex and inflammation in the healing response of vein grafts for LEB. Women with elevated preoperative CRP and fibrinogen levels may benefit from more intensive postoperative graft surveillance protocols. (J Vasc Surg 212;56:387-95.)”
“Alvinella pompejana is one of the most emblematic species of the animal communities colonizing the deep-sea hydrothermal vents of the East Pacific Rise. This extreme environment is characterized by high temporal variability of its physical chemical parameters. Among these, the variation in concentration of available oxygen

should lead to a specific physiological adaptive response of the animal. To evaluate the mechanisms of this response at a molecular level, a classical 2-DE-based proteomic approach has been implemented. After collection (Garrett-18S ABT-737 and -17S vent sites) animals were reconditioned in a high-pressure chamber pressurized at 260 bar and then the oxygen concentration was regulated to a constant value corresponding to hypoxia, normoxia or hyperoxia for 7 h. The soluble proteins from gills were then analyzed by 2-DE. The protein content of spots showing specific changes following oxygen concentration variation was determined based on comparison of MS/MS sequence data with a recently established A. pompejana ESTs database. Fifteen proteins, belonging mainly to three families, cytoskeleton protein, enzymes of energetic metabolism and heat shock proteins, have been identified as potentially involved in the response to the change in oxygen concentration.
