Vaginal microbicides for the prevention of HIV transmission may be an important option for protecting women from infection. Incorporation of dapivirine, a lead candidate nonnucleoside reverse transcriptase inhibitor, into intravaginal rings (IVRs) for sustained mucosal delivery may increase microbicide product adherence and efficacy compared with conventional vaginal formulations. Twenty-four healthy HIV-negative women 18-35 years of age were randomly assigned (1:1:1) to dapivirine matrix IVR, dapivirine reservoir IVR, or placebo IVR. Dapivirine concentrations were measured in plasma and vaginal fluid samples collected at sequential time points over the 33-day study period (28 days of IVR use, 5 days of follow-up). Safety was assessed by pelvic/colposcopic examinations, clinical laboratory tests, and adverse events. Both IVR types were safe and well tolerated with similar adverse events observed in the placebo and dapivirine groups. Dapivirine from both IVR types was successfully distributed throughout the lower genital tract at concentrations over 4 logs greater than the EC50 against wild-type HIV-1 (LAI) in MT4 cells. Maximum concentration (Cmax) and area under the concentration-time curve (AUC) values were significantly higher with the matrix than reservoir IVR. Mean plasma concentrations of dapivirine were <2 ng/mL. These findings suggest that IVR delivery of microbicides is a viable option meriting further study.

In Week 8, the Bears donned their 1940s throwback uniforms against the Carolina Panthers, who had the worst record in the NFC. The Bears scored first on Matt Forte's 13-yard touchdown run, which would be countered by Justin Medlock's 34-yard field goal. The Panthers then took the lead on Louis Murphy's fumble recovery; Panthers quarterback Cam Newton ran with the ball, and lost the ball when Bears safety Major Wright tackled him at the 1-yard line. The ball rolled into the endzone, where Murphy recovered it. Medlock would then kick three more field goals, and by the fourth quarter, the Panthers led 19-7. The tide eventually turned when Panthers punter Brad Nortman shanked a 6-yard punt, and Jay Cutler hit Kellen Davis on a 12-yard touchdown pass with less than seven minutes left in the game. On the first play of the Panthers' next drive, Tim Jennings intercepted Newton and returned the pick 25 yards to regain the lead 20-19, after Cutler's two-point conversion passing attempt was intercepted. Medlock later kicked another field goal to reclaim the lead 22-20 with 2:27 left in the game. Cutler would lead the Bears downfield, and Gould kicked a 41-yard field goal as time expired to give Chicago the victory. The kick was Gould's tenth game-winning field goal, and the first since 2010.

Reperfusion injury to tissue following an ischemic event occurs as a consequence of an acute inflammatory response that can cause significant morbidity and mortality. Components of both the innate (complement, immunoglobulin, monocytes, and neutrophils) and adaptive (B and T lymphocytes) immune systems have been demonstrated to mediate tissue injury. Spleen tyrosine kinase (Syk) is responsible for membrane-mediated signaling in various cell types including B lymphocytes, macrophages, and T cells. We investigated the ability of a small drug Syk inhibitor, R788, to protect mice against mesenteric ischemia-reperfusion (I/R)-induced local (intestine) and remote lung injury. Mice were fed with chow containing a Syk inhibitor for 6 days before the performance of intestinal I/R, which resulted in silencing of the expression of the active phosphorylated Syk. Syk inhibition significantly suppressed both local and remote lung injury. The beneficial effect was associated with reduced IgM and complement 3 deposition in the tissues and significant reduction of polymorphonuclear cell infiltration. Our data place Syk upstream of events leading to the binding of natural antibodies to the ischemia-conditioned tissues and urge the consideration of the use of Syk inhibitors in the prevention or improvement of tissue injury of organs exposed to ischemia or hypoperfusion.
