Abstract

Randomly moving but self-propelled agents, such as Escherichia coli bacteria, are expected to fill a volume homogeneously. However, we show that when a population of bacteria is exposed to a microfabricated wall of funnel-shaped openings, the random motion of bacteria through the openings is rectified by tracking (trapping) of the swimming bacteria along the funnel wall. This leads to a buildup of the concentration of swimming cells on the narrow opening side of the funnel wall but no concentration of nonswimming cells. Similarly, we show that a series of such funnel walls functions as a multistage pump and can increase the concentration of motile bacteria exponentially with the number of walls. The funnel wall can be arranged along arbitrary shapes and cause the bacteria to form well-defined patterns. The funnel effect may also have implications on the transport and distribution of motile microorganisms in irregular confined environments, such as porous media, wet soil, or biological tissue, or act as a selection pressure in evolution experiments.

Abstract

Type 2 diabetes (T2D) is associated with several abnormalities in haemostasis predisposing to thrombosis. Moreover, T2D was recently connected with a failure in antiplatelet response to clopidogrel, the most commonly used ADP receptor blocker in clinical practice. Clopidogrel high on-treatment platelet reactivity (HTPR) was repeatedly associated with the risk of ischemic adverse events. Patients with T2D show significantly higher residual platelet reactivity on ADP receptor blocker therapy and are more frequently represented in the group of patients with HTPR. This paper reviews the current knowledge about possible interactions between T2D and ADP receptor blocker therapy.

Abstract

Since their introduction, oral contraceptives have been linked to an increased incidence of thromboembolic events. Epidemiologic studies have shown that women who use third-generation oral contraceptives containing desogestrel, gestodene, or norgestimate have a higher risk of venous thrombosis than women who use second-generation oral contraceptives containing levonorgestrel. Women who use oral contraceptives are significantly less sensitive to activated protein C. From January 1996 to December 2001, 17,577 patients were hospitalized in our department, 177 of them (1%) had confirmed diagnosis of venous thromboembolism and 15 of those (177) were women on oral contraceptive therapy. Oral contraceptives were taken from 28 days to 18 months. No other potential congenital or acquired causes of thrombosis were present before thromboembolic events occurred in these women. The discontinuation of the pill combined with usual heparin (in one patient thrombolysis) and coumarin therapy was effective in all cases. After the discontinuation of coumarin (3-6 months), every patient was screened for hereditary thrombophilia. All women on oral contraceptive therapy had confirmed hereditary risk factors for venous thrombosis. Acquired resistance to activated protein C may explain the epidemiologic observation of increased risk of venous thrombosis in oral contraceptive users, especially in women using third-generation oral contraceptives who had other risk factors (hereditary or acquired) for venous thrombosis.
