  • We investigated the biosynthesis and properties of poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) produced by Haloferax mediterranei from glucose. Size-exclusion chromatography revealed that PHBV produced by H. mediterranei in flask cultures had a weight-average molecular weight of 4.7 × 106 g/mol, demonstrating production of ultrahigh-molecular-weight (UHMW) PHBV. The UHMW-PHBV (7 mol% 3-hydroxyvalerate, Mw = 4.4 × 106 g/mol) obtained by jar fermenter cultivation was used to produce tenfold cold-drawn films with a tensile strength of 258.7 MPa. This suggests that UHMW-PHBV has a potential for practical, strong films.

  • A total of 1074 patients with a history of ischemic stroke enrolled in The Recurrent Stroke Prevention Clinical Outcome (RESPECT) Study were assigned to intensive blood pressure (BP) control group (blood pressure < 120/80 mmHg) or standard blood pressure control group (blood pressure < 140/90 mmHg) and were followed up for a mean of 3.9 years. Seventy-eight first recurrent strokes occurred, including 70 ischemic stroke and 8 intracerebral hemorrhage. Intensive treatment did not change annual risk of ischemic stroke (1.74% vs. 1.75%, P = 0.999), but markedly reduced risk of hemorrhagic stroke (0.00% vs. 0.39%, P = 0.005). Beneficial effect of intensive BP control were observed for risk of hemorrhagic stroke in the patients with a history of ischemic stroke.
