Direct Oral Anticoagulant Use in Atypical Thrombosis-Related Conditions.

Objective: To review the published literature for evidence of the efficacy and safety of direct oral anticoagulants (DOACs) when used in the management of atypical thrombosis-related conditions.

Data Sources: A comprehensive MEDLINE database search (1948 to July 2017) and EMBASE search (1980 to July 2017) were conducted using the search terms direct oral anticoagulant in combination with acute coronary syndrome (ACS), antiphospholipid antibody syndrome (APLAS), and cancer-associated thrombosis (CAT).

Study Selection And Data Extraction: The literature search was limited to studies that were conducted in humans and published in English.

Superhydrophobic and highly luminescent polyfluorene/silica hybrid coatings deposited onto glass and cellulose-based substrates.

Neat poly(9,9-dioctyl-9H-fluorene) (PFO) and composites of PFO and a modified organonanosilica P(7) at weight ratios 90/10, 70/30, and 50/50 have been employed to prepare fluorescent and superhydrophobic coatings by spraying onto three different substrates: glass, Whatman paper, and a filtration membrane of mixed cellulose esters. The water repellency of the coatings and their photophysical properties are therein studied. It is found that, irrespective of the substrate and the composite composition, all coatings remain fluorescent.

Multipurpose ultra and superhydrophobic surfaces based on oligodimethylsiloxane-modified nanosilica.

Nonfluorinated hydrophobic surfaces are of interest for reduced cost, toxicity, and environmental problems. Searching for such surfaces together with versatile processing, A200 silica nanoparticles are modified with an oligodimethylsiloxane and used by themselves or with a polymer matrix. The goal of the surface modification is controlled aggregate size and stable suspensions.

Effect of microstructure on the thermo-oxidation of solid isotactic polypropylene-based polyolefins.

In the present work we aim to clarify the role of the microstructure and the crystalline distribution from the thermo-oxidation of solid isotactic PP (iPP) and ethylene-propylene (EP) copolymers. The effects of the content and quality of the isotacticity interruptions, together with the associated average isotactic length, on the induction time (t) as well as on the activation energy (E) of the thermo-oxidation are analysed. Both parameters have been found to change markedly at an average isotactic length () of 30 propylene units.
