Effect of glow discharge plasma on surface modification of chitosan film.

Effect of glow discharge plasma on surface modification of chitosan film. Int J Biol Macromol. 2019 Jul 08;: Authors: Li Y, Wu C, Bai Y, Liu S, Yuan C, Ding T, Hu Y Abstract Glow discharge plasma (GDP) was used to modify chitosan films to obtain desirable properties. The chitosan films were treated with GDP of 0-800 W for 1 min, respectively. The molecular structure of chitosan films changed under GDP treatment. Chitosan films showed an enhancement of crystallinity with the increasing power of GDP, and the GDP treatment provided them with higher thermal stability, manifested as the exothermic peaks shifted from 291.5 °C (0 W) to 294.1 °C (800 W). Scanning electron microscope (SEM) indicated that the surface of chitosan films got rougher with 0-600 W GDP treatment, accompanied by the increase of tensile strength (TS), and the TS did not increase with the 800 W GDP treatment. However, the water vapor permanent (WVP) became higher with GDP treatment. GDP treatment also exhibited influence on chromatic aberration of chitosan films. GDP is proved to be a promising green, pollution-free, rapid technology to modify chitosan films. PMID: 31295495 [PubMed - as supplied by publisher]

CONCLUSIONS: The validity of ICD-10 codes for cirrhosis, oesophageal varices and HCC is high. However, coding for ascites should be combined with a code of chronic liver disease to have an acceptable validity. PMID: 32960654 [PubMed - as supplied by publisher]

Abstract Modification of commercially available Douglas fir biochar (BC) by iron oxide nanoparticle precipitation from aqueous Fe2+/Fe3+ salt solutions upon NaOH treatment generated a hybrid adsorbent (MBC) that removed three common emerging aqueous contaminants, a stimulant (caffeine) and two anti-inflammatory drugs (ibuprofen and acetylsalicylic acid) through batch sorption. Fe3O4 particles (12.3 ± 7.1 nm diameter fundamental particles with aggregates 1-17 μm diameter) dispersed on the biochar surface provided magnetization and created new adsorption sites for the contaminant uptake...

CONCLUSIONS: Although tear substitutes have been historically used to provide eye lubrication to the ocular surface, recent advances in the pathophysiology of dry eye disease (DED) clarified that treatment should not just focus on tear film quality or quantity, but address the loss of homeostasis of the ocular surface, blocking the vicious circle of chronic inflammation and ocular damage. Given the scant comparative evidence on tear substitutes currently on the market, further studies should focus on developing new agents, considering the advantages provided by in vitro models, importance of conducting rigorous clinical tr...

Diseases and disorders such as Parkinson disease, schizophrenia, and chronic pain are characterized by altered mesolimbic dopaminergic neurotransmission. Dopamine release in the nucleus accumbens influences behavior through both tonic and phasic signaling. Tonic dopamine levels are hypothesized to inversely regulate phasic signals through dopamine D2 receptor feedback inhibition. We tested this hypothesis directly in the context of ongoing pain. Tonic and phasic dopamine signals were measured using fast-scan controlled-adsorption voltammetry and fast-scan cyclic voltammetry, respectively, in the nucleus accumbens shell of ...

This study describes our experience with 4 preparatory protocols used in our institution.MethodsFDG PET/CT scans were performed according to 4 preparatory protocols (716 scans total), i.e. 6-h fast (group 1), low-carbohydrate diet plus 12-h fast (group 2), low-carbohydrate diet plus 12-h fast plus intravenous heparin pre-administration (15  IU/kg) (group 3), and low-carbohydrate diet plus 12-h fast plus intravenous heparin pre-administration (50 IU/kg) (group 4). Consecutive scans were retrospectively included from time frames during which the particular protocol was used. FDG uptake in normal myocardium was scor...
