In this study, the rheological properties of three distinct dextrans with different levels (1 → 6)-linked α-D-glucose/(1 3)-linked α-D-glucose units from lactic acid bacteria (LAB) strains were determined. Dextran PDER21 was further selected following measurements and its interactions maize, wheat waxy maize starches determined by characterizing viscoelastic pasting dextran–starch mixtures. Fou...

Membrane fouling, which is a key obstacle in implementing membrane technology, has been studied extensively for aqueous feeds. With increasing interests organic solvent applications, corresponding effort on understanding fouling warranted. This study employs molecular dynamics simulations to unveil the mechanisms underlying different adsorption behaviors of dextran onto polyacrylonitrile (PAN) ...

Ischemic stroke causes the depletion of energy and induces excitotoxicity and neuroinflammation in the brain that results from thrombotic blockage. Cerebral ischemia leads to many types of memory loss, including impairment of working, spatial and object recognition memoreis. Curcumin shows strong anti-oxidoinflammatory activities but it terapathics limited by its low solubility in water and cor...

The functionalization of polysaccharides with synthetic nanopolymers has attracted great attention owing to the applications this method in many industrial fields. This work aimed investigate effect arsenic trioxide on dextran. Dextran-arsenite nanoparticle formation was induced by microwave sulfuric acid as a catalyst. Various analytical techniques were used verify structure nanopolymers. Besi...

the present study was designed to assess the cytotoxicity, anti-inflammatory and analgesic properties of methanol extract of woodfordia fruticosa flowers. cytotoxic activity of methanol extract of woodfordia fruticosa flowers was tested using artemia salina (brine shrimp) bioassay. two doses (400 and 600 mg/kg) were evaluated for the anti-inflammatory activity against the carrageenan, histamine...

The aim of this research was to investigate the effect non-invasive dermal electroporation (EP) on barrier function skin and permeation a model macromolecule in combination with different formulations. Skin samples were treated EP treatment for 2 min. Firstly, examined mouse vivo by measuring transepidermal water loss (TEWL). Then, human investigated ex under fluorescence microscope solution, h...

The first life was believed to emerge in the early Earth via a process involving synthesis of organic compounds and formation protocells. However, it is still puzzle how protocell with hierarchal structure desirable functions spontaneously generated non-living environment composed mainly water minerals. In this work, using muscovite as an example minerals, we systemically studied coacervation p...

to inform healthcare professionals of a rare serious reaction leading to leg amputation following intramuscular injection of iron dextran and report comments for preventing such reactions.a case of leg amputation following intramuscular injection of iron dextran reported to iranian pharmacovigilance center was reviewed. patient and reaction data was collected by assessing the reported yellow ca...
