Using molecular dynamics simulations, we study the effect of polyalcohols on water structuring in concentrated solutions, comparing six different polyols that vary in the number of hydroxyl groups and internal structure. For all polyols, we find that the hydrogen bond network order, as assessed by changes in the tetrahedral order parameter, is distorted in the binary solutions as compared with ...
Type 2 diabetes (T2D) generally follows prediabetes (PD) conditions such as impaired fasting glucose (IFG) and/or impaired glucose tolerance (IGT). Although studies reported an association of IGT or IFG with cataract, the experimental basis for PD associated cataract is not known. Hence, we evaluated neonatal streptozotocin (nSTZ) induced rat model to study PD associated cataractogenesis by inj...
Mannitol is one of the primary photosynthetic products and the major phloem-translocated carbohydrate in Olea europaea L., an important crop in the Mediterranean basin. Uptake of mannitol in heterotrophic cell suspensions of O. europaea was shown to be mediated by a 1 : 1 polyol : H+ symport system with a Km of 1.3 mM mannitol and a Vmax of 1.3 nmol min(-1) mg(-1) DW. Dulcitol, sorbitol and xyl...
In recent times, selective hydrogenation of biomass-derived 5-hydroxymethylfurfural (5-HMF) to produce the novel difuranic polyol scaffold 2,5-dihydroxymethylfuran (DHMF) has attracted interest...
Conjugation of methotrexate (MTX) (MW 454) with different molecular weights of polyethylene glycol (PEG) including methoxy-peg (mpeg) 750 D and 5000 D and diol-peg 35000 D led to compounds that are physicochemically highly different from the parent compound, MTX. In this study, an HPLC system consisting of C8 column and UV detector (?=342 nm), using a mixture of 30:70 v/v phosphate-citrate buff...
Background and purpose: Today, due to improvement and progress of human knowledge in food industry, plastic coatings such as PET (polyethylene terephthalate) that has unique characteristics are widely used for food and beverage packaging such as water and doogh. Phthalate esters are used in order to improve flexibility, efficiency and sustainability of materials. Chronic exposure with such mate...
Good footwear should be comfortable, long-lasting and fit for purpose, polyurethanes allow designers to meet all of these objectives. Polyurethanes are used in the industry make insoles shoe soles.There two types PU soles a polyether polyester based sole. Polyether have high resistance against hydrolysis low oil while resistance. In this work thermal mechanical properties elastomers with polols...
An iterative systematic approach to the 1,3-polyol motif has been developed to provide access to all possible stereoisomers by utilizing the catalytic asymmetric Overman esterification for the construction of all stereogenic centres.
We report here a simple route for the chemical synthesis of SmCo5 and Sm2Co17 single-phase and SmCo5/Fe composite nanocrystals by polyol reduction of metal precursors and subsequent calcium reductive annealing. Sm2O3 and Co nanoparticles were synthesized first, and nanocrystalline SmCo5 or Sm2Co17, compound with tunable composition was then obtained after the annealing. The composition of the c...
Commercially used industrial baking enamels consist of alkyd or polyester resin with melamine formaldehyde. These resins are mainly derived from fossil resources. Considering growing environmental legislation regarding use of petroleum based raw materials, utilization of renewable resources to synthesize various chemistries can be the only obvious option as far as academia and industries are co...
