poly(vinyl acetate) is synthesized via solution polymerization, and then it is converted to poly(vinyl alcohol) by alkaline alcoholysis. the aim of the work study was to investigate statistically the  influence of reaction variables in vinyl acetate polymerization, the conversion of this monomer to polymer, degree of branching of acetyl group in poly(vinyl acetate), as well as the molecular wei...

Neuropathy is a disease which results in the loss of sensation extremities. One method for assessing degree neuropathy with monofilament evaluator buckles at prescribed force depending on filament diameter. However, as this assessment conducted by clinician's hand, true delivered unknown. Therefore, purpose study was to model effects both insertion depth and diameter contact normal stress produ...

thermodynamic study on the interaction of β-cd with poly ethylene oxide and poly acrylic acid was performed by isothermal titration calorimetry at 298k. when β-cd is added to the interpolymer complex, competition is created between host-guest and hydrogen bond. enthalpy of interaction between the β-cd and interpolymer complex was calculated using the extended solvation theory. p=1 shows that wi...

in this research, hydrogels based on poly vinyl alcohol and poly acrylic acid blend were prepared which were cross-linked by applied thermal conditions. afterward, effects of time and heating on water uptake were investigated. the highest water uptake value exhibited by the sample that was heated for 20 min. at 110 ºc was about 2129% after 4 days at equilibrium state. hydrogels exhibited ph-sen...

Diabetic neuropathy is a common complication of diabetes. While multiple pathways are implicated in the pathophysiology of diabetic neuropathy, there are no specific treatments and no means to predict diabetic neuropathy onset or progression. Here, we identify gene expression signatures related to diabetic neuropathy and develop computational classification models of diabetic neuropathy progres...

PURPOSE/OBJECTIVES To analyze the incidence of chemotherapy-induced neuropathy in a set of patients with gynecologic cancer who were treated with known neurotoxic agents, to identify correlative factors related to patients' experience of neuropathy, and to analyze providers' assessment and treatment of neuropathy. DESIGN Observational descriptive study of patient-reported neuropathy using a r...

OBJECTIVE To describe the sensitivity, specificity, positive predictive value, and negative predictive value of vibration perception threshold (VPT) testing in subjects with type 1 diabetes relative to gold standard assessments of peripheral neuropathy. RESEARCH DESIGN AND METHODS VPT was determined in 1,177 adults with type 1 diabetes 13-14 years after participating in a study of intensive (...

OBJECTIVE To study the nerve conduction velocity in clinically undetectable and detectable peripheral neuropathy in type 2 diabetes mellitus with variable duration. MATERIAL AND METHODS This cross sectional study was conducted in diagnosed type 2 diabetes mellitus patients. They were divided in groups: Group I (n=37) with clinically detectable diabetic peripheral neuropathy of shorter duratio...

the nanocomposites of poly (acryl amide-co-acrylic acid) with different contents of naazeolite were prepared using ammonium persulfate as an initiator and n, n′-methylenebisacrylamide as the crosslinker. the morphology was characterized by sem and the structure ofnanocomposite materials was studied with xrd and ft-ir that showed the interaction betweenporous materials and poly (aam-co-aac). the...
