Chitosan-based hydrogels are prepared via the formation of polypseudorotaxanes (PPR), by selectively threading α-cyclodextrin (α-CD) macrocycles onto polymeric chains, which, through microcrystalline domains, act as junction points for network. Specifically, host–guest inclusion complexes formed between α-CD and PEGylated chitosan (PEG-Ch), resulting in supramolecular gels. PEG-grafted is obtai...

Binding of lambda carrageenan (lCG) to bovine serum albumin (BSA) and the effect formation path, namely mixing (M) at specific pH versus titration (T) from a neutral mixture, on complexation have been studied using turbidimetry, phase analysis, dynamic light scattering, confocal laser scanning bright-field optical microscopy, circular dichroism fluorescence measurements. The sizes shape complex...

Studies have been made of the factors affecting the specificity of the interaction between high molecular weight dextran sulphate and low-density lipoproteins, both in pure solution and in serum. The results have been used in the development of a simple assay method for the serum concentration of low-density lipoproteins in small volumes of serum. The results obtained by this assay procedure ha...

We tested the hypothesis that fibrin structure/function is unfavorably altered in patients after idiopathic venous thromboembolism (VTE) and their relatives. Ex vivo plasma fibrin clot permeability, turbidimetry, and efficiency of fibrinolysis were investigated in 100 patients with first-ever VTE, including 34 with pulmonary embolism (PE), 100 first-degree relatives, and 100 asymptomatic contro...

Dynamic light scattering, static light scattering, and turbidimetry were used to investigate the effect of polyelectrolyte molecular weight and concentration on complex formation between a strong polyelectrolyte, poly(dimethyldially1ammonium chloride) (PDMDAAC), and oppositely charged mixed micelles of Triton X-100 (TX100) and sodium dodecyl sulfate (SDS). The hydrodynamic radius (Rh) of the co...

UNLABELLED Since the beginning of their lives, all living organisms are exposed to the influence of geomagnetic fields. OBJECTIVES With respect to the positive effects that magnetic fields have on human tissues, especially the bactericidal effect, this investigation aimed to assess their influence on the reduction of oral microorganisms. MATERIAL AND METHODS In order to obtain adequate spec...

The objective of this work is to verifying the consume of the minerals K, Na, Fe, Mg, P, S-SO4 (-2), B, N Total Kjedahl (NTK), NO3 (-)-N, and NH4 (+)-N in the production of bacterial cellulose by Acetobacter xylinum, according to the medium and the manner of cultivation. The fermentative process was in ripe and green coconut water. K and Na were determined by flame emission photometry, Mg and F...

Objective To evaluate the usefulness of biomarkers to predict evolution patients suspected systemic lupus erythematosus (SLE), designated as probable SLE (pSLE), into classifiable according American College Rheumatology (ACR) classification criteria. Methods Patients were enrolled by experts if they fulfilled three ACR criteria for and followed approximately 1-3 years transition ACR-classifiabl...
