Introduction: Increased demand for consumption of health food with desired sensory properties has led to innovation and new product development in the food industry all over the world. Therefore, the current study aimed to investigate the effect of different concentrations of T. polium oil essential (EO) on chemical and organoleptic properties of Iranian white cheese. Methods: In this study,...
Analytical ultracentrifugation methods were utilized to further characterize the acid denaturation pathways of wild-type, V30M, and L55P transthyretin (TTR) that generate intermediates leading to amyloid fibril formation and possibly the diseases senile systemic amyloidosis and familial amyloid polyneuropathy. Equilibrium and velocity methods were employed herein to characterize the TTR quatern...
Functional diversity based on species traits is a powerful tool to investigate how changes in species richness and composition affect ecosystem functioning. However, studies aimed at understanding changes in functional diversity over large temporal and spatial scales are still scant. Here we evaluate the combined effect of diversification and species sorting on functional diversity of fossil ma...
during recent years several attempts have been made to incorporate environmental and natural resources degradation into national accounts. gnp as measured by the traditional system of national accounts does not consider environmental degradation caused by inefficient exploitation of natural resources. while the complete omission of environmental impacts is not possible, there could be an optima...
Aims & Backgrounds: Alluvial fans are one of the most prominent phenomena in fluvial geomorphology, which are found mostly on the mountain front. These landforms are affected by climate change and tectonic activity and record their effects. Therefore, we can use them to understand climate change and tectonic activities. The aim of this study was to determine the tectonic activity in the northe...
We developed a modified complex of pDNA and poly-l-lysine (PLL) by the addition of poly-l-histidine (PLH) and γ-polyglutamic acid (γ-PGA) to enhance its pH-buffering effect and suppress cytotoxicity. The binary and ternary complexes of pDNA with PLL or/and PLH showed particle sizes of approximately 52-76 nm with cationic surface charge. The ternary complexes showed much higher gene expression t...
