background some herbal anticancer agents have direct interactions with dna. objectives the present study aimed to investigate the interaction of ctdna with rosemary flowers. materials and methods we used uv-vis, fluorescence and circular dichroism (cd) spectroscopic techniques. results the absorption of dna at 260 nm increased on addition of rosemary. herb extract quench the fluorescence of etb...

Curcumin (CUR) is the active curcuminoid with many physiological, biochemical, and pharmacological properties. Solubility and stability of CUR is the limiting factors for realizing its therapeutic potential. Bovine β-casein is an abundant milk protein that is highly amphiphilic and self-assembles into stable micellar nanoparticles in aqueous solution. β-Casein nanoparticle can solubilize CUR mo...

Macromolecules drive the complex behavior of neurons. For example, channels and transporters control the movements of ions across membranes, SNAREs direct the fusion of vesicles at the synapse, and motors move cargo throughout the cell. Understanding the structure, assembly, and conformational movements of these and other neuronal proteins is essential to understanding the brain. Developments i...

perrault's syndrome (p.s.) is rare. the combination of gonadal dysgenesis and hearing loss was accompanied by 46,xxkaryotype in three sisters with parental consanguineous marriage. genetic investigation revealed normal female karyotype, positive liarr and negative fluorescence ipj-bodies, which was confirmed by molecular study on the basis of fluorescence in situ hybridization (pish), with appl...

Fluorescence microscopy images of red blood cells at different temperatures (different stiffness) incubated in a DASPI molecular rotor solution.

Pyridine appended structural isomers showed a planar or propeller conformation dependent molecular self-assembly, fluorescent polymorphs, stimuli-responsive fluorescence switching and halochromism.

UV-visible and Fluorescence spectroscopic methods were employed to study the interaction of human serum albumin (HSA) with Valacyclovir Hydrochloride. Additionally, molecular dynamics and molecular docking simulations were used to visualize and specify the binding site of Valacyclovir Hydrochloride. The Stern-Volmer and van't Hoff equations along with spectroscopic observations, were used to de...

A class of reactive DNA circuits was adapted as erasable molecular imaging probes that allow fluorescent reporting complexes to be assembled and disassembled on a biological specimen. Circuit reactions are sequence-dependent and therefore facilitate multiplexed (multicolor) detection. Yet, the ability to disassemble reporting complexes also allows fluorophores to be removed and new circuit comp...
