Explorative Image Analysis of Methylene Blue Interactions with Gelatin in Polypropylene Nonwoven Fabric Membranes: A Potential Future Tool for the Characterization of the Diffusion Process.

This manuscript explores the interaction between methylene blue dye and gelatin within a membrane using spectroscopy and image analysis. Emphasis is placed on methylene blue's unique properties, specifically its ability to oscillate between two distinct resonance states, each with unique light absorption characteristics. Image analysis serves as a tool for examining dye diffusion and absorption.

[A RARE CLINICAL CASE OF CONGENITAL HYPOPROCONVERTINEMIA].

The paper reports a rare clinical case of congenital hypoproconvertinemia in an elderly woman repeatedly admitted to the Cardiological Department for the management of coronary heart disease and arterial hypertension. The detection of low prothrombin index in a series of analysis requiredfurther hematological examination that revealed the history of postoperative and postnatal hemorrhage along with markedly reduced factor VII level. These results were interpreted as evidence of a rare congenital pathology, hypoproconvertinemia.
