Revisiting the interaction of heme with hemopexin

In hemolytic disorders, erythrocyte lysis results in massive release of hemoglobin and, subsequently, toxic heme. Hemopexin is the major protective factor against heme toxicity in human blood and currently...

Monitoring Changes in Biochemical and Biomechanical Properties of Collagenous Tissues Using Label-Free and Nondestructive Optical Imaging Techniques

We demonstrate the ability of non-destructive optical imaging techniques such as second-harmonic generation (SHG), two-photon fluorescence (TPF), fluorescence lifetime imaging (FLIM), and Raman spectroscopy...

Vibrational Spectroscopic Investigation of Blood Plasma and Serum by Drop Coating Deposition for Clinical Application

In recent decades, vibrational spectroscopic methods such as Raman and FT-IR spectroscopy are widely applied to investigate plasma and serum samples. These methods are combinedwith drop coating deposition...

The Power in Your Pocket – Uncover Smartphones for Use as Cutting-Edge Microscopic Instruments in Science and Research

Antimicrobial resistance genes in ESBL-producing Escherichia coli isolates from animals in Greece

The prevalence of multidrug resistant, extended spectrum _-lactamase (ESBL)-producing Enterobacteriaceae is increasing worldwide. The present study aimed to provide an overview of the multidrug resistance...

Observing distant objects with a multimode fibre-based holographic endoscope

Holographic wavefront manipulation enables converting hair-thin multimode optical fibers into minimally invasive lensless imaging instruments conveying much higher information densities than conventional...

Surface damage resistance of chemically strengthened silicate glasses: from normal indentation to scratch loading

We report on surface elasticity, plastic deformation and crack initiation of chemically strengthened soda-lime silicate and sodium aluminosilicate glasses during lateral indentation and scratch testing....

Konferenzen und Corona ‐ Routineaufgaben, digitale Kaffeepausen, Chatdiskussionen

In der fortdauernden Covid‐19‐Pandemie versuchen junge Wissenschaftler und Wissenschaftlerinnen, den akademischen Austausch digital aufrechtzuerhalten. Open‐Source‐Programme bieten dabei oft eine...

Leukocyte Activation Profile Assessed by Raman Spectroscopy Helps Diagnosing Infection and Sepsis

OBJECTIVES: Leukocytes are first responders to infection. Their activation state can reveal information about specific host immune response and identify dysregulation in sepsis. This study aims to use...

Higher-order mode supercontinuum generation in dispersion engineered liquid core-fibers

Supercontinuum generation enabled a series of key technologies such as frequency comb sources, ultrashort pulse sources in the ultraviolet or the mid-infrared, as well as broadband light sources for spectroscopic...
