Fluorescence Microscopy [PDF]

Cold Spring Harbor Protocols, 2014
Fluorescence microscopy is a major tool with which to monitor cell physiology. Although the concepts of fluorescence and its optical separation using filters remain similar, microscope design varies with the aim of increasing image contrast and spatial resolution.

Insights into the renal pathophysiology in Hermansky‐Pudlak syndrome‐1 from urinary extracellular vesicle proteomics and a new mouse model

FEBS Letters, Volume 599, Issue 7, Page 1055-1074, April 2025.
Hermansky‐Pudlak syndrome type 1 (HPS‐1) is a rare, autosomal recessive disorder with poorly understood renal involvement. Urinary extracellular vesicle (uEV) proteomics and a novel Hps1 mouse model reveal mitochondrial abnormalities and lipid accumulation in HPS‐1 kidney proximal tubule cells. Serum ApoA1 correlates with kidney function in our patient

Metabolic fingerprinting of bacteria by fluorescence lifetime imaging microscopy

Scientific Reports, 2017
Bacterial populations exhibit a range of metabolic states influenced by their environment, intra- and interspecies interactions. The identification of bacterial metabolic states and transitions between them in their native environment promises to ...

Screening of antioxidant properties of the apple juice using the front-face synchronous fluorescence and chemometrics [PDF]

, 2017
Fluorescence spectroscopy is gaining increasing attention in food analysis due to its higher sensitivity and selectivity as compared to other spectroscopic techniques. Synchronous scanning fluorescence technique is particularly useful in studies of multi-

Residues R177 and S178 of the human Na+/H+ antiporter NHA2 are involved in its inhibition by the flavonoid phloretin

FEBS Letters, Volume 599, Issue 6, Page 901-911, March 2025.
The human Na+/H+ antiporter NHA2 transports Na+ or Li+ in exchange for protons across cell membranes, and its dysfunction results in various pathologies, e.g., fertility disorders, hypertension, or diabetes. This work provides the molecular characterization of interactions of NHA2 with its specific inhibitor phloretin, which can be helpful for the ...

No Difference in Myosin Kinetics and Spatial Distribution of the Lever Arm in the Left and Right Ventricles of Human Hearts

Frontiers in Physiology, 2017
The systemic circulation offers larger resistance to the blood flow than the pulmonary system. Consequently, the left ventricle (LV) must pump blood with more force than the right ventricle (RV). The question arises whether the stronger pumping action of
