FEBS Letters, EarlyView.Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation
FEBS Letters, EarlyView.Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

New Journal of Physics, 2015 Fast frame rate complementary metal–oxide–semiconductor cameras in combination with photon counting image intensifiers can be used for microsecond resolution wide-field fluorescence lifetime imaging with single photon sensitivity, but the time resolution

FEBS Letters, EarlyView.The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...

Halation in image intensifiers [PDF]
Monthly Notices of the Royal Astronomical Society, 1992 Halation effects in microchannel plate intensifiers are discussed. It is shown that infilling of line profiles observed in absorption-line spectra taken with four-stage magnetically focused intensifiers cannot be explained by such a mechanism; it is suggested that slow phosphor decay may instead be a cause of the ...

FEBS Letters, EarlyView.We identified a systemic, progressive loss of protein S‐glutathionylation—detected by nonreducing western blotting—alongside dysregulation of glutathione‐cycle enzymes in both neuronal and peripheral tissues of Taiwanese SMA mice. These alterations were partially rescued by SMN antisense oligonucleotide therapy, revealing persistent redox imbalance as ...

Repositioning of Misplaced Central Venous Catheter with Saline Injection Under C-Arm Imaging [PDF]
Journal of Clinical and Diagnostic Research, 2015 Malposition of central venous catheter is a well known technical complication. Misplaced catheter often requires reinsertion for proper placement of the catheter in the superior vena cava (SVC) to support safe delivery of care and minimize ...

FEBS Letters, EarlyView.In this study, we found that human cervical‐derived adipocytes maintain intracellular iron level by regulating the expression of iron transport‐related proteins during adrenergic stimulation. Melanotransferrin is predicted to interact with transferrin receptor 1 based on in silico analysis.

Point Spread Function Estimation of Image Intensifier Tubes
, 1992 Real-time radiography systems employing an image intensifier tube have poor resolution (2 to 4 Ip/mm) compared to their film-based counterparts (10 to 20Ip/mm).
