Determination of Lactic Acid Bacteria Viability in the Small Intestine of Catfish (Pangasius djambal) by Using the 32P Radioisotope

Atom Indonesia, 2015
The viability of probiotics is important to be determined, as is its probiotic potency in the small instestine of fish. The result can be used as a basis to determine the feeding frequency of the probiotics to the fish.The aim of this study is to gain ...

High‐dimensional Spatial Immune Profiling Highlights Microglia‐Like Cells in Human Dorsal Root Ganglia

European Journal of Immunology, Volume 56, Issue 5, May 2026.
High‐dimensional imaging mass cytometry reveals diverse macrophage populations in human dorsal root ganglia (DRG). Microglia‐like cells, characterized by markers such as P2RY12, SLC2A5, and TMEM119, localize near neuronal structures, whereas other myeloid subsets are found in interstitial regions. Spatial analysis reveals distinct localization patterns

Translocation of 32P from leaves to seeds of sunflower and associated biochemical changes in young and mature leaves during seed-filling

Acta Societatis Botanicorum Poloniae, 2014
Transport of 32P from mature leaves was studied at stage I (ray florets opening), stage II (50% florets opening) and stage III (central disc florets opening) of the capitulum in order to ascertain the capacity of developing seeds to draw metabolites ...

Anchoring of Surface Proteins to the Cell Wall of Staphylococcus aureus. III. Lipid II is an in vivo peptidoglycan substrate for sortase-catalyzed surface protein anchoring [PDF]

, 2002
Surface proteins of Staphylococcus aureus are anchored to the cell wall peptidoglycan by a mechanism requiring a C-terminal sorting signal with an LPXTG motif.

A secretory kinase complex regulates extracellular protein phosphorylation. [PDF]

, 2015
Although numerous extracellular phosphoproteins have been identified, the protein kinases within the secretory pathway have only recently been discovered, and their regulation is virtually unexplored.

Telomere Dysfunction and Proteostasis Decline Define Distinct Pathways of Cellular Senescence in the Human Respiratory Tract

Aging Cell, Volume 25, Issue 5, May 2026.
Telomere shortening occurs with age in the respiratory epithelium, but telomere dysfunction‐induced foci (TIF) accumulate only late in life. In contrast, proteostasis decline emerges earlier and correlates with functional impairment, suggesting it may be a primary driver of cellular senescence during physiological aging.

Kinetic characterization of amino acid activation by aminoacyl‐tRNA synthetases using radiolabelled γ‐[32P]ATP

FEBS Open Bio
Aminoacyl‐tRNA synthetases (AARSs) are fundamental enzymes that pair amino acids and tRNAs for protein synthesis. Aminoacylation occurs in two discrete steps.

Oxidized low density lipoprotein-mediated activation of phospholipase D in smooth muscle cells: a possible role in cell proliferation and atherogenesis.

Journal of Lipid Research, 1995
Low density lipoproteins (LDL) are risk factors in atherosclerosis and oxidative modification of LDL to oxidized LDL (OX-LDL) increases its atherogenicity.
