The Uptake of 32P by Brown Planthoppers (Nilaparvata Lugens Stal) Gonads

open access: yesJournal of Mathematical and Fundamental Sciences, 2019
. The radioisotop 32P has been used quite extensively in the field of insect ecology and insect physiology. It has been widely known that 32P is one of the several isotopes applied to tag the insects for migration studies, to estimate the sap uptake or ...

The specificities of small molecule inhibitors of the TGF beta and BMP pathways [PDF]

open access: yes, 2011
Small molecule inhibitors of type 1 receptor serine threonine kinases (ALKs1-7), the mediators of TGF beta and BMP signals, have been employed extensively to assess their physiological roles in cells and organisms. While all of these inhibitors have been

Stimulation by serum of 32P incorporation into the phospholipids of Ehrlich ascites cells

open access: yesJournal of Lipid Research, 1977
Ehrlich ascites cells adapted for suspension culture were incubated with 32PO43- in a Krebs-Ringer-HEPES (N-2-hydroxyethyl-piperazine-N'-2-ethanesulfonate) buffer with or without 5% calf serum.

Interference fragmentation functions in electron-positron annihilation [PDF]

open access: yes, 2003
We study the process of electron-positron annihilation into back-to-back jets, where in each jet a pair of hadrons is detected. The orientation of these two pairs with respect to each other can be used to extract the interference fragmentation functions ...

Alternatives to NIST Cf-252 Iirradiations for Transfer Calibration of S-32 Neutron Monitors [PDF]

open access: yesEPJ Web of Conferences
Gas-flow proportional counting systems are used by the Radiation Metrology Laboratory (RML) at Sandia National Laboratories for reactor fluence monitoring with the 32S(n,p)32P reaction.

Protein associated with SMAD1 (PAWS1/FAM83G) is a substrate for type I bone morphogenetic protein receptors and modulates bone morphogenetic protein signalling [PDF]

open access: yes, 2014
Bone morphogenetic proteins (BMPs) control multiple cellular processes in embryos and adult tissues. BMPs signal through the activation of type I BMP receptor kinases, which then phosphorylate SMADs 1/5/8.

Mitochondrial CircRNA CircMT‐RNR2 Safeguards Antioxidant Defense to Support Fibroblast Functions in Wound Repair

open access: yesAdvanced Science, Volume 13, Issue 26, 8 May 2026.
CircMT‐RNR2 promotes wound healing by enhancing fibroblast proliferation, migration, contraction, and extracellular matrix (ECM) production. It sustains mitochondrial redox balance by stabilizing the antioxidant protein PRDX3, thereby reducing ROS‐induced damage. In diabetic foot ulcers, hypoxia, hyperglycemia, and reduced FGF2 and EGF expression lower
