#Bieber + #Blast = #BieberBlast: Early Prediction of Popular Hashtag Compounds [PDF]

open access: yes, 2015
Compounding of natural language units is a very common phenomena. In this paper, we show, for the first time, that Twitter hashtags which, could be considered as correlates of such linguistic units, undergo compounding. We identify reasons for this compounding and propose a prediction model that can identify with 77.07% accuracy if a pair of hashtags ...

Arachidonic Acid as a Possible Negative Feedback Inhibitor of Nicotinic Acetylcholine Receptors on Neurons [PDF]

open access: yes, 1995
Neuronal acetylcholine receptors, being highly permeable to calcium, are likely to regulate calcium-dependent events in neurons. Arachidonic acid is a membrane-permeant second messenger that can be released from membrane phospholipids by phospholipases ...

PIP5K1A Suppresses Ferroptosis and Induces Sorafenib Resistance by Stabilizing NRF2 in Hepatocellular Carcinoma

open access: yesAdvanced Science, EarlyView.
Inducing ferroptosis is a promising strategy for combating tumor resistance. Upregulated PIP5K1A competes with NRF2 for KEAP1 binding, which decreases the ubiquitination degradation of NRF2 and promotes its nuclear translocation, thereby suppressing ferroptosis, and ultimately driving hepatocellular carcinoma (HCC) tumorigeneses and sorafenib ...

Electrocatalytic and voltammetric determination of sulfhydryl compounds through iron nitroprusside modified graphite paste electrode

open access: yesJournal of the Brazilian Chemical Society, 2003
Iron nitroprusside Fe(II)NP was incorporated into a carbon paste electrode and the electrochemical studies were performed with cyclic voltammetry. The cyclic voltammogram of Fe(II)NP exhibits two redox couple with formal potential (E0')1 = 0.24 e (E0')2 =

Near‐Freezing‐Temperature Golgi Neuronal Staining for X‐ray Imaging of Human Brain

open access: yesAdvanced Science, EarlyView.
A near‐freezing temperature staining strategy, combined with a mercury chloride‐based method, effectively preserves delicate neuronal structures in post‐mortem frozen human brain tissues by minimizing autolysis. This approach enables uniform labeling across centimeter‐scale slices and, when integrated with synchrotron‐based X‐ray microscopy, achieves ...

In Situ Electrically Resettable Field‐Effect Transistor Biosensors for Continuous and Multiplexed Neurotransmitter Detection

open access: yesAdvanced Science, EarlyView.
The research team integrated a potentiometrically controlled pH electrode with carbon nanotube (CNT) field‐effect transistor (FET) biosensors on a single chip using compatible processes. By employing zonal modification and optimized pH‐sensitive probes, they achieved simultaneous quadruple‐target detection and tenfold reusability under physiological ...
