Labeling of penicillamine di sulfide with technetium-99m

, 1998
Complex forming conditions of Penicillamine di sulfide with Tc-99m have been specified. Labeling of penicillamine di sulfide with Tc-99m by direct reduction with SnCl2 did not give favorable good results while the Tc-99m complex of penicillamine can be ...

cGMP Signaling in Arterioles Revealed by FRET‐Based Real‐Time Measurement in Mice In Vivo

Acta Physiologica, Volume 242, Issue 11, November 2026.
ABSTRACT cGMP evokes arteriolar vasorelaxation and is generated in smooth muscle by the soluble guanylyl cyclase (sGC) stimulated by endothelial NO. Phosphodiesterases (PDEs) degrade cGMP and may contribute in diameter regulation. We examined arteriolar cGMP levels in real‐time in vivo upon NO and acetylcholine (ACh) and effects of PDE inhibition ...

Alternatives to the Cox proportional hazards model: A review of additive hazards and accelerated failure time models

Statistica Neerlandica, Volume 80, Issue 4, November 2026.
Abstract The Cox proportional hazards (PH) model remains the dominant approach in survival analysis, but it has two important limitations. First, it relies on the PH assumption, asserting that covariate effects act multiplicatively and remain constant over time.

Preparation of a New Electrochemical Sensor Based on Cadmium Oxide Nanoparticles and Application for Determination of Penicillamine

International Journal of Electrochemical Science, 2011
Novel cadmium oxide nanoparticles based sensor for the detection of penicillamine (PA) in aqueous solution has been developed. Cyclic voltammetry at potential range -1.1 to 1.1V from aqueous buffer solution (pH 7) containing CdO produced a well-defined ...

Is D-penicillamine Safe in Management of Little Children with Kidney Cystine Stones? A Case Series [PDF]

, 2015
Nephrolithiasis is quite common in children. It sometimes has a genetic basis and can lead to serious complications like urinary obstruction, multiple surgical interventions, or even renal insufficiency if left treated.

D -Penicillamine modulates hydrogen sulfide (H2S) pathway through selective inhibition of cystathionine-γ-lyase [PDF]

, 2016
Background and Purpose Hydrogen sulfide (H2S) is a gasotransmitter produced from l-cysteine through the enzymatic action of cystathionine-γ-lyase (CSE) and/or cystathionine-β-synthase.

Comparison of the Cox Proportional Hazards Model and Random Survival Forest Algorithm for Predicting Patient‐Specific Survival Probabilities in Clinical Trial Data

Biometrical Journal, Volume 68, Issue 5, October 2026.
ABSTRACT The Cox proportional hazards model is often used to analyze data from randomized controlled trials (RCTs) with time‐to‐event outcomes. Random survival forest (RSF) is a machine‐learning algorithm known for its high predictive performance. We conduct a comprehensive neutral comparison study to compare the performance of Cox regression and RSF ...

Efficient near‐infrared light‐emitting diodes via enlarging grains of tin‐based perovskites

InfoMat, Volume 8, Issue 10, October 2026.
In this work, penicillamine molecules are introduced into Sn‐based perovskites to slow crystallization, yielding large‐grain films with reduced grain boundaries and passivated defects. The resulting perovskite light‐emitting diodes achieve a maximum external quantum efficiency of 17.5% at 894 nm and an operational half‐lifetime of 0.95 h under current ...
