Plasma Pharmacokinetic Profile of Fipronil 1% Pour‐On in Cattle: Photodegradation and the Sustained Systemic Persistence of Fipronil Sulfone

Journal of Veterinary Pharmacology and Therapeutics, EarlyView.
ABSTRACT This study characterized the long‐term pharmacokinetic profile of a 1% fipronil pour‐on formulation in Nellore bulls under field conditions. Seventeen animals received a single topical dose (1 mg/kg), and plasma concentrations of fipronil and its metabolites (sulfone and desulfinyl) were monitored for 175 days using LC–MS/MS.

Electrical penetration graph (EPG) results.

, 2013
EPG recording with each aphid was conducted for 8 h. Values are means ± SE of EPG parameters. Mann-Whitney U tests were used to determine the significant difference between the activities of aphids on the mutant and the wild type plants.

Signal and Contrast Optimization With Predicted Excitations (SCOPE) for Accelerating Large FOV Body Imaging at UHF

Magnetic Resonance in Medicine, Volume 96, Issue 2, Page 635-649, August 2026.
ABSTRACT Purpose Large FOV turbo‐spin‐echo (TSE) imaging at ultra‐high field (UHF) remains challenging due to B1+ inhomogeneity and peak specific absorption rate (pSAR) limitations. This work presents a new time‐interleaved acquisition of modes (TIAMO) framework called SCOPE (Signal and Contrast Optimization with Predicted Excitations), which overcomes

Clique coloring B1-EPG graphs [PDF]

, 2020
We consider the problem of clique coloring, that is, coloring the vertices of a given graph such that no (maximal) clique of size at least two is monocolored. It is known that interval graphs are 2-clique colorable.

Consistent Quadratic Phase Formation in 3D Fast Spin Echo Using Frequency‐Modulated RF Pulses

Magnetic Resonance in Medicine, Volume 96, Issue 2, Page 666-681, August 2026.
ABSTRACT Purpose Frequency‐modulated (FM) RF pulses achieve broadband excitation with low RF peak power, which is required in MRI with inhomogeneous magnetic fields. However, the quadratic phase generated with FM pulses makes it difficult to use them in fast spin echo (FSE), because even and odd refocused echoes have different spatial phase profiles ...

Optimizing Selective RF Pulses for Enhanced Signal Stability in Turbo Spin Echo Using a Differentiable Extended Phase Graph Model

Magnetic Resonance in Medicine, Volume 96, Issue 1, Page 214-226, July 2026.
ABSTRACT Purpose To improve slice profile consistency across echo trains in turbo spin echo (TSE) imaging, thereby reducing image blurring and increasing the accuracy of multi echo spin echo T2$$ {T}_2 $$ mapping. Methods Excitation and refocusing RF pulses were optimized for TSE using a differentiable extended phase graph model that incorporates the ...

Multiparametric Free‐Breathing 3D Whole‐Heart Cardiac MR for Anatomical Bright‐ and Black‐Blood Imaging With Co‐Registered T1/T2$$ {T}_1/{T}_2 $$ Myocardial Tissue Mapping at 0.55$$ 0.55 $$ T

NMR in Biomedicine, Volume 39, Issue 7, July 2026.
Novel 3D CMR free‐breathing whole‐heart sequence demonstrated the feasibility of high‐resolution coronary angiography and simultaneous bright‐ and black‐blood imaging, together with joint T1/T2$$ {T}_1/{T}_2 $$ mapping despite the inherent limitations of low‐field strength at 0.55 T, suggesting its potential for comprehensive cardiac assessment in ...
