Concomitant Gradient Effects Across Field Strengths and Gradient Amplitudes: Improved Estimation of Errors and Correction of Concomitant Dephasing and Diffusion Weighting

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Deleterious effects from concomitant gradients are amplified at lower field strengths and stronger gradients. We aimed to show the signal errors caused by concomitant gradients across a wide range of hardware configurations and propose corrections that can be applied during experimental design and analysis.

View Order With Arbitrary Center Echoes

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To provide explicit, vendor‐independent view‐order constructions that enable selection of an arbitrary center echo in multi‐shot imaging, with a focus on RARE and MPRAGE. Methods Vendor‐independent view‐order methods were developed to assign echo and shot indices to a prescribed set of phase encodes, enabling explicit selection of the ...

Multiple Roles of Protamine Kinase SRPK1 and Phosphatase PP1γ in Sperm Development

open access: yesPROTEOMICS, EarlyView.
ABSTRACT Protein phosphorylation regulates key events of male germ cell differentiation. In the testis, SRPK1 and PP1γ are involved in protamine phosphorylation and dephosphorylation, respectively, and their deregulation is linked to defective chromatin structure and male infertility.

x‐Ray Structure of Streptomyces avermitilis Phospholipase D Reveals a Ca2+‐Stabilized Expanded Active‐Site Cleft Adapted for Phospholipid Binding

open access: yesProteins: Structure, Function, and Bioinformatics, EarlyView.
ABSTRACT Phospholipase D (PLD) catalyzes the hydrolysis of phospholipids to generate phosphatidic acid and free head groups such as choline. Among bacterial PLD enzymes, Streptomyces chromofuscus PLD (SchPLD), a member of the alkaline phosphatase D (PhoD) superfamily, exhibits unique Ca2+‐dependent phospholipase activity.
