Motion‐Compensated Diffusion Imaging With Phase‐Contrast for Robust Quantification of Regional Cerebral Blood Flow

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To develop and evaluate a motion‐compensated diffusion imaging with phase‐contrast (MC‐DIP) technique for mitigating errors in regional cerebral blood flow (rCBF) quantification caused by physiological brain motion. Methods Diffusion‐weighted images were acquired in 11 healthy volunteers on a 3.0 T MRI system using three gradient ...

Double Asymmetric Spin Echo EPI (dASE‐EPI) Enables fMRI of the Entire Rat Brain at 9.4 T

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Development and evaluation of a double asymmetric spin echo planar imaging (dASE‐EPI) sequence to balance sensitivity to blood oxygenation level‐dependent (BOLD) contrast with mitigation of susceptibility‐induced intravoxel spin dephasing in ultra high‐field rodent brain imaging.

Uncovering the Genetic Landscape of Spinal Dysraphism: A Retrospective Analysis of 150 Fetal Cases

Prenatal Diagnosis, EarlyView.
ABSTRACT Objective Spinal dysraphism (SD) results from incomplete neural tube closure and encompasses a heterogeneous group of congenital anomalies with genetic and environmental etiologies. Although genetic contributions are recognized, causative variants remain insufficiently defined, and the clinical implications of extended genetic testing on ...

Activatable smart contrast agents for photoacoustic imaging

Smart Molecules, EarlyView.
This review highlights recent advances in smart activatable photoacoustic imaging (PAI) contrast agents, which dynamically modulate their optical properties in response to external stimuli or microenvironmental cues. It discusses their molecular design, activation mechanisms, biomedical applications, and future prospects for clinically tailored use ...

Pseudorandomised controlled trial of a novel navel barrier solution versus 10% iodine to protect navel and ear tag sites of neonatal lambs

Veterinary Record, EarlyView.
Abstract Background During lambing, 10% iodine is often used to protect neonatal navel and ear tag sites. The evidence for its effectiveness is sparse. Recently, a specific navel barrier solution (NBS) was developed. Here, an in vivo field trial compared the two treatments. Methods Ten farms reported data from 6840 lambs. The navel and ear tag sites of

Are we hallucinating or can psychedelic drugs modulate the immune system to control inflammation?

British Journal of Pharmacology, EarlyView.
Psychedelic drugs that activate 5‐HT2A receptors have been long used for cultural, medicinal and recreational purposes. Interest in psychedelics for treating psychiatric disorders has resurged recently and is well documented; less well recognised are their anti‐inflammatory properties. Growing evidence now demonstrates that psychedelics modulate immune

Cerebrovascular Function in Women With Polycystic Ovary Syndrome: A Pilot Multi‐Parameter Magnetic Resonance Imaging Study

Clinical Endocrinology, EarlyView.
ABSTRACT Objective Polycystic ovary syndrome (PCOS) is associated with an increased risk of cerebrovascular disease, but the effects on cerebrovascular function are unknown. In this pilot study, we sought to compare cerebrovascular perfusion, pulsatility, reactivity and metabolism between women with PCOS and healthy volunteers using MRI, and ...

Salivary Proteomic Signatures in Pregnant Women With Excessive Gingival Bleeding

Oral Diseases, EarlyView.
ABSTRACT Objective This observational, cross‐sectional, and analytical study aimed to explore the pathophysiological mechanisms of gingivitis in pregnancy by analyzing the salivary proteomic profile according to gingival bleeding status. Materials and Methods Pregnant women at the 27th week of gestation or beyond were categorized into two groups: those

Far‐infrared irradiation attenuates platelet‐derived growth factor‐stimulated vascular smooth muscle cell migration through protein phosphatase 2A‐mediated Akt inhibition

Photochemistry and Photobiology, EarlyView.
FIR irradiation enhances the physical association between Akt and PP2Ac in VSMCs, independent of the hyperthermal effect of FIR rays. The increased binding between Akt and PP2Ac induced by FIR irradiation facilitates the dephosphorylation of Akt at Ser473.

Spaceborne and spaceborn: Physiological aspects of pregnancy and birth during interplanetary flight

Experimental Physiology, EarlyView.
Abstract Crewed interplanetary return missions that are on the planning horizon will take years, more than enough time for initiation and completion of a pregnancy. Pregnancy is viewed as a sequence of processes – fertilization, blastocyst formation, implantation, gastrulation, placentation, organogenesis, gross morphogenesis, birth and neonatal ...
