Pelvimetry by Magnetic Resonance Imaging [PDF]

Obstetrical & Gynecological Survey, 1985
Sagittal and transverse multisection magnetic resonance imaging (MRI) in 10 patients was used to obtain dimensions of the maternal pelvis, determine fetal position, and examine maternal and fetal soft tissues. Dimensions were measured with less than 1% instrument error, and bony landmarks were readily identified.

A nucleotide‐independent, pan‐RAS‐targeted DARPin elicits anti‐tumor activity in a multimodal manner

Molecular Oncology, EarlyView.
We report a Designed Ankyrin Repeat Protein that binds and inhibits RAS proteins, which serve as central cell signaling hubs and are essential for the progression of many cancers. Its unique feature is that it does not discriminate between different RAS isoforms or mutations and is capable of binding to RAS in both its active (GTP‐bound) and inactive ...

Optimizing hip MRI: enhancing image quality and elevating inter-observer consistency using deep learning-powered reconstruction

BMC Medical Imaging
Background Conventional hip joint MRI scans necessitate lengthy scan durations, posing challenges for patient comfort and clinical efficiency. Previously, accelerated imaging techniques were constrained by a trade-off between noise and resolution ...

Cardiovascular magnetic resonance imaging [PDF]

Clinical Cardiology, 2007
Spin-echo imaging is commonly used for assessment of cardiac and great vessel anatomy. With classic spin-echo imaging, rapidly moving blood appears dark. At current field strengths (1.5 and 3.0 tesla), cardiovascular magnetic resonance (CMR) imaging is considered safe for bioprosthetic and mechanical heart valves.

Magnetic resonance imaging of glutamate [PDF]

Nature Medicine, 2012
Glutamate, a major neurotransmitter in the brain, shows a pH- and concentration-dependent chemical exchange saturation transfer effect (GluCEST) between its amine group and bulk water, with potential for in vivo imaging by nuclear magnetic resonance. GluCEST asymmetry is observed ∼3 p.p.m. downfield from bulk water.

Understanding and measuring mechanical signals in the tumor stroma

FEBS Open Bio, EarlyView.
This review discusses cancer‐associated fibroblast subtypes and their functions, particularly in relation to extracellular matrix production, as well as the development of 3D models to study tumor stroma mechanics in vitro. Several quantitative techniques to measure tissue mechanical properties are also described, to emphasize the diagnostic and ...

The structural and functional brain alternations in tobacco use disorder: a systematic review and meta-analysis

Frontiers in Psychiatry
BackgroundWhile numerous previous studies have indicated that nicotine intake results in gray matter and functional brain abnormalities in tobacco use disorder (TUD), the majority of results could not be replicated or even reversed.

The Protective Roles of Urinary Trypsin Inhibitor in Brain Injury Following Fat Embolism Syndrome in a Rat Model

Cell Transplantation, 2019
Fat embolism syndrome (FES) is a common complication following long bone fracture; fat droplets are released into the blood circulation and form embolisms, mainly in lung and brain. However, the potential mechanisms involved remain to be clarified.
