Neuroimage Clin 2021 Sep 2;32:102818. Epub 2021 Sep 2.

Department of Neuroscience and Biomedical Engineering, Aalto University School of Science, P.O. Box 12200, 00760 AALTO, Espoo, Finland; Aalto NeuroImaging, Aalto University School of Science, P.O. Box 12200, 00760 AALTO, Espoo, Finland; Department of Neurology, Helsinki University Hospital and Clinical Neurosciences, Neurology, University of Helsinki, P.O. Box 340, 00029 HUS, Helsinki, Finland.

In healthy subjects, motor cortex activity and electromyographic (EMG) signals from contracting contralateral muscle show coherence in the beta (15-30 Hz) range. Corticomuscular coherence (CMC) is considered a sign of functional coupling between muscle and brain. Based on prior studies, CMC is altered in stroke, but functional significance of this finding has remained unclear. Read More

Clinical and radiographic performance of indirect foraminal decompression with anterior retroperitoneal lumbar approach for interbody fusion (ALIF).

Clin Neurol Neurosurg 2021 Sep 16;209:106946. Epub 2021 Sep 16.

IRCCS Istituto Ortopedico Galeazzi, Milan, Italy. Electronic address:

Study Design: Retrospective study BACKGROUND: Indirect decompression with ALIF allows the restoration of the disk and foraminal height with limited soft tissue damage. However, it does not offer a direct view of the neural structure and a direct intraoperative assessment of the results of the decompression is not possible. For this reason, ALIF is often accompanied by posterior, direct decompression. Read More

Suppression of reflected signals from substrate as clutters for cell measurements using acoustic impedance microscopy.

Ultrasonics 2021 Sep 15;118:106580. Epub 2021 Sep 15.

Honda Electronics Co., Ltd, Toyahashi, Aichi 441-3193, Japan.

Recently, a method for estimating three-dimensional acoustic impedance profiles in cultured cells and human dermal organs was proposed by interpreting the reflected ultrasonic signal based on a 1-D transmission line model for acoustic impedance microscopy (AIM). However, AIM has a disadvantage that reflected signals from cells overlap with that from a reference substrate. Additionally, the amplitudes of the reflected signals from the specimens are significantly weaker than that from the substrate. Read More

A limited number of slices yields comparable results to all slices in foot intrinsic muscle deterioration ratio on computed tomography and magnetic resonance imaging.

J Biomech 2021 Sep 13;129:110750. Epub 2021 Sep 13.

Program in Physical Therapy, Washington University School of Medicine in St. Louis, United States. Electronic address:

Diagnostic imaging modalities, like computed tomography (CT) and magnetic resonance imaging (MRI), can be used to assess in vivo muscle quality. Quantitative assessment using these techniques is time-intensive and costly due in part to extensive post-processing needs. The purpose of this study was to identify whether a subset of slices on CT and MRI would yield comparable results to the full number of slices for a measure of muscle quality (muscle deterioration ratio = fat volume/muscle volume) in the foot intrinsic muscles of people with diabetes and peripheral neuropathy.

Hydrophobic and electrostatic interactions modulate protein escape at the ribosomal exit tunnel.

Biophys J 2021 Sep 20. Epub 2021 Sep 20.

Institute of Physics, Vietnam Academy of Science and Technology, 10 Dao Tan, Ba Dinh, Hanoi 11108, Vietnam; Graduate University of Science and Technology, Vietnam Academy of Science and Technology, 18 Hoang Quoc Viet, Cau Giay, Hanoi 11307, Vietnam. Electronic address:

After translation, nascent proteins must escape the ribosomal exit tunnel to attain complete folding to their native states. This escape process also frees up the ribosome tunnel for a new translation job. In this study, we investigate the impacts of energetic interactions between the ribosomal exit tunnel and nascent proteins on the protein escape process by molecular dynamics simulations using partially coarse-grained models which incorporate hydrophobic and electrostatic interactions of the ribosome tunnel of H.
