Authors:
James A Grange

J Psychiatr Res 2022 Jan 7;147:111-125. Epub 2022 Jan 7.

School of Psychology, Dorothy Hodgkin Building, Keele University, Keele, ST5 5BG, United Kingdom. Electronic address:

Successful decision making often requires finding the right balance between the speed and accuracy of responding: Emphasising speed can lead to error-prone performance, yet emphasising accuracy leads to a slowing of performance. Such speed-accuracy tradeoffs (SATs) therefore require establishing appropriate response settings to optimise performance in response to changing environmental demands. Such strategic adaptation of response settings relies on the striatum component of the basal ganglia, an area implicated in depression. Read More

Bone permeability and mechanotransduction: Some current insights into the function of the lacunar-canalicular network.

Tissue Cell 2022 Jan 7;75:101730. Epub 2022 Jan 7.

Institute for Globally Distributed Open Research and Education (IGDORE); Ilmajoki Health Public Dental Clinics, Social and Health Care Services in Jalasjärvi, Ilmajoki, Kurikka, Finland. Electronic address:

Lacunar-canalicular (LC) permeability involves the passage of fluids, nutrients, oxygen, ions, and signalling molecules through bone tissue, facilitating the maintenance of bone vitality and function and responses to various physiological conditions and diseases. LC permeability and fluid flow-shear stress/drag force play important roles in mechanotransduction in bone tissue by inducing mechanical stimuli in osteocytes, modulating cellular functions, and determining bone adaptation. Alterations in LC structure may therefore influence the fluid flow pattern through the LC network, thereby affecting the ability of osteocytes to sense and translate mechanical signals and possibly contributing to bone remodelling.

Quantifying ventilator unloading in CPAP ventilation.

Comput Biol Med 2022 Jan 10;142:105225. Epub 2022 Jan 10.

Department of Intensive Care, Christchurch Hospital, Christchurch, New Zealand.

Background: The intrinsic (muscular) patient effort driving inspiration in non-invasive ventilation modes, such as continuous positive airway pressure (CPAP) therapy, has not been identified from non-invasive data. Current CPAP settings are based on clinical judgment and assessment of symptoms of respiratory distress. Non-optimal settings, including too much positive end expiratory pressure (PEEP) can cause unintended lung injury and ventilator unloading, where patient effort drops and the CPAP device enables too much work being imposed on the injured lung.

Tumour- associated autoantibodies as prognostic cancer biomarkers- a review.

Autoimmun Rev 2022 Jan 12:103041. Epub 2022 Jan 12.

Centre for Precision Health, , Edith Cowan University, Joondalup, Perth, WA, Australia; School of Medical and Health Sciences, Edith Cowan University, Joondalup, Perth, WA, Australia.

Throughout the process of carcinogenesis, autologous cells are transformed into cancer cells, leading to changes in their protein expression profiles. It has been suggested that mutations, protein misfolding, overexpression and aberrant post-translational modifications, changes in protein abundance or location can render tumour-associated antigens immunogenic. Subsequent changes in the tumour microenvironment may lead to humoral immune responses and therefore the production of tumour-associated autoantibodies. Read More

Towards a representative reference for MRI-based human axon radius assessment using light microscopy.

Neuroimage 2022 Jan 12:118906. Epub 2022 Jan 12.

Institute of Systems Neuroscience, University Medical Center Hamburg-Eppendorf, Hamburg, Germany; Department of Neurophysics, Max Planck Institute for Human Cognitive and Brain Sciences, Leipzig, Germany.

Non-invasive assessment of axon radii via MRI bears great potential for clinical and neuroscience research as it is a main determinant of the neuronal conduction velocity. However, there is a lack of representative histological reference data at the scale of the cross-section of MRI voxels for validating the MRI-visible, effective radius (r). Because the current gold standard stems from neuroanatomical studies designed to estimate the bulk-determined arithmetic mean radius (r) on small ensembles of axons, it is unsuited to estimate the tail-weighted r.
