Auditory stimulus-response modeling with a Match-Mismatch task.

J Neural Eng 2021 Apr 13. Epub 2021 Apr 13.

Danish Research Centre for Magnetic Resonance, Centre for Functional and Diagnostic Imaging and Research, Copenhagen University Hospital, Kettegard Allé 30, Hvidovre, DK-2650, DENMARK.

An auditory stimulus can be related to the brain response that it evokes by a stimulus-response model fit to the data. This offers insight into perceptual processes within the brain and is also of potential use for devices such as Brain Computer Interfaces (BCI). The quality of the model can be quantified by measuring the fit with a regression problem, or by applying it to a classification task and measuring its performance. Read More

Effect of movement speed on lower and upper body biomechanics during sit-to-stand-to-sit transfers: Self-selected speed vs. fast imposed speed.

Hum Mov Sci 2021 Apr 10;77:102797. Epub 2021 Apr 10.

Department of Orthopaedic Surgery, University of Arkansas for Medical Science, Little Rock, AR, USA; Mechanical and Biomedical Engineering Department, Boise State University, Boise, ID, USA.

Preferred and fast speed sit-to-stand and stand-to-sit (STS) tests are prevalent in literature, but biomechanical changes between the different speeds of STS have never been studied. Understanding differences between these STS techniques will better inform experimental design for research assessing functional ability in clinical populations. The purpose of this study was to investigate the effect of different speeds of STS transfers on lower body and trunk kinematics and kinetics in healthy adults. Read More

Olfaction and anosmia: From ancient times to COVID-19.

J Neurol Sci 2021 Apr 3;425:117433. Epub 2021 Apr 3.

Department of Neurology (Nerve-Muscle Unit), University Hospital of Bordeaux (CHU Bordeaux), Pellegrin Hospital, 1 place Amélie Raba-Léon, 33076 Bordeaux, France; Grand Sud-Ouest' National Reference Center for neuromuscular disorders, University Hospital of Bordeaux (CHU Bordeaux), Pellegrin Hospital, 1 place Amélie Raba-Léon, 33076 Bordeaux, France.

Olfaction, one of our five main qualitative sensory abilities, is the action of smelling or the capacity to smell. Olfactory impairment can be a sign of a medical problem, from a benign nasal/sinus problem up to a potentially serious brain injury. However, although clinicians (neurologists or not) usually test the olfactory nerves in specific clinical situations (for example, when a neurodegenerative disorder is suspected), they may omit such tests in many other situations.

A sequence-based prediction of Kruppel-like factors proteins using XGBoost and optimized features.

Gene 2021 Apr 10:145643. Epub 2021 Apr 10.

Faculty of Applied Sciences, Ton Duc Thang University, No.19 Nguyen Huu Tho Street, Tan Hung Ward, District 7, Ho Chi Minh City, Vietnam.

Krüppel-like factors (KLF) refer to a group of conserved zinc finger-containing transcription factors that are involved in various physiological and biological processes, including cell proliferation, differentiation, development, and apoptosis. Some bioinformatics methods such as sequence similarity searches, multiple sequence alignment, phylogenetic reconstruction, and gene synteny analysis have also been proposed to broaden our knowledge of KLF proteins. In this study, we proposed a novel computational approach by using machine learning on features calculated from primary sequences. Read More

Parkinson's disease.

Lancet 2021 Apr 9. Epub 2021 Apr 9.

Institute of Neurogenetics and Department of Neurology, University of Lübeck and University Hospital Schleswig-Holstein, Lübeck, Germany.

Parkinson's disease is a recognisable clinical syndrome with a range of causes and clinical presentations. Parkinson's disease represents a fast-growing neurodegenerative condition; the rising prevalence worldwide resembles the many characteristics typically observed during a pandemic, except for an infectious cause. In most populations, 3-5% of Parkinson's disease is explained by genetic causes linked to known Parkinson's disease genes, thus representing monogenic Parkinson's disease, whereas 90 genetic risk variants collectively explain 16-36% of the heritable risk of non-monogenic Parkinson's disease.

Sustained effect of two antioxidants (oxothiazolidine and δ-tocopheryl glucoside) for immediate and long-term sun protection in a sunscreen emulsion based on their different penetrating properties.

Int J Cosmet Sci 2021 Apr 13. Epub 2021 Apr 13.

Pierre Fabre Dermo-cosmétique, Centre R&D Pierre Fabre, Innovation et Développement Pharmacologie, Avenue Hubert Curien, Cedex 01, 31025, Toulouse, France.

Objective: We investigated the dermal bioavailability and antioxidative properties of a sunscreen formulation containing two antioxidants, oxothiazolidine (OTZ) and δ-tocopheryl glucoside (DTG). OTZ reacts directly with reactive oxygen species to form taurine, while DTG is metabolized in δ-tocopherol to achieve antioxidative activities.

Methods: After topical application to a hair follicle-derived reconstructed human epidermis (RHE) model, followed by solar-simulated radiation, kinetics of bioavailability and antioxidative responses were measured over 24 h. Read More

Multiplexing Mutation Rate Assessment: Determining Pathogenicity of Msh2 Variants in S. cerevisiae.

Genetics 2021 Apr 12. Epub 2021 Apr 12.

Genome Sciences Department, University of Washington, Seattle, WA 98195, USA.

Despite the fundamental importance of mutation rate as a driving force in evolution and disease risk, common methods to assay mutation rate are time consuming and tedious. Established methods such as fluctuation tests and mutation accumulation experiments are low-throughput and often require significant optimization to ensure accuracy. We established a new method to determine the mutation rate of many strains simultaneously by tracking mutation events in a chemostat continuous culture device and applying deep sequencing to link mutations to alleles of a DNA-repair gene.

Serological test performance for bovine tuberculosis in cattle from herds with evidence of on-going infection in Northern Ireland.

PLoS One 2021 13;16(4):e0245655. Epub 2021 Apr 13.

Veterinary Sciences Division, Agri-Food and Biosciences Institute, Stormont, Belfast, Northern Ireland.

The ability to accurately identify infected hosts is the cornerstone of effective disease control and eradication programs. In the case of bovine tuberculosis, accurately identifying infected individual animals has been challenging as all available tests exhibit limited discriminatory ability. Here we assess the utility of two serological tests (IDEXX Mycobacterium bovis Ab test and Enfer multiplex antibody assay) and assess their performance relative to skin test (Single Intradermal Comparative Cervical Tuberculin; SICCT), gamma-interferon (IFNγ) and post-mortem results in a Northern Ireland setting.

Attention-based LSTM for Non-Contact Sleep Stage Classification using IR-UWB radar.

IEEE J Biomed Health Inform 2021 Apr 13;PP. Epub 2021 Apr 13.

Manual scoring of sleep stages from polysomnography (PSG) records is essential to understand the sleep quality and architecture. Since the PSG requires specialized personnel, a lab environment, and uncomfortable sensors, non-contact sleep staging methods based on machine learning techniques have been investigated over the past years. In this study, we propose an attention-based bidirectional long short-term memory (Attention Bi-LSTM) model for automatic sleep stage scoring using an impulse-radio ultra-wideband (IR-UWB) radar which can remotely detect vital signs.

Bleeding and Thrombotic Adverse Events in Hospitalized Patients Under Empiric Treatment for Suspected Heparin-Induced Thrombocytopenia While Awaiting Confirmatory Testing.

Clin Appl Thromb Hemost 2021 Jan-Dec;27:1076029621996473

Hematology, 23217Thomas Jefferson University Hospital, Philadelphia, PA, USA.

Empiric management in suspected heparin-induced thrombocytopenia (HIT) is challenging due to imperfect prediction models, latency while awaiting test results and risks of empiric therapies. When there is high clinical suspicion for HIT, cessation of heparin and empiric non-heparin anticoagulation with FDA-approved argatroban is recommended. Alternatively off-label fondaparinux or watchful waiting have been utilized in clinical practice. Read More
