Potential for reduction of radiation dose in the assessment of the lead orientation in directional deep brain stimulation electrodes.

Purpose: Directional deep brain stimulation (dDBS) relies on electrodes steering the stimulation field in a specific direction. Post implantation, however, the intended and real orientation of the lead frequently deviates e.g.

Mild-to-moderate hip osteoarthritis and hip bracing influence hip and knee biomechanics during 90° turns while walking.

Background: Turning movements are frequently encountered during daily life and require more frontal and transverse hip mobility than straight walking. Thus, analysis of turning might be an insightful addition in the evaluation of conservative treatment approaches for hip osteoarthritis patients. The study objective was to quantify the effects of mild-to-moderate symptomatic hip osteoarthritis on lower-body turning biomechanics and evaluate the effects of hip bracing in this cohort.

Human motor performance assessment with lower limb exoskeletons as a potential strategy to support healthy aging-a perspective article.

With increasing age, motor performance declines. This decline is associated with less favorable health outcomes such as impaired activities of daily living, reduced quality of life, or increased mortality. Through regular assessment of motor performance, changes over time can be monitored, and targeted therapeutic programs and interventions may be informed.

Does Bisphenol A (BPA) Exposure Cause Human Diseases?

Background: Autism spectrum disorders (ASDs), attention-deficit disorder (ADHD), Parkinson's disease (PD), polycystic ovary disease (PCOS), and Alzheimer's disease (AD) have all been linked to exposure to bisphenol A (BPA).

Methods: This paper is a review and discussion of the published literature.

Results: Animal studies have shown BPA to be a broad-spectrum endocrine disruptor.

Photochemical pathways in astronomical ices: A computational study of singlet oxygen reactions with hydrocarbons.

Complex organic molecules are widespread in different areas of the interstellar medium, including cold areas, such as molecular clouds, where chemical reactions occur in ice. Among the observed molecules are oxygen-bearing organic molecules, which are of high interest given their significant role in astrobiology. Despite the observed rich chemistry, the underlying molecular mechanisms responsible for molecular formation in such cold dilute areas are still not fully understood.
