Scaling Techniques for Exocentric Navigation Interfaces in Multiscale Virtual Environments.

Navigating multiscale virtual environments necessitates an interaction method to travel across different levels of scale (LoS). Prior research has studied various techniques that enable users to seamlessly adjust their scale to navigate between different LoS based on specific user contexts. We introduce a scroll-based scale control method optimized for exocentric navigation, targeted at scenarios where speed and accuracy in continuous scaling are crucial.

Subtype-specific prognostic impact of Bcl-2 in HER2-positive and HER2-negative breast cancer.

Bcl-2, a key regulator of cellular apoptosis, is typically linked to adverse prognosis in solid tumors due to its inhibition of apoptotic cell death and promotion of cellular proliferation, leading to tumor progression. However, studies on Bcl-2 in breast cancer have shown inconsistent results, with some indicating favorable outcomes. This study aims to determine the subtype-specific role of Bcl-2 in breast cancer.

The integrity of thalamo-dorsolateral prefrontal cortex tract: a key factor in residual consciousness in disorders of consciousness patients.

Background: The mesocircuit model describes a complex network that includes the prefrontal cortical-striatopallidal-thalamo-cortical loop systems and is involved in the mechanism underlying consciousness in patients with disorders of consciousness (DoC). Inhibitory signals to the thalamus become hyperactive in DoC patients, leading to a loss of consciousness. Reactivating this mesocircuit system is important for recovering consciousness in these patients.

Surface anatomy and levator scapulae muscle injection: A cadaveric investigation.

Accurate detection of the levator scapulae muscle is critical for effective diagnostic and therapeutic interventions. The commonly used surface anatomy approach has not been validated and is less accurate than ultrasound-guided techniques. Therefore, we determined the needle insertion point for the levator scapulae using a new technique based on the anatomy of the scapula.

Investigating the link between antipsychotic use and post-stroke infections in older people: multi-centre propensity score analysis.

Background: The risk of stroke increases with age, and although previous reports have suggested that infection risk may increase with antipsychotic use, relevant studies after stroke are scarce. We aimed to investigate whether antipsychotics increase post-stroke infection risk in the acute stroke period.

Methods: This propensity score matching study included adults diagnosed with first-ever stroke between 2011 and 2020 at five university hospitals.

Phase Angle as a Marker of Physical Function in Non-Sarcopenic Rheumatoid Arthritis.

: Rheumatoid arthritis (RA) is a chronic autoimmune inflammatory disease. Most patients with RA face a barrier to participation in social activities or exercise due to joint pain, despite the beneficial effects of exercise and physical activity. Thus, RA may be a risk factor for sarcopenia in the clinical field.

Optimal needle electromyography approach to the serratus anterior muscle.

Introduction/aims: There are two conventional needle electromyography (EMG) approaches to the serratus anterior (SA), both of which can result in erroneous insertion into adjacent structures such as the latissimus dorsi (LD), teres major, or external oblique abdominis muscles and pose a risk of long thoracic nerve (LTN) injury. Therefore, we identified a novel needle insertion point for the SA in cadavers that avoids other muscles and LTN injury.

Methods: This study included 17 cadavers: 12 to devise the new method and 5 to verify its accuracy.
