Intrinsic clearances of seven diverse compounds in rat liver microsomes were measured at intracellular pH 7.0 and extracellular pH 7.4. The obtained values were quite close for each compound. These results confirm the validity of the recently published novel equations for calculation of hepatic clearance and drug time course in liver that account for pH differences in extracellular water and hepatocytes.

Background: Cancer patients have up to a 3-fold higher risk for cardiovascular disease (CVD) than the general population. Traditional CVD risk scores may be less accurate for them. We aimed to develop cancer-specific CVD risk scores and compare them with conventional scores in predicting 10-year CVD risk for patients with breast cancer (BC), colorectal cancer (CRC), or lung cancer (LC).

Objective: Spinopelvic sagittal balance ensures efficient posture and minimizes energy expenditure by aligning the spine, pelvis, and lower extremities. Deviations can cause clinical issues like back pain and functional limitations. Key radiographic parameters, including pelvic tilt (PT), pelvic incidence (PI), sacral slope (SS), and lumbar lordosis (LL), are essential for evaluating spinal pathologies and planning surgeries.

Shifting surface plasmon resonance wavelength to the far-ultraviolet region with aluminum-based sensors.

A novel aluminum (Al)-based surface plasmon resonance (SPR) sensor operating in the far-ultraviolet (FUV, <200 nm) region has been developed. By utilizing a thinner Al film compared to previously reported deep-ultraviolet (DUV, <300 nm) SPR sensors, the SPR wavelength was effectively maintained within the FUV region across various liquids. In the presence of resonant molecules, the SPR wavelength shift was notably enhanced.

Background: Stereotactic radiosurgery (SRS) is widely used for managing brain metastases (BMs), but an adverse effect, radionecrosis, complicates post-SRS management. Differentiating radionecrosis from tumor recurrence non-invasively remains a major clinical challenge, as conventional imaging techniques often necessitate surgical biopsy for accurate diagnosis. Machine learning and deep learning models have shown potential in distinguishing radionecrosis from tumor recurrence.

Fire safety in healthcare facilities is extremely important due to limited evacuation capacity of occupants. Therefore, poor fire safety precautions lead to more fatalities and financial losses. This study introduces an effective fire risk management approach for healthcare buildings utilizing an interval valued neutrosophic-fuzzy framework.
