Physiological and artificial solubilizing agents usually enhance apparent solubility of poorly soluble drugs, and in many cases also oral drug exposure. However, exposure may decrease in cases where micellization reduces the molecularly dissolved drug fraction, overriding the solubility advantage. While this information is critical to accurately anticipate the effect of drug micellization on oral absorption, the experimental determination of molecularly dissolved drug concentrations is complex and time consuming.

As it was previously shown, the loss of liver mass affects putative hepatocyte-specific mitogenic inhibitors in the blood. Although the presence of these putative inhibitors regulating precise liver regeneration has been described in numerous publications, they have never been identified.

The platform allows clinicians to interact with 3D patient data through head-mounted displays while remaining sterile. Our workflow converts rotational angiography data to 3D models in real-time, and enables intuitive hand-tracked manipulation of patient data, including tools for cropping, size measurement, and C-arm projection assessment.

- Pediatric idiopathic intracranial hypertension (IIH) is a rare condition with unknown causes, and this study investigated whether increased systemic or cerebral venous pressure might play a role in its development.
- The study involved 11 prepubertal children who underwent various tests, including MRI and pressure monitoring, showing all had elevated venous pressures, but only one had specific venous stenosis while others had normal anatomy.
- The findings suggest that increased systemic venous pressure could be linked to prepubertal IIH, highlighting a need for pediatric-specific diagnostic criteria and further research to understand and treat this condition better.
Article Synopsis
- - The TENSION trial evaluated the long-term safety and effectiveness of endovascular thrombectomy for patients with ischemic stroke and large infarcts, demonstrating favorable outcomes at 90 days, with a follow-up extending to 12 months.
- - Conducted across various hospitals in Europe and Canada, the trial involved patients aged 18 and older with acute ischemic strokes caused by large vessel occlusions, comparing results between those receiving thrombectomy plus medical care versus medical care alone.
- - Out of 253 enrolled patients, results indicated significant insights into functional outcomes, quality of life, and mental health aspects like anxiety and depression, although the trial concluded early due to promising efficacy in the treatment group.
