Oral solid lipid nanoparticles of etoposide enable metronomic-like therapy with reduced toxicity in MYCN-amplified neuroblastoma Therapeutic regimens for pediatric malignancies such as neuroblastoma remain complex and are often associated with severe systemic toxicity. The devel…

What if oral etoposide could work better in a neuroblastoma with less toxicity?

New paper: oral solid lipid nanoparticles improved bioavailability, and slowed tumor growth.
The team used HypoxyLab + OxyLite to create and verify stable hypoxia in vitro.

Performance of Wearable Pulse Oximetry During Controlled Hypoxia Induction: Instrument Validation Study Background: Oxygen saturation is a crucial metric used for monitoring patients with lung disease or respiratory illness who are at risk of hypoxemia (low blood oxygen saturation). Early and accurate identification of abnormal oxygen saturation is important for these patients, who may develop significant desaturation and hypoxemia symptoms during their daily activities. Objective: This study aimed to evaluate the accuracy of Apple Watch Series 7 and a clinical-grade pulse oximeter, Masimo MightySat Rx, under hypoxemia and to assess whether measurement error is influenced by the oxygen desaturation rate (ODR). Methods: We calculated the ODR of each measurement and conducted a comparative analysis of the displayed oxygen saturation readings from both the Masimo MightySat Rx finger pulse oximeter and Apple Watch Series 7 with arterial blood oxygen saturation (SaO) readings obtained from a blood gas analyzer. Results: Both the Masimo MightySat Rx pulse oximeter and the Apple Watch Series 7 tended to overestimate oxygen saturation. The pulse oximeter readings were more likely to fall within 2% of the acceptable (as specified by Masimo) peripheral oxygen saturation (SpO) error range than the Apple Watch (49.03% vs 32.14%). Notably, both devices had limitations under low oxygen saturation levels (

What is the Difference Between Dissolved Oxygen and Oxygen Saturation? Differences between dissolved oxygen and oxygen saturation in tissue contexts, and why the OxyLite by Oxford Optronix measures dissolved oxygen (tissue pO₂) for precise, real-time oxygen monitoring at...

Dissolved oxygen is not the same as oxygen saturation. One reflects the oxygen actually available locally to cells. The other reflects how full hemoglobin is.

That is why OxyLite measures tissue pO₂ directly, giving a clearer view of local oxygen biology.

Two weeks after infection, lung #TLS could be divided into inner and outer zones based on B cell proportional density. The outer zone was enriched for non-GC Tfh signatures and HIF-1α–associated pathways, such as #Hypoxia, also observed by Hypoxyprobe staining (2/10).
