Hyperbaric oxygen therapy for sudden sensorineural hearing loss (Review).

Sudden sensorineural hearing loss (SSNHL) is an acute hearing disorder that develops rapidly and is an otolaryngology emergency. Hyperbaric oxygen therapy (HBOT), a non‑pharmacological treatment, has gained increasing attention for SSNHL management. HBOT exerts therapeutic effects by increasing inner ear oxygen partial pressure, improving the microcirculation and reducing inflammation, as its main mechanisms.

Piezo1 disrupts blood-brain barrier via CaMKII/Nrf2 in ischemic stroke.

Ischemic stroke (IS) leads to the disruption of blood-brain barrier (BBB) integrity, resulting in brain edema. In this process, endothelial cells, as a crucial component of the BBB, are subjected to external pressure and tensile stress. Piezo1, a mechanically-sensitive ion channel, may be activated by sensing these stresses, further exacerbating the destruction of the BBB.

Multi-target responsive nanoprobe with cellular-level accuracy for spatiotemporally selective photodynamic therapy.

Photodynamic therapy is known for its non-invasiveness to significantly reduce undesired side effects on patients. However, the infiltration and invasiveness of tumor growth are still beyond the specificity of traditional light-controlled photodynamic therapy (PDT), which lacks cellular-level accuracy to tumor cells, possibly leading to "off-target" damage to healthy tissues such as the skin or immune cells infiltrated. Here, upconversion nanoparticles (UCNPs) were co-encapsulated with manganese dioxide (MnO) by amphiphilic polymers poly(styrene-co-methyl acrylate) (PSMA) and further coated with photosensitizer (riboflavin)-loaded mesoporous silica (C@S/V).

Fate of iron nanoparticles in anammox system: Dissolution, migration and transformation.

Iron nanoparticles (FeNPs) are commonly used in various industrial processes, leading to their release into the environment and eventual entrance into wastewater treatment plants (WWTPs). FeNPs undergo dissolution, migration, and transformation in WWTPs, which can potentially affect the stable operation of anaerobic ammonia oxidation (anammox) systems and may be discharged with wastewater or biomass. To better understand the fate of FeNPs in anammox systems, exposure experiments were conducted using anammox granular sludges (AnGS) and FeNPs.
