Synthesis and Stabilization of Support-Free Mesoporous Gold Nanoparticles

open access: yesNanomaterials, 2020
Porous gold nanoparticles (PGNs) are usually prepared in an immobilized form on a solid substrate, which is not practical in many applications. In this work, a simple method is reported for the preparation and stabilization of mesoporous gold particles ...

Versatile Microgel Platform for Intervertebral Disc Degeneration Therapy: Targeting Pericyte‐Mediated Fibrosis and Protecting Nucleus Pulposus Cells

open access: yesAdvanced Science, EarlyView.
The engineered MMS@TRP microgel enables targeted, acid‐responsive delivery of a miR‐21 inhibitor to pericytes. It effectively suppresses disc fibrosis by inhibiting TGF‐β signaling while protecting nucleus pulposus cells via sustained, antioxidant tannic acid release.

Acoustically Activatable Drug‐Loaded Nanodroplets for Mechanochemical Therapy in Solid Tumors

open access: yesAdvanced Science, EarlyView.
Microfluidically fabricated drug‐loaded nanodroplets are sequentially activated by dual‐frequency ultrasound through acoustic droplet vaporization followed by bubble collapse, enabling spatially controlled drug release and mechanical tumor fractionation, resulting in synergistic mechanochemotherapy and prolonged survival.

Polarized IR spectrophotometry of acenaphthene

open access: yes, 2000
Polarized infrared spectrophotometry of acenaphthene and acenaphthene-d10 in stretched polyethylene sheets was used to assign symmetry to vibrational normal modes. B3LYP/6-31G(d) DFT calculations were employed to assist in assignments.

Mitochondrial Protection and Neural Repair via ROS‐Responsive Biomimetic Nanoparticles in Intracerebral Hemorrhage

open access: yesAdvanced Science, EarlyView.
A ROS‐responsive biomimetic nanoparticle platform co‐delivers DIDS and Mdivi‐1 to protect mitochondria and promote neural repair after intracerebral hemorrhage. By targeting LPAR1/VDAC1‐related mitochondrial dysfunction, the nanotherapy reduces oxidative injury, neuronal apoptosis, and blood‐brain barrier disruption, improving neurological recovery and

Infrared fibres in astronomical instrumentation [PDF]

open access: yes, 1995
For several years multi-object spectroscopy systems have been available for carrying out survey work in the visible region, but until very recently there has not been a system for the near infrared region.

Cerebral and Peripheral Tissue Oxygenation in Children Supported on ECMO for Cardio-Respiratory Failure [PDF]

open access: yes, 2009
Extracorporeal membrane oxygenation (ECMO) is a rescue therapy for patients with cardio-respiratory failure. Establishing, maintaining and weaning from ECMO may increase the risk for intracranial injury.

Sonogenetic Control of Engineered Probiotics for the Treatment of MASH by Modulating the Gut‐Liver Axis

open access: yesAdvanced Science, EarlyView.
Researchers developed an engineered probiotic encapsulated in an inulin hydrogel, enabling ultrasound‐triggered intestinal delivery of IL‐22. In MASH model mice, this system remodeled gut microbiota, strengthened the intestinal barrier and reduced portal LPS and hepatic IL‐6.

The effectiveness and utility of near-infrared spectrophotometry for a rapid determination of nutrients in foods [PDF]

open access: yes
We examined the effectiveness of near-infrared spectrophotometry for the nutrient analysis of foods. The energy contents of 18 commercial confectionery products measured by near-infrared spectrophotometry were highly correlated with the values printed on
