Enhanced Chemo-Immunotherapy Strategy Utilizing Injectable Thermosensitive Hydrogel for The Treatment of Diffuse Peritoneal Metastasis in Advanced Colorectal Cancer.

Patients with colorectal cancer (CRC) and diffuse peritoneal metastasis (PM) are not eligible for surgical intervention. Thus, palliative treatment remains the standard of care in clinical practice. Systemic chemotherapy fails to cause drug accumulation at the lesion sites, while intraperitoneal chemotherapy (IPC) is limited by high clearance rates and associated complications.

Near-infrared light and redox dual-activatable nanosystems for synergistically cascaded cancer phototherapy with reduced skin photosensitization.

Currently, activatable photodynamic therapy (PDT) that is precisely regulated by endogenous or exogenous stimuli to selectively produce cytotoxic reactive oxygen species at the tumor site is urgently in demand. Herein, we fabricated a dual-activatable PDT nanosystem regulated by the redox tumor microenvironment and near-infrared (NIR) light-induced photothermal therapy (PTT). In this study, photosensitizer chlorin e6 (Ce6) was conjugated to hyaluronic acid (HA) via a diselenide bond to form an amphiphilic polymer (HSeC) for loading PTT agent IR780 to produce HSeC/IR nanoparticles (NPs).

Rapid Electrochemical Screening of Phenylketonuria Maker Depending on Dehydrogenase Attached to the Pt-Doped Reduced Graphene Oxide Nanocomposites.

Phenylketonuria (PKU) is a common disease associated with amino acid metabolism, and usually occurs in newborns. It can cause serious neurological diseases and even death. However, owing to inadequate-effective treatment, it can only be slowed by a low-phenylalanine (Phe) diet.

Preparation of Adenosine-Loaded Electrospun Nanofibers and Their Application in Bone Regeneration.

The possibility of composite nanofibers being able to regenerate bone is an attractive proposition. Adenosine, which occurs naturally in humans, has been shown to promote the osteogenic differentiation of mesenchymal stem cells (MSCs) and osteoprogenitor cells. In this study, electrospun nanofibers of poly(3-hydroxybutyrate--3-hydroxybutyrate) (PHBV) doped with adenosine were demonstrated to exhibit excellent capacity for bone regeneration, after optimization of the electrospinning process.

Methotrexate-loaded biodegradable polymeric micelles for lymphoma therapy.

Drug resistance and recurrence are the main clinical challenges in chemotherapy of lymphoma. Methotrexate (MTX), especially high dose MTX (HD MTX), is extensively used to treat some aggressive subtypes of lymphoma, such as Burkitt's lymphoma, in order to overcome drug resistance. But poor solubility of the free drug and severe side effects of HD MTX limit its clinical application.

[Micromeritic evaluation of the direct compression excipient LubriTose AN].

This study is to report the evaluation of the micromeritic properties of LubriTose AN, which is expected to provide preliminary theoretical basis for the direct compression technology. From the aspects of flowability, compressibility and dilution potential, the angle of repose, flow velocity, the Carr' index, tensile strength, elastic recovery, yield pressure and the lubricating ability of LubriTose AN were determined. Also, model drugs were selected to investigate the dilute potential under the desirable compressing performance.
