Chitosan decoration enhanced the thermal and ultraviolet resistance of vitamin A-vitamin D coencapsulated in OSA starch-stabilized emulsion by regulating viscoelasticity, interfacial thickness and structure.

In this study, octenyl succinic acid sodium starch (OSAS) decorated with chitosan (CS) of different molecular weights (50-150 kDa) and concentrations (10-30 mg/mL) was used to stabilize an emulsion coencapsulating with vitamin A (V) and vitamin D (V). The effect of CS decoration on the thermal and UV stability of the emulsion, as well as the underlying mechanism, was elucidated. The incorporation of CS increased the retention rates of V and V by 11.

18F-FDG PET/CT in a Patient With Primary Rectal Angiosarcomas and Multiple Bone Metastases.

A 54-year-old man presented with a 1-month history of pain and numbness in the right lower limb. Lumbar spine MRI revealed bone metastases. 18F-FDG PET/CT showed a soft tissue mass with increased 18F-FDG uptake in the rectum, accompanied by multiple hypermetabolic lesions in the bilateral ribs, spine, pelvis, and upper right femur.

Innovative Ricin Toxin Detection: Unraveling Apurinic/Apyrimidinic Lyase Activity and Developing Fluorescence Sensors.

Ricin toxin (RT) is a potential bioterrorism agent because of its high potency, extremely small lethal dose, ease of preparation, and notable stability. Therefore, a portable method is urgently required to efficiently detect and determine the presence of toxicity of RT and evaluate its potency for public health monitoring and counter-bioterrorism responses. Currently, enzyme-based assays for detecting RT mainly focus on its -glycosidase activity.

10 Years Development of Potassium-Ion Batteries.

Potassium-ion batteries (PIBs), with abundant resources and low cost, are considered as a promising alternative to commercial lithium-ion batteries for low-cost and large-scale applications. Over the past decade, significant academic progresses are made in the development of PIBs, including advancements in cathodes, anodes, and electrolytes. However, most improvements are achieved under laboratory conditions (e.

Enhancement of the nontumor component in newly diagnosed glioblastoma as a more accurate predictor of local recurrence location: a multicenter study.

Background: Although the spatial heterogeneity of glioblastoma (GBM) can be clearly mapped by the habitats generated by magnetic resonance imaging (MRI), the means to accurately predicting the spatial location of local recurrence (SLLR) remains a significant challenge. The aim of this study was to identify the different degrees enhancement of GBM, including the nontumor component and tumor component, and determine their relationship with SLLR.

Methods: A retrospective analysis was performed from three tertiary medical centers, totaling 728 patients with 109 radiation-induced temporal lobe necrosis (TLN) of nasopharyngeal carcinoma (NPC) and 619 with GBM.
