Hybrid Membrane-Coated Nanoparticles for Precise Targeting and Synergistic Therapy in Alzheimer's Disease.

The blood brain barrier (BBB) limits the application of most therapeutic drugs for neurological diseases (NDs). Hybrid cell membrane-coated nanoparticles derived from different cell types can mimic the surface properties and functionalities of the source cells, further enhancing their targeting precision and therapeutic efficacy. Neuroinflammation has been increasingly recognized as a critical factor in the pathogenesis of various NDs, especially Alzheimer's disease (AD).

Microglial Activation, Tau Pathology, and Neurodegeneration Biomarkers Predict Longitudinal Cognitive Decline in Alzheimer's Disease Continuum.

Purpose: Biomarkers used for predicting longitudinal cognitive change in Alzheimer's disease (AD) continuum are still elusive. Tau pathology, neuroinflammation, and neurodegeneration are the leading candidate predictors. We aimed to determine these three aspects of biomarkers in cerebrospinal fluid (CSF) and plasma to predict longitudinal cognition status using Alzheimer's Disease Neuroimaging Initiative (ADNI) cohort.

Preparation and bioavailability of sustained-release doxofylline pellets in beagle dogs.

The objective of this study was to develop doxofylline-loaded sustained-release pellets coated with Eudragit NE30D alone (F1) or blend of Eudragit RL30D/RS30D (F2) and further evaluate their in vitro release and in vivo absorption in beagle dogs. Doxofylline-loaded cores with a drug loading of 70% (w/w) were prepared by layering drug-MCC powder onto seed cores in a centrifugal granulator and then coating them with different kinds of polymethacrylates in a bottom-spray fluidized bed coater. Dissolution behaviour of these formulations was studied in vitro under various pH conditions (from pH 1.

Sheng-mai-san reduces adriamycin-induced cardiomyopathy in rats.

The traditional Chinese medicine prescription "sheng-mai-san (SMS)" has been used for treating patients with coronary heart disease for a long time and was found to have antioxidative effects. Here, we applied adriamycin (doxorubicin, ADR), a highly effective anticancer agent, as an inducer to establish the animal model of dose-related cardiomyopathy due to inhibition of nucleic acid as well as protein synthesis, formation of free radicals, and lipid peroxidation. The objective of this study was to investigate the protective effects of SMS on adriamycin-induced cardiomyopathy.

Panax ginseng reduces adriamycin-induced heart failure in rats.

The purpose of this study was to investigate the protective effects of Panax ginseng on adriamycin-induced heart failure. Wistar rats were divided into four groups: control, adriamycin, ginseng and adriamycin with ginseng. Adriamycin (cumulative dose, 15 mg/kg) was administered to rats in six equal intraperitoneal injections over a period of 2 weeks.

Effects of Xuefu Zhuyu Tang and mitomycin C on liver tumors in mice.

Background: Carcinogenesis, in traditional Chinese medicine, is defined as resulting from the accumulation of stagnant and toxic substances within the human body. Xuefu zhuyu tang (XZT) represents a group of herbs for 'destagnation'; and mitomycin C (MMC) is currently and widely used for cancer therapy. We investigated the combined effects of XZT and MMC on mice bearing liver tumors.
