Intranasal delivery of mesenchymal stem cell-derived exosomes ameliorates experimental autoimmune encephalomyelitis.

Background: Exosomes derived from bone marrow mesenchymal stem cells (BMSCs-Exos) have shown therapeutic potential in experimental autoimmune encephalomyelitis (EAE). As a non-invasive method of drug administration, intranasal delivery is anticipated to emerge as a novel option for the treatment of central nervous system (CNS) disorders. Therefore, this study aims to treat EAE by nasal exosomes and explore its specific mechanism, especially its impact on the blood-brain barrier (BBB).

Recent advancements in traditional Chinese medicine for COVID-19 with comorbidities across various systems: a scoping review.

Background: Traditional Chinese medicine (TCM) has developed a rich theoretical system and practical experience in fighting to infectious diseases over the past thousands of years, and has played an important role in controlling the spread owing to its unique advantages. In particular, its significant contribution to the prevention and control of Corona Virus Disease 2019 (COVID-19) is widely recognized. COVID-19 infection is mainly non-severe with a favorable overall outcome, but patients with comorbidities tend to have a poor prognosis.

Temporal, spatial and demographic distributions characteristics of COVID-19 symptom clusters from chinese medicine perspective: a systematic cross-sectional study in China from 2019 to 2023.

Background: The subtypes diagnosis of disease symptom clusters, grounded in the theory of "Treatment in Accordance with Three Categories of Etiologic Factors" and International Classification of Diseases 11th Revision (ICD-11), is a vital strategy for Chinese Medicine (CM) in treating unknown respiratory infectious diseases. However, the classification of disease symptom clusters continues to depend on empirical observations and lacks robust scientific evidence. Consequently, this study seeks to explore the temporal, spatial and demographic distributions characteristics of Corona Virus Disease 2019 (COVID-19) symptom clusters in China.

Taxonomic, phylogenetic, and functional nestedness of mammal assemblages in the Zhoushan Archipelago, China.

Nestedness is an important part of the theoretical framework of island biogeography and community ecology.

Prenatal high-sucrose diet affects pulmonary artery contractile functions via MT receptors.

A high sucrose diet during pregnancy may generate profound effects on vascular diseases in offspring later in life. Pulmonary artery (PA) functions is closely related to pulmonary hypertension, but whether and how prenatal high-sucrose diet (HS) affect pulmonary vasoreactivity in adult offspring remains unknown. We investigated the alterations of PA reactivity in postnatal offspring exposed to prenatal HS.

Identification of QTL-allele systems of seed size and oil content for simultaneous genomic improvement in Northeast China soybeans.

Northeast China (NEC) is the major production area for soybeans in China, whereas its soybean germplasm has played key roles in world soybean production, especially in the Americas.

Detecting telomerase activity at the single-cell level using a CRISPR-Cas12a-based chip.

The intimate association between telomerase activity and cancer has driven the exploration of diverse methodologies for its precise detection. However, detecting telomerase activity at the single-cell level remains a significant challenge. Herein, we present a MOF-DNA barcode-amplified CRISPR-Cas12a strategy integrated with a single-cell microfluidic chip for ultrasensitive detection of telomerase activity.

Correlation between pre-operative VE-cadherin and DLL4 and the maturation after primary arteriovenous fistula in uremic patients.

Aims: Uremic patients require dialysis to replace the declined kidney function, and arteriovenous fistula (AVF) is a commonly used dialysis access route. Our study aimed to explore vascular endothelial cells cadherin (VE-cadherin) and Delta-like ligand 4 (DLL4) expression in uremic patients undergoing primary AVF surgery and their correlation with AVF maturation.

Methods: We conducted a prospective study that included = 55 voluntary uremic patients receiving their initial AVF procedure for renal replacement therapy, subjects were divided into a mature group and a failure group based on whether the AVF matured within 3 months post-operatively.

Synthesis and Biomedical Applications of Covalent Organic Frameworks for Disease Diagnosis and Therapy.

Covalent organic frameworks (COFs) have emerged as a distinguished class of porous materials. Owing to their ability to be constructed through covalent bonds involving light elements, such as hydrogen, boron, carbon, nitrogen, and oxygen, COFs offer greater stability and lower cytotoxicity than metal-organic frameworks do, addressing critical limitations in in vivo applications. Their unique attributes, such as high surface area, customizable pore sizes, and versatile surface functionalities, make them ideal for various biomedical applications.

Cellulose nanocrystals (CNCs) with different degrees of amination to enhance tolerance to Fe (III) and enhance oil displacement performance.

Cellulose nanocrystals (CNCs) have been widely concerned in enhanced oil recovery (EOR) due to their abundant resources, small size and easy modification. In crude oil extraction, Fe (III) is increasingly produced. However, CNCs are very sensitive to Fe (III) and easy to aggregate, which brings obstacles to the application of CNCs.

Co-Colorectal cancer stem cells employ the FADS1/DDA axis to evade NK cell-mediated immunosuppression after co-cultured with NK cells under hypoxia.

Colorectal cancer (CRC) ranks as China's second most common cancer and fifth top cancer death cause. The study highlights the role of Natural Killer (NK) cells in targeting cancer stem cells (CSCs) that evade immune responses in CRC. Colorectal cancer stem cells (CCSCs) were stem from HT-29 cells and co-cultured with NK cells under normoxic or hypoxic conditions.

The modulation of proteomics and antioxidant stress is involved in the effect of nitazoxanide against Japanese encephalitis virus in vitro.

Japanese encephalitis virus (JEV) is a significant circulating arbovirus flavivirus and the primary cause of viral encephalitis in Asia. Previous studies have demonstrated that nitazoxanide (NTZ), an antiparasitic gastroenteritis medication classified as a thiazolide, exhibits efficacy against JEV both in vitro and in vivo. To explore the potential antiviral mechanisms, we employed Tandem Mass Tag (TMT)-based quantitative proteomics to identify differentially expressed proteins (DEPs) among three groups: Blank cell group, JEV-infected cell group, and JEV-infected cells treated with NTZ.
