Deep learning-based classification of traditional Chinese medicine: a novel approach.

Background: As China's economy enters a new period of development, traditional Chinese culture is receiving more and more attention, and the status and role of traditional Chinese medicine (TCM) in economic and social development are also becoming more and more important, and TCM has become a unique health resource. In recent years, TCM has developed into a complete theoretical system and gradually spread abroad. Chinese herbal medicine (CHM) is an important part of TCM; however, its development and spread is seriously hampered by the fact that due to the wide variety and the large number of low-quality products in the market, professionals are required to identify TCMs accurately.

DDTC-Cu(I) Nano-MOF Induces Ferroptosis by Targeting SLC7A11/GPX4 Signal in Colorectal Cancer.

Drug repurposing has received increasing attention in the field of oncology drug development as an alternative strategy to de novo drug synthesis. Disulfiram (DSF) has a long history of clinical application in alcohol withdrawal, and recent studies have revealed that its metabolite diethyldithiocarbamate (DDTC) can be coordinated with copper ions in vivo to form Cu-DDTC complexes with anticancer activity. However, the insufficient in vivo stability of DSF remains a challenge.

Embedding polydopamine in keratin-based biohydrogels for efficient dye removal.

Keratin-based hydrogels have shown promise as materials for wastewater remediation, yet their low surface area and poor mechanical performance hindered the practical application. To address these challenges, we developed a bowl-shaped polydopamine-loaded sponge bio-hydrogel (BPSH) with a hierarchical porous structure and high stability. The extruded keratin chains facilitated the formation of three distinct macroporous frameworks, while embedding bowl-shaped polydopamine into the bio-hydrogel significantly enhanced the hierarchical porous structure.

Analgesic effect of microneedle with 3-acetylaconitine for neuropathic pain.

Neuropathic pain is a worldwide problem that causes physical and psychological pain to many patients. 3-acetylaconitine (AAC) is a kind of non-narcotic analgesic with long-lasting action, non-tolerant and non-addiction. However, it has some cardiac toxicity and can easily cause toxic organ damage.

Soluble microneedle acupuncture patches containing melittin liposomes for the percutaneous treatment of rheumatoid arthritis.

Bee venom acupuncture (BVA) offers therapeutic potential for rheumatoid arthritis (RA) but faces challenges from pain and allergies linked to live bee stings. A key hurdle is melittin (Mel), bee venom's main anti-inflammatory component, which degrades rapidly when orally ingested, leading to decreased efficacy and increased toxicity. This study proposes a solution by encapsulating melittin in liposomes to enhance stability and lessen side effects, expanding its clinical applicability.

Addition of Ostrea rivularis polysaccharides in microneedle loaded with 3-acetylaconitine liposomes enhance analgesic activities and drug delivery properties.

Two dissolvable microneedle (MN) systems, AAC-ORP-MN and AAC-MN, loaded with AAC liposomes (AAC-Lips) either mixed with or without Ostrea rivularis polysaccharide (ORP) were developed. The size, zeta potential and encapsulation efficiency of AAC-Lips were 112.

The characterization of microneedles was conducted and a rat model of monosodium iodoacetate (MIA)-induced KOA was established to evaluate the anti-inflammatory and analgesic activity in this study.

Accurate brain pharmacokinetic parametric imaging using the blood input function extracted from the cavernous sinus.

Brain pharmacokinetic parametric imaging based on dynamic positron emission tomography (PET) scan is valuable in the diagnosis of brain tumor and neurodegenerative diseases. For short-axis PET system, standard blood input function (BIF) of the descending aorta is not acquirable during the dynamic brain scan. BIF extracted from the intracerebral vascular is inaccurate, making the brain parametric imaging task challenging.

DDTC-Cu(I) based metal-organic framework (MOF) for targeted melanoma therapy by inducing SLC7A11/GPX4-mediated ferroptosis.

Disulfiram (DSF), a drug for alcohol withdrawal, has attracted extensive scientific attention due to its potential to treat cancer. The metabolite of DSF, diethyl dithiocarbamate (DDTC), forms a Cu-DDTC complex in vivo with copper ions, which has been shown to be a proteasome inhibitor with high antitumor activity. However, the in vivo stability of Cu-DDTC complexes remains a challenge.

Biomimetic modification on the microporous surface of cardiovascular materials to accelerate endothelialization and regulate intimal regeneration.

Vascular stents are widely used in the clinical treatment of coronary heart disease, but the long-term safety still needs to be improved. Surface biological functional modification is an effective way to improve the biocompatibility and clinical performance of cardiovascular materials, but how to achieve long-term effective and precise regulation of in situ vascular intimal repair through the reasonable construction of the surface physical and chemical structure is still an important task in the current surface modification research. In this study, ECM-derived components, including laminin, heparin, and SDF-1, were incorporated into the titanium surface with a microporous structure.

Protective effect of polysaccharides from Ostrea rivularis against reproductive injury via regulating autophagy induced by oxidative stress.

The objective of this study was to investigate the effect of polysaccharides from Ostrea rivularis (ORP) relieving reproductive damage by regulating autophagy. The results showed that ORP intervention could alleviate the pathological changes of the testis and alleviate oxidative stress which were caused by cyclophosphamide (CTX) in vivo, including improve sperm symptoms and rise testosterone level. Reduced level of autophagy after ORP intervention was observed by transmission electron microscopy (TEM), which implied that ORP might regulate cell autophagy.

Exploiting the Twisted Intramolecular Charge Transfer Effect to Construct a Wash-Free Solvatochromic Fluorescent Lipid Droplet Probe for Fatty Liver Disease Diagnosis.

The prominent pathological feature of fatty liver disease lesions is excessive fat accumulation in lipid droplets in hepatocytes. Thus, developing fluorescent lipid droplet-specific probes with high permeability and a high imaging contrast provides a robust tool for diagnosing fatty liver diseases. Herein, we rationally developed a novel donor-acceptor lipophilic fluorescent probe ANI with high photostability for wash-free visualization of lipid droplets and fatty liver disease characteristics.

Fucoidans from ameliorate renal interstitial fibrosis inhibition of the PI3K/Akt/NF-κB signaling pathway.

The effects of polysaccharides (CFPs) on renal interstitial fibrosis by regulating the phosphatidylinositol-3-hydroxykinase/protein kinase-B/nuclear factor-κB (PI3K/AKT/NF-κB) signaling pathway were investigated and in this research. The common unilateral urethral obstruction (UUO) model was used to examine the renoprotective effect and its mechanism . Compared to the UUO group, CFP administration could ameliorate renal function, inhibit inflammation and fibrosis, and reduce the deposition of the extracellular matrix and epithelial-mesenchymal transition.

Progress on Precise Regulation of Vascular Intimal Repair by a Surface Coating of Vascular Stent.

In the past few decades, drug-eluting stents have made significant contributions to the treatment of coronary heart disease. However, due to the delayed healing of endothelial injuries caused by antiproliferative drugs and insufficient biocompatibility of vascular stent materials, late in-stent thrombosis and restenosis remain major challenges. Surface modification of cardiovascular materials to construct a biological functional layer that can regulate the behavior of blood and vascular cells is an effective way to improve the clinical performance of vascular stents.
