Perspectives of traditional herbal medicines in treating retinitis pigmentosa.

Medicinal plants, also known as herbs, have been discovered and utilized in traditional medical practice since prehistoric times. Medicinal plants have been proven rich in thousands of natural products that hold great potential for the development of new drugs. Previously, we reviewed the types of Chinese traditional medicines that a Tang Dynasty monk Jianzhen (Japanese: Ganjin) brought to Japan from China in 742.

Maimendong decoction inhibits lung cancer metastasis by increasing the proportion and killing activity of NK cells.

Ethnopharmacological Relevance: In China, Maimendong Decoction (MMDD) is a classic Chinese medicine prescription for treating lung diseases, such as cough, upper respiratory tract infection, bronchitis, asthma, pulmonary fibrosis and so on. However, the mechanism by which MMDD inhibits lung cancer metastasis remains unclear.

Aim Of The Study: This study seeks to examine the effect of MMDD on suppressing lung cancer metastasis and to uncover its mechanism through the regulation of tumor immunity.

Design, synthesis, and antiproliferative activity evaluation of novel α-mangostin derivatives by ROS/MAPK signaling pathway.

Novel hydroxamic acid and 3,6-amide modified α-mangostin derivatives were synthesized and evaluated their antiproliferative activities against KYSE 30 (esophageal cancer), HCT 116 (colon cancer), and HGC 27 (gastric cancer) cell lines. Most of the new derivatives displayed stronger anti-proliferative activities compared to α-mangostin. Among all the derivatives, compound 4a exhibited the most potent activity, with IC values of 0.

Anthrax lethal toxin exerts potent metabolic inhibition of the cardiovascular system.

causes anthrax through a combination of bacterial infection and toxemia. As a major virulence factor of , anthrax lethal toxin (LT) is a zinc-dependent metalloproteinase, exerting its cytotoxicity through proteolytic cleavage of the mitogen-activated protein kinase kinases, thereby shutting down the MAPK pathways. Anthrax lethal toxin induces host lethality mostly by targeting the cardiovascular system.

Polysaccharides from Ostrea rivularis alleviate type II diabetes induced-retinopathy and VGEF-induced angiogenesis via PI3K/AKT signaling pathway.

The purpose of this study was to investigate the role of polysaccharides from Ostrea rivularis Gloud (ORPs) in the progression of diabetic retinopathy (DR) and its anti-angiogenic effect on endothelial cell. Transgenic db/db mice with DR model were used to evaluate the protective effect of ORPs on retinal damage. It was found that ORPs could down-regulated levels of random blood glucose and fasting insulin, and further ameliorate retinal structure abnormalities as well as vascular network structure.

Transdermal delivery of iguratimod and colchicine ethosome by dissolving microneedle patch for the treatment of recurrent gout.

This methodology addresses the instability issues present in rat models of gout, providing a more accurate representation of the damage recurrent gout episodes inflict on human skeletal systems. A soluble nanoneedle system encapsulating colchicine and iguratimod ethosomal formulations was developed.

The Programmable Catalytic Core of 8-17 DNAzymes.

8-17 DNAzymes (8-17, 17E, Mg5, and 17EV1) are in vitro-selected catalytic DNA molecules that are capable of cleaving complementary RNAs. The conserved residues in their similar catalytic cores, together with the metal ions, were suggested to contribute to the catalytic reaction. Based on the contribution of the less conserved residues in the bulge loop residues (W, A, A) and the internal stem, new catalytic cores of 8-17 DNAzymes were programmed.

Uncertainty affects cancer-related fatigue among breast cancer women undergoing peripherally inserted central catheter chemotherapy: the chain mediating role of psychological resilience and self-care.

Background: Breast cancer patients undergoing chemotherapy via peripherally inserted central catheter often experience serious behavioral and psychological challenges, with uncertainty and cancer-related fatigue being prevalent issues that profoundly impact prognosis. Therefore, this study aimed to investigate the relationship between uncertainty and cancer-related fatigue by employing a chain mediation model to examine the potential mediating roles of psychological resilience and self-care.

Methods: A cross-sectional study was conducted with 223 breast cancer patients receiving peripherally inserted central catheter chemotherapy at two tertiary affiliated hospitals of China Medical University in Liaoning, China, from February 2021 to December 2022.

Targeting canine mammary neoplastic epithelial cells with a reengineered anthrax toxin: first study.

Mammary tumors are the most frequent type of neoplasms in intact female dogs. New therapies that target neoplastic cells without affecting normal cells are highly sought. The Bacillus anthracis toxin has been reengineered to target tumor cells that express urokinase plasminogen activators and metalloproteinases.

Iron-catalyzed benzylic C-H thiolation photoinduced ligand-to-metal charge-transfer.

Here, we describe an iron-catalyzed benzylic C-H thiolation of alkylarenes photoinduced ligand-to-metal charge-transfer. The protocol features operational simplicity, mild reaction conditions, and the use of FeCl as catalyst and thiols/disulfides as sulfur sources, which enables the transformation of diverse benzylic C-H bonds into C-S bonds with a high efficiency.

Functional Integrity of Radical SAM Enzyme Dph1•Dph2 Requires Non-Canonical Cofactor Motifs with Tandem Cysteines.

The Dph1•Dph2 heterodimer from yeast is a radical SAM (RS) enzyme that generates the 3-amino-3-carboxy-propyl (ACP) precursor for diphthamide, a clinically relevant modification on eukaryotic elongation factor 2 (eEF2). ACP formation requires SAM cleavage and atypical Cys-bound Fe-S clusters in each Dph1 and Dph2 subunit. Intriguingly, the first Cys residue in each motif is found next to another ill-defined cysteine that we show is conserved across eukaryotes.

Identification of ASF1A and HJURP by global H3-H4 histone chaperone analysis as a prognostic two-gene model in hepatocellular carcinoma.

Hepatocellular carcinoma (HCC) is a malignancy with poor prognosis. Abnormal expression of H3-H4 histone chaperones has been identified in many cancers and holds promise as a biomarker for diagnosis and prognosis. However, systemic analysis of H3-H4 histone chaperones in HCC is still lacking.

Isolation, Identification, and Biological Characterization of Phage vB_KpnM_KpVB3 Targeting Carbapenem-Resistant Klebsiella pneumoniae ST11.

Objectives: This study aimed to isolate a phage capable of lysing carbapenem-resistant Klebsiella pneumoniae (CRKP) and to analyse its biological characteristics and whole-genome sequence.

LINC00540 promotes sorafenib resistance and functions as a ceRNA for miR-4677-3p to regulate AKR1C2 in hepatocellular carcinoma.

Sorafenib resistance is one of the main causes of poor prognosis in patients with advanced hepatocellular carcinoma (HCC). Long noncoding RNAs (lncRNAs) function as suppressors or oncogenic factors during tumor progression and drug resistance. Here, to identify therapeutic targets for HCC, the biological mechanisms of abnormally expressed lncRNAs were examined in sorafenib-resistant HCC cells.

This study utilized single-cell transcriptome sequencing to examine the alterations in the TME in response to FVIO-MHT in breast cancer.

SOX4 as a potential therapeutic target for pathological cardiac hypertrophy.

Pathological cardiac hypertrophy can lead to heart failure, making its prevention crucial. SOX4, a SOX transcription factor, regulates tissue growth and development, although its role in pathological cardiac hypertrophy is unclear. We found that the SOX4 expression was elevated in hypertrophic hearts and angiotensin II (Ang II)-treated neonatal rat cardiomyocytes (NRCMs), and knocking down the SOX4 expression in NRCMs and mouse hearts significantly reduced the hypertrophic response.
