In cancer therapy, addressing the tumor microenvironment remains a critical challenge. This study presented a novel drug delivery system based on thiolated fucoidan (FUC-SH), a marine-derived polysaccharide possessing immunomodulatory properties. FUC-SH was synthesized via cysteine conjugation and self-assembled with doxorubicin (DOX) to form stable nanoparticles through electrostatic interactions and disulfide crosslinking.

Impaired fatty acid oxidation (FAO) and the therapeutic benefits of FAO restoration have been revealed in sepsis. However, the regulatory factors contributing to FAO dysfunction during sepsis remain inadequately clarified. In this study, we identified a subset of lipid-associated macrophages characterized by high expression of trigger receptor expressed on myeloid cells 2 (TREM2) and demonstrated that TREM2 acted as a suppressor of FAO to increase the susceptibility to sepsis.

Article Synopsis
  • Keratitis caused by microbial infection leads to serious inflammation of the cornea, and miRNAs like miR-155 are important in regulating the body's response to such infections.
  • In this study, it was found that miR-155 levels were significantly higher in both macrophages and corneal tissue post-infection, and mice lacking miR-155 were more resistant to keratitis, having lower levels of bacteria.
  • The research revealed that miR-155 promotes apoptosis (cell death) in macrophages during infection by inhibiting the PI3K-Akt signaling pathway, suggesting that targeting miR-155 could be a potential therapeutic strategy for treating keratitis and similar infections.

In this work, a triphenylamine-benzofuran-derived fluorescent probe TBSF was developed for monitoring the sulfite level in Chinese medicinal materials and imaging in living cells. In the testing system, under 445 nm excitation, TBSF responded to sulfite steadily with a 540 nm fluorescence reporting signal. The testing system showed advantages including high sensitivity, rapid response, and high selectivity.

Background: Danshen Chuanxiong Injection (DCI) has demonstrated significant clinical efficacy in the treatment of acute pancreatitis (AP); however, the precise molecular mechanisms underlying its therapeutic effects remain incompletely understood.

Objective: In this study, we employed network pharmacology analysis to comprehensively investigate the active components, potential targets, and signaling pathways involved in DCI-mediated treatment of AP.

Methods: We utilized the mouse pancreatic acinar cell line 266-6 to establish an cholecystokinin (CCK)-induced AP cell injury model and evaluated cell viability using the Cell counting kit-8 assay.

No previous meta-analysis had explored the association between vitamin D supplementation in healthy pediatrics and the risk of acute respiratory tract infections (ARTIs). Thus, we meta-analyzed the current evidence in this regard to provide sufficient knowledge about this risk-benefit ratio for vitamin D supplementation in this specific age group. We searched seven databases for randomized controlled trials (RCTs) that investigated the effect of vitamin D supplementation and ARTIs risk on a healthy pediatric population (0-18 years old).

Immune checkpoint blockade has emerged as a significant therapeutic development in immunotherapy during the past decade. However, only a small percentage of cancer patients respond to checkpoint blockade, suggesting that a fundamental knowledge of the underlying processes of immune checkpoint receptor signaling remains elusive and that novel therapeutic medications are needed. Here, the programmed cell death protein 1(PD-1) expressing nanovesicles were developed to enhance T cell activity.

Linezolid is an oxazolidinone antibacterial drug, and its therapeutic drug monitoring and individualized treatment have been challenged since its approval. With the in-depth clinical research of linezolid, we have changed our attitude toward its therapeutic drug monitoring and our view of individualized treatment. On the basis of summarizing the existing clinical studies, and based on the practical experience of each expert in their respective professional fields, we have formed this expert consensus.

Thrombin is the most potent platelet aggregator. To discover the selective inhibitor of thrombin that is important to curing platelet aggregation-related diseases, docking experiments were performed to dock (1R,3S)-2,3,4,9-tetrahydro-β-carboline-3- carboxylic acid, [(1R,3S)-THCCA], and (1S,3S)-2,3,4,9-tetrahydro-β-carboline-3- carboxylic acid, [(1S,3S)-THCCA], into the p pocket of bovine thrombin. The ideal match supported that (1R,3S)-THCCA could be used as a potential lead compound.

Objective: To explore the curative effect of laparoscopic surgery combined with leuprorelin in the treatment of endometriosis with infertility and the related factors of recurrence after treatment.

Methods: A total of 158 patients with endometriosis and infertility were selected in our hospital from January 2019 to June 2020. Patients were randomly divided into the control group and the observation group, with 79 patients in each group.

Pluronic modified polyamidoamine (PAMAM) conjugate (PF127-PAMAM) was prepared and the inhibiting effect of MDR against MCF-7/ADR was investigated with doxorubicin (DOX) as model drug. 1H NMR and FTIR spectra showed that the conjugate was synthesized successfully. Element analysis accurately measured that 27.

Context: Polyamidoamine (PAMAM) dendrimers have attracted lots of interest as drug carriers. And little study about whether pluronic-attached PAMAM dendrimers could be potential drug delivery systems has been carried on.

Objective: Pluronic F127 (PF127) attached PAMAM dendrimers were designed as novel drug carriers.
