A hybrid bacterium with tumor-associated macrophage polarization for enhanced photothermal-immunotherapy.

Remodeling the tumor microenvironment through reprogramming tumor-associated macrophages (TAMs) and increasing the immunogenicity of tumors immunogenic cell death (ICD) have been emerging as promising anticancer immunotherapy strategies. However, the heterogeneous distribution of TAMs in tumor tissues and the heterogeneity of the tumor cells make the immune activation challenging. To overcome these dilemmas, a hybrid bacterium with tumor targeting and penetration, TAM polarization, and photothermal conversion capabilities is developed for improving antitumor immunotherapy .

IFC-305 attenuates renal ischemia-reperfusion injury by promoting the production of hydrogen sulfide (HS) via suppressing the promoter methylation of cystathionine γ-lyase (CSE).

Renal ischemia-reperfusion (I/R) injury is characterized by elevated expression of homocysteine and decreased production of hydrogen sulfide (HS). Cystathionine γ-lyase (CSE) is a key factor in the onset of renal I/R injury, while IFC-305 can regulate the expression of CSE via epigenetic modification. Animal and cellular models of I/R were established in this work, followed by H&E staining to evaluate the extent of renal tissue injury under distinct conditions.

Relapsed boyhood tibia polymicrobial osteomyelitis linked to dermatophytosis: a case report.

Background: Relapsed childhood polymicrobial osteomyelitis associated with dermatophytosis has not been reported in the literature.

Case Presentation: Here we report on a case of a 45-year-old man who had left tibial osteomyelitis for 29 years, accompanied by skin fungal infection of the ipsilateral heel for 20 years, and underwent a second operation due to recurrence of polymicrobial infection 6 years ago. The patient had a history of injury from a rusty object, which penetrated the anterior skin of the left tibia middle segment causing subsequent bone infection, but was asymptomatic after receiving treatments in 1983.

Drug self-delivery nanorods enhance photodynamic therapy of triple-negative breast cancer by inhibiting oxidative phosphorylation.

Photodynamic therapy (PDT) shows very high potential for the clinical treatment of triple-negative breast cancer. However, the efficacy of PDT is significantly weakened by tumor hypoxia, the relatively high intracellular glutathione levels and the active proliferation of cancer cells. To address these issues, we developed a novel drug self-delivery nanorod (defined as AINRs) through the hydrophobic interaction among the mitochondrial complex III inhibitor (atovaquone, ATO), the photosensitizer (indocyanine green, ICG) and the dispersion stabilizer (distearoyl phosphoethanolamine-polyethylene glycol 2000, DSPE-PEG 2000).

Protective Effect of Ginsenosides from Stems and Leaves of against Scopolamine-Induced Memory Damage via Multiple Molecular Mechanisms.

Although growing evidence has shown that ginsenosides from stems and leaves of (GSLS) exercise a protective impact on the central nervous system, in the model of memory damage induced by scopolamine, it is still rarely reported. Thus, the mechanism of action needs to be further explored. This study was to investigate the effect of GSLS on scopolamine (SCOP)-induced memory damage and the underlying mechanism.

The PARP1 Inhibitor Niraparib Represses DNA Damage Repair and Synergizes with Temozolomide for Antimyeloma Effects.

Purpose: Poly(ADP-ribose) polymerase 1 (PARP1) is necessary for single-strand break (SSB) repair by sensing DNA breaks and facilitating DNA repair through poly ADP-ribosylation of several DNA-binding and repair proteins. Inhibition of PARP1 results in collapsed DNA replication fork and double-strand breaks (DSBs). Accumulation of DSBs goes beyond the capacity of DNA repair response, ultimately resulting in cell death.

Ligustrazine Attenuates Liver Fibrosis by Targeting miR-145 Mediated Transforming Growth Factor-/Smad Signaling in an Animal Model of Biliary Atresia.

To investigate therapeutic target for ligustrazine during liver fibrosis in an ethanol-induced biliary atresia rat model and transforming growth factor- (TGF-) induced hepatic stellate cell activation cell model, and the underlying mechanism, a total of 30 rats were randomly assigned into five groups ( = 6 per group): control, sham, ethanol-induced biliary atresia model, model plus pirfenidone, and model plus ligustrazine groups. The liver changes were assessed using H&E and Masson staining and transmission electron microscopy. Expression of miR-145 and mRNA and protein levels of TGF-/smads pathway-related proteins were detected.

Here, we found that ITCH was downregulated, while JAG1 was upregulated in OA tissues compared to normal cartilaginous tissues.

Integrated US-OCT-NIRF Tri-Modality Endoscopic Imaging System for Pancreaticobiliary Duct Imaging.

Pancreaticobiliary carcinomas is a highly malignant gastrointestinal tumor. Most pancreaticobiliary cancers arise from epithelial proliferation within the pancreaticobiliary ducts, referred to as pancreatic intraepithelial neoplasias (PanINs). Some PanINs are benign metaplasia, while others progress to invasive duct adenocarcinoma (IDAC).
