Upregulation of TREM2 expression in M2 macrophages promotes chronic infection.

() is a zoonotic bacterial pathogen that causes chronic host infections. The eradication of brucellosis using antibiotic therapy is often incomplete or slow. In a mouse model, the predominance of alternatively activated macrophages (also known as M2) plays an essential role in sustaining chronic infection.

Platycodin D2 enhances P21/CyclinA2-mediated senescence of HCC cells by regulating NIX-induced mitophagy.

Background: Hepatocellular carcinoma (HCC) cells usually show strong resistance to chemotherapy, which not only reduces the efficacy of chemotherapy but also increases the side effects. Regulation of autophagy plays an important role in tumor treatment. Cell senescence is also an important anti-cancer mechanism, which has become an important target for tumor treatment.

A rare presentation of central pontine myelinolysis secondary to hyperglycaemia.

Background: Central pontine myelinolysis (CPM) is a rare demyelinating disorder caused by the loss of myelin in the center of the basis pontis. CPM typically occurs with rapid correction of severe chronic hyponatremia and subsequent disturbances in serum osmolality. Although hyperglycaemia is recognized as a pathogenetic factor in serum osmolality fluctuations, CPM is rarely seen in the context of diabetes.

Flow cytometry, fluorescence staining, Western blot, T-AOC, DPPH radical scavenging assay, hydroxyl radical's inhibitory capability and GSH test were used to examine the esculetin's effects on the ROS level, the oxidation-related substances and proteins' expression in hepatoma cells.

Implications of p53 in mitochondrial dysfunction and Parkinson's disease.

To study the underlying molecular mechanisms of p53 in the mitochondrial dysfunction and the pathogenesis of Parkinson's disease (PD), and provide a potential therapeutic target for PD treatment. We review the contributions of p53 to mitochondrial changes leading to apoptosis and the subsequent degeneration of dopaminergic neurons in PD. P53 is a multifunctional protein implicated in the regulation of diverse cellular processes via transcription-dependent and transcription-independent mechanisms.

Recent progress in nanocomposites of carbon dioxide fixation derived reproducible biomedical polymers.

In recent years, the environmental problems accompanying the extensive application of biomedical polymer materials produced from fossil fuels have attracted more and more attentions. As many biomedical polymer products are disposable, their life cycle is relatively short. Most of the used or overdue biomedical polymer products need to be burned after destruction, which increases the emission of carbon dioxide (CO).

Material And Methods: Clinical data of 211 patients with cervical cancer, treated at our institution between June 2014 and February 2017 were reviewed retrospectively. All patients were treated with definitive radiotherapy and received external irradiation of 45-50.

The Effector BspI Suppresses Inflammation via Inhibition of IRE1 Kinase Activity during Infection.

Mammalian GTPase-activating proteins (GAPs) can inhibit innate immunity signaling in a spatiotemporal fashion; however, the role of bacterial GAPs in mediating innate immunity remains unknown. In this study, we show that BspI, a type IV secretion system (T4SS) effector protein, containing a GAP domain at the C terminus, negatively regulates proinflammatory responses and host protection to infection in a mouse model. In macrophages, BspI inhibits the activation of inositol-requiring enzyme 1 (IRE1) kinase, but it does not inhibit activation of ATF6 and PERK.

In vivo and in vitro inhibition of SCLC by combining dual cancer-specific recombinant adenovirus with Etoposide.

Purpose: Oncolytic virotherapy is emerging as an important modality in cancer treatment. In a previous study, we designed and constructed Ad-Apoptin-hTERTp-E1a (Ad-VT), a dual cancer-selective anti-tumor recombinant adenovirus.

Methods: To explore the therapeutic effect of recombinant adenovirus Ad-VT together with Etoposide on small cell lung cancer, the ability of Ad-VT alone, Etoposide alone, and a combination of Ad-VT + Etoposide to inhibit proliferation of NCI-H446 and BEAS-2B cells was investigated using the WST-1 method.

Controlled Aggregation of a Perylene-Derived Probe for Near-Infrared Fluorescence Imaging and Phototherapy.

The design and synthesis of water-soluble phototherapeutic agents with near-infrared (NIR) fluorescence emission is highly desirable for cancer diagnosis and treatment. Here, we report the construction of an amphiphilic perylene-derived photosensitizer, AP. AP shows NIR emission with large Stokes shift (130 nm) and high O quantum yield (22%).

Apoptin induces pyroptosis of colorectal cancer cells via the GSDME-dependent pathway.

Apoptin is a small molecular weight protein encoded by the VP3 gene of chicken anemia virus (CAV). It can induce apoptosis of tumor cells and play anti-tumorigenic functions. In this study, we identified a time-dependent inhibitory role of apoptin on the viability of HCT116 cells.

Ad-VT enhances the sensitivity of chemotherapy-resistant lung adenocarcinoma cells to gemcitabine and paclitaxel in vitro and in vivo.

Background One of the main challenges in the clinical treatment of lung cancer is resistance to chemotherapeutic drugs. P-glycoprotein (P-gp)-mediated drug resistance is the main obstacle to successfully implementing microtubule-targeted tumor chemotherapy. Purpose In this study, we explored the effect of Ad-hTERTp-E1a-Apoptin (Ad-VT) on drug-resistant cell lines and the molecular mechanism by which Ad-VT combined with chemotherapy affects drug-resistant cells and parental cells.

Novel insights into the consequences of obesity: a phenotype-wide Mendelian randomization study.

Obesity is thought to significantly impact the quality of life. In this study, we sought to evaluate the health consequences of obesity on the risk of a broad spectrum of human diseases. The causal effects of exposing to obesity on health outcomes were inferred using Mendelian randomization (MR) analyses using a fixed effects inverse-variance weighted model.

Anti-tumour effects of a dual cancer-specific oncolytic adenovirus on Breast Cancer Stem cells.

Apoptin can specifically kill cancer cells but has no toxicity to normal cells. Human telomerase reverse transcriptase (hTERT) can act as a tumour-specific promoter by triggering the expression of certain genes in tumour cells. This study aims to investigate the inhibitory effects and to explore the inhibitory pathway of a dual cancer-specific recombinant adenovirus (Ad-apoptin-hTERTp-E1a, Ad-VT) on breast cancer stem cells.
