Epigallocatechin gallate (EGCG), a major polyphenol in green tea, inhibits the type III secretion system (T3SS) of enteropathogenic and enterohaemorrhagic Escherichia coli (EPEC and EHEC, respectively), Salmonella enterica serovar Typhimurium, and Yersinia pseudotuberculosis. The inhibitory effect causes the inhibition of hemolysis, cell invasion, cell adhesion, and apoptosis, which are functions of the type III secretion device. In the case of EPEC, EspB accumulates in the cells. RT-PCR showed that the translation of EspB was not blocked...

The pro-inflammatory cytokine interleukin-1β (IL-1β) may be involved in several ovulation-associated events, such as proteases synthesis, prostaglandin production and steroidogenesis in granulosa cells. However, the exact effect of IL-1β on progesterone synthesis in granulosa cells and the underlying mechanism remain unclear. By using cultured granulosa-lutein cells collected from women undergoing in vitro fertilization or intracytoplasmic sperm injection, we found that IL-1β up-regulated steroidogenic acute regulatory protein (StAR) expression and progesterone synthesis in granulosa-lutein cells, which was comparable with luteinizing hormone (LH) effect and could be abolished by an IL-1 receptor antagonist...

High-resolution (13)C NMR spectroscopy of hyperpolarized succinate-1-(13)C-2,3-d2 is reported in vitro and in vivo using a clinical-scale, biplanar (80cm-gap) 48.7mT permanent magnet with a high homogeneity magnetic field. Non-localized (13)C NMR spectra were recorded at 0.52MHz resonance frequency over the torso of a tumor-bearing mouse every 2s. Hyperpolarized (13)C NMR signals with linewidths of ∼3Hz (corresponding to ∼6ppm) were recorded in vitro (2mL in a syringe) and in vivo (over a mouse torso). Comparison of the full width at half maximum (FWHM) for (13)C NMR spectra acquired at 48...

The gold(III)-dithiocarbamate complex AuL12 (dibromo [ethyl-N-(dithiocarboxy-kS,kS')-N-methylglycinate] gold(III)), is endowed with promising in vitro/in vivo antitumor activity and toxicological profile. Here, we report our recent strategies to improve its water solubility and stability under physiological conditions along with our efforts for unravelling its tangled mechanism of action. We used three types of α-cyclodextrins (CDs), namely β-CD, Me-β-CD and HP-β-CD to prepare aqueous solutions of AuL12...

Interferon Regulatory Factor (IRF-3) has been shown to contribute to immune control of B16 melanoma tumor growth. We have shown previously that IRF-3 has a role in IFN-γ-induced expression of pro-apoptotic interferon stimulated gene 54 (ISG54) in macrophages and IFN-γ in T cells. To investigate the IRF3-IFN-γ-ISG54 nexus, we injected C57Bl/6 (B6) and IRF3KO mice s.c. with luciferase-producing B16-F10 tumor cells. Tumor growth as measured by luciferase levels was similar between B6 and IRF3KO mice at days 2 and 6, but was significantly greater at day 9 in IRF3KO mice compared with B6 mice...

BACKGROUND: Increased utilisation of needle-syringe programs (NSP) by men who inject performance and image-enhancing drugs (PIEDs) has been reported. While fewer in number, people who inject PIEDs possess distinct service and knowledge needs compared to other NSP clients. METHODS: Using standardised data from 26 NSP outlets through the Queensland NSP Minimum Data Set (QNSPMDS), trends in occasions of services among males intending to inject PIEDs were assessed using multilevel mixed-effects negative binomial regression, adjusting for month, year, and age, and clustering by site...

REVIEW

Hemophilia A is a bleeding disorder caused by mutations in the gene encoding factor VIII (FVIII), a cofactor protein that is essential for normal blood clotting. Approximately, 1 in 3 patients with severe hemophilia A produce neutralizing antibodies (inhibitors) that block its biologic function in the clotting cascade. Current efforts to eliminate inhibitors consist of repeated FVIII injections under what is termed an "ITI" protocol (Immune Tolerance Induction). However, this method is extremely costly and approximately 30% of patients undergoing ITI do not achieve peripheral tolerance...

Prenatal exposure to lipopolysaccharide (LPS), which likely occurs due to infection or contact with environmental allergens during pregnancy, is a proposed risk factor that induces anxiety- and autism spectrum disorder-like behaviors in offspring. However, the molecular and behavioral changes in offspring after maternal immune activation have not been completely identified. We hypothesized that a subcutaneous injection of LPS in a pregnant mouse would induce changes in cerebral serotonin (5-HT) in parallel to the appearance of anxiety-like behaviors in the dam's offspring...

Stimuli-responsive micro-supercapacitors (MSCs) controlled by external stimuli can enable a wide range of applications for future on-chip energy storage. Here, we report on a photoswitchable MSC based on a diarylethene-graphene composite film. The micro-device delivers an outstanding and reversible capacitance modulation of up to 20%, demonstrating a prototype photoswitchable MSC. Terahertz spectroscopy indicates that the photoswitching of the capacitance is enabled by the reversible tuning of interfacial charge injection into diarylethene molecular orbitals, as a consequence of charge transfer at the diarylethene-graphene interface upon light modulation...

With the number of deaths due to stroke decreasing, more individuals are forced to live with crippling disability resulting from the stroke. To date, no therapeutics exist after the first 4.5 h after the stroke onset, aside from rest and physical therapy. Following stroke, a large influx of astrocytes and microglia releasing proinflammatory cytokines leads to dramatic inflammation and glial scar formation, affecting brain tissue's ability to repair itself. Pathological conditions, such as a stroke, trigger neural progenitor cells (NPCs) proliferation and migration toward the damaged site...

Previous research to investigate the interaction between malaria infection and tumor progression has revealed that malaria infection can potentiate host immune response against tumor in tumor-bearing mice. Exosomes may play key roles in disseminating pathogenic host-derived molecules during infection because several studies have shown the involvement and roles of extracellular vesicles in cell-cell communication. However, the role of exosomes generated during Plasmodium infection in tumor growth, progression and angiogenesis has not been studied either in animals or in the clinics...
