In the present work, the effect of graphene oxide (GO) nanosheets on the antibacterial activity of CuO nanowire arrays under visible light irradiation is shown. A combined thermal oxidation/electrophoretic deposition technique was employed to prepare three-dimensional networks of graphene oxide nanosheets hybridized with vertically aligned CuO nanowires. With the help of standard antibacterial assays and X-ray photoelectron spectroscopy, it is shown that the light-activated antibacterial response of the hybrid material against gram-negative Escherichia coli is significantly improved as the oxide functional groups of the GO nanosheets are reduced...

Despite significant advances in the treatment of multiple myeloma (MM), most patients succumb to disease progression. One of the major immunosuppressive mechanisms that is believed to play a role in myeloma progression, is the expansion of regulatory T-cells (Tregs). In this study, we demonstrate that myeloma cells drive Treg expansion and activation by secreting type-1 interferon (IFN). Blocking IFNAR1 (interferon alpha and beta receptor 1) on Tregs significantly decreases both, myeloma-associated Treg immunosuppressive function and myeloma progression...

Herpes simplex virus type 2 (HSV-2) is among the most prevalent sexually transmitted infections in the United States. Despite this, there has been limited research on the correlates to HSV-2 among disadvantaged and marginalized women, particularly among Latinas. Data for the present analysis include 125 young adult Mexican-American women enrolled in a longitudinal study in a disadvantaged urban community in San Antonio, Texas. The current rate of tested HSV-2 infection is 56.8%. Our findings suggest strong comorbidity of genital herpes with injecting heroin use, Hepatitis C, sexual violence, incarceration, and mental illness...

BACKGROUND: Botulinum toxin type A (BoNT-A) injections is the accepted first-line therapy for cervical dystonia (CD), however, numerous patients discontinue treatment early due to perceived sub-optimal relief. To improve BoNT-A therapy for CD, proper assessment of neck motion and selection of relevant muscles and dosing must be met. Kinematic technology may improve treatment outcomes by guiding physicians to better tailor muscle selection and BoNT-A dosing for CD therapy. METHODS: 28 CD participants were placed into either group: expert injector determined injection patterns by visual assessment ("vb") versus injection patterns based on kinematics interpreted by an expert injector ("kb")...

BACKGROUND: The hepatocyte growth factor (HGF) target pathway plays pivotal renoprotective roles after acute kidney injury (AKI). Syndecan-1 serves as the co-receptor for HGF. Shedding of syndecan-1 is involved in various pathological processes. Thus, we hypothesized that IRI induced syndecan-1 shedding and inhibiting syndecan-1 shedding would protect against kidney injury by potentiating activation of the HGF receptor c-Met. METHODS: Expression of syndecan-1 and its sheddases were observed in kidneys of sham and I/R mice...

PURPOSE: Pneumococcal virulence protein-based vaccines can provide serotype-independent protection against pneumococcal infections. Many studies, including clinical observational studies on Thomsen-Friedenrich antigen exposure and haemolytic uremic syndrome, defined the role of neuraminidases NanA, NanB and NanC in host-pneumococcus interaction. Since neuraminidases are major virulence proteins, they are potential targets for both vaccines and small molecule inhibitors. Here we explored the utility of three neuraminidases as protein vaccine antigens to generate neutralizing antibodies and to increase survival following pneumococcal infections...
