Pancreatic ductal adenocarcinoma (PDAC) is the third leading cause of cancer-related death in the United States, exhibiting a five-year overall survival (OS) of only 7% despite aggressive standard of care. Recent advances in immunotherapy suggest potential application of immune-based treatment approaches to PDAC. To explore this concept further, we treated orthotopically established K-ras(G12D)/p53(-/-) PDAC tumors with gemcitabine and a cell-based vaccine previously shown to generate durable cell-mediated (TH1) immunity...

We assessed implementation of precision medicine within the Veterans Health Administration. We analyzed the use of interleukin-28B (IL28B) pharmacogenetic test, which predicts interferon-α treatment response in patients with hepatitis C. Patients with favorable CC genotype exhibit a two-fold higher response than patients with less favorable genotypes (CT and TT). Linking IL28B tests to Veterans Health Administration clinical data, we analyzed test use, concordance with guidelines, subsequent interferon-α treatment, and site variations...

[Background] Amyloid-β oligomers (AβO) are species mainly involved in the synaptic and cognitive dysfunction in Alzheimer's disease. Although their action has been described mainly at neuronal level, it is now clear that glial cells govern synaptic activity in their resting state, contributing to new learning and memory establishment. In contrast, when activated, they may lead to synaptic and cognitive dysfunction. Using a reliable acute AβO-mediated mouse model of AD, we explored whether the memory alteration AβOs induce relies on the activation of glial cells, and if Toll-like receptor 4 (TLR4), pivotal in the initiation of an immune response, is involved...

Metabolic Syndrome (MetS) is one of the most common factors underlying the high rate of mortality observed in patients with schizophrenia. Recent research on this topic revealed that many of the patients studied were, in fact, in a medicated state. As such, it is unclear whether MetS is causally associated with the disorder itself or the medication used to treat it. In this study, patients with a clinically high risk of expressing first episode psychosis (CHR) were examined regarding the prevalence of MetS...

Global temperatures continue to rise, reaching new records almost every year this decade. Although the causes are debated, climate change is a reality. Consequences of climate change include melting of the arctic ice cap, rising of sea levels, changes in precipitation patterns, and increased severe weather events. This article updates dermatologists about the effects of climate change on the epidemiology and geographic ranges of selected skin diseases in North America. Although globalization, travel, and trade are also important to changing disease and vector patterns, climate change creates favorable habitats and expanded access to immunologically naïve hosts...

In human ESCs the transcription factor Zeb2 regulates neuroectoderm versus mesendoderm formation, but it is unclear how Zeb2 affects the global transcriptional regulatory network in these cell-fate decisions. We generated Zeb2 knockout (KO) mouse ESCs, subjected them as embryoid bodies (EBs) to neural and general differentiation and carried out temporal RNA-sequencing (RNA-seq) and reduced representation bisulfite sequencing (RRBS) analysis in neural differentiation. This shows that Zeb2 acts preferentially as a transcriptional repressor associated with developmental progression and that Zeb2 KO ESCs can exit from their naïve state...

BACKGROUND:  Uptake of the human papillomavirus (HPV) vaccine in the United States is slow, and the real-world effectiveness of the vaccine has not been assessed in high-risk adolescent populations. METHODS:  We conducted a longitudinal study of 1139 sexually-active, inner-city adolescent women receiving the 3-dose quadrivalent (4vHPV) vaccine. Cervical and anal specimens collected semi-annually were tested using a L1-PCR assay. Post-vaccination incidence of 4vHPV vaccine and non-vaccine HPV types, and risk of cervical cytological abnormalities, were assessed in relation to time-to-completion of all three vaccine doses...

Objectives Binocular depth inversion illusion (BDII) represents an illusion of visual perception that involves higher-order visual and cognitive processes. Its impairment has been linked to psychotic conditions and identified as a marker for at risk mental states. The endogenous cannabinoid system (ECS) is involved in various neurophysiological processes. One of its key components, anandamide, is involved in the pathophysiology of schizophrenia. Little is known about its impact on BDII alterations. Therefore, we explored associations between BDII and anandamide levels...

The enhancer landscape is dramatically restructured as naive preimplantation epiblasts transition to the post-implantation state of primed pluripotency. A key factor in this process is Otx2, which is upregulated during the early stages of this transition and ultimately recruits Oct4 to a different set of enhancers. In this study, we discover that the acetylation status of Oct4 regulates the induction of the primed pluripotency gene network. Maintenance of the naive state requires the NAD-dependent deacetylase, SirT1, which deacetylates Oct4...

Macrophages can be activated into several distinct activation states. One of these states, type II activation, has a regulatory phenotype characterized by decreased IL-12 and increased IL-10, and has been shown to bias naïve CD4+ T cells to a Th2 response. Microglia, the resident macrophage-like cells in the central nervous system (CNS), are important contributors to neuroinflammation and, thus, we investigated if type II activated microglia could bias CD4+ T cell responses in a similar manner as type II activated macrophages...

RATIONALE: Adult rat 50-kHz vocalizations have been proposed to indicate a positive affective state, putatively revealed by a predominance of trill calls over flat calls. However, short-term exposure to non-sedative doses of the euphorigen morphine suppresses calling, with no discernible shift in trill or flat call prevalence. OBJECTIVES: This study aimed to determine whether morphine acutely increases 50-kHz call rates or alters the relative prevalence of trill or flat calls, after long-term morphine exposure or acute pharmacological pretreatment...

CONTEXT: The available data concerning oxidant stress and antioxidant capacity in hypothyroidism are scanty and inconclusive. While some authors suggest that tissues may be protected from oxidant damage because of a hypometabolic state in hypothyroidism, others report increased oxidative stress in hypothyroidism. Selenium acts as a cofactor for the thyroid hormone (TH) deiodinases that activate and then deactivate various THs and their metabolites. Selenium may inhibit thyroid autoimmunity...

Functional magnetic resonance imaging studies have significantly expanded the field's understanding of functional brain activity of healthy and patient populations. Resting state (rs-) fMRI, which does not require subjects to perform a task, eliminating confounds of task difficulty, allows examination of neural activity and offers valuable functional mapping information. The purpose of this work was to develop an automatic resting state network (RSN) labeling method which offers value in clinical workflow during rs-fMRI mapping by organizing and quickly labeling spatial maps into functional networks...
