Background: Synovial sarcoma (SS) and myxoid/round cell liposarcoma (MRCL) are ideal solid tumors for the development of adoptive cellular therapy (ACT) targeting NY-ESO-1, as a high frequency of tumors homogeneously express this cancer-testes antigen. Data from early phase clinical trials have shown antitumor activity after the adoptive transfer of NY-ESO-1-specific T cells. In these studies, persistence of NY-ESO-1 specific T cells is highly correlated with response to ACT, but patients often continue to have detectable transferred cells in their peripheral blood following progression.

However, clinical trials have shown mixed results, possibly due to heterogeneous methodology and lack of understanding of the underlying mechanism of action. The present study was undertaken to understand the specific contribution of somatosensory afference to improvements in clinical pain, and the specific brain circuits involved.

Methods: In this open-label, single-arm, investigator-initiated trial (ClinicalTrials.gov NCT01650376), patients with high-grade serous ovarian cancer who failed primary platinum and taxane therapy received oral olaparib tablets twice daily days 1-3 each week combined with fixed-dose metronomic carboplatin AUC2 and paclitaxel 60 mg/m weekly for 3 out of 4 weeks.
Background: Medical student clinical confidence and positive attitudes to patient centredness are important outcomes of medical education. The clinical placement setting is regarded as a critical support to these outcomes, so understanding how the setting is influential is important. The aim of this study was to compare students' attitudes towards patient-centredness and clinical confidence as they progressed through their medical course, and understand the influence of diverse clinical placement zones.

In metastatic melanoma, this approach results in measurable albeit modest clinical responses in patients resistant to conventional therapy. We reasoned that concurrent cytotoxic T-cell lymphocyte antigen-4 (CTLA-4) checkpoint blockade might enhance the antitumor activity of adoptively transferred CTLs.
View Article and Find Full Text PDFAdoptive transfer of peripheral blood-derived, melanoma-reactive CD8(+) cytotoxic T lymphocytes (CTLs) alone is generally insufficient to eliminate bulky tumors. Similarly, monotherapy with anti-CTLA4 infrequently yields sustained remissions in patients with metastatic melanoma. We postulated that a bolus of enhanced IL-21-primed polyclonal antigen-specific CTL combined with CTLA4 blockade might boost antitumor efficacy.

An evolutionary approach to social cognition implies that proximate mating motives may lead people to display desirable mental traits. In signaling such traits, one can increase the likelihood of attracting a potential mate.

In p53-deficient cells in which the G1-S checkpoint is compromised, cell viability after DNA damage relies upon intact intra-S and G2-M checkpoints mediated by the ATR (ataxia telangiectasia and Rad3 related) and Chk1 kinases. Thus, a logical rationale to sensitize p53-deficient cancers to DNA-damaging chemotherapy is through the use of ATP-competitive inhibitors of ATR or Chk1.

Several immune evasion mechanisms are active in MCC including down-regulation of HLA class-I expression on tumor cells and dysfunctional endogenous MCPyV-specific CD8 T cell responses. To overcome these obstacles, we combined local and systemic immune therapies in a 67-year-old man, who developed metastatic MCPyV-expressing MCC.

We report herein the successful optimisation of the pharmacokinetic (PK) properties to afford the potent, selective, orally bioavailable and CNS penetrant compound 15f. A custom optimisation approach was required which demonstrated the value of using early, rapid in vivo PK studies to show improvements in oral exposure.

However, our understanding of the processes underlying this neurovascular coupling remains incomplete and, particularly, how these vary across the brain. Recent work supports an important role for astrocytes in neurovascular coupling, in large part via activation of their metabotropic glutamate receptors (mGluR).

However, interventions that fail to recruit socio-economically representative samples may widen existing health inequalities. This paper explores the barriers and facilitators to engaging a socio-economically disadvantaged (SED) population in primary prevention for coronary heart disease (CHD).

No systematic study has been conducted on the effect of the combination of nitrous oxide with a potent inhalational agent such as isoflurane on sensory evoked responses.
Methods: Median nerve somatosensory evoked responses from the cervical and cortical regions (SSEP), auditory brainstem responses (ABR) and flash visual evoked responses (VEP) were tested in baboons.
The hippocampus is thought to be involved in a range of cognitive processes, from the ability to acquire new memories, to the ability to learn about spatial relationships. Humans and monkeys with damage to the hippocampus are typically impaired on delayed matching to sample tasks, of which the operant delayed matching to position task (DMTP) is a rat analogue. The reported effects of hippocampal damage on DMTP vary, ranging from delay-dependent deficits to no deficit whatsoever.
View Article and Find Full Text PDFThe hippocampus and prefrontal cortex have both been implicated in various aspects of the acquisition, retention and performance of delayed matching to position (DMTP) tasks in the rat, although their precise respective contributions remain unclear. In the present study, rats were trained preoperatively on DMTP before receiving excitotoxic bilateral lesions of either the entire hippocampus or the medial prefrontal cortex. Rats with lesions of the prefrontal cortex exhibited a significant delay-dependent impairment on retention of the DMTP task, whereas hippocampal lesions were without effect.

This study developed and tested the Foot Care Confidence Scale (FCCS), an instrument designed to measure the confidence (self-efficacy) diabetics have in performing foot self care. Content validity was assessed using Lynn's (1986) Content Validity Index (CVI) with a total of 100% content validity (Sloan, 1993). The FCCS was administered to four persons with diabetes (Sloan, 1994) and pilot tested with 41 healthy older adults (Wills & Sloan, 1995).
