Future Exploration of the Outer Heliosphere and Very Local Interstellar Medium by Interstellar Probe.

A detailed overview of the knowledge gaps in our understanding of the heliospheric interaction with the largely unexplored Very Local Interstellar Medium (VLISM) are provided along with predictions of with the scientific discoveries that await. The new measurements required to make progress in this expanding frontier of space physics are discussed and include in-situ plasma and pick-up ion measurements throughout the heliosheath, direct sampling of the VLISM properties such as elemental and isotopic composition, densities, flows, and temperatures of neutral gas, dust and plasma, and remote energetic neutral atom (ENA) and Lyman-alpha (LYA) imaging from vantage points that can uniquely discern the heliospheric shape and bring new information on the interaction with interstellar hydrogen. The implementation of a pragmatic Interstellar Probe mission with a nominal design life to reach 375 Astronomical Units (au) with likely operation out to 550 au are reported as a result of a 4-year NASA funded mission study.

To probe the binding pathway of a selective compound (D089-0563) to c-MYC Pu24 G-quadruplex using free ligand binding simulations and Markov state model analysis.

D089-0563 is a highly promising anti-cancer compound that selectively binds the transcription-silencing G-quadruplex element (Pu27) at the promoter region of the human c-MYC oncogene; however, its binding mechanism remains elusive. The structure of Pu27 is not available due to its polymorphism, but the G-quadruplex structures of its two shorter derivatives in complex with a ligand (Pu24/Phen-DC3 and Pu22/DC-34) are available and show significant structural variance as well as different ligand binding patterns in the 3' region. Because D089-0563 shares the same scaffold as DC34 while having a significantly different scaffold from Phen-DC3, we picked Pu24 instead of Pu22 for this study in order to gain additional ligand binding insight.

Initial results from the New Horizons exploration of 2014 MU, a small Kuiper Belt object.

The Kuiper Belt is a distant region of the outer Solar System. On 1 January 2019, the New Horizons spacecraft flew close to (486958) 2014 MU, a cold classical Kuiper Belt object approximately 30 kilometers in diameter. Such objects have never been substantially heated by the Sun and are therefore well preserved since their formation.

Dopamine D Receptor-Selective Compounds Reveal Structure-Activity Relationships that Engender Agonist Efficacy.

The dopamine D receptor (DR) plays important roles in cognition, attention, and decision making. Novel DR-selective ligands have promise in medication development for neuropsychiatric conditions, including Alzheimer's disease and substance use disorders. To identify new DR-selective ligands, and to understand the molecular determinants of agonist efficacy at DR, we report a series of eighteen novel ligands based on the classical DR agonist A-412997 (1, 2-(4-(pyridin-2-yl)piperidin-1-yl)- N-( m-tolyl)acetamide).

The Pluto system: Initial results from its exploration by New Horizons.

The Pluto system was recently explored by NASA's New Horizons spacecraft, making closest approach on 14 July 2015. Pluto's surface displays diverse landforms, terrain ages, albedos, colors, and composition gradients. Evidence is found for a water-ice crust, geologically young surface units, surface ice convection, wind streaks, volatile transport, and glacial flow.

The 'straight to test' initiative reduces both diagnostic and treatment waiting times for colorectal cancer: outcomes after 2 years.

Aim: This study aimed to determine whether a 'straight to test'(STT) strategy for 2-week wait (2 wk) referrals for suspected colorectal cancer (CRC) reduced the time to diagnosis and treatment for patients with CRC.

Method: Consecutive 2-week referrals for suspected CRC over a period of 2 years from February 2007 were analysed. The times to the first diagnostic test and treatment and the cancers identified were analysed for those going to STT or the outpatient clinic.

Straight to test. Results of a pilot study in a hospital serving an inner city population.

Objective: The main aims of the study were to determine the frequency with which two-week wait (2ww) referrals for colorectal cancer (CRC) could proceed directly to straight to test (STT), and the potential improvement in time to diagnosis.

Method: A telephone interview was attempted in all 2ww referrals not requiring an advocate and under 80 years. Data were assessed according to a test protocol, and where indicated a potential slot for the appropriate investigation was recorded (virtual test).

Visualization of three-dimensional chaos.

Most chaotic mixing experiments have been restricted to two-dimensional, time-periodic flows, and this has shaped advances in theory as well. A prototypical, bounded, three-dimensional flow with a moderate Reynolds number is presented; this system lends itself to detailed experimental observation and allows for high-precision computational inspection. The flow structure, captured by means of cuts with a laser sheet (experimental Poincare section), was visualized with the use of continuously injected fluorescent dye streams and revealed detailed chaotic structures with high-period islands.

An anticoagulant for transport of bovine blood.

Various anticoagulant were assessed in order to develop a transport media for bovine blood which would improve leukocyte stability. The effects of time, disease in the donor and different personnel and laboratory equipment were also tested. The transport media most effective for leukocyte stability was found to be Titriplex IV.

A volume sensor for a pneumatically driven LVAD.

The volume sensor has proven to be a valuable tool in the operation and characterization of our pneumatically driven LVAD. It compensates for the decoupling between driver and LVAD that occurs in pneumatically actuated LVADs due to gas compressibility. Uses to which we have put the volume sensor represent only a small fraction of the potential applications.
