    The field of pharmacy is changing from a drug-distribution-centered model to a patient-centered integrated model whereby pharmacists are actively involved in patient care as part of an interdisciplinary team. To address the estimated pharmacy leadership crisis in the future and to prepare pharmacists to work in the changing healthcare landscape, national pharmacy organizations such as the American Society of Health-System Pharmacists (ASHP) and the American College of Clinical Pharmacy (ACCP) have stated that postgraduate pharmacy residency should be mandatory by 2020. Past pharmacy research literature has shown that while many factors influence students to pursue a pharmacy residency, there is a lack of understanding about the influence of clinical faculty mentoring on students to pursue a postgraduate residency. This phenomenological study explored pharmacy students’ experiences with clinical faculty mentoring in relation to Professional Year 4 (PY4) students’ decision to pursue a pharmacy residency. The research was conducted utilizing ten students from two Northeastern Schools of Pharmacy. Qualitative data was collected via interviews using semi-structured open-ended questions. Data from the interviews gathered from both sites were merged for data analysis. Results showed the emergence of seven themes with connected elements: (a) type of mentoring relationship, (b) mentoring functions, (c) mentor characteristics, (d) mentee characteristics, (e) time spent with mentor, (f) decision-making, and (g) need for formal mentoring programs. Findings indicated that PY4 students’ decision to pursue a pharmacy residency does relate to clinical faculty mentoring even though the types of influential clinical faculty mentoring experiences varied. Psychosocial mentoring functions were utilized by clinical faculty that provided positive experiences for participants and allowed for transformative growth. Mentor and mentee characteristics were important in supporting the mentoring process. Time spent with mentors could not be quantified and the quality of time spent with mentors was important. The central finding that clinical faculty mentoring does influence students’ decision to pursue a pharmacy residency fills a gap in pharmacy mentoring literature

    The Discovery of Extended Thermal X-ray Emission from PKS 2152-699: Evidence for a `Jet-cloud' Interaction

    A Chandra ACIS-S observation of PKS 2152-699 reveals thermal emission from a diffuse region around the core and a hotspot located 10" northeast from the core. This is the first detection of thermal X-ray radiation on kiloparsec scales from an extragalactic radio source. Two other hotspots located 47" north-northeast and 26" southwest from the core were also detected. Using a Raymond-Smith model, the first hotspot can be characterized with a thermal plasma temperature of 2.6×106\times10^6 K and an electron number density of 0.17 cm−3^{-3}. These values correspond to a cooling time of about 1.6×107\times10^7 yr. In addition, an emission line from the hotspot, possibly Fe xxv, was detected at rest wavelength 10.04\AA. The thermal X-ray emission from the first hotspot is offset from the radio emission but is coincident with optical filaments detected with broadband filters of HST/WFPC2. The best explanation for the X-ray, radio, and optical emission is that of a `jet-cloud' interaction. The diffuse emission around the nucleus of PKS 2152-699 can be modeled as a thermal plasma with a temperature of 1.2×107\times10^7 K and a luminosity of 1.8×1041\times10^{41} erg s−1^{-1}. This emission appears to be asymmetric with a small extension toward Hotspot A, similar to a jet. An optical hotspot (EELR) is seen less than an arcsecond away from this extension in the direction of the core. This indicates that the extension may be caused by the jet interacting with an inner ISM cloud, but entrainment of hot gas is unavoidable. Future observations are discussed.Comment: To appear in the Astrophysical Journal 21 pages, 5 Postscript figures, 1 table, AASTeX v. 5.

    CENP-A Is Dispensable for Mitotic Centromere Function after Initial Centromere/Kinetochore Assembly

    Human centromeres are defined by chromatin containing the histone H3 variant CENP-A assembled onto repetitive alphoid DNA sequences. By inducing rapid, complete degradation of endogenous CENP-A, we now demonstrate that once the first steps of centromere assembly have been completed in G1/S, continued CENP-A binding is not required for maintaining kinetochore attachment to centromeres or for centromere function in the next mitosis. Degradation of CENP-A prior to kinetochore assembly is found to block deposition of CENP-C and CENP-N, but not CENP-T, thereby producing defective kinetochores and failure of chromosome segregation. Without the continuing presence of CENP-A, CENP-B binding to alphoid DNA sequences becomes essential to preserve anchoring of CENP-C and the kinetochore to each centromere. Thus, there is a reciprocal interdependency of CENP-A chromatin and the underlying repetitive centromere DNA sequences bound by CENP-B in the maintenance of human chromosome segregation

    Kinetics and Mechanism of Formation of S-Nitrosocysteine

    The kinetics and mechanism of the nitrosation of cysteine by nitrous acid has been studied in acidic medium. The stoichiometry of the reaction is strictly 1:1, with the formation of one mole of S-nitrosocysteine (CySNO) fromone mole of nitrous acid. Only two nitrosating agents were detected: nitrous acid itself and protonated nitrous acid which is the hydrated form of the nitrosonium cation, NO+. Nitric oxide itself was not detected as a nitrosant. The bimolecular rate constant for the direct nitrosation of cysteine by nitrous acid was determined to be 6.4±1.1 L mol–1 s–1, while nitrosation by the nitrosonium cation has a rate constant of 6.8× 103 L mol–1 s–1. CySNO is short-lived, and decomposes completely to cystine and nitric oxide within 100 s in the presence of micromolar quantities of Cu(II) ions. Since the physiological environment contains many metal ions and metalloenzymes, it is unlikely that CySNO will be an effective carrier of NO.Keywords: Cysteine, Nitric Oxide, Nitrosothio
