Underlying Event measurements in pp collisions at root s=0.9 and 7 TeV with the ALICE experiment at the LHC

We present measurements of Underlying Event observables in pp collisions at root s = 0 : 9 and 7 TeV. The analysis is performed as a function of the highest charged-particle transverse momentum p(T),L-T in the event. Different regions are defined with respect to the azimuthal direction of the leading (highest transverse momentum) track: Toward, Transverse and Away. The Toward and Away regions collect the fragmentation products of the hardest partonic interaction. The Transverse region is expected to be most sensitive to the Underlying Event activity. The study is performed with charged particles above three different p(T) thresholds: 0.15, 0.5 and 1.0 GeV/c. In the Transverse region we observe an increase in the multiplicity of a factor 2-3 between the lower and higher collision energies, depending on the track p(T) threshold considered. Data are compared to PYTHIA 6.4, PYTHIA 8.1 and PHOJET. On average, all models considered underestimate the multiplicity and summed p(T) in the Transverse region by about 10-30%.

Measurement of prompt J/psi and beauty hadron production cross sections at mid-rapidity in pp collisions at root s=7 TeV

The ALICE experiment at the LHC has studied J/psi production at mid-rapidity in pp collisions at root s = 7 TeV through its electron pair decay on a data sample corresponding to an integrated luminosity L-int = 5.6 nb(-1). The fraction of J/psi from the decay of long-lived beauty hadrons was determined for J/psi candidates with transverse momentum p(t) > 1,3 GeV/c and rapidity vertical bar y vertical bar < 0.9. The cross section for prompt J/psi mesons, i.e. directly produced J/psi and prompt decays of heavier charmonium states such as the psi(2S) and chi(c) resonances, is sigma(prompt J/psi) (p(t) > 1.3 GeV/c, vertical bar y vertical bar < 0.9) = 8.3 +/- 0.8(stat.) +/- 1.1 (syst.)(-1.4)(+1.5) (syst. pol.) mu b. The cross section for the production of b-hadrons decaying to J/psi with p(t) > 1.3 GeV/c and vertical bar y vertical bar < 0.9 is a sigma(J/psi <- hB) (p(t) > 1.3 GeV/c, vertical bar y vertical bar < 0.9) = 1.46 +/- 0.38 (stat.)(-0.32)(+0.26) (syst.) mu b. The results are compared to QCD model predictions. The shape of the p(t) and y distributions of b-quarks predicted by perturbative QCD model calculations are used to extrapolate the measured cross section to derive the b (b) over bar pair total cross section and d sigma/dy at mid-rapidity.

Synthesis and properties of heterobifunctional photoaffinity reagents for the identification and isolation of receptors

A method employing isotopically- and photoaffinity-labeled probes and polyclonal and monoclonal antibody to the probes for the identification, isolation and recovery of protein receptors is described. Antibody was raised against N-(3-(p-azido-m-($\sp{125}$I) -iodophenyl)) propionate (AIPP) coupled to and photolyzed to BSA. The antibodies specifically bound AIPP-derivatized proteins. An isolation system was developed utilizing this probe and two antigenically identical reversible analogues. N-(3-((p-azido-m-($\sp{125}$I) -iodo-phenyl)propionyl)amidoethyl-1,3-dithiopropionyl) succinimide (Reversible $\sp{125}$I-AIPPS) reacts with primary amines and N-(((3-p-azido-m-($\sp{125}$I) -iodophenyl)propionyl)amidoethyl)dithiopyridine ($\sp{125}$I-AIPP-PDA) reacts with reduced thiols. The applicability of the system was established by derivatizing known ligands (Transferrin and Interferon-alpha) with one of the probes. The ligand-probe was then allowed to interact with its receptor by incubation with SS5 lymphoma cells and cross-linked by photolysis at 300 nm. The photolyzed ligand/probe/receptor preparation was then recovered with AIPP antibody. Utilization of N-(3-((p-azido-m-($\sp{125}$I) -iodo-phenyl-propionyl)-amidoethyl-1,3-dithiopropionyl) succinimide (Reversible $\sp{125}$I-AIPPS) allowed the components of the photolyzed complex to be separated by treatment with 2-mercaptoethanol in the SDS-PAGE solubilization buffer. Ligand and receptor labeling were then assessed by Coomassie staining and autoradiography. Results of receptor assays suggest that $\sp{125}$I-AIPP was, indeed, transferred to moieties that represent the receptors for both Transferrin and Interferon-alpha. ^

THE LONG-TERM GROWTH OF NORMAL HUMAN B CELLS

The feasibility of establishment of continuously proliferating growth factor-dependent human B lymphocytes was investigated. Normal B lymphocytes prepared from peripheral venous blood were stimulated with a variety of known polyclonal B cell activators, in the continuous presence of various cytokine preparations. Continuously proliferating growth factor-dependent B cell populations were obtained from cultures activated with either insoluble anti-IgM ((mu)-chain specific), soluble anti-IgM, heat-killed Staphylococcus aureus Cowen I (SAC), or dextran sulphate (DxS), in the continuous presence of exogenously added growth factor preparations containing either IL-1, IL-2 and BCGF, or BCGF alone. Although growth factor-dependent B cell lines were obtained via all three methods of activation, the correlation of mode of activation and growth factor preparation proved to be critical. B cell lines could not be established with anti-(mu) activation in the presence of only BCGF; however, B cell lines were successfully obtained with SAC or DxS activation from those cultures continuously replenished with only BCGF. These cultured B lymphocyte populations were routinely maintained in logarithmic-phase growth in the presence of exogenously added growth factor, and exhibited a population doubling time of approximately 36 hours. They were shown to specifically absorb BCGF, suggesting the presence of membrane receptors for it. Also, these cultured B cells have been utilized for the development of a microassay for the assessment of a M(,r) 12,000-14,000 B cell growth factor activity that is accurate, sensitive, and precise. The pronounced sensitivity of this bioassay beyond that of the conventional peripheral blood B cell assay has aided in the purification to homogeneity of natural product extracellular BCGF (EC-BCGF), and in the determination of the nucleotide sequence for a gene coding for a protein exhibiting BCGF activity. Additionally, these B cell lines specifically absorb, and proliferate in the presence of, an affinity-purified M(,r) 60,000 trypsin-sensitive intracellular protein derived from freshly isolated human T lymphocytes, providing evidence for a putative intracellular precursor of EC-BCGF, or a novel high molecular weight BCGF species. ^

THE EFFECT OF GABAMIMETICS ON NEUROTRANSMITTER RECEPTOR BINDING AND FUNCTION IN RAT BRAIN

Gamma-aminobutyric acid (GABA) is a major inhibitory neurotransmitter in the central nervous system and alterations in central GABAergic transmission may contribute to the symptoms of a number of neurological and psychiatric disorders. Because of this relationship, numerous laboratories are attempting to develop agents which will selectively enhance GABA neurotransmission in brain. Due to these efforts, several promising compounds have recently been discovered. Should these drugs prove to be clinically effective, they will be used to treat chronic neuropsychiatric disabilities and, therefore, will be administered for long periods of time. Accordingly, the present investigation was undertaken to determine the neurochemical consequences of chronic activation of brain GABA systems in order to better define the therapeutic potential and possible side-effect liability of GABAmimetic compounds.^ Chronic (15 day) administration to rats of low doses of amino-oxyacetic acid (AOAA, 10 mg/kg, once daily), isonicotinic acid hydrazide (20 mg/kg, b.i.d.), two non-specific inhibitors of GABA-T, the enzyme which catabolizes GABA in brain, or (gamma)-acetylenic GABA (10 mg/kg, b.i.d.) a catalytic inhibitor of this enzyme, resulted in a significant elevation of brain and CSF GABA content throughout the course of treatment. In addition, chronic administration of these drugs, as well as the direct acting GABA receptor agonists THIP (8 mg/kg, b.i.d.) or kojic amine (18 mg/kg, b.i.d.) resulted in a significant increase in dopamine receptor number and a significant decrease in GABA receptor number in the corpus striatum of treated animals as determined by standard in vitro receptor binding techniques. Changes in the GABA receptor were limited to the corpus striatum and occurred more rapidly than did alterations in the dopamine receptor. The finding that dopamine-mediated stereotypic behavior was enhanced in animals treated chronically with AOAA suggested that the receptor binding changes noted in vitro have some functional consequence in vitro.^ Coadministration of atropine (a muscarinic cholinergic receptor antagonist) blocked the GABA-T inhibitor-induced increase in striatal dopamine receptors but was without effect on receptor alterations seen following chronic administration of direct acting GABA receptor agonists. Atropine administration failed to influence the drug-induced decreases in striatal GABA receptors.^ Other findings included the discovery that synaptosomal high affinity ('3)H-choline uptake, an index of cholinergic neuronal activity, was significantly increased in the corpus striatum of animals treated acutely, but not chronically, with GABAmimetics.^ It is suggested that the dopamine receptor supersensitivity observed in the corpus striatum of animals following long-term treatment with GABAmimetics is a result of the chronic inhibition of the nigrostriatal dopamine system by these drugs. Changes in the GABA receptor, on the other hand, are more likely due to a homospecific regulation of these receptors. An hypothesis based on the different sites of action of GABA-T inhibitors vis-a-vis the direct acting GABA receptor agonists is proposed to account for the differential effect of atropine on the response to these drugs.^ The results of this investigation provide new insights into the functional interrelationships that exist in the basal ganglia and suggest that chronic treatment with GABAmimetics may produce extrapyramidal side-effects in man. In addition, the constellation of neurochemical changes observed following administration of these drugs may be a useful guide for determining the GABAmimetic properties of neuropharmacological agents. ^

Distribution of quality adjusted life expectancy: A systems approach

Statistical methods are developed which assess survival data for two attributes; (1) prolongation of life, (2) quality of life. Health state transition probabilities correspond to prolongation of life and are modeled as a discrete-time semi-Markov process. Imbedded within the sojourn time of a particular health state are the quality of life transitions. They reflect events which differentiate perceptions of pain and suffering over a fixed time period. Quality of life transition probabilities are derived from the assumptions of a simple Markov process. These probabilities depend on the health state currently occupied and the next health state to which a transition is made. Utilizing the two forms of attributes the model has the capability to estimate the distribution of expected quality adjusted life years (in addition to the distribution of expected survival times). The expected quality of life can also be estimated within the health state sojourn time making more flexible the assessment of utility preferences. The methods are demonstrated on a subset of follow-up data from the Beta Blocker Heart Attack Trial (BHAT). This model contains the structure necessary to make inferences when assessing a general survival problem with a two dimensional outcome. ^

"Our Father Isaac": Reading the Sahidic Testament of Isaac in an Egyptian Monastic Context

This dissertation argues that the textual community of fourth or fifth century monastic Egypt read Testament of Isaac as an ascetical regimen in order to transform themselves into children of Isaac. T. Isaac highlights three particular dimensions of Isaac's character from the remembered tradition of Isaac that would have resonated in the Egyptian monastic context of the textual community - Isaac as priestly authority, Isaac as sacrifice, and Isaac as blind ascetic - to create a model for the new self that the textual community aimed to achieve. Two important ascetic practices in T. Isaac that the textual community was to perform were copying and reading T. Isaac. These two practices functioned as technologies of the self that helped the members of the textual community to transform their present subjectivity into a new self modeled on Isaac in T. Isaac.

Records of the Geographical Society, ca. 1796

This small blue-covered paper notebook contains four leaves with the handwritten records of the Geographical Society, an undergraduate organization at Harvard in the late 1790s. The records consist of ten handwritten "Laws of the Geographical Society" and a short list of fines dispensed on October 7th. A list of six student surnames is written on a scrap of paper and attached with pins to the notebook's inside front cover. The surnames likely correspond to six members of the Harvard Class of 1798: John Abbot (1777-1854), Isaac Adams (d. 1807), Francis Brigham (d. November 14, 1796), Humphrey Devereux (1779-1867), Joseph Emerson (1777-1833), and Artemas Sawyer (d. 1826). The notebook is undated but was presumably kept in 1795 or 1796 around the time of Brigham's death on November 14, 1796. While Brigham's surname appears in the list of fines, it is crossed out on the inside front cover.
