Abstract
Light probes interacting with heavy bound states such as black holes give rise to observables containing valuable dynamical information. Recently, a family of black hole microstates was shown to admit an exact string worldsheet description. We construct the physical vertex operators of these models, and compute an extensive set of novel heavy-light correlators. We then obtain the first match between worldsheet correlators in black hole microstates and the holographically dual conformal field theory. We conjecture a closed formula for correlators with an arbitrary number of light insertions. As an application, we compute the analogue of the Hawking radiation rate for these microstates.

Abstract
Trifluoromethyl groups are widespread in medicinal chemistry, yet there are limited 18F-radiochemistry techniques available for the production of the complementary PET agents. Herein, we report the first radiosynthesis of the anticancer nucleoside analogue trifluridine, using a fully automated, clinically-applicable 18F-trifluoromethylation procedure. [18F]Trifluridine was obtained after two synthetic steps in <2 hours. The isolated radiochemical yield was 3% ± 0.44 (n = 5), with a radiochemical purity >99%, and a molar activity of 0.4 GBq μmol-1 ± 0.05. Biodistribution and PET-imaging data using HCT116 tumour-bearing mice showed a 2.5 %ID g-1 tumour uptake of [18F]trifluridine at 60 minutes post-injection, with bone uptake becoming a prominent feature thereafter. In vivo metabolite analysis of selected tissues revealed the presence of the original radiolabelled nucleoside analogue, together with deglycosylated and phosphorylated [18F]trifluridine as the main metabolites. Our findings suggest a potential role for [18F]trifluridine as a PET radiotracer for elucidation of drug mechanism of action.

Abstract
We construct the first family of horizonless supergravity solutions that have the same mass, charges, and angular momenta as general supersymmetric rotating D1-D5-P black holes in five dimensions. This family includes solutions with arbitrarily small angular momenta, deep within the regime of quantum numbers and couplings for which a large classical black hole exists. These geometries are well approximated by the black-hole solution, and in particular exhibit the same near-horizon throat. Deep in this throat, the black-hole singularity is resolved into a smooth cap. We also identify the holographically dual states in the N=(4,4) D1-D5 orbifold conformal field theory (CFT). Our solutions are among the states counted by the CFT elliptic genus, and provide examples of smooth microstate geometries within the ensemble of supersymmetric black-hole microstates.

Abstract
BACKGROUND Sun exposure is associated with several ophthalmic diseases, including pterygium which may develop in adolescence. This study reports the prevalence of pterygium and its associations in a large cohort of young Australian adults. Conjunctival ultraviolet autofluorescence, a biomarker of ocular sun exposure, has recently been characterized in some Australian populations. DESIGN Cross-sectional population-based study. PARTICIPANTS One thousand three hundred forty-four subjects aged 18-22 years in the Western Australian Pregnancy Cohort (Raine) Study. METHODS Standardized colour and ultraviolet autofluorescence photographs of the nasal and temporal conjunctiva were taken, and assessed for presence of pterygium and area of autofluorescence. Sun exposure and protective factors were assessed by structured questionnaire. MAIN OUTCOME MEASURES Area of conjunctival ultraviolet autofluorescence in square millimetre (mm(2)) and presence of pterygium. RESULTS Median total conjunctival autofluorescence was 44.2 mm(2) (interquartile range 20.2-69.8 mm(2)). Median conjunctival autofluorescence was higher in nasal than in temporal quadrants (23.8 mm(2) vs. 18.9 mm(2), P < 0.001), but did not differ according to age or gender. Higher body mass index was associated with lower levels of autofluorescence. Total autofluorescence increased with increasing time spent outdoors. Prevalence of pterygium was 1.2% (95% confidence interval 0.6-1.8%), and was associated with male gender (odds ratio 6.71, P = 0.012). Participants with pterygium had significantly more conjunctival autofluorescence than those without (median 73.4 mm(2) vs. 44.0 mm(2), P = 0.001). CONCLUSIONS Conjunctival ultraviolet autofluorescence is associated with increased time spent outdoors, and increased prevalence of pterygium. The association of this biomarker with other ophthalmohelioses, including cataract, ocular surface squamous neoplasia and eyelid malignancy, has yet to be determined.

Abstract
The first transition-metal complex-based two-photon absorbing luminescence lifetime probes for cellular DNA are presented. This allows cell imaging of DNA free from endogenous fluorophores and potentially facilitates deep tissue imaging. In this initial study, ruthenium(II) luminophores are used as phosphorescent lifetime imaging microscopy (PLIM) probes for nuclear DNA in both live and fixed cells. The DNA-bound probes display characteristic emission lifetimes of more than 160 ns, while shorter-lived cytoplasmic emission is also observed. These timescales are orders of magnitude longer than conventional FLIM, leading to previously unattainable levels of sensitivity, and autofluorescence-free imaging.

Abstract
INTRODUCTION Choline radiotracers are widely used for clinical PET diagnosis in oncology. [(11)C]Choline finds particular utility in the imaging of brain and prostate tumor metabolic status, where 2-[(18)F]fluoro-2-deoxy-D-glucose ('FDG') shows high background uptake. More recently we have extended the clinical utility of [(11)C]choline to breast cancer where radiotracer uptake correlates with tumor aggressiveness (grade). In the present study, a new choline analog, [(18)F]fluoro-[1,2-(2)H(4)]choline, was synthesized and evaluated as a potential PET imaging probe. METHODS [(18)F]Fluorocholine, [(18)F]fluoro-[1-(2)H(2)]choline and [(18)F]fluoro-[1,2-(2)H(4)]choline were synthesized by alkylation of the relevant precursor with [(18)F]fluorobromomethane or [(18)F]fluoromethyl tosylate. Radiosynthesis of [(18)F]fluoromethyl tosylate required extensive modification of the existing method. [(18)F]Fluorocholine and [(18)F]fluoro-[1,2-(2)H(4)]choline were then subjected to in vitro oxidative stability analysis in a chemical oxidation model using potassium permanganate and an enzymatic model using choline oxidase. The two radiotracers, together with the corresponding di-deuterated compound, [(18)F]fluoro-[1-(2)H(2)]choline, were then evaluated in vivo in a time-course biodistribution study in HCT-116 tumor-bearing mice. RESULTS Alkylation with [(18)F]fluoromethyl tosylate proved to be the most reliable radiosynthetic route. Stability models indicate that [(18)F]fluoro-[1,2-(2)H(4)]choline possesses increased chemical and enzymatic (choline oxidase) oxidative stability relative to [(18)F]fluorocholine. The distribution of the three radiotracers, [(18)F]fluorocholine, [(18)F]fluoro-[1-(2)H(2)]choline and [(18)F]fluoro-[1,2-(2)H(4)]choline, showed a similar uptake profile in most organs. Crucially, tumor uptake of [(18)F]fluoro-[1,2-(2)H(4)]choline was significantly increased at late time points compared to [(18)F]fluorocholine and [(18)F]fluoro-[1-(2)H(2)]choline. CONCLUSIONS Stability analysis and biodistribution suggest that [(18)F]fluoro-[1,2-(2)H(4)]choline warrants further in vivo investigation as a PET probe of choline metabolism.

Abstract
AIM To determine if human papillomaviruses (HPVs) play a role in the histogenesis of adenosarcomas of the uterine cervix. METHODS Nine archival cases of primary cervical adenosarcoma were studied. The HPV status of the nine histologically proven tumours was investigated by non-isotopic in situ hybridisation (NISH) and PCR. NISH was performed using digoxigenin labelled probes to HPV types 6, 11, 16, 18, 31 and 33. PCR used GP5+/GP6+ primers to the HPV L1 gene. RESULTS Neither the benign epithelial components nor the malignant stromal components of the 9 neoplasms harboured nuclear NISH signals for the HPV types investigated. Amplimers of the HPV L1 gene were not detected by PCR in any of the tumours studied. CONCLUSION HPVs do not appear to play an aetiological role in cervical adenosarcomas. This suggests that a different histogenetic pathway for this rare tumour type must exist.

Abstract
UNLABELLED The integrin alpha v beta3 receptor is upregulated on tumor cells and endothelium and plays important roles in angiogenesis and metastasis. Arg-Gly-Asp (RGD) peptide ligands have high affinity for these integrins and can be radiolabeled for PET imaging of angiogenesis or tumor development. We have assessed the safety, stability, and tumor distribution kinetics of a novel radiolabeled RGD-based integrin peptide-polymer conjugate, 18F-AH111585, and its feasibility to detect tumors in metastatic breast cancer patients using PET. METHODS The biodistribution of 18F-AH111585 was assessed in 18 tumor lesions from 7 patients with metastatic breast cancer by PET, and the PET data were compared with CT results. The metabolic stability of 18F-AH111585 was assessed by chromatography of plasma samples. Regions of interest (ROIs) defined over tumor and normal tissues of the PET images were used to determine the kinetics of radioligand binding in tissues. RESULTS The radiopharmaceutical and PET procedures were well tolerated in all patients. All 18 tumors detected by CT were visible on the 18F-AH111585 PET images, either as distinct increases in uptake compared with the surrounding normal tissue or, in the case of liver metastases, as regions of deficit uptake because of the high background activity in normal liver tissue. 18F-AH111585 was either homogeneously distributed in the tumors or appeared within the tumor rim, consistent with the pattern of viable peripheral tumor and central necrosis often seen in association with angiogenesis. Increased uptake compared with background (P = 0.002) was demonstrated in metastases in lung, pleura, bone, lymph node, and primary tumor. CONCLUSION 18F-AH111585 designed to bind the alpha v beta3 integrin is safe, metabolically stable, and retained in tumor tissues and detects breast cancer lesions by PET in most anatomic sites.

Abstract
2-Acetyl-1-(4'-chlorophenyl)-6,7-dimethoxy-1,2,3,4-tetrahydroisoquinoline, one of the most potent non-competitive AMPA antagonists described to date, has been labelled with carbon-11 and tritium and evaluated as a potential ligand for in vivo imaging of AMPA receptors using PET. The carbon-11 labelled compound showed good initial brain uptake in rats, but with rapid clearance and relatively homogenous distribution. In saturation binding studies, the tritiated racemic ligand was found to be highly potent with a Kd of 14.8+/-1.8 nM. We conclude that the low receptor density labelled with this compound, its rapid clearance from the CNS and low specific binding makes it unsuitable as an in vivo PET imaging agent for AMPA receptors.

Abstract
Usual causes of intolerance to thyroxine sodium include coronary artery disease, advanced age, untreated adrenal insufficiency, and severe hypothyroidism. We describe 4 patients with iron deficiency anemia and primary hypothyroidism. After treatment with thyroxine sodium, these patients developed palpitations and feelings of restlessness, which necessitated discontinuation of the thyroid hormone. After the anemia was treated with ferrous sulfate for 4 to 7 weeks, they were able to tolerate thyroxine sodium therapy. Iron deficiency anemia coexisting with primary hypothyroidism results in a hyperadrenergic state. In such patients, we postulate that thyroid hormone administration causes palpitations, nervousness, and feelings of restlessness. Correction of any existing pronounced anemia in hypothyroid patients who are intolerant to thyroxine sodium therapy may result in tolerance to this agent.

Abstract
The Mursi are a small group of herders and cultivators living in the Lower Omo Valley of southwestern Ethiopia. Over the past 20 years they have suffered a disaster of classic proportions, involving drought, famine, migration and war. Measures taken to ensure the physical survival of people, and especially cattle, in the face of regular and expected attacks by their neighbours have made the economy of the Mursi more vulnerable to climatic uncertainty. A crude materialist explanation of warfare is not, therefore, supported by this case but it is clear also that warfare has played a key part in Mursi expansion northwards, over the past century, into the territory of the Bodi. Warfare, in this context, is a means of establishing and maintaining the separate political identities of neighbouring groups. The problem of survival does not present itself to the Mursi and their neighbours as a choice between political and physical survival: the only way they know of saving lives is to save their way of life.

Abstract
A tracer kinetic procedure was developed for the measurement of monoamine oxidase type B (MAO-B) activity using L-[11C]deprenyl and positron emission tomography (PET). The kinetic model consisted of two tissue compartments with irreversible binding to the second compartment (three rate constants). In addition, a blood volume component was included. Special attention was given to the accurate measurement of the plasma and whole blood input functions. The method was applied to the measurement of the dose-response curve of a reversible MAO-B inhibitor (Ro 19-6327). From the results, it followed that the rate constant for irreversible binding (k3) appeared to be a better index of MAO-B activity than the net influx constant Ki. Furthermore, regional analysis demonstrated that Ki, but not k3, was flow dependent. This implies that full kinetic analysis is required for an accurate assessment of MAO-B activity.

Abstract
Eight normal subjects (3 females and 5 males) were studied using intravenous L-[11C] deprenyl and positron emission tomography. In a single blind study one subject received tracer alone, one subject received an oral pre-dose of 20 mg of L-deprenyl and 6 subjects received oral pre-doses of 10 to 50 mg of a novel reversible MAO-B inhibitor (Ro 19-6327). Dynamic PET scans beginning 12 h after the oral dose were collected over 90 min and arterial blood was continuously sampled. Data analysis was modelled for two tissue compartments and using an iterative curve fitting technique the value of the rate constant for irreversible binding of L-[11C] deprenyl to MAO-B (k3) in whole brain was obtained for each subject. The dose response curves obtained indicated that a dose of at least 0.48 mg.kg-1 of Ro 19-6327 was necessary for greater than 90% decrease in whole brain k3. Inhibition of MAO-B in platelets isolated from blood samples taken at the time of scanning correlated strongly with decrease in whole brain k3 (r = 0.949). The results indicate that PET can be used to determine the dose of Ro 19-6327 necessary to inhibit greater than 90% of brain MAO-B. This technique is an attractive alternative to traditional large scale patient-based dose-finding studies. Moreover it is shown that inhibition of platelet MAO-B can be used as a marker for central MAO-B inhibition with Ro 19-6327.

Abstract
A total of 210 breast milk samples from 5 different regions across Canada were analyzed for polychlorinated biphenyls (PCBs), hexachloro-1,3-butadiene, ten chlorinated benzenes, two chlorinated naphthalenes, Mirex, photomirex, alpha, beta and gamma hexachlorocyclohexane, alpha and gamma chlordane, oxychlordane, trans-nonachlor, p,p'-DDT and some analogs, heptachlor epoxide, dieldrin and octachlorostyrene. There was no evidence for the presence of hexachloro-1,3-butadiene, Mirex, octachlorostyrene, chlorinated naphthalenes or tetrachlorobenzenes in the breast milk. Residues of other compounds were found in all samples, except 1,2-dichlorobenzene, gamma hexachlorocyclohexane, alpha and gamma chlordane and p,p'-TDE, which were less frequently observed, while o,p'-DDT was only found in approximately one quarter of all samples. Since 1967, a steady decline in heptachlor epoxide, dieldrin and p,p'-DDT and related residues is apparent. At the same time however, there is an apparent increase in PCB residue levels since 1970. This apparent increase should be viewed with some caution, since much of this increase might be attributed to better sampling and analytical techniques. Residue levels of breast milk in Canada were similar to those found in other industrial nations. Regional differences in residue levels appeared to be minimal.

Abstract
Use of radiolabeled microspheres is a standard method to measure regional myocardial perfusion in animals. Human albumin microspheres have been given safely to patients, but positron-emitting 68Ga-labeled human albumin microspheres are characterized by an unstable radiolabel. A new labeling procedure that covalently binds 11C (t1/2 = 20.3 min) to human albumin microspheres via 11CH3I was developed. Seven open-chest and two closed-chest dogs were studied. Reference and 11C-labeled human albumin microspheres (2 to 25 mCi) were both injected into the left atrium. Positron tomographic images were obtained of the myocardial distribution of the 11C-labeled microspheres. Timed arterial withdrawal was used for both reference gamma-labeled microspheres and 11C-labeled human albumin microspheres. Myocardial tissue samples matched to tomographic slices were well-counted for calculation of reference values of regional myocardial perfusion. Serial venous blood samples for residual 11C activity of 30 and 60 min after injection were less than 1% of the myocardial 11C concentration demonstrating a stable 11C bond to the human albumin microspheres. Regional myocardial perfusion calculated by this technique correlated well with values obtained with reference microspheres (r = .97) over a range of 0.2 to 3.5 ml/min/g. Correction for wall thickness improved the slope of the regression equation from y = 0.71 x -0.03 to y = 0.88 X -0.05. Thus, 11C human albumin microspheres are stable radiochemically and can be used as a quantitative measure of regional myocardial perfusion.

Abstract
Based upon two recent periods of fieldwork among a spontaneously resettled population of cattle herders in southwestern Ethiopia, this paper is an attempt to illustrate, by a particular case, the general proposition that external aid, if it is not to be counter-productive, must meet people's needs as they themselves define them. The people in question, the Mursi, have experienced, since 1970, their worst period of drought and hunger in living memory. They have responded to this experience with resilience and inventiveness and largely without external assistance. The paper concentrates on a recent, drought induced, migration of Mursi to higher land, outside their traditional territory, and shows how the migrants are adapting to a new way of life which brings them into direct conflict with some of their most cherished cultural traditions.
