Purpose: To determine if C-Arm computed tomography (CACT) has added diagnostic value in patients suffering from chronic thromboembolic pulmonary hypertension (CTEPH) with a positive mismatch pattern in ventilation/perfusion single photon emission computed tomography (V/Q SPECT). Materials and Methods: 28 patients (23 men, 5 women, 62 ± 18 years) with CTEPH who had undergone SPECT, followed by CACT and right heart catheterization (RHC) were included. Two independent readers reviewed SPECT and CACT. Findings indicating CTEPH and their location (segmental or sub-segmental) were identified (V/Q mismatch in SPECT and vascular pathologies in CACT)...

OBJECTIVE: Lu-DKFZ-PSMA-617, a urea-based compound, binds to the extracellular domain of prostate-specific membrane antigen, thus providing an effective target for the treatment of metastatic castration-resistant prostate cancer (mCRPC). Before its therapeutic use, it is necessary that the radiation dosimetry of this radiopharmaceutical be studied to determine the safe activity that can be administered in patients to prevent haematological, renal and liver toxicity. The present study thus aimed to assess the pharmacokinetics and dosimetry of Lu-DKFZ-PSMA-617 in CRPC patients...

We report on the implementation of a wide-field time-correlated single photon counting (TCSPC) method for fluorescence lifetime imaging (FLIM). It is based on a 40 mm diameter crossed delay line anode detector, where the readout is performed by three standard TCSPC boards. Excitation is performed by a picosecond diode laser with 50 MHz repetition rate. The photon arrival timing is obtained directly from the microchannel plates, with an instrumental response of ∼190 to 230 ps full width at half maximum depending on the position on the photocathode...

New complex-plasma facility, Plasmakristall-4 (PK-4), has been recently commissioned on board the International Space Station. In complex plasmas, the subsystem of μm-sized microparticles immersed in low-pressure weakly ionized gas-discharge plasmas becomes strongly coupled due to the high (10(3)-10(4) e) electric charge on the microparticle surface. The microparticle subsystem of complex plasmas is available for the observation at the kinetic level, which makes complex plasmas appropriate for particle-resolved modeling of classical condensed matter phenomena...

BACKGROUND: Shanghai was considered to be a "capital of opium" in modern China, hence the history of opium in the city has received significant attention. In the Shanghai International Settlement, where Chinese and foreigners lived as neighbours, drugs were considered by the administration as both "trouble maker", and important financial resource. This paper explores how the Shanghai Municipal Council (SMC), the most senior governing body in the settlement, used its position to maximize political and economic profit from the trade and consumption of opium...

BACKGROUND: Compensation for participating in research has been a fundamental element of the research apparatus despite concerns about its impact on incentivising participation. Researchers and research ethics boards acknowledge that compensation may prompt structurally vulnerable populations, such as people who use drugs (PWUD), to engage in research primarily out of financial need. Thus, institutional restrictions around compensation have been implemented. This study explores the ethical implications of compensation practices aimed at 'protecting' structurally vulnerable people living with HIV (PLHIV) who use drugs within the context of individuals' lived realities...

INTRODUCTION: This paper investigates personality traits as potential factors for success in an astronaut selection by comparing personality profiles of unsuccessful and successful astronaut candidates in different phases of the ESA selection procedure. It is further addressed whether personality traits could predict an overall assessment rating at the end of the selection. METHODS: In 2008/2009, ESA performed an astronaut selection with 902 candidates who were either psychologically recommended for mission training (N = 46) or failed in basic aptitude (N = 710) or Assessment Center and interview testing (N = 146)...

PURPOSE: Diffusion-weighted imaging (DWI) and (18) F-fluorodeoxyglucose-positron emission tomography ((18) F-FDG-PET) independently correlate with malignancy in breast cancer, but the relationship between their structural and metabolic metrics is not completely understood. This study spatially correlates diffusion, perfusion, and glucose avidity in breast cancer with simultaneous PET/MR imaging and compares correlations with clinical prognostics. METHODS: In this Health Insurance Portability and Accountability Act-compliant prospective study, with written informed consent and approval of the institutional review board and using simultaneously acquired FDG-PET and DWI, tissue diffusion (Dt ), and perfusion fraction (fp ) from intravoxel incoherent motion (IVIM) analysis were registered to FDG-PET within 14 locally advanced breast cancers...

The County Council's board for new therapies (the NT Council) provides recommendations on the use of new drugs based on the ethical platform of priorities, founded by the Swedish parliament. The Council has formulated a policy that interprets the parliamentary ethical platform and operationalize its need and solidarity principle and cost effectiveness principle in four dimensions. The NT Council weighs the health economic evaluation of the drug and the four dimensions: the severity of the condition, the rarity of the condition, the effect size and the data reliability to determine the willingness to pay level and whether the platform allows a recommendation for using of the drug...
