[Ga]pentixafor for CXCR4 imaging in a PC-3 prostate cancer xenograft model - comparison with [F]FDG PET/CT, MRI and receptor expression.

Purpose: The aim was to characterize the properties of [Ga]Pentixafor as tracer for prostate cancer imaging in a PC-3 prostate cancer xenograft mouse model and to investigate its correlation with [F]FDG PET/CT, magnetic resonance imaging (MRI) and analyses.

Methods: Static [Ga]Pentixafor and [F]FDG PET as well as morphological/ diffusion weighted MRI and H MR spectroscopy was performed. Imaging data were correlated with biodistribution and CXCR4 expression in PC-3 tumors (immunohistochemistry (IHC), mRNA analysis).

Experimental observation of the crystallization of a paired holon state.

An excitation at 201 meV is observed in the doped-hole ladder cuprate Sr14Cu24O41, using ultraviolet resonance Raman scattering with incident light at 3.7 eV polarized along the rungs. The excitation is of charge nature, with a temperature independent excitation energy, and can be understood via an intraladder pair-breaking process.

Human cytomegalovirus DNA level in patients with idiopathic pulmonary fibrosis.

The objectives of the study were to estimate human cytomegalovirus (HCMV) DNA copy number in broncho-alveolar lavage cells, blood leukocytes, and serum of patients with idiopathic pulmonary fibrosis (IPF). The study groups consisted of 16 patients, newly diagnosed with IPF and never treated, (mean age 40.9 +/-11.

[Two cases of bronchial tuberculosis--diagnostic difficulties].

We present two cases of bronchial tuberculosis. The first one, man aged 45, showed diffuse necrotic changes in bronchoscopic picture described histologically as coagulative necrosis. AFB were not found in sputum smear but only in the cultures.

[Broncho-alveolar lavage cells are the most significant reservoir of human cytomegalovirus genome].

The aim of the study is to estimate human cytomegalovirus DNA copy number in different compartments (BAL cells, blood leukocytes, serum) in patients with idiopathic pulmonary fibrosis (IPF). There were 16 patients (mean age 40.87 +/-10.
