This article discusses the value of 18F-fluoro-2-deoxyglucose PET/CT imaging biomarkers in head and neck squamous cell carcinoma. 18F-fluoro-2-deoxyglucose PET/CT is valuable at baseline staging, radiotherapy planning, therapy response assessment and in the follow-up of patients with head and neck squamous cell carcinoma. Maximum and peak standardized uptake value (SUVmax and SUVpeak), metaboli...

In the title mol-ecule, C(17)H(15)FO(2)S, the O atom and the 4-fluoro-phenyl group of the 4-fluoro-phenyl-sulfinyl substituent lie on opposite sides of the benzofuran fragment. The mean planes of the benzofuran and 4-fluoro-phenyl fragments form a dihedral angle of 86.07 (4)°. In the crystal structure, weak inter-molecular C-H⋯O hydrogen bonds link the mol-ecules into centrosymmetric dimers, wh...

Diagnosis of cardiac involvement in sarcoidosis is challenging and usually relies on a combination of clinical findings and imaging abnormalities. The case of a 53-yr-old female is described who presented with ventricular tachycardia and suspected angiosarcoma involving the right atrium and superior vena cava. A combination of magnetic resonance imaging and (18)F-2-fluoro-2-deoxyglucose-positro...

The treatment of woodchuck hepatitis virus infections with 1-(2'-deoxy-2'-fluoro-beta-D-arabinofuranosyl)-5-iodocytosine (FIAC) and 1-(2'-deoxy-2'-fluoro-beta-D-arabinofuranosyl)-5-methyluracil (FMAU), given intraperitoneally, caused complete and permanent decrease of serum virus endogenous DNA polymerase and viral DNA in all treated woodchucks but was associated with severe toxicity. By contra...

Antimicrobial resistance among human pathogens which is not related to veterinary use 6 Mechanism of (fluoro)quinolone resistance and interpretation of susceptibility tests....... 6 Selection for resistance in food borne pathogens when using (fluoro)quinolones in food-MANDATE The Scientific Advisory Group on Antimicrobials (SAGAM) was mandated to give advice to the CVMP on the need to exercise ...

The mol-ecular structure of the title compound, [Fe(C(5)H(5))(C(13)H(4)F(5))], consists of a ferrocenyl group and a 2,3,4,5,6-penta-fluoro-benzene group linked through an ethyne spacer. The crystal packing is dominated by inter-molecular C-H⋯F hydrogen bonds, C-F⋯π inter-actions between the penta-fluoro-benzene groups [F⋯centroid distances = 3.882 (2) and 3.884 (2) Å] and π-π inter-actions betw...

A set of 42 molecules with N-F, O-F, N-Cl, P-F, and As-F bonds has been investigated in the search for potential bond anomalies, which lead to reverse bond length-bond strength (BLBS) relationships. The intrinsic strength of each bond investigated has been determined by the local stretching force constant obtained at the CCSD(T)/aug-cc-pVTZ level of theory. N-F or O-F bond anomalies were found ...

METHODS After injecting 25.6 ± 8.8 MBq (0.7 ± 0.2 mCi) of 18F-Fluoro-L-DOPA intravenously, three static PET scans were acquired at 20, 30, and 40 min post injection in 3-D mode on 10 patients (6 male, 4 female) with congenital hyperinsulinism. Regions of interest (ROIs) were drawn over several organs visible in the reconstructed PET/CT images and time activity curves (TACs) were generated. Resi...

The title structure, 3C(2)H(7)N(4)O(+)·HFPO(3) (-)·FPO(3) (2-)·H(2)O, contains three independent 2-carbamoylguanidinium cations, one fluoro-phospho-nate, one hydrogen fluoro-phospho-nate and one water mol-ecule. There are three different layers in the structure that are nearly perpendicular to the c axis. Each layer contains a cation and the layers differ by the respective presence of the water...
