INTRODUCTION    Shorter leukocyte telomere length (TL) is associated with several chronic diseases, but only a few studies have assessed the associations of dietary components and dietary patterns with TL in adults in the United States (US). OBJECTIVES    This study was aimed to determine the relation of dietary components and dietary patterns with TL among adults in the US. PATIENTS AND METHOD...

The trophic level (TL) mean and variance, and the degree of omnivory for five Celtic Sea fish predators were estimated using a database of stomach content records characterized by a high level of taxonomic resolution. The predators occupied a high position in the food web, i.e. 4·75 for Atlantic cod Gadus morhua, 4·44 for haddock Melanogrammus aeglefinus, 4·88 for European hake Merluccius merlu...

In regular inference, a regular language is inferred from answers to a finite set of membership queries, each of which asks whether the language contains a certain word. One of the most well-known regular inference algorithms is the L∗ algorithm due to Dana Angluin. However, there are almost no extensions of these algorithms to the setting of timed systems. We extend Angluin’s algorithm for on-...

beryllium  oxide  (beo)  nanopowder  was  synthesized  using  sol-gel method  and  the  effects  of  changes of  chemical  reagents  were investigated.  because  of  tissue  equivalence  and  other  outstanding thermoluminescence  (tl) properties of  the bulk material  in x and γ dosimetry, the applicability of this nanostructure in tl dosimetry was studied  following  irradiation to  the 137 c...

thirty one patients with biologic and clinical diagnosis of hyperparathyroidism were submitted to thalium-technetium scan prior to exploration of the neck. scan findings were compared with the pathologic results. surgical exploration of the neck showed a parathyroid adenoma in 24 patients, parathyroid carcinoma in one patient, normal parathyroid in another patient and parathyroid hyperplasia in...

BACKGROUND Shortening of mean telomere length (TL) in white blood cells is correlated with the development of coronary heart disease (CHD) and with increased mortality due to infectious disease. The goal of the present study was to investigate whether telomere shortening in CHD is restricted to specific peripheral blood lymphocyte and/or myeloid cell subpopulations. Results were correlated to T...

Fructose-1,6-bisphosphatase (Fru-1,6-Pase; D-fructose-1,6-bisphosphate 1-phosphohydrolase, EC 3.1.3.11) requires two divalent metal ions to hydrolyze alpha-D-fructose 1,6-bisphosphate. Although not required for catalysis, monovalent cations modify the enzyme activity; K+ and Tl+ ions are activators, whereas Li+ ions are inhibitors. Their mechanisms of action are still unknown. We report here cr...

BMJ Case Rep Published online: [please include Day Month Year] doi:10.1136/bcr-2014204325 DESCRIPTION A reverse redistribution pattern in rest thallium-201 (Tl)/stress technetium-99 m (Tc) tetrofosmin single photon emission CT (SPECT) is confusing. We present a myocardial perfusion SPECT in a 40-year-old patient undergoing coronary intervention in t...

We have developed a new method of crosstalk correction in simultaneous dual-isotope imaging with Tl-201 and I-123 by using crosstalk ratios and a blurring filter. Single isotope myocardial studies (10 for Tl-201 and 7 for I-123) were performed with a dual energy window acquisition mode and two low energy general-purpose collimators. Then two planar images acquired with dual energy windows for a...
