UNLABELLED The aim of this study was to use gastroesophageal and pulmonary scintigraphy to evaluate the prevalence of gastroesophageal reflux and airway involvement among patients with posterior laryngitis. METHODS The study included a total of 201 patients (131 females, 70 males; age range, 15-77 y; mean age +/- SD, 49 +/- 16 y). All patients had posterior laryngitis documented by laryngosco...

Thiamazole inhibits the thyroid hormone synthesis and does not inactivate existing thyroxine triiodothyronine that circulate in blood. In this paper electrochemical behavior was monitored by cyclic voltammetry on glassy carbon (GC) electrode absence presence of sodium pertechnetate (99mTc). The influence different concentrations without radiopharmaceutical 99mTc, effect number scan cycles, 99mT...

Cerebral amyloid angiopathy (CAA) is characterized by the deposition of amyloid aggregates in the walls of the cerebral vasculature. Recently, the development of molecular imaging probes targeting CAA has been attracting much attention. We previously reported the 99mTc-hydroxamamide (99mTc-Ham) complex with a bivalent benzothiazole scaffold as a binding moiety for amyloid aggregates ([99mTc]BT2...

Visceral leishmaniasis is one of the most important sever diseases in tropical and subtropical countries. In the present study the effects of antimony sulfide nanoparticles on Leishmania infantum in vitro were evaluated. Antimony sulfide NPs (Sb(2)S(5)) were synthesized by biological method from Serratia marcescens bacteria. Then the cytotoxicity effects of different concentrations (5, 10, 25, ...

Oesophageal pH monitoring data are influenced by numerous patient or technique related factors, or both. In this study, data recorded with glass microelectrodes or antimony electrodes, both with external cutaneous Ag/AgCl reference electrodes, connected to two different recording devices are compared. Pearson correlation coefficients regarding the reflux index (% of the investigation time with ...

Pure and natural essential oils of Allium species are primarily used in the food industry, but due to their low yield, production quantities can be difficult achieve thus highly expensive. Due these problems, adulterations a reality this field. The purpose research is develop multi element stable isotope analysis methodology for authentication leek, onion, shallot, chive. Naturalness was achiev...

Background. Topical diagnosis of primary hyperparathyroidism (PHPT) remains an urgent problem due to the high incidence persistence and recurrence after surgical treatment. At preoperative stage, a search for parathyroid hormone hyperproduction source is performed using instrumental methods: ultrasound, scintigraphy glands (PTG) multislice computed tomography (MSCT). The cause PHPT parathyroide...

Abstract A total of 4512 rhizobacteria were isolated at three stages of plant growth from Achillea ageratum colonizing a polluted site with an antimony concentration gradient. For 222 of these isolates auxin production (aux(+)) was verified in vitro. The percentage of aux(+) isolates increased with soil antimony concentration, as well as with plant growth stage. An amplified rDNA restriction an...
