Design of pyrazolo-pyrrolo-pyrazines and pyrazolo-pyrrolo-diazepines via AuCl3-catalyzed and NaH-supported cyclization of N -propargyl pyrazoles
(American Chemical Society, 2015)
A concise synthetic methodology for new heterocyclic scaffolds, such as pyrazolo-pyrrolo-pyrazine and pyrazolo-pyrrolo-diazepine skeletons, was developed. The key features of this method include (i) synthesis of pyrrole-derived ...
Frequency and voltage dependence of electric and dielectric properties of Au/TiO2/n-4H-SiC (metal-insulator-semiconductor) type Schottky barrier diodes
(Institute of Physics Publishing, 2015)
The main electrical and dielectric properties of Au/TiO2/n-4H-SiC (MIS) type Schottky barrier diodes (SBDs) have been investigated as functions of frequency and applied bias voltage. We believe that the use of high dielectric ...
Boric acid: A simple molecule of physiologic, therapeutic and prebiotic significance
(Walter de Gruyter GmbH, 2015)
Boric acid, H3BO3, is a weak acid and at physiological pH is in the form of an uncharged small molecule. Behaving as a Lewis acid, it forms complexes with amino- and hydroxy acids, carbohydrates, nucleotides and vitamins ...
CO2 gas detection properties of a TIO2/Al2O3 heterostructure under UV light irradiation
(Institute of Physics Publishing, 2015)
Al/TiO2/p-Si and Al/TIO2/Al2O3/p-Si samples were prepared using the atomic layer deposition method (ALD) and their gas sensing properties were investigated. The electrical properties of the samples were studied using a two ...
The effect of finely-divided fillers on the adhesion strengths of epoxy-based adhesives
(Elsevier Ltd, 2015)
It was aimed to investigate the effect of five different fillers on the adhesion strength of the metal parts used in different industries by using T-peel and lap-shear tests with respect to ASTM D 1876 and ASTM D 1002 ...
The homogeneity map method for speckle reduction in diagnostic ultrasound images
(Elsevier B.V., 2015)
This paper proposes a new method to reduce speckle noise in diagnostic ultrasound images by improving the speckle reduction capacity of an edge-sensitive filter. A homogeneity map is generated according to the local ...
Higher body mass index and larger waist circumference may be predictors of thyroid carcinoma in patients with Hürthle-cell lesion/neoplasm fine-needle aspiration diagnosis
(Blackwell Publishing Ltd, 2015)
Objective High body mass index (BMI) has been found to be associated with raised thyroid cancer risk, particularly in women. We examined the associations for BMI and waist circumference (WC) with thyroid cancer risk among ...
Impaired endothelial function in patients with mild primary hyperparathyroidism improves after parathyroidectomy
(Blackwell Publishing Ltd, 2015)
Background Primary hyperparathyroidism (PHPT) is associated with cardiovascular morbidity; however, data on the reversibility of cardiovascular disease in mild primary hyperparathyroidism are conflicting. The aim of this ...
Effect of androgen replacement therapy on atherosclerotic risk markers in young-to-middle-aged men with idiopathic hypogonadotropic hypogonadism
(Blackwell Publishing Ltd, 2015)
Objective: Idiopathic hypogonadotropic hypogonadism is a rare disorder. This study evaluated the effect of androgen replacement therapy on atherosclerotic risk markers in young-to-middle-aged men with this disorder. Design ...
Effects of potentilla fulgens as a prophylactic agent for ischemia/reperfusion injury in the rat ovary
(Science Printers and Publishers Inc., 2015)
OBJECTIVE: To investigate the effects of Potentilla fulgens as a prophylactic agent on ischemia/reperfusion (I/R) injury in the rat ovary. STUDY DESIGN: A total of 32 Wistar rats were divided into 4 equal groups: (I) sham, ...
