Two new Gd(III) complexes based on 5-aryl-2,2’-bipyridines with the DTTA residue at C6’ position were obtained. Primary photophysical properties of chelates have been studied. The resulting are interest by potential using, e.g., as contrast reagents for magnetic resonance imaging (MRI).

Harmonic problems are increasing on MV systems, especially with the application of power factor correction capacitors or extensive underground networks that resulting resonances close to the fifth harmonic. This paper describes two case studies of solving harmonic resonance problems on distribution systems with the design of harmonic filters that provide both power factor correction and harmoni...

recognizing the advantages of primary care as a means of improving the entire health system, this text comments on reforms of publicly funded primary health centers, and the rapid development of private forprofit providers in sweden. many goals and expectations are connected to such reforms, which equally require critical analyses of scarce resources, professional trust/motivation and business ...

primary colorectal lymphoma (pcl) is a rare condition that accounts for a small percentage of all gastrointestinal (gi) malignancies. there are several reports in the literature regarding the most common features of pcl. however, primary lymphoma in the rectosigmoid junction has been rarely reported. our case was a 67-year-old male who presented with non-specific symptoms of bowel obstruction w...

background: so far, non-invasive diagnostic approaches such as ultrasound, magnetic resonance imaging, or blood tests do not have sufficient diagnostic power for endometriosis disease. lack of a non-invasive diagnostic test contributes to the long delay between onset of symptoms and diagnosis of endometriosis. objective: the present study focuses on the identification of predictive biomarkers i...

calcifying aponeurotic fibroma (caf) is a rare, benign fibroblastic tumor that typically occurs in the palms of the hands and soles of the feet, in children and adolescents. due to its infiltrative nature, this tumor can mimic malignancy on preoperative magnetic resonance imaging (mri) and has a predilection for local recurrence. there are very few reports in the literature that describe featur...
