Origin and stability of exomoon atmospheres: implications for habitability.

We study the origin and escape of catastrophically outgassed volatiles (H2O, CO2) from exomoons with Earth-like densities and masses of 0.1, 0.5 and 1 M⊕ orbiting an extra-solar gas giant inside the habitable zone of a young active solar-like star.

Renal cell carcinoma in patients with a solitary kidney after nephrectomy treated with radiofrequency ablation: mid term results.

This retrospective study aimed to evaluate the feasibility and effectiveness of radiofrequency ablation (RFA) in patients with solitary kidney for the treatment of renal cell carcinoma (RCC). Within 2 years 10 patients (seven males, three females; age 65+/-8 years) were treated. All patients had a history of nephrectomy of the contralateral kidney.

Radiofrequency ablation in the treatment of osteoid osteoma-5-year experience.

Purpose: This study aimed to determine the success and complication rates of radiofrequency ablation (RFA) in treatment of osteoid osteoma (OO) and duration of pain relief. Furthermore value of bone biopsy prior to the RFA was evaluated.

Materials And Methods: Within 61 months 39 patients (23 male, 16 female, 7-53 years, mean 18.

Radiofrequency ablation in combination with osteoplasty in the treatment of painful metastatic bone disease.

Purpose: To evaluate the feasibility and effectiveness of combining radiofrequency (RF) ablation and osteoplasty for pain reduction in the treatment of painful osteolytic metastases.

Materials And Methods: Within 5 years, 22 patients (15 men and seven women; median age, 64 years) with 28 lesions located in the thoracic and lumbar spine, sacrum, pelvis, acetabulum, femur, and tibia were treated. Underlying tumors were breast, lung, renal cell, thyroid, cancer of unknown primary, and multiple myeloma.

Effects of peripheral vascular intervention on ischemia-modified albumin.

Ischemia -modified albumin was regarded as an early marker of cardiac ischemia. On the other hand, it has been reported that increased ischemia-modified albumin levels are associated with unstable plaque processes like percutaneous coronary intervention, acute coronary syndrome or myocardial infarction. This prospective study aimed to investigate the role of ischemia-modified albumin in patients with peripheral vascular disease undergoing peripheral vascular intervention, a plaque-altering procedure without evidence of tissue ischemia.

Advances in digital radiography: physical principles and system overview.

During the past two decades, digital radiography has supplanted screen-film radiography in many radiology departments. Today, manufacturers provide a variety of digital imaging solutions based on various detector and readout technologies. Digital detectors allow implementation of a fully digital picture archiving and communication system, in which images are stored digitally and are available anytime.

Recurrent severe gastrointestinal bleeding and malabsorption due to extensive habitual megacolon.

Dilatation of the colon and the rectum, which is not attributable to aganglionosis, is a rare finding and can be the result of intractable chronic constipation. We report a rare case of a 29-year-old male patient with impressive megacolon, in whom Hirschsprung's or Chagas disease was ruled out. In the present case, dilatation of the colon was most likely due to a behavioral disorder with habitual failure of defecation.

High-spatial-resolution MR angiography of renal arteries with integrated parallel acquisitions: comparison with digital subtraction angiography and US.

Purpose: To retrospectively compare three-dimensional gadolinium-enhanced magnetic resonance (MR) angiography, performed with an integrated parallel acquisition technique for high isotropic spatial resolution, with selective digital subtraction angiography (DSA) and intravascular ultrasonography (US) for accuracy of diameter and area measurements in renal artery stenosis.

Materials And Methods: The study was approved by the institutional review board, and consent was obtained from all patients. Forty-five patients (17 women, 28 men; mean age, 62.

Critical limb ischemia: hybrid MR angiography compared with DSA.

Purpose: To compare a hybrid magnetic resonance (MR) angiography protocol with selective digital subtraction angiography (DSA) in patients with critical limb ischemia.

Materials And Methods: The study was approved by the institutional review board, and written consent was obtained from all patients. Pretreatment DSA and hybrid MR angiography were performed in 19 consecutive patients (15 men, four women; mean age, 69.

Morphological and functional assessment of the septal course of a left coronary artery originating from the right sinus of valsalva in a heart transplant patient.

A septal course of the left main coronary artery originating from the right sinus of Valsalva is a rare coronary anomaly of unknown clinical significance. We report on the morphological and functional assessment of this coronary anomaly detected incidentally in a 53-year-old asymptomatic man after orthotopic heart transplantation.
