Introduction: Gastrointestinal angiodysplasia is a very common cause of digestive haemorrhage among patients with chronic renal insufficiency. It is well known that bleeding from angiodysplasias can be a difficult therapeutic problem since therapeutic possibilities are scarce and surgery is scolded with high mortality rate. Endoscopic argon plasma ablation therapy is a new, effective and safe treatment in the management of gastrointestinal angiodysplasia.
Case Report: We reported a case of a female haemodialysis patient aged 40 years. She was haemodialysed since 6 years in our center from unknown nephropathy. In March 2006, she complained of black stools and melena, and developed severe anaemia (Haemoglobin at 4 g/dL). Exploratory endoscope examination of the digestive tract showed the presence of bleeding from angiodysplastic lesions of the right colon. The patient had severe clinical picture extension of angiodysplastic lesions and frequent bleeding episodes. Bleeding arrest was observed after argon plasma coagulation, with a significant decrease of blood transfusions and improvement of anaemia.
Conclusion: Gastrointestinal angiodysplasia was reported to be an important complication in dialysis patients and was recognized as an important cause of erythropoietin-resistant anaemia. It can worsen vital prognosis. Argon plasma coagulation is an effective treatment in these patients.

This paper presents progress made toward the overarching goal to adapt single-photon-counting microcalorimeters to magnetic fusion energy research and demonstrate the value of such measurements for fusion. Microcalorimeter spectrometers combine the best characteristics of x-ray instrumentation currently available on fusion devices: high spectral resolution similar to an x-ray crystal spectrometer and broad spectral coverage sufficient to measure impurity species from Be to W. As a proof-of-principle experiment, a NASA-built x-ray microcalorimeter spectrometer has been installed on the Madison Symmetric Torus (MST) at the Wisconsin Plasma Physics Laboratory.

Nanogold is an emerging material for enhancing surface-enhanced Raman scattering (SERS), which enables the detection of hazardous analytes at trace levels. This study presents a simple, single-step plasma synthesis method to control the size and yield of Au nanoparticles by using plasma-liquid redox chemistry. The pin-based argon plasma reduces the Au precursor in under 5 min, synthesizing Au spherical particles ranging from ∼20 nm at 0.

Background: Seroma has been associated with some energy devices used in raising flaps during modified radical mastectomy. Perhaps, its occurrence might be reduced by determining the most effective technique for raising the flap. Hence, the wide array of energy devices available for mastectomy warrants a network meta-analysis for comparison to determine the most suitable for rseducing complications.

Mercury (Hg) determination in marine sediment is an analytical challenge due to the toxicity of this element even at low concentrations (up to 130 μg kg in marine sediments) and complex matrices. Therefore, it is necessary to use analytical techniques that have high sensitivity, selectivity, and low limits of quantification (LoQ). In this study, two methods that require sample treatment and one method with direct sampling were studied.

Plasma nitriding is one of the surface modifications that show more effectiveness than other methods. In this study, the plasma-based ion implantation (PBII) technique was performed on the surface of titanium alloy (Ti-6Al-4V, Ti64) using a mixture of nitrogen (N) and argon (Ar), resulting in a plasma-nitrided surface (TiN-Ti64). The surface composition of the TiN-Ti64 was verified through X-ray photoelectron spectroscopy (XPS).
