GASES DEL ABDOMEN SU UTILIDAD DIAGNOSTICA: GASES ENDOLUMINALES (SEGUNDA PARTE)

Revista Chilena de Radiología, 2002
La radiografía simple del abdomen sigue siendo un paso inicial y a veces el único examen de imágenes necesario para diagnosticar cuerpos extraños; ingeridos o introducidos por orificios naturales o artificiales, voluntaria o involuntariamente.

Ultra‐Radiostable Covalent Conformationally Interlocked Networks Enabling a Universal Radiometal‐Labeling Platform for Cancer Radioembolization

Advanced Science, EarlyView.
Conjugated poly(imide dioxime)‐based microspheres establish a radiometal coordination‐driven conformational interlocked network with ultra‐high radiostability. This platform enables low‐temperature, multi‐radionuclide labeling for SPECT/PET/MRI imaging and radionuclide therapy. Mechanistic insights from EXAFS and DFT reveal enhanced stability, while in

Syndrome coronaire aigu: un mode de révélation peu fréquent du phéochromocytome

The Pan African Medical Journal, 2015
Le phéochromocytome est une tumeur rare. Il se manifeste habituellement par la triade de Ménard ou par une hypertension artérielle. Des cas rares de phéochromocytome ont été révélés par un syndrome coronaire aigu.

Validation of dual energy X-ray absorptiometry measures of abdominal fat by comparison with magnetic resonance imaging in an Indian population.

PLoS ONE, 2012
ObjectiveAbdominal adiposity is an important risk factor for diabetes and cardiovascular disease in Indians. Dual energy X-ray absorptiometry (DXA) can be used to determine abdominal fat depots, being more accessible and less costly than gold standard ...

The effect of a combined tube current modulation system on dose delivered to patients undergoingthoracic and abdominal CT with a 128-slice scanner

Radiation Protection Dosimetry, 2012
Combined tube current modulation techniques (such as Care Dose4D used in this study) during computed tomography (CT) procedures bring together the benefits of the angular and z-axis modulation techniques, measuring X-ray attenuation profile in the z-axis together with the data from the perpendicular x-y direction with a sophisticated algorithm.

Transposable Element–Driven PIEZO Mutation Enhances Locust Flight in Plateau Hypoxia

Advanced Science, EarlyView.
Why transposable elements (TEs) persisted or expanded in genomes remains a mystery. Using integrated analysis of TE macro‐ and microevolution in locusts, our results showed that thousands of TE insertions promoted widespread adaptive variation. Subfamilies of candidate adaptive TEs amplified and reshaped species‐level genomic architecture.

Modulating Calcium Homeostasis via a Biomimetic Scaffold to Rescue Diabetic Ischemic Wounds

Advanced Science, EarlyView.
This strategy addresses impaired microcirculation and loss of extracellular matrix (ECM) guidance in diabetic wound healing. Musc@CP, a nanofibrous dressing combining an ECM‐mimetic chitosan‐pullulan scaffold with muscone, enhances perfusion by attenuating intracellular Ca2+ overload‐associated endothelial dysfunction.

Association of abdominal obesity with lumbar disc degeneration--a magnetic resonance imaging study.

PLoS ONE, 2013
PurposeTo evaluate whether midsagittal (abdominal) obesity in magnetic resonance imaging (MRI), waist circumference (WC) and body fat percentage are associated with lumbar disc degeneration in early adulthood.MethodsWe obtained the lumbar MRI (1.5-T ...
