  • Ultra-High-Field MR Neuroimaging [REVIEW ARTICLES]

    Balchandani, P., Naidich, T. P.
    15 Jul 2015 | 8:00 am
    SUMMARY: At ultra-high magnetic fields, such as 7T, MR imaging can noninvasively visualize the brain in unprecedented detail and through enhanced contrast mechanisms. The increased SNR and enhanced contrast available at 7T enable higher resolution anatomic and vascular imaging. Greater spectral separation improves detection and characterization of metabolites in spectroscopic imaging. Enhanced blood oxygen level–dependent contrast affords higher resolution functional MR imaging. Ultra-high-field MR imaging also facilitates imaging of nonproton nuclei such as sodium and phosphorus. These…
  • Mechanisms of Healing in Coiled Intracranial Aneurysms: A Review of the Literature [REVIEW ARTICLES]

    Brinjikji, W., Kallmes, D. F., Kadirvel, R.
    15 Jul 2015 | 8:00 am
    SUMMARY: Recanalization of intracranial aneurysms following endovascular coiling remains a frustratingly common occurrence. An understanding of the molecular and histopathologic mechanisms of aneurysm healing following coil embolization is essential to improving aneurysm occlusion rates. Histopathologic studies in coiled human and experimental aneurysms suggest that during the first month postcoiling, thrombus formation and active inflammation occur within the aneurysm dome. Several months following embolization, the aneurysm is excluded from the parent vessel by formation of a neointimal…

  • Unusual presentation of primary hyperparathyroidism: report of three cases

    Ruibin Huang
    16 Jul 2015 | 5:00 am
    Background: Primary hyperparathyroidism is an endocrinopathic condition characterized by hypersecretion of parathyroid hormone. Excess parathyroid hormone results in an altered state of osseous metabolism involving bone resorption and tissue change known as osteitis fibrosa cystica, which is the end stage of primary hyperparathyroidism. Osteitis fibrosa cystica is associated with the development of brown tumors, which are rare because hyperparathyroidism is now usually diagnosed and treated before symptoms develop. Brown tumors are rarely the first symptom of hyperparathyroidism and can…
  • Osteoporosis imaging: effects of bone preservation on MDCT-based trabecular bone microstructure parameters and finite element models

    Thomas Baum
    25 Jun 2015 | 5:00 pm
    Background: Osteoporosis is defined as a skeletal disorder characterized by compromised bone strength due to a reduction of bone mass and deterioration of bone microstructure predisposing an individual to an increased risk of fracture. Trabecular bone microstructure analysis and finite element models (FEM) have shown to improve the prediction of bone strength beyond bone mineral density (BMD) measurements. These computational methods have been developed and validated in specimens preserved in formalin solution or by freezing. However, little is known about the effects of preservation on…

  • A case report of ventricular dysfunction post pericardiocentesis: stress cardiomyopathy or pericardial decompression syndrome?

    Chadi Ayoub
    15 Jul 2015 | 5:00 pm
    We report a case of transient biventricular dysfunction post therapeutic pericardiocentesis, with classic features of stress cardiomyopathy (SCM). In our patient, the clinical and echocardiographic features were more in keeping with Takotsubo-type SCM than pericardial decompression syndrome (PDS). Our case is instructive in challenging our understanding of the aetiology of LV dysfunction complicating pericardiocentesis, and in highlighting the importance of careful clinical evaluation (altered heart rate and dyspnoea) in suspecting acute LV dysfunction after initial clinical improvement with…

  • The dynamic nature of assimilation and accommodation procedures in the brains of Chinese–English and English–Chinese bilinguals

    Yafeng Sun, Danling Peng, Guosheng Ding, Ting Qi, Amy S. Desroches, Li Liu
    19 Jul 2015 | 10:08 pm
    Abstract The framework of assimilation and accommodation has been proposed to explain the brain mechanisms supporting second language reading acquisition (Perfetti et al. [2007]: Bilingual Lang Cogn 10:131). Assimilation refers to using the procedures of the native language network in the acquisition of a new writing system, whereas accommodation refers to using second language procedures for reading the newly acquired writing system. We investigated assimilation and accommodation patterns in the brains of bilingual individuals by recruiting a group of Chinese–English bilinguals and a group…
  • Neuroticism and conscientiousness respectively constrain and facilitate short-term plasticity within the working memory neural network

    Danai Dima, Karl J. Friston, Klaas E. Stephan, Sophia Frangou
    19 Jul 2015 | 10:08 pm
    Abstract Individual differences in cognitive efficiency, particularly in relation to working memory (WM), have been associated both with personality dimensions that reflect enduring regularities in brain configuration, and with short-term neural plasticity, that reflects task-related changes in brain connectivity. To elucidate the relationship of these two divergent mechanisms, we tested the hypothesis that personality dimensions, which reflect enduring aspects of brain configuration, inform about the neurobiological framework within which short-term, task-related plasticity, as measured by…
  • Comparison of continuously acquired resting state and extracted analogues from active tasks

    15 Jul 2015 | 9:56 pm
    Abstract Functional connectivity analysis of brain networks has become an important tool for investigation of human brain function. Although functional connectivity computations are usually based on resting-state data, the application to task-specific fMRI has received growing attention. Three major methods for extraction of resting-state data from task-related signal have been proposed (1) usage of unmanipulated task data for functional connectivity; (2) regression against task effects, subsequently using the residuals; and (3) concatenation of baseline blocks located in-between task blocks.

  • The subthalamic nucleus during decision-making with multiple alternatives

    Max C. Keuken, Leendert Van Maanen, Rafal Bogacz, Andreas Schäfer, Jane Neumann, Robert Turner, Birte U. Forstmann
    15 Jul 2015 | 6:16 am
    Abstract Several prominent neurocomputational models predict that an increase of choice alternatives is modulated by increased activity in the subthalamic nucleus (STN). In turn, increased STN activity allows prolonged accumulation of information. At the same time, areas in the medial frontal cortex such as the anterior cingulate cortex (ACC) and the pre-SMA are hypothesized to influence the information processing in the STN. This study set out to test concrete predictions of STN activity in multiple-alternative decision-making using a multimodal combination of 7 Tesla structural and…

  • Leukoencephalopathy following Stereotactic Radiosurgery for Brain Metastases

    Daniel M. Trifiletti, Cheng-Chia Lee, David Schlesinger, James M. Larner, Zhiyuan Xu, Jason P. Sheehan
    27 Jul 2015 | 5:00 pm
    Stereotactic radiosurgery (SRS) in the treatment of multiple brain metastases has increased dramatically over the past decade. Although neurotoxicity is a known complication following whole brain radiation (WBRT), no evidence exists predicting leukoencephalopathy following SRS. Our results indicate that intracranial tumor burden, WBRT, and integral SRS dose each predict for leukoencephalopathy as defined by white matter changes on MRI. This study defines parameters which could be used to abrogate this radiation-induced delayed toxicity.

    23 Jul 2015 | 5:00 pm
    Clinical results indicated that systemic administration of TNF is hampered by dose-limiting toxicities. However, a novel delivery platform, CYT-6091 PEGylated gold nanoparticles incorporating TNF, was well tolerated in recent Phase I trials. Here, we observed synergistic tumor growth inhibition when CYT-6091 is combined with radiation therapy. CYT-6091 also reduced tumor interstitial fluid pressure to levels found in normal tissue and affected a subpopulation of tumor vessels.

    22 Jul 2015 | 5:00 pm
    In this study, local control of liver metastases SBRT was tested by comparing accumulated dose to the GTV using IGRT against planned dose to the PTV. The results showed that accumulated GTV doses were higher than planned dose (suggesting adequate PTV margins), and were stronger predictors for time to local progression on both univariate and multivariate models, suggesting a more evident dose-response with accumulated versus planned dose.
  • Definitive Management of Oligometastatic Melanoma in a Murine Model Using Combined Ablative Radiotherapy and Viroimmunotherapy

    Miran Blanchard, Kevin G. Shim, Michael P. Grams, Karishma Rajani, Rosa M. Diaz, Keith M. Furutani, Jill Thompson, Kenneth R. Olivier, Sean S. Park, Svetomir N. Markovic, Hardev Pandha, Alan Melcher, Kevin Harrington, Shane Zaidi, Richard Vile
    22 Jul 2015 | 5:00 pm
    We show here that Stereotactic Ablative Radiotherapy (SABR) can be combined with systemically administered vesicular stomatitis virus (VSV) expressing a tumor associated antigen to enhance survival in a model of oligometastatic melanoma. Whilst SABR controlled local tumor through direct cell ablation, systemic VSV-TAA generated T cell responses, which cleared metastatic tumors. This preclinical approach represents an effective, complementary combination therapy model, which can be further combined with additional immune modulator therapies.

    ABSTRACT PurposeMaternal obesity represents a challenge in the sonographic (US) assessment of fetal weight, and is a recognized risk factor for adverse pregnancy outcome. The objective of this secondary analysis of data from the Prospective Observational Trial to Optimize Pediatric Health in fetal growth restriction (FGR) Study (PORTO) was to describe the effect of maternal obesity on the accuracy of US in determining the estimated fetal weight (EFW) and the perinatal outcome of pregnancies affected by FGR. MethodsBetween 2010 and 2012, 1,116 women with nonanomalous singleton pregnancies with…

  • Increased SHP-1 expression results in radioresistance, inhibition of cellular senescence, and cell cycle redistribution in nasopharyngeal carcinoma cells

    Ziyi Sun
    28 Jul 2015 | 5:00 am
    Background: Radioresistance is the main limit to the efficacy of radiotherapy in nasopharyngeal carcinoma (NPC). SHP-1 is involved in cancer progression, but its role in radioresistance and senescence of NPC is not well understood. This study aimed to assess the role of SHP-1 in the radioresistance and senescence of NPC cells. Methods: SHP-1 was knocked-down and overexpressed in CNE-1 and CNE-2 cells using lentiviruses. Cells were irradiated to observe their radiosensitivity by colony forming assay. BrdU incorporation assay and flow cytometry were used to monitor cell cycle. A…

  • Whole-brain radiation therapy for brain metastases: detrimental or beneficial?

    Cengiz Gemici
    28 Jul 2015 | 5:00 am
    Stereotactic radiosurgery is frequently used, either alone or together with whole-brain radiation therapy to treat brain metastases from solid tumors. Certain experts and radiation oncology groups have proposed replacing whole-brain radiation therapy with stereotactic radiosurgery alone for the management of brain metastases. Although randomized trials have favored adding whole-brain radiation therapy to stereotactic radiosurgery for most end points, a recent meta-analysis demonstrated a survival disadvantage for patients treated with whole-brain radiation therapy and stereotactic…
  • Determining optimal planning target volume and image guidance policy for post-prostatectomy intensity modulated radiotherapy

    Linda Bell
    25 Jul 2015 | 5:00 pm
    Background: There is limited information available on the optimal Planning Target Volume (PTV) expansions and image guidance for post-prostatectomy intensity modulated radiotherapy (PP-IMRT). As the prostate bed does not move in a uniform manner, there is a rationale for anisotropic PTV margins with matching to soft tissue. The aim of this study is to find the combination of PTV expansion and image guidance policy for PP-IMRT that provides the best balance of target coverage whilst minimising dose to the organs at risk. Methods: The Cone Beam CT (CBCT) images (n = 377) of 40 patients who…
  • A phase I/II trial of intraoperative breast radiotherapy in an Asian population: 5-year results of local control and cosmetic outcome

    Mariko Kawamura
    24 Jul 2015 | 5:00 pm
    Background: To date, there are no reports of intraoperative radiotherapy (IORT) use with long-term follow up as a method of accelerated partial breast irradiation (APBI) in Asian countries. We initiated a prospective phase I/II clinical trial of IORT in Japan in 2007, and herein, we report the 5-year follow-up results.Materials and methodsThe following inclusion criteria were used for enrollment in the trial: (1) tumor size < 2.5 cm, (2) desire for breast-conserving surgery, (3) age >50 years, and (4) negative margins after resection. In February 2009, the eligibility criteria…

  • More On Gove's PR Stunt

    hstorm
    26 Jul 2015 | 3:03 am
    by Martin Odoni (Rhyming slang in the title completely unintentional. Honest.) On the subject of Michael Gove’s cunning stunt (!) at a Minor Injuries Unit in Shepton Mallet the other day, the Daily Telegraph has since printed a ‘clarification’ – really should be called a retraction – in the small print, and an image of it has gone viral over social media. (The fact that it took some days for it to do so perhaps tells us something about how quiet newspapers are about printing retractions; it therefore took a while for people to notice.) Anyway, here is the…

  • US to Remain World’s Leading Diagnostic X-Ray Systems Market to 2020

    Anjali Kalan
    28 Jul 2015 | 2:35 am
    MediPoint: Diagnostic X-ray Imaging Report The US is the world’s largest market for diagnostic X-ray systems, accounting for over 29% of global revenues in 2013. Despite the emergence of China, it will continue to hold the leading share of 25%+ by 2020. As reimbursement for X-ray examinations currently incurs lower physician fees than computerised tomography and magnetic resonance imaging scans in the US, there is less financial incentive for physicians to perform X-ray exams. On the other hand, the implementation of various healthcare reforms means that cuts in reimbursement for advanced…
  • Find and Repair a 230kV 800Amp Oil-Filled Power Cable Feels Like Mission Impossible

    Anool Mahidharia
    27 Jul 2015 | 1:01 pm
    How do you fix a shorted cable ? Not just any cable. An underground, 3-phase, 230kV, 800 amp per phase, 10 mile long one, carrying power from a power station to a distribution centre. It costs $13,000 per hour in downtime, counting 1989 money, and takes 8 months to fix. That’s almost $75 million. The Los Angeles Department of Water and Power did this fix about 26 years ago on the cable going from the Scattergood Steam Plant in El Segundo to a distribution center near Bundy and S.M. Blvd. [Jamie Zawinski] posted details on his blog in 2002. [Jamie] a.k.a [jwz] may be familiar to…

    Really irregular posts as of late, I apologise- many trips away etc. But here you go! The basis of Magnetic Resonance Imaging was actually initially discovered by Tesla (well, the Rotating Magnetic Field was discovered) in 1882- a fundamental discovery in physics, but also to be vital in chemistry and biology. NMR was discovered in1937 by Professor Rabi in Columbia Universityand Damadian saw that cancerous tissue contain more water so gave a different hydrogen signal. In 1973, Lauterbur produced the first NMR image and on July 3, 1977, the first human scan using MRI was made. MRIs are…

    I was going to wait to write about our appointment until after we returned back to Kentucky, but I just tried to summarize our appointment, which ended about an hour ago, to my mother-in-law and had already found myself hazy on some details so I figured I better document now so I can refer back to this post  to refresh my memory if the subject comes up again. Well, after a night of anxiety and dread, we got up hours before the sun and began our long-haul to West Palm Beach, Florida for Drew’s 6th follow-up with Dr. Paley.  I procrastinated packing just about as long as possible and…
