Anti-Angiogenic Treatment (Sunitinib) for Disseminated Malignant Haemangiopericytoma: A Case Study and Review of the Literature
Introduction: A meningeal haemangiopericytoma (HP) is a mesenchymal tumour that makes up less than 1% of all CNS tumours. HPs arise from pericytes and present high rates of recurrence and distant metastasis. The primary treatment option is surgery. When the disease is disseminated, chemotherapy produces a weak and short-lived response; therefore, new drugs are needed. Case Presentation: We describe the case of a 65-year-old woman with a 13-year history of recurrent HP. After local treatment with radiotherapy, she developed metastases that required systemic treatment, and treatment with sunitinib, an oral inhibitor of the vascular endothelial growth factor receptor and the platelet-derived growth factor receptor, was initiated. As a result, radiological stabilisation of the systemic disease was maintained for over 12 months. Conclusions: Anti-angiogenic agents can be useful for treating disseminated HP, but further studies are needed to confirm their possible role in controlling metastatic disease

Distribution of Brown Adipose Tissue Radiodensity in Young Adults: Implications for Cold [18F]FDG-PET/CT Analyses
Procedures: We measured 125 individuals after a personalized cooling protocol with a static
[18F]FDG-PET/CT scan. We quantified BAT using different combination of threshold in every
single HU for all participants.
Results: We observed that the SUV threshold influences BAT quantification by [18F]FDG-PET/
CT scans more than the HU range. We found that the range from − 50 to − 10 HU had the
highest proportion of total BAT volume (43.2 %), which represents 41.4 % of the total BAT
metabolic activity in our cohort. We also observed that BAT volume was not different between
categories of body mass index, as well as BAT activity (SUVmean). In addition, BAT was less
dense in women than in men, although the BAT activity (SUVmean) was higher in all ranges of
HU. We also observed that the radiodensity of BAT located in the cervical area was mainly in the
range from − 50 to − 10 HU.
Conclusion: Therefore, all future human studies using static [18F]FDG-PET/CT scans should
include BAT in the radiodensity range from − 50 to − 10 HU.This study was supported by the Spanish Ministry of Economy and Competitiveness,

Control of quantum interference in the quantum eraser
We have implemented an optical quantum eraser with the aim of studying this
phenomenon in the context of state discrimination. An interfering single photon
is entangled with another one serving as a which-path marker. As a consequence,
the visibility of the interference as well as the which-path information are
constrained by the overlap (measured by the inner product) between the
which-path marker states, which in a more general situation are non-orthogonal.
In order to perform which-path or quantum eraser measurements while analyzing
non-orthogonal states, we resort to a probabilistic method for the unambiguous
modification of the inner product between the two states of the which-path
marker in a discrimination-like process.Comment: Submitted to New Journal of Physics, March 200
Impact of cow's milk intake on exercise performance and recovery of muscle function: a systematic review
Dairy products are thought to improve recovery after both resistance and endurance exercises due to their nutritional proprieties. We systematically reviewed the effects of dairy product intake on exercise performance and recovery of muscle function in humans. A literature search was conducted in the MEDLINE (via PubMed) and Web of Science databases from their inception to 15th April 2018. The initial search retrieved 7708 articles, and a total of 11 studies were finally included after applying inclusion and exclusion criteria. All the selected studies were conducted with cow's milk. Whereas some studies found significant positive effect of cow's milk on exercise performance and recovery of muscle function, others did not find any effect. These controversies could be due to the heterogeneity of cow's milk ingestion (e.g., amount of cow's milk, timing of consuming the cow's milk), to the type of intervention, and to the large heterogeneity of outcomes measured. Limited studies exist examining the effects of cow's milk consumption and its influence on exercise performance and recovery of muscle function, therefore further studies are needed to draw more definitive conclusions.The study was supported by the Spanish Ministry of Education (FPU 13/04365 and 15/04059), by the Redes temáticas de investigación cooperativa RETIC (Red SAMID RD16/0022), and by the University of Granada Plan Propio de Investigacion 2016 -Excellence actions: Unit of Excellence on Exercise and Health (UCEES) - and Plan Propio de Investigación 2018 - Programa Contratos-Puente, and the Junta de Andalucía, Consejería de Conocimiento, Investigación y Universidades (ERDF: ref.

Factores personales y ambientales asociados con el desplazamiento activo al colegio de los escolares españoles
The purpose of this study was to analyse the associations of personal and environmental factors with mode of commuting to school in children. A total of 745 schoolchildren (363 girls) aged 6-12 years from the province of Granada (Spain) participated in the study. Participants completed a questionnaire about mode of commuting to school, personal factors (i.e. barriers to walking to school, enjoyment on the way to school, who they go to school with) and environmental factors (i.e. time from house to school, distance to school, and safety on the way). A total of 57.2% children walked to school, 40.3% used the car, 1.2% motorcycled, .7% used the bus and .6% bicycled. Travelling alone to school [Odds ratio (OR), 10.049; 95% confidence interval (CI), 3.950 - 25.567], living close to the school (OR, 16.439; 95%CI, 5.717- 47.271) and perceiving a safe way to school (OR, 2.365; 95%CI, 1.665- 3.360) were associated with active commuting to school
Observational constraints to boxy/peanut bulge formation time
Boxy/peanut bulges are considered to be part of the same stellar structure as
bars and both could be linked through the buckling instability. The Milky Way
is our closest example. The goal of this letter is determining if the mass
assembly of the different components leaves an imprint in their stellar
populations allowing to estimate the time of bar formation and its evolution.
To this aim we use integral field spectroscopy to derive the stellar age
distributions, SADs, along the bar and disc of NGC 6032. The analysis shows
clearly different SADs for the different bar areas. There is an underlying old
(>=12 Gyr) stellar population for the whole galaxy. The bulge shows star
formation happening at all times. The inner bar structure shows stars of ages
older than 6 Gyrs with a deficit of younger populations. The outer bar region
presents a SAD similar to that of the disc. To interpret our results, we use a
generic numerical simulation of a barred galaxy. Thus, we constrain, for the
first time, the epoch of bar formation, the buckling instability period and the
posterior growth from disc material. We establish that the bar of NGC 6032 is
old, formed around 10 Gyr ago while the buckling phase possibly happened around
8 Gyr ago. All these results point towards bars being long-lasting even in the
presence of gas.Comment: Accepted for publication in MNRAS Letter
Effectiveness of a Tai-Chi Training and Detraining on Functional Capacity, Symptomatology and Psychological Outcomes in Women with Fibromyalgia
Background. The purpose was to analyze the effects of Tai-Chi training in women with fibromyalgia (FM).
Methods. Thirty-two women with FM (mean age, 51.4 ± 6.8 years) attended to Tai-Chi intervention 3 sessions weekly for 28 weeks. The outcome measures were: tenderness, body composition, functional capacity and psychological outcomes (Fibromyalgia impact questionnaire (FIQ), Short Form Health Survey 36 (SF-36)). Results. Patients showed improvements on pain threshold, total number of tender points and algometer score (all P < 0.001). The intervention was effective on 6-min walk (P = 0.006), back scratch (P = 0.002), handgrip strength (P = 0.006), chair stand, chair sit & reach, 8 feet up & go and blind flamingo tests (all P < 0.001). Tai-Chi group improved the FIQ total score (P < 0.001) and six subscales: stiffness (P = 0.005), pain, fatigue, morning tiredness, anxiety, and depression (all P < 0.001). The intervention was also effective in six SF-36 subscales: bodily pain (P = 0.003), vitality (P = 0.018), physical functioning, physical role, general health, and mental health (all P < 0.001). Conclusions. A 28-week Tai-Chi intervention showed improvements on pain, functional capacity, symptomatology and psychological outcomes in female FM patients
