Carotenoid profiles of different tissues (peel, pulp and whole fruit) of Spanish Sanguinos (red) and Verdal (orange) prickly pears (Opuntia ficus-indica spp.) have been characterized in detail and quantified for the first time. Carotenoids were determined by HPLC-PDA-MS (APCI(+)), using a reverse phase C30 column. A total of 9 xantophylls and 4 hydrocarbon carotenes were identified. Also, minor amounts of chlorophyll a, a' and b can be observed in Opuntia peel extracts. All carotenoids were found to be present in their free form (no carotenoid esters were detected)...

PURPOSE: We compared diagnostic performance of Magnetic Resonance (MR), Computed Tomography (CT) and Ultrasound (US) with (CEUS) and without contrast medium to identify peribiliary metastasis. METHODS: We identified 35 subjects with histological proven peribiliary metastases who underwent CEUS, CT and MR study. Four radiologists evaluated the presence of peribiliary lesions, using a 4-point confidence scale. Echogenicity, density and T1-Weigthed (T1-W), T2-W and Diffusion Weighted Imaging (DWI) signal intensity as well as the enhancement pattern during contrast studies on CEUS, CT and MR so as hepatobiliary-phase on MRI was assessed...

BACKGROUND: The imaging assessment of paraspinal muscle morphology and fatty infiltration has gained considerable attention in the past decades, with reports suggesting an association between muscle degenerative changes and low back pain (LBP). To date, qualitative and quantitative approaches have been used to assess paraspinal muscle composition. Though highly reliable, manual thresholding techniques are time consuming and not always feasible in a clinical setting. The tedious and rater-dependent nature of such manual thresholding techniques provides the impetus for the development of automated or semi-automated segmentation methods...

INTRODUCTION: The main health problems encountered in pediatric population in Senegal are low birth weigth malnutrition and infection. However, there is a lack of data on pediatric ENT diseases from west african population. This is no published data on any research work on pattern ENT pediatric done in Senegal. This study aimed at determining the pattern of common pediatric ENT diseases. PATIENTS AND METHODS: This was a retrospective descriptive study involving review of medical record of patients aged 0-16 years who presented ENT diseases from April 2011 to May 2013 (2 years)...

OBJECTIVE: To evaluate the clinical utility of the CAMUNI-MATISS 20-year risk score, recently validated for the Italian population, as additional screening tool for individuals at "low" (ESC-SCORE Project predicted 10-year risk ≤ 1%; no preventive action), "intermediate" (ESC-SCORE 1-4%; lifestyle modification/statin treatment) and "high" risk (ESC-SCORE≥ 4% or diabetes; statin treatment) according to the Italian regulation. DESIGN AND METHOD: 40-65 years old initially CVD-free participants to 7 population-based cohorts enrolled in Northern and Central Italy between 1986 and 1996 were followed-up (median 16 years, IQR: 12-20) to the first occurrence of coronary event or ischemic stroke (fatal or non-fatal), coronary or carotid revascularizations...

OBJECTIVE: The correspondence between the anatomical STN and the STN observed in T2-weighted MRI images used for deep brain stimulation (DBS) targeting remains unclear. Using a new method, we compared the STN borders seen on MRI images with those estimated by intraoperative microelectrode recordings (MER). APPROACH: We developed a method to automatically generate a detailed estimation of STN shape and the location of its borders, based on multiple-channel MER measurements...

PURPOSE: To detect if a difference of T2 ratio, defined as the signal intensity (SI) of the myocardium divided by the SI of the skeletal muscle on T2-weigthed cardiac magnetic resonance (CMR) imaging, exists between patients with systemic amyloidosis, by comparison to control subjects. To determine if a relationship exists between T2 ratio and the overall mortality. MATERIALS AND METHODS: CMR imaging examinations of 73 consecutive patients (48 men, 25 women; mean age, 63 years±15[SD]) with amyloidosis and suspicion of CA and 27 control subjects were retrospectively analyzed after institutional review board approval...

AIM: Holmium laser enucleation of prostate (HoLEP) is renowned for the difficulty of its learning curve. Our aim was to evaluate the interest of a three-step tutorial in the HoLEP learning curve, in a university center. METHODS: It is a retrospective, monocentric study of the 82 first procedures done consecutively by the same operator with a proctoring in early experience and after 40 procedures. For all patients were noted: enucleation efficiency (g/min), morcellation efficiency (g/min), percentage of enucleated tissue (enucleated tissue/adenome weigth evaluated by ultrasonography...

BACKGROUND: We theorized that active cervical extension should influence the position of the nucleus pulposus (NP) within the intervertebral disk (IVD) in the sagittal plane. Although several studies on the lumbar IVD have been conducted, there are no quantitative data for in vivo positional changes of the NP in the cervical IVD. OBJECTIVE: To evaluate the influence and mechanism of cervical extension on the deformation and migration of IVD and NP in the sagittal plane and understand underlying mechanisms of the extension maneuver...

Victoza (liraglutide) is a modern antidiabetic drug of GLP1 (glucagone like peptide) analogue group; since 2009 registered in Czech republic. VICTOZA is used in therapy of type 2 diabetic patients with preserved endougenous insulin secretion, usually in combination with other peroral antidiabetic drugs or with basal insulin. VICTOZA is applied once a day subcutaneously. The characteristical antidiabetic effect with β cell protection is enhanced with supportive weigth reduction effect. Positive cardiovascular influence is expected, however data from recent studies are not available at this time...

INTRODUCTION: Early promising data suggest that combined use of both morphological and functional MRI (multi-parametric MR, mpMRI) including MRSI, DWI and DCE may be of additional value for prostate cancer localization and its local staging. The objective of this paper is to evaluate the diagnostic performance of mpMRI in the detection of prostate cancer. METHODS: Thirty-one consecutive male patients were screened to be enrolled in a single center prospective observational study...

To evaluate MRI for neoadjuvant therapy response assessment in locally advanced rectal cancer (LARC) using dynamic contrast enhanced-MRI (DCE-MRI) and diffusion weighted imaging (DWI), we have compared magnetic resonance volumetry based on DCE-MRI (V(DCE)) and on DWI (V(DWI)) scans with conventional T2-weighted volumetry (V(C)) in LARC patients after neoadjuvant therapy. Twenty-nine patients with LARC underwent MR examination before and after neoadjuvant therapy. A manual segmentation was performed on DCE-MR postcontrast images, on DWI (b-value 800 s/mm(2)), and on conventional T2-weighted images by two radiologists...

REVIEW
A Valle, J Alvarado-Mesén, M E Lanio, C Álvarez, J A R G Barbosa, I F Pazos
Actinoporins are basic pore-forming proteins produced by sea anemones, with molecular weight around 20 kDa showing high affinity for sphingomyelin-containing membranes. Most sea anemones produce more than one actinoporin isoform differing in isoelectric point, molecular weigth and cytolytic activity. Examples of sea anemones with actinoporin isoforms are: Actinia equina with at least five isoform genes; Actinia tenebrosa, three isoforms; Actinia fragacea, five isoforms; Actineria villosa, Phyllodiscus semoni, Stichodactyla helianthus and Oulactis orientalis, with two isoforms each one, and Heteractis crispa with twenty-four isoforms...

OBJECTIVE: To explore the relationship and possible mechanisms between testicular oxidative injury caused by DBP and the testosterone synthesis pathway. METHODS: Twenty-four male Wistar male rats (4-wk-old) were randomly divided into 4 groups, three doses of DBP (80, 200 and 500 mg/kg) groups and a vehicle (corn oil) control group, 6 animals each. The rats were respectively administered by gavage once a day for four weeks. They were sacrificed after 4 weeks treatment and the body weights, testis, epididymis were weighed, respectively...
