1Contrast-enhanced ultrasound in diagnosis and characterization of focal hepatic lesions显示文摘The extensive use of imaging techniques in differential diagnosis of abdominal conditions and screening of hepatocellular carcinoma in patients with chronic hepatic diseases,has led to an important increase in identification of focal liver lesions.The development of contrastenhanced ultrasound(CEUS) opens a new window in the diagnosis and follow-up of these lesions.This technique offers obvious advantages over the computed tomography and magnetic resonance,without a decrease in its sensitivity and specificity.The new second generation contrast agents,due to their intravascular distribution,allow a continuous evaluation of the enhancement pattern,which is crucial in characterization of liver lesions.The dual blood supply in the liver shows three different phases,namely arterial,portal and late phases.The enhancement during portal and late phases can give important information about the lesion's behavior.Each liver lesion has a different enhancement pattern that makes possible an accurate approach to their diagnosis.The role of emerging techniques as a contrastenhanced three-dimensional US is also discussed.In this article,the advantages,indications and technique employed during CEUS and the different enhancement patterns of most benign and malignant focal liver lesions are discussed.Inés Gómez Molins Juan Manuel Fernández Font Juan Carrero álvaro Jose Luís Lledó Navarro Marta Fernández Gil Conrado M Fernández Rodríguez 2010World Journal of Radiology2010,2,12:14
2Antibacterial approaches in tissue engineering using metal ions and nanoparticles:From mechanisms to applications显示文摘Bacterial infection of implanted scaffolds may have fatal consequences and,in combination with the emergence of multidrug bacterial resistance,the development of advanced antibacterial biomaterials and constructs is of great interest.Since decades ago,metals and their ions had been used to minimize bacterial infection risk and,more recently,metal-based nanomaterials,with improved antimicrobial properties,have been advocated as a novel and tunable alternative.A comprehensive review is provided on how metal ions and ion nanoparticles have the potential to decrease or eliminate unwanted bacteria.Antibacterial mechanisms such as oxidative stress induction,ion release and disruption of biomolecules are currently well accepted.However,the exact antimicrobial mechanisms of the discussed metal compounds remain poorly understood.The combination of different metal ions and surface decorations of nanoparticles will lead to synergistic effects and improved microbial killing,and allow to mitigate potential side effects to the host.Starting with a general overview of antibacterial mechanisms,we subsequently focus on specific metal ions such as silver,zinc,copper,iron and gold,and outline their distinct modes of action.Finally,we discuss the use of these metal ions and nanoparticles in tissue engineering to prevent implant failure.Maria Godoy-Gallardo Ulrich Eckhard Luis M.Delgado Yolanda J.D.de Roo Puente Mireia Hoyos-Nogués F.Javier Gil Roman A.Perez 2021Bioactive Materials2021,6,12:14
3Schistosoma mansoni proteins attenuate gastrointestinal motility disturbances during experimental colitis in mice显示文摘AIM:To investigate the therapeutic effect of Schistosoma mansoni(S.mansoni) soluble worm proteins on gastrointestinal motility disturbances during experimental colitis in mice. METHODS:Colitis was induced by intrarectal injection of trinitrobenzene sulphate(TNBS) and 6 h later,mice were treated ip with S.mansoni proteins.Experiments were performed 5 d after TNBS injection.Inflammationwas quantified using validated inflammation parameters. Gastric emptying and geometric center were measured to assess in vivo gastrointestinal motility.Peristaltic activity of distal colonic segments was studied in vitro using a modified Trendelenburg set-up.Cytokine profiles of T-lymphocytes isolated from the colon were determined by real time reverse transcriptase-polymerase chain reaction. RESULTS:Intracolonic injection of TNBS caused severe colitis.Treatment with S.mansoni proteins significantly ameliorated colonic inflammation after 5 d.TNBS did not affect gastric emptying but significantly decreased the geometric center and impaired colonic peristaltic activity 5 d after the induction of colitis.Treatment with S.mansoni proteins ameliorated these in vivo and in vitro motility disturbances.In addition,TNBS injection caused a downregulation of effector T cell cytokines after 5 d,whereas a S.mansoni protein effect was no longer observed at this time point. CONCLUSION:Treatment with S.mansoni proteins attenuated intestinal inflammation and ameliorated motility disturbances during murine experimental colitis.Nathalie E Ruyssers Benedicte Y De Winter Joris G De Man Natacha D Ruyssers Ann J Van Gils Alex Loukas Mark S Pearson Joel V Weinstock Paul A Pelckmans Tom G Moreels 2010World Journal of Gastroenterology2010,16,6:11
4Male osteoporosis: A review显示文摘Osteoporosis in men is a heterogeneous disease that has received little attention.However,one third of worldwide hip fractures occur in the male population.This problem is more prevalent in people over70 years of age.The etiology can be idiopathic or secondary to hypogonadism,vitamin D deficiency and inadequate calcium intake,hormonal treatments for prostate cancer,use of toxic and every disease or drug use that alters bone metabolism.Risk factors such as a previous history of fragility fracture should be assessed for the diagnosis.However,risk factors in men are very heterogeneous.There are significant differences in the pharmacological treatment of osteoporosis between men and women fundamentally due to the level of evidence in published trials supporting each treatment.New treatments will offer new therapeutic prospects.The goal of this work is a revision of the present status knowledge about male osteoporosis.Antonio Herrera Antonio Lobo-Escolar Jesús Mateo Jorge Gil Elena Ibarz Luis Gracia 2012World Journal of Orthopedics2012,3,12:5

6Functional optoacoustic neuro-tomography for scalable whole-brain monitoring of calcium indicators显示文摘Non-invasive observation of spatiotemporal activity of large neural populations distributed over entire brains is a longstanding goal of neuroscience.We developed a volumetric multispectral optoacoustic tomography platform for imaging neural activation deep in scattering brains.It can record 100 volumetric frames per second across scalable fields of view ranging between 50 and 1000 mm^(3) with respective spatial resolution of 35–200μm.Experiments performed in immobilized and freely swimming larvae and in adult zebrafish brains expressing the genetically encoded calcium indicator GCaMP5G demonstrate,for the first time,the fundamental ability to directly track neural dynamics using optoacoustics while overcoming the longstanding penetration barrier of optical imaging in scattering brains.The newly developed platform thus offers unprecedented capabilities for functional whole-brain observations of fast calcium dynamics;in combination with optoacoustics'well-established capacity for resolving vascular hemodynamics,it could open new vistas in the study of neural activity and neurovascular coupling in health and disease.X Luís Deán-Ben Gali Sela Antonella Lauri Moritz Kneipp Vasilis Ntziachristos Gil G Westmeyer Shy Shoham Daniel Razansky 2016Light(Science & Applications)2016,5,1:5
7Review of allergic contact dermatitis: Scratching the surface显示文摘Contact dermatitis-including allergic contact dermatitis(ACD)-n and results in over four million lost work days per year in the United States alone. ACD is a classic example of a type IV delayed hypersensitivity reaction, and represents a significant burden on the health system, economy, and patient quality of life. Thorough history taking, clinical examination, histologic evaluation, and patch testing are keys to diagnosing contact dermatitis. Patch testing, especially with comprehensive and customized panels based on the patient's exposure history, is particularly useful in identifying potential allergens inthe case of allergic contact dermatitis. ACD management requires a combination of direct medical intervention, patient education, and appropriate environmental modification to prevent exposure to offending allergens in the home or workplace. Continuing advances in the study of ACD has led to an increased understanding of the disease processes, new methods for diagnosis, and improved management. This article reviews ACD-aiming to connect recent investigational data with the current clinical understanding of disease pathophysiology, diagnostic techniques, and management strategies.Gil S Weintraub Isabella Nga Lai Christina N Kim 2015World Journal of Dermatology2015,4,2:3
