1超高强微钢纤维增韧混凝土的制备及其力学性能研究显示文摘高脆性是超高强混凝土难以被广泛应用的主要原因之一。为降低脆性,利用长度为6mm与13mm的三种微钢纤维,制备超高强微钢纤维混凝土,研究不同纤维长径比及掺量条件下混凝土的力学性能指标,其中包括ASTMC1018方法测试超高强微纤维混凝土的抗弯韧性。试验结果显示:随纤维掺量的增加,超高强混凝土能量吸收能力增加明显;与不掺纤维时相比,1.0%体积掺量下三种纤维混凝土的初始裂缝强度、抗折强度和韧性指数均有显著提高,掺量2.0%时初始裂缝强度、抗折强度和韧性指数的增加受到影响;长度为6mm的纤维在2.0%掺量时抗压强度相对较大,而长度为13mm的两种纤维在掺量1.0%时抗压强度较高;掺入3种纤维的混凝土劈拉强度和弹性模量也由于纤维的掺入而有所增加。结果表明,微钢纤维用于增韧超高强混凝土时,宜采用适宜掺量。王冲 Liza O'Moore 2009土木工程学报2009,42,6:17
2Pneumatosis cystoides intestinalis显示文摘Pneumatosis cystoides intestinalis(PCI) is a rare condition that may be associated with a variety of diseases.The presenting clinical picture may be very heterogeneous and represent a challenge for the clinician.In the present paper we describe both a common and an uncommon clinical presentation of PCI and review the pertaining literature.Our cases confirm that,apart from asymptomatic cases,the clinical presentation of PCI may be widely different and suggest that a new onset of stipsis might be the presenting symptom.Diagnosis might be suggested by a simple X-ray of the digestive tract showing a change in the characteristics of the intestinal wall in two-thirds of these patients.However,one third of the patients do not have a suggestive X-ray and require a computed tomography(CT) scan/nuclear magnetic resonance that may reveal a thickened bowel wall containing gas to confirm the diagnosis and distinguish PCI from intraluminal air or submucosal fat.CT also allows the detection of additional findings that may suggest an underlying,potentially worrisome cause of PCI such as bowel wall thickening,altered contrast mucosal enhancement,dilated bowel,soft tissue stranding,ascites and the presence of portal air.Our results also point out that clinicians and endoscopists should be aware of the possible presentations of PCI in order to correctly manage the patients affected with this disease and avoid unnecessary surgeries.The increasing number of colonoscopies performed for colon cancer screening makes PCI more frequently casually encountered and/or provoked,therefore the possible endoscopic appearances of this disease should be well known by endoscopists.Francesco Azzaroli Laura Turco Liza Ceroni Stefania Sartoni Galloni Federica Buonfiglioli Claudio Calvanese Giuseppe Mazzella 2011World Journal of Gastroenterology2011,17,44:16
3Shortness of breath in clinical practice: A case for left atrial function and exercise stress testing for a comprehensive diastolic heart failure workup显示文摘The symptom cluster of shortness of breath(SOB) contributes significantly to the outpatient workload of cardiology services. The workup of these patients includes blood chemistry and biomarkers, imaging and functional testing of the heart and lungs. A diagnosis of diastolic heart failure is inferred through the exclusion of systolic abnormalities, a normal pulmonary function test and normal hemoglobin, coupled with diastolic abnormalities on echocardiography. Differentiating confounders such as obesity or deconditioning in a patient with diastolic abnormalities is difficult. While the most recent guidelines provide more avenues for diagnosis, such as incorporating the left atrial size, little emphasis is given to understanding left atrial function, which contributes to at least 25% of diastolic left ventricular filling; additionally, exercise stress testing to elicit symptoms and test the dynamics of diastolic parameters, especially when access to the 'gold standard' invasive tests is lacking, presents clinical translational gaps. It is thus important in diastolic heart failure work up to understand left atrial mechanics and the role of exercise testing to build a comprehensive argument for the diagnosis of diastolic heart failure in a patient presenting with SOB.Pupalan Iyngkaran Nagesh S Anavekar Christopher Neil Liza Thomas David L Hare 2017World Journal of Methodology2017,7,4:5
4Traumatic brain injury:A case-based review显示文摘BACKGROUND:Traumatic brain injuries are common and costly to hospital systems.Most of the guidelines on management of traumatic brain injuries are taken from the Brain Trauma Foundation Guidelines.This is a review of the current literature discussing the evolving practice of traumatic brain injury.DATA SOURCES:A literature search using multiple databases was performed for articles published through September 2012 with concentration on meta-analyses,systematic reviews,and randomized controlled trials.RESULTS:The focus of care should be to minimize secondary brain injury by surgically decompressing certain hematomas,maintain systolic blood pressure above 90 mmHg,oxygen saturations above 93%,euthermia,intracranial pressures below 20 mmHg,and cerebral perfusion pressure between 60-80 mmHg.CONCLUSION:Much is still unknown about the management of traumatic brain injury.The current practice guidelines have not yet been sufficiently validated,however equipoise is a major issue when conducting randomized control trials among patients with traumatic brain injury.Liza Victoria S Escobedo Joseph Habboushe Haytham Kaafarani George Velmahos Kaushal Shah Jarone Lee 2013World Journal of Emergency Medicine2013,4,4:4

6Is autophagy an elective strategy to protect neurons from dysregulated cholesterol metabolism?显示文摘The balance of autophagy, apoptosis and necroptosis is crucial to determine the outcome of the cellular response to cholesterol dysregulation. Cholesterol plays a major role in regulating the properties of cell membranes, especially as regards their fluidity, and the regulation of its biosynthesis influences the shape and functions of these membranes. Whilst dietary cholesterol can easily be distributed to most organs, the central nervous system, whose membranes are particularly rich in cholesterol, mainly relies on de novo synthesis. For this reason, defects in the biosynthesis of cholesterol can variably affect the development of central nervous system. Moreover, defective synthesis of cholesterol and its intermediates may reflect both on structural cell anomalies and on the response to inflammatory stimuli. Examples of such disorders include mevalonate kinase deficiency, and Smith-Lemli-Opitz syndrome, due to deficiency in biosynthetic enzymes, and type C Niemann-Pick syndrome, due to altered cholesterol trafficking across cell compartments. Autophagy, as a crucial pathway dedicated to the degradation of cytosolic proteins and organelles, plays an essential role in the maintenance of homeostasis and in the turnover of the cytoplasmic material especially in the presence of imbalances such as those resulting from alteration of cholesterol metabolism. Manipulating the process of autophagy can offer possible strategies for improving neuronal cell viability and function in these genetic disorders.Elisa Piscianz Liza Vecchi Brumatti Alberto Tommasini Annalisa Marcuzzi 2019Neural Regeneration Research2019,14,4:2
7海绵负载纳米Al2O3复合吸附剂去除水中硒研究显示文摘研究制备了海绵负载纳米Al2O3微球的复合吸附剂(NAS),并用于对Se(Ⅳ)和Se(Ⅵ)的吸附。结果表明,合成的纳米Al2O3微球(NAO)的平均尺寸为200~400 nm,在海绵上负载NAO会使其分散性更好。当NAO负载量分别为80 mg/g和60 mg/g时,NAS对Se(Ⅳ)和Se(Ⅵ)的吸附性能为佳,分别需要60、120 min达到平衡,适应pH为2~5;两者均符合准2级动力学模型;NAS对Se(Ⅳ)、Se(Ⅵ)的最大吸附容量分别为137.2、143.9 mg/g,能很好地与Freundlich模型拟合,说明NAS表面不均匀,且属于多层吸附。经过2次的循环,对Se(Ⅳ)和Se(Ⅵ)的去除率有所降低,但均仍保持在一定的水平,说明NAS可再生循环利用。NAS作为一种新型吸附剂去除水中Se具有较好的应用前景。Liza Yu Chen LIN 何柳 刘通 王小■ 陈祥伟 解跃峰 2020水处理技术2020,46,1:2

9Effects of transdermal magnesium chloride on quality of life for patients with fibromyalgia: a feasibility study显示文摘BACKGROUND: Fibromyalgia is a syndrome characterized by chronic pain, fatigue, depression, and sleep disturbances. Its primary cause is unclear. Several studies have reported decreased intracellular magnesium levels in patients with fibromyalgia and have found negative correlation between magnesium levels and fibromyalgia symptoms.OBJECTIVE: To gather preliminary data on whether transdermal magnesium can improve quality of life for women who have fibromyalgia.DESIGN, SETTING, PARTICIPANTS AND INTERVENTIONS: This is a patient questionnaires and survey in a fibromyalgia clinic at a tertiary medical center. Forty female patients with the diagnosis of fibromyalgia were enrolled. Each participant was provided a spray bottle containing a transdermal magnesium chloride solution and asked to apply 4 sprays per limb twice daily for 4 weeks. Participants were asked to complete the Revised Fibromyalgia Impact Questionnaire, SF-36v2 Health Survey, and a quality-of-life analog scale at baseline, week 2, and week 4.MAIN OUTCOME MEASURE: Questionnaire and survey scores, evaluated through intent-to-treat and per-protocol analyses.RESULTS: Twenty-four patients completed the study(mean [SD] age, 57.2 [7.6] years; white, 95%; mean body mass index, 31.3 kg/m2). With intention-to-treat analysis, Revised Fibromyalgia Impact Questionnaire subscale and total scores were significantly improved at week 2 and week 4(total score, P = 0.001). Per-protocol analysis results were similar: all subscales of the Revised Fibromyalgia Impact Questionnaire were significantly improved at week 2 and week 4(total score, P = 0.001). CONCLUSION: This pilot study suggests that transdermal magnesium chloride applied on upper and lower limbs may be beneficial to patients with fibromyalgia.TRIAL REGISTRATION: Clinical Trials.gov.ldentifier NCT01968772.Deborah J.Engen Samantha J.Mc Allister Mary O.Whipple Stephen S.Cha Liza J.Dion Ann Vincent Brent A.Bauer Dietlind L.Wahner-Roedler 2015Journal of Integrative Medicine2015,13,5:2
