4Updates in advanced diffusion-weighted magnetic resonance imaging techniques in the evaluation of prostate cancer显示文摘Diffusion-weighted magnetic resonance imaging(DWMRI) is considered part of the standard imaging protocol for the evaluation of patients with prostate cancer.It has been proven valuable as a functional tool for qualitative and quantitative analysis of prostate cancer beyond anatomical MRI sequences such as T2-weighted imaging. This review discusses ongoing controversies in DW-MRI acquisition, including the optimal number of b-values to be used for prostate DWI, and summarizes the current literature on the use of advanced DWMRI techniques. These include intravoxel incoherent motion imaging, which better accounts for the nonmono-exponential behavior of the apparent diffusion coefficient as a function of b-value and the influence of perfusion at low b-values. Another technique is diffusion kurtosis imaging(DKI). Metrics from DKI reflect excess kurtosis of tissues, representing its deviation from Gaussian diffusion behavior. Preliminary results suggest that DKI findings may have more value than findings from conventional DW-MRI for the assessment of prostate cancer.Hebert Alberto Vargas Edward Malnor Lawrence Yousef Mazaheri Evis Sala 2015World Journal of Radiology2015,7,8:11
5Acute effects of physical exercise in type 2 diabetes: A review显示文摘The literature has shown the efficiency of exercise in the control of type 2 diabetes(T2D), being suggested as one of the best kinds of non-pharmacological treatments for its population. Thus, the scientific production related to this phenomenon has growing exponentially. However, despite its advances, still there is a lack of studies that have carried out a review on the acute effects of physical exercise on metabolic and hemodynamic markers and possible control mechanisms of these indicators in individuals with T2 D, not to mention that in a related way, these themes have been very little studied today. Therefore, the aim of this study was to organize and analyze the current scientific production about the acute effects of physical exercise on metabolic and hemodynamic markers and possible control mechanisms of these indicators in T2 D individuals. For such, a research with the following keywords was performed:-exercise; diabetes and post-exercise hypotension; diabetes and excess post-exercise oxygen consumption; diabetes and acute effects in PUBMED, SCIELO and HIGHWIRE databases. From the analyzed studies, it is possible to conclude that, a single exercise session can promote an increase in the bioavailability of nitric oxide and elicit decreases in postexercise blood pressure. Furthermore, the metabolic stress from physical exercise can increase the oxidation of carbohydrate during the exercise and keep it, in high levels, the post exercise consumption of O2, this phenomenon increases the rate of fat oxidation during recovery periods after exercise, improves glucose tolerance and insulin sensitivity and reduces glycemia between 2-72 h, which seems to be dependent on the exercise intensity and duration of the effort.Ricardo Yukio Asano Marcelo Magalhes Sales Rodrigo Alberto Vieira Browne José Fernando Vila Nova Moraes Hélio José Coelho Júnior Milton Rocha Moraes Hebert Gustavo Simoes 2014World Journal of Diabetes2014,5,5:8
6基于人工智能的前列腺癌影像的现状与展望显示文摘在前列腺癌影像中,人工智能(AI)在执行3个主要临床任务中具有较大实用价值,包括前列腺癌的检测、表征(肿瘤和器官的分割、诊断和分期、预后和结果预测等)和监视。尽管AI在前列腺癌影像中取得了巨大成功,但在AI广泛临床应用之前还必须克服一些限制和障碍。期望未来临床医师可以基于AI技术分析的结果进行决策。王良 陈敏 Li Qiubai Hebert Alberto Vargas 2019中华放射学杂志2019,53,10:7

8口服低衰减胃肠道造影剂在腹盆部CT中的应用显示文摘Background: We designed and evaluated a low-attenuation oral contrast agent for abdominal-pelvic computed tomography (CT). Methods: In vitro studies, were performed initially to evaluate the imaging characteristics of multiple solutions. These studies resulted in two solutions being compared with the presently accepted oral CT agents of dilute iodinated contrast and water. Ninety-eight consec utive subjects already scheduled for routine outpatient abdominal-pelvic CT were enrolled. Subjects were randomized to water (n = 30), fiber solution (n = 32), polyethylene glycol (PEG; n = 11), or dilute iodinated solution (DI; n = 25). Examinations were then evaluated for gastric distention, small bowel distention, small bowel wall visualization, and colonic transit. A questionnaire was given to the study subjects for feedback concerning taste and potential side effects from these agents. Results: PEG tended to provide better bowel distention, wall visualization, and colonic transit compared with water, fiber solution, and DI. Areas of statistical significance included: (1) average bowel diameter in the left upper quadrant for water was 17.50 mm, whereas that for PEG was 21.88 mm (p < 0.05); (2) average bowel diameter in the pelvis for water was 14.79mm, that for fiber was 15.67mm, and that for PEG was 18.48 mm (p < 0.05); (3) wall visualizati on was better with PEG than with fiber (p < 0.05); (4) successful transit of contrast to the colon occurred in every subject who received PEG compared with only 20%of those received water and 39%of those who received fiber (p < 0.05). Similar trends for the superiority of PEG over DI were noted, although many of these did not reach statistical significance. Conclusion: PEG solution has imaging characteristics related to bowel wall visualization, luminal distention, and colonic transit that make it an effective oral agent for abdominal pelvic CT examination.Hebert J.J Taylor A.J Winter T.C. 赵双 2006世界核心医学期刊文摘(胃肠病学分册)2006,0,4:5

10Imaging shallow structure with active-source surface wave signal recorded by distributed acoustic sensing arrays显示文摘Distributed acoustic sensing(DAS) is one recently developed seismic acquisition technique that is based on fiber-optic sensing. DAS provides dense spatial spacing that is useful to image shallow structure with surface waves.To test the feasibility of DAS in shallow structure imaging,the PoroTomo team conducted a DAS experiment with the vibroseis truck T-Rex in Brady's Hot Springs, Nevada, USA.The Rayleigh waves excited by the vertical mode of the vibroseis truck were analyzed with the Multichannel Analysis of Surface Waves(MASW) method. Phase velocities between5 and 20 Hz were successfully extracted for one segment of cable and were employed to build a shear-wave velocity model for the top 50 meters. The dispersion curves obtained with DAS agree well with the ones extracted from co-located geophones data and from the passive source Noise Correlation Functions(NCF). Comparing to the co-located geophone array, the higher sensor density that DAS arrays provides help reducing aliasing in dispersion analysis, and separating different surface wave modes. This study demonstrates the feasibility and advantage of DAS in imaging shallow structure with surface waves.Zhenghong Song Xiangfang Zeng Clifford H.Thurber Hebert F.Wang Dante Fratta 2018Earthquake Science2018,31,4:4
11以让患者满意为终极目标,推动膀胱疾病影像学的规范化发展显示文摘在我国膀胱癌是第12位的常见恶性肿瘤,但不同医疗机构膀胱疾病的诊断水平差异较大,膀胱影像报告和数据系统(VI-RADS)有助于指导和统一膀胱疾病诊断流程。VI-RADS对膀胱多参数MRI(mpMRI)检查设备和技术要求提出了指导性建议,对MRI设备、技术规范、扫描参数及评估分类标准制定了规范,适用于未治疗的患者和接受过诊断性经尿道膀胱肿瘤切除术的患者。VI-RADS强调mpMRI克服了CT的局限性,改善了膀胱癌的诊断和准确分期;除mpMRI检查外,CT尿路成像或MR尿路成像、CT、双能量CT、超声检查等方法在膀胱癌的诊断、定位和分期中也有一定价值。VI-RADS的制定有助于推动膀胱mpMRI检查的规范化、标准化,提高膀胱mpMRI的诊断、分期、侵袭性预测和疗效评估。王良 Li Qiubai Hebert Alberto Vargas 2019中华放射学杂志2019,53,3:3

20Axial strain enhances osteotomy repair with a concomitant increase in connexin43 expression显示文摘The mechanical environment is known to influence fracture healing. We speculated that connexin43(Cx43) gap junctions, which impact skeletal homeostasis, fracture healing and the osteogenic response to mechanical load,may play a role in mediating the response of the healing bone to mechanical strain. Here, we used an established rat fracture model, which uses a 2 mm osteotomy gap stabilized by an external fixator, to examine the impact of various cyclical axial loading protocols(2%, 10%, and 30% strain) on osteotomy healing. We examined the presence of Cx43 in the osteotomy-healing environment and assessed how mechanical strain modulates Cx43 expression patterns in the callus. We demonstrated that increased cyclical axial strain results in increased radiographic and histologic bone formation. In addition, we show by immunohistochemistry that Cx43 is abundantly expressed in the healing callus, with the expression most robust in samples exposed to increased cyclical axial strain. These data are consistent with the concept that an increase in Cx43 expression by mechanical load may be part of the mechanisms by which mechanical forces enhances fracture healing.Rishi R Gupta Hyunchul Kim Yu-Kwan Chan Carla Hebert Leah Gitajn David J Yoo Robert V O’Toole Adam H Hsieh Joseph P Stains 2015Bone Research2015,3,2:2
