| 1 | Shot-noise limited, supercontinuum-based optical coherence tomography显示文摘We present the first demonstration of shot-noise limited supercontinuum-based spectral domain optical coherence tomography(SD-OCT)with an axial resolution of 5.9μm at a center wavelength of 1370 nm.Current supercontinuumbased SD-OCT systems cannot be operated in the shot-noise limited detection regime because of severe pulse-topulse relative intensity noise of the supercontinuum source.To overcome this disadvantage,we have developed a low-noise supercontinuum source based on an all-normal dispersion(ANDi)fiber,pumped by a femtosecond laser.The noise performance of our 90 MHz ANDi fiber-based supercontinuum source is compared to that of two commercial sources operating at 80 and 320 MHz repetition rate.We show that the low-noise of the ANDi fiber-based supercontinuum source improves the OCT images significantly in terms of both higher contrast,better sensitivity,and improved penetration.From SD-OCT imaging of skin,retina,and multilayer stacks we conclude that supercontinuumbased SD-OCT can enter the domain of shot-noise limited detection. | Shreesha Rao D.S.

| 13 | 注意力缺陷/多动症和儿童期自闭症与产前暴露于全氟烷基物质之间的关联:丹麦全国出生队列的一项巢式病例对照研究显示文摘[背景]全氟烷基物质(PFASs)是持久性污染物,动物实验中具有内分泌干扰性和神经毒性。一些横断面数据显示PFASs与儿童神经行为的问题之间存在正向关联,但是来自前瞻性研究的结果仍然有限。[目的]研究产前暴露于PFASs是否与儿童中的注意力缺陷/多动障碍(ADHD)或儿童期自闭症之间有关联。[方法]在1996—2002年丹麦全国出生队列的83 389对母子中,根据丹麦国家医院登记和丹麦精神病中心登记,确定了890名ADHD病例和301名儿童自闭症病例。从这个队列中,随机各选择220例多动症和自闭症病例,并随机选择550例性别相匹配的对照儿童。测量在妊娠早期或中期采集的母体血浆中16种PFASs,使用广义线性模型计算风险比(RRs),模型中考虑到了抽样权重。[结果]在所有样品中均检测到全氟辛烷磺酸(PFOS)和全氟辛酸(PFOA),在≥90%的样本中可以定量其他4种PFASs。没有发现母亲PFAS血浆水平和ADHD之间关联的一致性证据[浓度(ng/m L)的自然对数值每增加一个单位,PFOS对应的RR=0.87(95%CI:0.74,1.02),PFOA对应的RR=0.98(95%CI:0.82,1.16)],对于自闭症也是如此[浓度(ng/m L)的自然对数每增加一个单位,PFOS对应的RR=0.92(95%CI:0.69,1.22),PFOA对应的RR=0.98(95%CI:0.73,1.31)]。在同时校正所有PFASs的模型中,较高的PFAS分位数和ADHD之间既有阳性关联也有阴性关联,但是这些关联的估计值并不精确。[结论]在这项研究中,没有发现一致性的证据能够提示产前PFAS暴露增加儿童中ADHD或儿童期自闭症儿的风险。 | Zeyan Liew Beate Ritz Ondine S.von Ehrenstein Bodil Hammer Bech Ellen Aagaard Nohr Chunyuan Fei Rossana Bossi Tine Brink Henriksen Eva Cecilie Bonefeld-Jφrgensen Jφrn Olsen | 2015 | 环境与职业医学2015，32，10： | 1 |
