The teratogenicity of 5-fluoro-2'-deoxyuridine (FdU) is well established. Previously, we have demonstrated that teratogenic doses of FdU produce hematomas and suggested that those hematomas produced skeletal malformations in chicken embryos. In this study, the cardiovascular effects of teratogenic doses of FdU in chicken embryos were studied. A dose of either 0.026 μg FdU or 0.030 μg FdU was injected into the yolk sacs of fertile chicken eggs containing embryos at Hamburger and Hamilton stages 17-19 of development. The embryos were then returned to the incubator. Aortic systolic and diastolic blood pressure,blood velocity and heart rate were measured at stages 21, 24 or 27 using a servonull system and doppler ultrasound. In addition, mean arterial blood pressure, blood flow, and stroke volume were calculated from these data. Similar data were also recorded from uninjected and saline injected control embryos. Systolic and mean arterial blood pressures were significantly increased in FdU-treated embryos at stage 27. The other parameters measured or calculated were not significantly different from control embryos. Our study suggests that elevated systolic blood pressure in chicken embryos treated with FdU may lead to hematoma formation and subsequent birth defects

Introduction: Rheumatoid arthritis (RA) is the most common chronic inflammatory rheumatism. The increasing use of bone and joint ultrasound as a tool to aid in the detection of unrefined synovitis in developed countries, has led us to study the performance of ultrasound in the diagnosis of RA in subjects consulting in rheumatology at cotonou. Study Method: descriptive cross-sectional study of patients with RA, selected on the basis of AcR/ EULAR 2010 criteria. A complete clinical examination with imaging including X-rays and ultrasounds of the hands and feet were performed in all patients who have given their consent. The data collected was analyzed using EPI data 3.1 and SPSS 24.0 software. The significance rate was defined with a p-value cohen’s Kappa (k) test was used to assess agreement. Results: All 53 patients included had lesions on ultrasound. Synovitis was found in 98.1% and bone erosions in 88.7%. There was no agreement in the wrists between clinical examination and ultrasound (k = -0.116), McP (k = -0.097) and MTP (k = -0.031). Agreement was very low at the PPI level (k = 0.03). It was low at the different sites, between ultrasound and radiographic detection of lesions (k between 0.022 - 0.22). Age, positive immunologic RA factor and biological inflammatory syndrome were associated with ultrasound erosions (p = 0.0001) and only age was associated with active synovitis (p = 0.022). conclusion: Bone and articular ultrasound is a good complementary alternative to clinical examination and radiography diagnostic in early diagnosis of RA in our developing countries, in the absence of MRI which remains a luxury.

一根轴向运动弦的横向振动稳定性是通过随时间变化的,使用对边界的横向运动或者外部的边界力的控制来实现的。平移弦的全部机械能量是一个亚普诺夫函数,边界控制法则被设计用于分散弦的整个振动能量在左侧或者右侧的边界。一种最佳的反馈可通过降低受边界条件影响的能量获得,是边界控制的张力与入射波的传播速率的比值。同样,所需的最大时间用来稳定系统中的最初的扰动造成的全部振动能量,就是波在弦的跨度范围内在撞击边界之前传播所需要的时间。通过能量准则的衰减比率和半群理论的使用,边界控制下的轴向运动弦的渐近线和指数稳定性被分析验证。模拟被用于证实平移弦稳定性的理论预测和最优边界控制。

New radiolarian ages show that the island arc-related Acoje block of the Zambales Ophiolite complex is possibly of Late Jurassic to Early cretaceous *** dating of its plutonic and volcanichypabyssal rocks yielded middle Eocene *** the other hand,the paleontological dating of the sedimentary carapace of the transitional mid-ocean ridge-island arc affiliated coto block of the ophiolite complex,together with isotopic age datings of its dikes and mafic cumulate rocks,also yielded Eocene *** offers the possibility that the Zambales Ophiolite complex could have:(1)evolved from a Mesozoic arc(Acoje block)that split to form a cenozoic back-arc basin(coto block),(2)through faulting,structurally juxtaposed a Mesozoic oceanic crust with a younger cenozoic lithospheric fragment or(3)through the interplay of slab rollback,slab break-off and,at a later time,collision with a microcontinent fragment,caused the formation of an island arc-related ophiolite block(Acoje)that migrated trench-ward resulting into the generation of a back-arc basin(coto block)with a limited subduction *** Meso-cenozoic ophiolite complex is compared with the other oceanic lithosphere fragments along the western seaboard of the Philippines in the context of their evolution in terms of their recognized environments of generation.
