Expression of Insulin-like Growth Factor-I in Uterusis Ovarian Steroid Dependent:An in situ Immunohistochemical Study in Rat

引用

Journal of Reproduction and Contraception 2012年第4期23卷 222-236页

作者： Daniel Mize Purba Jyoti Saikia Hirendra n Sarma Department of Zoology (Center with potential for excellence in Biodiversity) Rajiv Gandhi University

Objective To study the immunohistochemical localization of insulin-like growth factor- I （IGF-I） in rats＇ uteri to determine if expression of the growth factor is ovarian steroid dependent. The study was carried out in presence and absence of ovary in situ of non pregnant females and during early gestation （day 1 to day 5.5）. Cyclic females were tested to observe the effect of native steroids on IGF-I expression. Adult females were ovariectomized （OVX） and injected （s.c） with estradiol-1713 in a dose of O.1 I^g/ml per day for three consecutive days at interval of 24 h prior to the collection of uterine horns. During the early pregnancy, studies were carried out on day 3.5 and day 5. 5 of geatation respectively to determine the Steroids＇ effects during pre- and post-implantation period Tamoxifen was administered （s.c） in a dose of 250 Ug/ml per day from day 1 to day 3 of gestation while, the prostaglandin F2a （PGF2a） was administered （s.c） from day 3 of gestation onward for three consecutive days at interval of 24 h in a dose of 150 μg/ml per day. Expression of lGF-I was immunohistochemically localised using IGF-1 antibody in paraffin embedded sections. Results IGF-I was expressed in rat uterus during estrus phase as well as during pre and post-implantation period The ovariectomized females＇ uteri lost the expression of IGF-1. Exogenous administration of tamoxifen and PGF2a reduce the expression of the growth factor. Conclusion Expression of lGF-1 in rat uterus during cyclic stage and early gestation depends upon the availability of circulating estrogen and progesterone. Uterine expression of lGF-I can be modulated by manipulating circulating ovarian steroid either during cyclic stage or during gestation.

Wave scattering by undulating bed topography in a two-layer ocean

引用

Journal of Marine Science and Application 2009年第3期8卷 183-195页

作者： P. MAITI B. n. MAnDAL U. BASU Department of Mathematics Jadavpur University Physics and Applied Mathematics Unit Indian Statistical Institute Department of Applied Mathematics Calcutta University

The problem of wave scattering by undulating bed topography in a two-layer ocean is investigated on the basis of linear theory. In a two-layer fluid with the upper layer having a free surface, there exist two modes of waves propagating at both the free surface of the upper layer and the interface between the two layers. Due to a wave train of a particular mode incident on an obstacle which is bottom-standing on the lower layer, reflected and transmitted waves of both modes are created by the obstacle. For small undulations on the bottom of the lower layer, a perturbation method is employed to obtain first-order reflection and transmission coefficients of both modes for incident wave trains of again both modes in terms of integrals involving the bed-shape fimction. For sinusoidal undulations, numerical results are presented graphically to illustrate the energy transfer between the waves of different modes by the undulating bed.

Changing paradigms in lower extremity reconstruction in war-related injuries

Background: Ballistic high-energy trauma has substantially increased the severity of non-fatal extremity injuries incurred in modern warfare. Expedient medical care, refinement in surgical techniques, and soft tissue coverage have brought about a paradigm shift in the management of lower extremity wounds during the last decade with an increased emphasis on limb ***: A literature-based study was conducted to analyze reconstructive modalities based on the location, depth, and severity of wounds, as well as mechanism of injury, concomitant vascular injuries and open fractures, choice of flap, timing of definitive reconstruction, and ***: Extremity injuries account for over 60% of injuries in the recent conflicts in Iraq and Afghanistan, with the majority secondary to explosive devices. The severity of these injuries is profound compared with civilian registries, and conventional injury scoring systems have failed to accurately predict outcomes in combat trauma. The mainstay of treatment is serial debridement, negative pressure therapy, fracture stabilization, and treatment of concomitant injuries by the forward medical teams with subsequent definitive reconstruction after transport to an advanced military treatment facility. Autologous reconstruction with free tissue transfer and pedicled flaps remains the primary modality for soft tissue coverage in limb salvage. Adjunct innovative modalities, such as external tissue expansion, dermal substitutes, and regenerative matrices, have also been successfully utilized for limb ***: Lower extremity injuries account for the vast majority of injuries in modern warzones. Explosive devices represent the most common mechanism of injury, with blast impact leading to extensive soft tissue injuries necessitating complex reconstructive strategies. Serial debridement, negative pressure therapy, and autologous reconstruction with free tissue transfer and pedicled flaps remain the mainstay of t

以纳米结构Y2O3稳定的ZrO2热喷涂粉末为原料,采用等离子喷涂法在Ti-6Al-4V合金上制备了纳米结构的热障涂层。利用扫描电镜(SEM)及扫描热显微镜(SThM)对涂层的微观组织及热性能进行了分析。在实验基础上建立了理论模型,并对涂层及基体的热导率进行了估算。结果表明:采用SThM分析方法估算的涂层厚度及涂层上的缺陷尺寸与采用其它分析方法测得的结果一致;虽然热导率的估算结果与采用其它方法得出的结果差异较大,但显示出扫描热显微镜分析是估算材料热导率潜在的方法。

The effect of the Al-6Ce-3La（ACL） on the microstructural behavior of the Al7075 was investigated. Materials were synthesized by mechanical alloying with variation in the ACL content and milling time. Products were characterized and studied in the as-milled condition and mechanically evaluated after sintering. The synergetic effect of milling time and ACL content in the modified materials led to a reduction in the particle size. Results from electron microscopy showed a homogeneous dispersion of Ce/La phases up to 20 wt.% of ACL content after 10 h of milling. Mechanical evaluation under compressive test showed an improved performance for those alloys reinforced with 0.2 wt.% and 0.5 wt.% of ACL.
