Spindle cell lipoma in the gingiva of a dog:a case report
oral cavity spindle cell lipoma CD34 vimentin oestrogen receptor
2015/7/28
Spindle cell lipoma is a benign lipomatous tumour that mainly occurs in the subcutis of the head, neck, and shoulder in elderly men. Oral spindle cell lipoma is extremely rare in all species, and no c...
Contribution of non-centrosomal microtubules to mitotic spindle assembly in mammalian cells
Mammalian cells bipolar spindle and chromosome microtubule mammals bipolar spindles
2014/12/11
In mammalian cells, the formation of a bipolar spindle is an essential process as any mistake in the segregation of chromosomes can result in aneuploidy, an outcome that can be detrimental to the orga...
The Fanconi anemia signaling network regulates the mitotic spindle assembly checkpoint
cancer mitosis cell division
2015/5/21
anconi anemia (FA) is a heterogenous genetic syndrome characterized by progressive bone marrow failure, aneuploidy, and cancer predisposition. It is incompletely understood why FA-deficient cells deve...
Low cogging torque and high efficient 3-phase spindle motors by reshaping magnetic circuit profiles
2011/11/29
The dynamic characteristics of a 3-phase spindle motor with 12-poles and 9-slots can be improved by reshaping the magnetic circuit profiles. The stator cores were designed with different ratios of x/y...

In the determination of the process accuracy on CNC lathe it is very important to know the thermal deformations. This article presents a new solution to obtain the thermal deformations at the principa...
两级先导式电磁阀主阀芯动力学分析（Dynamic Analysis of a Spindle of Pilot-operated Solenoid Valve）
动力系统 电磁阀 动力学模型
2009/5/22
对动力系统用两级先导式电磁阀进行了动力学分析。建立了基于电磁阀阀芯振动与流体流动相耦合的系统动力学模型。模型充分考虑了阀芯自激振动，阀内各腔以及阀前后管路内压力变化。分析了不同工作条件下阀芯的稳定性，研究了工作压力、工作流量对电磁阀动力学特性的影响。
Regulatory Mechanism of Spindle Movements during Oocyte Meiotic Division
Spindle Movement Meiotic Division Cytoskeleton Oocyte
2016/5/3
Female germ cell meiotic divisions are typically asymmetric, giving rise to two daughter cells with different sizes. Spindle movements including spindle migration from the oocyte center to the cortex ...
