Abstract The testis is a double gland comprised of the sperm-producing seminiferous tubules and a complex endocrine interstice. The former structures generate and release whole cells (exocrine aspect of the gland) while the latter synthesize and release androgens and related hormones. The testis also has poorly understood paracrine connexions. These connexions play an important role during spermatogenesis. A key molecule within these structures is β-actin. Therefore, the present study aims at examining the expression pattern of β-actin during the various stages of the spermatic cycle in the rat. To achieve this goal, we used a combination of trans-illumination assisted microdissection of… More >

Abstract The material point method (MPM), which is an extension from computational fluid dynamics (CFD) to computational solid dynamics (CSD), is improved for the coupled CFD and CSD simulation of the zona failure response in piezo-assisted intracytoplasmic sperm injection (piezo-ICSI). To evaluate the stresses at any zona material point, a plane stress assumption is made in the local tangent plane of the membrane point, and a simple procedure is proposed to find the effective point connectivity for the orientation of the local tangent plane. With an iterative algorithm in each time step, the original MPM is improved to better simulate fluid… More >
