Immunohistochemical Localization of Progesterone Receptors in the Non-pregnant One-humped Camel Uterus

The current study aimed to localize immunohistochemically the cellular progesterone receptors in the non-pregnant one-humped camel uterus. Uterine tissue specimens from 10 she-camels during estrous were collected from local slaughterhouses and prepared for indirect immunoperoxidase staining using primary antibody for human progesterone receptor PR (clone 10A9). Nuclear signals for progesterone receptors were clearly observed in the uterine surface epithelium, glandular epithelium, myometrium, uterine stroma and in walls of some large blood vessels. The staining intensity was variable at different uterine tissue regions. Strong signals were demonstrated in the superficial gland zone, in the connective tissue stroma and in the myometrium. However, Nuclear signals of moderate intensity were noticed in the surface epithelium, deep gland zones and in the walls of the uterine arteries. No cytoplasmic signals could be detected. The current study concluded that nuclear signals for progesterone receptors were found in uterine surface epithelium, uterine glands, myometrium, uterine blood vessels and stroma

Structural and Optical Properties of Znse1−Xtex Nanocrystalline Thin Films in Terms of Optical Spectroscopic Ellipsometry

Polycrystalline thin films of ZnSe1−xTex (0.0 ≤ x ≤ 1.0) were deposited on glass substrate using electron beam deposition technique. The structure of the prepared films was examined using X-ray diffraction technique and revealed that the deposited films have polycrystalline zinc blend structure. The optical constants and film thicknesses of nanocrystalline ZnSe1−xTex films were obtained by fitting the spectroscopic ellipsometric data (ψ, Δ) using a three-layer model system in the wavelength range from 400 to 1100 nm. The refractive index was observed to increase with increasing Te concentration. This increase in the refractive index with increasing Te content may be attributed to the increase in the polarizability due to the large ionic radius of Te compared to the ionic radius of Zn. The optical studies of the polycrystalline ZnSe1−xTex films showed that the refractive index increases, and fundamental band gap opt g E decreases from 2.58 to 2.21 eV as the tellurium concentration increases from 0 to 1. Furthermore, it was also found that the variation of optical band gap with composition shows quadratic behavior
