    Notes: This article presents a review of the state of the art of research and development on Hg1−xCdxTe -Hg1−yCdyTe (0≤x,y≤1) heterostructures important for applications in the modern infrared detection technique. It deals with the fundamental physical properties, epitaxial growth methods, and applications of these structures. The most important experimental results relevant to this subject are described and discussed. Following a short survey of the physical properties of Hg1−xCdxTe, the travelling heater method for growing bulk crystals of Hg1−xCdxTe has been described and compared with the epitaxial growth techniques used to prepare thin films and layered structures of this compound. Some important aspects of substrate preparation procedures related to CdTe wafers have been discussed. Then the most important problems regarding the liquid-phase, vapor-phase, and molecular-beam-epitaxy methods of Hg1−xCdxTe -Hg1−yCdyTe (0≤x,y≤1) heterostructures have been studied. A comprehensive discussion of technology and the parameters of different heterostructure photodiodes made of Hg1−xCdxTe with electrically passive and electrically active heterointerfaces has been presented. The review is concluded with an overview of research problems relevant to HgTe-CdTe superlattices and the surfaces and heterointerfaces of Hg1−xCdxTe.

    Notes: Thermal desorption experiments concerning Te deposits on GaAs (100) surfaces have been performed using quadrupole mass spectrometry. The results give evidence that near the GaAs surface two regions of different Te adsorption can be distinguished. The first region nearest to the substrate surface consists of Te adparticles, which are chemisorbed to the substrate reevaporating at temperatures above 510–520 °C. The adparticles of the second physisorbed region begin to desorb at 350–360 °C, which is still considerably higher than the desorption temperature of the bulk Te deposits. The approximate thicknesses of these two regions are 1–2 monolayers and 3–10 monolayers of Te, respectively.

    Notes: Abstract— Non-histone chromosomal proteins (NHCP) from mouse brain at different stages of development and from adult liver and kidney of strain related mice were analyzed by SDS-polyacrylamide gel electrophoresis and were compared with the mouse teratoma, OTT-6050. The fetal, neonatal and adult brains were qualitatively similar in their NHCP profiles but had quantitative differences. The NHCP composition of the adult brain was clearly distinct from that of the liver and kidney and was dissimilar from that of the teratoma.

    EFFECTS OF OSMOLAR CHANGES ON ISOLATED MITOCHONDRIA OF BRAIN AND LIVER (1978)

    Notes: Abstract— The effects of altered osmolarity on respiration and fine structure were compared in isolated rat cerebral versus liver mitochondria.Polarographic study of cerebral mitochondria in hypo-osmolar media showed inhibition of State 3 (ADP-dependent) respiration which was not reversed by dinitrophenol. In hyperosmolar media, State 3 respiration was transiently inhibited and State 4 (ADP-independent) respiration increased with the NAD-linked substrate pair, glutamate and malate. With succinate as substrate, respiration was not affected by moderate hyperosmolarity. In the most hyperosmolar medium, State 3 respiration was inhibited with both substrates.In contrast to the results with cerebral mitochondria, State 4 respiration was increased in hypo-osmolar media and State 3 respiration was persistently inhibited in hyperosmolar media in liver mitochondria with both substrates.In both cerebral and liver mitochondria, cytochrome c oxidase (EC 1.9.3.1.) activity was mildly inhibited in hypo-osmolar media and increased in hyperosmolar media.Electron microscopy showed that liver mitochondria were swollen in hypo-osmolar media and condensed in hyperosmolar media. Cerebral mitochondria showed mild rarefaction in hypo-osmolar media and, in hyperosmolar media, more than half the mitochondria showed either no or minimal changes in fine structure.Our results suggest that there are differences in metabolic control and structure between mitochondria from different cell types, which may be important in the cellular metabolic response to pathologic changes in water or osmolarity.

    Neuroendocrine evidence for serotonin receptor hypersensitivity in panic disorder (1988)

    Notes: Abstract Normal controls (NC) (n=15), patients with panic disorder (PD) (n=13) and patients with major depression (MD) (n=17) were challenged with a single, oral dose (0.25 mg/kg) of the selective 5HT agonist m-chlorophenyl-piperazine (MCPP) or placebo. Blood samples were assayed for cortisol and MCPP levels every 30 min. The PD group had an augmented cortisol release when compared to the other two groups. Finally, a significant correlation was found across all subjects between clinical anxiety level and cortisol release on MCPP. These data support the hypothesis of 5HT receptor hypersensitivity in PD.

    S-Antigen immunoreactivity in human pineal glands and pineal parenchymal tumors. A monoclonal antibody study (1986)

    Notes: Summary Using a four-step immunoperoxidase (PAP) method and the monoclonal antibody MAbA9-C6 (MAbA9-C6), which defines an epitope of the retinal S-antigen (S-Ag), we investigated the S-Ag immunoreactivity in human fetal, newborn, infantile and adult pineal glands and in 13 human pineal parenchymal tumors. S-Ag immunoreactivity was demonstrated in a few cells in one of the four fetal and in both infantile glands. Eight of nine adult pineal glands contained isolated MAbA9-C6-positive cells. In two of seven pineocytomas showing neuronal or gangliogliomatous differentiation a few scattered cells displayed S-Ag positivity; two of four pineoblastomas contained small groups of strongly immunoreactive neoplastic cells; two malignant pineocytomas did not demonstrate any S-Ag immunoreactivity. Our results indicate that isolated cells in human pineal gland retain some of the cytochemical characteristics of photoreceptor cells recognized by the MAbA9-C6, and that S-Ag immunoreactivity may be occasionally expressed in pineal parenchymal tumors.

    The astroblastoma and its possible cytogenic relationship to the tanycyte (1989)

    Notes: Summary Two examples of cerebral astroblastoma have been studied by electron microscopy and immunohistochemistry, one of them having been maintained in vitro in an organ-culture matrix system for 8 months and the explants studied by light and electron microscopy at different time intervals. The fine structural characteristics were those of a glial cell type with features intermediary between those of astrocytes and ependymocytes. They recapitulated the structure of the tanycyte, a glial precursor cell which is normally found scattered along the ependymal lining of the embryonal and neonatal mammalian brain, but is distinct from epithelial ependymocytes. The possible origin of some astroblastomas from such a cell would account for a number of characteristics in this enigmatic type of glioma.
