... 24 Additionally, autoradiographic methods have been used. 25 All of these techniques have been applied to describe the morphologic aspects of dentin PG. [26][27][28][29] Recently an immunocytochemical approach has been proposed at the light microscopy level. 9 The aim of this research project was to identify the human dentin PG following different application times of a solution of 35% PA (and, as control specimen, after conditioning with EDTA at pH 7.0) by means of an immunocytochemical technique with high-resolution SEM. ...

... A transfer of radiosulphate from the maternal rat to the foetus was first reported by Layton et al. (1950). Bostrom & Odeblad (1953) briefly reported the incorporation of radiosulphate 1 A preliminary report on this subject appeared in Experientia, 10, (1954), 67. by rabbit embryos as revealed by autoradiography. The uptake of S 35 varied markedly in different tissues, being highest in those presumably containing sulpho-mucopolysaccharides. ...

... They hypothesized secretion of iron-rich materials from the glands into the uterine lumen from where the yolk sac endoderm absorbed the compounds. Subsequent physiological studies have indicated the yolk sac has at least some role in maternal-fetal transfer of iron (Nylander, 1953;Magnusson et al, 1955;Glasser et al, 1968;Kaufman and Wyllie, 1970;Garrett et al, 1972Garrett et al, , 1973. The relative importance of the yolk sac in iron transfer compared with the chorioallantoic placenta is the subject of some disagreement in the above-mentioned studies, perhaps due in part to variations in gestational age and to the form in which iron was administered. ...

... Information as to the penetration of chemicals into the granulosa cells and into the oocyte is scanty, although there is some evidence that these structures are also permeable to foreign chemicals (18)(19)(20). Moreover, Glass (16) has shown that albumin and a-globulin penetrate the oocyte, but that,8and y-globulins do not. ...

... Radioautography of rat mast cells has been utilized to show that sulfate is incorporated into heparin and then slowly lost. Approximately 75% of the heparin was found to be present after 18 days [50]. When ['4C]hyaluronic acid was injected into guinea pigs [51], most of the label was found to be excreted as hyaluronic acid with less being metabolized. ...

... 2) Apposition techniques with separate processing of tissue-containing slide and photographic emulsion-containing slide (Hoecker and Roofe, 1949;Williams, 1951;Magnusson and Odeblad, 1954;Oster et al, 1955;Sterling and Chichester, 1956;Huang, 1960;Novek, 1962;Werner et al, 1966). ...

... A number of applications have been proposed for scatter images. Because the intensity of the image is proportional to electron density, researchers proposed (Odeblad and Norhagen 1956) and showed (Lale 1959, Farmer and Collins 1971, Clarke et al 1976, Harding and Tischler 1986) that scatter images may be used to create volumetric electron density maps of 3D objects and tissues, although steps must be taken to reduce the contribution from multiple scattering (Farmer and Collins 1971) and correct for attenuation (Lale 1959, Clarke and Van Dyk 1973, Battista et al 1977. The high fluence (and resulting dose) required for these measurements and the development of kilovoltage computed tomography (CT) made scatter electron density mapping obsolete (Battista and Bronskill 1981). ...

... The latter takes into account the absorption of radiations, primarily aimed at the crystal, and the scattering toward the crystal of radiations primarily directed elsewhere. 20 As shown in figure 1, -(v) decreases as the longitudinal distance between the source and the counter increases. Lateral displacement of the source from the axis of the counter also decreases q (v). ...

... In 1956, Scandinavian gynaecologist Odeblad was the first physician to utilize NMR spectroscopy for the analysis of a reproductive fluid. He retrieved cervical mucus from apparently healthy women and using 1 H-NMR spectroscopy demonstrated changes in an unknown signal at different stages of the menstrual cycle (Odeblad and Bryhn, 1957). The authors postulated that this change was in response to estrogenic changes (Odeblad and Bryhn, 1957). ...

... Nuclear magnetic resonance (NMR) spectroscopy has proven to be a powerful tool for the analysis of milk and dairy products, given its unique ability to simultaneously detect and identify small molecules within complex matrices, such as milk [1]. NMR was initially employed by Odeblad and Westing in the 1950s to investigate milk properties and allowed the identification of distinct components of human milk: lactose from milk plasma and milk fat [2]. Since then, NMR spectroscopy has been extensively utilized in various studies, providing valuable insights into the composition, structure, and properties of milk, including the content of key components such as fat, protein, lactose, and minerals. ...
