As part of a comparative morphological study, the fine structure of the retinal epithelium (RPE), choriocapillaris and Bruch's membrane (complexus basalis) has been investigated by light and electron microscopy in the galah (Eolophus roseicapillus), an Australian cockatoo. The RPE consists of a single layer of low cuboidal cells joined basally by a series of zonulae occludentes. Basally (sclera...

BACKGROUND The aim of this study was to investigate the percentage of the stem cells population in human endometrial tissue sections and cultured cells at fourth passage. METHODS Human endometrial specimens were divided into two parts, one part for morphological studies and the other part for in vitro culture. Full thickness of human normal endometrial sections and cultured endometrial cells ...

Uterine vascular changes, critical for pregnancy success, occur at each implant site during endometrial decidualization. Mesometrial decidualization recruits high numbers of angiogenic, uterine Natural Killer (uNK) cells that trigger midpregnancy spiral arterial remodeling. We postulated that uNK cells contribute to early decidual angiogenesis as endothelial-cell extrinsic sources of Delta-like...

By gel filtration on a Fractogel TSK HW 50 column followed by cation-exchange chromatography on CM-Trisacryl M, a tetradecapeptide amide, designated 'mastoparan B', was purified from the venom of the hornet Vespa basalis. Its amino acid sequence was determined as: Leu-Lys-Leu-Lys-Ser-Ile-Val-Ser-Trp-Ala-Lys-Lys-Val-Leu-NH2 and its molecular mass was measured to be 1611 Da by fast-atom-bombardme...

BACKGROUND The morphological changes occurring during the dynamic process of menstruation have previously been described only in terms of data derived from static sources, including histological and electron microscopic studies. Recent advances in pressure-controlled, continuous flow hysteroscopy permit dynamic images to complement the traditional modalities. METHODS A prospective observation...

An auditory projection to the frontolateral telencephalon of birds, originally described by Iljitschew, is confirmed for the pigeon. Potentials evoked by acoustic stimuli were recorded from the neostriatum frontale closely surrounding the nucleus basalis, in anesthetized and awake subjects. The latency of these responses was short (5 to 8 ms) compared to that of responses recorded from the orth...

Characterization and evaluation of the activity of Vespa basalis DPP-IV, which expressed in Spodoptera frugiperda 21 cells. The expression of rDPP-IV was confirmed by SDS–PAGE, Western blot analyses, LC-MS/MS and measurement of its peptidase specificity. One-step purification by Ni-NTA affinity chromatography and the total amount of rDPP-IV recovered was approximately 6.4mg per liter from infec...

Rare cells with adult stem cell activity were recently discovered in human endometrium. Endometrial stem/progenitor cell candidates include epithelial, mesenchymal and endothelial cells, and all may contribute to the rapid endometrial regeneration following menstruation, rather than a single candidate. Endometrial mesenchymal stem-like cells (eMSC) are prospectively isolated as CD146+PDGF-Rb+ c...

We examined the projection from the basal forebrain to thalamic and cortical regions of the visual system in cats, with particular reference to the visual sector of the thalamic reticular nucleus, the lateral geniculate nucleus, and the striate cortex. First, we made injections of wheat germ agglutinin conjugated to horseradish peroxidase (WGA-HRP) into the visual sector of the thalamic reticul...
