Cells of mouse embryos develop a polarization of microvillous distribution at compaction. Cells of the 4-cell embryo show a uniform pattern of fluorescent-ligand binding and an even distribution of microvilli. Each cell of the early 8-cell embryo has a uniform distribution both of microvilli and of fluorescent ligand. During the 8-cell stage, there is a progressive increase in the incidence of cells which show microvilli restricted to a region normally on the exposed surface of the embryo. When late 8-cell embryos were disaggregated to single cells, and these sorted by pattern of fluorescent-ligand binding, each of the four patterns of staining related consistently to a characteristic distribution of microvilli as viewed by scanning electron microscopy. The 16-cell embryo possessed an inside population of uniformly labelled cells with a sparse microvillous distribution, and an outside population of cells, each of which had a microvillous pole.

Image Technique

By means of high resolution transmission electron microscopy (HREM) and high-angle annular dark-field image technique (HAADF), morphological, structural and compositional characteristics of the precipitates in the Mg-4Y-3Nd alloy aged at 200°C for different periods of time have been studied. On the basis of HREM observations, an atomic structural model for the β’-precipitate with an orthorhombic unit cell has been proposed. The characteristic distribution of the precipitates which are rich in rare-earth elements (Y, Nd) has been clearly revealed by the HAADF imaging technique.

Pathologic Findings

The clinical and pathologic findings in two male siblings with congenital myopathy are presented. The pathologic changes in both cases were identical to those seen in progressive muscular dystrophy. In one sibling, immobility of the joints and abnormalities of posture (arthrogryposis) were the striking clinical features. Where arthrogryposis is the result of myopathy, the abnormal postures have a characteristic distribution and appearance. The greatest amount of connective tissue was found in the muscles that were shortened, suggesting that fibrosis was the basis of the contracture. In the second sibling a hypotonic flaccid weakness, without contracture, was noted. The authors state that arthrogryposis multiplex congenita as well as congenital weakness with hypotonia may result from one of a number of disease states. This careful study of two siblings is important because of the possible relationship between arthrogryposis and the limp child with progressive muscular dystrophy.

Sequence Similarity Analysis

Similarity analysis of DNA sequences is a fundamental research area in Bioinformatics. The characteristic distribution of L-tuple, which is the tuple of length L, reflects the valuable information contained in a biological sequence and thus may be used in DNA sequence similarity analysis. However, similarity analysis based on characteristic distribution of L-tuple is not effective for the comparison of highly conservative sequences. In this paper, a new similarity measurement approach based on Triplets of Nucleic Acid Bases (TNAB) is introduced for DNA sequence similarity analysis. The new approach characterizes both the content feature and position feature of a DNA sequence using the frequency and position of occurrence of TNAB in the sequence. The experimental results show that the approach based on TNAB is effective for analysing DNA sequence similarity.

Renin Content

The effects were investigated in rats of unilateral renal ischemia, adrenalectomy and varying doses of cortexone on the development of hypertension and on the content of pressor substances in the kidney. Adrenalectomy prevented the hypertension which follows unilateral clamping of the renal artery when a life maintaining dose of 0.1 mg cortexone acetate was injected daily. However, administration of 75 mg cortexone in the form of implants restored but did not enhance the characteristic hypertensive response to renal ischemia. The characteristic distribution of renal pressor material, being normal in the clamped and diminished in the contralateral kidney, was no longer observed after adrenalectomy when only small doses of cortexone were given but was still evident when excess cortexone was given. Overdosage with cortexone without clamping a renal artery led only to a moderate reduction of pressor material in both kidneys while in animals with unilateral renal ischemia the pressor material (renin?) in the contralateral kidney disappeared completely. Clamping the renal artery prevented the diminution of pressor material in the ipsilateral kidney which otherwise occurs under overdosage with cortexone in the normal animal.
