Abstract Lagostomus maximus is a notable mammalian model for reproductive studies. Females have
an extremely high ovulation rate, which is due to down-regulation of the follicular apoptosis pathway, which
ensures a large pool of developing follicles. This large pool is supported by the convoluted anatomy of the
mature ovary, whose germinal tissue is found in irregularly curved ridges throughout the cortex. Medullary
tissue is restricted to a minimum. Lyso Tracker Red reconstruction under confocal laser scanning microscopy
was used to recognize and measure all follicular stages from primordial to antral. Unlike most mammals in
which early primordial follicles are just found… More >

Abstract MicroRNAs (miRNAs) are short RNA molecules that negatively regulate gene expression
primarily by degrading target mRNA or inhibit the translation of protein product. Recently, many reports
have shown the altered miRNA expression in various diseases. However, there are no reports on miRNA
expression related to periodontitis. Thus, this study aimed to compare the miRNAs differentially expressed in
healthy and chronic periodontitis tissues and to determine the miRNAs closely associated with chronic periodontitis. To find out the miRNAs differentially induced in healthy and chronic periodontitis tissues, miRNA
microarray was carried out and the expression of miRNAs was confirmed by real-time PCR.… More >

Abstract The embryological, structural and functional unit of the dentine-pulp complex shares the odontoblast, located in the border of the dentine pulp, with basal nuclei and organelles. The odontoblast process
emerges from its apical pole. It is formed by microtubules, microfilaments and vesicles covered by membranes penetrating the dentinal tubules, isolated from the inter-tubular matrix, along the extent of the dentine.
The objective of this study was to evaluate the efficacy of three staining techniques: hematoxylin-eosin,
periodic acid-Schiff and Schmorl, by staining the process, from beginning to end, and compare the results
with the erosion technique. Thirty human teeth were employed… More >
