CAN MATURATION ARREST OCCUR AT THE STAGE OF SPERMIOGENESIS?
Archives of Andrology, 2001This article attempts to clarify the pathological condition during which the maturation of the germinal epithelium is unable to evolve beyond a certain stage and is characterized as maturation arrest. Emphasis is given to the histological entity named spermiogenic arrest.

Proteomics of Secretory-Stage and Maturation-Stage Enamel of Genetically Distinct Mice
Caries Research, 2016The mechanisms by which excessive ingestion of fluoride (F) during amelogenesis leads to dental fluorosis (DF) are still not precisely known. Inbred strains of mice vary in their susceptibility to develop DF, and therefore permit the investigation of underlying molecular events influencing DF severity.

Phenolic Composition of Strawberry Genotypes at Different Maturation Stages
Journal of Agricultural and Food Chemistry, 2004The effects of maturation (green, pink, and ripe) on phenolic composition of strawberry cultivars Camarosa, Dorit, Chandler, and Osmanli and their hybrids were investigated using a high-pressure liquid chromatography (HPLC) method. p-Hydroxybenzoic acid, p-coumaric acid, ellagic acid, cyanidin-3-glucoside, pelargonidin-3-glucoside, kaempferol ...

Stages of textural maturity in sedimentary rocks
Journal of Sedimentary Research, 1951ABSTRACT Four stages of textural maturity in sediments are defined by the occurrence of three sequential events (1) removal of clays, (2) sorting of the sand fraction, and (3) attainment of high roundness. A binomial terminology is introduced wherein the term denoting textural maturity is prefixed to the rock-composition name, obtained from the ...

PGCCDBS Guidelines for Workshops on Maturity Staging
2010The main objectives of a maturity staging workshop are: i) to agree on a common maturity scale for the species/stock of concern across laboratories, based on a comparison of existing scales and standardization of maturity determination criteria; ii) to establish correspondence between old and new scales so that time series of previous data can be ...
