Background: Different culture media are used for in vitro maturation of ovine oocyte. The Weymouth medium are used for in vitro maturation of rat and mice oocytes with very low levels of supplementation (Just FBS, while to acquire the good results in TCM hormone, and serum supplementation and in some cases growth factor are necessary to gain the optimized results. The aim of the present study w...

In this paper, we investigate a linear population model of cells that are capable of simultaneous proliferation and maturation. We consider the case when the time required for a cell to divide depends on its maturity. This model is described by first order partial differential system with a retardation of the maturation variable and a time delay depending on this maturity. Both delays are due t...

increasing product marketability and introduction of new cultivars for fresh consumption of apple is the world's most important breeding objectives. in this study, the qualitative and quantitative characteristics of the genotypes from cross between red spur and golab-e-kohanz apple cultivars were evaluated. a total of 19 traits including fruit attributes (firmness, fruit weight,...) and th...

In vitro monocyte maturation was studied in patients with squamous cell carcinoma of the lung--limited to the ipsilateral hemithorax in 30 and more extensive in 40. The patients were studied prospectively and initial monocyte maturation was correlated with survival. Monocyte maturation in patients with limited disease before treatment ranged from 3.1 to 57.6% with a median value of 21.4%. The s...

While today it is universally acknowledged that COVID-19 has generated immense challenges for businesses and societies worldwide, public perceptions varied significantly at the time of pandemic’s initial appearance, even among democratic with comparable media systems. The growing scholarship on grand societal in management organization studies, however, tends to neglect social construction issu...

EGG maturation in Limnaea stagnalis has been described by Raven (1945, 1949). It exhibits some peculiarities, by which the Limnaea egg seemed to stand apart from all other animal eggs in which the maturation processes have been accurately studied so far. In the first place it appeared that the second maturation spindle arises by a direct and gradual transformation of the centrosphere at the inn...

In exploited fish stocks, long-term trends towards earlier maturation have been interpreted as an evolutionary response to sustained, high fishing mortality. The evidence used to support this diagnosis consists of directional shifts in probabilistic maturation reaction norms (PMRNs) that are consistent with the expectation that high fishing mortality favours the genotype for early maturation. M...

In general, in composting facilities the active, or intensive, stage of the process is done separately from the maturation stage, using a specific technology and time. The pre-composted material to be matured can contain enough biodegradable substrates to cause microbial proliferation, which in turn can cause temperatures to increase. Therefore, not controlling the maturation period during wast...

By MARIO BALDINI AND Ivo PANNACCIULU T HE RED BLOOD CELLS, after release from the bone marrow, continue their “maturation” in the peripheral blood. Here, the immature red cells, the reticubocytes, become mature erythrocytes. The time necessary for the reticulum substance to disappear has been defined as the “maturation time” of reticulocytes. In the past, the maturation time of reticubocytcs ha...
