Background: Cryopreservation of ovaries is an important technique in assisted reproduction technology. Physical forces like hydrostatic pressure have a pivotal role in reproduction systems. Due to changes in intrafollicular pressure during ovulatory process, this study designed to examine the effects of hydrostatic pressure on oocyte maturation and cell death in cumulus cells from cryopreserved...

The microbiology of Kasseri cheese, a Protected Designation Origin (PDO) cheese pasta-filata type was studied in order to identify the dominant species and strains that may contribute maturation process. Chemical composition microbiological quality samples from two different dairies during at 0, 7, 25, 60 90 days maturation. Lactic acid bacteria Enterococcus spp. were found be microflora fresh ...

Immature neurons undergo morphological and physiological maturation in order to establish neuronal networks. During maturation, a large number of genes change their transcriptional levels, these changes may be mediated by chromatin modifiers. In this study, we found that the level Ezh1, component Polycomb repressive complex 2 (PRC2), increases during mouse neocortical culture. addition, conditi...

Mirolysin is a secretory protease of Tannerella forsythia, member the dysbiotic oral microbiota responsible for periodontitis. In this study, we show that mirolysin latency achieved by “cysteine-switch” mechanism exerted Cys23 in N-terminal profragment. Mutation shortened time needed activation zymogen from several days to 5 min. The mutation also decreased thermal stability and autoproteolysis...

In situ heat injection is a suitable technique for extracting shale oil from reservoirs with high organic matter content but insufficient thermal maturation. To optimize the stimulation process and to avoid unnecessary energy consumption, understanding effects of parameters crucial. This research employs self-developed simulator build 2D numerical model in conversion kerogen electric heaters. A...

Radiotelemetry and archival temperature loggers were used to reconstruct the thermal experience of adult spring Chinook salmon (Oncorhynchus tshawytscha) in the highly regulated Willamette River system in Oregon. The study population is threatened and recovery efforts have been hampered by episodically high prespawn mortality that is likely temperature mediated. Over three years, 310 salmon wer...
