Comparison of CellRox green fluorescence upon thawing on and embryos cryopreserved by slow freezing or vitrification.

The aim of this study was to compare the levels of reactive oxygen species (ROS) in and embryos cryopreserved using either slow freezing or vitrification. Embryos were divided into four groups based on subspecies and freezing method: slow freezing (BiSF; = 8), vitrification (BiVT; = 10), slow freezing (BtSF; = 9), and vitrification (BtVT; = 6). After thawing, the embryos were incubated with CellRox Green and images were obtained using a confocal microscope.

Association between Intracellular Calcium Signaling and Tumor Recurrence in Human Non-Functioning Pituitary Adenomas.

Clinically non-functioning pituitary adenomas (CNFPAs) are the second most frequent sellar tumor among studies on community-dwelling adults. They are characterized by the absence of hormonal hypersecretion syndrome, and patients present with compressive symptoms, such as a headache and visual field defects. Immunohistochemically, most CNFPAs are of gonadotrope differentiation, with only a few of them being truly null cell adenomas.

Altered functional connectivity and network excitability in a model of cortical dysplasia.

Focal cortical dysplasias (FCDs) are malformations of cortical development that often result in medically refractory epilepsy, with a greater incidence in the pediatric population. The relationship between the disturbed cortical morphology and epileptogenic activity of FCDs remains unclear. We used the BCNU (carmustine 1-3-bis-chloroethyl-nitrosourea) animal model of cortical dysplasia to evaluate neuronal and laminar alterations and how these result in altered activity of intracortical networks in early life.
