The megaspore mother cell (MMC) arises from somatic cells in the ovule primordium and enters meiosis to generate four megaspores. Only the most chalazal (functional megaspore, FM) survives, undergoing a series of mitoses to form the female gametophyte. We show that this commitment to the sexual germline requires spatial regulation of ().

- * Our findings show that the critical compaction threshold needed for black hole formation closely matches the threshold for the first unstable circular orbit in a spherically symmetric setting.
- * We also discovered that the critical exponent related to primordial black hole mass near this threshold is determined by the inverse of the Lyapunov coefficient of the unstable orbits during a self-similar phase close to criticality.
The objectives of this retrospective, naturalistic study were to provide preliminary data on the effects of 6 months treatment with risperidone, olanzapine and quetiapine on behavioral disturbances, within a sample of outpatients with mild to moderate Alzheimer's disease, and on predictors of response. Between July 2005 and December 2005, data were collected from 58 consecutive outpatients with a DSM-IV-TR diagnosis of Alzheimer's disease with behavioral disturbances, who received a 6-month treatment with risperidone, olanzapine or quetiapine. Primary outcome measures were Neuropsychiatric Inventory (NPI) total score and its items forming the basic core of behavioral disturbances in Alzheimer's disease: delusions, hallucinations and agitation/aggressiveness.
