Meiosis is the cellular process responsible for producing gametes with half the genetic content of the parent cells. Integral parts of the process in most diploid organisms include the recognition, pairing, synapsis, and recombination of homolog[...]texto impreso
Differential scanning calorimetry (DSC) is a highly sensitive nonperturbing technique used for studying the thermodynamic properties of thermally induced transitions. Since these properties might be affected by ligand binding, DSC is particularl[...]texto impreso
During meiosis, accurate segregation of chromosomes requires the formation of bivalents at metaphase I. In autopolyploids, there are more than two copies of each chromosome with the same chance to form chiasmata at meiosis. This leads to the for[...]texto impreso
An improved method of preparing two-dimensional surface spreads of synaptonemal complexes (SCs) in higher plants for examination by electron microscopy is described. This protocol produces clear, well-spread preparations of SCs and unpaired axia[...]texto impreso
Crespo Castrillo, Andrea ; Yanguas Casás, Natalia ; Arévalo, María Ángeles ; Azcoitia Elías, Iñigo ; Barreto, George E. ; García Segura, Luis Miguel | Humana Press | 2018-03-26Previous studies have shown that estradiol reduces reactive gliosis after a stab wound injury in the cerebral cortex. Since the therapeutic use of estradiol is limited by its peripheral hormonal effects, it is of interest to determine whether sy[...]texto impreso
Gómez Garay, Aranzazu ; Pintos López, Beatriz ; Manzanera, José Antonio ; Lobo, Carmen ; Villalobos, Nieves ; Martín, Luisa | Humana Press | 2014-10The present study analyzes some effects of nanoCeO2 particles on the growth of in vitro plantlets of Medicago arborea when the nanoceria was added to the culture medium. Various concentrations of nano-CeO2 and bulk ceric oxide particles in suspe[...]
