Noise And Oscillations In Biological Systems: Multidisciplinary Approach Between Experimental Biology, Theoretical Modelling And Synthetic Biology
(World Scientific, 2012-08)
Rapid progress of experimental biology has provided a huge flow of quantitative data, which can be analyzed and understood only through the application of advanced techniques recently developed in theoretical sciences. On ...
Autophagy impairment: A crossroad between neurodegeneration and tauopathies
Most neurodegenerative diseases involve the accumulation of misfolded proteins in the nervous system. Impairment of protein degradation pathways such as autophagy is emerging as a consistent and transversal pathological ...
Biological evolution: ECO-EVO-DEVO in initial teachers and researchers education
(Univ Francisco Jose Caldas, Fac Science & Education, 2017-07-01)
Epistemology is an area that allows reflections about nature and construction of knowledge. In what is referred to Biological Sciences, the concept of evolution is understood as unifier axis of this science and therefore ...
Conservación in vitro de chayote (Sechium edule)
In vitro conservation of chayote (Sechium edule). The in vitro medium-term conservation technique was assayed on chayote. Survival was assayed after the addition of high concentration of sucrose (0, 30, 50, 60, 70 y 80 ...
Crioconservación de plantas, estado actual de la investigación en Costa Rica
In Costa Rica the development of cryopreservation research is recent. It started in 1990 with a project on bananas and plantains at the Agronomic Center for Research and Training (CATIE), followed by research on coffee, ...

The multitemporality of life: an analysis from Philosophy of Biology
(Universidade Estadual de Campinas. Centro de Lógica, Epistemologia e História da Ciência, 2016-07)
Although the issue of temporality has mainly been studied from Physics, this topic also exhibits diverse interesting aspects that could be addressed from a biological perspective. One possible way of approaching this subject ...
Formation of the female pronucleus and reorganization and disassembly of the first interphase cytoskeleton in the egg of the glossiphoniid leech Theromyzon rude
(Academic Press Inc., 1995)
Eggs of the leech Theromyzon rude were studied under dissecting, fluorescence, light, and electron microscopes. The sperm-derived centrosome divides and separates at early first interphase. The female pronucleus forms ...
Cell kinetics, stomatal differentiation, and diurnal rhythm in Allium cepa
Cell kinetics parameters were obtained for the three mitotic divisions leading to formation of stomata in the epidermis of the cotyledon of Allium cepa seedlings. Analysis of mitotic frequencies throughout the course of ...
