During skeletal muscle development, nuclei move toward the center of the myotube after myoblast fusion and spread along the center of the myotube prior to positioning at the periphery of the myofiber (Cadot et al, 2012; Metzger et al, 2012).
Our results show that MIRO1 and MIRO2 are unequally redundant in function and that both genes affect pollen tube growth, fusion of polar nuclei during embryo sac development and possibly also nuclei fusion during fertilization.
The closest modern analogue is the South Saskatchewan River, in which large simple flow-transverse bedforms become exposed and dissected during falling stage, and act as nuclei for sand-flat development.
The survival, growth and development rates, erythrocytes nuclei aberrations, parasite infection, and brain cholinesterase activity were monitored after seven days of exposure.
Centrally located nuclei indicative of ongoing muscle development were detected in both dystrophic and control mouse muscle, whereas in the dystrophic muscle an inflammatory infiltrate in the area positive for calcium uptake was observed as well.
These new findings provide insight into the signaling mechanisms behind loss of nuclei and organelles during the development of the lens, with implications for other developmental mechanisms in which autophagic processes are necessary for tissue maturation.
The mechanical behavior of materials can be modeled and evaluated across multiple scales that encompass: atomic and molecular rearrangements to create incipient defect nuclei; combination or growth of such nuclei to form micro-scale and subsequently macro-scale defects; and finally development of critical flaw sizes that result in final failure of engineering structures.
"Almost always it provides employment opportunities for people in those communities and acts as nuclei for economic growth".
Aberrant nuclei refer to nuclei with abnormal morphology, such as fragmented nuclei or nuclei with irregular shapes.
At ultrastructural level, changes in distribution of condensed chromatin and nucleolus compactization in nuclei, noticeable accumulation of lipid bodies, development of a lytic compartment (vacuoles, cytosegresomes and paramural bodies), and reduction of phytoferritin in plastids in meristem cells were observed in pea roots exposed to weak magnetic field.
