Neuronal growth cone advance was investigated by correlative light and electron microscopy carried out on chick dorsal root ganglion cells. Advance was analyzed in terms of the two principal organelles responsible for protrusive motility in the growth cone - namely, veils and filopodia. Veils alternated between rapid phases of protrusion and retraction. Electron microscopy revealed characterist...

 ABSTRACT
 This paper explores a way to ensure person’s autonomy and legacy are preserved during the experience of dementia due Alzheimer’s disease. Due profound effect disease has memory, “person lifetime” (the past experiences their future aspirations prior progression) becomes seemingly disconnected from moment,” or person experiencing memory lo...

Objective High concentration of iron and other trace elements could restrict bacterial growth and modify their metabolic pattern as well. However, this study aimed to find out the influence of iron, chromium, cadmium and synergism or antagonism between these elements on the growth of a gram positive bacterium. Materials and Methods In a series of experiments, Bucillus cereus was cultured in a n...

Models are presented for predicting: (1) height growth of red oak advance reproduction after dearcutting, and (2) the probability of stems becoming dominants or codominants in new stands as a function of preharvest size of advance reproduction and site quality. The second model permits silviculturists o predict, prior to harvest, the contribution to a new stand of an existing population of adva...

Growth cones of cortical axons pause for many hours in preparation for axon branching. They become large and complex compared with small advancing growth cones. We wanted to investigate whether calcium transients regulate the advance of mammalian CNS growth cones. We found that spontaneous calcium transients in developing cortical neurons have characteristic patterns, frequencies, and amplitude...

One of the main challenges faced in design and construction phases of tunneling projects is the determination of maximum allowable advance step to maximize excavation rate and reduce project delivery time. Considering the complexity of determining this factor and unexpected risks associated with inappropriate determination of that, it is necessary to employ a method which is capable of accounti...
