Pollen tubes are an excellent model for the understanding of plant cell behavior. [19] They are easily cultivated in vitro and have a very dynamic cytoskeleton that polymerizes at very high rates, providing the pollen tube with interesting mechanical properties. [20] The pollen tube has an unusual kind of growth; it extends exclusively at its apex.
If the pollen is compatible it will germinate and begin to grow. [5] The ovary releases chemicals that stimulates a positive chemotropic response from the developing pollen tube. [6] In response the tube develops a defined tip growth area that promotes directional growth and elongation of the pollen tube due to a calcium gradient. [5]
The biochemistry of Alzheimer's disease, the most common cause of dementia, is not yet very well understood. Alzheimer's disease (AD) has been identified as a proteopathy: a protein misfolding disease due to the accumulation of abnormally folded amyloid beta (Aβ) protein in the brain. [1]
The pollen is carried to the pistil of another flower, by wind or animal pollinators, and deposited on the stigma. As the pollen grain germinates, the tube cell produces the pollen tube, which elongates and extends down the long style of the carpel and into the ovary, where its sperm cells are released in the megagametophyte.
The prevention of dementia involves reducing the number of risk factors for the development of dementia, and is a global health priority needing a global response. [1] [2] Initiatives include the establishment of the International Research Network on Dementia Prevention (IRNDP) [3] which aims to link researchers in this field globally, and the establishment of the Global Dementia Observatory ...
Alois Alzheimer is often credited with first linking plaques to dementia in a 1906 presentation (published in 1907), [12] but this short report focused mainly on neurofibrillary tangles, and plaques were only briefly mentioned. [4] Alzheimer's first substantive description of plaques appeared in 1911. [11]
Lithium treatment has been shown to reduce the density of neurofibrillary tangles in transgenic models in the hippocampus and spinal cord. Despite the decrease in density of NFTs, motor and memory deficits were not seen to improve following treatment. Additionally, no preventive effects have been seen in patients undergoing lithium treatment. [22]
Frontotemporal dementia (FTD) is an early onset disorder that mostly occurs between the ages of 45 and 65, [13] but can begin earlier, and in 20–25% of cases onset is later. [11] [14] Men and women appear to be equally affected. [15] It is the most common early presenting dementia. [16]
