Introduction Cells are building units of life and perform very important functions in our body. It takes in nutrients and convert it to energy and carry out specialized functions. Cell consists of many organelles which perform various functions. One of the main organelles is mitochondria where cellular respiration to produce energy to regulate cellular metabolism. Per Wang and D. Brinton (2016)‚ mitochondrial DNA undergoes mutation at a higher rate and its repair mechanism is very limited which

Lewy Body Dementia (LBD) is an umbrella term for two different diagnoses. It is a combination of both Parkinson’s Disease Dementia and Dementia with Lewy Bodys (1). Pathologically it is defined by the presence of alpha synuclein containing Lewy bodies in the brain‚ however their distribution differs from that in Parkinson’s Disease‚ affecting the limbic system and brainstem‚ in contrast to the nigrostriatal and brainstem predominant pattern seen in early Parkinson’s Disease (AA). Clinically‚ the

Senile Retinoschisis Senile retinoschisis is a condition that causes a person’s vision to slowly get worse (progressive). It usually affects both eyes. Retinoschisis results when the light-sensing cells at the back of the eye (retina) split from the layer of cells that send vision signals to the brain. The condition causes small fluid-filled sacs (cysts) to form in the side (peripheral) portions of the retina. The cysts can merge together and cause the layers of the retina to split. In some cases

Mitochondria is a double membrane bound organelle in charge of energy production. Mitochondria have their own DNA and manufacture their own ribosomes. They produce mitochondrial DNA and nuclear DNA. Mitochondria can be considered a dynamic organelle because their core function is ATP production. Mitochondria produce about ninety percent of the body’s energy. They migrate within the cells and continuously divide and fuse with each other (Santos‚ 2010). They are responsible for producing energy to
