Goal /Purpose Statement
The neurodegenerative diseases include a wide range of acute and chronic conditions in which there is a loss of neurons or and glial cells in the brain and spinal cord. For example, there is a loss of dopamine neurons in Parkinson’s disease, and motor neurons in Amyotrophic Lateral Sclerosis.1 The study we will be conducted is intended to research on how gender affect transfer of mitochondrial, and or exosomes as a stem cell repair mechanism in neurodegenerative diseases.
Primarily, Many studies have reported that there is a sexual dimorphism in neurodegenerative disorders such as Parkinson’s disease, Alzheimer’s, Multiple Sclerosis, and Stroke.2 For example, female rats have greater brain tissue degeneration after

Some studies suggest that a potential origin is the primary female sex hormone, estrogen. It has neuro-protective and inflammatory-modulating effects on the brain. In ischemic brain injuries, gender related variances have been linked to this protective influence of estrogen; it was shown to improve post ischemic cerebral reperfusion and prevent dysfunction of the vascular endothelium.2, 6 However, gender differences in brain injury are exhibited even with a decline of the female sex steroid at menopause. Depending on the chromosomal content (XX or XY), there is nonconformity in some molecular mechanisms of cell survival and death. This suggests that there are hormone-independent pathways underlying the sexual dimorphism. …show more content…
It has already been discovered that there are some variances between stem cells and their activity based on the sex. Male and female stem cells vary, for example, in their neurogenic capacity, their differentiation, and cell-cycle regulation. Autologous transplantation of gender specific stem cells such as menstrual blood and Sertoli cells has been shown to, potentially, have various benefits for stroke therapy. 8 Additionally, a study has suggested that the female sex steroids, estrogen and progesterone, influence mitochondrial fusion in cortical astrocytes, thus creating gender-based discrepancies in mitochondrial function.9 So, gender may affect stem cell mitochondrial
Connell: Chapter 4 “Sex Differences & Gendered Bodies”: I found this entire chapter quite intriguing, but I really appreciate the way that Connell approaches the ways in which males and females differ, and yet she also points out how there is no significant difference in brain anatomy and function between sexes. I found the statement by neuroscientist Lesley Rogers incredibly interesting, she states, “The brain does not choose to be wither a female or a male type. In any aspect of brain function that we can measure, there is considerable overlap between females and males” (p.52). This statement when paired with information about the affect social processes have on the body is mind boggling to realize, as Connell states, “biology bends to the hurricane of social discipline” (p.55). It is unnerving to think that I am merely a product of my society.
The wide range of prospective uses for stem cells could greatly improve the health and wellbeing of many people. In stem cell treatments, undifferentiated cells are programmed to form specific cells, which can then be transplanted to the afflicted area. Stems cells can possibly treat afflictions including “Alzheimer’s diseases, spinal cord injury, stroke, burns, heart disease, diabetes, osteoarthritis, and rheumatoid arthritis” (“Stem Cell Basics”). Another important use is in drug testing. Drugs can be tested on stem cells that develop into the target tissue before using it on human test subjects, which improves safety. Finally, transplantation of organs created from stem cells could eliminate the need for human...

...ignificant evidence for my research argument indicates that the nature of gender/sex consists of a wide consensus. The latter is significant to original sex differences in brain structure and the organized role through sex differential prenatal hormone exposures through the term used in the article as (the ‘hardwiring’ paradigm). The article is limited to scientific shortcoming that presents neuroscientific research on sex and gender for it lacks an analysis that goes beyond the observed results. The article is based on neuroscience studies and how it approached gender, yet the article suggests that gender should be examined through social, culture studies, ethnicity and race. This article will not form the foundation of my research but will be used a secondary material. The neuroscience evidences will be used to support my argument and will be used as an example.
Recently mitochondrial transplants, mitochondrial donations, also referred to mitochondrial replacement has become a predominant topic in the medical community, chiefly in Canada, the United Kingdom, and the United States. Mitochondrial transplants would mean that couples who want to have a child, but the mother has defective mitochondrial deoxyribonucleic acid (mitochondrial DNA or mtDNA) could receive mitochondria from a donation. Therefore, the child would not be born with a mitochondrial disease. People who are diagnosed with mitochondrial disease have a life expectancy of nine months to fifty years, depending on when the person developed the disease. Both sides of this argument have valid opinions. Matt Ridley and Françoise Baylis wrote
Parkinson's is an idiopathic, multifactorial neurodegenerative disease that attacks neurotransmitters in the brain called dopamine. Dopamine is concentrated in a specific area of the brain called the substantia nigra. The neurotransmitter dopamine is a chemical that regulates muscle movement and emotion. Dopamine is responsible for relaying messages between the substantia nigra and other parts of the brain to control body movement. The death of these neurotransmitters affects the central nervous system. The most common symptoms are movement related, including shaking, rigidity, slowness of movement and difficulty with posture. Behavioral problems may arise as the disease progresses. Due to the loss of dopamine, Parkinson's patients will often experience depression and some compulsive behavior. In advanced stages of the disease dementia will sometimes occur. The implications of the disease on the anatomy and physiology of the respiratory and phonatory systems significantly control speech.

Alzheimer’s disease, named after Dr. Alois Alzheimer, is a disease that is on the rise in America and the rest of the world. People should learn as much as they want about this disease, because as you age, your chances of becoming an Alzheimer’s Disease, or AD, patient increases. It is estimated that approximately 3 percent of Americans between the ages of 65 and 74 have the illness, and more than half of all people over age 85 have the ailment.
Alzheimer’s disease is a complex illness that affects the brain tissue directly and undergoes gradual memory and behavioral changes which makes it difficult to diagnose. It is known to be the most common form of dementia and is irreversible. Over four million older Americans have Alzheimer’s, and that number is expected to triple in the next twenty years as more people live into their eighties and nineties. (Johnson, 1989). There is still no cure for Alzheimer’s but throughout the past few years a lot of progress has been made.
In this day and age, it seems as though almost everyone has experience a loved one taken away form a very serious disease known as Alzheimer’s disease. Alzheimer’s disease is unbelievably devastating for everyone affected by it. This disease is causing major economical problems such as less occupancy in the nursing homes, and hospitals due to the rising population of elderly men and women being diagnosed with it everyday. Because there is not yet a cure for this disease and the percent of the population being diagnosed keeps rapidly rising, more time and money needs to go towards Alzheimer’s research.
Alzheimer's Disease Introduction to Alzheimer's Alzheimer's disease is a progressive, degenerative disease of the brain. It was first described by the German neuropathologist Alois Alzheimer (1864-1915). in 1905. This disease worsens with advancing age, although there is no evidence. that it is caused by the aging process.
Although, there is proof of cognitive and mental variations in the way that two genders process information. For example, women are shown to be more adept at verbal communication and comprehension while men tend to perform better in the visual-spatial category. On the topic of memory, studies show that women are more sensory and memory oriented. In one study at the University of Edinburgh, psychologist Stuart Ritchie and a team of researchers compared data from many different male and female subjects. As Micheal Price states, “Adjusting for age, on average, they found that women tended to have significantly thicker cortices than men. Thicker cortices have been associated with higher scores on a variety of cognitive and general intelligence tests. Meanwhile, men had higher brain volumes than women in every subcortical region they looked at, including the hippocampus (which plays broad roles in memory and spatial awareness), the amygdala (emotions, memory, and decision-making), striatum (learning, inhibition, and reward-processing), and thalamus (processing and relaying sensory information to other parts of the brain).” (Price 2017). So indeed there are differences, however the similarities between genders far outweigh the differences. McGraw-Hill Higher Education argues that “More equivocal are gender differences in activity level, dependency, timidity, exploratory activity, and vulnerability to stress. There are no gender differences in sociability, conformity, achievement, self-esteem, or verbal hostility (Child Psychology).” In turn proving many once believed facts such as “women and men communicate differently, it's biology” into preconceived
It is proven that the male and female brains differ, but can one prove that it affects the behavior? Many scientists would agree that ones behavior is determined by his/her gender. Although others are convinced that social conditioning is the cause for the differences between the male and female, it is very unlikely that biological differences play no role in behavior. The male and female brains differ not only by how they work, but also on the size. For example, Natalie Angier and Kenneth Chang, neuroscientists, have shown that the women’s brain is about 10 percent smaller than the male’s, on average, even after accounting for women’s comparatively smaller body size. Three brain differences that affect ones behavior are the limbic size, the corpus collosum size, and the amount of gray and white matter.
