Applied Pathology

A Guide to Applied Biology

Myra VanIsle

Greetings and welcome! I am Master Myra VanIsle, Lore Keeper Emeritus specializing in Astronomy, Archeology, Linguistics, History, and Biology. Additionally, I am a Senior Healer specializing in Pathology, Mending, and Communing. It is my pleasure to be here, and I hope to provide you with the information you seek. I will be your instructor today for Applied Biology. This class will focus on the natural process of disease and decay of living tissues, how to diagnose and treat them, and how to use preventative measures to ensure the best possible outcomes. Applied Biology studies the natural process of disease and decay of living tissues. It focuses on diagnosis and treatment, as well as the use of preventative measures to ensure the best possible outcome. Additionally, Applied Biology covers the effects that different toxins, such as those released by plants or animals, have on other species. As part of this course, students will learn how to identify and respond to common diseases and recognize the signs of potentially harmful toxins and take steps to protect themselves and others from them. Pathologists often are sent to crime scenes and sources of outbreaks to investigate the cause, examining the local environment for clues. This can help to determine the source of an outbreak or, in the case of a crime scene, to provide evidence and help identify the perpetrator. With their specialized knowledge of diseases, pathogens, and toxins, pathologists can provide invaluable insight into the cause and effect of a particular situation. Through their investigations, pathologists can help protect people from dangerous outbreaks and ensure justice is served in criminal cases.

Applied Biology

Applied Biology is the process of investigating the samples identified using Forensics which will be analyzed in this stage to identify potential causes of death, injury, or illness. Through such analysis, pathologists can determine the cause of death and any underlying conditions or toxins that could have contributed to the situation. Additionally, this process can provide valuable evidence in criminal cases that may prove helpful in solving the crime. The thorough analysis of samples collected in this stage of Applied Biology is an essential tool for pathologists and investigators alike.

Death

Today we will cover what happens to a humanoid when they die. Understanding the natural process of cellular decay and its science is essential for any healer, as it enables them to identify potential illnesses and recognize any signs of imminent death. Knowing how to recognize the signs of death can help a healer take the appropriate steps to prevent a tragedy from occurring and provide comfort for those who have suffered a loss. By understanding the natural process of death, healers can be better prepared to intervene if needed and provide a better quality of care. Death is a certainty for all living things and knowing the natural process of death can help us understand what happens when someone dies unexpectedly. By recognizing the subtle differences between natural and unnatural death, pathologists, healers, and investigators can work together to identify any signs of foul play and take action to ensure justice is served. Understanding the natural process of death also allows healers to support the bereaved family by providing them with the knowledge and comfort needed to cope with their loss. With the proper knowledge, healers can help those in need in the most challenging times. Pathologists, healers, and investigators can identify any changes that occur between natural and unnatural death by studying the natural process of death and decay. By identifying these changes, often subtle, we can hopefully learn how to prevent the subsequent death or outbreak and even bring the perpetrator to justice. To do this, we must understand how living organisms age and die and how to recognize any signs of foul play or illness before it is too late. By studying the process of death, we can ensure that everyone is given the best chance at justice and peaceful passing.

Apoptosis

Typically, humanoid cells die via apoptosis, a preprogrammed cell death that helps to keep healthy cells active. Necrosis is another cause of death and is usually due to the loss of blood flow, trauma, or disease processes. Diseases such as cancer can cause cells to die through necrosis due to the replication of cancerous cells and their subsequent destruction of healthy ones. Additionally, physical trauma to a cell can cause necrosis, resulting in the cell's immediate death before it can repair itself.

Necrosis

When cells die through necrosis, they release toxins which can spread to surrounding cells and tissues, causing further damage. This is known as inflammation and is the primary cause of injury in most wounds that healers treat. Toxic materials seep uncontrollably into the surrounding cells and tissues, causing even more damage. This can be seen in the swelling around wounds and the general reddening of the affected area.

Rigor Mortis

So, that is what happens at the cellular level after death, but it can tell us a lot about the deceased. You may have seen a dead body that is stiff and rigid, a condition known as rigor mortis. This is caused when the body's cells can no longer make energy, leading to the buildup of lactic acid, which causes stiffness in the body. Rigor mortis can provide valuable information to investigators and healers, as it can help determine the time of death and provide clues as to how the person died. By studying the body's position and comparing it to the surrounding area, investigators can determine if it has moved since its death. If the body is in a different place than it would have been when alive, it has likely been moved since the end. Examining the body's positioning can also reveal any signs of struggle or difference in positioning from when alive. This is an invaluable tool for investigators, as it can help to determine if a crime was committed and even if the deceased was moved after death. The position of a body can also be an indicator of foul play. If the position in which a body is found does not match the location where it is found, it could be an indication that someone moved the body. For example, if a body is flat on its back with one arm sticking straight up, it could be seen as a sign that someone moved it after death. This is an essential clue for investigators and pathologists alike and can help to bring resolution to a case or give insight into an outbreak.

Lividity

Another technique we can use to determine if a body has been moved after death is lividity. Lividity occurs when blood flow stops, and the body's cells become discoloured. This discoloration signifies that the body has remained in its current position since the death. This can provide critical information for investigators and pathologists, as it can confirm whether or not the body has been moved since the time of death. Ultimately, what must be taken into account is the position of the body when it is discovered. If the blood has settled, it can be determined that it has been in the same position since the death. Lividity is an essential tool when looking for signs of foul play, as it can help to discern whether the body has been moved since the death. For example, an individual lying on their stomach would be found with all the blood from their back heading toward the ground. When the body is moved after death, the lividity is disturbed, and discoloration will be seen in different areas of the body. In this way, autopsy physicians, investigators and healers alike can use lividity to determine if the body has been moved recently or not. Lividity also displays itself as a dark purple or a dark colour of the deceased's natural blood. Discoloration of the body can also be referred to as Livor Mortis and is caused by the pooling of blood in the lower parts of the body due to gravity. This discoloration of the deceased can determine if the body has been moved since the death. Additionally, healers can use lividity to identify any signs of trauma, such as bruises and scrapes, that may have occurred before or after death. Lividity can also detect any contact the deceased may have had with a firm surface. Any part of the body that has come into contact with a firm surface for some time will show signs of this during lividity. This impression against the skin displays itself as an indentation surrounded by gravity-pulled blood. This can be useful in determining whether or not the deceased had any contact with a surface before or after death, and if so, whether or not it was related to foul play or otherwise. It can also provide clues as to the cause of death, such as blunt force trauma or suffocation. While lividity can give valuable insight into the time of death and the events that led up to it, it is essential to note that it only works for the first 6 hours after death. After this time, most species' blood has thickened in the body, and the vessels have begun to break down, making it impossible for investigators to determine the time of death accurately. However, knowing this information can still be invaluable. By studying lividity and other techniques, investigators can better understand the circumstances surrounding an end and bring justice to those who can no longer speak for themselves.

Decomposition

Lastly, we can use the decomposition and degradation of cells and tissue to help determine the time of death and, in some cases, the cause. In some instances, more detailed injuries can be identified. For example, if a body is found in water, the amount of cellular degradation can help determine how long they have been submerged. Similarly, if a body has been exposed to heat and flames, the level of degradation of the skin can be used to infer how long the deceased was exposed to such conditions. As was stated earlier, all cells eventually die and break down. Most of the time, a natural order will be seen, where the skin cells will degrade first, followed by the soft tissue and then the organs. This can provide helpful information to investigators regarding the time of death, which can help to identify potential suspects or even exonerate those wrongly accused. Additionally, this degradation can help determine if any toxins were present in the body at the time of death and can be a valuable tool in identifying poisoning or other forms of foul play.

Conclusion

In conclusion, the decomposition and degradation of cells and tissue can be an invaluable tool in determining the time of death of a body and the cause. By studying the lividity and other techniques, investigators can better understand the events that occurred before and after death. This information can also be used to exonerate those wrongfully accused or identify potential suspects. All of these techniques can be used to bring justice to those who are no longer able to speak for themselves.
