The Development of Lock Hospitals Within England for Female Sex Workers During the 19th Century

Leave a comment

Due to the fact that sexually transmitted infections and diseases were rampant among English soldiers, in 1864 novel legislation entitled the Contagious Diseases Act was passed which permitted any woman suspected of prostitution as young as 13 years of age, to be forcibly examined by a physician. Institutions referred to as “lock hospitals” were established and setup so that women suspected of spreading disease could be detained and examined, and if they were positive in their evaluation, they could then be incarcerated for up to 3 months. It never occurred however to the English government that men could also spread sexually transmitted infections and diseases which is why men were immune from this legislation and a key reason as to why the problem was never resolved. Because of this, in 1886, this legislation was repealed

The Correlation Between Cats and the Bubonic Plague of Europe

Leave a comment

During the Middle Ages and up until the Salem Witch Trials, cats were killed alongside their owners who were believed to be practicing the dark arts of magic, sorcery, and witchcraft. Typically cats were burned alive in ceremonial bonfires. Ironically, had this not occurred, the Bubonic Plague probably wouldn’t have been as prolific as it was as the fleas found upon the rats who carried the disease, would have been killed alongside their host by the very cats which were killed in droves by human beings. Cats are partially resistant to the Bubonic Plague but with few to keep the rat population in check, the plague was able to wash over Europe and kill 25,000,000 (25 million) people which was 25% of the European population

The Argument Against Private Corporation Umbilical Cord Blood Storage

Leave a comment

Canadian Blood and Tissue Bank Insception Life Blood claims that 80 life threatening diseases (e.g. various cancers, metabolic diseases, immune diseases etc.) can be treated with umbilical cord blood, and that these diseases have been treated with success for over 2 decades, with over 45,000 pediatric transfusions worldwide. The majority of these transfusions however were accomplished due to public cord blood banks. Physicians can tap into worldwide public registries with nearly 1,000,000 (1 million) donors to find a match for a patient and this service is free. In the setting of leukemia or a genetic defect, physicians would want to use cord blood which is not biologically related to the patient to avoid having the problem continue. The American Academy of Pediatrics states, “private storage of cord blood as biological insurance should be discouraged”. There is a caveat to this however, in the case of a child having a genetic defect, it is recommended that the family save the cord blood of the next child, if another child is born. It is believed that private cord blood corporations leverage fear, uncertainty, and timed pressure to cajole families into deciding to privately store cord blood. Insception Life Blood has stored cord blood from 70,000 infants yet only 14 were released for transplant, a value of 1 in 5000

The Accidental Discovery of Tea and the Agricultural Advents Developed by Chinese Emperor Jiang Shinian

Leave a comment

Tea was discovered entirely by accident. The first emperor of ancient China, Emperor Jiang Shinian (Shen Nung or Shennong) was boiling water in his palace courtyard when a tea leaf fell from above, and into the boiling pot. Due to the pleasant scent, Jiang ingested the water as it cooled and by coincidence discovered the activity of tea consumption. The name Jiang Shinian directly translates to mean “Devine Husbandman” within Mandarin, as it is believed Jiang developed multiple Chinese agricultural advents (e.g. crop cultivation for medicinal herbs, soil managment strategies, irrigation etc.). It should be noted, this account of the discovery of tea is believed to most likely be fictitious and mythological in origin by Chinese historians during the modern day

How the Rabies Virus Pathogen Infects and Propagates Within Mammalian Hosts

Leave a comment

The rabies virus causes hostility within its host because aggressive behavior (e.g. biting etc.) is crucial for the transmission of the pathogen due to the fact that the virus is primarily secreted within the saliva of its hosts, although it can be present within and therefore transmitted via other tissues as well (e.g. infected brain tissue coming into contact with the open wound of a host etc.). The rabies virus primarily affects the central nervous system of its host, involving both the brain and spinal cord, causing inflammation of the brain referred to as “encephalitis”, and triggering various other neurological symptoms which help aide propogation (e.g. aggression, confusion, hallucinations etc.). The rabies virus travels along nerves from the wound site of the infection to the brain, where it then replicates and causes inflammation. Once the rabies virus reaches the brain, it can spread rapidly throughout the body via the central nervous system, leading to severe neurological symptoms and death in 100% of cases if left untreated

The Importance of Gastrointestinal Microbes for Weight Loss

1 Comment

There are 100,000,000,000,000 (100 trillion) microbes within the gastrointestinal system and scientists have learned that by transplanting microbes from one animal to another, weight gain and weight loss can be turned on and off at will. Scientists now understand that the greater diversity a person has in terms of the types of microbial life which live within their body, the less likely they are to gain weight or maintain a higher than ideal body weight, with the exact opposite effect occurring in those who have lower than average values in reference to the number of microbes living within the body. Diets rich in fiber are typically associated with higher values of microbes, so increasing fiber intake, can significantly reduce overall body weight and promote the existence and health of many different kinds of microbes. Increasing fiber content for only a few days, has a measurable and marked effect upon microbrial gastrointestinal health

How Breath Alcohol Analysis Works

1 Comment

Alcohol shows up in the breath because it gets absorbed from the mouth, throat, stomach and intestines into the bloodstream. Alcohol­ is not digested upon absorption, nor chemically changed in the bloodstream. As blood circulates through the lungs, some of the alcohol moves across the membranes of the lung’s alveoli, into the air stored within the lungs. Because the alcohol concentration in the breath is related to the concentration in the blood, an approximate measurement can be identified when using a simple ratio formula of breath alcohol to blood alcohol which is 2100:1. This means that 2100 milliliters of alveolar air will contain the same amount of alcohol as 1 milliliter of blood

The Country With the Most Vegetarians Per Capita and the First Notation of Vegetarianism Within Western Literature

1 Comment

The country with the most vegetarians per capita is India, with 39% of the country identifying as vegetarian and/or vegan, a value which equates to 276,000,000 (276 million) people. This is primarily due to the dominant religion within India which is Hinduism, a faith which 79.8% of the country subscribes to, and to a lesser extent, Sikhism, a faith which promotes vegetarianism and is subscribed to by 1.7% of the country. Mexico trails India for the second spot internationally with 19% of the country identifying as vegetarian and Brazil takes the third spot with 14% having adopted this diet. The first time vegetarianism is mentioned within recorded western history is by the Ancient Greek mathematician Pythagoras around 500 BC, however it is unclear if this is the first recorded text worldwide

The Origin of the Use of Analgesia While Giving Birth

1 Comment

Analgesia was not an option while giving birth until the mid 19th century as pain was believed to be a crucial part of the birthing experience. In 1591, Euphemia Maclean, a woman from Edinburgh, Scotland requested analgesia during the birth of her twins and was burned at the stake for this request. Analgesia started with Queen Victoria who used chloroform for the birth of her 8th child Leopold. It was Victoria’s experience that she told to others which made the practice catch on so quickly as Victoria felt that analgesia was an amazing invention which helped her immensely. In the 1950’s, the no medication approach swung back into fashion with Dr. Grantly Dick-Read, the first modern physician to suggest against analgesia as he believed the pain of childbirth to be psychological

The Discovery of Bacterium Causing Stomach Ulcers

Leave a comment

For decades the medical community believed gastric ulcers were directly related to stress with the only options for relief being antacids and surgery. In the early 1980’s, Australian physicians Barry Marshall and Robin Warren discovered through biopsies of gastric ulcers, that nearly all were overrun by helicobacter pylori bacteria. Helicobacter pylori only seems to infect humans, as studies performed upon pigs and rats were unsuccessful as these animals were unable to contract the bacterium. Marshall decided to infect himself and within 5 days of doing so, he started running to the bathroom each morning to throw up. Tests demonstrated that Marshall had gastritis, a precursor to an ulcer. Marshall took antibiotics and was cured, proving once and for all that ulcers are caused by bacteria not stress. In 2005, Marshall and Warren won the Nobel Prize in Medicine for their findings
