A young black scientist discovered a key treatment for leprosy in the Nineteen Twenties, but his older colleague took credit

Published

Hansen’s disease, also called leprosy, is curable today – thanks in part to the interesting tree and the pioneering work of a young scientist in the Nineteen Twenties. Centuries before its discovery, there was no cure for the debilitating symptoms of leprosy and its social stigma.

This young scientist Alicja Bal, laid the foundations for the world’s first effective treatment for leprosy. However, her legacy continues to prompt conversations about the marginalization of girls and folks of color in science today.

How bioethicist and historian of medicationI even have examine Ball’s contributions to medicine and I’m pleased to see that she is increasingly recognized for her work, especially in a disease that is still stigmatized.

Who was Alice Ball?

Alice Augusta Ball, born in Seattle, Washington in 1892, was first woman and first African American to acquire a master’s degree in science from the College of Hawaii in 1915, after graduating in pharmaceutical chemistry the previous yr.

Alice Augusta Ball, who invented the Ball Method, a approach to treating leprosy that didn’t involve unmanageable uncomfortable side effects.

After completing her master’s degree, the university hired her as a chemist and instructor, making her the first African American woman to carry this degree in the chemistry department.

Impressed with his master’s thesis in chemistry kava plantBall was recruited by Dr. Harry Hollmann of the U.S. Public Health Service leprosy investigation station in Hawaii. Then, leprosy was a major public health problem in Hawaii.

Doctors now understand that leprosy, also called Hansen’s disease, is minimally contagious. However, in 1865, the fear and stigma related to leprosy led Hawaiian authorities to implement a policy of mandatory segregation that ultimately isolated individuals with the disease. a distant peninsula on the island of Molokai. In 1910 There were over 600 individuals with leprosy in Molokai.

These policies overwhelmingly affected the Native Hawaiians who constituted over 90% of all those exiled to Molokai.

Meaning of chaulmoogra oil

Doctors tried almost every possible treatment to treat leprosy, even experimenting with dangerous substances equivalent to arsenic and strychnine. But the only consistently effective treatment was chaulmoogra oil.

Chaulmoogra oil is obtained from seeds chaulmoogra tree. Healthcare employees in India and Burma has used this oil for centuries as a medicine for various skin diseases. However, the treatment had limitations and had only a marginal effect on leprosy.

The oil could be very thick and viscous, making it difficult to rub into the skin. The drug can also be very bitter and patients who consumed it often began to vomit. Some doctors have experimented with oil injections, but this they produced painful pimples.

Ball method

If scientists could harness the healing potential of chaulmoogra without the unpleasant uncomfortable side effects, the tree’s seeds could revolutionize the treatment of leprosy. So Hollmann turned to Ball. In an article from 1922Hollmann documents how the 23-year-old Ball discovered the best way to chemically adapt chaulmoogra into an injection that caused no uncomfortable side effects.

The Ball method, as Hollmann called her discovery, transformed chaulmoogra oil into the simplest cure for leprosy until introduction of sulfones in the late Nineteen Forties.

In 1920, 78 patients in Honolulu were cured using the Ball Method. A yr later, 94 more were treated The Public Health Service took note of this the morale of all patients improved dramatically. For the first time there was hope for a cure.

Tragedy, Ball he did not have a likelihood to brag over this achievementas she died inside a yr at the age of only 24, possibly from exposure chlorine gas in the lab.

Ball’s legacy, lost and located

Ball’s death meant she had no opportunity to publish her research. Arthur Dean, chairman of the College of Hawaii’s chemistry department, took over the project.

Dean mass-produced the treatment and published a series of articles on chaulmoogra oil. He modified the name of the Ball method to the “Dean Method” i he never credited Ball for her work.

Ball’s other colleagues did try to guard Ball’s legacy. A 1920 article in the Journal of the American Medical Association praises Ball’s method, while Hollmann explicitly credits Ball in his 1922 article.

The ball is described in detail in Article from 1922 in volume 15, issue 5, Current History, an educational publication on international affairs. This feature is taken from: a June 1941 issue “Negro History Bulletin” by Carter G. Woodson, referring to Ball’s achievements and premature death.

Joseph Duttona respected religious volunteer in the leper settlements of Molokai, he further referred to Ball’s work in Widely published memoirs from 1932 for a popular audience.

Historians like Paweł Wermager it later led to a modern reckoning with Ball’s mistreatment by Dean and others, ensuring that Ball received proper recognition for her work. Following the work of Wermager et al., University of Hawaii honored the Ball in 2000 with a bronze badgeattached to the last remaining chaulmoogra tree on campus.

In 2019, the London School of Hygiene and Tropical Medicine added Ball’s name outside his constructing. Ball’s story was even featured in a 2020 short film, “Ball method

Ball’s method represents each a scientific achievement and a history of marginalization. The young woman of color pioneered the treatment of a highly stigmatizing disease that disproportionately affected already disenfranchised indigenous people.

The state of Hawaii honored Ball by proclaiming February 28 as Alice Augusta Ball Day.

In 2022, then-Gov. David Ige declared February twenty eighth as Alice Augusta Prom Day in Hawaii. It was the only thing that fit Ceremony took place on the Mānoa campus in the shade of the chaulmoogra tree.

The family of Tire Sampson, the 14-yr-old who tragically died on an amusement park ride in Orlando, Florida, in 2022, has been awarded $310 million in a civil lawsuit.

Tire, who was visiting ICON Park along with his family on March 24, 2022, fell from the FreeFall drop tower. Although he was taken to a nearby hospital, he didn’t survive his injuries.

Now, greater than two years later, a jury has held the vehicle manufacturer, Austria-based Funtime Handels, responsible for the accident and awarded the Tire family $310 million. According to reports from local news stations WFTV AND KSDKthe jury reached its verdict after about an hour of deliberation.

Tyre’s parents will each receive $155 million, according to attorney spokesman Michael Haggard.

Attorneys Ben Crump and Natalie Jackson, who represented Tyre’s family, shared their thoughts on this landmark decision via X (formerly Twitter). “This ruling is a step forward in holding corporations accountable for the safety of their products,” they said in a statement.

Lawyers stressed that Tyre’s death was attributable to “gross negligence and a failure to put safety before profits.” They added that the ride’s manufacturer had “neglected its duty to protect passengers” and that the substantial award ensured it could “face the consequences of its decisions.”

Crump and Jackson said they hope the result will encourage change throughout the theme park industry. “We hope this will spur the entire industry to enforce more stringent safety measures,” they said. “Tire heritage will provide a safer future for drivers around the world.”

An investigation previously found that Tyre’s harness was locked through the descent, but he dislodged from his seat through the 430-foot fall when the magnets engaged. Tire’s death was ruled the result of “multiple injuries and trauma.”

ICON Park said at the time that it could “fully cooperate” with the authorities.

Tireless HIV/AIDS advocate A. Cornelius Baker dies

Published

By

HIV/AIDS Advocate, A. Cornelius Baker


A. Cornelius Baker, a tireless advocate of HIV and AIDS testing, research and vaccination, died Nov. 8 at his home in Washington, D.C., of hypertensive, atherosclerotic heart problems, in response to his partner, Gregory Nevins.

As previously reported, Baker was an early supporter for people living with HIV and AIDS within the Nineteen Eighties, when misinformation and fear-mongering in regards to the disease were rampant.

According to Douglas M. Brooks, director of the Office of National AIDS Policy under President Obama, it was Baker’s Christian faith that guided him toward compassion for others.

“He was very kind, very warm and inclusive – his circles, both professional and personal, were the most diverse I have ever seen, and he was guided by his Christian values,” Brooks told the outlet. “His ferocity was on display when people were marginalized, rejected or forgotten.”

In 1995, when he was executive director of the National AIDS Association, Baker pushed for June 27 to be designated National HIV Testing Day.

In 2012, he later wrote on the web site of the Global Health Advisor for which he was a technical advisor that: “These efforts were intended to help reduce the stigma associated with HIV testing and normalize it as part of regular screening.”

Baker also feared that men like himself, black gay men, and other men from marginalized communities were disproportionately affected by HIV and AIDS.

Baker pressured the Clinton administration to incorporate black and Latino people in clinical drug trials, and in 1994 he pointedly told the Clinton administration that he was bored with hearing guarantees but seeing no motion.

According to Lambda Legal CEO Kevin Jennings, yes that daring attitude that defines Baker’s legacy in the world of ​​HIV/AIDS promotion.

“Cornelius was a legendary leader in the fight for equality for LGBTQ+ people and all people living with HIV,” Jennings said in a press release. “In the more than twenty years that I knew him, I was continually impressed not only by how effective he was as a leader, but also by how he managed to strike the balance between being fierce and kind at the same time. His loss is devastating.”

Jennings continued: “Cornelius’ leadership can’t be overstated. For many years, he was one in all the nation’s leading HIV/AIDS warriors, working locally, nationally and internationally. No matter where he went, he proudly supported the HIV/AIDS community from the Nineteen Eighties until his death, serving in various positions including the Department of Health and Human Services, the National Association of Persons with Disabilities AIDS, and the Whitman-Walker Clinic . Jennings explained.

Jennings concluded: “His career also included several honors, including being the first recipient of the American Foundation for AIDS Research Foundation’s organization-building Courage Award. Our communities have lost a pillar in Cornelius, and as we mourn his death, we will be forever grateful for his decades of service to the community.”

Kaye Hayes, deputy assistant secretary for communicable diseases and director of the Office of Infectious Diseases and HIV/AIDS Policy, in her comment about his legacy, she called Baker “the North Star.”.

“It is difficult to overstate the impact his loss had on public health, the HIV/AIDS community or the place he held in my heart personally,” Hayes told Hiv.gov. “He was pushing us, charging us, pulling us, pushing us. With his unwavering commitment to the HIV movement, he represented the north star, constructing coalitions across sectors and dealing with leaders across the political spectrum to deal with health disparities and advocate for access to HIV treatment and look after all. He said, “The work isn’t done, the charge is still there, move on – you know what you have to do.” It’s in my ear and in my heart in the case of this job.

Hayes added: “His death is a significant loss to the public health community and to the many others who benefited from Cornelius’ vigilance. His legacy will continue to inspire and motivate us all.”

Baker is survived by his mother, Shirley Baker; his partner Nevins, who can be senior counsel at Lambda Legal; his sisters Chandrika Baker, Nadine Wallace and Yavodka Bishop; in addition to his two brothers, Kareem and Roosevelt Dowdell; along with the larger HIV/AIDS advocacy community.

Bovaer is added to cow feed to reduce methane emissions. Does it pass into milk and meat? And is it harmful to humans?

Published

on

By

There are growing concerns in regards to the use of feed supplements, Bowar 10to reduce methane production in cows.

Bovaer 10 consists of silicon dioxide (mainly sand), propylene glycol (food stabilizer approved by Food Safety Australia New Zealand) and lively substance 3-nitrooxypropanol (3-NOP).

There has been an enormous amount of misinformation in regards to the safety of 3-NOP, with some milk from herds fed this additive being labeled “Frankenmilk”. Others feared it could get to humans through beef.

The most significant thing is that 3-NOP is secure. Let’s clear up some major misconceptions.

Why do we want to limit methane production?

In our attempts to limit global warming, we’ve placed the best emphasis on CO₂ because the major man-made greenhouse gas. But methane is also a greenhouse gas, and although we produce less of it, it is: a much stronger greenhouse gas than CO₂.

Agriculture is the largest a man-made source of methane. As cattle herds expand to meet our growing demand for meat and milk, reducing methane production from cows is a vital way to reduce greenhouse gas emissions.

There are several ways to do that. Stopping bacteria within the stomachs of cows that produce methane one approach is to produce methane.

The methane produced by cows and sheep doesn’t come from the animals themselves, but from the microbes living of their digestive systems. 3-NO stop the enzymes that perform the last step of methane synthesis in these microorganisms.

3-NOP is not the one compound tested as a feed additive. Australian product based on seaweed, Rumin8for instance, it is also in development. Saponins, soap-like chemicals present in plants, and essential oils as well has been examined.

However, 3-NOP is currently one of the popular effective treatments.

But is not it poison?

There are concerns on social media that Bovaer is “poisoning our food.”

But, as we are saying in toxicology, it’s the dose that makes the poison. For example, arsenic is deadly 2–20 milligrams per kilogram of body weight.

In contrast, 3-NOP was not lethal on the doses utilized in safety studies, up to 600 mg 3-NOP per kg body weight. At a dose of 100 mg per kg body weight in rats, it didn’t cause any adversarial effects.

What about reproductive issues?

The effect of 3-NOP on the reproductive organs has generated numerous commentary.

Studies in rats and cows showed that doses of 300–500 mg per kg body weight caused: contraction of the ovaries and testicles.

In comparison, to achieve the identical exposure in humans, a 70 kg human would want to eat 21–35 grams (about 2 tablespoons) of pure 3-NOP every day for a lot of weeks to see this effect.

No human will likely be exposed to this amount because 3-NOP doesn’t pass into milk – is fully metabolized within the cow’s intestines.

No cow will likely be exposed to these levels either.

What about cancer?

3-NOP is not genotoxic or mutagenicwhich implies it cannot damage DNA. Thus, the results of 3-NOP are dose-limited, meaning that small doses will not be harmful, while very high doses are (unlike radiation where there is no secure dose).

Scientists found that at a dose of 300 mg per kilogram of body weight benign tumors of the small intestine of female ratsbut not male rats, after 2 years of every day consumption. At a dose of 100 mg 3-NOP per kg body weight, no tumors were observed.

Cows eat lower than 2 grams of Bovaer 10 per day (of which only 10% or 0.2 grams is 3-NOP). This is about 1,000 times lower than the appropriate every day intake 1 mg 3-NOP per kg body weight per day for a cow weighing 450 kg.

This level of consumption will likely be not the result in cancer or any of them other adversarial effects.

So how much are people exposed to?

Milk and meat consumers will likely be exposed to zero 3-NOP. 3-NOP doesn’t penetrate milk and meat: is completely metabolized within the cow’s intestines.

Farmers could also be exposed to small amounts of the feed additive, and industrial employees producing 3-NOP will potentially be exposed to larger amounts. Farmers and industrial employees already wear personal protective equipment to reduce exposure to other agricultural chemicals – and it is advisable to do that with Bovear 10 as well.

How widely has it been tested?

3-NOP has been in development for 15 years and has been subject to multiple reviews by European Food Safety Authority, UK Food Safety Authority AND others.

It has been extensively tested over months of exposure to cattle and has produced no unintended effects. Some studies actually say so improves the standard of milk and meat.

Bovaer was approved for use in dairy cattle by the European Union from 2022 and Japan in 2024. It is also utilized in many other countries, including: in beef products, amongst others Australia.

A really small amount of 3-NOP enters the environment (lower than 0.2% of the dose taken), no accumulates and is easily decomposed subsequently, it doesn’t pose a threat to the environment.

Since humans will not be exposed to 3-NOP through milk and meat, long-term exposure is not an issue.

What does Bill Gates have to do with this?

Bill Gates has invested in a distinct feed processing method for methane, Australian seaweed-based Rumin8. But he has nothing to do with Bovaer 10.

The Bill & Melinda Gates Foundation awarded research grants to the corporate producing 3-NOP for malaria control researchnot for 3-NOP.

The bottom line is that adding 3-NOP to animal feed doesn’t pose any risk to consumers, animals or the environment.
