Towana Looney, who had been on dialysis for eight years, became the fifth American to receive a gene-edited pig kidney transplant at New York University Hospital. The transplant was a success, with the kidney immediately turning a healthy color and functioning properly. This groundbreaking procedure is expected to become a lifesaving technology for many patients suffering from organ failure.
Groundbreaking Gene-Edited Pig Kidney Transplant Offers Hope to Organ Failure Patients
Background:
The search for effective and life-sustaining organ transplants has led to groundbreaking advancements in medical science. In recent years, the use of animal organs has emerged as a promising solution to the shortage of human donor organs. However, compatibility issues between human and animal organs have hindered the widespread adoption of such transplants.
Gene-Edited Pig Kidneys:
Gene editing techniques, particularly CRISPR-Cas9, have made it possible to modify animal organs to reduce compatibility issues. Scientists have successfully edited pig genes that code for molecules that trigger immune rejection in humans. These gene-edited pigs can now provide organs that are more closely compatible with human recipients.
Towana Looney's Transplant:
In October 2022, Towana Looney, an 62-year-old woman with end-stage kidney disease, made history as the fifth American to receive a gene-edited pig kidney transplant. The transplant was performed at New York University Hospital by a team led by Dr. Robert Montgomery.
The transplant was a success, with the pig kidney immediately turning a healthy color and functioning properly. Ms. Looney's condition has remained stable since the procedure, and she has shown no signs of rejection.
Significance:
The successful transplant is a major milestone in the field of organ transplantation. It demonstrates the potential of gene-edited animal organs to overcome the shortage of human donors and provide a life-saving solution for patients suffering from organ failure.
Top 5 FAQs and Answers:
1. How does gene editing make pig kidneys compatible with humans?
Gene editing techniques remove or modify specific genes in pigs that code for molecules that trigger immune rejection in humans. This allows the pig kidneys to be more closely compatible with human recipients.
2. What are the advantages of gene-edited pig kidneys over human donor kidneys?
Gene-edited pig kidneys have the potential to provide a readily available supply of organs, reducing the waiting time for patients in need. They also have the potential to improve compatibility, reducing the risk of rejection and the need for immunosuppressive drugs.
3. How long will it be before gene-edited pig kidneys are widely available for transplantation?
The timeline for widespread availability of gene-edited pig kidneys depends on the results of ongoing clinical trials and regulatory approval processes. It is anticipated that it will take several years before the procedure becomes routine.
4. What are the concerns about gene-edited pig kidneys?
There are concerns about the potential for long-term rejection, the transmission of animal viruses to humans, and the ethical implications of using animal organs in humans.
5. What are the next steps in research on gene-edited pig kidneys?
Ongoing research is focused on improving the compatibility of pig kidneys by further modifying pig genes, monitoring the long-term outcomes of recipients, and addressing ethical concerns. Scientists are also exploring the use of gene-edited organs from other animals, such as pigs and cows.
Indian-American astronaut Sunita Williams and her colleague Barry Wilmore have been stuck at the International Space Station for six months due to a malfunctioning spacecraft. Their rescue mission has been further delayed as NASA announced a delay in the return flight on SpaceX's Crew-9 Dragon capsule. They are now expected to spend close to ten months in space, raising concerns about their health as astronauts require twice as many calories in space due to changes in their metabolism. NASA's Commercial Crew Programme Manager has commended the SpaceX team for their efforts in preparing a new spacecraft for the mission.
Russian scientists have developed a vaccine that may be able to treat cancer, offering hope to patients who previously had no guaranteed cure. The vaccine is currently in testing and is expected to be available in early 2025. While there is still more testing to be done, pre-clinical trials have shown promising results in slowing the growth and spread of cancer. It will be available for free in Russia, but there is no information yet on which types of cancer it will treat or what the name of the vaccine will be. Similar treatments are also being developed in other countries, such as the UK.
With the Gaganyaan mission quickly approaching, the Indian Space Research Organisation (Isro) has made significant progress in its preparations. All propulsion systems for the launch vehicle are ready, the crew escape system has been tested, and the crew and service modules are in the process of integration. According to the reply by Minister of State for Space Dr Jitendra Singh, the first uncrewed mission is targeted for the end of 2024, with a series of further missions set for 2025 and 2026. With all the ground infrastructure and support systems in place, India is gearing up for a historic first crewed mission in 2026.
Mid-December marks the peak of the annual Geminid meteor shower, where the skies come alive with bright and abundant shooting stars. Unlike most meteor showers, the Geminids are caused by debris from an asteroid, and can appear in multiple colors like white, yellow, green, red, and blue. You won't need any special equipment to witness this spectacular event, so mark your calendars for December 13-14 to catch a glimpse of the dazzling Geminids.
The US Department of Agriculture has announced new measures to monitor the spread of bird flu among dairy cows, following concerns over its impact on poultry and dairy herds. With over 400 dairy herds affected, the virus was found in cows earlier this year, sparking concerns of its spread through the milk supply. The USDA's decision includes testing lactating cows and restricting their interstate movement, as well as ongoing measures to ensure the safety of pasteurized milk for human consumption.
According to a recent study by scientists at the University of South Florida and Tampa General Hospital Cancer Institute, the high consumption of ultra-processed foods, such as potato chips and ready-made meals, may be causing chronic inflammation, suppressing the immune system and fueling the growth of colon cancer tumors. The study found a significantly higher number of lipids in these tumors, which are produced by the breakdown of processed foods and promote inflammation. The research also suggests that incorporating omega-3 fatty acids from natural sources, such as avocados and olive oil, may offer new potential for treatments to combat colon cancer. However, the transition away from processed foods will not be an easy one as they are often laden with unhealthy ingredients like sugar, saturated fats and seed oils.
The 10th World Ayurveda Congress and AROGYA Expo, attended by delegates from 54 countries, highlighted the potential of Ayurveda to revolutionize global healthcare systems. Prime Minister Narendra Modi called for a new blueprint to promote Ayurveda globally, while Uttarakhand Chief Minister Pushkar Singh Dhami praised the event's role in combining Ayurveda and Yoga. Union Minister of State for AYUSH, Prataprao Jadhav, emphasized the surge in AYUSH production and global outreach, showcasing a blend of tradition and modern technology.
The recent discovery of 56 enigmatic "UFO galaxies" by the JWST telescope has opened up new possibilities for exploring the secrets of the universe. These red, disc-shaped galaxies were hidden by thick layers of dust and debris, and their unique appearance challenges current understandings of galaxy formation. Astronomers have found that these UFO galaxies share structural similarities with the Milky Way, but contain 50 times more dust. This groundbreaking discovery throws light on the mysterious processes that lead to the creation of cosmic structures and highlights the need for further exploration of the cosmos.
Astronomers have made a groundbreaking discovery by detecting a hot bubble of gas, comparable to Earth's heliosphere, around a sun-like star. This bubble, created by the star's stellar wind, can potentially shield planets from harmful cosmic rays. This first-of-its-kind observation provides valuable insights into the formation of planetary systems and could offer clues about habitability in other parts of the universe.
