Frontiers: Honeybees have been helpful insects since ancient centuries, and this benefit is not limited to being a honey producer only

Posted by in categories: biotech/medical, chemistry, food, nanotechnology

After the bee stings a person, pain, and swelling occur in this place, due to the effects of bee venom (BV). This is not a poison in the total sense of the word because it has many benefits, and this is due to its composition being rich in proteins, peptides, enzymes, and other types of molecules in low concentrations that show promise in the treatment of numerous diseases and conditions. BV has also demonstrated positive effects against various cancers, antimicrobial activity, and wound healing versus the human immunodeficiency virus (HIV). Even though topical BV therapy is used to varying degrees among countries, localized swelling or itching are common side effects that may occur in some patients. This review provides an in-depth analysis of the complex chemical composition of BV, highlighting the diverse range of bioactive compounds and their therapeutic applications, which extend beyond the well-known anti-inflammatory and pain-relieving effects, showcasing the versatility of BV in modern medicine. A specific search strategy was followed across various databases; Web of sciences, Scopus, Medline, and Google Scholar including in vitro and in vivo clinical studies.to outline an overview of BV composition, methods to use, preparation requirements, and Individual consumption contraindications. Furthermore, this review addresses safety concerns and emerging approaches, such as the use of nanoparticles, to mitigate adverse effects, demonstrating a balanced and holistic perspective. Importantly, the review also incorporates historical context and traditional uses, as well as a unique focus on veterinary applications, setting it apart from previous works and providing a valuable resource for researchers and practitioners in the field.

Bees are commercially beneficial insects that have been around since the Cretaceous age of the Mesozoic Era. They also help fertilize many different crops. Bees are helpful, but their capacity to administer excruciating and poisonous stings constitutes a risk. Thankfully, most honeybees are not hostile to people and only resort to violence if they perceive danger (Pucca et al., 2019). Apis mellifera is the most often used honeybee species for agricultural pollination globally. All bee products, particularly venom, and honey, have been used for centuries, and their medicinal properties have been described in holy writings such as the Bible and the Quran (Ali, 2024; Dinu et al., 2024). Bee venom (BV) treatment involves injecting honeybee venom into the human body to cure various ailments. For over 5,000 years, this technique has been used in complementary therapies.

“Astonishing” — Scientists Unveil First Blueprint of the Most Complex Molecular Machine in Human Biology

Posted by in categories: biotech/medical, genetics, nanotechnology, neuroscience

Scientists at the Centre for Genomic Regulation (CRG) in Barcelona have developed the first comprehensive blueprint of the human spliceosome, the most complex and intricate molecular machine found in every cell. This groundbreaking achievement, over a decade in the making, was published in the journal Science.

The spliceosome edits genetic messages transcribed from DNA, allowing cells to create different versions of a protein from a single gene. The vast majority of human genes – more than nine in ten – are edited by the spliceosome. Errors in the process are linked to a wide spectrum of diseases including most types of cancer, neurodegenerative conditions, and genetic disorders.

The sheer number of components involved and the intricacy of its function has meant the spliceosome has remained elusive and uncharted territory in human biology – until now.

MIT Scientists Develop New Way To Treat the Brain — Without Invasive Implants or Genetic Tweaks

Posted by in categories: bioengineering, biotech/medical, genetics, nanotechnology, neuroscience

Novel magnetic nanodiscs could provide a much less invasive way of stimulating parts of the brain, paving the way for stimulation therapies without implants or genetic modification, MIT researchers report.

The scientists envision that the tiny discs, which are about 250 nanometers across (about 1/500 the width of a human hair), would be injected directly into the desired location in the brain. From there, they could be activated at any time simply by applying a magnetic field outside the body. The new particles could quickly find applications in biomedical research, and eventually, after sufficient testing, might be applied to clinical uses.

The development of these nanoparticles is described in the journal Nature Nanotechnology, in a paper by Polina Anikeeva, a professor in MIT’s departments of Materials Science and Engineering and Brain and Cognitive Sciences, graduate student Ye Ji Kim, and 17 others at MIT and in Germany.

Advanced sensing tech can detect lung cancer in your exhaled breath

Posted by in categories: biotech/medical, chemistry, nanotechnology

Researchers have developed a nanoscale sensor that detects lung cancer simply by analyzing the levels of a chemical called isoprene in your breath. The team believes its breakthrough could unlock a non-invasive, low-cost method to catch the disease early, and potentially save a lot of lives.

When the human body breaks down fat in a process called lipolytic cholesterol metabolism, isoprene is released in exhaled breath. As it turns out, a decline in isoprene can indicate the presence of lung cancer. The team, led by researchers at China’s Zhejiang University, leveraged this insight through its work and developed an innovative gas sensing material to create a screening process.

The challenge with spotting biomarkers in breath is that your system needs to be able to differentiate between volatile chemicals, withstand the natural humidity of exhaled breath, and detect tiny quantities of specific chemicals. In the case of isoprene, you’d need sensors capable of detecting levels of the chemical in the parts-per-billion (ppb) range.
