Disease: lead toxicity

Surface Display of Multiple Metal-Binding Domains in Deinococcus radiodurans Alleviates Cadmium and Lead Toxicity in Rice

mycolabadmin

Scientists created genetically engineered bacteria (Deinococcus radiodurans) that can grab and absorb harmful heavy metals like cadmium and lead from soil and water. When these specially designed bacteria colonize rice plant roots, they protect the plants from metal toxicity by removing metals from the environment and boosting the plant’s natural defense systems. This approach could help make rice safer to eat by preventing dangerous metal accumulation in crops grown in contaminated areas.

Redox-Active Metal–Organic Framework Nanocrystals for the Simultaneous Adsorption, Detection, and Detoxification of Heavy Metal Cations

mycolabadmin

This research demonstrates how specially designed metal-organic framework materials can effectively remove toxic heavy metals like mercury, lead, and cadmium from water. The most effective material, cobalt-based HHTP, can capture these metals through both chemical reactions and physical binding, making it highly efficient. The researchers also successfully coated these materials onto fabrics, creating wearable water filters that can simultaneously purify water and detect contamination levels.

Avian toxicoses: a review

mycolabadmin

Pet and wild birds can be poisoned by many common substances including metals found in cage materials, kitchen cookware fumes, toxic plants, chocolate, salt, and rodent poison. Symptoms vary by toxin but can include difficulty breathing, weakness, seizures, and bleeding. Treatment focuses on removing the source, supportive care, and specific antidotes when available, though diagnosis is often challenging due to the small size of birds.

Investigation of the simulated microgravity impact on heavy metal biosorption by Saccharomyces cerevisiae

mycolabadmin

This research shows that yeast commonly used in bread and beer production can absorb dangerous heavy metals from water, and this ability is even stronger in simulated weightlessness conditions. The metal-yeast complexes remain stable as they pass through the digestive system, making them safe for astronauts and potentially useful for cleaning contaminated drinking water in the food and beverage industry.

Bibliometric analysis of European publications between 2001 and 2016 on concentrations of selected elements in mushrooms

mycolabadmin

Researchers reviewed 200 European studies from 2001-2016 examining how mushrooms absorb heavy metals from soil. They found that mushrooms, especially edible species, can accumulate dangerous metals like cadmium, lead, and mercury, with the highest contamination in mushrooms from polluted industrial areas. Turkey, Poland, Spain, and Czech Republic led research efforts on this topic. Scientists increasingly used health risk assessment methods to determine safe consumption levels of mushrooms from different habitats.
