Reinforced Aerated Autoclaved Concrete:

More than 100 schools across England were recently ordered to close buildings because they were constructed using unsafe concrete known as Reinforced Aerated Autoclaved Concrete (RAAC).

  • Reinforced Aerated Autoclaved Concrete (RAAC) is a lightweight, bubbly form of concrete that was used in roofs, floors, and walls between the 1950s and 1990s.
  • It looks like standard concrete, but compared with the “traditional” reinforced material, which is typically denser, Raac is weak and less durable.
  • The material was favoured in construction projects because of its lightweight thermal properties.
  • It is made from a combination of cement, lime, water, and an aeration agent.
  • The mixture is poured into moulds and then subjected to high pressure and heat, known as autoclaving, to create a lightweight, strong, and porous material.
  • It is cheaper also quicker to produce and easier to install.
  • RAAC has excellent thermal insulation properties due to the air bubbles within the material.
  • It helps maintain a comfortable indoor temperature while reducing heating and cooling energy consumption.

Preeclampsia : Recent Study

A recent study revealed that a liquid-biopsy approach that measures DNA-methylation levels in the blood may improve the detection of pregnancies at risk of developing preeclampsia at early stages.

  • Preeclampsia is a serious blood pressure condition that develops during pregnancy.
  • It typically develops after the 20th week of pregnancy.
  • It can also affect other organs in the body and be dangerous for both the mother and her developing fetus
  • People with preeclampsia often have high blood pressure (hypertension) and high levels of protein in their urine (proteinuria).
  • Changes in vision, including temporary loss of vision, blurred vision or light sensitivity
  • The best clinical evidence for the prevention of preeclampsia is the use of low-dose aspirin.
  • A liquid biopsy is a simple and non-invasive alternative to surgical biopsies, which enables doctors to discover a range of information about a tumour through a simple blood sample.

Patulin : Fungus Study

A research team from the Tokyo University of Science (TUS) in Japan discovered a fungus that helps destroy a harmful food toxin, Patulin.

Key finding:

  • The team identified a filamentous fungal strain, Acremonium sp. or “TUS-MM1,” belonging to the genera Acremonium.
  • The scientists then performed various experiments to shed light on the mechanisms by which TUS-MM1 degraded patulin.
  • This involved incubating the mold strain in a patulin-rich solution and focusing on the substances that gradually appeared both inside and outside its cells in response to patulin over time.
  • They found that TUS-MM1 cells transformed any absorbed patulin into desoxypatulinic acid, a compound much less toxic than patulin, by adding hydrogen atoms to it.
  • The team also found that some of the compounds secreted by TUS-MM1 cells can transform patulin into other molecules.
  • Patulin (C7H6O4) is a toxic mycotoxin produced by several types of fungi.
  • It is harmful to a wide range of creatures, including humans, mammals, plants, and microbes.
  • It can grow on damaged or decaying fruits, especially apples.
  • It is responsible for a wide variety of health hazards, including nausea, lung congestion, ulcers, intestinal haemorrhages, and even more serious outcomes—such as DNA damage, immunosuppression and increased cancer risk.

Dhole : Asiatic Wild Dog

Villagers in Shivamogga district, Karnataka, were recently treated to a rare sighting of an Asiatic Wild Dog group, also known as Dholes.

  • Asiatic Wild Dog (Dhole) is a wild canid found in the forests of central, south, and southeast Asia.
  • Scientific Name: Cuon alpinus
  • They are found throughout Eastern and Southeastern Asia.
  • They can be seen as far north as Siberia, as far south as some Malaysian islands, and as far west as the Indian peninsula.
  • They are found in three clusters across India, namely the Western and Eastern Ghats, the central Indian landscape and North East India.
  • The Western and Eastern Ghats is a stronghold region for dholes.
  • Dholes are animals that inhabit dense jungles, steppes, mountains, scrub forests, and pine forests.
  • They vary in colour from charcoal grey to rust red to sandy beige, depending on their habitat.
  • Dholes are highly social animals, and they frequently hunt in packs of 5 to 12. These clans may grow to as many as 30 or 40 members.
  • Conservation status:
    • IUCN Red List: Endangered
    • The Wildlife Protection Act 1972: Schedule II
    • CITES: Appendix II

Myocardial Infarction : New Study

Red blood cells exposed to oxygen deficiency protect against myocardial infarction (heart attack), according to a new study.

  • Red Blood Cells (RBCs) are one of the components of blood. (The others are plasma, platelets and white blood cells.)
  • They deliver oxygen to the tissues throughout the human body.
  • Oxygen turns into energy, and tissues release carbon dioxide.
  • RBCs also transport carbon dioxide back to the lungs to be exhaled.
  • RBCs made are made in the bone marrow.
  • They typically live for about 120 days, and then they die.
  • RBCs contain a protein called haemoglobin, which binds to oxygen in the lungs, forming oxyhemoglobin.
  • Haemoglobin also helps carry carbon dioxide back to the lungs as carbaminohemoglobin.
  • RBCs are biconcave, disc-shaped cells with a dimple in the centre on both sides. This unique shape increases the surface area of the cell, allowing for efficient gas exchange.
  • It is covered with a membrane composed of lipids and proteins and lacks a nucleus.
