Note4Students

From UPSC perspective, the following things are important :

Prelims level: PresVu

Why in the News?

Mumbai-based Entod Pharmaceuticals has announced that the Drug Controller General of India (DCGI) has approved its new eye drop, PresVu, aimed at reducing the dependency on reading glasses for individuals with presbyopia.

What is Presbyopia?

  • Presbyopia is an age-related condition where the eyes gradually lose the ability to focus on nearby objects, typically developing after the age of 40.
  • Spectacles are one of the most commonly recommended solutions for managing presbyopia.

How does PresVu work? 

  • The active ingredient in PresVu is pilocarpine, a compound that contracts the iris muscles, controlling the size of the pupil and helping individuals focus better on nearby objects.
  • PresVu also uses an advanced dynamic buffer technology to adapt to the pH levels of tears, ensuring consistent efficacy and safety for extended use over the years.
  • However, PresVu’s effects are temporary, typically lasting between four to six hours, and it is prescription-only.
  • PresVu should not be used by individuals with iris inflammation.
  • Regular use may lead to side effects such as:
    • Itching and redness
    • Eyebrow pain
    • Muscle spasms in the eyes

Is this a Novel Therapy?

  • Although Entod claims PresVu is novel, the main compound, pilocarpine, has been available in India for decades and is commonly used as a first-line therapy for cataracts.
  • Pilocarpine’s ability to temporarily improve the depth of focus has been explored in other countries, including the United States, where the FDA approved a pilocarpine eye drop for presbyopia in 2021.

What is Helium and why is it used in Rockets?

Note4Students

From UPSC perspective, the following things are important :

Prelims level: Helium

Why in the News?

Two NASA astronauts aboard Boeing’s Starliner will remain on the International Space Station (ISS) for an extended period due to issues with a faulty propulsion system, including helium leaks.

helium

About Helium

  • Helium is inert, meaning it does not react or combust when exposed to other substances.
  • This makes it ideal for pressurization and cooling systems in rockets and spacecraft.
  • With an atomic number of 2, Helium is second lightest element after hydrogen, helping to keep the rocket’s weight low, which is crucial for achieving the necessary speeds and altitudes to reach orbit.
  • It has an extremely low boiling point (-268.9°C), allowing it to stay in a gaseous state in super-cold environments, where many rocket fuels are stored.
  • Though non-toxic, helium cannot be inhaled on its own as it displaces oxygen, which is vital for human respiration.

How is Helium used for space applications?

  • Fuel Tank Pressurization: Helium pressurizes fuel tanks, ensuring a consistent flow of fuel to the rocket’s engines, even as the fuel is burned.
  • Cooling Systems: It also plays a key role in cooling systems, particularly in environments where rocket fuel and oxidizer need to be stored at extremely low temperatures.
  • Maintaining Tank Pressure: As fuel and oxidizer are consumed, helium fills the empty space left behind, ensuring the overall pressure inside the tanks remains stable.

Is Helium prone to leaks?

  • Helium’s small atomic size and low molecular weight make it prone to leaking through tiny gaps or seals in storage tanks and fuel systems.
  • Since helium is rare in Earth’s atmosphere, even minor leaks are easily detectable, making it a valuable tool for spotting potential faults in spacecraft fuel systems.
  • Examples of Leaks:
    • In May, hours before Boeing’s Starliner spacecraft attempted its first astronaut launch, sensors detected a small helium leak in one of its thrusters.
    • After Starliner launched in June, additional leaks were found in space, prompting NASA to return the spacecraft to Earth without its crew.

Alternatives to Helium

  • Argon and Nitrogen: Some rocket launches have experimented with other inert gases like argon and nitrogen, which are sometimes cheaper, but helium remains the industry standard.
  • Ariane 6’s Novel System: Europe’s new Ariane 6 rocket abandoned helium in favor of a pressurization system that converts small amounts of its liquid oxygen and hydrogen into gas for pressurizing the fuel.
    • However, during Ariane 6’s debut launch, this system failed in space, adding to the global rocket industry’s pressurization challenges.

PYQ:

[2012] A team of scientists at Brookhaven National Laboratory included those from India created the heaviest anti-matter (anti-helium nucleus). What is/are the implication/implications of the creation of anti-matter?

Yellow Food Dye can improve Cancer Treatment

Note4Students

From UPSC perspective, the following things are important :

Prelims level: Yellow Food Dye

Why in the News?

Recent research reveals that FD&C Yellow 5, a common food dye, can temporarily make tissue transparent, with potential implications for cancer treatment and medical procedures.

About Yellow Food Dye 

  • FD&C Yellow 5, also known as Tartrazine, is a widely used synthetic food dye found in various snacks, drinks, and processed foods.
  • Approved by the FDA, it is commonly used to give products a vibrant yellow color.

How does it work?

  • The dye has the ability to make tissue transparent is based on its interaction with light, specifically through the Kramers-Kronig relations, a principle in physics.
  • It absorbs blue light, leaving only the red-orange spectrum visible.
  • This alters the refractive index of water, causing it to match the refractive index of fats and proteins in tissue.
  • When the refractive indices match, light can pass through tissue with less scattering, creating the appearance of transparency.

Potential Medical Applications of Yellow Food Dye

  • Cancer Treatment: By making tissues transparent, FD&C Yellow 5 could enhance photodynamic and photothermal therapies, allowing laser light to reach deeper tissues and target cancerous cells more effectively.
  • Vein Visibility: Transparent tissues could help make veins more visible, aiding in procedures like venepuncture for blood draws or injections, particularly in patients with hard-to-see veins.

Antibiotics Resistance

Antibiotic Pollution from the Manufacturing Process

Note4Students

From UPSC perspective, the following things are important :

Prelims level: Antibiotic Pollution

Why in the News?

The World Health Organization (WHO) released its first-ever global guidance on managing antibiotic pollution from manufacturing processes.

What is Antibiotic Pollution?

  • Antibiotic pollution refers to the contamination of natural environments, particularly water and soil, by antibiotics.
  • This pollution occurs when antibiotics are released into ecosystems through various sources, leading to the proliferation of antimicrobial resistance (AMR).
  • AMR happens when bacteria, viruses, fungi, and parasites evolve to resist the effects of antibiotics, making infections harder to treat and posing a significant threat to global health.

How does Antibiotic Pollution occur from the Manufacturing Process?

  • Wastewater Discharge: Antibiotic plants release wastewater with residual antibiotics and active pharmaceutical ingredients (APIs) into local water bodies, contributing to drug-resistant bacteria.
  • Improper Solid Waste Disposal: Unused antibiotics, raw materials, and by-products are often disposed of improperly, contaminating soil and groundwater.
  • Inadequate Treatment: Many facilities lack effective systems to treat pharmaceutical waste, allowing antibiotics to enter the environment.
  • Mass Balance Calculations: Inefficient systems or mismanagement can lead to unintentional antibiotic discharge during recycling and waste estimation.
  • Leaks and Spills: Accidental leaks or spills during manufacturing, transportation, or storage introduce antibiotics into ecosystems.
  • Runoff: Rainwater can carry antibiotics from waste into nearby rivers, lakes, or agricultural land, further contaminating the environment.
