Can Cancer Be Cured With Just One Injection?

Can Cancer Be Cured With Just One Injection?

South Korean researchers have developed a phototherapy technology that can increase the efficiency of reducing the pain of chemotherapy and minimizing side effects after treatment. Let’s see how they have succeeded in achieving this medical feat and see if cancer can be cured with just one injection.

Crux of the Matter

What Is Chemotherapy?
It is a medical treatment that uses one or more anti-cancer drugs as part of a standardized regimen of making the patients cancer-free or prolonging their life by reducing symptoms.

What New Method Have Researchers Found Now?
A research team from South Korea’s KU-KIST have developed a cancer-targeted phototherapeutic agent that promises complete elimination of cancer cells without side effects.

How Is This Possible?
It involves only one injection and repeated phototherapy, which involves exposure to fluorescent light bulbs or other sources of light like halogen lights, sunlight, and LEDs.

What Have They Used?
Peptides, that selectively target cancer tissues and assemble themselves in a specific order only for tumour removal. On being injected into a living body, it is activated by the body temperature. Thus, eradicates cancer cells without affecting surrounding normal cells.

Have They Tested This?
Yes. The agent was injected into a mouse model implanted with a tumor, and the photosensitizer was stored around the tumor and was continuously released for 2 to 4 weeks.

No toxicity was found to destroy the surrounding tissues and major organs, even with repeated exposure to light, making it safe for human usage.

Other Conditions Treatable By Phototherapy

  • Skin disorders
  • Some cancers and precancers
  • Sleep disorders
  • Hyperbilirubinemia Jaundice or jaundice in babies
  • Skin-related cancer symptoms

  • The 62nd element on the periodic table is Samarium, which is used to treat a range of cancers, including lung cancer. And hence the famous show, Breaking Bad, has a total of 62 episodes over 5 seasons.
  • Radiation therapy or radiotherapy is a therapy using ionizing radiation, generally as part of cancer treatment to control or kill malignant cells and normally delivered by a linear accelerator. Radiation therapy may be curative in a number of types of cancer if they are localized to one area of the body.
  • The word chemotherapy was coined in the early 1900s by Paul Ehrlich as meaning any use of chemicals to treat any disease, such as the use of antibiotics (antibacterial chemotherapy). Ehrlich was not optimistic that effective chemotherapy drugs would be found for the treatment of cancer.

Types Of Fast Charging Battery Solutions

Types Of Fast Charging Battery Solutions

Many startups are working on solutions for the energy sector, on a global level. Here are some fast-charging battery methods from some of these promising startups that can prove revolutionary for usage in electric vehicles.

Crux of the Matter

Addionics’s 3D Nanostructure Cathodes
A 3D nanostructure for battery cathodes allows for faster charging and discharging without any loss in energy storage capacity

The 3D Ni nanowire meshes exhibit a semi-ordered structure which has some of the highest combined porosity [measure of the void (i.e. “empty”) spaces in a material] and surface-to-volume ratio among macroporous metals (pores of a size greater than 50 nm.)

GBatteries’ Adaptive Pulse Charing
Used for Li-on and Li-polymer batteries, it determines overcharged, undercharged, normal, and degraded operating conditions, improving the battery life of cells for electric cars.

How Do They Do That?
An AI-based tech uses adaptive pulse charging algorithm for lower impedance periods or less opposition of a circuit to current. Thus, batteries don’t heat up during ultra-fast charging

Geyser Batteries – Aqueous Electrochemistry
Aqueous electrochemistry, wherein the solvent is mostly water, in order to combine the energy storage of batteries with the durability and power of supercapacitors in a single system.

What Are Supercapacitors?
They are electrochemical energy storage devices, which store and release energy by reversible adsorption and desorption of ions at the interfaces between electrode materials and electrolytes.

Invertedpower – DC Fast Charging
This fast charging method converts alternating current (AC) to direct current (DC) for reducing the charging time of a battery. 

How Is This Done?
The tech bypasses the onboard charger of EVs and sends this direct current directly to the battery. So charging is not limited by the performance of the onboard charger and is much quicker.

Knowing Dr. Viswanathan Shanta: Face of Cancer Care

Knowing Dr. Viswanathan Shanta: Face of Cancer Care

Dr Viswanathan Shanta (1927-2021), the Indian oncologist who was best known for her efforts towards making quality and affordable cancer treatment accessible in the nation, passed away earlier this week. Let’s know more about the Padma Bhushan awardee’s life in this piece dedicated to her contributions.

Crux of the Matter

Who Was She?
She was born on 11 March 1927, at Mylapore, Chennai, into a family of Nobel Laureates: C.V. Raman (grand uncle) and S. Chandrasekar (uncle). This was a time when Indian women generally entered the field of obstetrics and gynaecology.

Work In Cancer Institute (WIA)
Also called Adyar Cancer Institute, it is an Indian non-profit cancer treatment and research centre based in Chennai, wherein initially there were 2 doctors, Shanta and Krishnamurthi. She worked there from 1955 to 2021, where she became the director (1980-1997) and chairperson thereafter.

What Is Oncology?

  • Oncology is a branch of medical science, which deals with the prevention, diagnosis, and treatment of cancer.
  • There are 3 major areas of the branch: medical, surgical, and radiation.

Member Of Tamil Nadu State Planning Commission For Health
As a member, she was a strong advocate of early detection of cancer and the need to change public perception of the disease, particularly the extreme fear and hopelessness associated with it.

International Presence
She served as a member of several national and international committees on health and medicine, as the WHO Advisory Committee on Health.

In an era when specialised medical care in India has become highly commercialised, Dr. Shanta strives to ensure that the Institute remains true to its ethos, `Service to all.’ Its services are free or subsidised for some 60% of its 100,000 annual patients […] 87-year-old Shanta still sees patients.

This Battery Can Charge Your EV in 5 Minutes

This Battery Can Charge Your EV in 5 Minutes

Thought only mobile phones can be charged in this much time? Well, Israeli company StoreDot has plans of delivering 100 miles of charge to an EV battery in 5 minutes in 2025. Let’s see how this battery works and what it means for EV users in times ahead.

Crux of the Matter

Who Has Made The Tech?
Israeli company StoreDot Ltd. will manufacture this battery, while the lithium-ion samples have been produced by their Chinese strategic partner, Eve Energy Co.

Where Was It Demonstrated?
Earlier demonstrated in their drones and phones, this time a two-wheeled scooter used their battery. It is slated for a 2025 mass rollout, as per CEO Doron Myersdorf.

How Far Can The EV Travel Then?
With the available charging infrastructure, 100 miles of charge can be provided to an EV by charging the battery for 5 minutes.

Saves Users From Range Anxiety
If the experience of charging an EV is similar to fuelling a petrol/diesel car, the anxiety of ‘running out of charge in the middle of nowhere or sitting in the charging station for a long time’ goes away.

Isn’t This Possible With Existing Batteries?
Well, existing Li-ion batteries use graphite as an electrode, into which the lithium ions are pushed for storing charge. But on being rapidly charged, the ions can get congested, converts into metal and then short circuits the battery.

Then What Does StoreDot Battery Use?
It replaces graphite with semiconductor nanoparticles, into which ions can pass more quickly. These particles are currently based on Germanium, which is easier to handle but would be based on silicon later, which is cheaper.

I think technologies [like StoreDot’s] could start entering the market. But, since they will be more difficult to manufacture, we’re likely to initially only see them in niche markets that are highly performance-driven and not as price-sensitive.
