Bio-taxis for Cancer treatment

Context: The researchers at the Indian Institute of Science have developed a new way to deliver cancer vaccines using the body's natural transport system.

They have developed an antigen that can attach itself to a natural protein called serum albumin in the blood and travel to the nearest lymph node, where the immune system is activated. This method avoids the need for artificial carriers that can cause side effects and allows for more targeted delivery of cancer vaccines.

Bio-taxis:

  • Bio-taxis, also known as targeted drug delivery or targeted therapy, is a developing area of cancer treatment that utilises the body's natural transport mechanisms to deliver therapeutic agents directly to cancer cells.
  • The goal of bio-taxis is to enhance the effectiveness of treatment while reducing the side effects associated with traditional chemotherapy (minimising the damage to healthy cells).
  • One example of bio-taxis for cancer treatment involves the use of antibodies or nanoparticles that are designed to bind to specific molecules on the surface of cancer cells. These targeted therapies can attach to/hitchhike on proteins in the bloodstream, such as serum albumin, until they reach their target. Once they reach the tumour, the therapeutic agents can be released to kill the cancer cells.

Cancer cells and their detection: 

  • Cancer is a condition where cells grow and divide uncontrollably due to a disruption in their DNA. 
  • Normally, our immune system fights against invaders using antibodies produced in the lymph nodes, which are small organs in the human body. Antigens are molecules that trigger the production of antibodies to fight invaders (trigger immune response). 
  • In the case of cancer, the cancer cells are clever (they evade the immune system) and can shut down the production of antibodies that target and eliminate them.
  • To develop a cancer vaccine, scientists modify or mimic an antigen found on the surface of cancer cells to turn up or turn on this antibody production. These antigens can prod the immune system into producing antibodies. But how to take the antigens to the lymph nodes?

How to carry antigens to lymph nodes?

  • Traditionally, delivering cancer antigens (molecules that trigger immune response) to lymph nodes involved hitching them onto artificial carriers like viruses or proteins. However, these carriers can be bulky, cause side effects, and even sometimes hinder the immune response (reduce the production of antibodies against cancer cells).
  • The new approach uses the body's natural transport system. Scientists designed an antigen with a special attachment that allows it to bind to serum albumin, the most abundant protein in blood plasma. This "hitchhiking" on albumin carries the antigen directly to lymph nodes, where immune system activation happens. This method is simpler and avoids the problems associated with artificial carriers.
    • They synthesised a specific carbohydrate called Tn, which is found on the surface of various cancer cells, in the laboratory. 
    • They combined this carbohydrate with a long-chain chemical that has an affinity for oils, creating bubble-like structures called micelles. These micelles strongly bind to human serum albumin. 
    • When the micelle latches onto albumin, it breaks apart, and the individual antigen molecules bind to the available albumin. 
  • This finding suggests that there may not be a need to search for viruses, proteins, or other carriers because serum albumin alone can effectively transport the antigens. This breakthrough provides a new way to deliver cancer vaccines.

Carbohydrate-based antigens:

  • In recent years, scientists have been focusing on carbohydrates found on the surfaces of cancer cells to develop these antigens.
  • Both normal and cancer cells have carbohydrates on their surfaces, but cancer cells have heavily truncated (shortened) carbohydrates.
  • Hence, Carbohydrate-based antigens can play a crucial role in the development of cancer vaccines.

Pradhan Mantri Jan Arogya Yojana (PMJAY)

Context: Since the inception of the Pradhan Mantri Jan Arogya Yojana (PMJAY), 34.27 crore cards have been issued, and 6.5 crore beneficiaries have received treatment across 30,000 empanelled hospitals. Despite its extensive reach, the program has encountered significant challenges, including substantial payment backlogs owed to hospitals by the government.

This financial strain has led some hospitals to either refuse or limit the number of PMJAY patients they accept, raising concerns about whether the scheme needs a design overhaul to address these challenges.

About Pradhan Mantri Jan Arogya Yojana (PMJAY): 

Launched in: 2018

  • Type of scheme: Centrally sponsored scheme
  • Subsumed scheme: Rashtriya Swasthya Bima Yojana (RSBY) and the Senior Citizen Health Insurance Scheme (SCHIS).
  • Key features: It is an entitlement-based scheme that targets the beneficiaries as identified by latest Socio-Economic Caste Census (SECC) data.
    • It offers a sum insured of Rs.5 lakh per family for secondary care and tertiary care hospitalisation to the bottom 40 per cent of the population of India.
    • It covers the cost of hospitalization, pre-hospitalization, medication, and post-hospitalization during the treatment of tertiary and secondary care procedures.
    • The Ayushman Card is like a pre-paid card worth Rs 5 lakh, which can be used to avail free treatment at more than 27,000 empanelled hospitals.
    • Every hospital must provide Pradhan Mantri Arogya Mitras (PMAMs) to assist beneficiaries.
    • The National Health Authority (NHA) has been constituted as an autonomous entity under the Society Registration Act, 1860 for effective implementation of PM-JAY in alliance with state governments.
    • The State Health Agency (SHA) is the apex body of the State Government responsible for the implementation of AB PM-JAY in the State.

Do Marriage need to be registered

Context: The Supreme Court ruled that a Hindu marriage is not valid ‘unless performed with ceremonies in proper form’. This was despite the couple in question having an official marriage certificate.

Marriage

Marriage, a social institution present in virtually every culture, serves several functions and comes in various types:

  • C.P. Kottack: Marriage is a socially recognized relationship between a socially recognized male (Husband) and a socially recognized female (Wife) so that the children born to the wife are accepted as the offspring of both the husband and wife.
  • Functions of Marriage:
    • Social Stability and Order: Marriage provides a framework for organizing familial relationships, establishing legal rights and responsibilities, and maintaining social order within a community.
    • Reproduction and Family Formation: Traditionally, marriage has been the primary institution for procreation and raising children. It provides a stable environment for the upbringing of offspring.
    • Emotional Support and Companionship: Marriage offers emotional and psychological support through companionship, intimacy, and partnership. Spouses often rely on each other for love, encouragement, and comfort.
    • Economic Cooperation: Marriage facilitates economic cooperation and pooling of resources between spouses, enabling them to share financial burdens, manage household expenses, and plan for the future together.
    • Cultural and Religious Significance: Many cultures and religions attach profound cultural and religious significance to marriage, viewing it as a sacred union with spiritual implications.
    • Legal and Social Recognition: Marriage grants legal and social recognition to the relationship between spouses, conferring rights such as inheritance, healthcare decision-making, and spousal benefits.
  • Types of Marriage:
    • Monogamy: Monogamy involves the union of two individuals, typically one man and one woman, forming an exclusive partnership. It is the most common form of marriage in many societies.
    • Polygamy:
      • Polygyny: Polygyny permits a man to have multiple wives simultaneously. This practice has historical and cultural roots in various societies, though it is less common today.
      • Polyandry: Polyandry allows a woman to have multiple husbands simultaneously. It is rarer than polygyny and is found in specific cultures, often in areas with scarce resources.
    • Group Marriage: Also known as communal marriage or collective marriage, group marriage involves multiple men and women forming a marital union together. This type of marriage is relatively uncommon and often associated with alternative lifestyle communities.
    • Same-Sex Marriage: Same-sex marriage involves the union of two individuals of the same gender. While historically marginalized or prohibited in many societies, it has gained legal recognition and acceptance in an increasing number of countries.
    • Arranged Marriage: Arranged marriage involves families or intermediaries selecting spouses for individuals based on various factors such as compatibility, social status, and familial considerations. While prevalent in some cultures, the degree of consent and autonomy can vary significantly.

Each type of marriage reflects the values, norms, and traditions of the society in which it occurs, shaping individuals' lives and relationships in diverse ways.

About Ruling

The Supreme Court Ruling:

  • The Supreme Court ruled that a Hindu couple, despite possessing an official marriage certificate, was deemed to have "never acquired the status of husband and wife."
  • This ruling was based on the fact that the couple's marriage was registered under the Hindu Marriage Act, 1955 (HMA) before they performed the wedding rituals.
  • Consequently, the couple did not need to obtain a divorce because they were considered to have never been married in the first place.

Understanding Solemnized Marriage:

  • Solemnizing a marriage entail conducting an official marriage ceremony, including appropriate rituals.
  • In India, marriage is governed by personal laws and statutes like the Special Marriage Act, 1954 (SMA).
  • Different religions have their own requirements for a valid marriage, such as rituals for Hindus and Christians, and a contractual agreement for Muslims.

Registered Marriages vs. Solemnized Marriages:

  • Terms like "court marriage" or "registered marriage" typically refer to civil marriages under the Special Marriage Act, 1954 (SMA), conducted without religious rituals.
  • Marriages under personal laws (e.g., HMA for Hindus) require adherence to religious rituals for validity.
  • The registration of marriages solemnized under personal laws is governed by respective statutes, such as Section 8 of the Hindu Marriage Act, 1955.

Implications of Marriage Registration:

  • Marriage registration serves various official purposes, such as spousal visa applications and joint medical insurance.
  • However, the absence of marriage registration does not inherently invalidate a marriage, as registration alone does not confer validity.

Legal Presumptions and Evidence:

  • Various legal presumptions exist regarding marriage, such as the presumption of marriage when cohabitation is continuous.
  • Evidence of a valid marriage includes proof of performing rituals, long-term cohabitation, and acceptance by family and friends.
  • While a marriage certificate holds corroborative value, it is not considered conclusive evidence on its own in legal proceedings.

Significance in Legal Matters:

  • Validity of marriage is crucial in legal contexts like bigamy trials and inheritance disputes.
  • Proof of performing valid rituals, evidence of cohabitation, and acceptance by family and friends are essential in establishing the validity of marriage.
  • A marriage certificate supplements evidence but is not sole proof of marriage validity.

DigiLocker Platform

What is DigiLocker?

  • DigiLocker is a flagship initiative of the Ministry of Electronics & IT (MeitY) under the Digital India programme, launched in 2015.
  • DigiLocker platform operates as an App to store users’ digital records. The app is aimed at letting users access, verify, and store essential documents in a digital wallet so that they are easy to retrieve and present to officials when required.
  • The issued documents in DigiLocker system are deemed to be at par with original physical documents as per Rule 9A of the Information Technology (Preservation and Retention of Information by Intermediaries providing Digital Locker facilities) Rules, 2016. 
  • Utility: The app can be used to prove users’ identity and their credentials. E.g., when applying for a passport, reviewing marksheets, or proving one’s identity during travel. 
  • DigiLocker has been built on top of open-source digital platforms. 
    • Open-source digital platforms typically consist of software and tools that are freely available for anyone to use, modify, and distribute.
    • Core code behind DigiLocker is built using freely available open-source software. This allows anyone to examine the code, understand how it works, and even contribute improvements. This fosters collaboration and can lead to a more secure and reliable system.
  • Users’ data: As of May 2024, the app has over 270 million registered users, while nearly 6.7 billion documents — like Aadhaar, insurance policy papers, PAN records, and driving licences — have been retrieved through it.

How secure is DigiLocker?

  • DigiLocker is ideally maintained with standard security measures in place including 2048 Bit RSA SSL encryption, multi-factor authentication (OTP verification), consent systems, timed log outs, and security audits.
  • No DigiLocker data is shared with third parties and data is encrypted in transit. Examples of data collected include files and documents (optional), your name, email (optional), and user IDs. 
  • However, any government database that stores citizens’ information and documents is inevitably an attractive target for hackers who steal user data and sell it on the dark web.
  • On June 2, 2020, DigiLocker posted a notice about a “potential vulnerability in the sign-up flow,” that could have led to accounts being compromised. However, due to a CERT-In alert and another independent researcher, DigiLocker said that the vulnerability was patched within a day of getting the alert, and that user data was safe. 

Benefits of DigiLocker: 

  • Paperless solution to prove users’ identity and their credentials. 
  • Allows users to access their e-documents irrespective of their physical location. 
  • Prevents fake, poor quality print copies, and outdated documents that miss key details.
  • Eliminates the need to carry separate sets of documents while travelling. 

Limitations of DigiLocker:

While DigiLocker offers a compelling alternative to physical documents, but it is not quite a complete replacement yet.

  • Not universally accepted: While acceptance is growing, some organisations might still require physical documents. 
  • Digital Literacy Gap: Not everyone has access to technology or the skills to use DigiLocker.
  • Infrastructure Dependence: Reliance on internet connectivity can be a hurdle in some areas.
