Cell and Gene Therapies

Cell and Gene Therapies: The Frontier of Modern Medicine Introduction to  Cell and Gene Therapies In recent decades, cell and gene therapies have emerged as revolutionary tools in the fight against genetic and chronic diseases. These approaches, rooted deeply in molecular biology and biotechnology , offer targeted treatment by either modifying the genetic makeup of cells or using healthy cells to replace or repair damaged ones. Unlike conventional treatments that manage symptoms, these therapies aim to correct the underlying causes of disease. While cell therapy focuses on using living cells to repair or replace damaged tissues, gene therapy involves inserting or altering genes within a patient’s cells to treat a condition. These advanced biotechnological strategies have now made their way from laboratory trials into real-world clinical use, transforming the treatment landscape for previously untreatable diseases.

Biodegradable and Bio-based Plastics As concern over environmental degradation intensifies, biodegradable and bio-based plastics  have become central to the conversation around sustainability. For students, scientists, and policymakers alike, understanding how these materials are engineered and their potential for replacing traditional plastics is key to navigating the next era of environmental responsibility. Understanding Biodegradable and Bio-based Plastics Let’s begin by distinguishing the terms. Biodegradable plastics are designed to decompose through the action of natural organisms, ideally leaving behind non-toxic residues. In contrast, bio-based plastics are derived wholly or partly from biological sources, such as corn starch or sugarcane. While not all bio-based plastics are biodegradable, many combine both traits. What sets these plastics apart is their carbon footprint . Traditional plastics, primarily fossil fuel-based, release significant greenhouse gases du...
