Microorganisms in Medicine and Therapeutics

1.0K
Microorganisms play a fundamental role in vaccine development, gene therapy, and therapeutic production. Their biological properties are harnessed to advance medicine and public health. Beyond immunization, microorganisms contribute to gut health, antibiotic synthesis, and genetic disease treatment.Live Attenuated and Inactivated VaccinesLive attenuated vaccines, such as the measles, mumps, and rubella (MMR) vaccine, utilize weakened forms of pathogens to closely resemble natural infections.

Combination Therapies and Personalized Medicine

5.9K
Combining two or more treatment methods increases the life span of cancer patients while reducing damage to vital organs or tissue from the overuse of a single treatment. Combination therapy also targets different cancer-inducing pathways, thus reducing the chances of developing resistance to treatment.
The combination of the drug acetazolamide and sulforaphane is a good example of combination therapy to treat cancer. The cells in the interior of a large tumor often die due to the hypoxic and...

The Placebo Effect01:54

The Placebo Effect

6.8K
The placebo effect occurs when people's expectations or beliefs influence or determine their experience in a given situation. In other words, simply expecting something to happen can actually make it happen.

Embryonic Stem Cells00:58

Embryonic Stem Cells

32.1K
Embryonic stem (ES) cells are undifferentiated pluripotent cells, meaning they can produce any cell type in the body. This gives them tremendous potential in science and medicine since they can generate specific cell types for use in research or to replace body cells lost due to damage or disease.

Genomics02:02

Genomics

39.8K
Genomics is the science of genomes: it is the study of all the genetic material of an organism. In humans, the genome consists of information carried in 23 pairs of chromosomes in the nucleus, as well as mitochondrial DNA. In genomics, both coding and non-coding DNA is sequenced and analyzed. Genomics allows a better understanding of all living things, their evolution, and their diversity. It has a myriad of uses: for example, to build phylogenetic trees, to improve productivity and...

Threats to Biodiversity01:50

Threats to Biodiversity

26.7K
There have been five major extinction events throughout geological history, resulting in the elimination of biodiversity, followed by a rebound of species that adapted to the new conditions. In the current geological epoch, the Holocene, there is a sixth extinction event in progress. This mass extinction has been attributed to human activities and is thus provisionally called the Anthropocene. In 2019 the human population reached 7.7 billion people and is projected to comprise 10 billion by...

Area of Science:

  • Ophthalmology and Regenerative Medicine

Background:

  • Conventional corneal transplantation (keratoplasty) faces challenges including donor scarcity and immunological rejection.
  • The cornea, a vital avascular eye layer, comprises epithelium, stroma, and endothelium.
  • Regenerative medicine presents a potential paradigm shift from supportive to definitive treatment for corneal diseases.

Purpose of the Study:

  • To review the advancements in corneal regenerative medicine.
  • To highlight the application of regenerative approaches for corneal epithelium, stroma, and endothelium.
  • To discuss the progress towards making corneal regenerative medicine a universal therapeutic option.

Main Methods:

  • Review of existing clinical applications and translational research in corneal regenerative medicine.
  • Focus on understanding corneal stem cell biology for epithelial regeneration.
  • Examination of basic, non-clinical, and clinical studies for stromal and endothelial regenerative therapies.

Main Results:

  • Clinical applications for corneal epithelial regeneration are established, with proven effectiveness and safety of cultivated cell sheet transplantation.
  • Clinical studies for corneal stroma and endothelium regeneration have commenced following foundational research.
  • Ongoing translational research aims to broaden the accessibility of corneal regenerative medicine.

Conclusions:

  • Regenerative medicine is a rapidly advancing field with significant potential to overcome limitations of current corneal transplantation.
  • Successful clinical translation for corneal epithelium paves the way for similar advancements in stroma and endothelium.
