Oogenesis02:07

Oogenesis

64.4K
In human women, oogenesis produces one mature egg cell or ovum for every precursor cell that enters meiosis. This process differs in two unique ways from the equivalent procedure of spermatogenesis in males. First, meiotic divisions during oogenesis are asymmetric, meaning that a large oocyte (containing most of the cytoplasm) and minor polar body are produced as a result of meiosis I, and again following meiosis II. Since only oocytes will go on to form embryos if fertilized, this unequal...

Reproductive Cloning01:27

Reproductive Cloning

30.9K
Reproductive cloning is the process of producing a genetically identical copy—a clone—of an entire organism. While clones can be produced by splitting an early embryo—similar to what happens naturally with identical twins—cloning of adult animals is usually done by a process called somatic cell nuclear transfer (SCNT).
Somatic Cell Nuclear Transfer
In SCNT, an egg cell is taken from an animal and its nucleus is removed, creating an enucleated egg. Then a somatic...

Necrosis01:16

Necrosis

4.9K
Necrosis is considered as an “accidental” or unexpected form of cell death that ends in cell lysis. The first noticeable mention of “necrosis” was in 1859 when Rudolf Virchow used this term to describe advanced tissue breakdown in his compilation titled “Cell Pathology”.
Morphological Manifestations of Necrosis
Necrotic cells show different types of morphological appearance depending on the type of tissue and infection. In coagulative necrosis, cells become...

Skeleton and Calcium Homeostasis01:21

Skeleton and Calcium Homeostasis

4.8K
Calcium is not only the most abundant mineral in bone but also the most abundant mineral in the human body. Calcium ions are needed for bone mineralization, tooth health, heart rate regulation and strength of contraction, blood coagulation, the contraction of smooth and skeletal muscle cells, and the regulation of nerve impulse conduction. The average calcium level in the blood is about 10 mg/dL. When the body cannot maintain this level, a person will experience hypo or hypercalcemia.

Spontaneous Chemical Reactions
Spontaneous redox reactions occur abundantly in nature. The chemical reaction occurring in a disposable AA battery powering our remote controls is one such example of a spontaneous redox reaction. Another example is the immersion of coiled copper wire into an aqueous silver nitrate solution. The reaction shows a gradual, visually impressive color change from colorless to bright blue and the formation of a grey precipitate on the copper wire. In this experiment,...

Whole Body Regeneration01:33

Whole Body Regeneration

3.4K
Regeneration is the process of restoring injured or lost tissues, organs, or body parts. While simpler organisms generally show greater ability to regenerate their whole body, few complex animals show similarly exceptional regeneration. For example, planarian flatworms have a unique regenerative potential making them a popular study organism among biologists to understand the mechanisms of whole body regeneration. Other organisms, such as hydra, also show extreme regeneration potential;...

Area of Science:

  • Biotechnology
  • Clinical Chemistry
  • Medical Diagnostics

Background:

  • Theranos promised revolutionary blood testing using microvolumes and novel technology outside labs.
  • The company attracted substantial investment but lacked independent validation of its technology.
  • Theranos misled stakeholders, using traditional analyzers instead of its proprietary methods, leading to its downfall.

Purpose of the Study:

  • To analyze the Theranos case study in biotechnology and clinical diagnostics.
  • To comment on new ventures related to Theranos and their potential.
  • To emphasize lessons learned from past failures in medical technology development.

Main Methods:

  • Review of Theranos's business practices and technological claims.
  • Analysis of the impact of Theranos's deception on investors and patients.
  • Commentary on emerging trends and competition in the point-of-care diagnostics field.

Main Results:

  • Theranos's technology was not independently validated and relied on conventional methods.
  • Misleading claims led to significant financial investments and subsequent legal consequences.
  • New companies with similar objectives are emerging, facing a competitive landscape.

Conclusions:

  • The Theranos case serves as a critical lesson in the importance of scientific validation and transparency in biotechnology.
  • Future ventures must prioritize ethical practices and robust technology to regain trust.
  • The evolving field of diagnostics presents both opportunities and formidable challenges for new entrants.
