Induced-fit Model01:13

Induced-fit Model

89.2K
Most chemical reactions in cells require enzymes—biological catalysts that speed up the reaction without being consumed or permanently changed. They reduce the activation energy needed to convert the reactants into products. Enzymes are proteins, that usually work by binding to a substrate—a reactant molecule that they act upon.
Enzymes exhibit substrate specificity, meaning that they can only bind to certain substrates. This is mainly determined by the shape and chemical...

Induced Pluripotent Stem Cells

28.0K
Stem cells are undifferentiated cells that divide and produce different types of cells. Ordinarily, cells that have differentiated into a specific cell type are post-mitotic—that is, they no longer divide. However, scientists have found a way to reprogram these mature cells so that they “de-differentiate” and return to an unspecialized, proliferative state. These cells are also pluripotent like embryonic stem cells—able to produce all cell types—and are therefore...

Induced Pluripotent Stem Cells

Stem cells are undifferentiated cells that divide and produce different cell types. Ordinarily, cells that have differentiated into a specific cell type are terminally differentiated; however, scientists have found a way to reprogram these mature cells so that they dedifferentiate and return to an unspecialized, proliferative state. These cells are pluripotent like embryonic stem cells—able to produce all cell types—and are called induced pluripotent stem cells (iPSCs).

Induced Electric Dipoles01:28

Induced Electric Dipoles

4.8K
A permanent electric dipole orients itself along an external electric field. This rotation can be quantified by defining the potential energy because the external torque does work in rotating it. Then, the potential energy is minimum at the parallel configuration and maximum at the antiparallel configuration. While the former is a stable equilibrium, the latter is an unstable equilibrium.
Since the absolute value of potential energy holds no physical meaning, its zero value can be chosen as per...

Induced Electric Fields

4.6K
The fact that emfs are induced in circuits implies that work is being done on the conduction electrons in the wires. What can possibly be the source of this work? We know that it’s neither a battery nor a magnetic field, as a battery does not have to be present in a circuit where current is induced, and magnetic fields never do any work on moving charges. The source of the work is in fact an electric field that is induced in the wires. For example, if a stationary conductor is placed in a...

Spontaneous and Induced Mutations01:30

Spontaneous and Induced Mutations

2.3K
Spontaneous mutations arise infrequently during DNA replication due to errors in the process. A key factor behind these errors is tautomeric shifts in nitrogenous bases, where bases transition from keto to enol forms or amino to imino forms. This shift can alter base-pairing rules, leading to mutations. Additionally, reactive oxygen species (ROS) arising from aerobic metabolism can damage DNA, resulting in depurination (loss of a purine base) or depyrimidination (loss of a pyrimidine base).

Area of Science:

  • Dermatology
  • Medical Case Reports

Background:

  • Erythema ab igne (EAI) is a skin condition resulting from chronic heat exposure.
  • Modern heat sources, including laptops, contribute to its prevalence across demographics.

Observation:

  • A 25-year-old man presented with a year of asymptomatic, reticulated hyperpigmentation and an abdominal erosion.
  • The patient regularly placed a laptop directly on his abdomen for extended periods.

Findings:

  • The patient's symptoms were diagnosed as erythema ab igne.
  • This condition arises from prolonged exposure to temperatures ranging from 43-47°C.

Implications:

  • EAI is an evolving clinical issue with modern heat sources like laptops.
  • Prompt diagnosis via guided questioning can prevent irreversible skin damage, including ulcers and potential skin cancers.
