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).

Summary
This summary is machine-generated.

Levamisole, a veterinary drug adulterating cocaine, can cause severe skin necrosis and vasculitis. Early diagnosis and a multidisciplinary approach are crucial for managing this condition.

Area of Science:

  • Veterinary Medicine
  • Toxicology
  • Dermatology

Background:

  • Levamisole is a veterinary drug with antihelminthic, chemotherapeutic, and immunomodulatory properties.
  • It is frequently used as an adulterant in illicit cocaine.
  • Levamisole adulteration in cocaine is associated with severe adverse effects.

Observation:

  • This article details two cases of suspected levamisole-induced vasculitis.
  • Patients presented with purpuric retiform lesions and skin necrosis.
  • These findings suggest a link between levamisole exposure and vasculitic syndromes.

Findings:

  • Levamisole can potentiate the sympathomimetic effects of cocaine.
  • Adverse effects include neutropenia, agranulocytosis, and severe cutaneous reactions.
  • Vasculitis is a significant, albeit uncommon, complication of levamisole exposure.

Implications:

  • There is no established diagnostic or treatment protocol for levamisole-induced vasculitis.
  • A multidisciplinary team approach involving toxicology, dermatology, and rheumatology is essential.
  • Increased awareness and diagnostic vigilance are needed to manage this emerging health issue.
