Loss of Tumor Suppressor Gene Functions01:12

Loss of Tumor Suppressor Gene Functions

5.9K
Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
When the tumor suppressor genes develop mutations or are lost, cells start growing out of control, leading to cancer. However, a single functional copy of the tumor suppressor gene is enough for the cells to maintain their normal functions and cell...

Gene Conversion

Other than maintaining genome stability via DNA repair, homologous recombination plays an important role in diversifying the genome. In fact, the recombination of sequences forms the molecular basis of genomic evolution. Random and non-random permutations of genomic sequences create a library of new amalgamated sequences. These newly formed genomes can determine the fitness and survival of cells. In bacteria, homologous and non-homologous types of recombination lead to the evolution of new...

Line Loss01:10

Line Loss

The different configurations of source-load connections include wye (star) and delta connections. The relationship between line and phase voltages and currents varies depending on the configuration. When the source is supplying power, it is transmitted through the wires to the load, and during this transmission, some power is absorbed by the wires, leading to line loss.
Line loss impacts power delivery efficiency in a balanced three-phase circuit. The symmetry in such a circuit simplifies the...

Intrinsically Disordered Proteins02:18

Intrinsically Disordered Proteins

19.3K
Intrinsically disordered proteins are a group of proteins that do not fold into specific three-dimensional structures. Their structural flexibility allows them to complement ordered proteins to perform functions that are inaccessible to rigid structures. They are more common in eukaryotes than prokaryotes and may either be exclusively intrinsically disordered or hybrid proteins, consisting of a mix of ordered and disordered regions. The absence of a rigid structure in these proteins can be...

Conversion of Units01:36

Conversion of Units

35.4K
Sometimes, there is a need to convert from one unit to another one. For instance, reading a cookbook in which quantities are expressed in units of liters or ounces may require conversion of quantities to cups. Or, when looking up directions on how to get to a location, we may be interested to know how many miles we are going to walk. In this case, we would have to convert units of feet or meters to miles.
The first step in the unit conversion is to list the given units and the units required...

Summary
This summary is machine-generated.

Conversion disorder can cause neurological symptoms like vision loss in children. Emergency physicians must consider this diagnosis in unusual cases, even after ruling out organic causes.

Area of Science:

  • Pediatric Neurology
  • Emergency Medicine

Background:

  • Conversion disorder presents with neurological symptoms lacking an organic basis.
  • This condition is rarely seen in emergency departments.

Purpose of the Study:

  • To highlight the presentation of conversion disorder in a pediatric emergency setting.
  • To emphasize the importance of a multidisciplinary approach in diagnosing functional neurological symptoms.

Main Methods:

  • Case report of an 11-year-old girl with lobar pneumonia who developed acute visual loss.
  • Diagnosis established through clinical evaluation by emergency medicine, neurology, ophthalmology, and psychiatry, with negative neuroimaging.
  • Accidental intra-arterial cannula placement was noted as a preceding event.

Main Results:

  • The patient was diagnosed with functional visual loss, a manifestation of conversion disorder.
  • The case underscores the challenge of diagnosing conversion disorder due to atypical presentations.

Conclusions:

  • Emergency physicians should maintain a high index of suspicion for conversion disorder in children presenting with unexplained neurological symptoms.
  • A thorough, stepwise evaluation involving multiple specialties is crucial to exclude organic etiologies and confirm conversion disorder.
