Gene Conversion

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...

Panic Disorder

Panic Disorder

Panic disorder is an anxiety disorder characterized by recurrent and sudden minutes-long episodes of intense fear, known as panic attacks. These attacks may feel like heart attacks and often happen without warning or a specific cause. They can include symptoms such as rapid heart rate, shortness of breath, chest pain, trembling, sweating, dizziness, and a sense of helplessness. During a panic attack, individuals may feel as though they are experiencing a heart attack or are in a...

Conversion of Units

Conversion of Units

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...

Radical Formation: Homolysis

Radical Formation: Homolysis

A bond is formed between two atoms by sharing two electrons. When this bond is broken by supplying sufficient energy, either two electrons can be taken up by one atom forming ions by the cleavage called heterolysis, or the two electrons are shared by two atoms, with one each creating radicals by the cleavage called homolysis.

Psychosurgery

Psychosurgery

Psychosurgery, the surgical alteration or permanent removal of brain tissue to alleviate severe psychological conditions, stands as one of the most radical and controversial treatments in the history of mental health care. Its development and application have evolved significantly, marked by dramatic shifts in scientific understanding and ethical perspectives.
Historical Development of Psychosurgery
In the 1930s, Portuguese neurologist Antonio Egas Moniz introduced a surgical procedure designed...

Summary

Conversion disorder, including psychogenic nonepileptic seizures and functional movement disorders, presents diagnostic and therapeutic challenges. Early, honest communication of the diagnosis is crucial for patient management.

Area of Science:

Neurology
Psychiatry

Context:

Conversion disorder remains a significant clinical challenge, often co-occurring with organic conditions.
Two primary subtypes, psychogenic nonepileptic seizures and functional movement disorders, are recognized.

Purpose:

To review the diagnostic, therapeutic, and nosological aspects of conversion disorder.
To highlight advancements in diagnosis and understanding of underlying brain mechanisms.

Summary:

Recent reevaluations of clinical signs and neurological investigations aid in reducing misdiagnosis rates.
Functional neuroimaging offers insights into the brain mechanisms of conversion phenomena.
There is an ongoing debate regarding the classification of conversion symptoms, balancing "functional neurological symptoms" with the concept of "hysteria" and dissociation.
