Autism Spectrum Disorder01:19

Autism Spectrum Disorder

1.1K
Autism spectrum disorder (ASD) is a neurodevelopmental condition marked by persistent deficits in social communication and interaction alongside restrictive and repetitive behaviors or interests. ASD is sometimes accompanied by intellectual impairment.
These core symptoms manifest differently among individuals, ranging from mild to severe. The disorder's complexity extends beyond its clinical presentation, encompassing a diverse range of biological, cognitive, and sociocultural influences.

The Electromagnetic Spectrum02:37

The Electromagnetic Spectrum

65.1K
The electromagnetic spectrum consists of all the types of electromagnetic radiation arranged according to their frequency and wavelength. Each of the various colors of visible light has specific frequencies and wavelengths associated with them, and you can see that visible light makes up only a small portion of the electromagnetic spectrum. Because the technologies developed to work in various parts of the electromagnetic spectrum are different, for reasons of convenience and historical...

The Electromagnetic Spectrum

33.6K
Electromagnetic waves are categorized according to their wavelengths and frequencies, giving the electromagnetic spectrum. These waves are classified as radio, infrared, ultraviolet, etc. Radio waves refer to electromagnetic radiation with wavelengths ranging from millimeters to kilometers. Radio waves are commonly used for audio communications (i.e., radios) and typically result from an alternating current in the wires of a broadcast antenna. They cover a broad wavelength range and are used...

IR Spectrum01:19

IR Spectrum

2.1K
When infrared (IR) radiation passes through a molecule, the bonds stretch or bend by absorbing the radiation. This absorption creates the molecule's absorption spectrum, which is the plot of its percentage transmittance versus wavenumber.
Transmittance is defined as the ratio of the radiant power passing through a sample to that from the radiation's source. Multiplying the transmittance by 100 gives the percent transmittance (%T), which varies between 100% (no absorption) and 0%...

Mass Spectrum01:23

Mass Spectrum

4.5K
A mass spectrum is the graphical representation of the relative abundance of the charged fragments in an analyte plotted against their mass-to-charge ratio (m/z). The plot's x-axis represents the ratio of the mass of the charged fragment to the number of charges it carries. The y axis of the plot represents the relative abundance of each charged species. The relative abundance is calculated from the signal intensity of each charged species recorded at the detector. The most intense signal (the...

UV–Vis Spectrum01:30

UV–Vis Spectrum

2.1K
When light passes through a substance, a portion of the light is absorbed while the remaining light is reflected or transmitted. If the molecule absorbs light between the wavelengths of 180–400 nm range, the UV spectrum is obtained, and if it absorbs light in the 400–780 nm wavelength range, the visible spectrum is obtained.     
The UV–Vis spectrum of a molecule is the plot of its absorbance versus wavelength. The plot is drawn by taking molar...

Area of Science:

  • Neuroimmunology
  • Central Nervous System Disorders

Background:

  • Neuromyelitis optica spectrum disorder (NMOSD) is a rare autoimmune disease targeting the central nervous system.
  • Key clinical features include optic neuritis, myelitis, and area postrema syndrome.
  • Without treatment, NMOSD leads to significant disability, including blindness and motor deficits, with a high mortality rate within five years.

Purpose of the Study:

  • To provide a comprehensive review of the pathogenesis, clinical features, diagnosis, and management of NMOSD.
  • To highlight the importance of early diagnosis and aggressive treatment in preventing long-term disability.

Main Methods:

  • Review of existing literature on NMOSD pathogenesis, clinical presentation, diagnostic criteria, and treatment strategies.
  • Analysis of disease course, disability accrual related to relapses, and the role of specific antibodies.

Main Results:

  • Approximately 75% of NMOSD patients have antibodies against aquaporin-4 (AQP4).
  • Disability in NMOSD is relapse-dependent, unlike the progressive course seen in multiple sclerosis.
  • Aggressive treatment of relapses with high-dose steroids and plasma exchange is crucial.

Conclusions:

  • Long-term immunosuppression is essential for relapse prevention in NMOSD.
  • Understanding NMOSD pathogenesis, particularly the role of AQP4 antibodies, guides effective management.
  • Prompt and appropriate management can significantly alter the prognosis and improve outcomes for NMOSD patients.
