Long-term Depression01:05

Long-term Depression

33.3K
Long-term depression, or LTD, is one of the ways by which synaptic plasticity—changes in the strength of chemical synapses—can occur in the brain. LTD is the process of synaptic weakening that occurs over time between pre and postsynaptic neuronal connections. The synaptic weakening of LTD works in opposition to synaptic strengthening by long-term potentiation (LTP) and together are the main mechanisms that underlie learning and memory.

Boiling Point Elevation
The boiling point of a liquid is the temperature at which its vapor pressure is equal to ambient atmospheric pressure. Since the vapor pressure of a solution is lowered due to the presence of nonvolatile solutes, it stands to reason that the solution’s boiling point will subsequently be increased. Vapor pressure increases with temperature, and so a solution will require a higher temperature than will pure solvent to achieve any given vapor pressure, including one...

Depressants

426
Depressant drugs, including alcohol and sedative-hypnotics, diminish central nervous system activity by enhancing the action of gamma-aminobutyric acid (GABA), a neurotransmitter that reduces brain activity and promotes relaxation. These substances can have various therapeutic uses but also pose significant risks, especially when misused or combined.
Alcohol is a common depressant that can induce a sense of relaxation and reduced inhibition at low doses. Contrary to its occasional...

Proteomics

9.7K
A proteome is the entire set of proteins that a cell type produces. We can study proteomes using the knowledge of genomes because genes code for mRNAs, and the mRNAs encode proteins. Although mRNA analysis is a step in the right direction, not all mRNAs are translated into proteins.
Proteomics is the study of proteomes' function. It involves the large-scale systematic study of the proteome to denote the protein complement expressed by a genome. Scientist Mark Wilkins coined the term...

Depression: Overview01:18

Depression: Overview

878
Depression is a prevalent mental illness marked by persistent sadness and lack of interest in previously enjoyable activities. It can take several forms, including major depression, persistent depressive disorder, and bipolar I and II disorders. Symptoms range from emotional changes like chronic worry to physical changes like sleep disturbances and suicidal thoughts. From a neurobiological perspective, depression is believed to be triggered by abnormalities in the brain's prefrontal cortex,...

Area of Science:

  • Neuroscience
  • Biochemistry
  • Genomics

Background:

  • Major depressive disorder (MDD) is a complex, multifactorial condition with incompletely understood molecular underpinnings.
  • Current diagnostic and treatment selection processes for MDD can be lengthy, impacting patient outcomes.

  • To review recent advancements in proteomic biomarkers for major depressive disorder.
  • To identify potential protein candidates for a diagnostic and treatment response biomarker panel.
  • To explore the biological systems associated with these potential biomarkers.

Main Methods:

  • Comprehensive literature review of proteomic studies in major depressive disorder.
  • Analysis of identified proteins for their potential role in disease diagnosis and treatment response.
  • Categorization of proteins based on associated biological pathways.

Main Results:

  • Several potential proteomic biomarkers have been identified from recent research.
  • These candidate proteins are associated with key biological systems including immune, inflammatory, and coagulatory pathways.
  • Additional links to energy metabolism, oxidative stress, cell communication, and oligodendrogenesis were noted.
