Long-term Depression01:05

Long-term Depression

33.2K
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.

Pilot and Numeric Relaying

485
Pilot relaying is a type of differential protection used in power systems. It compares electrical quantities at the terminals of equipment via a communication channel instead of direct relay interconnection. This method is essential for transmission lines where the terminals are far apart, typically up to 80 km for lines with 69 to 115 kV ratings. Four types of communication channels are used for pilot relaying:

Freezing Point Depression and Boiling Point Elevation

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...

Depressants01:28

Depressants

389
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...

Types of Biopharmaceutical Studies: Controlled and Non-Controlled Approaches

419
Biopharmaceutical studies constitute a vital field aiming to enhance drug delivery methods and refine therapeutic approaches, drawing upon diverse interdisciplinary knowledge. In research methodologies, the choice between controlled and non-controlled studies significantly influences the study's reliability and accuracy.
Non-controlled studies, commonly employed for initial exploration, lack a control group, rendering them susceptible to biases and external influences. In contrast,...

Area of Science:

  • Psychiatry and Psychology
  • Clinical Psychology
  • Mental Health Treatment

Background:

  • Many individuals with depression do not respond to current treatments, and long-term recovery is limited.
  • Anhedonia, a core depression symptom predicting poor prognosis, is often neglected in existing therapies.
  • Augmented Depression Therapy (ADepT) was co-designed with service users to specifically target anhedonia.

Purpose of the Study:

  • To establish proof of concept for ADepT in treating depression.
  • To assess the feasibility and acceptability of ADepT in a pilot trial.
  • To prepare for a definitive trial evaluating ADepT against Cognitive Behavioural Therapy (CBT) for depression, relapse prevention, and wellbeing enhancement.

Main Methods:

  • 80 depressed participants will be randomized 1:1 to ADepT (15 weekly acute sessions + 5 booster sessions) or CBT (20 weekly acute sessions).
  • Clinical and health economic assessments at intake and 6-, 12-, and 18-month follow-ups.
  • Co-primary outcomes: PHQ-9 depression severity and WEMWBS wellbeing at 6 months; process evaluation of mechanisms, implementation, and context.

Main Results:

  • Effect sizes at intake-post and reliable/clinically significant change proportions will be reported for proof of concept.
  • Feasibility and acceptability assessed via recruitment, retention, completion, data completeness, and participant/therapist feedback.
  • Cost of ADepT delivery will be established.

Conclusions:

  • Proceed to a definitive trial if safety, acceptability, feasibility, and proof of concept concerns are resolved.
  • Recruitment, retention, and follow-up data collection must reach at least 60% of the target sample for trial progression.
