Opioid Analgesics: Synthetic and Semisynthetic Opioids01:15

Opioid Analgesics: Synthetic and Semisynthetic Opioids

1.1K
Synthetic and semisynthetic opioids are pivotal in pain management and tackling opioid addiction. Semisynthetic opioids, including morphinans (morphine derivatives), oxycodone, oxymorphone, hydrocodone, and hydromorphone, have improved pharmacokinetic profiles compared to morphine. Additionally, heroin and 6-MAM (6-Monoacetylmorphine) show better CNS penetration than morphine due to heightened lipid solubility. Hydromorphone, a potent opioid, undergoes hepatic metabolism to form the active...

Opioid Receptors: Overview

4.6K
Opioid receptors, including the mu (μ, MOR), delta (δ, DOR), and kappa (κ, KOR) types, belong to the rhodopsin family of G protein-coupled receptors. These receptors are located throughout the central and peripheral nervous systems and in non-neuronal tissues such as macrophages and astrocytes. Opioid receptor ligands can be categorized into agonists or antagonists. Highly selective agonists include [d-Ala2, MePhe4, Gly(ol)5]-enkephalin or DAMGO for MOR, [D-Pen2,...

Opioid Analgesics: Morphine and Other Natural Cogeners01:20

Opioid Analgesics: Morphine and Other Natural Cogeners

1.1K
Opioids are a class of drugs that mimic endogenous opioid peptides and act on opioid receptors, and help in pain relief. These compounds are classified as natural, synthetic, or semi-synthetic. Natural opioids, like morphine, codeine, and thebaine, are derived from the opium poppy plant (Papaver somniferum or Papaver album) and are termed opiates. Synthetic opioids are artificial, while semi-synthetic opioids combine natural and synthetic compounds. Morphine, a prototypical opioid, possesses a...

Drugs Affecting GI Tract Motility: Opioids as Antidiarrheal Agents

700
Diarrhea, a condition marked by frequent loose or watery bowel movements, can be triggered by multiple factors such as viral or bacterial infections, food intolerances, anxiety, medications, and digestive disorders. Symptoms may include abdominal pain, bloating, nausea, and cramping. Severe or prolonged diarrhea can lead to complications like electrolyte imbalances, malnutrition, and dehydration if left untreated.
Opioids, widely used antidiarrheal agents, mitigate diarrhea by slowing down...

The Fluid Mosaic Model01:34

The Fluid Mosaic Model

179.5K
The fluid mosaic model was first proposed as a visual representation of research observations. The model comprises the composition and dynamics of membranes and serves as a foundation for future membrane-related studies. The model depicts the structure of the plasma membrane with a variety of components, which include phospholipids, proteins, and carbohydrates. These integral molecules are loosely bound, defining the cell’s border and providing fluidity for optimal function.

Quantum Numbers

It is said that the energy of an electron in an atom is quantized; that is, it can be equal only to certain specific values and can jump from one energy level to another but not transition smoothly or stay between these levels.

Area of Science:

  • Social Media Analytics
  • Public Health Surveillance
  • Epidemiology

Background:

  • Rising opioid use and overdose rates necessitate improved data collection.
  • Targeting resources and responding to trends requires enhanced public health surveillance methods.

Purpose of the Study:

  • To assess Twitter data's utility in identifying geographic disparities in opioid discussions.
  • To determine correlations between opioid-related Twitter topics and overdose death rates.

Main Methods:

  • Filtered 10 billion tweets (July 2009-October 2015) for opioid keywords.
  • Utilized Latent Dirichlet Allocation (LDA) to identify 50 opioid-related topics.
  • Quantified correlations between topic distribution and geographic/demographic data, including overdose death rates.

Main Results:

  • Analyzed 84,023 tweets from 72,211 unique users across the US.
  • Opioid topics significantly correlated with Census Bureau divisions and state/county overdose death rates.
  • Identified themes like drug-related crime, online purchasing, and news discussions linked to overdose rates.

Conclusions:

  • Geographic variations in Twitter discussions reflect regional opioid concerns.
  • Twitter data analysis can identify topics correlated with opioid overdose death rates.
  • Social media monitoring offers a potential method for tracking emerging opioid trends.
