Drug Control Governance: Regulatory Bodies and Their Impact01:03

Drug Control Governance: Regulatory Bodies and Their Impact

328
Drug control governance involves the oversight and regulation of pharmaceuticals to ensure their safety and efficacy while preventing illegal drug use and trafficking. Regulatory bodies, including the US Food and Drug Administration (FDA) and the European Union's European Medicines Agency (EMA), play a central role in this process. These agencies evaluate the safety and efficacy of drugs before they can be marketed. They fund clinical trials and assess the benefits and risks associated with...

Method of Joints: Problem Solving II01:30

Method of Joints: Problem Solving II

790
Consider a truss structure with frictionless joints fixed to a wall and roller support. If a force of 150 N is applied to joint A, the forces in each member of the truss can be determined using the method of joints.

Method of Joints: Problem Solving I

1.5K
The method of joints is a commonly used technique to analyze the forces in structural trusses. The method is based on the principle of equilibrium, which assumes that the truss members are connected by frictionless pins. The forces at each joint can be determined by considering the equilibrium of the forces acting on that joint. Consider a truss structure with two forces of 20 N and 10 N acting at joints C and D, respectively. The method of joints can be used to determine the forces FCB, FDC,...

Development of the Limb Synovial Joints01:07

Development of the Limb Synovial Joints

1.9K
Joints form during embryonic development in conjunction with the formation and growth of the associated bones. The embryonic tissue that gives rise to all bones, cartilage, and connective tissues of the body is called mesenchyme.
The mesenchymal stem cells differentiate into chondrocytes that form the hyaline cartilage, and later the cartilaginous model of the bone. This model further transforms into a bone. This process is known as endochondral ossification.
During development, the limbs...

Functional Classification of Joints01:09

Functional Classification of Joints

5.7K
Functional Classification of Joints
The functional classification of joints is determined by the amount of mobility between the adjacent bones. Joints are functionally classified as a synarthrosis or immobile joint, an amphiarthrosis or slightly moveable joint, or as a diarthrosis, a freely moveable joint. Fibrous and cartilaginous joints can be functionally classified as either synarthroses  or amphiarthroses, whereas all synovial joints are classified as diarthroses.

Introduction to Joints00:58

Introduction to Joints

4.2K
The adult human body usually has 206 bones, and except for the hyoid bone in the neck, each bone is connected to at least one other bone. Joints are the location where bones come together. Many joints allow for movement between the bones. At these joints, the articulating surfaces of the adjacent bones can move smoothly against each other. However, the bones of other joints may be joined by connective tissue or cartilage. These joints are designed for stability and provide little or no...

Summary
This summary is machine-generated.

Standardizing cannabis doses with a Standard Joint Unit (SJU) is crucial for safety and research. Developing an SJU requires addressing challenges like varying THC levels and legal status, drawing lessons from the Standard Drink (SD).

Area of Science:

  • Drug policy and harm reduction
  • Cannabis research and public health

Background:

  • Standardized cannabis dosing is a priority for research, policy, clinical interventions, and consumer safety.
  • A Standard Joint Unit (SJU) is proposed to mirror the Standard Drink (SD) for cannabis, aiding preventive and intervention models.

Purpose of the Study:

  • To explore challenges and achieve consensus on developing a Standard Joint Unit (SJU) for cannabis.
  • To identify core values, challenges, and facilitators for SJU implementation.

Main Methods:

  • A back-casting foresight method was employed during a workshop at the Lisbon Addictions Conference 2019.
  • Thirty-two professionals from 13 countries and 10 disciplines participated in the consensus-building process.

Main Results:

  • Defined SJU core values: ease of use, universality, THC focus, accuracy, and accessibility.
  • Identified key challenges: changing use patterns, compound/route heterogeneity, THC variability, and evolving legal status.
  • Highlighted facilitators: prior standardization experience, funding, multi-stakeholder support, user prevalence, and legislative changes.

Conclusions:

  • Three initial steps for SJU implementation by 2030 were proposed: forming a task force, expanding national data, and linking SJU to "risky use" concepts.
  • Consensus was reached on the need for and characteristics of a SJU to improve cannabis harm reduction and safety.
