Stimulants01:29

Stimulants

735
Stimulants are substances that enhance neural activity and elevate dopamine levels in the brain, leading to their highly addictive nature. These drugs include cocaine, amphetamines, MDMA, caffeine, and nicotine, each with distinct mechanisms of action and varied health implications.
Cocaine can be administered via snorting, injection, or smoking. It primarily functions by blocking the reuptake of dopamine, resulting in a euphoric high characterized by an intense sensation of happiness and...

Electronic Distance Measuring Instruments

366
Electronic Distance Measuring Instruments (EDMs) are essential tools in modern surveying, offering precise distance measurements by emitting electromagnetic signals and calculating the time required for these signals to travel to a target and return. Two primary types of signals are used in EDMs — light waves and microwaves — each suited to specific environmental and distance requirements. Light-wave-based EDMs utilize either infrared or laser light, providing high accuracy over...

Electron Carriers01:24

Electron Carriers

90.9K
Electron carriers can be thought of as electron shuttles. These compounds can easily accept electrons (i.e., be reduced) or lose them (i.e., be oxidized). They play an essential role in energy production because cellular respiration is contingent on the flow of electrons.
Over the many stages of cellular respiration, glucose breaks down into carbon dioxide and water. Electron carriers pick up electrons lost by glucose in these reactions, temporarily storing and releasing them into the electron...

Electrospray Ionization (ESI) Mass Spectrometry01:12

Electrospray Ionization (ESI) Mass Spectrometry

1.9K
Higher molecular weight biomolecules are nonvolatile compounds that may decompose before ionizing or vaporizing during mass analysis with conventional electron impact ionization methods. Accordingly, electrospray ionization (ESI) is the favored method for vaporizing and ionizing biomolecules as it circumvents rapid fragmentation and enables the recording of mass signals for the entire biomolecule.
ESI utilizes electrical energy to transfer ions from the liquid phase of the sample into the...

Vaporization01:18

Vaporization

37.0K
The physical form of a substance changes by changing its temperature. For example, raising the temperature of a liquid causes the liquid to vaporize (convert into vapor). The process is called vaporization—a surface phenomenon. For vaporization to occur, kinetic energy must be greater than the intermolecular forces that keep molecules bonded. The amount of energy needed to vaporize a quantity of liquid at a given pressure and a constant temperature is called the heat of vaporization. When...

Atomic Emission Spectroscopy: Instrumentation01:22

Atomic Emission Spectroscopy: Instrumentation

1.0K
The instrumentation of atomic emission spectrometry (AES) involves various components, including atomization devices that convert samples into gas-phase atoms and ions. There are two main types of atomization devices: continuous and discrete atomizers.  Continuous atomizers, like plasmas and flames, introduce samples in a constant stream, while discrete atomizers inject individual samples using syringes or autosamplers. The most common discrete atomizer is the electrothermal atomizer.

Area of Science:

  • Public Health
  • Cardiology
  • Addiction Medicine

Background:

  • Cigarette smoking remains a significant public health issue despite decades of intervention.
  • Complete prohibition of tobacco products is unlikely to succeed.
  • Chronic smokers, particularly those with cardiovascular conditions, present a major challenge for cessation.

Purpose of the Study:

  • To explore effective approaches for supporting chronic smokers, especially those with cardiovascular disease, in their journey towards smoking cessation.
  • To evaluate the role of personalized clinical and psychological strategies, including pharmacotherapies and novel nicotine delivery systems, in promoting abstinence.

Main Methods:

  • Clinical and psychological characterization of individual chronic smokers.
  • Assessment of established cessation aids such as varenicline and nicotine replacement therapy.
  • Evaluation of electronic nicotine delivery systems (ENDS) as potentially lower-risk alternatives for smoking transition.

Main Results:

  • Personalized approaches combining clinical and psychological support are crucial for chronic smokers.
  • Varenicline and nicotine replacement therapy are reliable methods to incentivize and support abstinence.
  • Electronic cigarettes and heated tobacco products are considered lower-risk tools offering a smoother transition for some patients, but require cautious use and are not recommended for non-smokers or youth.

Conclusions:

  • A pragmatic and cautious approach to smoking cessation, integrating personalized support and considering newer nicotine delivery systems, can yield favorable results.
  • Discouraging use in non-smokers, particularly young individuals, is essential when discussing electronic nicotine delivery systems.
  • Balancing the potential benefits and risks of all tobacco cessation tools is key to combating cigarette smoking effectively.
