Forces Acting on Chromosomes02:11

Forces Acting on Chromosomes

4.0K
During mitosis, chromosome movements occur through the interplay of multiple piconewton level forces. In prometaphase, these forces help in chromosome assembly or congression at the equatorial plane, eventually leading to their alignment at the metaphase plate. The forces acting on the chromosomes are space and time-dependent; therefore, they vary with the position of the chromosomes as the cell progresses through mitosis. 
Microtubules and motor proteins exert two types of forces on...

Direct-Acting Cholinergic Agonists: Pharmacokinetics

1.9K
Direct-acting cholinergic agonists, such as synthetic choline esters and naturally occurring alkaloids, exert their effects by enhancing the actions of acetylcholine and stimulating the parasympathetic nervous system. Synthetic choline esters share structural similarities with acetylcholine. For example, they have a positively charged quaternary ammonium or onium group, contributing to their hydrophilic characteristics. As a result, they are poorly absorbed in the body through oral...

Drugs Acting on Autonomic Ganglia: Stimulants01:23

Drugs Acting on Autonomic Ganglia: Stimulants

2.1K

Ganglionic stimulants activate NM nicotinic receptors in autonomic ganglia, falling into two categories: nicotine mimetics [e.g., lobeline, dimethylpiperazine, tetramethylammonium] and muscarinic receptor agonists [e.g., muscarine, methacholine]. The first category's action is rapid and blocked by nicotinic receptor antagonists, while the second category's action is delayed and blocked by atropine-like agents. Nicotine, an alkaloid, affects the heart rate by stimulating...

Drugs Acting on Autonomic Ganglia: Blockers01:28

Drugs Acting on Autonomic Ganglia: Blockers

1.7K
Ganglionic blockers inhibit autonomic activity by blocking nicotinic receptors in the autonomic ganglia, suppressing impulse transmission. These blockers lack selectivity between sympathetic and parasympathetic ganglia and are ineffective as neuromuscular junction antagonists. They can be categorized into two groups:

Reversible and Irreversible Processes01:14

Reversible and Irreversible Processes

5.8K
The thermodynamic processes can be classified into reversible and irreversible processes. The processes that can be restored to their initial state are called reversible processes. It is only possible if the process is in quasi-static equilibrium, i.e., it takes place in infinitesimally small steps, and the system remains at equilibrium However, these are ideal processes and do not occur naturally. An ideal system undergoing a reversible process is always in thermodynamic equilibrium within...

Diode: Reverse bias01:14

Diode: Reverse bias

2.0K
A diode is reverse-biased when the positive terminal of an external voltage source is connected to the n-type material and the negative terminal to the p-type material. This configuration opposes the natural direction of current flow through the diode, effectively increasing the width of the depletion region and the barrier potential. The reverse bias condition produces a minimal leakage current, primarily due to minority charge carriers. This leakage becomes significant when the reverse...

Summary

Long-acting reversible contraceptive (LARC) users are less likely to use dual methods compared to non-LARC hormonal contraceptive users. Factors like age, race, education, and STI history also influence dual method use.

Area of Science:

  • Reproductive health
  • Contraceptive technology
  • Sexual health

Background:

  • Dual method use, combining condoms with other contraceptives, is crucial for preventing unintended pregnancies and sexually transmitted infections (STIs).
  • Understanding patterns of dual method use across different contraceptive methods is essential for public health interventions.
  • The Contraceptive CHOICE Project provides valuable data on contraceptive behavior and outcomes.

Purpose of the Study:

  • To compare dual method use rates between users of long-acting reversible contraceptives (LARC) and non-LARC hormonal contraceptives.
  • To identify demographic, behavioral, and psychosocial factors associated with dual method use in contraceptive users.

Main Methods:

  • Secondary analysis of the prospective, observational Contraceptive CHOICE Project cohort study.
  • Inclusion of 6744 women who initiated a contraceptive method and continued use at 6 months post-enrollment.
  • Primary outcome measured was the rate of dual method use at 6 months post-enrollment.

Main Results:

  • Dual method use was lower among LARC users (32%) compared to non-LARC hormonal contraceptive users (45%) (p < .01).
  • LARC users were less likely to report dual method use (aRR 0.76, 95% CI 0.70-0.83) after adjustment.
  • Factors associated with dual method use included younger age (<25), Black race, lower education, single status, baseline dual method use, prior STI, partner willingness for condom use, and higher condom self-efficacy.

Conclusions:

  • LARC users demonstrate lower dual method use compared to non-LARC hormonal contraceptive users.
  • Individual and partner-related factors significantly influence dual method use.
  • Further research is needed to ascertain if reduced dual method use among LARC users elevates STI risk.
