Structure-Activity Relationships and Drug Design01:28

Structure-Activity Relationships and Drug Design

1.8K
Drug design is a dynamic field that involves discovering and developing new medications based on specific biological targets. This process heavily relies on structure-activity relationships (SAR) and quantitative structure-activity relationships (QSAR) to guide the design and optimization of efficient drugs.
SAR studies the intricate relationship between a drug's chemical structure and biological activity. It focuses on understanding how modifications to a drug's structure can influence...

Local Anesthetics: Chemistry and Structure-Activity Relationship

6.7K
Local anesthetics (LAs) are drugs that induce a temporary loss of sensation in a limited body area, preventing pain. Cocaine was the first local anesthetic discovered in the late 19th century. Cocaine is a benzoic acid ester obtained from the leaves of coca shrubs and was often used for its psychotropic effects. Cocaine was first isolated in 1860 by Albert Niemann. Sigmund Freud studied the physiological actions of cocaine. Carl Koller later introduced it into clinical practice in 1884 as a...

Relationship Formation

46.3K
What do you think is the single most influential factor in determining with whom you become friends and whom you form romantic relationships? You might be surprised to learn that the answer is simple: the people with whom you have the most contact. This most important factor is proximity. You are more likely to be friends with people you have regular contact with. For example, there are decades of research that shows that you are more likely to become friends with people who live in your dorm,...

Cholinergic Antagonists: Chemistry and Structure-Activity Relationship01:29

Cholinergic Antagonists: Chemistry and Structure-Activity Relationship

2.8K
Cholinergic antagonists bind to cholinergic receptors and limit the effects of acetylcholine and other cholinergic agonists. Based on the specific cholinergic receptor affinity, these antagonists are classified as muscarinic or nicotinic. Anticholinergics interrupt parasympathetic innervations while sympathetic innervations remain uninterrupted. Muscarinic antagonists are also called 'muscarinic antagonists', 'antimuscarinics', or 'parasympatholytics'. Nicotinic...

Adrenergic Agonists: Chemistry and Structure-Activity Relationship

3.9K
Adrenergic agonists' structure-activity relationship (SAR) determines their selectivity and efficacy. These agonists comprise a phenylethylamine moiety with an aromatic ring and an ethylamine side chain.
Aromatic ring substitutions: Substituting the aromatic ring with –OH groups at positions 3 and 4 yields catecholamines (e.g., epinephrine), which have a high affinity for adrenoceptors. Hydrogen bonding between –OH groups and receptors enhances adrenergic activity.
Separation of...

Ending Relationships01:28

Ending Relationships

205
The dissolution of intimate relationships presents complex emotional and psychological challenges, particularly when emotional bonds are strong, the relationship is long-standing, and perceived alternatives are limited. This distress often intensifies in romantic breakups, where the initiator may experience greater turmoil than the rejected partner. Contributing factors include residual attachment, guilt over causing pain, and uncertainty about how to manage the situation. The stress is further...

Summary
This summary is machine-generated.

Dual-task gait speed better predicts daily activity in stroke survivors than single-task speed. This finding highlights the importance of cognitive demands in real-world walking for community mobility after stroke.

Area of Science:

  • Neurorehabilitation
  • Biomechanics
  • Physical Therapy

Background:

  • Traditional single-task gait speed is insufficient for predicting community ambulation in stroke survivors.
  • Real-world walking involves complex cognitive and motor demands not captured by single-task assessments.

Purpose of the Study:

  • To determine if dual-task gait speed explains additional variance in daily ambulatory activity beyond single-task gait speed.
  • To investigate the predictive value of gait speed under dual-task conditions for community-dwelling stroke survivors.

Main Methods:

  • Twenty-eight community-dwelling stroke survivors (mean age 58.2 years) performed gait and cognitive tasks under single- and dual-task conditions.
  • Daily ambulatory activity was objectively measured using a physical activity monitor.
  • Regression analysis was used to assess the contribution of single- and dual-task gait speed to predicting daily activity.

Main Results:

  • Single-task gait speed accounted for 15.3% of the variance in daily ambulatory activity (P=0.04).
  • Inclusion of dual-task gait speed in the model significantly increased the explained variance by an additional 20.6% (P=0.04).

Conclusions:

  • Gait speed measured during attention-demanding (dual-task) conditions offers improved prediction of daily ambulatory activity in stroke survivors.
  • Assessing gait under dual-task conditions may provide a more ecologically valid measure of functional mobility post-stroke.
