Protein-protein Interfaces02:04

Protein-protein Interfaces

14.8K
Many proteins form complexes to carry out their functions, making protein-protein interactions (PPIs) essential for an organism's survival. Most PPIs are stabilized by numerous weak noncovalent chemical forces. The physical shape of the interfaces determines the way two proteins interact. Many globular proteins have closely-matching shapes on their surfaces, which form a large number of weak bonds. Additionally, many PPIs occur between two helices or between a surface cleft and a...

Directing Effect of Substituents: meta-Directing Groups

6.0K
Substituents on the benzene ring that direct an incoming electrophile to undergo substitution at the meta position are called meta directors. All meta directors either have a positive charge on the atom directly bonded to the ring or a partial positive charge. These groups function by withdrawing electrons from the ring through inductive and resonance effects. Consider the carbocation intermediates formed upon the addition of an electrophile on nitrobenzene at the...

Regulation of Stroke Volume01:27

Regulation of Stroke Volume

5.2K
The regulation of stroke volume, which is the amount of blood the heart pumps out during each heartbeat, is critical for maintaining a healthy circulatory system. Stroke volume is influenced by three main factors: preload, contractility, and afterload.
Preload refers to the degree of stretch on the heart before it contracts. It's analogous to the stretching of a rubber band; the more it's stretched, the more forcefully it snaps back. This concept is encapsulated in the Frank-Starling law of the...

Motor Units00:46

Motor Units

62.0K
A motor unit consists of two main components: a single efferent motor neuron (i.e., a neuron that carries impulses away from the central nervous system) and all of the muscle fibers it innervates. The motor neuron may innervate multiple muscle fibers, which are single cells, but only one motor neuron innervates a single muscle fiber.

Motor Units01:13

Motor Units

8.3K
The motor unit is a fundamental component of the neuromuscular system and plays a crucial role in coordinating muscle contractions. It consists of a somatic motor neuron, which connects and controls multiple skeletal muscle fibers, forming a single functional segment. The axon of the motor neuron branches out and establishes synaptic connections known as neuromuscular junctions with individual muscle fibers within the motor unit.
Motor units come in different sizes, with smaller units...

Area of Science:

  • Neuroscience
  • Rehabilitation Medicine
  • Biomedical Engineering

Background:

  • Stroke survivors often experience motor deficits, impacting quality of life.
  • Brain-computer interfaces (BCIs) offer a novel approach by enabling modulation of sensorimotor rhythms.
  • BCIs may promote neurological recovery and motor function improvement post-stroke.

Purpose of the Study:

  • To conduct the first meta-analysis on the clinical effectiveness of BCI-based post-stroke motor rehabilitation.
  • To evaluate the impact of BCI training on motor impairment scores in stroke survivors.

Main Methods:

  • Systematic search of MEDLINE, CENTRAL, and PEDro databases for randomized controlled trials.
  • Inclusion of nine studies with 235 post-stroke survivors meeting specific motor performance outcome criteria.
  • Application of a random-effects inverse variance method for calculating summary effect size.

Main Results:

  • BCI training led to motor improvements exceeding the minimal clinically important difference in six of the included studies.
  • A significant standardized mean difference of 0.79 (95% CI: 0.37 to 1.20) in upper limb Fugl-Meyer Assessment scores was observed compared to control groups.
  • Evidence of BCI-induced functional and structural neuroplasticity at a subclinical level was noted.

Conclusions:

  • BCI technology demonstrates potential as an effective intervention for post-stroke upper limb rehabilitation.
  • BCI training shows a medium to large effect size in improving motor function.
  • Further research with larger sample sizes is recommended to solidify these findings.
