Sustainable Development01:43

Sustainable Development

15.2K
As the human population continues to grow and use resources, we must be mindful of our planet’s natural limits. Sustainable development provides a pathway to maintain and improve human life now while also ensuring that future generations will have the resources that they need. The long-term success of sustainability efforts rests on understanding the interplay between human actions and ecological systems.

Language Development01:22

Language Development

956
Children master language quickly and with relative ease, supported by both biological predisposition and reinforcement. B. F. Skinner (1957) proposed that language is learned through reinforcement, while Noam Chomsky (1965) argued that language acquisition mechanisms are biologically determined.
The critical period for language acquisition suggests that the ability to acquire language is at its peak early in life. As people age, this proficiency decreases. Language development begins very...

Development of the Lymphatic System01:15

Development of the Lymphatic System

2.2K
The development of lymphatic tissues and vessels in embryonic life begins around the fifth week. These structures originate from the mesoderm layer, with lymph sacs emerging from developing veins.
The first lymph sacs to form are the paired jugular lymph sacs located at the junction of the internal jugular and subclavian veins. From these sacs, lymphatic capillary plexuses extend to the thorax, upper limbs, neck, and head, eventually forming lymphatic vessels. Each jugular lymph sac maintains a...

Development of Immunocompetence

The initiation of cell-mediated immunity can be observed as early as the third month of fetal growth, with active antibody-mediated immunity following approximately one month later.
The initial cells that migrate from the fetal thymus settle within the skin and epithelial tissues lining the mouth, digestive tract, and in females, the uterus and vagina. These cells, including skin-based dendritic cells, serve as antigen-presenting cells, playing a key role in T cell activation.
Subsequent T...

Development of the Heart01:27

Development of the Heart

2.8K
The development of the human heart, a crucial organ, commences from the mesoderm on the 18th or 19th day after fertilization. This process initiates in the cardiogenic area, a group of mesodermal cells at the embryo's head end, which evolves into elongated strands known as cardiogenic cords. These cords undergo a transformation to form hollow-centered endocardial tubes.
As the embryo undergoes lateral folding, these paired tubes approach each other, merging into a single primitive heart...

Fruit Development, Structure, and Function01:58

Fruit Development, Structure, and Function

25.5K
Fruits form from a mature flower ovary. As seeds develop from the ovules contained within, the ovary wall undergoes a series of complex changes to form fruit. In some fruits, such as soybeans, the ovary wall dries; in other fruits, such as grapes, it remains fleshy. In some cases, organs other than the ovary contribute to fruit formation; such fruits are called accessory fruits.

Area of Science:

  • Neurology
  • Biomedical Engineering
  • Medical Devices

Background:

  • Qualitative blink reflex assessments are standard for neurological status evaluation in critical care and rehabilitation.
  • Quantitative blink reflex measurements have a strong evidence base for diagnosing neurological disorders but lack clinical adoption.
  • A need exists for objective, portable, and non-invasive neurological health metrics.

Purpose of the Study:

  • To develop and validate a high-speed videography-based device for quantitative blink reflex analysis.
  • To assess the device's viability as a non-invasive diagnostic tool for neurological health.

Main Methods:

  • Development of a high-speed videography system to trigger, record, and analyze blink reflexes.
  • Pilot study comparing device measurements against electromyography (EMG), the current gold standard.
  • Analysis of device's ability to provide fast, objective, and quantitative blink reflex metrics.

Main Results:

  • The videography device successfully triggered, recorded, and analyzed blink reflexes.
  • Measurements obtained by the device demonstrated viability when compared to published EMG data.
  • The device provides fast, objective, and quantitative metrics of the blink reflex.

Conclusions:

  • The developed high-speed videography device is a promising tool for objective blink reflex measurement.
  • The device has potential as a non-invasive diagnostic assessment for neurological health.
  • This technology could address the unmet clinical need for portable and objective neurological evaluation tools.
