Development of Blood Vessels01:07

Development of Blood Vessels

1.5K
The development of the vascular system in a fetus is a complex and intricate process that begins as early as 15 to 16 days post-conception. This process starts outside the embryo, specifically in the mesoderm of the yolk sac, chorion, and connecting stalk. Approximately two days later, the formation of blood vessels occurs within the embryo itself.
The initial formation of this system is facilitated by the small amount of yolk present in the ovum and yolk sac. Blood vessels originate from...

Synthetic Biology

Synthetic biology is an interdisciplinary science that involves using principles from disciplines such as engineering, molecular biology, cell biology, and systems biology. It involves remodeling existing organisms from nature or constructing completely new synthetic organisms for applications such as protein or enzyme production, bioremediation, value-added macromolecule production, and the addition of desirable traits to crops, to name a few.

Synthetic Disvision of Polynomials

191
Synthetic division is an efficient algorithmic approach for dividing a polynomial by a linear binomial of the form x - c, where c is a real number. This method is helpful due to its streamlined process, which avoids the more cumbersome steps involved in the traditional long division of polynomials. It simplifies computation and serves as a practical tool for evaluating polynomials and identifying their factors.To perform synthetic division, one begins by listing the coefficients of the...

Layers of the Epidermis01:21

Layers of the Epidermis

8.5K
The epidermis, the outermost layer of the skin, is composed of several distinct layers. From deep to superficial, the layers of the epidermis are as follows:
Stratum Basale
Stratum basale, also known as the stratum germinativum, is the deepest layer of the epidermis. It is composed of a single layer of actively dividing cells called basal cells or basal keratinocytes. These cells constantly undergo cell division to replenish the upper layers of the epidermis. Additionally, melanocytes, which...

Structure of Blood Vessels01:15

Structure of Blood Vessels

9.7K
Blood is circulated throughout the human body through a network of blood vessels called the circulatory system. This system includes arteries that transport blood from the heart to various body parts. These arterial pathways divide into smaller vessels until they reach the arterioles, which further split into capillaries. It is within these minuscule capillaries that the exchange of nutrients and waste products takes place. After this exchange, the blood is collected by venules, which fuse to...

Anatomy of Blood Vessels01:20

Anatomy of Blood Vessels

2.8K
The vascular system, an integral part of the circulatory system, comprises various blood vessels that play crucial roles in maintaining the body's homeostasis. These blood vessels form a complex and efficient circulatory network. The three primary categories of blood vessels are the arteries, veins, and capillaries.
Arteries
Arteries circulate oxygenated blood from the heart, except the pulmonary artery, which transports deoxygenated blood to the lungs. Large arteries, such as the aorta,...

  • Surgical Simulation
  • Biomedical Engineering
  • Microsurgery Training

Background:

  • Microsurgery skills are crucial but challenging to acquire.
  • Simulation is increasingly vital for microvascular training.
  • Ethical considerations necessitate improved non-living models for animal replacement.

Purpose of the Study:

  • To develop and evaluate a novel three-layered synthetic vessel for microsurgical training.
  • To assess the realism and construct validity of the synthetic vessel model.

Main Methods:

  • A three-layered synthetic vessel was co-designed with a simulation company.
  • Microsurgical experts performed anastomoses on the synthetic vessel.
  • Realism was evaluated through user questionnaires; construct validity was assessed using objective task scores.

Main Results:

  • The synthetic vessel's intima and media demonstrated good realism; the adventitia requires improvement.
  • Objective assessments successfully identified expert performance levels.
  • The model showed promise as an intermediate-level training tool.

Conclusions:

  • The developed three-layered synthetic vessel serves as a hygienic and effective intermediate training model.
  • This model presents a viable alternative to existing synthetic and ex vivo training methods.
