Clinical Applications of Epidermal Stem Cells01:19

Clinical Applications of Epidermal Stem Cells

3.3K
Epidermal stem cells (EpiSCs) are mainly located at the basal layer of the epidermis. These cells repair minor injuries of the skin and replace dead skin cells. However, EpiSCs’ cannot heal severe wounds such as major burns or those from diabetes or hereditary disorders. In such cases, culturing the epidermal stem cells from the patient is possible and has yielded successful treatment options, such as laboratory-grown skin grafts. These grafts are synthesized using a patient’s own...

Psychology as a Science

4.0K
Psychology, as a scientific discipline, aims to understand the mind and behavior through rigorous and systematic methods. The foundation of psychological research is evidence-based, relying heavily on the scientific method to derive and validate knowledge. This structured approach ensures that findings are reliable, valid, and applicable to broader contexts.
The scientific method in psychology involves six critical steps: making observations, formulating hypotheses, conducting tests, analyzing...

Local Anesthetics: Clinical Application as Spinal Anesthesia01:11

Local Anesthetics: Clinical Application as Spinal Anesthesia

1.5K
Spinal anesthetics are given during lower abdomen and limb surgeries to block sensory and motor neurons. They are administered in the mid to low lumbar regions, primarily acting on the cauda equina's nerve roots. The blockade level depends on the local anesthetic (LA) concentration. Usually, low LA concentrations are sufficient to block sensory fibers, while only high LA concentrations block motor fibers. Other factors like injection volume and speed, the patient's posture, and the drug...

Local Anesthetics: Clinical Application as Epidural Anesthesia

777
Epidural anesthetics are administered in the fat-filled epidural space, the outermost part of the spinal canal. This technique is commonly employed for pain management and anesthesia during lower abdomen and pelvis surgeries or labor and delivery.
Since epidural anesthetics can be infused through an epidural catheter, all types of drugs, including short-acting ones, can be administered. Chloroprocaine and lidocaine are examples of short and long-duration anesthetics, respectively. Bupivacaine...

Overview of Biostatistics in Health Sciences

5.3K
Biostatistics involves the application of statistical techniques to scientific research in health-related fields, including biology and public health. These techniques are essential for designing studies, collecting data, and analyzing it to draw meaningful conclusions. Given the complexity of biological processes, particularly in studies involving human subjects, biostatistical methods are crucial for effectively organizing and interpreting data that might otherwise obscure underlying patterns...

Area of Science:

  • Biomaterials Science
  • Regenerative Medicine
  • Cardiovascular Research

Background:

  • Valvular heart disease is a growing health concern, particularly in the elderly, leading to significant morbidity and mortality.
  • Current heart valve replacement options (mechanical, bioprosthetic) have limitations and often require reoperation.
  • There is a critical need for durable, lifelong heart valve solutions due to increasing life expectancy.

Purpose of the Study:

  • To review advances in tissue-engineered heart valves (TEHVs).
  • To outline the design, validation, and clinical translation pathway for novel TEHVs.
  • To discuss the potential and challenges of TEHVs in clinical application.

Main Methods:

  • In-silico and in-vitro models for assessing valve design, function, and compatibility.
  • In-vivo preclinical models to evaluate remodeling and growth potential of TEHVs.
  • Review of existing literature on TEHV studies, including those reaching clinical trials.

Main Results:

  • TEHVs offer a promising regenerative approach to overcome limitations of current valve prostheses.
  • A structured pathway involving in-silico, in-vitro, and in-vivo models is essential for TEHV development.
  • Several TEHV studies have progressed towards clinical translation, demonstrating feasibility.

Conclusions:

  • Tissue engineering holds significant potential for creating self-repairing, durable heart valves.
  • Overcoming translational obstacles is key to widespread clinical application of TEHVs.
