Reconstruction of Signal using Interpolation01:10

Reconstruction of Signal using Interpolation

704
Signal processing techniques are essential for accurately converting continuous signals to digital formats and vice versa. When a continuous signal is sampled with a period T, the resulting sampled signal exhibits replicas of the original spectrum in the frequency domain, spaced at intervals equal to the sampling frequency. To handle this sampled signal, a zero-order hold method can be applied, which creates a piecewise constant signal by retaining each sample's value until the next...

Skin Cancer01:30

Skin Cancer

5.8K
Skin cancer is a type of cancer that occurs when there is an abnormal growth of skin cells, usually triggered by damage to the DNA within the skin cells. It is primarily caused by exposure to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. Skin cancer is the most common type of cancer worldwide, and its incidence continues to rise.
Basal Cell Carcinoma (BCC): BCC is the most common type of skin cancer, accounting for about 80% of cases. It typically develops in...

Sensory Functions of the Skin01:16

Sensory Functions of the Skin

8.0K
The skin is the largest organ of the human body and plays a crucial role in our sensory perception. It contains a vast network of sensory receptors that contribute to the skin's protective function by perceiving physical, biological, and environmental cues and generating relevant responses.
There are two main categories of receptors on the skin: capsulated and non-capsulated. The non-capsulated ones are mainly the pain receptors. The capsulated ones can be further categorized based on the...

Skin Diseases and Disorders01:23

Skin Diseases and Disorders

5.2K
Skin is the first line of defense and encounters a variety of microbes. Some pathogenic strains are often the cause of a broad range of infections of the skin and other body systems. These conditions can affect people of all ages and may have different causes, including genetic factors, infections, autoimmune reactions, environmental factors, and lifestyle choices.
Gram-positive Staphylococcus spp. and Streptococcus spp. are responsible for many of the most common skin infections. However, many...

Mouse Models of Cancer Study02:43

Mouse Models of Cancer Study

6.4K
Mice have long served as models for studying human biology and pathology because of their phylogenetic and physiological similarity with humans. They are also easy to maintain and breed in the laboratory, and hence, many inbred strains are now available for research. Studies on mice have contributed immeasurably to our understanding of cancer biology.
The development of transgenic, knockout, and knock-in mice has led to an exponential increase in their use as model organisms in research,...

Role of Skin in Vitamin D Synthesis01:23

Role of Skin in Vitamin D Synthesis

7.6K
The skin plays a crucial role in the synthesis of vitamin D, a vital nutrient for various physiological processes in the body. Vitamin D is unique because it can be synthesized in the skin through a series of chemical reactions triggered by exposure to ultraviolet B (UVB) radiation from sunlight.
The solar UV B rays (290-315 nm) are absorbed by the skin, and 7-dehydrocholesterol (provitamin D3) photolyzes it to previtamin D3, which undergoes a rapid transformation to vitamin...

Area of Science:

  • Regenerative Medicine
  • Dermatology
  • Tissue Engineering

Background:

  • Existing in vivo skin models fail to precisely mimic native human skin.
  • There is a need for advanced laboratory and clinical skin models.

Purpose of the Study:

  • To develop a novel in vivo human skin model (hRSK) using culture-expanded skin cells.
  • To create a model that accurately recapitulates the structure and appendages of native human skin.

Main Methods:

  • Dissociated human epidermal and dermal cells were cultured.
  • A mixture of these cells was grafted onto an excision wound in immunodeficient mice.
  • The reconstituted tissue was analyzed histologically.

Main Results:

  • The generated human skin model (hRSK) successfully reconstituted epidermis, dermis, and subcutis.
  • Appendages such as hair follicles were observed within the hRSK.
  • Histological analysis confirmed that hRSK mirrors in situ human skin.

Conclusions:

  • The described method enables in vivo reconstitution of a human skin model (hRSK).
  • The hRSK serves as a viable in vivo model that histologically mirrors native human skin.
  • This model holds potential for future laboratory and clinical applications in skin research.
