Reconstruction of Signal using Interpolation

Reconstruction of Signal using Interpolation

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...

Electron Microscope Tomography and Single-particle Reconstruction

Electron Microscope Tomography and Single-particle Reconstruction

Transmission electron microscopy (TEM) can be used to determine the 3D structure of biological samples with the help of techniques such as electron microscope tomography and single-particle reconstruction. While single-particle reconstruction can examine macromolecules and macromolecular complexes in vitro conditions only, tomography permits the study of cell components or small cells in vivo.
Electron Tomography
Electron tomography can be performed either in TEM or STEM (scanning transmission...

Tissues

Tissues

Cells with similar structure and function are grouped into tissues. A group of tissues with a specialized function is called an organ. There are four main types of tissue in vertebrates: epithelial, connective, muscle, and nervous.

Tissues

Tissues

Tissues are a group of cells that share a common embryonic origin. Microscopic observation reveals that the cells in a tissue share morphological features and are arranged in an orderly pattern to perform specific functions. From an evolutionary perspective, tissues appear in more complex organisms. Although there are many types of cells in the human body, they are organized into four broad categories of tissues: epithelial, connective, muscle, and nervous. Each of these categories is...

Plant Cells and Tissues

Plant Cells and Tissues

Plant tissues are collections of similar cells performing related functions. Different plant tissues will have their own specialized roles and can be combined with other tissues to form organs such as flowers, fruit, stem, and leaves. Two major types of plant tissue include meristematic and permanent tissue.

Plant Tissue Culture

Plant Tissue Culture

Plant tissue culture is widely used in both primary and applied science. Applications range from plant development studies to functional gene studies, crop improvement, commercial micropropagation, virus elimination, and conservation of rare species.

Area of Science:

Biomaterials Science
Regenerative Medicine
Tissue Engineering

Background:

Autologous fat grafting is standard for soft tissue reconstruction but faces limitations like graft resorption and donor site morbidity.
Developing injectable scaffolds is key to overcoming these limitations for larger volume reconstructions.
Current scaffolds aim to mimic native adipose tissue's biological, structural, and mechanical properties.

Purpose of the Study:

To review current injectable scaffolds for soft tissue volume restoration.
To emphasize their translational potential and future directions in adipose tissue engineering.
To address challenges in creating reliable soft tissue substitutes for large-volume reconstruction.

Main Methods:

Review of natural, synthetic, and adipose extracellular matrix (aECM)-derived injectable scaffolds.
Analysis of scaffold properties including biocompatibility, mechanical strength, degradation rates, and bioactivity.
Evaluation of scaffolds for their potential to promote adipogenesis and angiogenesis.

Main Results:

Natural scaffolds offer biocompatibility but have rapid degradation and poor mechanical strength.
Synthetic scaffolds provide tunable properties but need biofunctionalization for cell integration.
aECM-derived scaffolds combine biomimicry with biological cues, offering a promising
off-the-shelf
solution.

Conclusions:

Injectable scaffolds are advancing soft tissue reconstruction, offering alternatives to autologous fat grafting.
aECM-derived scaffolds represent a significant step towards clinically viable, large-volume soft tissue substitutes.
Challenges remain in developing reliable, long-lasting soft tissue substitutes for extensive reconstruction needs.
