Clinical Applications of Epidermal Stem Cells

Clinical Applications of Epidermal Stem Cells

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...

Water and Mineral Acquisition

Water and Mineral Acquisition

Specialized tissues in plant roots have evolved to capture water, minerals, and some ions from the soil. Roots exhibit a variety of branching patterns that facilitate this process. The outermost root cells have specialized structures called root hairs that increase the root surface, thus increasing soil contact. Water can passively cross into roots, as the concentration of water in the soil is higher than that of the root tissue. Minerals, in contrast, are actively transported into root cells.

Extracorporeal Removal of Drugs: Continuous Renal Replacement Therapy

Extracorporeal Removal of Drugs: Continuous Renal Replacement Therapy

Continuous Renal Replacement Therapy (CRRT) is an essential intervention for patients experiencing severe kidney dysfunction. This therapy offers a continuous mechanism for removing fluids and toxins from the bloodstream, leveraging the patient’s blood pressure to facilitate filtration through a specialized filter. This method contrasts with intermittent dialysis, providing a gentler and more consistent removal of waste products and excess fluid, which is particularly beneficial in...

Background:

External apical root resorption (EARR) is a common side effect of orthodontic treatment.
Comparing EARR between different orthodontic appliance systems is crucial for patient outcomes.

Purpose of the Study:

To compare the degree of external apical root resorption (EARR) in patients treated with Damon self-ligating appliances versus conventional preadjusted appliances.

Main Methods:

A sample of 52 patients was divided into two groups: Damon self-ligating (n=25) and conventional preadjusted (n=27).
Groups were matched for age, treatment duration, malocclusion type, and non-extraction protocol.
Root resorption was assessed using periapical radiographs and the Levander and Malmgren scoring system.

Main Results:

No statistically significant difference in the degree of EARR was observed between the Damon self-ligating and conventional preadjusted appliance groups.

Conclusions:

Similar degrees of external apical root resorption can be anticipated following non-extraction orthodontic treatment with either Damon self-ligating or conventional preadjusted appliances.
