Gene Therapy00:59

Gene Therapy

27.7K
Gene therapy is a technique where a gene is inserted into a person’s cells to prevent or treat a serious disease. The added gene may be a healthy version of the gene that is mutated in the patient, or it could be a different gene that inactivates or compensates for the patient’s disease-causing gene. For example, in patients with severe combined immunodeficiency (SCID) due to a mutation in the gene for the enzyme adenosine deaminase, a functioning version of the gene can be...

Light Acquisition02:16

Light Acquisition

9.6K
In order to produce glucose, plants need to capture sufficient light energy. Many modern plants have evolved leaves specialized for light acquisition. Leaves can be only millimeters in width or tens of meters wide, depending on the environment. Due to competition for sunlight, evolution has driven the evolution of increasingly larger leaves and taller plants, to avoid shading by their neighbors with contaminant elaboration of root architecture and mechanisms to transport water and nutrients.

Light as Energy

96.3K
The energy required to carry out photosynthesis is light— typically electromagnetic radiation from the sun. The range of all possible wavelengths is known as the electromagnetic spectrum.
Photons
A photon is a discrete electromagnetic particle or bundle of energy. Photons are characterized by their frequency, wavelength, and amplitude, similar to the properties of a wave. Waves with higher frequencies transmit more energy and have shorter wavelengths than longer wavelengths that transmit...

Group Therapy01:26

Group Therapy

460
Group therapy is a sociocultural approach to psychological treatment, where individuals with shared psychological challenges come together under the guidance of a mental health professional. This therapeutic modality offers unique opportunities for individuals to connect, share, and grow within the context of a supportive group. By fostering mutual understanding and collaboration, group therapy can address a range of psychological concerns effectively, often complementing or surpassing the...

The Wave Nature of Light02:12

The Wave Nature of Light

61.6K
The nature of light has been a subject of inquiry since antiquity. In the seventeenth century, Isaac Newton performed experiments with lenses and prisms and was able to demonstrate that white light consists of the individual colors of the rainbow combined together. Newton explained his optics findings in terms of a "corpuscular" view of light, in which light was composed of streams of extremely tiny particles traveling at high speeds according to Newton's laws of motion.

Photoreceptors and Plant Responses to Light02:00

Photoreceptors and Plant Responses to Light

28.6K
Light plays a significant role in regulating the growth and development of plants. In addition to providing energy for photosynthesis, light provides other important cues to regulate a range of developmental and physiological responses in plants.

Summary
This summary is machine-generated.

Evidence for light therapies in acne treatment is weak. Red-light methyl aminolevulinate-photodynamic therapy (MAL-PDT) showed minimal, clinically insignificant improvements for acne, with uncertain safety due to inadequate adverse effect reporting.

Area of Science:

  • Dermatology
  • Photomedicine

Background:

  • Acne vulgaris is a common skin condition.
  • Light therapies are explored as treatment options for acne.

Purpose of the Study:

  • To evaluate the effectiveness and safety of various light therapies for acne treatment.

Main Methods:

  • Review of existing evidence on light therapies for acne.
  • Analysis of treatment outcomes and adverse events.

Main Results:

  • Overall evidence for light therapies in acne is weak and inconclusive.
  • Red-light methyl aminolevulinate-photodynamic therapy (MAL-PDT) demonstrated a small, clinically insignificant reduction in inflamed acne lesions.
  • No significant increase in severe adverse effects for red-light MAL-PDT compared to placebo.

Conclusions:

  • Current evidence does not strongly support the efficacy of light therapies for acne.
  • The safety of light therapies for acne remains uncertain due to insufficient reporting of adverse effects like scarring or blistering.
