Pulse01:16

Pulse

2.1K
When the heart pumps blood out, arterial elastic fibers play a crucial role in sustaining a high-pressure gradient. They expand to accommodate the received blood and then recoil - a process known as the pulse that can be either manually palpated or electronically quantified. Despite a reduction in its effect with increased distance from the heart, elements of the pulse's systolic and diastolic components persist, observable even at the arteriole level.
The pulse serves as a clinical...

Pulse01:05

Pulse

3.8K
The pulse is one of the most fundamental physiological indicators of the body's cardiovascular health. It is the rhythmic expansion and contraction of the arterial walls in response to the pressure generated by the heart's pumping action.
Pulse Rate and its Significance
Pulse rate, often measured in beats per minute (bpm), reflects the heart rate (HR), which is influenced by numerous factors such as stress, physical activity, and hormonal changes. A normal resting adult pulse rate falls...

Sound Intensity00:58

Sound Intensity

4.8K
The loudness of a sound source is related to how energetically the source is vibrating, consequently making the molecules of the propagation medium vibrate. To measure the loudness of a source, the physical quantity of interest is the intensity. This is defined as the energy emitted per unit of time per unit of area perpendicular to the sound wave's propagation direction. Since the total energy is greater if the source vibrates for a longer duration and over a larger area, dividing the...

NMR Spectrometers: Radiofrequency Pulses and Pulse Sequences01:17

NMR Spectrometers: Radiofrequency Pulses and Pulse Sequences

1.8K
A pulse is a short burst of radio waves distributed over a range of frequencies that simultaneously excites all the nuclei in the sample. Upon passing a radio frequency pulse along the x-axis, the nuclei absorb energy corresponding to their Larmor frequencies and achieve resonance. This shifts the net magnetization vector from the z-axis toward the transverse plane. This angle of rotation of the magnetization vector, or the flip angle, is proportional to the duration and intensity of the pulse.

Pulse Oximetry01:24

Pulse Oximetry

1.4K
Pulse oximetry, or SpO2, is a non-invasive method for continuously monitoring arterial oxygen saturation (SaO2). This procedure involves attaching a probe or sensor to the patient's fingertip, forehead, earlobe, or nose bridge. The sensor works by detecting changes in oxygen saturation levels through light signals generated by the oximeter and reflected by the pulsing blood under the probe.
Purpose
Average SpO2 values are greater than 95%. If the readings fall below 90%, it indicates that...

Regulation of Pulse01:20

Regulation of Pulse

2.3K
Pulse regulation involves physiological mechanisms that ensure adequate blood flow throughout the body. The heartbeat, regulated by the autonomic nervous system, is influenced by hormonal balance, physical activity, and emotional state.

Summary

A new cream containing 4-tert-butylcyclohexanol, Tephrosia purpurea seed extract, and Schisandra sphenanthera extract (TTS cream) significantly improves skin recovery after intense pulsed light (IPL) therapy. The TTS cream effectively reduces redness and discomfort, enhancing skin barrier repair.

Area of Science:

  • Dermatology
  • Aesthetic Medicine
  • Cosmetic Science

Background:

  • Intense pulsed light (IPL) therapy is a popular skin rejuvenation treatment.
  • IPL therapy can cause temporary skin barrier impairment, redness, and discomfort.
  • Effective post-procedure skincare is crucial for skin recovery and symptom management.

Purpose of the Study:

  • To assess the efficacy and safety of a novel cream (TTS cream) for post-IPL skin recovery.
  • To evaluate the TTS cream's ability to repair the skin barrier and alleviate symptoms.
  • To determine patient satisfaction with the TTS cream after IPL treatment.

Main Methods:

  • A randomized, double-blind, split-face study was conducted on 30 healthy female subjects.
  • Subjects received IPL therapy, with TTS cream applied to one side of the face and a control toner to the other.
  • Objective and subjective assessments of skin condition and symptoms were performed at multiple time points.

Main Results:

  • IPL therapy increased transepidermal water loss (TEWL), erythema, and skin dehydration.
  • TTS cream significantly improved skin hydration within 30 minutes post-application compared to the control.
  • TTS cream significantly reduced erythema, erythema area, and TEWL by day 28, with high subject satisfaction and no reported adverse effects.

Conclusions:

  • The TTS cream demonstrates significant efficacy in enhancing skin barrier recovery after IPL therapy.
  • TTS cream effectively reduces erythema and alleviates post-procedure discomfort.
  • This TTS cream shows promise for use in postoperative care following aesthetic medicine procedures.
