Efficacy of Endolift laser for arm and under abdomen fat reduction

BACKGROUND

Noninvasive laser for body fat contouring is a quickly growing field in the cosmetic dermatology. Surgical options carry disadvantages, such as the usage of anesthetics, swelling, pain and long time for recovery, so there is a growing public request for the techniques with fewer side effects and shorter recovery periods. Several new noninvasive body contouring ways have been advanced such as, cryolipolysis radiofrequency energy, suction-massage, high-frequency focused ultrasound, and laser therapy. Noninvasive laser improves the body's appearance by the elimination of excess adipose tissue, specifically in areas in which fat perseveres in spite of diet and exercise.

METHODS

In this study the efficacy of Endolift laser was evaluated for reduction of excess fat in the arms and under abdomen. Ten patients with excess fat in the arms and under abdomen were enrolled in this study. The patients were treated by Endolift laser in the arms and under abdomen areas. The outcomes were evaluated by two blinded board certified dermatologists and by patients' satisfaction. The circumference of each arm and under abdomen was measured using a flexible tape measure.

RESULTS

The results showed reduction in the fat and circumference of arms and under abdomen after treatment. The treatment was considered as effective methods with high patient satisfaction. Also no severe adverse effects were reported.

CONCLUSION

Endolift laser can be a good alternative to surgical body fat contouring due to its efficacy, safety, minimal recovery time, low cost. Also Endolift laser does not require general anesthetics.

Application of vibration response technique for the firmness evaluation of pear fruit during storage

Storage conditions of pear affect its subsequent softening process and shelf life. Measurements of firmness have traditionally been carried out according to the Magness Taylor (MT) procedure; using a texture analyzer or penetrometer in reference texture tests. In this study, a non-destructive method using Laser Doppler vibrometer (LDV) technology was used to estimate texture firmness of pears. This technique was employed to detect responses to imposed vibration of intact fruit using a shaker. Vibration transmitted through the fruit to the upper surface was measured by LDV. A fast Fourier transform algorithm was used to process response signals and the desired results were extracted. Multiple Linear Regression models using fruit density and four parameters obtained from modal tests showed better correlation (R(2) = 0.803) with maximum force in Magness Taylor test compared to the models that used only modal parameters (R(2) = 0.798). The best polynomial regression models for pear firmness were based on elasticity index (EI) and damping ratio (η) with R(2) = 0.71 and R(2) = 0.64, respectively. This study shows the capability of the LDV technique and the vibration response data for predicting ripeness and modeling pear firmness and the significant advantage for commercially classifying of pears based on consumer demands.
