“…al. (63) described the low-level laser-assisted liposuction, known as the Neira 4L technique. This technique, according to the authors, facilitates the liposuction procedure, in view of the results described on last study (25) , moderates the inflammatory response, reduces trauma to tissues and promotes subcutaneous wound healing after lipoplasty-assisted liposuction.…”

The aim of this study consisted in evaluating the influence of low power laser on the morfometry of white adipose cells in rats. The sample consisted of 20 adult female rats, from Wistar strain, randomized in four groups. All groups were submitted to tricotomy of the dorsal thoracic area and the first three groups were exposed to a InGaAlP laser (660 nm wavelength) with fluencies of 2, 8 and 16 J/cm 2 for groups L1, L2 and L3, respectively. L4 was the control. The groups were submitted to the protocols three times a week, for three weeks. The irradiated tissue was excised and submitted to histological treatment by HE for optical microscopy and the Kruskal-Wallis test was used for the statistical analysis. The average morphometry, in number of pixels, was: 3741 ± 704, 3762 ±947, 3737 ±1076 and 4619 ±781 for L1, L2, L3 and L4, respectively. There was no significant difference among groups L1 to L3 for the variable tested. From these results, it can be concluded that the application of low power laser -under the conditions proposed and for the fluency values chosen -influence the morphometry of white adipose cells in rats in the same manner, producing similar results.

“…26 In addition, cytochrome C oxidase activation results in the transient formation of pores in the cell membrane of adipocytes. 41 This allows the newly formed fatty acids and glycerol to pass through the membrane into the extracellular space. 27 Following 4 min of laser exposure, 80% of intracellular fat was released from adipose cells increasing to almost 100% after 6 min of exposure, 28 resulting in the complete collapse, but not death, of treated adipocytes.…”

Objective: To assess the effectiveness of low-level laser therapy (LLLT) for reducing hip, thigh, and abdomen circumference of individuals with body-mass index (BMI) between 30 and 40 kg/m 2. Background: Previous studies demonstrated the effectiveness of LLLT for reducing body circumference in the hips, thighs, and abdomen of nonobese individuals with a BMI <30 kg/m 2. Methods: In this randomized, double-blind shamcontrolled study, obese, but otherwise healthy, individuals were randomized to undergo 30-min LLLT (n = 28) or sham treatments (n = 25) three times weekly for 4 weeks. Body measurements were obtained after 2 and 4 weeks of treatment and 2 weeks post-treatment (ClinicalTrials.gov Identifier: NCT01821352). Results: After 4 weeks, 20 LLLT-treated subjects (71.43%) achieved ‡7.2 cm decrease in combined measurements versus three sham-treated subjects (12%; p < 0.00005). The mean (standard deviation) decrease in combined measurement for LLLT-treated subjects was 10.52 (7.59) cm (p < 0.0001 vs. baseline) versus 1.80 (3.20) cm for sham-treated subjects. Among subjects with a combined ‡7.2 cm decrease, the mean total decrease 2 weeks post-treatment was 15.21 cm. There were no adverse events. Conclusions: Based on these results, the device was cleared by the U.S. Food and Drug Administration as a noninvasive esthetic treatment for reduction of circumference of hips, waist, and upper abdomen when applied to individuals with a BMI between 30 and 40 kg/m 2 .

“…To date, the most studied low‐level laser treatment for non‐invasive body contouring uses a monochromatic 635 nm wavelength with an estimated output dosage of 1.0 J/cm 2 2–19. Studies have delineated these specific output parameters—when applied to adipocytes—activate intracellular secondary cascades causing the formation of transitory pores, or transmembrane openings, within the adipocyte membrane 2–9. Newly formed pores increase membrane permeability and engender the release of stored intracellular lipids—primarily as triglycerides 2–9.…”

This article presents the results of a study of infant diet at two Iron Age sites on the island of Öland, Sweden. The cemetery at Bjärby contained a large number of subadults who had survived the earliest years of life, whereas most individuals at Triberga had died by 6 months of age. To investigate whether differences in infant feeding could explain the different mortality rates, the carbon, nitrogen, and sulfur stable isotope ratios of bone and tooth dentin collagen from the two sites were analyzed. Twenty‐two samples from Triberga and 102 from Bjärby yielded data that could be included in the carbon and nitrogen analysis. Twelve samples from Triberga and 42 from Bjärby were included in the sulfur analysis. The results for carbon (δ13C: Triberga X = –18.8, s.d. = 1.1; Bjärby X = –19.8, s.d. = 0.4), nitrogen (δ15N: Triberga X = 12.9, s.d. = 1.5; Bjärby X = 13.4, s.d. = 1.4), and sulfur (δ34S: Triberga X = 8.1, s.d. = 1.1; Bjärby X = 5.8, s.d. = 1.3) suggest that diet was broadly similar at both sites and based on terrestrial resources. At Bjärby, females and high‐status individuals consumed higher‐trophic level protein than other males from early childhood onward. There was some indication that the contribution of marine resources to the diet may also have differed between the sexes at Triberga. No consistent differences in breast milk intake were observed between the two sites, but there was substantial variation at each. This variation may reflect an influence of gender and social status on infant feeding decisions. Am J Phys Anthropol 149:217–230, 2012. © 2012 Wiley Periodicals, Inc.
