BACKGROUND: Plastic surgeons increasingly use social media to market their practices and educate prospective patients. Previous studies have investigated plastic surgery content on Instagram from the angle of hashtags and most popular plastic surgeons. However, very little is understood about what plastic surgeons themselves post on Instagram and what plastic surgery content average users engage with.
OBJECTIVE: The aim of this study was to analyze Instagram posts from accounts related to plastic surgeons in the USA to establish suggestions for growing one\'s practice with this powerful platform to reach patients.
METHODS: Board-certified plastic surgeons from all US regions that were active from February 1, 2023 to April 12, 2023 were randomly chosen. Their Instagram accounts were accessed for post analysis. For procedural posts, engagement statistics and multiple variables were collected. Dixon\'s outlier test was used to determine outliers in the data. ANCOVA and Tukey analysis was used to determine whether procedure type influenced engagement.
RESULTS: 120 surgeon accounts were identified with 2157 posts analyzed, yielding notable differences in posts among regions. Most posts were aesthetic procedures (94.4%) and of female patients (90.3%). Surgical procedures were also predominant (86.1%). In addition, Reels had higher engagement than photograph posts. Users engaged with Body procedures at the highest rate.
CONCLUSIONS: This cross-sectional analysis shows plastic surgeons tend to overwhelmingly post female patients, aesthetic procedures, and surgical content. These insights may be used to guide social media content and improve the effectiveness of Instagram as a tool for marketing or education.

BACKGROUND: The lips are one crucial determinant of facial attractiveness. Current studies investigating lip attractiveness were mostly conducted in Caucasians, and the results could not directly apply to Asians. Aside from lip proportions, lip contours play an important role in attractiveness but it is unclear how people perceive different lip contours. The aim of this study was to investigate the aesthetic perception of various lip shapes by Chinese to identify the most attractive lip morphology for women and men, respectively.
METHODS: 303 Chinese participants were invited to rate the attractiveness of identical lip images with different contours and proportions in a young female and a young male. Stratified analyses were performed to assess the effect of gender, age and occupation on the preference of lip shapes.
RESULTS: The lips that were rated to be most attractive had a flat upper vermilion border, an M-shaped oral fissure and a U-shaped lower vermilion border in both genders. Most respondents considered an upper-to-lower vermilion proportion of 1:1 to be more attractive, regardless of the gender of the lip models, and the lip thickness-to-width proportions of 1:2 and 1:2.5 were perceived most attractive for female and male, respectively.
CONCLUSIONS: This study adds to our understanding of how lip contours contribute to attractiveness and that Chinese have distinctive aesthetic preferences for lip morphology, which possibly stem from racial characteristics and cultural differences. With such knowledge, practitioners may better tailor the treatment strategy when performing lip rejuvenation procedures.

Professional tooth whitening in the dental office is a popular cosmetic procedure and is performed under carefully monitored conditions. This allows the controlled application of a relatively high concentration of bleaching ingredients based on hydrogen peroxide or peroxide derivatives which produce reactive oxygen species, and consequently induce enamel erosion, alteration of the microhardness of the teeth, irritation of the gums, pain or post bleach sensitivity. This short communication describes the successful and reliable application of a new professional tooth whitening technique using a novel phthalimido peroxycaproic acid complex while avoiding reactive oxygen species.

BACKGROUND: Using anaesthetics is an important application in aquaculture especially where the fish transportation, vaccination, grading, sorting activities and many other handling operations have been conducted during the different stages of production periods in the farms or hatcheries.
OBJECTIVE: This study aimed to evaluate the efficacy of oregano essential oil (OO) as an anaesthetic for Nile tilapia and to determine the optimal concentration and post-application stress effects compared to clove oil (CO).
METHODS: Nile tilapia juveniles were exposed to different concentrations of OO (20-40-60-80-100 mg L-1) and CO (50 mg L-1) for different time periods to determine the optimal concentration and exposure time. After the effective concentration of OO was determined, in the second experiment, stress parameters (glucose, plasma cortisol) were analysed after 0, 2, 6, 12 and 24 h of application. The results compared to the control group and CO results.
RESULTS: The study found that OO which has carvacrol compound higher than 78% was an efficient anaesthetic for Nile tilapia, and the effective concentration was found to be 60 mg L-1. No significant differences were found between opercular beats in any concentration of OO and CO. Basal glucose level in blood without anaesthesia application and recorded at 39.33 mg dL-1 and significantly lower than OO and CO at first two sampling points, 0 and 2 h (p < 0.05). According to plasma cortisol level results, although CO experimental group showed secondary stress response at 12 h (17.91 ± 4.21 ng mL-1), OO and CO group cortisol levels decreased at 24 h after anaesthesia application 7.13 ± 0.14and 7.01 ± 0.54 ng mL-1, respectively, below the control group cortisol concentration (12.28 ± 1.81 ng mL-1).
CONCLUSIONS: These findings have important implications for the aquaculture industry as the use of OO as an anaesthetic could reduce the stress and mortality associated with traditional anaesthetics. Further research is needed to evaluate the efficacy of OO as an anaesthetic agent for other fish species and to determine the optimal concentration and exposure time for different species.

Black-handed spider monkeys (Ateles geoffroyi ssp.) are endangered in Mexico. Safe anesthetic protocols are important for in situ and ex situ conservation problems. Such protocols are scarce in the literature; nor have safety and physiologic responses been reported. High doses and volume are a counter side for field immobilizations. We tested an anesthetic protocol with a combination of tiletamine-zolazepam (5 mg/kg) plus xylazine (1 mg/kg) in 14 black-handed spider monkeys under human care from two facilities in Mexico. Physiological parameters such as HR, RR, T, SPO2, systolic arterial pressure (), diastolic arterial pressure (DAP), and median arterial pressure (MAP) were obtained. HR and RR decreased over time, but T increased significantly during the anesthetic time for the whole group; RR and T decreased for juveniles only. Variation between individuals was observed for HR, RR, and DAP. Volume reduction of drugs was achieved compared to previously reported anesthesia protocols. Induction time was fast (6.2 ± 10.4 min) and no tail prehension was seen. Recovery was prolonged (mean and SD). Physiologic parameters remained stable throughout. The protocol proved to be safe for the chemical immobilization of black-handed spider monkeys.

To assess the evidence for the effect of strength and conditioning on physical qualities and aesthetic competence in dance populations, three electronic databases (PubMed, Scopus, SPORTDiscus) were searched (until September 2022) for studies that met the following criteria: (i) dancers aged >16 years; (ii) structured strength and conditioning intervention; and (iii) with physical qualities and aesthetic competence as outcome measures. Methodological quality and risk of bias of the included studies were assessed through the systematic review tool \"QualSyst\". Meta-analyses of effect sizes (Hedges\' g) with forest plots explored the effects of the strength and conditioning interventions. Thirty-six studies met the inclusion criteria and were included in this review. Meta-analysis indicated strength and conditioning significantly (p < 0.05) improved lower body power (g = 0.90, 95% CI: 0.53-1.27), upper body strength (g = 0.98, 95% CI: 0.39-1.57), lower body strength (g = 1.59, 95% CI: 0.97-2.22), and flexibility (g = 0.86, 95% CI: 0.05-1.66). Strength and conditioning interventions were found to be effective at improving physical qualities in dancers, recommending their participation in additional sessions to enhance overall fitness and ultimately dance performance. It is recommended that future strength and conditioning intervention research should include sample size calculations, with participants recruited from a specific dance genre and skill level in order to evaluate how strength and conditioning influences dance performance.

BACKGROUND: Gingival recession can be considered an undesirable condition that results in the exposure of the root surface. There are many techniques that can be employed to address gingival recession; however, they frequently involve a second surgical site. Other approaches have been introduced in the past to address this concern, and this case study discusses the use of a modified technique to achieve root coverage.
METHODS: A patient presented to the periodontics clinic with concerns regarding gingival recession. A modification to the semilunar technique was employed to address the recession, whereas double sling sutures were utilized to maintain the coronal repositioning of the flap.
RESULTS: Maxillary central incisors initially presented with 2-3 mm of facial recession and root coverage was achieved by use of a modified surgical semilunar approach. No rebound noted over a 6-month period, newly established gingival margin deemed clinically stable.
CONCLUSIONS: This case study provides an alternative to addressing gingival recession in the maxillary anterior region, when <3 mm of recession is noted. Avoidance of a second surgical procedure and/or donor site is of particular benefit, as well as maintenance of the blood supply.
CONCLUSIONS: Why is this case new information? There is insufficient evidence on the use of a modified wingspan incision design Phenotype modification with elimination of a second surgical site is most ideal for the patient. What are the keys to successful management of this case? Comprehensive diagnosis and proper case selection Meticulous flap management and adequate release to allow for repositioning without tension Appropriate use ofsuture and suturing technique. What are the primary limitations to success in this case? Thin periodontal phenotype Poor oral hygiene and plaque accumulation postoperatively Loss to follow-up.

Within cognitive psychology, there are separate experimental fields devoted to the study of creativity, on the one hand, and aesthetics, on the other, with virtually no cross-talk between them. In this article, I propose a means of uniting creativity and aesthetics via a consideration of the mechanisms of cultural evolution. I call this the creativity/aesthetics cycle. The basic tenet of the model is that creativity and aesthetics mediate, respectively, the processes of variation (production) and selection (perception or consumption) in evolutionary models of culture. By means of this cycle, creators produce works that they hope will be evaluated positively by consumers, where such appraisals ultimately feed back to influence the subsequent decision-making processes of creators. I discuss the implications of this model for the fields of creativity and aesthetics.

BACKGROUND: Quantitative evaluation of facial aesthetics is an important but also time-consuming procedure in orthognathic surgery, while existing 2D beauty-scoring models are mainly used for entertainment with less clinical impact.
METHODS: A deep-learning-based 3D evaluation model DeepBeauty3D was designed and trained using 133 patients\' CT images. The customised image preprocessing module extracted the skeleton, soft tissue, and personal physical information from raw DICOM data, and the predicting network module employed 3-input-2-output convolution neural networks (CNN) to receive the aforementioned data and output aesthetic scores automatically.
RESULTS: Experiment results showed that this model predicted the skeleton and soft tissue score with 0.231 ± 0.218 (4.62%) and 0.100 ± 0.344 (2.00%) accuracy in 11.203 ± 2.824 s from raw CT images.
CONCLUSIONS: This study provided an end-to-end solution using real clinical data based on 3D CNN to quantitatively evaluate facial aesthetics by considering three anatomical factors simultaneously, showing promising potential in reducing workload and bridging the surgeon-patient aesthetics perspective gap.
