The Role of the Ventromedial Prefrontal Cortex in Preferential Decisions for Own- and Other-Age Faces. Front Psychol 2022; 13:822234. [PMID: 35360573 PMCID: PMC8962742 DOI: 10.3389/fpsyg.2022.822234] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/25/2021] [Accepted: 02/16/2022] [Indexed: 11/21/2022] Open
Abstract
Own-age bias is a well-known bias reflecting the effects of age, and its role has been demonstrated, particularly, in face recognition. However, it remains unclear whether an own-age bias exists in facial impression formation. In the present study, we used three datasets from two published and one unpublished functional magnetic resonance imaging (fMRI) study that employed the same pleasantness rating task with fMRI scanning and preferential choice task after the fMRI to investigate whether healthy young and older participants showed own-age effects in face preference. Specifically, we employed a drift-diffusion model to elaborate the existence of own-age bias in the processes of preferential choice. The behavioral results showed higher rating scores and higher drift rate for young faces than for older faces, regardless of the ages of participants. We identified a young-age effect, but not an own-age effect. Neuroimaging results from aggregation analysis of the three datasets suggest a possibility that the ventromedial prefrontal cortex (vmPFC) was associated with evidence accumulation of own-age faces; however, no clear evidence was provided. Importantly, we found no age-related decline in the responsiveness of the vmPFC to subjective pleasantness of faces, and both young and older participants showed a contribution of the vmPFC to the parametric representation of the subjective value of face and functional coupling between the vmPFC and ventral visual area, which reflects face preference. These results suggest that the preferential choice of face is less susceptible to the own-age bias across the lifespan of individuals.

Abstract
Study Design Retrospective descriptive observational study. Purpose Skiing and snowboarding offers valuable opportunities for outdoor physical activity throughout the cold winter months, but these activities can result in substantial personally injury. This study aimed to analyze trends in skiing and snowboarding-related facial trauma epidemiology. Methods The National Electronic Injury Surveillance System (NEISS) was queried for facial trauma related to skiing and snowboarding treated in United States (US) emergency departments between 2010 and 2019. These data and weighted estimates were used to analyze patient demographics, injury location, and etiology. Results A total of 361 skiing or snowboarding-related facial injuries were recorded. Lacerations were most common injury (165/361; 45.7%), and facial fractures occurred in 21.6% (78/261) of patients. The most common facial fracture locations are the nose (38/78; 48.7%), orbit (17/78; 21.8%), and mandible (15/78; 19.2%). Pediatric patients accounted for 52% (187/361) of these injuries and had higher rates of lacerations (51.9% vs 39.1%, P < 0.05) and hospital admission (4.8% vs 1.15%, P < 0.05) than adults. Adults had a higher rate of facial fracture (30% vs 13.9%, P < 0.001) than children. Conclusions Skiing and snowboarding-related facial trauma is relatively uncommon in the US. In general, these injuries are largely decreasing, but facial fractures still occur not infrequently during these activities. Based on our data, we strongly urge helmet manufacturers to increase the availability of recreational snowsport helmets that include nose, orbit, and mandible protections, which could help to prevent many of these injuries.

Abstract
Parkinson’s disease (PD) is a neurological disorder that mainly affects the motor system. Among other symptoms, hypomimia is considered one of the clinical hallmarks of the disease. Despite its great impact on patients’ quality of life, it remains still under-investigated. The aim of this work is to provide a quantitative index for hypomimia that can distinguish pathological and healthy subjects and that can be used in the classification of emotions. A face tracking algorithm was implemented based on the Facial Action Coding System. A new easy-to-interpret metric (face mobility index, FMI) was defined considering distances between pairs of geometric features and a classification based on this metric was proposed. Comparison was also provided between healthy controls and PD patients. Results of the study suggest that this index can quantify the degree of impairment in PD and can be used in the classification of emotions. Statistically significant differences were observed for all emotions when distances were taken into account, and for happiness and anger when FMI was considered. The best classification results were obtained with Random Forest and kNN according to the AUC metric.

Abstract
Disgust represents a multifaceted defensive-avoidance response. On the behavioral level, the response includes withdrawal and a disgust-specific facial expression. While both serve the avoidance of pathogens, the latter additionally transmits social-communicative information. Given that common and distinct brain representation of the primary defensive-avoidance response (core disgust) and encoding of the social-communicative signal (social disgust) remain debated, we employed neuroimaging meta-analyses to (1) determine brain systems generally engaged in disgust processing, and (2) segregate common and distinct brain systems for core and social disgust. Disgust processing, in general, engaged a bilateral network encompassing the insula, amygdala, occipital and prefrontal regions. Core disgust evoked stronger reactivity in left-lateralized threat detection and defensive response network including amygdala, occipital and frontal regions, while social disgust engaged a right-lateralized superior temporal-frontal network engaged in social cognition. Anterior insula, inferior frontal and fusiform regions were commonly engaged during core and social disgust, suggesting a shared neurofunctional basis. We demonstrate a common and distinct neural basis of primary disgust responses and encoding of associated social-communicative signals.

Key AP, Jones D, Corbett BA. Sex differences in automatic emotion regulation in adolescents with autism spectrum disorder. Autism Res 2022; 15:712-728.

Abstract
Autism may be underdiagnosed in females because their social difficulties are often less noticeable. This study explored sex differences in automatic facial emotion processing in 45 adolescents with autism spectrum disorder (22 female, 23 male), age 10-16 years, performing active target detection task and Go/NoGo tasks where faces with positive and negative emotional expressions served as irrelevant distractors. The combined sample demonstrated more accurate performance on the target detection (response initiation) than the Go/NoGo task (response inhibition), replicating findings previously reported in typical participants. Females exhibited greater difficulty than males with response initiation in the target detection task, especially in the context of angry faces, while males found withholding a response in the Go/NoGo block with happy faces more challenging. Electrophysiological data revealed no sex differences or emotion discrimination effects during the early perceptual processing of faces indexed by the occipitotemporal N170. Autistic males demonstrated increased frontal N2 and parietal P3 amplitudes compared to females, suggesting greater neural resource allocation to automatic emotion regulation processes. The associations between standardized behavioral measures (autism severity, theory of mind skills) and brain responses also varied by sex: more adaptive social functioning was related to the speed of perceptual processing (N170 latency) in females and the extent of deliberate attention allocation (P3 amplitudes) in males. Together, these findings suggest that males and females with autism may rely on different strategies for social functioning and highlight the importance of considering sex differences in autism. LAY SUMMARY: Females with autism may exhibit less noticeable social difficulties than males. This study demonstrates that autistic females are more successful than males at inhibiting behavioral responses in emotional contexts, while males are more likely to initiate a response. At the neural level, social functioning in females is related to the speed of automatic perceptual processing of facial cues, and in males, to the extent of active attention allocation to the stimuli. These findings highlight the importance of considering sex differences in autism diagnosis and treatment selection.

Abstract
BACKGROUND AND OBJECTIVE Radiofrequency (RF) devices which are under ongoing technological development, are being increasingly used for minimally invasive rejuvenation procedures. The objective is to evaluate the efficacy and safety of a procedure that uses bipolar RF microneedles for rejuvenation of the lower face and neck. STUDY DESIGN AND METHODS A prospective clinical and histological study, with a blind evaluation of the results by independent evaluators. Twenty-four women over 40 years of age were evaluated, who were treated with bipolar RF equipment (Profound™; Candela Medical) during a single session. Biopsy samples were taken from 12 patients. Microscopy images related to the immediate effects of RF and the changes observed 4 months after treatment were examined. The clinical results were established through questionnaires and by comparing before and after photographs. Mean (m), range (R), and percentage (%) values were calculated. RESULTS Immediate lysis of adipocytes in submental fat was observed, as well as an increase in the density and compaction of elastin and collagen fibers 4 months later. The average percentage of reduction in fine lines, wrinkles, furrows, and folds was around 30%, while the average improvement of the neck silhouette was around 20%. Photographic signs of aging improved significantly, both in the face (p = 0.0007) and the neck (p = 0.002). Patient and therapist satisfaction with the results was 8.3/10 (R = 3-10) and 9.3/10 (R = 8-10), respectively. The adverse effects were mild and temporary and no complications were observed. CONCLUSION The procedure is safe, clinically effective, and satisfactory for patients.

Abstract
PURPOSE To compare orofacial anthropometric measurements, with weight, height and sex of newborns. METHODS Observational cross-sectional study carried out with 130 newborns on exclusive breastfeeding. Data collection was performed by properly trained and calibrated speech therapists. The orofacial measurements of the newborns were performed with flexible and transparent ruler 10 cm long, in the following segments: heights of the upper third(tr-g), the middle third(g-sn) and the lower third on the face (sn-gn); filter height (sn-Is), distance between the corner of the eye and the labial commissure on the right and left side (ex-ch). Weight and height measurements were collected from the newborns' medical records. The data were submitted to statistical analysis, using the Mann-Whitney test, adopting a significance level of 5%. RESULTS Of the 130 newborns, 61 were male and 69 female. The median weight was 3.3 kg and the median height was 49 cm. There was significant difference between weight and measurement distance between the corner of the eye and the left and right labial commissure (ex-ch). There was no significant difference in orofacial measurements with sex and height. CONCLUSION There was no difference in orofacial anthropometric measurements of full-term newborns when compared with sex and height; however, when compared to weight, there is a difference in the measurements of the distance between the corner of the eye and the labial commissure on the right and left side.

Abstract
N170 is a negative event-related potential (ERP) component in response to visual stimuli, such as faces. It remains controversial whether N170 reflects the specific processing of faces or can also be elicited by objects of expertise (e.g., words). In this research, we conducted a meta-analysis for the spatiotemporal characteristics of N170 of face and word stimuli from 24 studies in which both stimuli were presented for each subject. We observed that (1) both face and word stimuli can elicit conspicuous N170s and that there was no difference between the amplitude of face-N170 and word-N170; (2) there is no difference in the latencies between the two N170s; and (3) both N170s are distributed in the occipitotemporal regions but with a reversed hemispheric distribution pattern-face-N170 is more negative in the right than left occipitotemporal regions, while word-N170 is the opposite. These results showed that the face- and word-N170s are qualitatively the same but have different hemispheric lateralization advantages-N170 might be a general neural index of the expertise-dependent object-recognition process in occipitotemporal regions.

Abstract
INTRODUCTION Movement disorders have been suggested to be a cardinal component of schizophrenia. With increased research interests in this area, instrumental measures are needed. This study was to examine if the motion capture system was reliable in measuring hand and facial bradykinesia and dyskinesia and more sensitive to detecting movement differences between schizophrenia patients and healthy people than traditional rating scales. METHODS Sixteen schizophrenia patients and 20 control subjects were recruited. Hand and facial bradykinesia and dyskinesia were measured using the motion capture system and rated using the Extrapyramidal Symptom Rating Scale and the Abnormal Involuntary Movement Scale. RESULTS The system showed strong test-retest reliability and generated larger effect sizes of group differences than did the rating scales. CONCLUSIONS The results may support researchers and clinical practitioners to apply the system to sensitively measuring the hand and facial movement symptoms in schizophrenia patients, which contributes to gaining a deep understanding of movement issues in schizophrenia.

Abstract
Facial artery pseudoaneurysms are rare and mostly a result of blunt injury. Since the facial arteries are well protected by facial soft tissue and the lumen of the facial artery is thin and small in diameter, a sharp injury usually leads to complete transection rather than partial laceration of the blood vessel. As a non-invasive method, ultrasound does not involve radiation and sedation. Diagnosis of facial artery pseudoaneurysms is most commonly made with ultrasound, and Doppler ultrasound is essential. On grayscale imaging, facial artery pseudoaneurysms often appearanced of a fluid collection, Color Doppler imaging often show a well-defined swirl pattern named "yin and yang sign," the Spectral Doppler showed a diagnostic "to and fro" two-phase bidirectional arterial blood flow spectrum. It's particularly for the examination of facial artery pseudoaneurysms in children. Here, we report a case of facial foreign body abscess and facial artery pseudoaneurysm in a 19-month-old child 1 week after a sharpness injury that was diagnosed by ultrasound.

Abstract
The human amygdala and hippocampus are critically involved in various processes in face perception. However, it remains unclear how task demands or evaluative contexts modulate processes underlying face perception. In this study, we employed two task instructions when participants viewed the same faces and recorded single-neuron activity from the human amygdala and hippocampus. We comprehensively analyzed task modulation for three key aspects of face processing and we found that neurons in the amygdala and hippocampus (1) encoded high-level social traits such as perceived facial trustworthiness and dominance and this response was modulated by task instructions; (2) encoded low-level facial features and demonstrated region-based feature coding, which was not modulated by task instructions; and (3) encoded fixations on salient face parts such as the eyes and mouth, which was not modulated by task instructions. Together, our results provide a comprehensive survey of task modulation of neural processes underlying face perception at the single-neuron level in the human amygdala and hippocampus.

Abstract
State anxiety appears to influence facial emotion processing (Attwood et al. 2017 R. Soc. Open Sci. 4, 160855). We aimed to (i) replicate these findings and (ii) investigate the role of trait anxiety, in an experiment with healthy UK participants (N = 48, 50% male, 50% high trait anxiety). High and low state anxiety were induced via inhalations of 7.5% carbon dioxide enriched air and medical air, respectively. High state anxiety reduced global emotion recognition accuracy (p = 0.01, η p 2 = 0.14 ), but it did not affect interpretation bias towards perceiving anger in ambiguous angry-happy facial morphs (p = 0.18, η p 2 = 0.04 ). We found no clear evidence of a relationship between trait anxiety and global emotion recognition accuracy (p = 0.60, η p 2 = 0.01 ) or interpretation bias towards perceiving anger (p = 0.83, η p 2 = 0.01 ). However, there was greater interpretation bias towards perceiving anger (i.e. away from happiness) during heightened state anxiety, among individuals with high trait anxiety (p = 0.03, d z = 0.33). State anxiety appears to impair emotion recognition accuracy, and among individuals with high trait anxiety, it appears to increase biases towards perceiving anger (away from happiness). Trait anxiety alone does not appear to be associated with facial emotion processing.

Abstract
Recent social protests and gatherings in the USA have prompted law enforcement agencies to increase their use of less lethal impact munitions (LLIMs) for crowd control. Media reports and firsthand accounts have indicated that many of the LLIMs are impacting individuals in the head and neck regions. There is very little data available on the risk of injury (ROI) from LLIM impacts to these body regions. The Facial and Ocular CountermeasUre for Safety (FOCUS) surrogate headform was used to assess the ROI (fracture) from LLIM impacts. LLIMs were fired at the FOCUS headform to determine the ROI to the frontal and maxilla bones. Sixteen different LLIMs were assessed which included 12-gauge, 37-mm, and 40-mm caliber projectiles from five manufacturers. The LLIMs included bean bag style, rubber, and foam/sponge projectiles. Each LLIM was tested multiple times to determine the average ROI. The average peak resultant frontal bone force ranged from 2.0 to 7.6 kN which represented ROIs from ~ 30% up to 95%. The average peak resultant maxilla bone force ranged from 1.0 to 4.4 kN which represented ROIs from ~ 30% up to 99%. In general, 12-gauge LLIMs had a lower ROI than the larger caliber LLIMs and the rubber projectiles had a lower ROI than the bean bag style projectiles. Due to the relative thickness, the maxilla has a much lower fracture force than the frontal bone, and this was borne out in the ROIs from the maxilla impacts. Impacts to both bones showed a positive correlation between normalized energy and resultant force (p < 0.01). The slope of the plotted resultant force against the normalized energy for the 12-gauge munitions was significantly smaller compared to larger calibers for both impact sites, frontal (p = 0.031), and maxilla (p < 0.001).

Abstract
Regions sensitive to specific object categories as well as organized spatial patterns sensitive to different features have been found across the whole ventral temporal cortex (VTC). However, it is unclear that within each object category region, how specific feature representations are organized to support object identification. Would object features, such as object parts, be represented in fine-scale spatial tuning within object category-specific regions? Here, we used high-field 7T fMRI to examine the spatial tuning to different face parts within each face-selective region. Our results show consistent spatial tuning of face parts across individuals that within right posterior fusiform face area (pFFA) and right occipital face area (OFA), the posterior portion of each region was biased to eyes, while the anterior portion was biased to mouth and chin stimuli. Our results demonstrate that within the occipital and fusiform face processing regions, there exist systematic spatial tuning to different face parts that support further computation combining them.

Abstract
A human face contains a wealth of information about an individual, with which an observer can instinctively make a judgment on the attractiveness of the face. However, despite the profuse literature on facial and smile attractiveness, their origins, determinants, and perceptions remain controversial. The axiom in face processing research is that a face is perceived as an amalgamation of its features, and is referred to as "whole" or "holistic" perception. It is pertinent to the clinician involved in the provision of esthetic restorations to understand this holistic process of face recognition and perception of smile attractiveness. This review paper addresses face recognition and perception of attractiveness by reviewing the holistic perception of faces, including the multidimensional face-space model, and also reviews the smile and facial attractiveness according to the average, multiple motive, and secondary sex characteristics theories.

Abstract
Face masks impact social interactions because emotion recognition is difficult due to face occlusion. However, is this enough to conclude that face masks negatively impact social interactions? We investigated the impact of face masks on invariant characteristics (sex, age), trait-like characteristics (trustworthiness, attractiveness, and approachability), and emotional expressions (happiness and excitability). Participants completed an online survey and rated masked and no-masked faces. The same face remained masked or no-masked throughout the survey. Results revealed that, when compared to no-masked faces, masked happy faces appeared less happy. Face masks did not negatively impact the ratings of other characteristics. Participants were better at judging the sex of masked faces. Masked faces also appeared younger, more trustworthy, more attractive, and more approachable. Therefore, face masks did not always result in unfavorable ratings. An additional post hoc modeling revealed that trustworthiness and attractiveness ratings for masked faces predicted the same trait ratings for no-masked faces. However, approachability ratings for no-masked faces predicted the same trait ratings for masked faces. This hinted that information from masked/no-masked faces, such as from the eye and eye region, could aid in the understanding of others during social interaction. Future directions were proposed to expand the research.

Abstract
This study was conducted to achieve an understanding of the potential applications of Kinesio Taping® (KT) in the craniomaxillofacial region. A comprehensive search of pertinent literature was performed through PubMed, Medline, Google Scholar, ProQuest, and ScienceDirect. The focused question that was addressed was, "What are the potential applications of KT in the craniomaxillofacial region?". The preliminary search identified 52 studies. Once duplicates were removed, the remaining 43 titles/abstracts were screened, where 9 studies were excluded and the remaining 34 were assessed. Three additional studies were obtained through reference review of the retrieved articles. KT is being used for the management of various conditions, including temporomandibular joint disorders, side effects associated with maxillofacial surgeries, various neurological conditions, etc. KT has not been proven as a reliable independent treatment option; however, it is considered to be useful as a complementary option to improve treatment outcomes for various conditions.

Abstract
Aim: This study explores interoceptive attentiveness (IA) influence on autonomic reactivity related to pain and self-regulation during situations evoking physiological mirroring for pain.Methods: 20 participants observed face/hand, painful/non-painful stimuli in an individual versus social condition while the autonomic response was measured [Electrodermal activity, Pulse Volume Amplitude (PVA), and Heart Rate (HR)] was measured. The sample was divided into experimental (EXP) subjects, required to focus on their interoceptive correlates while observing the stimuli, and the control (CNT) group. HR inter-beat interval (IBI), and HR Variability (HRV) were calculated.Results: Results showed high accuracy to painful and non-painful stimuli recognition. Regarding autonomic indices, higher PVA values were detected for hand painful versus non-painful stimuli, whereas for the EXP group a significant activation of IBI was found for face painful vs non-painful stimuli.Conclusion: In the context of observation of pain in others, PVA and IBI could be respectively markers of mirroring mechanisms and autonomic self-regulation mediated by IA.

Abstract
The facial artery (FA) is the main artery supplying the anterior face, making this artery a very important structure to consider while performing plastic and reconstructive procedures. The literature shows discrepancies in anatomical classifications and the frequency of occurrence of individual variations. Therefore, the goal of this meta-analysis is to provide surgeons with helpful knowledge about the variety of the termination of FA. Articles with data about the termination of the FA were found in major online medical databases such as PubMed, Scopus, Embase, Web Of Science, and Cochrane Library. A total of 1346 articles were initially evaluated by two independent reviewers. Out of those, 24 articles matched the required criteria, and were used in this meta-analysis. A total of 2119 studied FAs were included in this study. The FA termination patterns were divided into five previously classified types. The data show that the FA terminates most frequently as the lateral nasal or angular artery with the prevalence for this group being 69.81% (95% confidence interval [CI]: 59.83%-78.94%). Authors believe that this is the most accurate and up to date study regarding termination patterns and the prevalence of the FA. The results of this meta-analysis could provide a helpful tool for surgeons preforming plastic and cosmetic procedures, especially when injecting dermal fillers or choosing and preforming facial flaps. Detailed anatomical knowledge about the FA may prevent potential surgical complications.

Abstract
While some people enjoy looking at their faces in the mirror, others experience emotional distress. Despite these individual differences concerning self-viewing in the mirror, systematic investigations on this topic have not been conducted so far. The present eye-tracking study examined whether personality traits (self-esteem, narcissism propensity, self-disgust) are associated with gaze behavior (gaze duration, fixation count) during free mirror viewing of one's face. Sixty-eight adults (mean age = 23.5 years; 39 females, 29 males) viewed their faces in the mirror and watched a video of an unknown person matched for gender and age (control condition) for 90 s each. The computed regression analysis showed that higher self-esteem was associated with a shorter gaze duration for both self-face and other-face. This effect may reflect a less critical evaluation of the faces.

Effects of Emotional Expressiveness of a Female Digital Human on Loneliness, Stress, Perceived Support, and Closeness Across Genders: Randomized Controlled Trial. J Med Internet Res 2021; 23:e30624.

Abstract
Background Loneliness is a growing public health problem that has been exacerbated in vulnerable groups during the COVID-19 pandemic. Social support interventions have been shown to reduce loneliness, including when delivered through technology. Digital humans are a new type of computer agent that show promise as supportive peers in health care. For digital humans to be effective and engaging support persons, it is important that they develop closeness with people. Closeness can be increased by emotional expressiveness, particularly in female relationships. However, it is unknown whether emotional expressiveness improves relationships with digital humans and affects physiological responses. Objective The aim of this study is to investigate whether emotional expression by a digital human can affect psychological and physiological outcomes and whether the effects are moderated by the user’s gender. Methods A community sample of 198 adults (101 women, 95 men, and 2 gender-diverse individuals) was block-randomized by gender to complete a 15-minute self-disclosure conversation with a female digital human in 1 of 6 conditions. In these conditions, the digital human varied in modality richness and emotional expression on the face and in the voice (emotional, neutral, or no face; emotional or neutral voice). Perceived loneliness, closeness, social support, caring perceptions, and stress were measured after each interaction. Heart rate, skin temperature, and electrodermal activity were assessed during each interaction. 3-way factorial analyses of variance with post hoc tests were conducted. Results Emotional expression in the voice was associated with greater perceptions of caring and physiological arousal during the interaction, and unexpectedly, with lower feelings of support. User gender moderated the effect of emotional expressiveness on several outcomes. For women, an emotional voice was associated with increased closeness, social support, and caring perceptions, whereas for men, a neutral voice increased these outcomes. For women, interacting with a neutral face was associated with lower loneliness and subjective stress compared with no face. Interacting with no face (ie, a voice-only black screen) resulted in lower loneliness and subjective stress for men, compared with a neutral or emotional face. No significant results were found for heart rate or skin temperature. However, average electrodermal activity was significantly higher for men while interacting with an emotional voice. Conclusions Emotional expressiveness in a female digital human has different effects on loneliness, social, and physiological outcomes for men and women. The results inform the design of digital human support persons and have theoretical implications. Further research is needed to evaluate how more pronounced emotional facial expressions in a digital human might affect the results.

Hill KE, Neo WS, Deming E, Hamrick LR, Kelleher BL, Foti D. Mother-infant convergence of event-related potentials elicited by face and object processing. Dev Psychobiol 2021; 63:e22211. [PMID: 34813105 DOI: 10.1002/dev.22211] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/15/2021] [Revised: 08/23/2021] [Accepted: 10/12/2021] [Indexed: 11/07/2022]
Abstract
Prior work has provided conceptual support for developmental changes in face and object processing, such that: face processing, as captured by the N290 event-related potential (ERP) component in infancy, may develop into the N170 in adulthood; and motivated attention, as captured by the negative central (Nc) in infancy, may develop into the late positive potential (LPP). The present study examined these neural correlates in 12-month-old infants and their mothers (N = 33 dyads). Dyads completed a viewing task consisting of familiar and novel face and toy stimuli while electroencephalography was recorded. Results suggest that for mothers, the N170 was larger for faces than toys, regardless of familiarity, and the LPP was largest for familiar faces. In infants, the N290 was somewhat larger for faces than toys (p < .10); the Nc did not vary by condition. Adult ERPs demonstrated fair to good reliability; reliability of infant ERPs was lower and was influenced by looking behaviors. Intergenerational associations were strongest between the LPP and Nc, particularly when electrode and time window were taken into account. Refinement of data handling and ERP scoring procedures for infant ERPs are crucial next steps for estimation of intergenerational associations and further examination of developmental changes in face and object processing.

Abstract
BACKGROUND The human face significantly affects the individuals' quality of life, attitude, and mental state. The study of anatomy would always be on the spotlight, as the beauty of the face is desired by humans worldwide. However, age, stress, and negative emotions could lead to stimulation of the corrugator supercilii and procerus muscles in the glabellar region and, subsequently, to alterations in face's characteristics, which could be associated with isolation and avoidance of engaging in social contacts. AIMS Here, we aimed to examine the degree to which treatment with botulinum toxin type A (BoNT A) can affect patients' quality of life and mental state. PATIENTS/METHODS The data collection was performed using 11 questionnaires, which were filled by 83 individuals who underwent BoNT A treatment (sex, 95% female and 5% male; mean age, 48 years). RESULTS The results showed that the treatment with BoNT A improved the patients' social and psychological behavior, and their opinion regarding their appearance. This effect developed within 1 month following completion of the treatment. Moreover, the effect was higher in patients' social behavior and was better in patients aged 40-49 years compared to those aged <40 and ≥49 years. CONCLUSIONS Thus, BoNT A treatment could be considered as an important way to improve the social behavior and socialization of individuals by raising their psychology and self-esteem.

Abstract
This study examines the influence of an indigenous concept – face on online purchases in China. Specifically, we test the mediating role of materialism and the moderating role of price consciousness. We conduct a survey of 315 Chinese consumers. The results demonstrate that consumers tend to make online purchases to satisfy some facets of their materialistic needs and then gain face, especially for those highly conscious of price. The current research can help both scholars and practitioners better understand Chinese consumers and their decision-making processes. Implications, limitations, and directions for future research are also provided.

Abstract
Hidradenitis suppurativa is a chronic, debilitating inflammatory skin disease. Case reports of individuals with hidradenitis suppurativa presenting exclusively on the face, as well as reports of individuals with HIV and hidradenitis suppurativa, are rare. Here, we present the case of an HIV-positive man who presented with hidradenitis suppurativa localized only on his face. We also review facial hidradenitis suppurativa and hidradenitis suppurativa in HIV patients.
