Shrunken heads are a mummification phenomenon unique to South America. Ceremonial tsantsa are ritually reduced heads from enemy victims of the Shuar, Achuar, Awajún (Aguaruna), Wampís (Huambisa), and Candoshi-Shapra cultures. Commercial shrunken heads are comparatively modern and fraudulently produced for the curio-market, often using stolen bodies from hospital mortuaries and graves. To achieve shrinkage and desiccation, heads undergo skinning, simmering (in water) and drying. Considering the intensive treatments applied, this research aims to identify how the facial structure can alter and impact identification using post-mortem depiction...

BACKGROUND: Reconstruction of nasal tip defects presents a significant challenge for plastic surgeons. The form, function, and aesthetic appeal of all nasal subunits must be addressed. The expanded paramedian forehead flap is a good choice for nasal reconstruction, providing similar texture, structure, and skin color, and high reliability. This article discusses the authors' modification of the expanded paramedian forehead flap in reconstructing defects on or around the nasal tip. METHODS: Twenty-two patients with nasal defects located on or around the nasal tip were treated in our institution...

PURPOSE: To determine if frontalis muscle contraction can be induced by manipulating visual and eyelid proprioceptive inputs through simulating visual deprivation and ptosis. METHODS: Volunteers without prior eyelid or forehead pathologic study were recruited for this nonrandomized, prospective study. Baseline and study phase brow positions were documented. The first phase was to simulate visual deprivation and the second to simulate ptosis. The dominant eye was used for each phase...

The multimillion-euro fertility industry increasingly tailors its treatments to infertile people who are willing to travel across national borders for treatments inaccessible at home, especially reproductive tissue donor treatments. Finland is the Nordic destination for access to donor eggs, particularly for Swedes and Norwegians hoping for a donor match that will achieve a child of phenotypically plausible biological descent. Finns are seen as Nordic kin, and the inheritability of "Nordicness" is reinforced at clinics...

The aim of this study was to analyze eyebrow shapes in portraits of Chinese empresses of Ming and Qing dynasties.The frontal portraits of 20 Ming empresses and 24 of Qing in which the eye and eyebrows were identifiable were measured and analyzed. The arch shape did not differ significantly (P > 0.05) between Ming and Qing. The head-up type (66.6%) was significantly more common (P < 0.001), than tail-up (13.6%), horizontal (13.6%), and arched (6.8%). The brow arches of Ming and Qing empresses were classified as 5 arch types: L (Lamas), A (Anastasia), H (Hwang), M (Empress Ma), and D (Empress Du)...

A new Isospora (Apicomplexa:Eimeriidae) species is described from a silvereye (Zosterops lateralis) in Western Australia. Sporulated oocysts of this species are spherical, 24.2 (23.1-25.2) × 23.3 (22.8-23.9) μm, with a shape index (length/width) of 1.02, and with a smooth bi-layered oocyst wall, 1.2 μm thick (outer layer 0.9 μm, inner 0.3 μm). A polar granule is present, but the oocyst residuum and a micropyle are absent. The ovoid-shaped sporocysts are 16.1 (15.7-17.3) × 10.5 (15.7-17.3) μm and have a shape index of 1...

Visual landmarks are important navigational aids to many animals, and when more than one is available their juxtaposition can convey valuable new information to a navigator about progress toward a goal, depending on the landmarks' comparative distinctiveness. We investigated the effect of presenting rock ant colonies (Temnothorax albipennis) with identical horizontal landmarks either side of their route, versus one horizontal landmark paired with a sloping landmark, as they navigated to a new nest site. Our findings suggest that ants can obtain more navigational information from a combination of dissimilar landmarks: the average tortuosity of the route taken between old and new nests was significantly lower when a horizontal landmark was paired with a monotonically downward sloping landmark (the paths were more direct)...

OBJECT: Cost-utility analysis, a special case of cost-effectiveness analysis, estimates the ratio between the cost of an intervention to the benefit it produces in number of quality-adjusted life years. Cervical deformity correction has not been evaluated in terms of cost-utility and in the context of value-based health care. Our objective, therefore, was to determine the cost-utility ratio of cervical deformity correction. METHODS: Retrospective review of a prospective, multicenter cervical deformity database...

Background: Upper eyelid dermatochalasis often triggers frontalis hyperactivity in an effort to elevate the upper lids away from the visual axis. Similarly, prior neuromodulator treatment of the brow depressors may cause false elevation of the brows, diminishing the extent of preoperative brow ptosis or dermatochalasis. Studies have quantified postoperative brow ptosis and recurrent dermatochalasis following upper blepharoplasty, but a methodology to predict the postoperative brow position remains to be elucidated...

PURPOSE: Ankylosing spondylitis (AS) can result in severe cervico-thoracic kyphotic deformity (CTKD). Few studies have addressed the relationship between cervico-thoracic osteotomies in AS and health-related quality of life scores. The aim of this study is to evaluate the impact of cervico-thoracic osteotomy (CTO) on improving quality of life for patients with fixed CTKD. METHODS: A database of all patients who underwent a CTO for CTKD in patients with AS was created...

Facing a remarkably changing world, researchers have gradually shifted emphasis from successful experiences to failures. In the current study, we build a model to explore the relationship between project commitment and learning from failure, and test how emotion (i.e., perceived shame after failure) and cognition (i.e., attribution for failure) affect this process. After randomly selecting 400 firms from the list of high-tech firms reported by the Beijing Municipal Science and Technology Commission, we use a two-wave investigation of the employees, and the final sample consists of 140 teams from 58 companies in the technology industry in mainland China...

PURPOSE/OBJECTIVES: Overall non-melanoma head and neck skin cancer has a good prognosis; however, rarely patients have an aggressive variant which results in orbital invasion via perineural spread or direct extension. Despite these consequences, there are limited published studies defining this clinical entity. The main objectives of the current study are to describe orbital invasion patterns of non-melanoma head and neck skin cancers and their impact on survival. METHODS: Retrospective case series from a tertiary-care, academic institution performed between 2004 and 2014...

PURPOSE: Benign masses of the eyebrow and forehead are common in pediatric patients and can result in facial asymmetry, discomfort, or super-infection. Excision is classically conducted via an incision directly over the mass, which can produce sub-optimal cosmesis. Recently, an endoscopic approach using pediatric brow-lift equipment has been adopted. We reviewed our center's experience with endoscopic removal of benign facial lesions and compared these cases with an equivalent series of open cases...

While many of the basic tenants of upper lid blepharoplasty remain constant regardless of skin type, the thick-skinned eyelid patient requires special consideration. The brow may be naturally lower in the thick-skinned patient. These patients are more prone to having the brow pulled downward while attempting to remove redundant skin. There may also be more fat in the medial and central compartments. There may be fat in a lateral compartment overlying the lacrimal gland. Patient's expectations for a deep lid sulcus and complete excision of redundant skin may not be possible...

One of the first signs of aging belongs to the upper third of the face. With the aging process, mestizo facial features become more prominent. The thicker skin-soft tissue envelope (S-STE) has a tendency to sag more, hooding of the eyelids tends to be more pronounced, and there is a tendency for eyebrows to droop, specifically the tail of the brows, because of the loss of support. A "tired" or "sad" look implies that the complex eyebrow-upper eyelid is showing one or more of these signs...

This work describes a new strategy for fabricating mixed matrix composites containing layered metal-organic framework (MOF)/polymer films as new functional barriers for chemical warfare agent protection. Through the use of mechanically robust polymers as the top and bottom encasing layers, a high MOF loading, high performance core layer can be sandwiched within. We term this multifunctional composite "MOFwich". We found that the use of elastomeric encasing layers enabled core layer reformation after breakage, an important implication for composites and membranes alike...

PURPOSE: The shape and position of the eyebrows are among the most important facial features from an esthetic point of view. However, significant cultural differences exist with respect to the eyebrow shape and position that are considered ideal. The purpose of this study was to identify the position and shape of eyebrows preferred by Korean women and to apply these, including forehead lifts, to the clinics. METHODS: The authors took full facial photographs in the Frankfort plane of Korean women aging from young childhood to their 50s...
