PURPOSE: To compare 3 upper eyelid retraction repair techniques and introduce novel metrics, which enhance the analysis of postoperative aesthetic outcomes. METHODS: Retrospective review with Image J 1.48 digital analysis of patients who underwent repair of thyroid-related upper eyelid retraction at the University of Iowa from 1996 to 2014 via 1 of 3 surgical techniques, septum-opening levator recession with Muellerectomy, modified septum-preserving levator recession with Muellerectomy, and modified septum-preserving full-thickness blepharotomy, was conducted...

When observing emotional expressions, similar sensorimotor states are activated in the observer, often resulting in physical mimicry. For example, when observing a smile, the zygomaticus muscles associated with smiling are activated in the observer, and when observing a frown, the corrugator brow muscles. We show that the consistency of an individual's facial emotion, whether they always frown or smile, can be encoded into memory. When the individuals are viewed at a later time expressing no emotion, muscle mimicry of the prior state can be detected, even when the emotion itself is task irrelevant...

Bioactive borate glass has been recognized to have both hard and soft tissue repair and regeneration capabilities through stimulating both osteogenesis and angiogenesis. However, the underlying biochemical and cellular mechanisms remain unclear. In this study, dynamic flow culturing modules were designed to simulate the micro-environment near the vascular depletion and hyperplasia area in wound-healing regions, thus to better investigate the mechanisms underlying the biocompatibility and functionality of borate-based glass materials...

A 54-year-old woman received multiple injections of hyaluronic acid filler to the brow region to address volume loss over a 21-month period. She then developed significant pitting edema of both upper eyelids, which persisted for 6 years. Hyaluronidase (Hyalase) was injected into the subcutaneous brows and resulted in complete resolution of the edema within 2 days. This confirms that the hyaluronic acid injected into the brows was responsible for this patient's chronic eyelid edema. This case illustrates an unusual long-term complication of periocular hyaluronic acid filler...

1.There is widespread evidence that within populations, specialists and generalists can coexist and this is particularly prevalent in marine ecosystems, where foraging specialisations are evident. 2.While individuals may limit niche overlap by consistently foraging in specific areas, site fidelity may also emerge as an artefact of habitat choice but both drivers and fitness consequences of site fidelity are poorly understood. 3.Here we examine an individual metric of site and habitat fidelity, using tracking data collected over 11 years for black-browed albatrosses (Thalassarche melanophris)...

Automatic facial action unit (AU) and expression detection from videos is a long-standing problem. The problem is challenging in part because classifiers must generalize to previously unknown subjects that differ markedly in behavior and facial morphology (e.g., heavy versus delicate brows, smooth versus deeply etched wrinkles) from those on which the classifiers are trained. While some progress has been achieved through improvements in choices of features and classifiers, the challenge occasioned by individual differences among people remains...

PURPOSE: Fentanyl is a strong µ-opioid analgesic which attenuates the stimulation of surgical invasion and tracheal intubation. However, intravenous fentanyl often induces coughing [fentanyl-induced coughing (FIC)] during induction of anesthesia. We found that the swallowing action, when requested at induction of anesthesia, attenuated FIC. In the current study, we investigated the relationship between the occurrence of FIC and the swallowing action. METHODS: The study included American Society of Anesthesiologists physical status I or II patients, aged 20-64 years, who were undergoing elective surgery...

REVIEW
Emel Başar, Ceyhun Arıcı
Botulinum neurotoxin (BoNT) is the first biological toxin used in the treatment of ophthalmic diseases and to decrease skin wrinkles as an aesthetic agent. When used appropriately, it weakens the force of muscular contraction and/or inhibits glandular secretion. The most common areas for botulinum toxin treatment are the upper face, including the glabella, forehead, brows, and lateral canthal lines, or crow's feet. By relaxing the muscles causing wrinkles, non-permanent results may be achieved with its use...

U6 small nuclear RNA (snRNA) is a key component of the active site of the spliceosome, a large ribonucleoprotein complex that catalyzes the splicing of precursor messenger RNA. Prior to its incorporation into the spliceosome, U6 is bound by the protein Prp24, which facilitates unwinding of the U6 internal stem-loop (ISL) so that it can pair with U4 snRNA. A previously reported crystal structure of the `core' of the U6 small nuclear ribonucleoprotein (snRNP) contained an ISL-stabilized A62G mutant of U6 bound to all four RNA-recognition motif (RRM) domains of Prp24 [Montemayor et al...

BACKGROUND: Optic neuropathy is a disorder characterised by dysfunction or destruction of the optic nerve tissues. Acquired causes include interruption in the blood supply, nutritional deficiency, compression by a tumour or aneurysm, trauma, and toxic types (Ambizas and Patel In US Pharm 36(4):HS2-HS6, 1). Drug-induced optic neuropathy is of the toxic type and can be defined as a clinical syndrome characterised by papillomacular bundle damage, central, or cecocentral scotoma, and reduced colour vision (Ambizas and Patel In US Pharm 36(4):HS2-HS6, 2011; Sharma and Sharma In Indian J Ophthalmol 59(2):137-141, 2)...

One of the first signs of aging belongs to the upper third of the face. At the same time, the height and shape of the eyebrows are key points of the periorbital aesthetics. A "tired" or "sad" look implies that the complex eyebrow-upper eyelid are showing one or more of these signs. Different surgical techniques as well as nonsurgical have been described to treat this area, every one of them aiming at making the patient look rested and natural. The objective of this study is to describe a technique for endoscopic browlifting, consisting of minimal incisions, a biplanar dissection, and a different fixation technique designed for helping reshape the brow...

The aim of this study was to analyze eyebrow shapes as represented in the British edition of "Vogue" over the last century (1916-2015). Photographs containing distinguishable eyebrows were selected from a book entitled "Vogue 100: A Century of Style." A total of 120 frontal pictures in which the eye and eyebrows were identifiable were included and analyzed. The relative width of the eyebrow (REW), as well as relative medial (RMH), midpupillary (RPH), and lateral (RLH) eyebrow height were measured in reference to the length of the palpebral fissure...

Human adults automatically mimic others' emotional expressions, which is believed to contribute to sharing emotions with others. Although this behaviour appears fundamental to social reciprocity, little is known about its developmental process. Therefore, we examined whether infants show automatic facial mimicry in response to others' emotional expressions. Facial electromyographic activity over the corrugator supercilii (brow) and zygomaticus major (cheek) of four- to five-month-old infants was measured while they viewed dynamic clips presenting audiovisual, visual and auditory emotions...

We investigated the relative contribution of (a) perceptual (eyes and mouth visual saliency), (b) conceptual or categorical (eye expression distinctiveness), and (c) affective (rated valence and arousal) factors, and (d) specific morphological facial features (Action Units; AUs), to the recognition of facial happiness. The face stimuli conveyed truly happy expressions with a smiling mouth and happy eyes, or blended expressions with a smile but non-happy eyes (neutral, sad, fearful, disgusted, surprised, or angry)...

BACKGROUND: The use of light level loggers (geolocators) to understand movements and distributions in terrestrial and marine vertebrates, particularly during the non-breeding period, has increased dramatically in recent years. However, inferring positions from light data is not straightforward, often relies on assumptions that are difficult to test, or includes an element of subjectivity. RESULTS: We present an intuitive framework to compute locations from twilight events collected by geolocators from different manufacturers...

Wolfgang Goymann, Ignas Safari, Christina Muck, Ingrid Schwabl
The decision to provide parental care is often associated with trade-offs, because resources allocated to parental care typically cannot be invested in self-maintenance or mating. In most animals, females provide more parental care than males, but the reason for this pattern is still debated in evolutionary ecology. To better understand sex differences in parental care and its consequences, we need to study closely related species where the sexes differ in offspring care. We investigated parental care in relation to offspring growth in two closely related coucal species that fundamentally differ in sex roles and parental care, but live in the same food-rich habitat with a benign climate and have a similar breeding phenology...
