Wen Xu, Patrick A Gerety, Jing Li, Scott P Bartlett, Jesse A Taylor
BACKGROUND: Frontal sinus pneumatization plays an important role in brow protrusion, and absence of frontal sinus development may be associated with brow retrusion. Using unicoronal craniosynostosis as a model, the authors studied the relationship among frontal sinus volume, supraorbital retrusion, and brow position. METHODS: The authors conducted a retrospective review of unicoronal craniosynostosis patients with head computed tomographic scans and photographs taken from ages 5 to 18 years...

Mario Pelle-Ceravolo, Matteo Angelini
Background: The height of the eyebrow is less crucial aesthetically than is the relationship between the lateral and medial portions of the brow. Although various surgical procedures are effective in raising the brow, the authors maintain that transcutaneous brow shaping (TBS) is the only technique that enables precise shaping of the brow and correction of minor asymmetries. Objectives: The authors described their experiences with direct TBS alone or in conjunction with blepharoplasty and facelift...

PURPOSE: To determine the necessity of rehabilitative surgical procedures for no implant anophthalmic sockets, and predictive factors of corrective operations after secondary orbital implantation. MATERIAL AND METHODS: Nineteen unilateral anophthalmic patients without orbital implant were included. The distance of eyebrow, upper eyelid margin, and lower eyelid margin from the horizontal medial canthal line (BM, UM, and LM, respectively) was measured using photographs...

INTRODUCTION: Although some studies addressed the differences between subciliary and transconjunctival approaches, no previous prospective comparative study on displaced zygomaticomaxillary complex (ZMC) fracture that repaired by three-point internal fixation using also upper gingivolabial incision and upper eye lid incision. So, the effect of these incisions on the comparison was not investigated. PURPOSE: The purpose of this study was to compare transconjunctival and subciliary approaches for open reduction and internal rigid fixation (OR/IF) of ZMC fractures...

Chlorine (Cl2) and hydrogen chloride (HCl) are heavily utilized industrial chemicals that present significant respiratory health risks. The metal-organic framework UiO-66-NH2 has shown an unprecedented ability in powder form to remove chlorine gas. Here, we engineered UiO-66-NH2 into 20×40 mesh granules and evaluated their ability to remove chlorine and hydrogen chloride gas challenges. The exposed materials were characterized with nitrogen isotherms, powder X-ray diffraction, and attenuated total reflectance - Fourier transform infrared spectroscopy...

The 2015 National HIV/AIDS Strategy renewed its goal of increasing access to care for people living with HIV/AIDS (PLWHA) and called for an increased focus on linkage to care efforts. As many PLWHA face multiple barriers to care and live on the margins of society, adoption of intensive outreach activities is necessary to engage the most disenfranchised PLWHA into care and to ultimately end the HIV epidemic. The Bay Area Network for Positive Health (BANPH), comprising 12+ agencies, established a network outreach model for our linkage-to-care project to engage the hardest-to-reach populations in the San Francisco Bay Area...

Avian metabolic responses demonstrate considerable diversity under fluctuating environmental conditions, a well-studied example being the seasonal upregulation of basal metabolic rate (BMR) and summit metabolism (Msum) in temperate species experiencing harsh winters. Fewer studies have examined seasonal metabolic acclimatization in subtropical or tropical species. We investigated seasonal metabolic variation in an Afrotropical ploceid passerine, the white-browed sparrow-weaver (Plocepasser mahali; ∼47 g), at three sites along a climatic gradient of approximately 7°C in winter minimum air temperature (Ta)...

Dómhnall J Jennings, Martin P Gammell
Individuals often display a preference for one side of their body during aggressive encounters. This may be a lateralized preference for using one structure of a bilateral trait during display or physical attack, or for keeping the opponent in one visual field. Alternatively, it may be the case that behavioural lateralization and the degree of symmetry expressed by bilateral structures are correlated forms of developmental instability. We examined whether there was an association between lateralization during a lateral display and different measurements of antler size and symmetry (beam length, beam circumference, brow tine length and coronet circumference)...

Browpexy surgery is a minimally invasive surgical adjunct to upper blepharoplasty. The traditional internal (IB) approach is well documented, while the newer external (EB) variant has only recently been described. To date, there is little quantitative data to evaluate the efficacy of either procedure, and no data to compare results between the two. We determine the efficacy of, and compare surgical results between, internal and external browpexy surgery in lifting the central and lateral brow. A 3.5-year retrospective review of patients undergoing internal and external browpexy surgery to assess the amount of central and lateral lift to the brow was performed...

Knowledge of variable anatomy is key for excellent outcomes from the administration of botulinum toxin for aesthetic purposes. One must understand the location and function of each facial muscle to predict the patient's desired outcome. One concept often overlooked by injectors is the understanding of the target muscle's depth. In addition, a firm understanding of where each facial muscle originates and attaches can be essential to correctly identifying and injecting the correct muscle with botulinum toxin...

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)...
