Arm contour improvement is a desired goal of the massive weight loss and the aging population who want to maintain the arm aesthetics. Brachioplasty is a growing and safe procedure to improve the arm contour and different approaches and innovative treatment options have been described since the 1930s. This paper reviews the relevant literature in arm contouring including surgical and nonsurgical procedures used to aesthetically improve the arm. A comprehensive literature review was performed using the words "brachioplasty," "arm lift," "arm contouring," "arm liposuction," "noninvasive arm lift," "minimally invasive arm lift...

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)...

The underrepresentation of women in technical and STEM fields is a well-known problem, and stereotype threatening situations have been linked to the inability to recruit and retain women into these fields. Virtual reality enables the unique ability to perform body-swap illusions, and research has shown that these illusions can change participant behavior. Characteristically people take on the traits of the avatar they are embodying. We hypothesized that female participants embodying male avatars when a stereotype threat was made salient would demonstrate stereotype lift...

In 2011, load limits for manual lifting were adopted in Iran to protect workers from low back injury without prior testing of accuracy with Iranian workers. This investigation examined how accurate the adopted ACGIH TLVs at the allowable limits predict risk for LBP disorders for a group of Iranian workers using biomechanical criteria. Testing took place in the laboratory with participants completing a series of 2-handed lifting tasks as defined in the Iranian Guideline for Manual Lifting. To test accuracy, both compression and shear forces were estimated for fifteen male Iranian workers who completed 25 lift combinations that varied in height and reach with the maximal allowable load...

The Sauvé-Kapandji procedure is a reliable option for patients with various disorders of the distal radioulnar joint (DRUJ). However, postoperative pain over the proximal ulnar stump frequently develops during forearm rotation or when lifting heavy objects, although many clinically satisfactory results have been reported. This stump pain has been suggested to result from dynamic instability of the proximal ulnar stump. Several types of tenodesis have recently been performed simultaneously with the Sauvé-Kapandji procedure to stabilize the proximal ulnar stump and thus relieve the associated pain...

Circulating tumor cells (CTCs) are rare cells that detach from primary or metastasis tumor and flow into the blood stream. Intact and viable tumor cells are needed for genetic characterization of CTCs, new drug development, and other research. Although separation of CTCs using spiral channel with two outlets has been reported, few literatures demonstrated simultaneous isolation of different types of CTCs from human blood using cascaded inertial focusing microfluidic channel. Herein, we introduce a cascaded microfluidic device consisting of two spiral channels and one zigzag channel designed with different fluid fields, including lift force, Dean drag force, and centrifugal force...

The purpose of this study was to investigate the effects of using an internal versus external focus of attention during resistance training on muscular adaptations. Thirty untrained college-aged men were randomly assigned to an internal focus group (INTERNAL) that focused on contracting the target muscle during training (n = 15) or an external focus group (EXTERNAL) that focused on the outcome of the lift (n = 15). Training for both routines consisted of 3 weekly sessions performed on non-consecutive days for 8 weeks...

The video-assisted subcutaneous destruction of the sinus tract (VADST) is a novel, minimally-invasive technique for the treatment of pilonidal sinus disease (PSD). This is an advancement of the previously described subcutaneous destruction of the sinus tract and the removal of hairs as well as the long-term vessel-loop drainage of the wound channel (DST). Although the first results of this operation seemed to be promising, some of my colleagues felt that the blind approach to this procedure could be its potential "weak point"...

The solar to electric power conversion efficiency (PCE) of perovskite solar cells (PSCs) has recently reached 22.7 % exceeding that of competing thin film photovoltaics and the market leader polycrystalline silicon. Further augmentation of the PCE towards the Shockley-Queisser limit of 33.5 % warrants suppression of radiationless carrier recombination by judicious engineering of the interface between the light harvesting perovskite and the charge carrier extraction layers. Here, we introduce a mesoscopic oxide double layer as electron selective contact consisting of a scaffold of TiO2 nanoparticles covered by a thin film of SnO2, either in amorphous (a-SnO2), crystalline (c-SnO2) or nanocrystalline (quantum dot) form (SnO2-NC)...

Humans have a remarkable ability to adjust the way they manipulate tools through a genuine regulation of grip force according to the task. However, rapid changes in the dynamical context may challenge this skill, as shown in many experimental approaches. Most experiments adopt perturbation paradigms that affect only one sensory modality. We hypothesize that very fast adaptation can occur if coherent information from multiple sensory modalities is provided to the central nervous system. Here, we test whether participants can switch between different and never experienced dynamical environments induced by centrifugation of the body...

The reference joint position of upper-limb exoskeletons is typically obtained by means of Cartesian motion planners and inverse kinematics algorithms with the inverse Jacobian; this approach allows exploiting the available Degrees of Freedom (i.e. DoFs) of the robot kinematic chain to achieve the desired end-effector pose; however, if used to operate non-redundant exoskeletons, it does not ensure that anthropomorphic criteria are satisfied in the whole human-robot workspace. This paper proposes a motion planning system, based on Learning by Demonstration, for upper-limb exoskeletons that allow successfully assisting patients during Activities of Daily Living (ADLs) in unstructured environment, while ensuring that anthropomorphic criteria are satisfied in the whole human-robot workspace...

BACKGROUND: Venous thromboembolism can be a significant cause of morbidity in the trauma population. Medical and surgical specialties have been pushing the indication for prophylactic filter placement. CASE DESCRIPTION: A 36-year-old man presented with axial lower back pain with a radicular right L2 component after lifting a heavy object. He had a history of penetrating brain trauma 3 years prior, with placement of a prophylactic inferior vena cava filter. His x-ray, computed tomography, and magnetic resonance imaging of the lumbar spine showed fracture of his filter, with migration of the fractured fragment through the inferior vena cava and into the L2-L3 disc space, and surrounding bony lysis and severe osteodiscitis...

The purpose of this report is to describe the case and management of an unexplained vitreous haemorrhage that occurred after repeated roller-coaster riding. The authors inadvertently demonstrate the value of observation over immediate surgery in certain situations and review the literature on vitreoretinal and other ocular complications after roller-coaster riding. A 26-year-old male presented 12 h after riding high-velocity roller-coasters with a left vitreous haemorrhage. A hazy view of the retina and B-scan revealed a bullous area of superior-temporal retinal lifting...

BACKGROUND: Physical inactivity is an important cause of noncommunicable diseases. Interventions can increase short-term physical activity (PA), but health benefits require maintenance. Few interventions have evaluated PA objectively beyond 12 months. We followed up two pedometer interventions with positive 12-month effects to examine objective PA levels at 3-4 years. METHODS AND FINDINGS: Long-term follow-up of two completed trials: Pedometer And Consultation Evaluation-UP (PACE-UP) 3-arm (postal, nurse support, control) at 3 years and Pedometer Accelerometer Consultation Evaluation-Lift (PACE-Lift) 2-arm (nurse support, control) at 4 years post-baseline...
