OBJECTIVE: The purposes of this study were to determine the intra-rater test-retest reliability of a smart phone-based measurement tool (SBMT) and a three-dimensional (3D) motion analysis system for measuring the transverse rotation angle of the pelvis during single-leg lifting (SLL) and the criterion validity of the transverse rotation angle of the pelvis measurement using SBMT compared with a 3D motion analysis system (3DMAS). METHOD: Seventeen healthy volunteers performed SLL with their dominant leg without bending the knee until they reached a target placed 20 cm above the table...

OBJECTIVES: To determine a paradigm for evaluating and managing maxillary sinus conditions before dental implantation via preoperative sinonasal assessment. STUDY DESIGN: Prospective cohort study. METHODS: Eighty-four patients who underwent dental implantation with or without sinus augmentation were included. Maxillary sinus conditions were classified into groups 1 to 6 according to cone-beam computed tomography (CT) findings: 1) nonspecific findings, 2) solitary polyp or cyst, 3) mucosal thickening, 4) air-fluid level or fluid accumulation, 5) near-total opacification of the maxillary or other paranasal sinus, and 6) calcification spots in the maxillary sinus...

Classification measures play essential roles in the assessment and construction of classifiers. Hence, determining how to prevent these measures from being affected by individual observations has become an important problem. In this paper, we propose several indexes based on the influence function and the concept of local influence to identify influential observations that affect the estimate of the area under the receiver operating characteristic curve (AUC), an important and commonly used measure. Cumulative lift charts are also used to equipoise the disagreements among the proposed indexes...

The eyelid-cheek junction is a key area which generates many comments: from looking tired to looking good or rested, without forgetting charm, beauty, and a youthful appearance. In spite of many interesting medical and surgical procedures, treating this area is sometimes difficult and results are not always up to our expectations. Standardized blepharoplasty, which has often been improperly used, has shown its limits. Since the latest refinements, lipostructure has revolutionised blepharoplasty and serving as a reference, it has become an established technique...

In industrial societies, work-related musculoskeletal disorders are common among workers, frequently resulting in recurrent injuries, work disability, and multiple compensation claims. The risk of idiopathic musculoskeletal injuries is thought to be more than twice the risk of any other health problem among workers in the health care sector. This risk is highly prevalent particularly among workers whose job involves frequent physical tasks, such as patient lifting and transfer. Workers with recurrent occupational injuries are likely to submit multiple work disability claims and progress to long-term disability...

The neck is an aesthetic unit for which a rejuvenation request is sometimes very targeted or ore often encompassed in a global surgical project of face-lift. To obtain a long lasting outcome, the plastic surgeon has to make a full, detailed, and exhaustive analysis of the neck in order to choose the best indication within the multiple surgical tools. A full clinical examination is the key point, every aspects are outlined. The numerous surgical choices are described, illustrated, and sometimes revisited in the light of targeted anatomical studies...

Many scorpion accidents occur in the Brazilian Amazonian region and are frequently caused by Tityus obscurus. Approximately 5% of the crude venom of this species is composed of short linear, non-disulfide-bridged peptides, which have not been intensively investigated. As a consequence, only a few of these peptides have been structurally and functionally characterized to date. In the present paper, the peptide fraction of the venom was subjected to peptide profiling using an LCMS-IT-TOF/MS and MS(n) system. The analysis detected 320 non-disulfide bond-containing peptides (NDBPs), of which twenty-seven had their sequences assigned; among them, thirteen peptides were characterized, constituting novel toxins in T...

To examine the potential of chitosan-based agents for submucosal injection in endoscopic techniques, a chitosan derivative was prepared with lactose moieties linked to the amino groups of its glucosamine units (CH-LA). After dissolving CH-LA in neutral pH solutions, including physiological saline (CH-LA-S), its response to different concentrations of anionic glycosaminoglycans and proteins in the surrounding environment was examined. The CH-LA-S form changed in the presence of sulfated glycosaminoglycans (heparin, chondroitin sulfate, and mucin) and protein (fibrinogen)...

Kian Karimi, Alexandra Reivitis
Traditional rejuvenation techniques include chemical peels, rhytidectomy of the skin, laser resurfacing, injection of dermal fillers and neurotoxins, and invasive surgical procedures. Patients with brow ptosis, jowl formation, and deepening nasolabial folds currently seek antiaging procedures with no incisions and minimal downtime such as thread-lifting with barbed sutures. The present report describes a case in which polydioxanone threads were used to lift the lower third of a patient's face. Fillers were used to supplement the results achieved by the thread lift because often, when tissue has been lifted, volume deficits are revealed, which can be corrected with dermal fillers...

Seth Peterson, Thomas Denninger
BACKGROUND AND PURPOSE: Hip abductor dysfunction is common in individuals with chronic low back pain (CLBP). Previous research investigating abductor strengthening in the heterogeneous CLBP population is sparse and has failed to target those patients most likely to benefit. The aim of the current case series was to describe the physical therapy management and outcomes of 3 patients with CLBP matching a previously identified subgroup characterized by substantial hip abductor weakness. CASE DESCRIPTION: Three nonconsecutive patients with CLBP-a 77-year-old man, a 78-year-old woman, and an 85-year-old woman-were treated in an outpatient physical therapy clinic...

PURPOSE: Since different subspecialties are currently performing a variety of upper facial rejuvenation procedures, and the level of knowledge on the ocular and periocular anatomy and physiology is different, this review aims to highlight the most important preoperative examinations and tests with special attention to the eye and periocular adnexal structures for general ophthalmologist and specialties other than oculo-facial surgeons in order to inform them about the fine and important points that should be considered before surgery to have both cosmetic and functional improvement...

Alan Moy
The National Institutes of Health (NIH) announced its plans to lift its moratorium on funding research that involves injecting human embryonic stem cells into animal embryos, which would allow for the creation of part-human and part-animal organisms known as chimeras. The NIH allowed only one month to receive public comments in the midst of a presidential election campaign. Lifting the moratorium means that, for the first time, the federal government will begin spending taxpayer dollars on the creation and manipulation of new organisms that would blur the line between humans and animals...

Daniel R Kattnig, P J Hore
Birds have a remarkable ability to obtain navigational information from the Earth's magnetic field. The primary detection mechanism of this compass sense is uncertain but appears to involve the quantum spin dynamics of radical pairs formed transiently in cryptochrome proteins. We propose here a new version of the current model in which spin-selective recombination of the radical pair is not essential. One of the two radicals is imagined to react with a paramagnetic scavenger via spin-selective electron transfer...

Injectable substances known as fillers are used to palliate age-related atrophy and ptosis, and for their so-called "pseudo-lifting" action. They do not replace face and neck lift, but allow it to be postponed or, when injected after surgical lifting, make the result durable. Hyaluronic acid has a predominant and unchallenged place among fillers, well ahead of poly-L-lactic acid or calcium hydroxyapatite. Approaches and injection methods are the same for all fillers, corresponding to those for autologous fat injection, the reference substance, with a few particularities...

Working sheepdog trials test the attributes of dogs as well as the dogmanship and stockmanship skills of handlers. They generally include standard elements such as outrun, lift, fetch, drive, shed, pen and single to test all facets of the work that dogs perform on a farm. While both male and female handlers participate, these trials are traditionally dominated by male handlers. Both male and female dogs compete on equal terms within the same events. Drawing data from files (n = 60) downloaded from YouTube, the current study explores whether behaviours of dogs and their handlers during sheepdog trials differ between handler gender and dog sex at different levels of competition...

Surface damage on honeycomb aircraft panels is often measured manually, and is therefore subject to variation based on inspection personnel. Eddy current testing (ECT) is sensitive to variations in probe-to-specimen spacing, or lift-off, and is thus promising for high-resolution profiling of surface damage on aluminum panels. Lower frequency testing also allows inspection through the face sheet, an advantage over optical 3D scanning methods. This paper presents results from the ECT inspection of surface damage on an approximately flat aluminum honeycomb aircraft panel, and compares the measurements to those taken using optical 3D scanning technology...

Sasha Reschechtko, Mark L Latash
We combined the theory of neural control of movement with referent coordinates and the uncontrolled manifold hypothesis to explore synergies stabilizing the hand action in accurate four-finger pressing tasks. In particular, we tested a hypothesis on two classes of synergies - those among the four fingers and those within a pair of control variables - stabilizing hand action under visual feedback and disappearing without visual feedback. Subjects performed four-finger total force and moment production tasks under visual feedback; the feedback was later partially or completely removed...

The human ether-à-go-go channel (hEag1 or KV10.1) is a cancer-relevant voltage-gated potassium channel that is overexpressed in a majority of human tumors. Peptides that are able to selectively inhibit this channel can be lead compounds in the search for new anticancer drugs. Here, we report the activity-guided purification and electrophysiological characterization of a novel KV10.1 inhibitor from the sea anemone Anthopleura elegantissima. Purified sea anemone fractions were screened for inhibitory activity on KV10...
