Suleyman Nazif Orhan, Mehmet Hamit Ozyazicioglu, Abdurrahim Colak
OBJECTIVES: This study experimentally compares the efficiency of the 4 most preferred sternal closure tehniques, in 3 different deformation modes of the chest. METHODS: Polyurethane sternum models fixed by conventional wiring, steel band, ZipFix band and figure-8 wiring are tested statically under lateral distraction, longitudinal shear and torsional deformation modes. As a result, load-deformation curves are obtained. The closure efficiency of the techniques is then compared with respect to allowable load (corresponding to 2 mm displacement), rigidity, rupture load and rupture displacement...

PURPOSE: People without neurological impairments show superior motor learning when they focus on movement effects (external focus) rather than on movement execution itself (internal focus). Despite its potential for neurorehabilitation, it remains unclear to what extent external focus strategies are currently incorporated in rehabilitation post-stroke. Therefore, we observed how physical therapists use attentional focus when treating gait of rehabilitating patients with stroke. METHODS: Twenty physical therapist-patient couples from six rehabilitation centers participated...

PURPOSE: The aims of the present study were to identify information that individuals with whiplash associated disorders (WAD) need to know in the early stages of recovery and to establish whether there is a difference between what physiotherapists and whiplash-injured patients perceive as important information. METHOD: Forty-one participants were recruited (20 whiplash-injured patients, 21 physiotherapists). Participants were asked to provide five statements to one open-ended question about what they believe is the most important information individuals with WAD need to know in the early stages of recovery...

BACKGROUND: This paper examines the ability of people who are blind to construct a mental map and perform orientation tasks in real space by using Nintendo Wii technologies to explore virtual environments. The participant explores new spaces through haptic and auditory feedback triggered by pointing or walking in the virtual environments and later constructs a mental map, which can be used to navigate in real space. METHODS: The study included 10 participants who were congenitally or adventitiously blind, divided into experimental and control groups...

Nutritional effects on cancer occurrence and on treatment outcome in cancer patients may depend on food preferences and on the quantity of foods supplied. However, it has been difficult to reliably show beneficial effects of specific dietary concepts on cancer incidence. On the other hand, obesity as a result of chronic overfeeding has been linked firmly to an increased risk of a number of cancers as well as on cancer recurrence after treatment. Metabolic consequences of obesity and other components of the metabolic syndrome may be responsible for inducing and/or promoting cancer growth and should be antagonized by regular moderate physical activity in healthy subjects and in cancer survivors...

Boreal forests are an important source of timber and pulp wood, but provide also other products and services. Utilizing a simulation program and field data from a tree retention experiment in a Scots pine forest in central Sweden, we simulated the consequences during the following 100 years of various levels of retention on production of merchantable wood, dead wood input (as a proxy for biodiversity), and carbon stock changes. At the stand level, wood production decreased with increased retention levels, while dead wood input and carbon stock increased...

Hunting and sharing of meat is seen across all chimpanzee sites, with variation in prey preferences, hunting techniques, frequencies, and success rates. Here, we compared hunting and meat-eating behaviour in two adjacent chimpanzee communities (Pan troglodytes schweinfurthii) of Budongo Forest, Uganda: the Waibira and Sonso communities. We observed consistent between-group differences in prey-species preferences and in post-hunting behaviour. Sonso chimpanzees show a strong prey preference for Guereza colobus monkeys (Colobus guereza occidentalis; 74...

BACKGROUND: Better knowledge of the epidemiological characteristics of snakebites could help to take measures to improve their management. The incidence and mortality of snakebites in the Americas are most often estimated from medical and scientific literature, which generally lack precision and representativeness. METHODOLOGY/PRINCIPAL FINDINGS: Authors used the notifications of snakebites treated in health centers collected by the Ministries of Health of the American countries to estimate their incidence and mortality...

Gene silencing by heterochromatin is proposed to occur in part as a result of the ability of heterochromatin protein 1 (HP1) proteins to spread across large regions of the genome, compact the underlying chromatin and recruit diverse ligands. Here we identify a new property of the human HP1α protein: the ability to form phase-separated droplets. While unmodified HP1α is soluble, either phosphorylation of its N-terminal extension or DNA binding promotes the formation of phase-separated droplets. Phosphorylation-driven phase separation can be promoted or reversed by specific HP1α ligands...

Monica Soliman, Roger Buehler
In many decision contexts, people evaluate others based on intertemporal performance records, and commonly face a choice between two distinct profiles: performance that is consistently high versus performance that improves over time to that high level. We proposed that these two profiles could be appealing for different reasons, and thus evaluators' preferences will differ across decision contexts. In three studies, participants were presented with candidates (e.g., students, employees) displaying the two profiles, and evaluated each candidate in terms of performance, future expectations, and deservingness...

Efficient charge transport has been observed in iodide-based room-temperature ionic liquids when doped with iodine. To investigate preferred pathways for the iodide (I(-))-to-triiodide (I3(-)) exchange reaction and to clarify the origin of this high ionic conductivity, we have conducted electronic structure calculations in the crystal state of 1-butyl-3-methylimidazolium iodide ([BMIM][I]). Energy barriers for the different stages of the iodine-swapping process, including the reorientation of the I(-)···I3(-) moiety, were determined from minimum energy paths as a function of a reaction coordinate...

D Maor, C Ondhia, L L Yu, J J Chan
Lichenoid keratosis (LK), also known as benign lichenoid keratosis or lichen planus-like keratosis, is a solitary, pink to red-brown scaly plaque representing a host immunological response to a variety of precursor lesions. LK is often misdiagnosed as a dermatological malignancy owing to its clinical resemblance to basal cell carcinoma (BCC) or Bowen disease. We performed a retrospective analysis of the pathology records of a series of LK lesions with reference to the demographic features and accuracy of clinical diagnosis...

Shared airway management in patients with subglottic stenosis (SGS) is challenging for both the anaesthetist and surgeon. Various methods of airway management have been described but currently no gold standard exists. Jet ventilation has been described as the preferred technique despite a UK National Survey highlighting potential complications including pneumothorax, pneumomediastinum, surgical emphysema, hypoxia and death.
