While most models of visual word identification and reading posit that a word's visual codes are rapidly transformed onto case-invariant representations (i.e., table and TABLE would equally activate the word unit corresponding to "table"), a number of experiments have shown a lowercase advantage in various word identification and reading tasks. In the present experiment, we examined the locus of this lowercase advantage by comparing the pattern of eye movements when reading sentences in lowercase vs. uppercase...

Motivation: The simplifying assumptions that are used widely in theoretical population genetics may not always be appropriate for empirical population genetics. General computational approaches that do not require the assumptions of classical theory are therefore quite desirable. One such general approach is provided by the theory of absorbing Markov chains, which can be used to obtain exact results by directly analyzing population genetic Markov models, such as the classic bi-allelic Wright-Fisher model...

Rat models are widely used in preclinical studies investigating fracture healing. The interfragmentary movement at a fracture site is critical to the course of healing and therefore demands definition in order to aptly interpret the experimental results. Estimation of this movement requires knowledge of the fixation stiffness and loading. The characteristic loading for the rat femur has been estimated, but the stiffness of fixation used in rat studies has yet to be fully described. This study aimed to determine the 6 degree of freedom stiffness of four commonly used implants, two external fixators (RatExFix and UlmExFix), a locking plate, and a locking intramedullary nail, in all degrees of freedom and estimate the interfragmentary movement under specific physiological loads...

BACKGROUND: Little is known about extensor tendon failure following drill injury at the time of volar plate fixation. Our goals were to analyze extensor tendon injury following simulated drill penetration, and change in tendon displacement during cyclic loading following simulated drill penetration injury. METHODS: Extensor pollicis longus (EPL) and extensor carpi radialis brevis (ECRB) tendons were harvested from 9 fresh frozen cadaveric arms. Eighteen EPL and 18 ECRB samples were created from harvested tendons...

BACKGROUND: Subacute rupture of the flexor tendons secondary to distal radius fractures is well documented. Recently, accounts of flexor tendon rupture following open reduction internal fixation have been associated with volar plate fixation. However, discovery of an occult traumatic flexor tendon laceration during fixation of an acute distal radius fracture is not well described. This case indicates the importance of careful preoperative and intraoperative examination of the flexor tendons in the setting of comminuted distal radius fractures...

The Bosworth fracture is a pattern of fracture-dislocation of the ankle joint with fixed dislocation of the proximal part of the fibula behind the posterior malleolus. It is a rare injury, which requires high index of suspicion for diagnosis. Fixed dislocation of the fibula does not allow for closed reduction, so open reduction and fixation of fibula or tibia is required. We present a case report of a patient who suffered a Bosworth fracture, with associated medial malleolus fracture. She underwent surgical treatment with open reduction and internal fixation of the fibula and tibia...

In the distal radius fracture requires radiographic views that allow you to see the articular surface without interposition. The objective was to determine whether lateral radiographic projections 7 and 22° improve the analysis of this surface. METHOD: Case series study with radiographs of healthy and operated patients, in order to identify the lunate and scaphoid facets in lateral and anteroposterior projections. Qualitative analysis was made on the radiographs of the distal radius with wedges of 7 and 22° in the lateral views and 11° in the anteroposterior view...

Charcot arthropathy is defined as an articular degenerative, chronic, progressive disease that affects one or more peripheral joints, develops as a result of a failure in the normal sensory perception (pain and proprioception) in the innervation of joints located in the foot and ankle, is characterized by destructive bone lesions without the presence of infection. Neuropathy is directly associated with diabetes mellitus type 1 and 2. Surgery is indicated when there is severe involvement of soft tissue, foot joints are unstable, at the presence of chronic or recurrent ulcers or when the foot and ankle can not fit to a normal shoe, and had limitation to perform activities of daily living...

There are different opinions about the roles of local interactions and central processing capacity in visual search. This study attempts to clarify the problem using a new version of relevant set cueing. A central precue indicates two symmetrical segments (that may contain a target object) within a circular array of objects presented briefly around the fixation point. The number of objects in the relevant segments, and density of objects in the array were varied independently. Three types of search experiments were run: (a) search for a simple visual feature (color, size, and orientation); (b) conjunctions of simple features; and (c) spatial configuration of simple features (rotated Ts)...

Studies on skeletal muscle physiology face the technical challenge of appropriately processing the specimens to obtain sections with clearly visible cytoplasmic compartments. Another hurdle is the tight apposition of myofibers to the surrounding tissues. Because the process of tissue fixation and paraffin embedding leads to the shrinkage of muscle fibers, freezing is an optimal means of hardening muscle tissue for sectioning. However, a commonly encountered issue, the formation of ice crystals, occurs during the preparation of frozen sections because of the high water content of muscle...

Despite all the technological advances at the light microscopy level, electron microscopy remains the only tool in neuroscience to examine and characterize ultrastructural and morphological details of neurons, such as synaptic contacts. Good preservation of brain tissue for electron microscopy can be obtained by rigorous cryo-fixation methods, but these techniques are rather costly and limit the use of immunolabeling, which is crucial to understand the connectivity of identified neuronal systems. Freeze-substitution methods have been developed to allow the combination of cryo-fixation with immunolabeling...

Live-cell imaging is used to simultaneously capture time-lapse images of angiotensin type 1a receptors (AT1aR) and intracellular compartments in transfected human embryonic kidney-293 (HEK) cells following stimulation with angiotensin II (Ang II). HEK cells are transiently transfected with plasmid DNA containing AT1aR tagged with enhanced green fluorescent protein (EGFP). Lysosomes are identified with a red fluorescent dye. Live-cell images are captured on a laser scanning confocal microscope after Ang II stimulation and analyzed by software in three dimensions (3D, voxels) over time...

The current study addresses a discrepancy in the psycholinguistic literature about the chronology of information processing during the visual recognition of morphologically complex words. Form-then-meaning accounts of complex word recognition claim that morphemes are processed as units of form prior to any influence of their meanings, whereas form-and-meaning models posit that recognition of complex word forms involves the simultaneous access of morphological and semantic information. The study reported here addresses this theoretical discrepancy by applying a nonparametric distributional technique of survival analysis (Reingold & Sheridan, 2014) to 2 behavioral measures of complex word processing...

Lesser toe deformities are one of the most common conditions encountered by podiatric surgeons. When conservative treatments fail surgical correction is indicated. Many surgical options have been described to address the complex nature of these deformities but no perfect solution has been reported to date. However, with the continued advancement of internal fixation technology, interphalangeal joint (IPJ) arthrodesis with an intramedullary implant may be a good option. This retrospective study presents patient reported outcomes and complications at 6 months and 3 years following lesser toe proximal interphalangeal joint (PIPJ) arthrodesis with a polyketone intrameduallary implant (Toe Grip, Orthosolutions, UK)...

Rhizobium leguminosarum has two high-affinity Mn(2+) transport systems encoded by sitABCD and mntH. In symbiosis, sitABCD and mntH were expressed throughout nodules and also strongly induced in Mn(2+) -limited cultures of free-living cells. Growth of a sitA mntH double mutant was severely reduced under Mn(2+) limitation and sitA and mntH single mutants were more sensitive to oxidative stress. The double sitA mntH mutant of R. leguminosarum was unable to fix nitrogen (Fix(-) ) with legumes belonging to the galegoid clade (Pisum sativum, Vicia faba and Vicia hirsuta)...
