Safvet Ors
To determine the warping angle of the costal cartilage in vivo. A nasal framework reconstruction with a rib graft was performed in a total of 130 patients. After the cartilage specimens were prepared, the remaining grafts were used for the experimental study. The angle of warping in all grafts was measured at 0, 30, and 60 minutes, after 24 hours and after one week. In this study, 8 subgroups of graft thicknesses from central and peripheral groups, which were determined according to the perichondral distance of the grafts, were evaluated, and the warping angles of a total of 48 osteochondral and chondral grafts were individually measured...

BACKGROUND: Regular physical activity (PA) is beneficial for physical and psychological well-being, yet many people do not achieve these health benefits due to irregular PA participation which is also known as fluctuation. Limited attention has been given to the phenomenon of fluctuation in the PA behaviour literature. OBJECTIVE: The aim of this review was to explore and to map definitions, measurements, behavioural evidence, and factors related to PA fluctuation...

Projection and backprojection operations are essential in a variety of image reconstruction and physical correction algorithms in CT. The distance-driven (DD) projection and backprojection are widely used for their highly sequential memory access pattern and low arithmetic cost. However, a typical DD implementation has an inner loop that adjusts the calculation depending on the relative position between voxel and detector cell boundaries. The irregularity of the branch behavior makes it inefficient to be implemented on massively parallel computing devices such as graphics processing units (GPUs)...

Aasef G Shaikh, Stewart A Factor, Jorge Juncos
Background and objectives: Slowed and curved rapid eye movements, saccades, are the well-known features of progressive supranuclear palsy (PSP). We hypothesized that the saccades in PSP are not only slow and curved, but they are also irregular and have timing deficits. Methods: We tested this hypothesis in 12 patients with PSP by measuring vertical and horizontal visually guided saccades using a limbus tracker. Results: Both, horizontal and vertical saccades were slow and had irregular trajectory and velocity profiles, but deficits were much more robust in vertical saccades...

INTRODUCTION: Abdominal hypopressive gymnastics appeared as an alternative to traditional abdominal exercises to promote abdominal muscles strength without overloading the pelvic floor muscles (PFM). To determine the activation level of abdominal muscles and PFM and the posture influence in the level of activation in these muscles during abdominal hypopressive gymnastics, we used surface electromyography in young and healthy multipara women. METHODS: This is an observational study with eutrophic nulliparous women aged between 18 and 35 years, with abdominal skinfold less than or equal to 3 cm and active or irregularly active physical activity...

We examined the hypothesis that skilled performance is monitored on the basis of fluency, where fluency is operationally defined as temporal regularity or rhythmicity rather than speed. Since error is often associated with variable timing, we tested the possibility that people use varied timing as a metacognitive cue. Using a sequential counting task, which may be representative of the broader class of skilled, multi-step tasks, we found that shifting between irregular and regular timing led to greater confidence ratings when the timing associated with the task was regular...

Xue Zhao, Yun Bai, Tong Xing, Xing-Lian Xu, Guanghong Zhou
The functionality of pale, soft, exudative (PSE)-like chicken protein was improved by isoelectric solubilization/precipitation (ISP) treatment. PSE-like chicken proteins were solubilized at an acidic pH 3.5 or an alkaline pH 11.0, followed by precipitating at pH 5.5 and 6.2. PSE-like meat paste was treated as control (CON). Precipitated at pH 6.2 led to a more elastic gel than at pH 5.5. Water distribution of ISP-isolated protein was affected by precipitation pH. More tryptophan residues exposed and -SH was partially oxidized to disulfide bond after ISP treatment, which led to large aggregates formation and higher viscosity of ISP isolated proteins than of CON...

Horizontal gene transfer (HGT) is an important mechanism in the evolution of many living organisms particularly in Prokaryotes where genes are frequently dispersed between taxa. Although, HGT has been reported in Eukaryotes, its accumulative effect and its frequency has been questioned. Arbuscular mycorrhizal fungi (AMF) are an early diverged fungal lineage belonging to phylum Glomeromycota, whose phylogenetic position is still under debate. The history of AMF and land plant symbiosis dates back to at least 460 million years ago...

Chronic lung allograft dysfunction continues to be the main contributor to poor long-term allograft survival after lung transplantation. The restrictive phenotype of chronic lung allograft dysfunction carries a particularly poor prognosis. Little is known about the pathogenetic mechanisms involved in restrictive chronic lung allograft dysfunction. In this study, we performed histomorphological and immunohistochemical analysis of restrictive chronic lung allograft dysfunction lungs. Explant lung tissue from 21 restrictive chronic lung allograft dysfunction patients was collected and histopathologic patterns of rejection, fibrosis and vascular changes were scored after routine histochemical stains and additional immunohistochemistry for endothelial markers and C4d...

The dropseed gall-forming nematode, Afrina sporoboliae sp. n., is described from seed galls of Sporobolus cryptandrus (Poaceae: Chloridoideae: Sporobolinae) collected in Idaho, USA. This is the third report of an Afrina species in North America and the first report of this genus in a natural plant population on this continent. Morphological, morphometric, and molecular analyses placed this nematode in genus Afrina and demonstrated that it differs from Af. hyparrheniae and Af. spermophaga by having longer body and stylet lengths for females and males, and from Af...

Ryan P Blything, Ben Ambridge, Elena V M Lieven
This study adjudicates between two opposing accounts of morphological productivity, using English past-tense as its test case. The single-route model (e.g., Bybee & Moder, ) posits that both regular and irregular past-tense forms are generated by analogy across stored exemplars in associative memory. In contrast, the dual-route model (e.g., Prasada & Pinker, ) posits that regular inflection requires use of a formal "add -ed" rule that does not require analogy across regular past-tense forms. Children (aged 3-4; 5-6; 6-7; 9-10) saw animations of an animal performing a novel action described with a novel verb (e...

Identification of carotid artery atherosclerosis is conventionally based on measurements of luminal stenosis and surface irregularities using in vivo imaging techniques including sonography, CT and MR angiography, and digital subtraction angiography. However, histopathologic studies demonstrate considerable differences between plaques with identical degrees of stenosis and indicate that certain plaque features are associated with increased risk for ischemic events. The ability to look beyond the lumen using highly developed vessel wall imaging methods to identify plaque vulnerable to disruption has prompted an active debate as to whether a paradigm shift is needed to move away from relying on measurements of luminal stenosis for gauging the risk of ischemic injury...
