Change detection versus change localization for faces, houses, and words

The other-race effect (ORE) is a well-known phenomenon in which people discriminate and recognize faces from their ethnic group more accurately than faces from other ethnic groups. Holistic processing, or the mandatory tendency to process all parts of an object together, has been proposed as an explanation for the ORE. According to the holistic perspective of the ORE, other-race faces might be subject to weaker...

From Perugino to Picasso: Holistic processing of faces in paintings

Faces are generally assumed to be processed holistically, that is, features are represented in an integrated fashion. Similarly, pictorial representations of faces (e.g., drawings) have been shown to elicit holistic processing. Some researchers, however, have contested the concept of holistic face processing, suggesting that the perception of a face is no more than the sum of individual face parts. In the prese...

The mechanisms supporting holistic perception of words and faces are not indepe...

The question of whether word and face recognition rely on overlapping or dissociable neural and cognitive mechanisms received considerable attention in the literature. In the present work, we presented words (aligned or misaligned) superimposed on faces (aligned or misaligned) and tested the interference from the unattended stimulus category on holistic processing of the attended category. In Experiment 1, we f...

The relation between holistic processing as measured by three composite tasks a...

We investigated the relationship between holistic processing and face processing using a latent variables approach. Three versions of the composite paradigm were used to measure holistic processing: Vanderbilt Holistic Face Processing Test, a sequential composite matching task, and a simultaneous composite matching task. Three tasks were used to measure face perception and face memory abilities respectively. We...

The Body mass index in patients with Multiple Sclerosis: A meta-analysis

This article is an update of a systematic review and meta-analysis related to BMI levels in patients with multiple sclerosis. 31 studies published between 1997 and 2020 were collected. The main objective of this meta-analysis was to compare BMI levels between patients with MS and healthy controls. We conclude that BMI appears to be significantly lower in patients with MS, compared to healthy controls. However, ...

Validation and Extension of a Logistic Regression Model Developed from a Cohort...

Cytotoxic effects of crotamine are mediated through lysosomal membrane permeabi...

Crotamine, one of the main toxic components of Crotalus durissus terrificus venom, is a small non-enzymatic basic polypeptide, which causes hind limb paralysis and necrosis of muscle cells. It is well-known that several toxins penetrate into the cytosol through endocytosis, although in many cases the mechanism by which this occurs has not been fully investigated. Recently, using low concentrations of crotamine,...

Thermal evaluation of MAG/TIG welding using numerical extension tool

The manufacturing processes involving thermal transitions have been more used in industries nowadays, being the welding one of the most widely used. The requirement to design and predict adverse conditions are fundamental to the development of any mechanical project. As a result, the market needs have motivated the companies to find faster and more effective solutions, being one of a recent tools an ACT (Ansys ...

Cross-leg flap after postraumatic osteomyelitis defect: A last resource for lim...

We report the case of a patient with a tibial shaft fracture occurring through a chronic posttraumatic osteomyelitis site with significant soft tissue defect. The bone and soft tissue reconstruction procedures are described with a cross-leg fasciocutaneous flap performed as a last resource after previous rotated muscle flap partial failure. Pre-operative CT angiography, to rule outaxial vessel damage and periph...

Extensive skin necrosis after periprosthetic knee infection: a case that highli...

We describe a case of a patient with atrial fibrillation, anticoagulated with dabigatran, that developed severe knee skin necrosis in the setting of an acute periprosthetic knee infection, after initiating low-molecular-weight heparin. A wide range of etiology hypotheses was discussed within a multidisciplinary team. The complex approach consisted of treating the underlying infection, multiple types of soft-tis...
