A new species of (Monimiaceae, Laurales) from the Quadrilátero Ferrífero, Brazil.

Monimiaceae comprises approximately 26 genera and 250 species, with a pantropical distribution, predominantly occurring in humid forests. In Brazil, it is represented by five genera and 47 species, most of which are found in the Atlantic Forest, particularly in dense ombrophilous forest. Nevertheless, studies on this family in other biomes and vegetation types in Brazil are still scarce.

The first notosuchian crocodyliform from the Araçatuba Formation (Bauru Group, Paraná Basin), and diversification of sphagesaurians.

The mesoeucrocodylian record from the Bauru Group (Paraná Basin, Brazil) comes from three formations: Adamantina (Late Turonian-Early Maastrichtian), Presidente Prudente (Early Campanian-Early Maastrichtian) and Marília (Maastrichtian). These records are restricted to the Early Coniacian-Early Maastrichtian. Here, we report a new crocodyliform record from the Bauru Group, which was the first of the Araçatuba Formation, from a new locality of Coronel Goulart district, in Álvares Machado municipality.

Seasonal Patterns of Host Plant Use in an Assemblage of Heliconiini Butterflies (Lepidoptera: Nymphalidae) in a Neotropical forest.

Insect-plant interactions involve physiological adaptations by insects to secondary metabolic compounds synthetized by host plants, which are considered essential for the determination of resources partitioning of these insects. Data on such phenomena are important to understand evolutionary and ecological processes. However, climatic factors also seem to play a key role in affecting these patterns.

Overview: Adhesive dentistry has undergone major transformations within the last 20 years. New dental adhesives and composite resins have been launched with special focus on their user-friendliness by reducing the number of components and/or clinical steps.

The volition, the mode of movement selection and the readiness potential.

A growing body of evidence suggests that the mode of movement selection is relevant for the readiness potential, namely, internal (or free) selection of movements is associated with increased readiness potential amplitudes compared to predetermined or externally guided selection. It is little acknowledged, however, that this finding may be ascribed to the different expression of volition (i.e.

The roles of hybridization and habitat fragmentation in the evolution of Brazil's enigmatic longwing butterflies, Heliconius nattereri and H. hermathena.

Background: Heliconius butterflies are widely distributed across the Neotropics and have evolved a stunning array of wing color patterns that mediate Müllerian mimicry and mating behavior. Their rapid radiation has been strongly influenced by hybridization, which has created new species and allowed sharing of color patterning alleles between mimetic species pairs. While these processes have frequently been observed in widespread species with contiguous distributions, many Heliconius species inhabit patchy or rare habitats that may strongly influence the origin and spread of species and color patterns.

Age and Disease have a Distinct Influence on Postural Balance of Patients with COPD.

The postural imbalance is an extra-pulmonary condition, associated with chronic obstructive pulmonary disease (COPD). COPD affects older individuals and it is unclear whether balance abnormalities can be described as pathophysiological mechanism or aging. The present study aimed to evaluate the influence of age or disease on postural balance of patients with COPD.

Disruption of volitional control in obsessive-compulsive disorder: Evidence from the Bereitschaftspotential.

In the context of controversies involving possible abnormalities in the volition and action control in obsessive-compulsive disorder (OCD), the current study examined electroencephalographic correlates of automatic and volitional brain processes involved in the genesis of spontaneous movements in individuals diagnosed with OCD. For this, the amplitudes of early and late Bereitschaftspotential (early BP and late BP) from 12 patients and 12 controls were obtained while they performed spontaneous button presses under different levels of volitional experience. In the first condition, participants were distracted from their motor actions by a mental task (automatic condition) and in the second condition they were instructed to attending to their own intention to move (willed condition).

Dupuytren's disease: where do we stand?

Dupuytren's disease is a fibroproliferative disease that involves collagen deposition, leading to hand contractures that ultimately affect hand mobility and grip strength.It is a benign disorder but can cause high morbidity by limiting daily activities.Many factors have been proposed for its aetiology: namely genetics, smoking, alcohol intake and diabetes.

Coronary Sinus Stenosis With Right Coronary Artery to Coronary Sinus Fistula.

Coronary artery fistula is a rare congenital cardiac anomaly. We report a 34-year-old woman who presented with a recurrent large pericardial effusion during pregnancy. She was found to have a right coronary artery to coronary sinus fistula.

Photobiomodulation Improved the First Stages of Wound Healing Process After Abdominoplasty: An Experimental, Double-Blinded, Non-randomized Clinical Trial.

Background: Photobiomodulation is widely studied for its potential benefits in the wound healing process. Numerous scientific studies have highlighted its effect on various phases of wound repair, but clinical validations are few. This comparative trial aims to evaluate the influence of photobiomodulation on the post-abdominoplasty healing process.

Breast Reduction: The Superolateral Dermoglandular Pedicle Revisited.

Background: Breast hypertrophy, generally found in association with ptosis, is a common problem in postadolescent women. Beyond the psychological burden of excessively heavy, droopy breasts, physical symptoms compound the condition, with neck, shoulder and back pain. Reduction mammaplasty is one of the most common cosmetic operations, especially to improve patient's musculoskeletal symptoms, with proven benefits in patient satisfaction and self-esteem postoperatively.

Young and older adults adapt automatic postural responses equivalently to repetitive perturbations but are unable to use predictive cueing to optimize recovery of balance stability.

Processing of contextual cues has been proposed to modulate the generation of automatic postural responses to unanticipated balance perturbations. In this investigation, we compared young and older individuals in responses to sudden rotations of the support base inducing either planti- or dorsiflexion of the ankles. Assessment was made in conditions resulting from the combination of visual directional cueing of the forthcoming platform rotation, and block versus random sequences of platform rotation directions.

The effect of conscious intention to act on the Bereitschaftspotential.

The current study investigated the effect of conscious intention to act on the Bereitschaftspotential. Situations in which the awareness of acting is minimally expressed were generated by asking 16 participants to press a button after performing a mental imagery task based on animal pictures (automatic condition). The affective responses induced by the pictures were controlled by selecting the animals according to different valences, threatening and neutral.

All children were submitted to dynamic posturography using a modified sensory organization test, using four sensory conditions: combining stable or sway referencing platform with eyes opened, or closed.

Comparative analysis of the electroencephalogram in patients with Alzheimer's disease, diffuse axonal injury patients and healthy controls using LORETA analysis.

Unlabelled: Alzheimer's disease (AD) is a dementia that affects a large contingent of the elderly population characterized by the presence of neurofibrillary tangles and senile plaques. Traumatic brain injury (TBI) is a non-degenerative injury caused by an external mechanical force. One of the main causes of TBI is diffuse axonal injury (DAI), promoted by acceleration-deceleration mechanisms.

Distal phalanx amputation with delayed presentation and successful reconstruction with reposition and flap after 2 weeks.

Traumatic finger amputations are common, causing significant functional and cosmetic deficits. Microsurgical replantation techniques are the mainstay of treatment for most such injuries although they require adequate conservation of the amputated segment for a successful result. In distal finger amputations, replantation is the procedure of choice, as long as the amputated fragment is viable.

Validity of periodontitis screening questions in a Brazilian adult population-based study.

Population-based studies assessing self-reported periodontal questions in low-income countries are lacking, and therefore we aimed to assess the accuracy of self-reported periodontal items in Brazil. One thousand one hundred and forty adults from Florianópolis, Brazil, had their periodontium clinically examined, and responded to the following self-reported items on periodontal conditions: Question (Q)1, Do you have any wobbly teeth?; Q2, Do your gums usually bleed?; and Q3, Has your dentist ever told you that you have gum disease? Periodontitis was defined as: a. ≥ 6.
