Aim: The present study aims to verify the information processing in athletes through electroencephalography, analyze cortical areas responsible for cognitive functions related to attentional processing of visual stimuli, and investigate motor activity's influence on cognitive aspects. Additionally, we aimed to analyze the acute effect of physical exercise after the high-intensity anaerobic effort, evaluating how a short-duration Wingate test influences cortical activity and attentional processing immediately following exertion.

Materials And Methods: The sample consisted of 29 subjects, divided into an experimental group (n = 13 modern pentathlon athletes) and a control group (n = 16 non-athletes).

Objective: To carry out a critical review of the literature on the use of race, color, and ethnicity in the field of public health dentistry.

Methods: A literature search was conducted in MEDLINE via PubMed for articles published between 2014 and 2019. Using a data extraction form, we collected information on (1) bibliographic characteristics of the selected papers; (2) race, color, and ethnicity of the study participants and their sociodemographic profiles; and (3) the extent to which the original publications followed the recommendations by Kaplan and Bennett (2003) on the use of race, color, or ethnicity in biomedical research.

Leakage of stomal effluent is considered by people living with a stoma to be the key factor that negatively impacts their quality of life (QoL). This non-randomised pilot study evaluated the performance of a new stoma appliance, Flexima Active O Convex in 40 ostomy patients with a flat, flush or slightly retracted stoma over a 14-day period. Leakage was reported for the wear time of each pouch by the patients.

Mutations in nebulin, a giant muscle protein with 185 actin-binding nebulin repeats, are the major cause of nemaline myopathy in humans. Nebulin sets actin thin filament length in sarcomeres, potentially by stabilizing thin filaments in the I-band, where nebulin and thin filaments coalign. However, the precise role of nebulin in setting thin filament length and its other functions in regulating power output are unknown.

Photophysical and photochemical measurements have been made on a series of novel alpha octa(alkyl-substituted) silicon, zinc and palladium phthalocyanines for which the synthesis is outlined. Fluorescence quantum yields and lifetimes, triplet quantum yields and lifetimes and singlet delta oxygen quantum yields were measured in 1% v/v pyridine in toluene. The effects of varying central atom and addition of alkyl substituents relative to unsubstituted parent molecules, zinc phthalocyanine (ZnPc) and silicon phthalocyanine (SiPc), are discussed.

Background: Developmental programs are implemented by regulatory interactions between Transcription Factors (TFs) and their target genes, which remain poorly understood. While recent studies have focused on regulatory cascades of TFs that govern early development, little is known about how the ultimate effectors of cell differentiation are selected and controlled. We addressed this question during late Drosophila embryogenesis, when the finely tuned expression of the TF Ovo/Shavenbaby (Svb) triggers the morphological differentiation of epidermal trichomes.

Msx homeogenes play an important role in the epithelial-mesenchymal interactions leading development. Msx1 is relevant for dental and craniofacial morphogenesis, as suggested by phenotypes of Msx1 mutations in human and Msx1 KO mice. Our group showed that Msx1 gene expression can be regulated by a bidirectional transcription generating long noncoding antisense (AS) RNA the expression which is linked to the Msx1 sense (S) RNA level.

The terminal differentiation of epithelial cells involves changes in the apical compartment, including remodeling of the cytoskeleton and junctions to modify its three-dimensional organization. It also often triggers the building of specialized extracellular matrices, the function of which remains poorly understood. Hundreds of extracellular matrix proteins expressed in a variety of epithelia possess a conserved region called the zona pellucida-domain (ZP domain).

The zona pellucida domain (ZPD) defines a conserved family of membrane-anchored matrix proteins that are, as yet, poorly characterized with respect to their functions during development. Using genetic approaches in flies, we show here that a set of eight ZPD proteins is required for the localized reorganization of embryonic epidermal cells during morphogenesis. Despite varying degrees of sequence conservation, these ZPD proteins exert specific and nonredundant functions in the remodeling of epidermal cell shape.

Ligand-dependent corepressor LCoR interacts with the progesterone receptor (PR) and estrogen receptor ERalpha in the presence of hormone. LCoR contains tandem N-terminal PXDLS motifs that recruit C-terminal-binding protein (CtBP) corepressors as well as a C-terminal helix-turn-helix (HTH) domain. Here, we analyzed the function of these domains in coregulation of PR- and ERalpha-regulated gene expression.

Ligand-dependent corepressor LCoR was identified as a protein that interacts with the estrogen receptor alpha (ERalpha) ligand binding domain in a hormone-dependent manner. LCoR also interacts directly with histone deacetylase 3 (HDAC3) and HDAC6. Notably, HDAC6 has emerged as a marker of breast cancer prognosis.

The Msx1 homeogene plays an important role in epithelial-mesenchymal interactions leading organogenesis. Msx1 gene is submitted to bidirectional transcription generating a long non-coding antisense (AS) RNA potentially involved in Msx1 expression regulation. RT-Q-PCR and RNA-FISH studies indicated that transient overexpression of the Msx1 AS transcript in 705IC5 mouse odontoblasts decreased the abundance of endogenous Msx1 S mRNA at the post-transcriptional level.

Coxiella burnetii is an intracellular bacterium that causes a worldwide zoonosis, the Q fever. Currently, to diagnose the infection in ruminants, whole cell antigens-based ELISAs are used. In this study a heat shock protein, the HspB, was evaluated for its ability to be recognized by the goat immune system and its capacity to sign a stage of infection.

Msx homeogenes play an important role in epithelial-mesenchymal interactions leading development. Msx1 is relevant for dental and craniofacial morphogenesis, as suggested by phenotypes of Msx1 mutations in human and Msx1 KO mice. During adulthood, Msx1 is still expressed in the skeleton where its role is largely unknown.

Many genes that interact in a complex and interdependent manner participate in the development of the craniofacial complex. One of them, the Msxl homeobox gene, a transcription factor, is expressed from early developmental stages to adulthood in accordance with specific spatio-temporal patterns. When it is suppressed, transgenic mice exhibit craniofacial abnormalities that demonstrate what is its function in normal growth, just as it has been shown that certain Msxl mutations in humans are commonly associated with tooth agenesis.

It is well established that developmental programs act during embryogenesis to determine animal morphogenesis. How these developmental cues produce specific cell shape during morphogenesis, however, has remained elusive. We addressed this question by studying the morphological differentiation of the Drosophila epidermis, governed by a well-known circuit of regulators leading to a stereotyped pattern of smooth cells and cells forming actin-rich extensions (trichomes).

Members of the nuclear receptor superfamily are ligand-regulated transcription factors that are composed of a series of conserved domains. These receptors are targets of a wide range of lipophilic signaling molecules that modulate many aspects of physiology and metabolism. Binding of cognate ligands to receptors induces a conformational change in the ligand binding domain (LBD) that creates a pocket for recruitment of coregulatory proteins, which are essential for ligand-dependent regulation of transcription.

LCoR (ligand-dependent corepressor) is a transcriptional corepressor widely expressed in fetal and adult tissues that is recruited to agonist-bound nuclear receptors through a single LXXLL motif. LCoR binding to estrogen receptor alpha depends in part on residues in the coactivator binding pocket distinct from those bound by TIF-2. Repression by LCoR is abolished by histone deacetylase inhibitor trichostatin A in a receptor-dependent fashion, indicating HDAC-dependent and -independent modes of action.
