Although differences in selective attention skills have been identified in children from lower compared to higher socioeconomic status (SES) backgrounds, little is known about these differences in early childhood, a time of rapid attention development. The current study evaluated the development of neural systems for selective attention in children from lower SES backgrounds. Event-related potentials (ERPs) were acquired from 33 children from lower SES and 14 children from higher SES backgrounds during a dichotic listening task...

The study of protein phosphorylation is critical for the advancement of our understanding of cellular responses to external and internal stimuli. Phosphorylation, the addition of phosphate groups, most often occurs on serine, threonine, or tyrosine residues due to the action of protein kinases. This structural change causes the protein to become activated (or deactivated) and enables it in turn to initiate the phosphorylation of other proteins in a cascade, eventually causing cell-wide changes such as apoptosis, cell differentiation, and growth (among others)...

RNAs that are transcribed and self-assemble within living cells are valuable tools for regulating and organizing cellular activities. Riboregulators, in particular, have been widely used for modulating translation and transcription in response to cognate transactivating or trigger RNAs, enabling cells to evaluate logic operations and to respond to environmental cues. Herein we detail a set of methods for the rapid construction and testing of prokaryotic riboregulators in Escherichia coli. These methods enable construction of dozens of riboregulator plasmids at the same time without the use of restriction enzymes...

BACKGROUND: Anandamide (AEA)-dependent signaling is regulated by the catabolic enzyme fatty acid amide hydrolase (FAAH). Several lines of evidence have demonstrated that FAAH and AEA are involved in the behavioral effects of alcohol. Therefore, we investigated whether a selective FAAH inhibitor, URB597 (cyclohexylcarbamic acid 3'-[aminocarbonyl]-[1,1'-biphenyl]-3-yl ester), altered alcohol intake in mice in a voluntary alcohol drinking model. METHODS: Mice, subjected to 3 weeks of chronic intermittent access (IA) in a two-bottle choice paradigm with 24-h access every other day, developed rapid escalation of alcohol intake and high preference...

The control of nucleation in crystallization processes is a challenging task due to the often lacking knowledge on the process kinetics. Inflexible (predetermined) control strategies fail to grow the nucleated crystals to the desired quality because of the variability in the process conditions, disturbances, and the stochastic nature of crystal nucleation. Previously, the concept of microwave assisted direct nucleation control (DNC) was demonstrated in a laboratory setup to control the crystal size distribution in a batch crystallization process by manipulating the number of particles in the system...

To cope with environmental stresses, bacteria have evolved various strategies, including the general stress response (GSR). GSR is governed by an alternative transcriptional sigma factor named σ(S) (RpoS) that associates with RNA polymerase and controls the expression of numerous genes. Previously, we have reported that posttranslational regulation of σ(S) in the aquatic bacterium Shewanella oneidensis involves the CrsR-CrsA partner-switching regulatory system, but the exact mechanism by which CrsR and CrsA control σ(S) activity is not completely unveiled...

Crocodilians are regarded as possessing a powerful immune system. However, the composition and action of crocodilian immune system has remained unclear until now. Cathelicidins, the principal family of host defense peptides, play pivotal roles in vertebrate immune defense against microbial invasions. However, cathelicidins from crocodilians have not been extensively studied to date. In the present study, six novel cathelicidins (As-CATH1~6) were identified and characterized from the endangered Chinese Alligator ( Alligator sinensis )...

The goal of this work is to develop an innovative method that combines bioprinting and endoscopic imaging to repair tympanic membrane perforations (TMPs). TMPs are a serious health issue because they can lead to both conductive hearing loss and repeated otitis media. TMPs occur in 3 to 5% of cases after ear tube placement as well as in cases of acute otitis media (the second most common infection in pediatrics), chronic otitis media with or without cholesteatoma, or as a result of barotrauma to the ear. About 55,000 tympanoplasties, the surgery performed to reconstruct TMPs, are performed every year and the commonly used cartilage grafting technique has a success rate between 43% to 100%...

Glycogen accumulation in the central nervous system of patients with classical infantile onset Pompe disease (IOPD) has been a consistent finding on the few post-mortems performed. While delays in myelination and a possible reduction in processing speed have previously been noted, it has only been recently that the potential for clinically significant progressive white matter disease has been noted. The limited reports thus far published infer that in some IOPD patients, this manifests as intellectual decline in the second decade of life...

The ErbB family of receptor tyrosine kinases comprises four members: epidermal growth factor receptor (EGFR/ErbB1), human EGFR 2 (HER2/ErbB2), ErbB3/HER3, and ErbB4/HER4. The first two members of this family, EGFR and HER2, have been implicated in tumorigenesis and cancer progression for several decades, and numerous drugs have now been approved that target these two proteins. Less attention, however, has been paid to the role of this family in mediating cancer cell survival and drug tolerance. To better understand the complex signal transduction network triggered by the ErbB receptor family, we built a computational model that quantitatively captures the dynamics of ErbB signaling...

The involvement of the reticular formation (RF) in the transmission and modulation of nociceptive information has been extensively studied. The brainstem RF contains several areas which are targeted by spinal cord afferents conveying nociceptive input. The arrival of nociceptive input to the RF may trigger alert reactions which generate a protective/defense reaction to pain. RF neurons located at the medulla oblongata and targeted by ascending nociceptive information are also involved in the control of vital functions that can be affected by pain, namely cardiovascular control...

When identical stimuli are presented in rapid temporal succession, neural responses to the second stimulation are often weaker than that observed for the first. This phenomenon is termed sensory gating and is believed to be an adaptive feature that helps prevent higher-order cortical centers from being flooded with unnecessary information. Recently, sensory gating in the somatosensory system has been linked to deficits in tactile discrimination. Additionally, studies have linked poor tactile discrimination with impaired walking and balance in individuals with multiple sclerosis (MS)...

Primary infection of a plant with a pathogen that causes high accumulation of salicylic acid in the plant typically via a hypersensitive response confers enhanced resistance against secondary infection with a broad spectrum of pathogens, including viruses. This phenomenon is called systemic acquired resistance (SAR), which is a plant-priming for adaption to repeated biotic stress. However, the molecular mechanisms of SAR-mediated enhanced inhibition, especially of virus infection, remain unclear. Here, we show that SAR against cucumber mosaic virus (CMV) in tobacco plants (Nicotiana tabacum) involves a calmodulin-like protein, rgs-CaM...

Identification of a novel post-translational modification (PTM) for a target protein, defining its physiologic role, and studying its potential crosstalk with other PTMs is a challenging process. A set of highly sensitive tools termed Signal-Seeker kits was developed, which enables rapid and simple detection of post-translational modifications on any target protein.  The methodology for these tools utilizes affinity purification of modified proteins from a cell or tissue lysate and immunoblot analysis. These tools utilize a single lysis system that is effective at identifying endogenous, dynamic PTM changes, as well as the potential crosstalk between PTMs...

Over the past few decades, there has been tremendous interest in developing biosensing systems that combine high sensitivity and specificity with rapid sample-to-answer times, portability, low-cost operation, and ease-of-use. Miniaturizing the biosensor dimensions into the nanoscale has been identified as a strategy for addressing the functional requirements of point-of-care and wearable biosensors. However, it is important to consider that decreasing the critical dimensions of biosensing elements impacts the two most important performance metrics of biosensors: limit-of-detection and response time...

During the last two decades the production of pharmaceutical proteins in plants evolved from proof of concept to established technology adopted by several biotechnological companies. This progress is particularly based on intensive research starting stable genetic transformation and moving to transient expression. Due to its advantages in yield and speed of protein production transient expression platforms became leading plant-based manufacturing technology. Current transient expression methods rely on Agrobacterium-mediated delivery of expression vectors into plant cells...
