Interactions between plants and phytophagous insects play an important part in shaping the biochemical composition of plants. Reciprocally plant metabolites can influence major life history traits in these insects and largely contribute to their fitness. Plant rhizospheric microorganisms are an important biotic factor modulating plant metabolites and adaptation to stress. While plant-insects or plant-microorganisms interactions and their consequences on the plant metabolite signature are well-documented, the impact of soil microbial communities on plant defenses against phytophagous insects remains poorly known...

Processing of hydrogels represents a main challenge for the prospective application of additive manufacturing (AM) to soft tissue engineering. Furthermore, direct manufacturing of tissue precursors with a cell density similar to native tissues has the potential to overcome the extensive in vitro culture required for conventional cell-seeded scaffolds seeking to fabricate constructs with tailored structural and functional properties. In this work, we present a simple AM methodology that exploits the thermoresponsive behavior of a block copolymer (Pluronic®) as a means to obtain good shape retention at physiological conditions and to induce cellular alignment...

tRNA molecules undergo extensive modifications during their maturation process and these modifications play important cellular roles. TrmL is a tRNA-modification enzyme that catalyzes the transfer of a methyl group to the 2' hydroxyl group of the pyrimidines at the wobble position 34 in two tRNA(L)(eu) isoacceptors, but the mechanism remains elusive. In this study, we determined the crystal structure of TrmL from Thermus Thermophilus (TtTrmL) to 1.7 Å. The enzyme contains only the conserved minimal SPOUT fold, but displays distinct biochemical behaviors from its Escherichia coli counterpart EcTrmL...

OBJECTIVE: Washington State mandated seven hospital "best practices" in July 2012, several of which may affect ED opioid prescribing and provide a policy template for addressing the opioid prescription epidemic. We tested the hypothesis that the mandates would reduce opioid dispensing after an ED visit. We further assessed for a selective effect in patients with prior risky or chronic opioid use. METHODS: We performed a retrospective, observational analysis of ED visits by Medicaid fee-for service beneficiaries in Washington State, between July 1, 2011 to June 30, 2013...

Drosophila buzzatii and D. koepferae are sibling cactophilic species. The former breeds primarily on prickly pears (genus Opuntia) whereas the latter breeds on columnar cacti of the genera Cereus and Trichocereus, although with certain degree of niche overlapping. We examined the interspecific differences in diurnal temporal patterns of adult emergence from puparia and evaluated whether this behavior is affected by rearing in the different cactus hosts available in nature. We detected important host-dependent genetic variation for this trait differentially affecting the emergence schedule of these species...

AIMS AND OBJECTIVES: This narrative literature review aimed to examine empirical studies of MS and MT carried out with preterm infants and their parents published from 2010 to 2015. BACKGROUND: Prematurity constitutes a global health problem that can impact the development of the preterm infant and the well-being of the parents. Music-based interventions may benefit the infant, parents, and their relationship. In our review, we distinguished between musical stimulation (MS) and music therapy (MT), as we found no previous studies that had made this distinction...

Learning to associate a stimulus with reinforcement causes plasticity in primary sensory cortex. Neural activity caused by the associated stimulus is paired with reinforcement, but population analyses have not found a selective increase in response to that stimulus. Responses to other stimuli increase as much as, or more than, responses to the associated stimulus. Here, we applied population analysis at a new time point, and additionally evaluated whether cholinergic receptor blockers interacted with the plastic changes in cortex...

BACKGROUND: Alternative splicing mediated by RNA-binding proteins (RBPs) is emerging as a fundamental mechanism for the regulation of gene expression. Alternative splicing has been shown to be a widespread phenomenon that facilitates the diversification of gene products in a tissue specific manner. Although defects in alternative splicing are rooted in many neurological disorders, only a small fraction of splicing factors have been investigated in detail. RESULTS: We find that the splicing factor Caper is required for the development of multiple different mechanosensory neuron subtypes at multiple life stages in Drosophila melanogaster...

Two-stage exchange with antibiotic-loaded bone cement spacers remains the gold standard for chronic periprosthetic joint infection(PJI). Rifampicin is highly efficient on stationary-phase staphylococci in biofilm; however, its addition to PMMA to manufacture spacers prevents polymerization and reduces mechanical properties. Isolation of rifampicin during polymerization by microencapsulation could allow manufacturing rifampicin-loaded bone cement maintaining elution and mechanical properties. Microcapsules of rifampicin with alginate, polyhydroxybutyratehydroxyvalerate (PHBV), ethylcellulose and stearic acid (SA) were synthesized...

Existing studies on the mechanism of cell volume regulation are mainly relevant to ion channels and osmosis in extracellular fluid. Recently, accumulating evidence has shown that cellular mechanical microenvironment also influences the cell volume. Herein, we investigated the regulation of substrate stiffness on the cell volume homeostasis of MCF-7 cells and their following migration behaviors. We found that cell volume increases with increasing substrate stiffness, which could be affected by blocking the cell membrane anion permeability and dopamine receptor...

Mountain pine beetles (MPB, Dendroctonus ponderosae Hopkins) are aggressive insects attacking Pinus host trees. Pines use defensive resin to overwhelm attackers, creating an Allee effect requiring beetles to attack en masse to successfully reproduce. MPB kill hosts, leaving observable, dying trees with red needles. Landscape patterns of infestation depend on MPB dispersal, which decreases with host density. Away from contiguously impacted patches (low beetle densities), infestations are characterized by apparently random spots (of 1-10 trees)...

Pregnant women with opioid use disorder can be treated with methadone, buprenorphine, or naltrexone to reduce opioid use and improve retention to treatment. In this review, we compare the pregnancy outcomes of methadone, buprenorphine, and naltrexone in clinical trials and discuss the potential behavioral and developmental effects of these agents seen in offspring in animal studies. Important clinical considerations in the management of opioid use disorder in pregnant women and their infants are also discussed...

Many studies have shown that variation in transcription is associated with changes in behavioral state, or with variation within a state, but little has been done to address if the same genes are involved in both. Here we investigate the transcriptional basis of variation in parental provisioning using two species of burying beetle, Nicrophorus orbicollis and Nicrophorus vespilloides. We used RNA-seq to compare transcription in parents that provided high amounts of provisioning behavior versus low amounts in males and females of each species...

INTRODUCTION: Tobacco cessation is the most important, cost-effective preventive maintenance that clinicians can offer study participants who use tobacco. There is lack of preparedness among primary care physicians in delivering cessation interventions. There are also limited studies which record the effectiveness of cessation interventions in the Indian context. This study is designed to evaluate the effectiveness of brief and intensive tobacco cessation interventions delivered by trained primary care providers in two states of India...
