These results emphasize the importance of evaluating potential therapeutic compounds for neuroprotection in multiple models using elongated treatment paradigms for an accurate assessment of efficacy.Objective This study examined acute findings and long-term outcome trajectories between birth and adolescence in children with prenatal opiate exposure. Study design Ninety children (45 opiate-exposed, 45 non-exposed) completed assessments between 1 month and 15 years of age. Outcome variables (medical, anthropomorphic, developmental, and behavioral) were analyzed at individual time points and using longitudinal statistical modeling. Results Opiate-exposed infants displayed transient neurologic findings, but no substantial signs or symptoms long term. There were no group differences in growth, cognitive functioning, or behavior at individual time periods; however, the trajectories of outcomes using longitudinal analyses adjusting for variables known to impact outcome demonstrated increased deficits among opiate-exposed children over time with regards to weight, head circumference, cognitive functioning, and behavior. Conclusions Findings support concerns that maternal opiate use during pregnancy may negatively impact a child's developmental trajectory, which in turn may impose concerns to society (e.g., increased need for social, medical, and/or educational services).Many low-thermal-conductivity (κL) crystals show intriguing temperature (T) dependence of κL κL ∝ T-1 (crystal-like) at intermediate temperatures whereas weak T-dependence (glass-like) at high temperatures. It has been in debate whether thermal transport can still be described by phonons at the Ioffe-Regel limit. In this work, we propose that most phonons are still well defined for thermal transport, whereas they carry heat via dual channels normal phonons described by the Boltzmann transport equation theory, and diffuson-like phonons described by the diffusion theory. Three physics-based criteria are incorporated into first-principles calculations to judge mode-by-mode between the two phonon channels. Case studies on La2Zr2O7 and Tl3VSe4 show that normal phonons dominate low temperatures while diffuson-like phonons dominate high temperatures. Our present dual-phonon theory enlightens the physics of hierarchical phonon transport as approaching the Ioffe-Regel limit and provides a numerical method that should be practically applicable to many materials with vibrational hierarchy.Improving wood growth rate and wood quality are worthy goals in forest genetics and breeding research. The ARK1 gene is one member of the ARBORKNOX family in all plants, which play an essential role in the process of plant growth and development, but the mechanism associated with its gene network regulation is poorly investigated. In order to generate over-expression transgenic hybrid poplar, the agrobacterium-mediated transformation was used to obtain transgenic hybrid poplar '717' plants to provide insight into the function of the ARK1 gene in poplar. Sunitinib clinical trial Moreover, the morphology of transgenic plants was observed, and transcriptome analysis was performed to explore the ARK1 gene function. The results showed that there were significant differences in pitch, stem diameter, petiole length, leaf width, leaf length and seedling height between ARK1 transgenic seedlings and non-transgenic seedlings. The transgenic seedlings usually had multiple branches and slender leaves, with some leaves not being fully developed. The results of transcriptome analysis showed that the differentially expressed genes were involved in the growth of poplars, including proteins, transcription factors and protein kinases. Genes related to the positive regulation in plant hormone signal transduction pathways were up-regulated, and the genes related to lignin synthesis were down-regulated. The RT-qPCR analysis confirmed the expression levels of the genes involved in the plant hormone signal transduction pathways and phenylpropanoid pathway. In conclusion, the ARK1 gene had a positive regulatory effect on plant growth, and the gene's coding enzymes related to lignin synthesis were down-regulated.The gut microbiota is involved in a number of different metabolic processes of the host organism, including the metabolism of xenobiotics. In our study, we focused on liver cytochromes P450 (CYPs), which can metabolize a wide range of exo- and endogenous molecules. We studied changes in mRNA expression and CYP enzyme activities, as well as the mRNA expression of transcription factors that have an important role in CYP expression, all in stressed germ-free (GF) and stressed specific-pathogen-free (SPF) mice. Besides the presence of the gut microbiota, we looked at the difference between acute and chronic stress. Our results show that stress has an impact on CYP mRNA expression, but it is mainly chronic stress that has a significant effect on enzyme activities along with the gut microbiome. In acutely stressed mice, we observed significant changes at the mRNA level, however, the corresponding enzyme activities were not influenced. Our study suggests an important role of the gut microbiota along with chronic psychosocial stress in the expression and activity of CYPs, which can potentially lead to less effective drug metabolism and, as a result, a harmful impact on the organism.The heterogeneity of tinnitus is likely accounting for the lack of effective treatment approaches. Headaches have been related to tinnitus, yet little is known on how headaches impact tinnitus. We use cross-sectional data from the Swedish Tinnitus Outreach Project to i) evaluate the association between headaches and tinnitus (n = 1,984 cases and 1,661 controls) and ii) investigate the phenotypic characteristics of tinnitus subjects with tinnitus (n = 660) or without (n = 1,879) headaches. In a multivariable logistic regression model, headache was significantly associated with any tinnitus (odds ratio, OR = 2.61) and more so with tinnitus as a big problem (as measured by the tinnitus functional index, TFI ≥ 48; OR = 5.63) or severe tinnitus (using the tinnitus handicap inventory, THI ≥ 58; OR = 4.99). When focusing on subjects with tinnitus, the prevalence of headaches was 26% and reached 40% in subjects with severe tinnitus. A large number of socioeconomic, phenotypic and psychological characteristics differed between headache and non-headache subjects with any tinnitus.
