Arabidopsis Phototropins Have fun with the Damaging Dark-Induced Leaf Senescence.
CONCLUSION Our findings indicate that genes utilizing CGN arginine codons rather than AGG or AGA are more likely to underlie single-gene disorders, particularly for dominant phenotypes, and thus constitute candidate genes for the study of human genetic disease.PURPOSE To estimate the personal utility and uptake of genomic sequencing (GS) across pediatric and adult-onset genetic conditions. METHODS Three discrete choice experiment (DCE) surveys were designed and administered to separate representative samples of the Australian public. Bayesian D-efficient explicit partial profile designs were used. Choice data were analyzed using a panel error component random parameter logit model. RESULTS Overall, 1913 participants completed the pediatric (n = 533), symptomatic adult (n = 700) and at-risk adult (n = 680) surveys. The willingness-to-pay for GS information in pediatric conditions was estimated at $5470-$15,250 (US$3830-$10,675) depending on the benefits of genomic information. Uptake ranged between 60% and 81%. For symptomatic adults, the value of GS was estimated at $1573-$8102 (US$1100-$5671) and uptake at 34-82%. For at-risk adults, GS was valued at $2036-$5004 (US$1425-$3503) and uptake was predicted at 35-61%. CONCLUSION There is substantial personal utility in GS, particularly for pediatric conditions. Personal utility increased as the perceived benefits of genomic information increased. The clinical and regulatory context, and individuals' sociodemographic and attitudinal characteristics influenced the value and uptake of GS. Society values highly the diagnostic, clinical, and nonclinical benefits of GS. The personal utility of GS should be considered in health-care decision-making.The original provocative formulation of the 'geometric module' hypothesis was based on a working-memory task in rats which suggested that spontaneous reorientation behavior is based solely on the environmental geometry and is impervious to featural cues. Here, we retested that claim by returning to a spontaneous navigation task with rats and domestic chicks, using a single prominent featural cue (a striped wall) within a rectangular arena. Experiments 1 and 2 tested the influence of geometry and features separately. In Experiment 1, we found that both rats and chicks used environmental geometry to compute locations in a plain rectangular arena. In Experiment 2, while chicks failed to spontaneously use a striped wall in a square arena, rats showed a modest influence of the featural cue as a local marker to the goal. The critical third experiment tested the striped wall inside the rectangular arena. We found that although chicks solely relied on geometry, rats navigated based on both environmental geometry and the featural cue. While our findings with rats are contrary to classic claims of an impervious geometric module, they are consistent with the hypothesis that navigation by boundaries and features may involve distinct underlying cognitive computations. We conclude by discussing the similarities and differences in feature-use across tasks and species.The frequency and significance of sterility is increasing due to different socio-demographic factors in the industrialized countries. At the same time, the patients' demand for more natural and less invasive fertility treatments is increasing. The most common method used in subfertility is intrauterine insemination (IUI). Retrospectively, the data from the patients were analyzed, in which at least one insemination and a maximum of eight inseminations were performed in the last five years (observation period 01.01.2014-31.12.2018) at the Women's University Hospital Homburg. The primary endpoint was the onset of a clinical pregnancy. Clinical pregnancy was correlated with the partner's total sperm count (sperm density in millions), sperm concentration and motility during insemination. These three parameters were evaluated according the World Health Organization (WHO) 2010 guidelines. The results of the spermiograms were correlated with clinical pregnancy outcome. The data were examined for 138 women with sterility, in which a total of 345 inseminations were performed (median 2.5 per woman, range 8 inseminations). There was no correlation found between spermiogram parameters and pregnancy probability in any of the inseminations. BMS-354825 After 5 inseminations no further pregnancy occurred. The present study showed no correlation between the conception probability of intrauterine insemination (IUI) and the total sperm count/concentration/motility. After the sixth IUI, we no longer found conceptions in our patient collective. Therefore, data from this study indicate that intrauterine inseminations can be performed at all severity levels of oligoasthenozoospermia. However, the treatment should be limited to five attempts.An amendment to this paper has been published and can be accessed via a link at the top of the paper.Upon sensing starvation stress, Caenorhabditis elegans larvae (L2d) elicit two seemingly opposing behaviors to escape from the stressful condition food-seeking roaming mediated by the opioid peptide NLP-24 and dauer formation mediated by pheromones. Because opioid and pheromone signals both originate in ASI chemosensory neurons, we hypothesized that they might act sequentially or competitively to avoid starvation stress. Our data shows that NPR-17 opioid receptor signaling suppressed pheromone biosynthesis and the overexpression of opioid genes disturbed dauer formation. Likewise, DAF-37 pheromone receptor signaling negatively modulated nlp-24 expression in the ASI neurons. Under short-term starvation (STS, 3 h), both pheromone and opioid signaling were downregulated in gpa-3 mutants. Surprisingly, the gpa-3;nlp-24 double mutants exhibited much higher dauer formation than seen in either of the single mutants. Under long-term starvation (LTS, >24 h), the stress-activated SKN-1a downregulated opioid signaling and then enhanced dauer formation. Both insulin and serotonin stimulated opioid signaling, whereas NHR-69 suppressed opioid signaling. Thus, GPA-3 and SKN-1a are proposed to regulate cross-antagonistic interaction between opioids and pheromones in a cell-specific manner. These regulatory functions are suggested to be exerted via the selective interaction of GPA-3 with NPR-17 and site-specific SKN-1 binding to the promoter of nlp-24 to facilitate stress avoidance.
