Discovering Genotype-by-Environment Connections of Substance Structure regarding Raspberry by Using a Metabolomics Strategy.
To evaluate the feasibility of implementing a clinical trial protocol of the herbal seeds Ziziphus spinosa (ZS) for people with insomnia.

A randomized, double-blind, placebo controlled, cross-over feasibility trial in Melbourne, Australia.

After two-week run-in participants were randomized to either ZS (encapsulated granules; 2 g daily) or placebo for four weeks. After four-weeks wash-out, participants swapped to the other treatment for four weeks.

Sleep quality assessed by the Insomnia Severity Index and Pittsburgh Sleep Quality Index (PSQI). Quality of life, mood, functional impairment and sleep parameters were also assessed.

Twelve participants were randomized and completed both periods of cross-over (six in each sequence). Feasibility endpoints were acceptable. Improvements for sleep quality measured on the PSQI were statistically significant during the ZS treatment periods compared to placebo (t = -2.276, df = 10, 95 % CI -3.3 to -0.04, p = 0.046). selleck chemical There was no evidence of any significant carryover effects. However, there were period effects. Other outcomes showed no statistically significant difference between the treatments. Subjective sleep parameters measured on sleep diaries showed improvements after ZS in terms of total sleep time, sleep efficiency and sleep onset latency, but not after placebo. ZS was well tolerated with only minor adverse events.

ZS is an acceptable and well-tolerated herbal candidate for the treatment of insomnia. The feasibility objectives of this study were achieved and ZS improved both subjective sleep quality and quantity compared to placebo. ZS should be explored in future clinical trials.

This study deals with the analysis of uncertainties in the data on material properties and model parameters, and their influence on the results delivered by advanced computational models of lyophilisation. As a means of uncertainty analysis, the Stochastic Collocation Method is applied, allowing the use of existing reliable deterministic models as black boxes in the stochastic computations. As a deterministic model, the lyophilisation model is used, based on the axisymmetric approximation of a vial, and the Boundary Element Method as a solver. Five parameters, covering material properties, process conditions and model constants, are selected for the sensitivity analysis simulation of the lyophilisation of an aqueous mannitol solution. The results show that during the initial stage of the primary drying heat transfer from the shelf is crucial, and that the uncertainties in the contact surface area and material properties of the vial play a more important role than the thermal properties of the drying material. When the temperature of the material reaches its distinct primary drying stage level the mass transfer through the porous cake becomes the most important, with great sensitivity to the Knudsen diffusivity in the porous cake. We observed uncertainties in the results for the primary drying time in the order of ±6%, and uncertainties in the results for temperatures of ±0.6°C in the frozen material and ±3°C in the porous cake. The uncertainty analysis proved to be a great help in determining the critical parameters in the heat and mass transfer during the important primary drying step, which led to a better definition of the numerical model for use in the context of design space determination.Gibbons et al.1 demonstrated the utility of computerized adaptive tests (CATs) based on multidimensional item response theory for the assessment of depression, anxiety, mania/hypomania, attention-deficit/hyperactivity disorder, conduct disorder, oppositional defiant disorder, and suicidality in children and adolescents. The Kiddie-Computerized Adaptive Test (K-CAT) demonstrated good convergent validity, test-retest reliability, and diagnostic concordance with diagnoses derived using the paper-and-pencil Schedule for Affective Disorders and Schizophrenia for School-Age Children (K-SADS) child psychiatric interview.
Infant amygdala connectivity correlates with maternal reports of infant temperament characterized by novelty-evoked distress and avoidance. However, no studies have examined how human infant amygdala connectivity relates to direct observations of novelty-evoked distress. This study examined the link between amygdala connectivity and infant novelty-evoked distress using direct observation of temperament.

Novelty-evoked distress was assessed at 4 months of age (N= 90) using a standardized reactivity assessment and parent report. Within 3 weeks of assessment, resting-state functional magnetic resonance imaging was collected in a subset of infants (n= 34). Using a whole-brain voxelwise approach, amygdala connectivity associated with positive and negative affect during the reactivity assessment was examined. Regions where the association of amygdala connectivity with negative affect was higher than with positive affect were then examined. Associations between amygdala connectivity and parent report of temperam control mechanism to temperamental risk for anxiety.We thank Kaufman et al.1 for their comprehensive review of the many commendable features of the Kiddie-Computerized Adaptive Test (K-CAT). We do wish to clarify what may be a misunderstanding of the intent of the K-CAT and our view of its role in treatment planning.In their article in the Journal, Sprengers et al.1 conclude that bumetanide does not attenuate autism spectrum disorder (ASD) despite a nominally significant treatment effect in repetitive behaviors, which is a core symptom of ASD but was defined as a secondary measure in this trial. Four earlier studies performed by 3 independent institutes, including 2 studies2,3 not mentioned by Sprengers et al., testing a total of 169 children (versus 122 placebo) showed a significant amelioration of ASD symptoms. Bumetanide also significantly attenuated behavioral features of patients with tuberous sclerosis according to another study by Sprengers' same group.4.
