The Dof transcription factor is a plant-specific transcriptional regulator that plays important roles in plant development and acts as a mediator in plant external stress responses. Avasimibe P450 (e.g. CYP17) inhibitor However, Dofs have previously been identified in several plants but not in alfalfa (Medicago sativa L.), one of the most widely cultivated forage legumes. In the present study, a total of 40 MsDof genes were identified, and the phylogenetic reconstruction, classification, conserved motifs, and expression patterns under abscisic acid (ABA), cold, heat, drought and salt stresses of these Dof genes were comprehensively analyzed. The Dof genes family in alfalfa could be classified into eight classes. Gene ontology (GO) and tissue-specific analysis indicated that most MsDof genes may be involved in biological functions during plant growth. Moreover, the expression profiles and quantitative real-time PCR analysis indicated that eight candidate abiotic tolerance genes were induced in response to four abiotic stresses. This study identified the possibility of abiotic tolerance candidate genes playing various roles in stress resistance at the whole genome level, which would provide new information on the Dof family in alfalfa.
This study evaluated the effects of cerebellar tDCS on motor learning for swallowing.

In a double-blind RCT, 39 healthy adults received either sham, anodal tDCS, or cathodal tDCS in two sessions on two consecutive days. Following 20 min cerebellar tDCS (2 mA) or sham, they underwent swallowing skill training that targeted control of timing and magnitude of submental muscle activation during swallowing. Linear mixed models were used to identify the effects of stimulation on timing and magnitude accuracy as measured by the change in task performance for each training session, and for skill retention on days 3 and 10 post-intervention.

Only the sham group had a reduced temporal error from baseline to all following timepoints. When compared to error changes in the sham group, changes from baseline in temporal errors were higher at all timepoints post-intervention for the anodal group, and higher at both retention assessments for the cathodal group. Amplitude errors were smaller for all conditions at all tim in swallowing. For the tDCS parameters used in this study, there is no support for use of tDCS to facilitate swallowing rehabilitation. Trial Registry Number (https//www.anzctr.org.au/) ACTRN12615000451505. IMPLICATIONS FOR REHABILITATION Cerebellar tDCS, in combination with motor skill training, has been demonstrated to increase motor skill learning in healthy individuals and neurologically impaired patients. In this study, cerebellar tDCS applied prior to swallowing skill training adversely affected timing measures of submental muscle activation during swallowing. In contrast to published outcomes in the corticospinal literature, both anodal and cathodal tDCS resulted in a relative inhibitory effect on motor skill learning in swallowing when compared to the sham condition. Swallowing skill training without tDCS produced increased accuracy in outcomes.A combination of positively and negatively worded items (termed a mixed-format design) has been widely adopted in personality and attitude assessments. While advocates claim that the inclusion of positively and negatively worded items will encourage respondents to process the items more carefully and avoid response preference, others have reported that negatively worded (NW) items may induce a nuisance factor and contaminate scale scores. The present study examined the extent of the impact of the NW-item feature and further investigated whether a mixed-format design could effectively control acquiescence and the preference for extreme response options using two datasets (Attitude toward Peace Walls, and International Personality Item Pool). A proposed multidimensional item response model was implemented to simultaneously estimate the impact of item feature and response preference. The results suggested that NW items induced an impact on item responses and that affirmative preference was negligible, regardless of the proportion of NW items in a scale. However, participants' extremity preference was large in both balanced and imbalanced mixed-format designs. It concludes that the impact of the NW-item feature is not negligible in a mixed-format scale, which exhibits good control of acquiescence but not extremity preference.
Multiple prognostic models are available to predict mortality in alcoholic hepatitis (AH) which are of modest benefit, but the best model remains unexplored.

This is a retrospective analysis (2012-2015) of AH patients. Conventional prognostic scoring systems viz. Maddrey's Discriminant Function (mDF), Age Bilirubin International Normalized Ratio and Creatinine (ABIC), Glasgow Alcoholic Hepatitis Score (GAHS), and the Model for End-stage Liver Disease score (MELD), were compared with Model for AH to Grade the Severity in an Asian patient cohort (MAGIC) score, using area under the ROC curves for ascertaining 30/90-day mortality.

Eighty-eight patients (100% male); mean (SD) age of 45.6 (7.6) years with a follow-up of 80.7 (45.1) days were included. The 30 and 90-day mortality were 21 (23.9%) and 42 (47.7%), respectively; the commonest cause being sepsis in 22 (48.9%) patients. Survival probabilities for mDF < 32 and mDF > 32 were 100% and 42.25% ± 4.46%, respectively (
= .001). The mean (SD) scores of mDF, MELD and GAHS were significantly higher in deceased patients 70.8 (26.5), 23.4 (5.2), 8.1 (1.01), respectively, as compared to those who survived 40.8 (23.1), 18.9 (5.1), 7.3 (0.9), respectively;
 = .001. ABIC and MAGIC scores were higher among the deceased, but were not significant. mDF had the best predictive AUROC value 0.872, followed by MELD 0.772, and MAGIC 0.626, respectively. mDF was significantly superior in comparison to MAGIC score (
 < .001).

This study showed that mDF had a better predictive performance than other scoring systems in patients with AH.
