Working memory tasks designed for children usually present trials in order of ascending difficulty, with testing discontinued when the child fails a particular level. Unfortunately, this procedure comes with a number of issues, such as decreased engagement from high-ability children, vulnerability of the scores to temporary mind-wandering, and large between-subjects variations in number of trials, testing time, and proactive interference. To circumvent these problems, the goal of the present study was to demonstrate the feasibility of assessing working memory using an adaptive testing procedure...

Despite recent comprehensive genetic analyses, molecular evidence for a pathophysiological continuum linking benign adrenocortical adenoma (ACA) and highly aggressive adrenocortical carcinoma (ACC) is still elusive. Using human tumor samples and the established ACC cell line SW-13, this study investigated potential regulatory roles for FOXO transcription factors, in modulating adrenocortical tumorigenesis. Adrenocortical tumor specimens (20 ACAs, 10 ACCs, and 9 normal adrenal tissue samples) obtained from 30 patients were analyzed for ubiquitously expressed FOXO transcription factors, FOXO1 and FOXO3 using qRT-PCR and immunohistochemistry...

Inappropriate use of antibiotics in clinical settings is thought to have led to the global emergence and spread of multidrug-resistant pathogens. The goal of this study was to investigate the prevalence of genes encoding aminoglycoside resistance and plasmid-mediated quinolone resistance among clinical isolates of Klebsiella pneumoniae. All K. pneumoniae isolates were phenotypically identified using API 20E and then confirmed genotypically through amplification of the specific K. pneumoniae phoE gene. All isolates were genotyped by the enterobacterial repetitive intergenic consensus polymerase chain reaction technique (ERIC-PCR)...

Cortico-striato-thalamo-cortical (CSTC) circuit has been implicated in OCD pathophysiology by converging neuroimaging findings. The anterior cingulate cortex (ACC), as an important part within CSTC circuit, plays a critical role in OCD etiology. The ACC can be divided into dorsal and rostral parts anatomically, which are involved in cognitive process and emotional function, respectively. However, the diverse function of intrinsic signals from dorsal and rostral ACC regions remains unclear in OCD study. In this work, we applied resting-state functional magnetic resonance imaging (rs-fMRI) technology to investigate and differentiate the functional connectivity (FC) characteristics between dACC and rACC in unmedicated OCD patients...

Our previous work showed that purple sweet potato color (PSPC), a class of naturally occurring anthocyanins, effectively improved hepatic glucose metabolic dysfunction in high-fat diet (HFD)-treated mice. This study investigated the effects of PSPC on HFD-induced hepatic steatosis and the signalling events associated with these effects. Mice were divided into four groups: Control group, HFD group, HFD+PSPC group and PSPC group. PSPC was administered daily for 20 weeks at oral doses of 700 mg/kg/day. Our results showed that PSPC significantly improved obesity and related metabolic parameters, as well as liver injury in HFD-treated mice...

In the last two decades the anterior cingulate cortex (ACC) has become one of the most investigated areas of the brain. Extensive neuroimaging evidence suggests countless functions for this region, ranging from conflict and error coding, to social cognition, pain and effortful control. In response to this burgeoning amount of data, a proliferation of computational models has tried to characterize the neurocognitive architecture of ACC. Early seminal models provided a computational explanation for a relatively circumscribed set of empirical findings, mainly accounting for EEG and fMRI evidence...

The 2013 American College of Cardiology/American Heart Association (ACC/AHA) guideline on cholesterol treatment to prevent atherosclerotic cardiovascular disease (ASCVD) has been criticized for lowering the risk thresholds for primary prevention with statin therapy. Although the ≥ 7.5% (class I) and ≥ 5% (class IIa) 10-year ASCVD risk thresholds were identified as new indications for treatment by extrapolating results obtained in randomized controlled trials (RCT) of statin therapy, results from population-based European cohorts indicate that >30% of individuals eligible for statin therapy by class I recommendations do not have RCT data supporting statin efficacy...

The perception of visceral pain is a complex process involving the spinal cord and higher order brain structures. Increasing evidence implicates the gut microbiota as a key regulator of brain and behavior, yet it remains to be determined if gut bacteria play a role in visceral sensitivity. We used germ-free mice (GF) to assess visceral sensitivity, spinal cord gene expression and pain-related brain structures. GF mice displayed visceral hypersensitivity accompanied by increases in Toll-like receptor and cytokine gene expression in the spinal cord, which were normalized by postnatal colonization with microbiota from conventionally colonized (CC)...

This study examined situational, psychological, and neurobiological factors associated with deceptive behavior in 8-year-old children. By assessing deception in low- and high-risk conditions, we differentiated between children displaying some dishonesty and children who deceived repeatedly, and we assessed the correlates of deception in 163 children. A large majority of the children were deceptive in the low-risk condition (n=121, 74.2%), but most children refrained from deception when at risk for getting caught (69 of 121)...
