<p>Functional near-infrared spectroscopy (fNIRS) was used to test whether monitoring inhibition-related brain regions is a feasible method for detecting both infrequent liars and frequent liars. Thirty-two participants were divided into two groups: the deceptive group (liars) and the non-deceptive group (ND group, innocents). All the participants were required to undergo a simulated interrogation by a computer. The participants from the deceptive group were instructed to tell a mix of lies and truths and those of the ND group were instructed always to tell the truth. Based on the number of deceptions, the participants of the deceptive group were further divided into a infrequently deceptive group (IFD group, infrequent liars) and a frequently deceptive group (FD group, frequent liars). The infrequent liars exhibited greater neural activities than the frequent liars and the innocents in the left middle frontal gyrus (MFG) when performing the deception detection tasks. While performing deception detection tasks, infrequent liars showed significantly greater neural activation in the left MFG than the baseline, but frequent liars and innocents did not exhibit this pattern of neural activation in any area of inhibition-related brain regions. The results of individual analysis showed an acceptable accuracy of detecting infrequent liars, but an unacceptable accuracy of detecting frequent liars. These results suggest that using fNIRS monitoring of inhibition-related brain regions is feasible for detecting infrequent liars, for whom deception may be more effortful and therefore more physiologically marked, but not frequent liars.</p

Essential Metals Zinc, Selenium, and Strontium Protect against Chromosome Damage Caused by Polycyclic Aromatic Hydrocarbons Exposure
Essential metals play important roles
in maintaining cellular homeostasis,
but the effects of their interaction with the environmental pollutants
are still not very well-known in human subjects. The aim of this study
was to evaluate the roles of essential metals and their interactions
with polycyclic aromatic hydrocarbons (PAHs) on chromosome damage,
an early carcinogenic event. A total of 1245 male workers were included
in this study and the levels of 11 urinary essential metals, 12 urinary
PAH metabolites, plasma concentrations of benzoÂ[a]Âpyrene-r-7,t-8,t-9,c-10-tetrahydotetrol-albumin
(BPDE-Alb) adducts, and lymphocyte micronucleus (MN) frequencies were
monitored. We found that zinc (Zn), selenium (Se), and strontium (Sr)
have significant inverse dose–response relationships with MN
frequencies (all <i>P</i> < 0.05). Furthermore, the protective
roles of Zn, Se, and Sr were mainly shown among subjects with high
levels of BPDE-Alb adducts. Significant effect modification of BPDE-Alb
adducts on the associations of Zn, Se, and Sr with MN frequencies
was observed (all <i>P</i><sub>interaction</sub> < 0.05).
Our study showed evidence that Zn, Se, and Sr play protective roles
in reducing chromosome damage, and these effects can be modified by
PAH exposure levels. These findings add potential evidence for the
preventive effects of Zn, Se, and Sr against carcinogenesis in human
subjects

Association of Urinary Metal Profiles with Altered Glucose Levels and Diabetes Risk: A Population-Based Study in China
<div><p>Background</p><p>Elevated heavy metals and fasting plasma glucose (FPG) levels were both associated with increased risk of cardiovascular diseases. However, studies on the associations of heavy metals and essential elements with altered FPG and diabetes risk were limited or conflicting. The objective of this study was to evaluate the potential associations of heavy metals and essential trace elements with FPG and diabetes risk among general Chinese population.</p><p>Methods</p><p>We conducted a cross-sectional study to investigate the associations of urinary concentrations of 23 metals with FPG, impaired fasting glucose (IFG) and diabetes among 2242 community-based Chinese adults in Wuhan. We used the false discovery rate (FDR) method to correct for multiple hypothesis tests.</p><p>Results</p><p>After adjusting for potential confounders, urinary aluminum, titanium, cobalt, nickel, copper, zinc, selenium, rubidium, strontium, molybdenum, cadmium, antimony, barium, tungsten and lead were associated with altered FPG, IFG or diabetes risk (all P< 0.05); arsenic was only dose-dependently related to diabetes (P< 0.05). After additional adjustment for multiple testing, titanium, copper, zinc, selenium, rubidium, tungsten and lead were still significantly associated with one or more outcomes (all FDR-adjusted P< 0.05).</p><p>Conclusions</p><p>Our results suggest that multiple metals in urine are associated with FPG, IFG or diabetes risk. Because the cross-sectional design precludes inferences about causality, further prospective studies are warranted to validate our findings.</p></div
