Objective: Hypoactivity in the reward system among patients with attention deficit hyperactivity disorder (ADHD) is a well-known phenomenon. Whether the activity in the reward pathway is related to harm avoidance, such as in sensitivity to punishment, is unclear. Evidence regarding the potential difference between ADHD patients and controls in terms of this association is scarce. Methods: Event-related functional magnetic resonance imaging was conducted on subjects performing the Iowa gambling test. Fourteen adults with ADHD and 14 controls were enrolled in the study. Results: Harm avoidance was found to be positively correlated with the activities of the bilateral orbitofrontal cortex and right insula in individuals with ADHD. A group difference was also confirmed. Conclusion: Understanding the roles of harm avoidance and brain activation during risk tasks is important.

In this study, conductive polymer composites and conductive functional fabrics are combined to serve aselectromagnetic shielding planks. Polypropylene (PP), carbon black (CB), and short carbon fibers (SCF) are blended atdifferent ratios to form conductive polymer composites (i.e. PCS series). The mechanical property, electrical property,morphology, and electromagnetic interference shielding effectiveness (EMI SE) of the PCS series are evaluated. The testresults show that with 20 wt% of conductive fillers (i.e. CB and SCF), PCS20 exhibits the optimal tensile strength, flexuralstrength, and electrical property that is 7 order of magnitude higher than that of pure PP plates. Moreover, the EMI SE of thisgroup also reaches -30 dB, which meets level one of civil EMI SE standard. Therefore, PCS20 is used to combine with fourconductive sandwiches. The resulting multilayered functional PCS-sandwich planks are tested in terms of mechanicalproperty, morphology, and EMI SE. The test results show that the planks composed of a pure conductive woven sandwichhave the maximum tensile property and significantly improved impact resistance. All of the multilayered functional plankshave EMI SE that is higher than -50 dB and are qualified for the protection level of standard EMI SE electronic devices.

Numerous studies have indicated that organic fertilizers (OFer) might contain heavy metals (HMs) that present health risks to organic farmers (OFar). This study compared the concentrations of six HMs (Zn, Ni, Cd, Cu, Pb, Cr) in the blood of two distinct groups of farmers: 30 OFar from a designated organic area in eastern Taiwan, and 74 conventional farmers (CFar) from neighboring non-organic designated regions. The findings revealed that the OFar exhibited higher levels of Zn (1202.70 ± 188.74 μg/L), Cr (0.20 ± 0.09 μg/L), and Ni (2.14 ± 1.48 μg/L) in their blood compared to the CFar (988.40 ± 163.16 μg/L, 0.18 ± 0.15 μg/L, and 0.77 ± 1.23 μg/L), respectively. The disparities in Zn, Cr, and Ni levels were measured at 214.3 μg/L, 0.02 μg/L, and 1.37 μg/L, respectively. Furthermore, among the OFar, those who utilized green manures (GM) displayed significantly elevated blood levels of Zn (1279.93 ± 156.30 μg/L), Cr (0.24 ± 0.11 μg/L), and Ni (1.94 ± 1.38 μg/L) compared to individuals who exclusively employed chemical fertilizers (CFer) (975.42 ± 165.35 μg/L, 0.19 ± 0.16 μg/L, and 0.74 ± 1.20 μg/L), respectively. The differences in Zn, Cr, and Ni levels were measured at 304.51 μg/L, 0.05 μg/L, and 1.20 μg/L, respectively. As a result, OFar should be careful in choosing OFer and avoid those that may have heavy metal contamination.

This study used the structural equation modeling (SEM) of SPSS and AMOS to verify the hypotheses on the correlation between various dimensions, which were all supported. The correlations were significantly positive. The results showed that the effect of consumer health concept on algae product knowledge is significantly positive, where path coefficient is 0.9, indicating that consumers with health concept are more willing to accept new algae product knowledge, thereby affecting their purchase intention on algae product.

Post-earthquake fire is a common disaster which causes serious safety issues to infrastructures. This study aims to investigate the residual loading capacities of circular concrete-filled steel tube (CFST) columns under post-earthquake fire experimentally and numerically. The experimental programme contains two loading steps - pre-damage cyclic loading at room temperature and transient state tests with constant compression loads. Three finite element models are developed and validated against the test results. Upon validation, a total of 48 numerical results were generated in the parametric study to investigate the effects of thickness and strengths of steel tube, axial compression ratio and damage degree on the fire resistance of circular CFST columns. Based on the analysis on experimental and numerical results, the loading mechanism of circular CFST columns is discussed. A design method is proposed for the prediction of fire resistance time under different seismic pre-damage and compression loads. The predictions by the new method is compared with the newly generated experimental and numerical results and is found to be accurate and consistent with the mean value close to the unity and a coefficient of variation around 1%.

Purpose: To investigate the diet of patients with cervical cancer and precancerosis in the Wufeng area, a high-incidence region in China. Methods: In the case group, 104 patients diagnosed with cervical cancer or cervical intraepithelial neoplasias (CINII/III) were recruited from the Wufeng area. Nine hundred thirty-six healthy women were selected from the same area as the matched controls. A questionnaire, which included questions about general lifestyle conditions, smoking and alcohol status, source of drinking water, green tea intake, and diet in the past year, was presented to all participants. Results: Green tea intake (P=0.022, OR=0.551, 95% CI=0.330-0.919) and vegetable intake (P=0.035, OR=0.896, 95% CI=0.809-0.993) were identified as protective factors against cervical cancer or CINII/III. There was no indication of any associations of other lifestyle factors (smoking status, alcohol status, source of drinking water) or diet (intake of fruit, meat/egg/milk, soybean food, onion/garlic, staple food and pickled food) with cervical cancer. Conclusions: The results suggest that eating more fresh vegetables and drinking more green tea may help to reduce the risk of cervical cancer or CINII/III in people of the Wufeng area.

Objective: Loneliness is a specific risk factor for depressive symptoms and suicidal behavior. The present study examined whether the serum oxytocin level would interact with social support and buffers loneliness and hypothalamic-pituitary- adrenal (HPA)-axis activity in drug-naïve patients with major depressive disorder (MDD). Methods: Twenty-six patients with MDD (male:female = 3:23; mean age, 45.54 ± 12.97 years) were recruited. The 17-item Hamilton Depression Rating Scale, UCLA Loneliness Scale and self-reported Measurement of Support Function Questionnaire were administered. Serum oxytocin and cortisol levels were assessed using a commercial immunoassay kits. Results: In MDD patients, a negative association was found between degrees of social support and loneliness ( = −0.39, p = 0.04). The interaction between social support and serum oxytocin level was negatively associated with loneliness ( = −0.50, p = 0.017) and serum cortisol level ( = −0.55, p = 0.020) after adjusting for age. Follow-up analyses showed that the association between higher social support and lower loneliness was observed only in the higher-oxytocin group (r = −0.75, p = 0.003) but not in the lower group (r = −0.19, p = 0.53). The significance remained after further adjusting for sex and depression severity. Conclusion: Low oxytocin level is a vulnerability factor for the buffering effect of social support for loneliness and aberrant HPA-axis activity in MDD patients.

Fertilizer and plant-growth-promoting microorganisms (PGPMs) both benefit crop growth; however, little isknown about the interaction effects when they are combined. This study assessed the effect of PGPMs andfertilizer on plant growth, foliar chemistry, and subsequent insect feeding. Cabbage and tomato plants wereinoculated with PGPMs (fungi and bacteria) and various levels of fertilization. Plant growth parameters (freshweight, dry weight, and leaf area) and foliar chemistry (water content, protein content, and polyphenol oxidaseactivity) were then analyzed. In addition, foliage was also fed to the third instar larvae of Spodoptera litura toevaluate foliage quality. The results indicated that plant performance differed significantly among treatments,and the combined fungi Meyerozyma guilliermondii and fertilizer treatment promoted the greatest plant growth. In summary, PGPMs and fertilization can have their owneffect; their interaction effect, however, need to be clarified.
