Input: Consider Input: Context: Event-related potentials (ERPs) are sensitive measures of both perceptual and cognitive processes. The aim of the present study was to identify brain regions involved in the processes of cognitive dysfunction in narcolepsy by means of ERP tomography.', 'In 17 drug-free patients with narcolepsy and 17 controls, ERPs were recorded (auditory odd-ball paradigm). Latencies, amplitudes and LORETA sources were determined for standard (N1 and P2) and target (N2 and P300) ERP components. Psychometry included measures of mental performance, affect and critical flicker fusion frequency (CFF).', 'In the ERPs patients demonstrated delayed cognitive N2 and P300 components and reduced amplitudes in midline regions, while N1 and P2 components did not differ from controls. LORETA suggested reduced P300 sources bilaterally in the precuneus, the anterior and posterior cingulate gyri, the ventrolateral prefrontal cortex and the parahippocampal gyrus. In psychometry, patients demonstrated deteriorated mood, increased trait anxiety, decreased CFF and a trend toward reduced general verbal memory and psychomotor activity.
Answer: Narcoleptic patients showed prolonged information processing, as indexed by N2 and P300 latencies and decreased energetic resources for cognitive processing.

Output: Does event-related-potential low-resolution brain electromagnetic tomography ( ERP-LORETA ) suggest decreased energetic resources for cognitive processing in narcolepsy?


Input: Consider Input: Context: The interaction between Siglec-10 and its ligand, CD24, selectively represses tissue damage-caused immune responses. However, the nature of Siglec-10 and CD24 in human hepatocellular carcinoma (HCC) is still poorly defined. Hereon, the expression, function, and regulation of CD24 and Siglec-10 in HCC were investigated in the present study.', 'Flow cytometry was performed to examine the expression of Siglec-10 in HCC tissues and adjacent non-tumor tissues of HCC patients. To further determine whether Siglec-10 expression is associated with the clinical characteristics and survival, conventional immunohistochemistry was performed in 96 HCC patients. Additionally, the role of Siglec-10 in the regulation of natural killer (NK) cell dysfunction was evaluated. Finally, CD24 expression in HCC was also assessed.', 'Siglec-10 was expressed most on NK cells in HCC (40.7 ± 4.5%). Compared with surrounding non-tumor tissues, tumor tissues had higher Siglec-10 expression (31.0 ± 1.7% versus 40.7 ± 4.5%, n = 10, P < 0.05), and the expression was negatively associated with patient survival. Siglec-10(+)CD56(+) NK cells exhibited reduced effector function, as shown by decreased granules and cytokine expressions compared with Siglec-10(-)CD56(+) NK cells. Moreover, the number of CD24(+)CD45(-) cells in HCC tissues was higher than that in adjacent non-tumor tissues (9.4 ± 0.9% versus 3.1 ± 0.9%, n = 15, P < 0.05).
Answer: These findings suggest that Siglec-10 is associated with decreased survival and impaired NK cell function in human HCC. This process may function via the CD24-Siglec-10 interaction, which may represent a therapeutic target in HCC patients.

Output: Is siglec-10 associated with survival and natural killer cell dysfunction in hepatocellular carcinoma?


Input: Consider Input: Context: Gene flow from crops to their wild relatives has the potential to alter population growth rates and demography of hybrid populations, especially when a new crop has been genetically modified (GM). This study introduces a comprehensive approach to assess this potential for altered population fitness, and uses a combination of demographic data in two habitat types and mathematical (matrix) models that include crop rotations and outcrossing between parental species.', 'Full life-cycle demographic rates, including seed bank survival, of non-GM Brassica rapa\u2009×\u2009B. napus F1 hybrids and their parent species were estimated from experiments in both agricultural and semi-natural habitats. Altered fitness potential was modelled using periodic matrices including crop rotations and outcrossing between parent species.', 'The demographic vital rates (i.e. for major stage transitions) of the hybrid population were intermediate between or lower than both parental species. The population growth rate (λ) of hybrids indicated decreases in both habitat types, and in a semi-natural habitat hybrids became extinct at two sites. Elasticity analyses indicated that seed bank survival was the greatest contributor to λ. In agricultural habitats, hybrid populations were projected to decline, but with persistence times up to 20 years. The seed bank survival rate was the main driver determining persistence. It was found that λ of the hybrids was largely determined by parental seed bank survival and subsequent replenishment of the hybrid population through outcrossing of B. rapa with B. napus.
Answer: Hybrid persistence was found to be highly dependent on the seed bank, suggesting that targeting hybrid seed survival could be an important management option in controlling hybrid persistence. For local risk mitigation, an increased focus on the wild parent is suggested. Management actions, such as control of B. rapa, could indirectly reduce hybrid populations by blocking hybrid replenishment.


Output: Do seed bank dynamics govern persistence of Brassica hybrids in crop and natural habitats?
