Quantifying prefrontal cortex activity during resting states provides a baseline for interpreting task-induced brain activity. Researchers commonly use resting conditions where participants are prompted to stare at a screen (eyes open) or close their eyes (eyes closed). Are these two conditions equivalent representations of a baseline resting state? Further, does prefrontal cortex activity during these conditions change as a function of development? The aim of this study was to examine differences in prefrontal cortex activity between eyes open and eyes closed conditions during resting states in children and adults to provide a rationale of proper selection of baseline condition in future research. Thirty-six participants in 3 age groups were recruited in this study including twenty-four adults, five 12 - 15 years old children, and seven 8 - 11 years old children. Relative changes in concentrations of oxygenated hemoglobin (Δoxy-Hb) and deoxygenated hemoglobin (Δdeoxy-Hb) were obtained by using functional Near-Infrared Spectroscopy (fNIRS) in eyes closed (EC) and eyes open (EO) conditions, 3 minutes each. Contrasts were tested to compare the differences of Δoxy-Hb and Δdeoxy-Hb between eyes open and eyes closed conditions. The EC condition had significantly higher Δoxy-Hb than EO when all groups were combined (t (17.268) = 3.021, p = .008, Cohen’s d = –0.72). When comparing Δoxy-Hb between eyes conditions within each group, the younger group had significantly higher Δoxy-Hb in EC than EO (t (9.459) = 2.734, p = 0.022, Cohen’s d = –1.46). Based on these results, the EO condition may be a better baseline condition, particularly in studies with younger children, since it has less activity in the PFC that could interfere with interpretations of task-induced activity.展开更多

From the comparison with published theoretical results, computer simulation and experimental data, its validity and convenience in system design and evaluation are shown. Using this simple and general formula, one can easily obtain the dispersion limit of various fiber types under different working conditions in IM/DD systems.展开更多

But one day a sudden gust of fierce wind blew in from the western sky and continued for days and days. On the ninth day, a cloud of smoke welled up from the west and covered the sun. The frightened people were left in terrible darkness. Yong Jian, a broad-shouldered youth who lived in Dongfeng Village at the foot of Fenghuang Mountain, made up his mind to remove the evil smoke and bring the sunshine back to the people. One day, Yong Jian met with an old man with a long beard. He told Yong Jian that there lived two nine-antler dragons in the western Shuanglong Mountain who had been preparing themselves for this moment for 9,990 years. The old man said that after展开更多

Trauma-caused vision-threatening conditions such as open global injury, traumatic optic neuropathy and proliferative vitreoretinopathy are particularly discussed. Also the most updated clinic research in China as Eye Injury Vitrectomy Study is discussed. At the end, the current achievements and research in traumatic eye injury in the world are summerized.展开更多

It measures about 8%-14% of total childhood injuries. This study aims to determine the epidemiological profile of ocular trauma in the pediatric age group attending a tertiary hospital in northern India. Methods: A retrospective study was conducted in our hospital between June 2014 to July 2015 and all the children aged 0-16 years presenting with ocular trauma in eye outpatient department and emergency were enrolled in the study. Various epidemiological parameters like age, sex distribution, duration of presentation, mode of injury, type of injury and final visual outcome were analyzed. Results: Of total 357 patients, 271 (76%) were below the age of 12 years: 41.1% of children with ocular trauma belonged to age group 2-6 years. The male to female ratio was 2.9:1. Out of total patients, 242 (67.8%) presented with closed globe injury. Among the closed globe injury, the history of fall was present in about 35% of children, followed by trauma while playing with bat/ball (15.7%) and finger nail trauma (13.2%). Among open globe injury, trauma with needle, knife, glass and pen were common causes. Home was the most common place of injury (47.8%), followed by streets (17.9%) and playground (14.9%). Conclusion: Children are vulnerable to ocular trauma and need more supervision. Sharp objects like needles, knives, household chemicals like acids should be out of reach of children.展开更多
