Cervical cancer (CaCx) is a global public health problem as it is the second most common cancer leading to the death of women
worldwide. Many references revealed that the low levels of antioxidants induce the generation of free radicals leading to
DNA damage and further mutations. In the present study attempt have been made to evaluate the levels of serum Lipid peroxide,
Nitric Oxide (NO.) Erythrocytic—Superoxide Dismutase (RBC-SOD), Vitamin-C, serum Copper (Cu) and serum Zinc (Zn). 120 patients were divided
in 4 groups according to the increasing CaCx stages i.e. stage I, II, III & IV respectively. All the patients were around
the age group of 25–65 years. 30 healthy women between the same age group were treated as controls. Highly significant increased
values of MDA, NO. and Cu were observed (p<0.001) whereas the activity of RBC-SOD, levels of Vitamin-C and Zn were significantly decreased in
CaCx patients as compared with healthy controls (p<0.001). Cu/Zn ratio was found to be altered in CaCx patients. From our
findings it can be concluded that the oxidative stress is induced among CaCx patients, which inturn increases the risk of
CaCx. 相似文献

The relationship between general knowledge (GK) and cognitive ability (IQ and abstract reasoning), learning approaches, and personality (‘big five’ traits and typical intellectual engagement) was investigated in a sample of 101 British undergraduates. As predicted, GK was positively correlated with cognitive ability (more so with IQ than with abstract reasoning), typical intellectual engagement, and openness to experience. A hierarchical regression showed that IQ was the strongest predictor of GK, explaining 26% of GK variance. However, openness (15%) added incremental validity to the variance explained. These results are discussed in relation to previous findings in the field of GK and the personality–intelligence interface. 相似文献

There currently exists a dearth of research on the transmission and assimilation of myths. To overcome this limitation, we developed a novel scale that measures belief in science-related myths. A total of 363 participants completed this new scale along with measures of personality (the Big Five factors), anti-scientific attitudes, and New Age orientation. Exploratory factor analysis showed that the items of the belief in myths scale could be reduced to two factors concerning human-related and non-human-related myths. Both factors were internally reliable, were moderately inter-correlated, and were not rated significantly differently by women and men (although human-related myths were rated as significantly more believable than non-human-related myths). Further analysis showed that only human myths were significantly predicted by anti-scientific attitudes and the Big Five factor of Extraversion. These results are discussed in relation to the promotion of scientific literacy. 相似文献

Very little prior research has examined public perceptions of research funding and the life chances associated with various
fields of study. In the present task, 315 members of the Austrian general public rated 34 higher-education courses in terms
of funding cuts or increases, and the perceived life chances of graduates, respectively. The results showed a high degree
of correspondence in the ratings of both questionnaires. Overall, professional and biological stream courses were rated the
most favourably, whereas arts and humanities courses were rated the least favourably. Participants’ demographic variables
had little influence on their decisions. The implications of these findings for the way higher education is managed and organised
are discussed. 相似文献

This issue contains essays by the important Japanese sinologist and intellectual historian, Mizoguchi Yūzō (1932–2010). Born in Nagoya, he studied in the literature department in Tokyo University and then went to graduate school in Nagoya University. He was a student of Iriya Yoshitaka, the famous sinologist. Mizoguchi has taught at Saitama University, Hitotsubashi University and Tokyo University. He was also a Distinguished Professor at Tokyo University. Mizoguchi Yūzō left a number of important works throughout his life. The selection is unable to provide a complete picture of Mizoguchi’s ideas about the principle of Chinese history, but it provides an entry point for English readers to understand Mizoguchi’s work. In this introduction, we attempt to bring out certain key ideas of Mizoguchi’s writings and discuss his historical and theoretical significance. 相似文献

We present an electrokinetic framework for designing insulator constriction-based dielectrophoresis devices with enhanced ability to trap nanoscale biomolecules in physiological media of high conductivity, through coupling short-range dielectrophoresis forces with long-range electrothermal flow. While a 500-fold constriction enables field focusing sufficient to trap nanoscale biomolecules by dielectrophoresis, the extent of this high-field region is enhanced through coupling the constriction to an electrically floating sensor electrode at the constriction floor. However, the enhanced localized fields due to the constriction and enhanced current within saline media of high conductivity (1 S/m) cause a rise in temperature due to Joule heating, resulting in a hotspot region midway within the channel depth at the constriction center, with temperatures of ∼8°–10°K above the ambient. While the resulting vortices from electrothermal flow are directed away from the hotspot region to oppose dielectrophoretic trapping, they also cause a downward and inward flow towards the electrode edges at the constriction floor. This assists biomolecular trapping at the sensor electrode through enabling long-range fluid sampling as well as through localized stirring by fluid circulation in its vicinity. 相似文献
