Twenty-six patients' parents were available as a first-degree relatives group and 100 biologically unrelated healthy controls were collected as the control group. Based on the age of onset and seizure type, the patients were divided into six subgroups. Polymerase chain reaction and DNA direct sequencing analysis showed that the most frequent mutations c. 1249dupC (p.Gly418Argfx31 ) and c.1636A 〉 G (p.Thr546Ala) were detected in some idiopathic generalized epilepsy patients and tl^eir asymptomatic first-degree relatives (30.6% vs. 19.2% and 11.2% vs. 26.9%). A novel mutation c.1807G 〉A (p.Val603Met) was found in a patient with late-onset idiopathic generalized epilepsy. There was no significant difference in the incidence of these three mutations among the different subgroups of idiopathic generalized epilepsy and controls. Thus, further analysis of a larger population is needed to confirm the assumption that human seizure-related gene 6 is a susceptibility gene for idiopathic generalized epilepsy with various sub-syndromes.展开更多

The minimum dietary selenium requircment for the prevention of Keshan disease (KD) was found to be around 17 μg/d. On the other hand, an intake of 40 μg/d is required to maintain the plasma glutathione peroxidase (GPx) activity at plateau. Hence 40 μg/d is considered as the adequate dietary selenium requirement. Studies conducted in a chronic selenosis area indicate thai the toxic dietary selenlum inlake (adverse effect level), which would maintain the characteristic fingernail changes, was approximately 1600 μg/d. The mean value of dietary selenium intakes, which enabled the five patients to recover from fingernail lesions, was found to be 819 ±126μg/d. At a 95% confidence limit, the lower limit is around 600μg/d. Therefore, 600 and 400μg/d were suggested as the individual daily maximum safe selenium intake and the safe dietary selenium intake, respectively,The results were used in the prevention of Se-related endemic KD and Kashin-Beck disease (KBD)展开更多

Kallikrein-related peptidase 5 (KLK5) is a secreted trypsin-like protease of the KLKs. Until now, detection of KLK5 in both biological fluids and tissues has been described frequently due to the potential of being a new cancer biomarker. Our objective was to prepare KLK5 antibodies and establish an ELISA method for KLK5 to study the possible clinical application of KLK5 as a biomarker for malignancies. In this study, recombinant KLK5 protein was produced and purified using a prokaryotic expression system, and then used as immunogen to generate antibodies. High titers of specific antibodies were measured in serum of rabbits after the forth booster injection. And the titer of the antiserum reached 1:106. We have also generated monoclonal antibodies using hybridoma technology and the titer reached 1:105. The activity of KLK5 antibodies was characterized by Western blot and immunohistochemistry. To quantitatively examine KLK5 in serum samples, we established double antibody sandwich ELISA method using mouse mAb as capture and rabbit pAb as tracer antibody. We have detected KLK5 levels in ovarian cancer serum to ensure that our sandwich ELISA measurement to have high sensitivity and specificity. The ranges of linearity reached by the standard curves of the newly developed ELISA were 0.45 ng/mL to 125 ng/mL. The detection limit of the method, defined as the concentration of KLK5 can be distinguished, was 0.20 ng/mL. Median serum KLK5 levels were 3.77 ng/mL and 0.86 ng/mL in ovarian cancer patients and normal female, respectively (P ELISA assay for KLK5. Our preliminary findings prompt that KLK5 may be a new potential biomarker for the diagnosis and prognosis in patients with ovarian.展开更多

A soluble and truncated exfoliated form of the activity is present in blood and other body fluids. The activity was purified to apparent homogeneity from human urine and resolved by 2-D gel electrophoresis into a series of 24 to 32 kDa components of low isoelectric point. The purified proteins were resistant both to N-terminal sequencing and trypsin cleavage. Cleavage with pepsin revealed peptides corresponding to the TM9 family of transmembrane proteins. Peptide antisera raised to all five members of the human TM9 family sequentially blocked the arNOX activity of human saliva and sera. The soluble truncated N-terminus of the human homolog TM9SF4 was expressed in bacteria. The recombinant protein was characterized biochemically and exhibited ar-NOX activity. The findings identify five arNOX isoforms each of which correspond to one of the five known TM9 family members. The exfoliated soluble arNOX forms are derived from the 24 to 32 kDa N-termini exposed to the cell’s exterior at the cell surface. Each of the shed forms contain putative functional motifs characteristic of ECTO-NOX (ENOX) proteins despite only minimal sequence identity. Our findings identify arNOX as having functional characteristics of ENOX proteins and the TM9 superfamily of proteins as the genetic origins of the five known arNOX isoforms present in human sera, plasma and other body fluids1.展开更多

T...Introduction After the birth of the Universal Declaration of Human Rights (UDHR), "universal human rights" became a novel formal legal term both in the field of jurisprudence and in the international community. The notion of "universal human rights" indicates the ideal of "all human rights for all." As the provision in Article 2 of the UDHR stated: "Everyone is entitled to all the rights and freedoms set forth in this Declaration, without distinction of any kind, such as race, color, sex, language, religion, politi cal or other opinion, national or social origin, property, birth or other status." However, some nonWestern govern ment officials and intellectuals have expressed doubts about the justifi ability of the term, which seems only to be a reflection of unique Western culture rather than Asian or Arabian ones. At the Vienna World Human Rights Conference, many heads of state said that universal human rights cannot be compatible with nonWest em culture. Even Lee Kuan Yew, the former leader of Singapore, declared in 1996: "Asian values are universal values. European values are European values.''~ This statement is obviously a rejection of the idea that human rights are universal. In contrast, universal rights extremists and human rights activists and NGOs, such as Amnesty International and Human Rights Watch, try to propagandize unified international human rights standards and international human rights re gimes. The debate continues from the diplomatic field to the academic field. But, in the foreseeable future,展开更多

This study aimed to explore the association between human leukocyte antigen-antigen D-related (HLA-DR) expression and multidrug-resistant infection in patients with SAP. A total of 24 SAP patients who were admitted to Nanjing Drum Tower Hospital between May 2015 and December 2016 were enrolled in the study. The percentages of CD4^+, CD8^+, natural killer (NK), and HLA-DR (CD14+) cells and the CD4^+/CD8^+ cell ratio on days 1, 7, 14, and 28 after admission were determined by flow cytometry. Eighteen patients presented with the symptoms of infection. Among them, 55.6% patients (10/18) developed MDR infection. The most common causative MDR organisms were Enterobacter cloacae and Acinetobacter baumannii. The CD4+/CD8+ cell ratio and the percentage of NK cells were similar between patients with non-MDR and patients with MDR infections. In patients without infection, the HLA-DR percentage was maintained at a high level throughout the 28 days. Compared to the patients without any infection, the HLA-DR percentage in patients with non-MDR infection was reduced on day 1 but increased and reached similar levels on day 28. In patients with MDR infection, the HLA-DR percentage remained below normal levels at all-time points. It was concluded that persistent down-regulation of HLA-DR expression is associated with MDR bacterial infection in patients with SAP.展开更多

For this reason, there is nothing better than to turn to ethics in order to "moralise" the system and the world, when the numerous news of fraud, injustice, and scandals are a part of everyday life in the business world and in our society. But, is this the role of ethics? Can we reduce the aim of ethics to a mere technique? In this paper, it is argued that ethics needs to be replaced in the epistemological scale of knowledge, where until now it has occupied a place at the top. Ethics needs to be repositioned in a different level of knowledge where we may find the roots of its foundation. It is also discussed that it is at the core of being that the experience of the action takes place and develops and in it, ethics takes root. Furthermore, it is suggested that understanding ethics from this point of view presupposes a new ethos around a relational poietics which privileges inter-subjectivity, self-creation, and an active and dynamic construction of the human and of the world.展开更多

Experimental data revealed that mu rhythm suppression was exhibited in the mirror neuron system when subjects observed both real and drawn hand motion. Moreover, the mu rhythm recorded at the F3, Fz, F4, and Pz poles was significantly suppressed while observing both stimulus types, but no obvious mu suppression occurred at the O1, 02 and 03 poles. These results suggest that the observation of drawings of human hand actions can activate the human mirror neuron system. This evidence supports the hypothesis that the mirror neuron system may be involved in intransitively abstract action understanding.展开更多

We have detected KLK5 levels in ovarian cancer serum to ensure that our sandwich ELISA measurement to have high sensitivity and specificity. The ranges of linearity reached by the standard curves of the newly developed ELISA were 0.45 ng/mL to 125 ng/mL. The detection limit of the method, defined as the concentration of KLK5 can be distinguished, was 0.20 ng/mL. Median serum KLK5 levels were 3.77 ng/mL and 0.86 ng/mL in ovarian cancer patients and normal female, respectively (P ELISA assay for KLK5. Our preliminary findings prompt that KLK5 may be a new potential biomarker for the diagnosis and prognosis in patients with ovarian.
文摘The aim of this work is to present the central role of interpersonal relations in Human Systems Therapy(HST).Psychotherapies can be classified as(a)down-top therapies,such as individual therapies following reductionism,namely influencing the whole(behavior)through the intra-psychic parts,(b)top-down or holistic therapies,such as family therapies influencing the parts(individuals)through the whole family,and(c)the combination of down-top and top-down.Emotionally Focused Therapy(EFT)and Multisystemic Therapy(MST)act on two levels that influence each other,namely the individuals and their relations.This is also applied,more or less,on relational and interpersonal therapies.When there is an intervention in two interacting parts or levels,then the result of the intervention is more than additive and more effective.When the levels are more than two,then the effectiveness is expected to be even higher.This is the case of Human Systems Therapy(HST),which is applied intrapsychically,on interpersonal relations and on family and/or larger systems,with interpersonal relations having a central role.HST is based on general systems principles and it constitutes a multilevel approach:(a)a definition of a human system,(b)epistemology,(c)a model of human systems personality/intelligence,(d)an increase in order and variety.Besides,HST includes a large number of techniques.Empirical support of HST effectiveness shows that(a)after seven sessions with schizophrenics,39%of psychotic symptoms are reduced,(b)after eight sessions with hashish adolescent users,all users stop the use completely,and(c)9 out of 11 psychiatric non-psychotic cases(81%),after four sessions,become non-psychiatric ones(treated).
文摘Age-related NADH oxidase (arNOX = ENOX3) proteins are superoxide-generating cell surface oxidases that increase in activity with age beginning at about 30 y. A soluble and truncated exfoliated form of the activity is present in blood and other body fluids. The activity was purified to apparent homogeneity from human urine and resolved by 2-D gel electrophoresis into a series of 24 to 32 kDa components of low isoelectric point. The purified proteins were resistant both to N-terminal sequencing and trypsin cleavage. Cleavage with pepsin revealed peptides corresponding to the TM9 family of transmembrane proteins. Peptide antisera raised to all five members of the human TM9 family sequentially blocked the arNOX activity of human saliva and sera. The soluble truncated N-terminus of the human homolog TM9SF4 was expressed in bacteria. The recombinant protein was characterized biochemically and exhibited ar-NOX activity. The findings identify five arNOX isoforms each of which correspond to one of the five known TM9 family members. The exfoliated soluble arNOX forms are derived from the 24 to 32 kDa N-termini exposed to the cell’s exterior at the cell surface. Each of the shed forms contain putative functional motifs characteristic of ECTO-NOX (ENOX) proteins despite only minimal sequence identity. Our findings identify arNOX as having functional characteristics of ENOX proteins and the TM9 superfamily of proteins as the genetic origins of the five known arNOX isoforms present in human sera, plasma and other body fluids1.
文摘The Little Prince created by French aristocrat,writer and poet Antoine de Saint–Exupéry not only permeates French romanticism in the 19^(th) century,but implies philosophy of life.As one of the most popular books in the world,it shows that adults or modern people should learn from children to keep kind,imagitive,faithful and so on instead of being worldly-wise,and expresses sincere feelings based on imaginative descriptions.In addition,the movie version with new elements directed by Mark Osborne conquered the world again from a new perspective.And then,a kind of conflicting or harmonious relation is revealed no matter in the original work or in the movie version.However,today’s relationships between people tend to be more complex and less pure since the development of science and technology,artificial intelligence and We Media have become all the rage.Thus,it focuses on revealing the conflict and harmony of individuals’relations through these images in the original work and through a couple of new elements in the 21^(st) century in the movie version to show the transformation from the conflict to harmony.
文摘Introduction After the birth of the Universal Declaration of Human Rights (UDHR), "universal human rights" became a novel formal legal term both in the field of jurisprudence and in the international community. The notion of "universal human rights" indicates the ideal of "all human rights for all." As the provision in Article 2 of the UDHR stated: "Everyone is entitled to all the rights and freedoms set forth in this Declaration, without distinction of any kind, such as race, color, sex, language, religion, politi cal or other opinion, national or social origin, property, birth or other status." However, some nonWestern govern ment officials and intellectuals have expressed doubts about the justifi ability of the term, which seems only to be a reflection of unique Western culture rather than Asian or Arabian ones. At the Vienna World Human Rights Conference, many heads of state said that universal human rights cannot be compatible with nonWest em culture. Even Lee Kuan Yew, the former leader of Singapore, declared in 1996: "Asian values are universal values. European values are European values.''~ This statement is obviously a rejection of the idea that human rights are universal. In contrast, universal rights extremists and human rights activists and NGOs, such as Amnesty International and Human Rights Watch, try to propagandize unified international human rights standards and international human rights re gimes. The debate continues from the diplomatic field to the academic field. But, in the foreseeable future,
文摘Emily Dickenson’s poems have long enjoyed considerable acclaims from critics and common readers for her delicate and profound writing of life and death,love,nature,etc.Her short poem“My Life had stood—a Loaded Gun”is one receiving relatively few academic discussion.Among the rather few existent studies,many discuss Dickenson’s feminist ideas,religious bewilderment,literary creation views or even personal feeling in this poem.This article,instead,gives an interpretation of this poem from an ecocritical perspective.It points out that Emily Dickenson in this poem expresses her condemnation on human’s cruelty and indiffer?ence to nature.After a thorough interpretation of Dickenson’s reflection on human-nature relationship in this poem,the article fur?ther explores Dickenson’s attitudes toward nature through her personal writing background and clues in her other works to support this interpretation.

文摘Land cover in the Chinese Loess Plateau has undergone dramatic changes since the late 1980s.Revealing the trend in land cover change and eco-environmental quality response of different geomorphic units in this stage is a realistic requirement for promoting sustainable development of the Chinese Loess Plateau.Based on the data of geomorphic units and land cover in 1990,2000,2010 and 2018 of the Chinese Loess Plateau,we studied the trend of land cover change and eco-environmental quality response of different geomorphic units by using a significance index of land cover change,a proportion index of land cover change and an eco-environmental response model.The results indicated that from 1990 to 2018,the areas of forestland and construction land substantially increased,whereas those of cropland,grassland,wetland and unused land considerably decreased.Land cover change exhibited large geomorphic differences,and the main conversion of land cover was from cropland into other land types.Unstable trend of land cover change in the loess tablelands and sandy loess hills declined,whereas the unstable trends in the other geomorphic units enhanced.Eco-environmental quality varied among different geomorphic units.The expansion of construction land and degradation of forestland,grassland and wetland resulted in the deterioration of eco-environmental quality.The conversion of cropland and unused land into forestland and grassland,and the conversion of grassland into forestland were the main factors that drove the improvement of eco-environmental quality.The findings of this study may provide theoretical reference and support decision making for the optimization of land use structure and the improvement of eco-environmental quality on the Chinese Loess Plateau.

文摘Multidrug-resistant (MDR) bacterial infection is a common complication of severe acute pancreatitis (SAP). This study aimed to explore the association between human leukocyte antigen-antigen D-related (HLA-DR) expression and multidrug-resistant infection in patients with SAP. A total of 24 SAP patients who were admitted to Nanjing Drum Tower Hospital between May 2015 and December 2016 were enrolled in the study. The percentages of CD4^+, CD8^+, natural killer (NK), and HLA-DR (CD14+) cells and the CD4^+/CD8^+ cell ratio on days 1, 7, 14, and 28 after admission were determined by flow cytometry. Eighteen patients presented with the symptoms of infection. Among them, 55.6% patients (10/18) developed MDR infection. The most common causative MDR organisms were Enterobacter cloacae and Acinetobacter baumannii. The CD4+/CD8+ cell ratio and the percentage of NK cells were similar between patients with non-MDR and patients with MDR infections. In patients without infection, the HLA-DR percentage was maintained at a high level throughout the 28 days. Compared to the patients without any infection, the HLA-DR percentage in patients with non-MDR infection was reduced on day 1 but increased and reached similar levels on day 28. In patients with MDR infection, the HLA-DR percentage remained below normal levels at all-time points. It was concluded that persistent down-regulation of HLA-DR expression is associated with MDR bacterial infection in patients with SAP.
文摘This paper will attempt to clarify the clear tendency, in our contemporary world, to look at ethics as something that "cures" all wrongs, all unbalance, and all evils from the political, environmental, to the business ones. For this reason, there is nothing better than to turn to ethics in order to "moralise" the system and the world, when the numerous news of fraud, injustice, and scandals are a part of everyday life in the business world and in our society. But, is this the role of ethics? Can we reduce the aim of ethics to a mere technique? In this paper, it is argued that ethics needs to be replaced in the epistemological scale of knowledge, where until now it has occupied a place at the top. Ethics needs to be repositioned in a different level of knowledge where we may find the roots of its foundation. It is also discussed that it is at the core of being that the experience of the action takes place and develops and in it, ethics takes root. Furthermore, it is suggested that understanding ethics from this point of view presupposes a new ethos around a relational poietics which privileges inter-subjectivity, self-creation, and an active and dynamic construction of the human and of the world.

文摘The present study used electroencephalography to examine mu rhythm suppression (a putative index of human mirror neuron system activation) at frontal sites (F3, Fz and F4), central sites (C3, Cz and C4), parietal sites (P3, Pz and P4) and occipital sites (O1 and O2), while subjects observed real hand motion (real hand motion condition) and illustrative depictions of hand motion (drawn hand motion condition). Experimental data revealed that mu rhythm suppression was exhibited in the mirror neuron system when subjects observed both real and drawn hand motion. Moreover, the mu rhythm recorded at the F3, Fz, F4, and Pz poles was significantly suppressed while observing both stimulus types, but no obvious mu suppression occurred at the O1, 02 and 03 poles. These results suggest that the observation of drawings of human hand actions can activate the human mirror neuron system. This evidence supports the hypothesis that the mirror neuron system may be involved in intransitively abstract action understanding.
