陆九渊心学中的“心”、“本心”——陆九渊心学九辨之六     

涂宗流 《荆门职业技术学院学报》2000,15(2):79-85

陆九渊心学中有“心”和“本心”两个概念。“心”是以“思”为职的人体器官,即现代心理学所说的“人脑”;“本心”就是“仁义之心”,是现实的伦理关系以及传统伦理道德的言传身教在“心”(人脑)中的反映,属心理现象。《陆九渊集》中“人非木石,安得无心”、“心一也”中的“心”,是指“于五官最尊大”的“心”(人脑);“本心”、“良心”、“赤子之心”,是指属于心理现象的“仁义之心”。  相似文献   

Brain metastases of melanoma mechanisms of attack on their defence system by engineered stem cells in the microenvironment   总被引：1，自引：1，他引：0  

Dimitrov BD  Atanassova PA  Rachkova MI 《Journal of Zhejiang University. Science. B》2007,8(9):609-611

This report gives a better emphasis on the role of targeted effectors （e.g. a combination of 5-FC with CD-NSPCs as compared to the application of NSPCs alone） and how such delivery of pro-drug activating enzymes and other tumor-killing substances may overcome melanocytic defence system, interact with and promote the host defence and immune response modulations not only in melanoma but, potentially, in other highly-metastatic cancers.  相似文献

Brain CT image database building for computer-aided diagnosis using content-based image retrieval     

Kehong Yuan  Zhen Tian  Jiying Zou  Yanling Bai  Qingshan You 《Information processing & management》2011

Content-based image retrieval for medical images is a primary technique for computer-aided diagnosis. While it is a premise for computer-aided diagnosis system to build an efficient medical image database which is paid less attention than that it deserves. In this paper, we provide an efficient approach to develop the archives of large brain CT medical data. Medical images are securely acquired along with relevant diagnosis reports and then cleansed, validated and enhanced. Then some sophisticated image processing algorithms including image normalization and registration are applied to make sure that only corresponding anatomy regions could be compared in image matching. A vector of features is extracted by non-negative tensor factorization and associated with each image, which is essential for the content-based image retrieval. Our experiments prove the efficiency and promising prospect of this database building method for computer-aided diagnosis system. The brain CT image database we built could provide radiologists with a convenient access to retrieve pre-diagnosed, validated and highly relevant examples based on image content and obtain computer-aided diagnosis.  相似文献

Brain natriuretic peptide and optimal management of heart failure     

Li N  Wang JA 《Journal of Zhejiang University. Science. B》2005,6(9):877-884

BRAIN NATRIURETIC PEPTIDE Several studies demonstrated that the heart is an endocrine organ (Henry and Pearce, 1956; Kisch, 1956; de Bold, 1985; de Bold et al., 1981; 1996; 2001). Atrial natriuretic peptide (ANP) was the first cardiac hormone identified in 1984 (Kangawa et al., 1984; de Bold et al., 1981). Later on, a new com- pound from pig brain was found, which had similar natriuretic and diuretic effects as ANP (Sudoh et al., 1988). This peptide was named brain (B-type) natr…  相似文献   

A remote control training system for rat navigation in complicated environment

INTRODUCTION Electrical stimulation in the animal brain is an indispensable means to investigate brain mechanisms in many experimental setups. However, the cable connections between the stimulation instruments and the animal brain always limit the animal’s freedom of movement and thereby cause entwisting and breaking of the cables, especially in freely moving animal ex-periments. In order to solve this problem, telemetry systems have been designed to deliver the stimulationsignals as sub…  相似文献   

Role of ethanol on aluminum induced biochemical changes on rat brain     

Parsunpriya Nayak  Subir Kumar Das  D. M. Vasudevan 《Indian journal of clinical biochemistry : IJCB》2006,21(2):53-57

Aluminum and alcohol, both are well-accepted neurotoxin. The plausible mechanisms for their neurotoxicity are also common. Therefore, the effect of ethanol on aluminum induced biochemical changes in rat brain is being studied. In the present study, ethanol exposure significantly affected the aluminum and protein content of brain. The activities of acid phosphatase and alkaline phosphatase were also changed. Aluminum exposure, on the other hand, contributed significantly in the alterations of aluminum content, acid phosphatase acivity and aspartate aminotransferase activity. Though ethanol co-exposure significantly influenced the aluminum load of brain, the interactions of these two neurotoxins were found to be significant only in case of acid phosphatase activity of brain. Therefore, it can be suggested that general neurotoxicity produced by aluminum is not modified by ethanol. However, the aluminum load caused by aluminum exposure, may be influenced by ethanol co-exposure.  相似文献   

Increased expression of aquaporin-4 in human traumatic brain injury and brain tumors   总被引：15，自引：0，他引：15  

Hu H  Yao HT  Zhang WP  Zhang L  Ding W  Zhang SH  Chen Z  Wei EQ 《Journal of Zhejiang University. Science. B》2005,6(1):33-37

Objective:To characterize the expression of aquaporin-4(AQP4),one of the aquaporins(AQPs),in human brainspecimens from patients with traumatic brain injury or brain tumors.Methods:Nineteen hnman brain specimens were obtahledfrom the patients with traumatic brain injury,brain tumors,benign meningioma or early stage hemorrhagic stroke.MRI or CTimaging was used to assess brain edema.Hematoxylin and eosm staining were used to evaluate cell damage,Immunohistochem-istry was used to detect the AQP4 expression.Results:AQP4 expression was increased from 15 h to at least 8 d after injury.AQP4immunoreactivity was strong around astrocytomas,ganglioglioma and metastatic adenocarcinoma.However,AQP4 immunore-activity was only found in the centers of astrocytomas and ganglioglioma,but not in metastatic adenocarcinoma derived from lung.Conclusion:AQP4 expression increases in human brains alter traumatic brain injury,within brain-derived tumors,and aroundbrain tumors.  相似文献
