Digital acquisition and analysis of sleep data has become more common over the past 20 years. Many investigators have developed strategies to record and analyze sleep in a quantitative way. Initially, digital recording and analysis were restricted by technical limitations. With current technology, the technical limitations of computer acquisition, data storage, and analysis are less constrainin...

It would be nice if we could talk about sleep and memory as if there were only one type of memory and one type of sleep. But this is far from the case. Sleep and memory each comes in many forms, and furthermore, memories can go through multiple forms of post-encoding processing that must be individually addressed. Finally, sleep stages per se do not affect memories. Rather, the neuromodulatory ...

Background: Nowadays long non-coding RNAs are known as interesting functional part of the transcriptome. LncRNA SNHG6 was reported to be expressed more in breast cancer tissues than non-tumor ones. As a frequent cancer among women, breast cancer treatment needs applied biomarkers for fast prognosis and diagnosis. SNHG6 RNA and its splice variants could be considered as molecula...

In this paper, an automatic support system for brain tumor stage classification using learning machine and for detecting brain tumor during early stages using fuzzy clustering methods is proposed. The fuzzy clustering method is a segmentation technique presented to segment the Magnetic Resonance images for detecting the Brain Tumor during early stages and for examining anatomical structures. Fa...

BACKGROUND Wilms' tumor is an emberyonal tumor arising from remnants of immature renal tissue. Her2/neu is an onco-protein which mediates cellular proliferation, differentiation and survival. METHODS In the current study, we analyzed Her2/neu expression in 40 Wilms' tumors. The clinico-demographic data of 40 patients with Wilms' tumor were retrieved. Immunohistochemical staining for HER2/neu ...

Chronic pruritus is a debilitating condition with numerous etiologies. Many patients suffer from nocturnal pruritus, which can decrease quality of life and affect mortality in hemodialysis patients. Nocturnal pruritus may occur in all sleep stages but is most prevalent in stages N1 and N2. Further research is needed to elucidate the pathophysiology of nocturnal itch, which will aid in the devel...

A system for computer-assisted encoding, tabulation and analysis of visually scored sleep data is presented. The main features of the system are: (1) The use of computer-readable optical scan sheets for direct encoding of the sleep data. This eliminates the need for a separate transcription and/or key-punching operation. (2) The development of a visually scored data base, organized by NREM and ...

Tumor is defined as a kind of chronic diseases by the World Health Organization. The integrative traditional Chinese and western medicine works well on treatment tumors, even in advanced patients or with recurring metastatic tumor. However, pathogenic mechanism tumors still unclear. Therefore, based 19th pathogenesis Yellow Emperor's Internal Class that "Diseases producing liquid clear chill al...

BACKGROUND Malignant ovarian germ cell tumor is a rare type of disease, which generally has a good prognosis due to the high chemosensitivity of this type of tumor. Fertility preservation is an important issue because malignant ovarian germ cell tumor commonly affects young women. Although conservation is the standard for early stage, it becomes more debatable as the disease progresses to more ...
