Title: Negative electrode for lithium secondary battery, preparing method thereof, and lithium secondary battery comprising the same
Inventor: CHAE OH BYONG
IPC: H01M4/13
Filed: 2018-04-11
Abstract: The present invention relates to a negative electrode for a lithium secondary battery, a method for manufacturing the negative electrode, and a lithium secondary battery including the negative electrode. Specifically, since the lithium metal ions are diffused in a negative electrode active material layer by pre-lithiation, the negative electrode of the present invention can reduce the initial irreversibility of the negative electrode. Since the negative electrode active material layer in which the lithium metal ions are diffused includes a plurality of line-shaped recesses, when the lithium secondary battery is manufactured later, the recesses hold an electrolyte well, thereby enhancing the impregnation of the electrolyte. Ultimately, the electrochemical performance of the lithium secondary battery can be enhanced.

Title: Method for diagnosis of Alzheimer's dementia using analysis of bacteria metagenome
Inventor: YOON KEUN KIM
IPC: C12Q1/6895
Filed: 2018-05-28
Abstract: The present invention relates to a method of diagnosing Alzheimer′s disease using bacterial metagenomic analysis and, more specifically, to a method of diagnosing Alzheimer′s disease or mild cognitive impairments by performing bacterial metagenomic analysis using a sample derived from a normal person and a test subject and analyzing increase/decrease in a content of extracellular vesicles originated from particular bacteria. Extracellular vesicles secreted from the bacteria existing in an environment may be absorbed into a body and penetrate brain tissues to directly influence cognitive functions so as to cause Alzheimer′s disease, and Alzheimer′s disease is difficult to diagnose at an early stage before symptoms appear and thus is difficult to treat effectively. Accordingly, through the metagenomic analysis of extracellular vesicles derived from bacteria using a sample derived from a human body, the risk of mild cognitive impairments and Alzheimer′s disease can be predicted in advance to delay or prevent the onset of the disease through appropriate care in a group at the risk of Alzheimer′s disease through early diagnosis and prediction. Furthermore, the method of the present invention enables an early diagnosis of the disease even after the onset of the disease, thereby reducing the onset rate of Alzheimer′s disease and increasing treatment effects thereof.
