The relationship between microbes and human health has always been concerned. In recent years, the study of gut microbiota has become the current hotspot in life sciences and medical research with the application of high-throughput sequencing and metagenomics, more and more scientific researchers have forced on this field. Scientists find that gut microbiota can participate in and regulate the body's physiological functions, affect weight and digestion, defense a variety of diseases caused by the exogenous infections. In addition, it is closely related with some endogenous diseases, like endocrine disease, intestinal disease, neurological disease, cancer and so on. One article, nam......2017-07-07

Pleural mesothelioma is the tumor that originated in the peritoneal mesothelial cell. Pleural mesothelioma is related with asbestos exposure. There are significant differences in the incidence of pleural mesothelioma in different countries, this is mainly related to the asbestos consumption of these countries over the past several decades. The mortality rate of pleural mesothelioma has a rising tendency in recent years.The common first symptom of pleural mesothelioma is chest pain, cough and shortness of breath. There are also symptoms of fever, sweating or joint pain. Most patients have a lot of pleural effusion and short of breath, the patients that without mass of pleural effusion w......2017-07-07

‍‍‍Since September 2004, "Nature" published the first article on the results of RNA interference by American scientist Andrew Z. Fire and Craig C. Mello et al., The small RNA playsthe important regulatory role in biological life activities. Every day there are articles on relation of the various small RNA and body development. And smart biotechnology companies are also at an amazing rate to actively use RNAi technology fordrug screening,Cloud-Clone Corp. has been launched for the lentivirus and adenovirus expression system, The RNAi is one of the important sever of customer.RNAi is a specific gene silencing technology,which is mediated by double-stranded RNA (dsRNA).......2017-07-07

Gene is regarded as the most important information carrier of organism. It stores all the genetic information of organisms, determines the biological characteristics, classification, life cycle and other characteristics. However, genes don’t directly join in the regulation of life activities. In higher organisms, DNA is served as template to get RNA by transcription, some RNA guide making protein by translation, the protein is directly joined in kinds of life activities. RNA play an important role connecting gene and protein. The RNA will directly or indirectly take part in the process of protein translation, gene regulation and nucleic acid cutting. All of these support that the stu......2017-07-07

Cells have to split the proliferation of the way. Single-celled organisms, which produce new members by cell division. Multicellular organisms, which produce new cells in a split way to supplement the aging or death cells in the body. Mitosis is the main mode for cell divisionof eukaryotes. Cell proliferation is the basis of organism growth, development, breeding, genetics, and so on, so cell proliferation detection has always been a hot research topic.Conventional cell proliferation detection techniques include the following:(1)Marker protein detection by WB and so on. PCNAis proliferating cell nuclear antigen, it plays an important role in starting DNA replication and cell prolifera......2017-07-07

It is known that the blood routing testsand one of them is C reactive protein(CRP) test. But who knows what CRP and its clinical significanceis?CRP is a protein which is produced by liver, ithas 224 amino acids and themonomer molecular mass of 25kDa. CRP can bind C polysaccharide on the surface of bacteria to form a complex to activate the classical complement pathway, which allows body to obtain the ability by nonspecific immune pathway to resist various bacteria, fungi and parasites, etc. In normal individuals, the CRP level in blood ranges from 800to 80000ug/L. And for organism with acute infection, serious injury or malignant tumor, the CRP level will rise dramatically in the next ......2017-07-07
