Western Blot
The western blot (sometimes called the protein immunoblot), or western blotting, is a widely used analytical technique in molecular biology and immunogenetics to detect specific proteins in a sample of tissue homogenate or extract. Besides detecting the proteins, this technique is also utilized to visualize, distinguish, and quantify the different proteins in a complicated protein combination. Western blot technique uses three elements to achieve its task of separating a specific protein from a complex: separation by size, transfer of protein to a solid support, and marking target protein using a primary and secondary antibody to visualize. A synthetic or animal-derived antibody (known as the primary antibody) is created that recognizes and binds to a specific target protein. The electrophoresis membrane is washed in a solution containing the primary antibody, before excess antibody is washed off. A secondary antibody is added which recognizes and binds to the primary antibody ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
PubPeer
PubPeer is a website that allows users to discuss and review scientific research after publication, i.e. post-publication peer review. The site has served as a whistleblowing platform, in that it highlighted shortcomings in several high-profile papers, in some cases leading to retractions and to accusations of scientific fraud, as noted by Retraction Watch. Contrary to most platforms, it allows anonymous post-publication commenting, a controversial feature which is the main factor for its success. Consequently, accusations of libel have been levelled at some of PubPeer's users; correspondingly the website now requires commentators to use only facts that can be publicly verified. See also * Journal club * JournalReview.org * Publons Publons was a commercial website that provided a free service for academics to track, verify, and showcase their peer review and editorial contributions for academic journals. It was launched in 2012 and was bought by Clarivate in 2017. It claime . ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Retraction Watch
Retraction Watch is a blog that reports on retractions of scientific papers and on related topics. The blog was launched in August 2010 and is produced by science writers Ivan Oransky (Former Vice President, Editorial ''Medscape'') and Adam Marcus (editor of ''Gastroenterology & Endoscopy News''). Its parent organization is the Center for Scientific Integrity. Scope Oransky and Marcus were motivated to launch ''Retraction Watch'' to increase the transparency of the retraction process. They observed that retractions of papers generally are not announced, that the reasons for retractions are not publicized, and that other researchers or the public who are unaware of the retraction may make decisions based on invalid results. Oransky described an example of a paper published in ''Proceedings of the National Academy of Sciences'' which reported a potential role for a drug against some types of breast cancers. Although the paper was later retracted, its retraction was not reported ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Case Western Reserve University School Of Medicine
Case Western Reserve School of Medicine (CWRU SOM, CaseMed) is the medical school of Case Western Reserve University, a private research university in Cleveland, Ohio. It is the largest biomedical research center in Ohio. History On November 1, 1843, under President George Edmond Pierce, five faculty members including Jared Potter Kirtland and John Delamater, and sixty-seven students began the first medical lectures at the Medical Department of Western Reserve College (also known as the Cleveland Medical College) in Hudson, Ohio. Kirtland and Delamater had previously been instructors at a medical college started in 1834, the Medical Department of Willoughby University of Lake Erie, which had closed in 1843 due to faculty disagreements. Other faculty from that Medical Department went on to found Willoughby Medical College of Columbus, a precursor to the Ohio State University College of Medicine. Women in Medicine In 1852, the medical school became the second in the U.S. t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Image Manipulation Discovered By Elisabeth Bik
An image is a visual representation of something. It can be two-dimensional, three-dimensional, or somehow otherwise feed into the visual system to convey information. An image can be an artifact, such as a photograph or other two-dimensional picture, that resembles a subject. In the context of signal processing, an image is a distributed amplitude of color(s). In optics, the term “image” may refer specifically to a 2D image. An image does not have to use the entire visual system to be a visual representation. A popular example of this is of a greyscale image, which uses the visual system's sensitivity to brightness across all wavelengths, without taking into account different colors. A black and white visual representation of something is still an image, even though it does not make full use of the visual system's capabilities. Images are typically still, but in some cases can be moving or animated. Characteristics Images may be two or three-dimensional, such as a pho ...

Sea Lion
Sea lions are pinnipeds characterized by external ear flaps, long foreflippers, the ability to walk on all fours, short and thick hair, and a big chest and belly. Together with the fur seals, they make up the family Otariidae, eared seals. The sea lions have six extant and one extinct species (the Japanese sea lion) in five genera. Their range extends from the subarctic to tropical waters of the global ocean in both the Northern and Southern Hemispheres, with the notable exception of the northern Atlantic Ocean. They have an average lifespan of 20–30 years. A male California sea lion weighs on average about and is about long, while the female sea lion weighs and is long. The largest sea lions are Steller's sea lions, which can weigh and grow to a length of . Sea lions consume large quantities of food at a time and are known to eat about 5–8% of their body weight (about ) at a single feeding. Sea lions can move around in water and at their fastest they can reach a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Gut Microbiota
Gut microbiota, gut microbiome, or gut flora, are the microorganisms, including bacteria, archaea, fungi, and viruses that live in the digestive tracts of animals. The gastrointestinal metagenome is the aggregate of all the genomes of the gut microbiota. The gut is the main location of the human microbiome. The gut microbiota has broad impacts, including effects on colonization, resistance to pathogens, maintaining the intestinal epithelium, metabolizing dietary and pharmaceutical compounds, controlling immune function, and even behavior through the gut–brain axis. The microbial composition of the gut microbiota varies across regions of the digestive tract. The colon contains the highest microbial density recorded in any habitat on Earth, representing between 300 and 1000 different species. Bacteria are the largest and to date, best studied component and 99% of gut bacteria come from about 30 or 40 species. Up to 60% of the dry mass of feces is bacteria. Over 99% of the b ...

Oral Microbiota
Oral microbiology is the study of the microorganisms (microbiota) of the oral cavity and their interactions between oral microorganisms or with the host. The environment present in the human mouth is suited to the growth of characteristic microorganisms found there. It provides a source of water and nutrients, as well as a moderate temperature. Resident microbes of the mouth adhere to the teeth and gums to resist mechanical flushing from the mouth to stomach where acid-sensitive microbes are destroyed by hydrochloric acid. Anaerobic bacteria in the oral cavity include: ''Actinomyces'', '' Arachnia'' ('' Propionibacterium propionicus''), ''Bacteroides'', ''Bifidobacterium'', ''Eubacterium'', ''Fusobacterium'', ''Lactobacillus'', '' Leptotrichia'', ''Peptococcus'', ''Peptostreptococcus'', ''Propionibacterium'', ''Selenomonas'', ''Treponema'', and ''Veillonella''. Genera of fungi that are frequently found in the mouth include '' Candida'', ''Cladosporium'', ''Aspergillus'', ''Fusar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
