PubMed - What Is It, And What Can I Learn About There?


Pubmed is referred to throughout the pages of this website. It is an online resource of published medical studies that are freely available to the public, and I have taken the time to select information from this resource as it pertains to you, your health, and glutathione enhancement, and provide access for you on the pages of this site.

According to the Pub Med Official Website, (this link opens in a new window):

Pubmed, available via the NCBI Entrez retrieval system, was developed by the National Center for Biotechnology Information (NCBI) at the National Library of Medicine (NLM), the world’s largest medical library, located at the U.S. National Institutes of Health (NIH). 

PubMed Entrez is the text-based search and retrieval system used at NCBI for services including PubMed, Nucleotide and Protein Sequences, Protein Structures, Complete Genomes, Taxonomy, OMIM, and many others. PubMed provides access to citations from biomedical literature.”

Medline is a term you will often hear associated with PubMed. According to the official Medline website, (this link opens in a new window):

MEDLINE® (Medical Literature Analysis and Retrieval System Online) is the U.S. National Library of Medicine's® (NLM) premier bibliographic database that contains over 16 million references to journal articles in life sciences with a concentration on biomedicine. A distinctive feature of MEDLINE is that the records are indexed with NLM's Medical Subject Headings (MeSH®).

Medline is the largest component of PubMed, the freely accessible online database of biomedical journal citations and abstracts created by the U.S. National Library of Medicine (NLM®). Approximately 5,200 journals published in the United States and more than 80 other countries have been selected and are currently indexed for MEDLINE.

For more information, please see a fact sheet entitled What’s the Difference between Medline and PubMed? (this link opens in a new window).

This may bring up some additional supplementary questions related to the subject of Pub Med.

Who is the US National Institutes of Health?

According to the National Institutes of Health official website, (this link opens in a new window):

“The National Institutes of Health (NIH), a part of the U.S. Department of Health and Human Services, is the primary Federal agency for conducting and supporting medical research.

Helping to lead the way toward important medical discoveries that improve people's health and save lives, NIH scientists investigate ways to prevent disease as well as the causes, treatments, and even cures for common and rare diseases. Composed of 27 Institutes and Centers, the NIH provides leadership and financial support to researchers in every state and throughout the world.

For over a century, the National Institutes of Health has played an important role in improving the health of the nation. The NIH traces its roots to 1887 with the creation of the Laboratory of Hygiene at the Marine Hospital in Staten Island, NY. The NIH is an agency of the U.S. Department of Health and Human Services. With the headquarters in Bethesda, Maryland, the NIH has more than 18,000 employees on the main campus and at satellite sites across the country.

With the support of the American people, the NIH annually invests over $28 billion in medical research. More than 83% of the NIH's funding is awarded through almost 50,000 competitive grants to more than 325,000 researchers at over 3,000 universities, medical schools, and other research institutions in every state and around the world.

About 10% of the NIH's budget supports projects conducted by nearly 6,000 scientists in its own laboratories, most of which are on the NIH campus in Bethesda, Maryland.”

The NIH sponsors PubMed, which is a service of the US National Library of Medicine and the National Institutes of Health.


What is NCBI?

NCBI stands for the National Center for Biotechnology Information, and according to the NCBI website, (this link opens in a new window):

NCBI was “Established in 1988 as a national resource for molecular biology information, NCBI creates public databases, conducts research in computational biology, develops software tools for analyzing genome data, and disseminates biomedical information - all for the better understanding of molecular processes affecting human health and disease.”





In conclusion, PubMed, the National Center for Biotechnology Information (NCBI), the National Library of Medicine (NLM), the U.S. National Institutes of Health (NIH), and Medline, are all essential components of a related subject - the focus is on funding, conducting, and publishing medical research from around the world so that you and I have free access to it.

PubMed Why do I bring all of this information about PubMed to you? The focus of this site is on disease prevention and treatment with glutathione.

There are now over 95,000 published articles available on PubMed about this substance, and yet many have never heard of glutathione.

I bring this information to you to familiarize you with the subject of glutathione, and also to give you access to information that you may want to discuss with your doctor if you decide to use glutathione enhancement as part of your medical treatment. The information is here for you to use.

Please see my Medical Disclaimer for more information about my role in bringing this information to you.

For published studies on PubMed about the subject of oxidative stress and glutathione for a particular disease state or area of health concern, please follow the links below. I will go from A to Z, and to keep up with the latest pages I add, please subscribe to my blog with the orange button on the left.

You can also find more general information by disease state on the What Is Disease? page.
