Peptide Identification Using Tandem Mass Spectrometry01:33

Peptide Identification Using Tandem Mass Spectrometry

6.4K
Tandem mass spectrometry, also known as MS/MS or MS2, is an analytical technique that employs two mass analyzers. Essentially it is a series of mass spectrometers that helps isolate a particular biomolecule and then helps study its chemical properties.
This technique helps gather information regarding the protein from which the peptide was obtained and to study the peptides’ amino acid sequence. Identifying peptides from a complex mixture is an important component of the growing field of...

In-situ Hybridization02:31

In-situ Hybridization

9.2K
In situ hybridization (ISH) is a technique used to detect and localize specific DNA or RNA molecules in cells, tissue, or tissue sections using a labeled probe. The technique was first used in 1969 for the investigation of nucleic acids. It is currently an essential tool in scientific research and clinical settings, especially for diagnostic purposes.
Types of probes and labels
A probe is a complementary strand of DNA or RNA that binds to corresponding nucleotide sequences in a cell. Many...

Data Validation01:03

Data Validation

5.0K
Data validation is an essential part of a comprehensive assessment. Validation is confirming or verifying and opening the door to gathering more assessment data as it clarifies vague or unclear data. The process of checking and verifying the collected information is called data validation. The primary purpose of data validation is to ensure data is as free from error, bias, and misinterpretation as possible.
Nursing assessment guides are generally based on holistic models rather than medical...

Genomics

36.2K
Genomics is the science of genomes: it is the study of all the genetic material of an organism. In humans, the genome consists of information carried in 23 pairs of chromosomes in the nucleus, as well as mitochondrial DNA. In genomics, both coding and non-coding DNA is sequenced and analyzed. Genomics allows a better understanding of all living things, their evolution, and their diversity. It has a myriad of uses: for example, to build phylogenetic trees, to improve productivity and...

Formulating and Validating Nursing Diagnosis I01:26

Formulating and Validating Nursing Diagnosis I

2.6K
A nursing diagnosis is written when the nurse recognizes a cluster of essential patient data indicating health problems treated with independent nursing interventions. The standardized terminologies of a nursing diagnosis help nurses identify and treat patients' problems. Every electronic health record that uses nursing diagnosis must employ standard diagnostic terminology. Developing an efficient, individualized care plan begins with accurate nursing diagnoses.
There are thirteen domains...

Area of Science:

  • Biomedical Informatics
  • Epidemiology
  • Population Health Research

Background:

  • Integrating diverse study designs strengthens evidence in population health research.
  • Evidence triangulation faces challenges in harmonizing heterogeneous data and prioritizing information.
  • Systematic identification and integration of relevant evidence are crucial but complex.

Purpose of the Study:

  • To present Annotated Semantic Queries (ASQ), a natural language interface for EpiGraphDB.
  • To enable users to extract and investigate evidence supporting or contradicting claims from text.
  • To facilitate evidence triangulation and interpretation for rapid literature review.

Main Methods:

  • ASQ is a natural language query interface to integrated biomedical entities and epidemiological evidence in EpiGraphDB.
  • It allows users to extract "claims" from unstructured text.
  • ASQ implements strategies for harmonizing biomedical entities and evidence from various sources.

Main Results:

  • ASQ enables users to investigate evidence supporting, contradicting, or supplementing extracted claims.
  • The system facilitates the harmonization of biomedical entities across different taxonomies.
  • It supports the integration of evidence from diverse sources for robust interpretation.

Conclusions:

  • ASQ has the potential to significantly aid in the rapid review of preprints, grant applications, and peer-reviewed articles.
  • The tool enhances evidence triangulation by harmonizing disparate data.
  • ASQ improves the interpretation of complex biomedical and epidemiological evidence.
