Levels of Organization01:09

Levels of Organization

145.1K
Biological organization is the classification of biological structures, ranging from atoms at the bottom of the hierarchy to the Earth's biosphere. Each level of the hierarchy represents an increase in complexity that builds upon the previous level.
Molecules Are Composed of Atoms, and Biomolecules Are Assembled from Molecules:
The most basic levels include atoms, molecules, and biomolecules. Atoms, the smallest unit of ordinary matter, are composed of a nucleus and electrons. Molecules...

Preclinical Development: Overview01:28

Preclinical Development: Overview

6.5K
Preclinical development consists of a series of tests that ensure the safety and efficacy of a new therapeutic compound before it is tested in humans. There are four main phases to this process. First, safety pharmacology tests are conducted to ensure the drug does not produce any acutely harmful effects. These tests examine parameters such as bronchoconstriction, cardiac dysrhythmias, blood pressure changes, and ataxia. Next, preliminary toxicological testing is performed to determine the...

ER Retrieval Pathway01:45

ER Retrieval Pathway

5.1K
In the secretory pathway, vesicles transport proteins from one cellular compartment to another in forward transport to deliver the protein to its correct location. Occasionally, misfolded proteins and incorrect proteins escape their original compartments, and a retrieval pathway is used to return the escaped proteins to their original compartment.
The ER uses many checkpoints to prevent the entry of incorrectly folded or a resident protein as cargo onto a transport vesicle. These mechanisms...

Clinical Trials: Overview01:11

Clinical Trials: Overview

5.5K
Clinical development focuses on how the drug will interact with the human body and encompasses four key phases of clinical trials, each serving a specific purpose in assessing the safety and effectiveness of new drugs. These phases overlap and build upon one another. Phase I involves a small group of healthy volunteers (typically 20-80 individuals) or, in cases where significant toxicity is expected, patients with the targeted disease, such as cancer or AIDS. The volunteers are tested for...

Pharmacovigilance01:19

Pharmacovigilance

2.0K
Post-marketing surveillance is a critical component of pharmaceutical regulation, often uncovering unanticipated adverse drug reactions (ADRs) once a drug is widely used over an extended period.
This process, termed pharmacovigilance, aims to detect, evaluate, and minimize harmful effects related to medication use. The data collection for pharmacovigilance depends on spontaneous reporting systems, where healthcare professionals or patients voluntarily report suspected ADRs.
In some cases, there...

Scanning Electron Microscopy01:07

Scanning Electron Microscopy

6.1K
A scanning electron microscope (SEM) is used to study the surface features of a sample by using an electron beam that scans the sample surface in a two-dimensional manner. Typically, areas between ~1 centimeter to 5 micrometers in width can be imaged. SEM can be used to image bacteria, viruses, tissues as well as larger samples like insects. Conventional SEM gives a magnification ranging from 20X to 30,000X and spatial resolution of 50 to 100 nanometers.

Area of Science:

  • Bibliometrics
  • Information Retrieval
  • Scientific Literature Databases

Background:

  • Increasing availability of open access full-text research articles necessitates advanced search capabilities.
  • Current search services may not fully leverage the detailed content within articles.
  • Need for sophisticated tools to refine literature searches.

Purpose of the Study:

  • Introduce a new feature in Europe PMC for searching specific sections of full-text articles.
  • Enable users to target searches to elements like figures and reference lists.
  • Improve search precision and reduce irrelevant results.

Main Methods:

  • Development of a heuristic algorithm to identify and categorize article sections.
  • Categorization of sections into 17 pre-defined types based on headings.
  • Implementation within the Europe PMC advanced search interface.

Main Results:

  • Europe PMC is the first service offering granular literature search by article section.
  • The section-tagging algorithm achieves a high performance with an F-score of 98.02% on a curated dataset.
  • Functionality allows users to search within figures, reference lists, and other specific article parts.

Conclusions:

  • The new section search functionality is now available in Europe PMC.
  • This feature enhances the ability to conduct precise literature searches.
  • The source code for the section tagger is publicly available for reuse and development.
