Optimal Foraging00:48

Optimal Foraging

How animals obtain and eat their food is called foraging behavior. Foraging can include searching for plants and hunting for prey and depends on the species and environment.
Data Collection by Experiments01:13

Data Collection by Experiments

Data collection is a systematic method of obtaining, observing, measuring, and analyzing accurate information. An experimental study is a standard method of data collection that involves the manipulation of the samples by applying some form of treatment prior to data collection. It refers to manipulating one variable to determine its changes on another variable. The sample subjected to treatment is known as “experimental units.”
An example of the experimental method is a public clinical trial...
Bioavailability: Overview01:13

Bioavailability: Overview

Bioavailability refers to the proportion of an unaltered drug that, after administration, enters the systemic circulation and can be distributed to the desired action site. Factors such as gastrointestinal (GI) absorption and liver biotransformation influence the bioavailability of a drug when it is administered orally. When a drug is administered intravenously, it enters the systemic circulation directly; by definition, its bioavailability is assumed to be 100%. The bioavailability of an...
Crossover Experiments01:16

Crossover Experiments

Crossover experiments, also called the repeated-measurements design, is a study design in which all experimental units are exposed to all treatments in different periods. Crossover experiments are generally used in psychology, the pharmaceutical industry, agriculture, and medicine.
Crossover designs are performed even with smaller sample sizes since the samples can act as their controls. These are better than simple randomized trials since patients are exposed to all the treatments.
An Overview of the Endocrine System01:10

An Overview of the Endocrine System

The endocrine system, a complex network of glands, orchestrates physiological balance within the body through the production and secretion of hormones. These hormones are chemical messengers in intercellular communication, acting as conduits between the secretory cells and distant target sites. They traverse the circulatory system by being released into the extracellular fluid, and their impact is specific to cells possessing receptors for a particular hormone.
The endocrine system collaborates...
Bioequivalence: Overview01:16

Bioequivalence: Overview

Pharmaceutical equivalents, by definition, are drug products with the same active ingredient in the same quantities, encapsulated in identical dosage forms, and intended for the same administration routes. These pharmaceutical equivalents are deemed bioequivalent if the bioavailability of the active entity in the drug preparations is similar. Moreover, pharmaceutical equivalents demonstrating bioequivalence are also regarded as therapeutically equivalent. This means that when used as directed,...

Area of Science:

  • Evolutionary Biology
  • Physiology
  • Bioinformatics

Background:

  • Mammalian feeding physiology research generates diverse datasets.
  • Lack of standardized data formats hinders comparative evolutionary analyses.
  • Existing data are often fragmented and difficult to access.

Purpose of the Study:

  • To introduce the Feeding Experiments End-user Database (FEED) as a centralized resource.
  • To enable synthetic and evolutionary analyses of mammalian feeding physiology.
  • To establish standardized terminology and data organization for feeding research.

Main Methods:

  • Compilation of raw physiologic data into a uniform digital format.
  • Development of standardized terminology and controlled vocabularies.
  • Integration of extensive metadata, including experimental protocols and anatomical information.

Main Results:

  • FEED serves as a central archive and repository for mammalian feeding data.
  • Metadata include text and images, enhancing data context and usability.
  • The database facilitates novel analyses on phenotype distribution and motor pattern conservation.

Conclusions:

  • FEED is a valuable research tool for evolutionary studies of mammalian feeding.
  • The database supports investigations into the phylogenetic distribution of feeding phenotypes.
  • FEED will facilitate new research into the evolution of feeding anatomy and behavior.
