Summary
Brazilian zebrafish (Danio rerio) research shows strong applied focus in toxicology and pharmacology, with significant national and international collaborations. However, scientific output is geographically concentrated, highlighting regional inequalities.
Area of Science:
- Bibliometric analysis of Brazilian zebrafish (Danio rerio) research.
- Focus on national scientific output, collaboration networks, and thematic trends.
Background:
- Brazil is a significant global contributor to zebrafish research.
- Lack of comprehensive analysis on Brazil's national research landscape.
Purpose of the Study:
- To systematically analyze Brazilian zebrafish research output from 2020-2025.
- To map national collaboration networks and identify thematic focuses.
Main Methods:
- Bibliometric analysis of 801 Brazilian-corresponding articles.
- Analysis of geographic distribution, collaboration patterns, and research themes.
Main Results:
- Brazilian research output (2.7% of global) concentrated in South/Southeast regions (65%).
- Robust national (34% interstate) and international (30.4%) collaborations observed.
- Dominant research themes: Toxicology (34%), Pharmacology (18.3%), Neuroscience (15%), using adult zebrafish (64%).
Conclusions:
- Brazilian zebrafish research is dynamic, collaborative, and thematically focused, particularly in applied areas.
- Persistent regional inequalities in scientific output exist.
- Establishes a baseline for understanding Brazilian science in a key model organism.

01:42Microtubule Associated Proteins (MAPs)
6.0K
Microtubule function and architecture are regulated by an array of specialized proteins called microtubule-associated proteins or MAPs. These proteins are widespread across different organisms and have conserved protein motifs, like the multi-TOG domain for tubulin binding found in the CLASP family of MAPs. Some MAPs are lineage-specific based on their conserved domains. Their functions depend upon the cytoskeletal architecture and cell type they are located within. In-plant cells, a specific...

01:29Plotting of Topographic Maps
548
Topographic maps represent the Earth's surface features using contour lines, which connect points of equal elevation to create a two-dimensional representation of three-dimensional terrain. Creating a topographic map requires a systematic approach.Begin by plotting a scaled grid and marking intersections corresponding to the survey's elevation data points. Assign elevation values at these intersections to build the base map. Next, determine contour levels using a consistent contour interval,...

01:29Coordinates and Map Projections
628
Coordinates and map projections are essential tools in accurately representing the Earth's surface for various applications, ranging from navigation to spatial analysis. The latitude and longitude coordinate system is a universally recognized framework for defining locations. Latitude specifies the distance of a point north or south of the equator, measured in degrees from 0° at the equator to 90° at the poles. Longitude indicates a location's position east or west of the prime meridian,...

03:46Qualitative Analysis
24.7K
For solutions containing mixtures of different cations, the identity of each cation can be determined by qualitative analysis. This technique involves a series of selective precipitations with different chemical reagents, each reaction producing a characteristic precipitate for a specific group of cations. Metal ions within a group are further separated by varying the pH, heating the mixture to redissolve a precipitate, or adding other reagents to form complex ions.

03:40Dimensional Analysis
65.1K
Dimensional analysis, also known as the factor label method, is a versatile approach for mathematical operations. The main principle behind this approach is: the units of quantities must be subjected to the same mathematical operations as their associated numbers. This method can be applied to computations ranging from simple unit conversions to more complex and multi-step calculations involving several different quantities and their units.
