A Modified Trier Social Stress Test for Vulnerable Mexican American Adolescents
Published on: July 10, 2017
Summary
Migrants moving to Oaxaca City, Mexico, often originate from district capitals, not rural areas. Contrary to common assumptions, these migrants are quite similar to non-migrants once settled in the city.
Area of Science:
- Demography
- Urban Studies
- Sociology
Background:
- Oaxaca City is an intermediate city in southern Mexico.
- Migration patterns to intermediate cities are not well understood.
- Existing literature often assumes significant differences between migrants and non-migrants in urban settings.
Purpose of the Study:
- To examine migration to Oaxaca City.
- To identify the origins of migrants.
- To compare migrants and non-migrants in Oaxaca City.
Main Methods:
- Analysis of migration data for Oaxaca City.
- Comparison of demographic and socioeconomic characteristics of migrants and non-migrants.
Main Results:
- Migrants to Oaxaca City predominantly come from district capitals.
- Migrants originate less frequently from more rural municipalities.
- Migrants and non-migrants in Oaxaca City exhibit fewer differences than previously suggested.
Conclusions:
- Migration to intermediate cities like Oaxaca City is complex.
- The origin of migrants (district capitals vs. rural areas) is a key factor.
- The assumption of stark differences between migrants and non-migrants in intermediate cities may be inaccurate.

02:07Oogenesis
In human women, oogenesis produces one mature egg cell or ovum for every precursor cell that enters meiosis. This process differs in two unique ways from the equivalent procedure of spermatogenesis in males. First, meiotic divisions during oogenesis are asymmetric, meaning that a large oocyte (containing most of the cytoplasm) and minor polar body are produced as a result of meiosis I, and again following meiosis II. Since only oocytes will go on to form embryos if fertilized, this unequal...
01:09Cell Migration
Cell migration, the process by which cells move from one location to another, is essential for the proper development and viability of organisms throughout their life. When cells are not able to migrate properly to their ordained locations, various disorders may occur. For example, disruption in cell migration causes chronic inflammatory diseases such as arthritis.
00:53Migration
Migration is long-range, seasonal movement from one region or habitat to another. This common strategy, carried out by many different organisms around the world, is an adaptive response that typically corresponds to changes in an organism’s environment, like resource availability or climate. Migrations can involve huge groups of thousands of animals as well as single individuals traveling alone and can range from thousands of kilometers to just a few hundred meters.
01:19Cell Migration
Cell migration is a process by which the cells move from one location to another, playing an essential role in embryological development, repair and regeneration, immune response, and metastasis. Cells migrate in response to chemical or mechanical signals generated by specific organs or tissues. The overall mechanism includes three steps - polarization, protrusion, and release. Polarization involves the formation of a distinct cell front and rear, which determines the direction of movement.
01:21Chemotaxis and Direction of Cell Migration
Cells can detect chemical cues in their environment and reorganize the cytoskeleton to migrate toward them or away from them. This directional migration, called chemotaxis, is essential during embryogenesis and development, immune response, tissue repair and regeneration, and reproduction. These chemical cues can either attract or repel the cell's movement. For example, axon development is determined by a combination of chemoattractants and chemorepellents that direct the growing axon towards...
01:28Toxoplasmosis
Toxoplasmosis, a zoonotic disease caused by the protozoan Toxoplasma gondii, poses significant public health challenges globally due to its high seroprevalence and varied clinical manifestations. As an obligate intracellular parasite, T. gondii can infect all warm-blooded vertebrates, but felids are its only definitive hosts, shedding unsporulated oocysts into the environment. Humans typically acquire the infection through ingestion of tissue cysts in undercooked meat or oocysts from...
