Nature and Nurture01:10

Nature and Nurture

22.2K
Many human characteristics, like height, are shaped by both nature—in other words, by our genes—and by nurture, or our environment. For example, chronic stress during childhood inhibits the production of growth hormones and consequently reduces bone growth and height. Scientists estimate that 70-90% of variation in height is due to genetic differences among individuals, and 10-30% of variation in height is due to differences in the environments that individuals experience,...

Population Growth00:57

Population Growth

27.8K
Population size is dynamic, increasing with birth rates and immigration, and decreasing with death rates and emigration. In ideal conditions with unlimited resources, populations can increase exponentially, which plots as a J-shaped growth rate curve of population size against time. This type of curve is characteristic of newly-introduced invasive species, or populations that have suffered catastrophic declines and are rebounding.

Microbial Growth Measurement: Indirect Methods

Estimating microbial growth is essential for understanding population dynamics and environmental adaptations. Indirect methods provide valuable insights by measuring parameters such as turbidity, metabolic activity, and biomass, enabling efficient and reproducible assessments.During exponential growth, microbial cells scatter light proportionally to their biomass, a principle used in turbidity measurements. About one million cells per milliliter produce detectable scattering, which a...

Variation: Normal Distribution, Range, and Standard Deviation

In the field of psychology, there are several ways to organize measurements of a trait, feature, or characteristic (i.e., variables). Qualitative data, such as ethnicity, can be tabulated into a frequency count to provide information about the proportion, as well as the variety of groups in a sample or population. On the other hand, researchers can perform a wider set of calculations on quantitative data. The mean, mode, and median, for instance, are central tendency measures to identify a...

Direct methods for measuring microbial populations in a culture are essential tools in microbiology, providing quantitative data for various applications. Among these, microscopic counts, plate counts, and serial dilution are widely used techniques, each with unique principles and applications.Microscopic CountsMicroscopic counting involves the use of a Petroff-Hausser chamber, a specialized microscope slide with a grid and defined depth.

Oxygen Requirements and Growth Patterns

1.1K
Microorganisms exhibit diverse oxygen requirements and growth patterns driven by their metabolic strategies and environmental adaptations. Oxygen, while essential for many organisms, can also be toxic under certain conditions, shaping how microorganisms grow and survive.Oxygen Requirements of MicroorganismsMicroorganisms are classified based on their ability to use or tolerate oxygen:● Obligate aerobes like Mycobacterium tuberculosis need oxygen for energy production, as it serves as the...

Area of Science:

  • Pediatric Growth Monitoring
  • Public Health Surveillance
  • Comparative Growth Analysis

Background:

  • Growth charts are essential tools for monitoring child development against population averages.
  • Accurate growth assessment is critical for identifying potential health issues in early childhood.

Purpose of the Study:

  • To evaluate how international growth charts (INTERGROWTH-21st and WHO Child Growth) affect growth metrics in children under five when compared to national charts.
  • To understand the implications of using different growth chart standards on the classification of pediatric growth parameters.

Main Methods:

  • A systematic literature search was conducted across major databases (CINAHL, EMBASE, MEDLINE, Scopus, Web of Science).
  • Studies published between 2007-2023 comparing national charts with INTERGROWTH-21st or WHO Child Growth charts were included.
  • Growth metrics like z-scores and centiles were analyzed to compare prevalence rates of SGA, LGA, stunting, wasting, underweight, overweight, and obesity.

    • Main Results:

    • Local reference charts often reported higher z-scores/centiles for weight, length, and head circumference compared to WHO Child Growth standards.
    • Seven out of 11 studies found higher rates of small-for-gestational age (SGA) using local references versus international standards.
    • Four out of five studies indicated lower rates of large-for-gestational age (LGA) when using local references compared to INTERGROWTH-21st standards.

    Conclusions:

    • Significant discrepancies exist between national and international growth assessment standards.
    • These differences have critical implications for accurately identifying infants and children at risk due to growth deviations.
    • The choice of growth chart significantly influences clinical decisions and public health interventions related to child growth.
