Sustainable Development

15.1K
As the human population continues to grow and use resources, we must be mindful of our planet’s natural limits. Sustainable development provides a pathway to maintain and improve human life now while also ensuring that future generations will have the resources that they need. The long-term success of sustainability efforts rests on understanding the interplay between human actions and ecological systems.

Social psychologists have documented that feeling good about ourselves and maintaining positive self-esteem is a powerful motivator of human behavior (Tavris & Aronson, 2008). In the United States, members of the predominant culture typically think very highly of themselves and view themselves as good people who are above average on many desirable traits (Ehrlinger, Gilovich, & Ross, 2005). Often, our behavior, attitudes, and beliefs are affected when we experience a threat to our...

Development of the Lymphatic System01:15

Development of the Lymphatic System

2.1K
The development of lymphatic tissues and vessels in embryonic life begins around the fifth week. These structures originate from the mesoderm layer, with lymph sacs emerging from developing veins.
The first lymph sacs to form are the paired jugular lymph sacs located at the junction of the internal jugular and subclavian veins. From these sacs, lymphatic capillary plexuses extend to the thorax, upper limbs, neck, and head, eventually forming lymphatic vessels. Each jugular lymph sac maintains a...

Language Development

Children master language quickly and with relative ease, supported by both biological predisposition and reinforcement. B. F. Skinner (1957) proposed that language is learned through reinforcement, while Noam Chomsky (1965) argued that language acquisition mechanisms are biologically determined.
The critical period for language acquisition suggests that the ability to acquire language is at its peak early in life. As people age, this proficiency decreases. Language development begins very...

Development of Immunocompetence

The initiation of cell-mediated immunity can be observed as early as the third month of fetal growth, with active antibody-mediated immunity following approximately one month later.
The initial cells that migrate from the fetal thymus settle within the skin and epithelial tissues lining the mouth, digestive tract, and in females, the uterus and vagina. These cells, including skin-based dendritic cells, serve as antigen-presenting cells, playing a key role in T cell activation.
Subsequent T...

Development of the Heart01:27

Development of the Heart

2.4K
The development of the human heart, a crucial organ, commences from the mesoderm on the 18th or 19th day after fertilization. This process initiates in the cardiogenic area, a group of mesodermal cells at the embryo's head end, which evolves into elongated strands known as cardiogenic cords. These cords undergo a transformation to form hollow-centered endocardial tubes.
As the embryo undergoes lateral folding, these paired tubes approach each other, merging into a single primitive heart...

Summary
This summary is machine-generated.

Sternal ossification patterns correlate with age, with vertical fusion showing higher accuracy for age prediction than horizontal fusion. This study evaluated age prediction using sternal ossification in individuals under 30.

Area of Science:

  • Forensic Anthropology
  • Radiology
  • Human Osteology

Background:

  • Sternal ossification begins in utero and continues through puberty.
  • Ossification patterns vary significantly between individuals.

Purpose of the Study:

  • To evaluate the correlation between sternal ossification and chronological age.
  • To determine the potential of sternal ossification for age prediction.

Main Methods:

  • Retrospective review of chest CT scans (slice thickness < 3 mm) in individuals under 30 without congenital anomalies or chronic conditions.
  • Collection of data on ossification centers, horizontal, and vertical sternal fusion.
  • Statistical analysis including Spearman correlation, ROC analysis, and Kruskal-Wallis test for gender comparison.

Main Results:

  • Males showed more segmented ossification centers, particularly in the mesosternum (p < 0.05).
  • Females exhibited greater vertical fusion at each level (p < 0.05).
  • Both horizontal and vertical sternal fusion significantly correlated with age (Spearman test). Vertical fusion demonstrated higher specificity (74.7-100%) compared to horizontal fusion (43.3-79.9%).

Conclusions:

  • Sternal ossification, both horizontal and vertical fusion, significantly correlates with age.
  • Vertical fusion appears to be a more reliable indicator for age estimation due to higher sensitivity and specificity.
  • Further large-scale studies are recommended to validate these findings.
