Biodiversity and Human Values

17.1K
Human civilization relies on biodiversity in many ways. Sudden changes in species biodiversity result in environmental changes that can modify weather patterns and therefore human civilizations.

Human Genetics

1.6K
Human genetics provides a profound framework for understanding the interplay between genetic predispositions and human psychology. At the heart of this discipline lies the study of how genes influence physical traits, behaviors, and susceptibility to diseases. Each person carries a unique genetic code that subtly or significantly shapes their psychological and behavioral landscape.
The complex relationship between genetics and psychology is observable through common biological components such...

What are Cells?01:07

What are Cells?

201.2K
Cells are the smallest and basic units of life, whether it is a single cell that forms the entire organism, e.g., in a bacterium or trillions of them, e.g., in humans. No matter what organism a cell is a part of, they share specific characteristics.
Basic Characteristics of Cells
A living cell has a plasma membrane, a bilayer of lipids that separates the aqueous solution inside the cell called the cytoplasm from the outside environment.
Furthermore, a living cell possesses genetic information...

Requirements for Human Life

13.9K
The Earth and its atmosphere have provided humans with air, water, and food, but these are not the only requirements for survival. Humans also require a specific range of temperature and pressure that the Earth and its atmosphere provides.
Oxygen
Atmospheric air is only about 20 percent oxygen, but that oxygen is a key component of the chemical reactions that keep the body alive, including the reactions that produce ATP. Brain cells are susceptible to a lack of oxygen because they require a...

Role of Proteins in the Human Body

6.4K
Proteins are the building block of life. They are also  the most abundant macromolecules with as many diverse roles in the body. They are part of many structural components that provide unique shapes and structures to animal cells, tissues, and organs. In addition, they also act as biological catalysts and carry out several anabolic and catabolic reactions. Notably, some proteins are chemical messengers and regulate many critical processes, such as metabolism, growth, and development. They...

Maslow's Theory of Basic Human Needs01:28

Maslow's Theory of Basic Human Needs

3.3K
Maslow's hierarchy is described with the help of a pyramidal shape. The most fundamental needs, physiological needs, are at the bottom of the pyramid.
Physiological needs such as hunger, thirst, sex, physical comfort, and survival are at the bottom of the pyramid. These are the components that are necessary to sustain life. Once the first level of needs has been met, the second level arises.
Safety needs include stability and predictability. Protection and freedom from danger are all a part...

Area of Science:

  • Hematology
  • Stem Cell Biology
  • Transplantation Immunology

Background:

  • Hematopoietic stem cell (HSC) engraftment is vital for successful transplantation.
  • HSC homing to the bone marrow niche is a critical, yet poorly understood, step for engraftment.
  • Cellular migration in response to cytokines and chemokines is implicated in HSC homing and mobilization.

Purpose of the Study:

  • To describe a laboratory methodology for evaluating the migration of human CD34+ cells, which contain HSC.
  • To contribute to understanding the molecular mechanisms regulating HSC homing and mobilization.

Main Methods:

  • The study focuses on the methodology used in the laboratory to assess cell migration.
  • Specifically, it evaluates the migration of human CD34+ cells, a population enriched for HSC.

Main Results:

  • The described methodology provides a means to assess HSC migration.
  • This evaluation is crucial for elucidating the mechanisms of HSC homing and mobilization.

Conclusions:

  • Understanding HSC migration is essential for improving HSC transplantation outcomes.
  • The presented methods facilitate research into the complex processes of HSC homing and mobilization.
