Relationship Formation

46.3K
What do you think is the single most influential factor in determining with whom you become friends and whom you form romantic relationships? You might be surprised to learn that the answer is simple: the people with whom you have the most contact. This most important factor is proximity. You are more likely to be friends with people you have regular contact with. For example, there are decades of research that shows that you are more likely to become friends with people who live in your dorm,...

Design of Columns under a Centric Load

579
The design of columns under centric load is a fundamental aspect of structural engineering and is critical for ensuring the stability and integrity of structures. Euler's and Secant's formulas are central to understanding and calculating the critical load and deformation behaviors of columns, providing a basis for safe and effective structural design.
Euler's formula is applicable under the assumption that the column is a perfect, straight, homogenous prism, and it is operating...

Ending Relationships

207
The dissolution of intimate relationships presents complex emotional and psychological challenges, particularly when emotional bonds are strong, the relationship is long-standing, and perceived alternatives are limited. This distress often intensifies in romantic breakups, where the initiator may experience greater turmoil than the rejected partner. Contributing factors include residual attachment, guilt over causing pain, and uncertainty about how to manage the situation. The stress is further...

Lipid Digestion01:06

Lipid Digestion

100.0K
Lipids are large molecules that are generally not water-soluble. Since most of the digestive enzymes in the human body are water-based, there are specific steps the body must take to break down lipids and make them available for use.

Structure of Lipids03:38

Structure of Lipids

99.5K
Lipids include a diverse group of compounds that are largely nonpolar in nature. This is because they are hydrocarbons that include mostly nonpolar carbon-carbon or carbon-hydrogen bonds. Non-polar molecules are hydrophobic (“water fearing”), or insoluble in water. Lipids perform many different functions in a cell. Cells store energy for long-term use in the form of fats. Lipids also provide insulation from the environment for plants and animals. For example, they help keep aquatic...

Area of Science:

  • Immunology
  • Microbiology
  • Metabolic research

Background:

  • Macrophages are key immune cells defending against pathogens like bacteria.
  • Bacteria can exploit macrophages, thriving intracellularly and manipulating host metabolism.
  • Lipid metabolism is crucial for macrophage function and immune responses during infection.

Purpose of the Study:

  • To review the roles of lipids in host-pathogen interactions.
  • To discuss methodologies for studying lipid metabolism in infection.
  • To highlight lipids as potential therapeutic targets.

Main Methods:

  • Systems-scale analyses (genomics, transcriptomics, proteomics, metabolomics).
  • Classical biological approaches.
  • Review of emerging research and methodologies.

Main Results:

  • Macrophages undergo significant lipid remodeling upon activation and infection.
  • Pathogens evolve strategies to manipulate host lipid metabolism for their benefit.
  • Host lipid metabolism directly influences infection susceptibility and outcomes.

Conclusions:

  • Lipids play a central role in the host-pathogen relationship.
  • Targeting lipid metabolism presents a promising avenue for novel anti-infective therapies.
  • Existing lipid-modulating drugs may be repurposed for infectious diseases.
