What is Conservation Biology?

What is Conservation Biology?

Conservation biology is a scientific field that focuses on the preservation of biodiversity in order to protect ecosystems while meeting the needs of the human population. Humans require properly functioning ecosystems to maintain our supply of natural resources, including food, medicines, and building materials.

Conservation of Small Populations

Conservation of Small Populations

Small population sizes put a species at extreme risk of extinction due to a lack of variation, and a consequent decrease in adaptability. This weakens the chances of survival under pressures such as climate change, competition from other species, or new diseases. Large populations are more likely to survive pressures such as these, as such populations are more likely to harbor individuals that have genetic variants that are adaptive under new stresses. Small populations are much less...

Conserved Binding Sites

Conserved Binding Sites

Many proteins’ biological role depends on their interactions with their ligands, small molecules that bind to specific locations on the protein known as ligand-binding sites. Ligand-binding sites are often conserved among homologous proteins as these sites are critical for protein function.
Binding sites are often located in large pockets, and if their location on a protein’s surface is unknown, it can be predicted using various approaches. The energetic method computationally...

Conservation of Protein Domains Over Different Proteins

Conservation of Protein Domains Over Different Proteins

Protein domains are small structurally independent units that are part of a single amino acid chain. Although these domains are often structurally independent, they may rely on synergistic effects to perform their functions as part of a larger protein. Protein domains may be conserved within the same organism, as well as across different organisms.
A limited set of protein domains often duplicate and recombine during evolution. These domains can be organized in different combinations to...

Non-conservative Forces

Non-conservative Forces

Non-conservative forces are dissipative forces such as friction or air resistance. These forces take energy away from a system as it progresses. Unlike conservative forces, non-conservative forces do not have potential energy associated with them. This is because the energy is lost to the system and cannot be turned into useful work later.
Also unlike their conservative counterparts, they are path-dependent; where the object starts and stops does matter. For example, a grinding wheel applies a...

Conservation of Energy

Conservation of Energy

The terms 'conserved quantity' and 'conservation law' have specific scientific meanings in physics, which differ from the meanings associated with their everyday use. For example, in everyday usage, water could be conserved by not using it, by using less of it, or by re-using it. However, in scientific terms, a conserved quantity of a system stays constant, changes by a definite amount that is transferred to other systems, and is converted into other forms of that...

Area of Science:

Neurosurgery
Trauma Surgery

Background:

Decompressive craniectomy reduces mortality in intracranial hypertension.
Bone flaps are typically stored in abdominal tissue or bone banks.
Alternative bone flap preservation methods are explored.

Purpose of the Study:

To evaluate subgaleal bone flap preservation in the contralateral scalp.
To assess the safety and efficacy of this novel preservation technique.

Main Methods:

Multicenter retrospective study (2014-2016) of 23 severe traumatic brain injury patients.
Bone flaps preserved in subcutaneous scalp tissue.
Analysis of surgical site infection, bone resorption, and patient discomfort.

Main Results:

No surgical wound infections or bone resorption observed over 18 months.
No patient discomfort reported with scalp preservation.
Five patients died from systemic complications unrelated to bone flap preservation.

Conclusions:

Subgaleal bone flap preservation is a satisfactory alternative.
This technique is suitable for routine use in decompressive craniectomy patients.
