How does proteins work?

Proteins are complex molecules made up of amino acids that play many critical roles in the body, including providing structure to cells and tissues, facilitating chemical reactions, and serving as signaling molecules. Proteins work through their unique three-dimensional shapes, which allow them to interact with other molecules in specific ways to carry out their functions. Additionally, proteins can be modified through processes like phosphorylation to regulate their activity.

What is the Roman name for the greek god Athena?

The Roman name for the Greek god Athena is Minerva.

Are all mutations dominant?

No, not all mutations are dominant. Mutations can be dominant, recessive, or have incomplete dominance depending on how they affect the resulting trait and how they interact with other genes in the organism. Dominant mutations are expressed even if there is only one copy of the mutated gene, while recessive mutations require two copies to be expressed.

Can asthmatics donate organs?

In general, individuals with well-controlled asthma may be eligible to donate organs. However, each case is evaluated individually based on factors such as the severity of the asthma, organ function, and overall health of the donor. It is important to consult with healthcare providers and transplant professionals for guidance on organ donation eligibility.

How does Perfume effect ozone and health?

Ozone only attacks one other molecule faster that the double carbon bonds of most aromatics. So do most organic systems use them, and consume them. Perfumes are not currently used in large enough quantities to present a challenge to the ozone layer. They do act as VOCs, and could potentially serve as one of the contaminants necessary to make ozone... before they were consumed by that ozone. After that, unlikely they'd continue to make more ozone. Someone want to add health effects of perfume?...

Why is it that in very cold climates indoor relative humidity can be low while the outside relative humidity can be high?

Because it's about relative humidity, not absolutehumidity. Air can carry a certain amount of moisture dependent on which temperature it is, with warmer air being able to carry more before condensation occurs. If you have two volumes of air, both containing the same amount of water, then the warm volume will be a lower relative humidity than the cold volume.

Are ozone air filtration systems bad for your health?

They can be. They are bad if you are in the space they are adding ozone to. They should have timers, and be turned off a few hours before you (or your pets) return home. They are especially bad if you have asthma. But they are good for destroying odors.

What happen to the plastic bags or after people throw it away?

When people throw away plastic bags, they often end up in landfills where they can take hundreds of years to decompose. Some may also end up in the environment, harming wildlife and polluting ecosystems. Recycling plastic bags can help reduce their environmental impact.

What is theophylline?

What is in inhalers?

Inhalers typically contain a medication (such as bronchodilators or corticosteroids) in a liquid, powder, or aerosol form. The medication is designed to be delivered directly to the lungs through inhalation to treat respiratory conditions like asthma or COPD. Some inhalers may also contain propellants to help deliver the medication effectively.

What is the pathogen causes Asthma?

Bacterial infections, chronic viral infections, or colonization with pathogenic bacteria may cause non-atopic asthma. Asthma is typically caused by allergens but pathogens including virus infections and influenza viruses may also be cause of asthma.

Is keeping the heat on at night bad for your health?

Keeping the heat on at night is generally not bad for your health, as long as the room is well-ventilated and the temperature is not too high. However, excessively high temperatures or poor ventilation can lead to issues like dehydration, dry skin, or respiratory problems. It's important to find a comfortable temperature that allows for restful sleep without overheating.

What is dominant negative mutation?

A negative mutation is one which is harmful to the organism. The result of a negative mutation is a non-sense protein. Examples of negative mutations include:

  • a frame shift mutation - codons are read wrong
  • an insertion mutation - insertion of a sequence of extra nucleotides
  • a deletion mutation - deletion of a chain of nucleotides
  • a non-sense mutation - results in the creation of a non-sense protein
  • a transition mutation - exchange of purines to pyrimidines thus changing the nucleotide sequence and resulting in a mutation.

How might smoking affect tidal volume?

In a person with emphysema, there is a significant loss of intrinsic elastic recoil in the lung tissue. This loss of elastic recoil occurs as the disease destroys the walls of the alveoli. Airway resistance is also increased as the lung tissue in general becomes more flimsy and exerts less mechanical tethering on the surrounding airways. Thus the lung becomes overly compliant and expands easily. Conversely, a great effort is required to exhale as the lungs can no longer passively recoil and deflate. A noticeable and exhausting muscular effort is required for each exhalation. Thus a person with emphysema exhales slowly. Thus decreasing the tidal volume.

When was asthma first discovered?

While asthma-like symptoms were described as far back as ancient Egypt around 1500 B.C., asthma was first defined as a term around 400 B.C. by the Hippocratic authors of Con, ancient Greece. Some authors give full credit for defining the term asthma for the medical community to Hippocrates, although most experts now believe there were many authors. He did not define asthma the way we do today. Instead, he defined it as a symptoms of shortness of breath. Gradually, since that time, asthma was slowly morphed into what it is today, with all the other ailments that cause shortness of breath (kidneys, heart, common cold, croup, etc.) being extricated from the rubric term asthma to become disease entities of their own. Asthma was proven to be a disease of spasms of the lungs by Charles J. B. Williams in 1840, with various physicians over the next 100 years confirming this theory. It wasn't until the 1990s that asthma was found to be a disease of chronic inflammation of the air passages.

If you use your inhaler when you dont need it is it bad?

Using an inhaler when you don't need it can lead to overuse of the medication, which can cause potential side effects like increased heart rate, tremors, and an increased risk of developing a tolerance to the medication. It's important to use your inhaler only as prescribed by your healthcare provider to avoid these risks.
