Segregation Of Chromosomes Affected By Tissues

Biologists discover that the environment surrounding a cell plays an integral role in its ability to accurately segregate its chromosomes. New research by a group of MIT biologists reveals that this long-held assumption is incorrect.

In a paper published this week, they describe how some types of cells rely on signals from surrounding tissue in order to maintain chromosome stability and segregate accurately.  All growth and reproduction rely on a cell’s ability to replicate its chromosomes and produce accurate copies of itself. Every step of this process takes place within that cell.

The study was published online in the journal Cell. Based on this observation, scientists have studied the replication and segregation of chromosomes as a phenomenon exclusively internal to the cell. They traditionally rely on warm nutritional cultures that promote growth but bear little resemblance to the cell’s external surroundings while in its natural environment.

Common Myths About Hospice Care, Palliative Care

An extremely aggressive form of brain cancer. Like pancreatic cancer, glioblastoma has one of the lowest five-year survival rates of all major cancers. In the days leading up to McCain’s death, his family issued a statement announcing that he had chosen to “discontinue medical treatment,” which prompted a discussion about the differences in treatment intended to stop cancer growth vs. palliative care and end-of-life care. Below, we explain the differences and dispel common myths.

Variant Models Can Predict Patient Mortality In The ICU

In intensive care units, where patients come in with a wide range of health conditions, triaging relies heavily on clinical judgment. ICU staff run numerous physiological tests, such as bloodwork and checking vital signs, to determine if patients are at immediate risk of dying if not treated aggressively. By training on patients grouped by health status, the neural network can better estimate if patients will die in the hospital.

Relationship Between Heart Disease And Hearing Loss

A study showed the relationship between heart disease and hearing loss has been studied over the years. While there is not a direct causal link between heart disease and hearing loss, there is a large body of evidence suggesting a relationship between the two. 

Heart disease, also known as cardiovascular disease, occurs when blood vessels become narrowed or blocked. Cardiovascular disease can also be the result of damage to the heart’s muscle, valves, and/or rhythm. Cardiovascular disease can lead to stroke, heart attack, and chest pain. Currently, cardiovascular disease is the leading cause of death among men and women in the U.S.

Myths Surrounding The Skin Condition Persist In This Era

Psoriasis is a long-lasting noncontagious skin condition that can cause much discomfort. Because of its unpleasing appearance, psoriasis is often accompanied by stigma. A new study reveals that myths surrounding the skin condition still persist in this era of readily available information.

Characterized by reddish, scaly lesions capable of causing itching, burning sensations, or both, psoriasis affects people's quality of life to a great degree. This and many other myths and ungrounded fears persist to this day in the United States so suggest a new study published in the Journal of the American Academy of Dermatology.

Medicines For Treatment In Type 2 Diabetes And On Insulin In Type 1 And Type 2 Diabetes

The World Health Organization developed these guidelines to provide guidance on selection of medicines for treatment intensification in type 2 diabetes and on use of insulin (human or analog) in type 1 and 2 diabetes. The target audience includes clinicians, policymakers, national diabetes program managers, and medicine procurement officers.

The target population is adults with type 1 or 2 diabetes in low-resource settings in low- or high-income countries. The guidelines also apply to disadvantaged populations in high-income countries.

Astronauts Use Technology To Survive In Space

Researchers have proposed an upper limit on exoplanet gravity that would allow a trained athlete to live comfortably on a distant world. Astrobiologists often consider the potential habitability of newly-discovered exoplanets by measuring the properties of their atmospheres.  However, as the Apollo Moon missions proved, humans can use technology to survive in a distant, hostile atmosphere.
