WHAT'S THE BUZZ?


Steroid use is not necessary to be heavily concerned with muscularity and leanness, suggest researchers.

According to Timothy Baghurst, University of Arkansas, there is no difference between bodybuilders who use steroids and those who do not when it comes to characteristics associated with muscle dysmorphia.

Muscle dysmorphia is a disorder in which a person becomes obsessed with the idea that he or she is not muscular enough, usually in bodybuilding.
Daniel Kissinger, an assistant professor of counsellor education, also contributed towards the understanding of mental health elements of the study as a second author of the article.

Kissinger said: “One of the problems associated with classifying muscular dysmorphia is that, while it is receiving increasing attention in the mental health literature, muscle dysmorphia is not recognised as a distinct mental illness.”


Targeted therapy raises hope for AML patients
A piece of research has shown that it is possible to eliminate stem cells related to human acute myeloid leukemia (AML), a notoriously treatment-resistant blood cancer, using a new targeted therapy.

Richard Lock, Children’s Cancer Institute Australia, has revealed that the new therapeutic approach has been found to selectively attack human cancer cells grown in the lab as well as in animal models of leukaemia.

AML is a cancer of the white blood cells that has an extremely poor prognosis and does not respond well to conventional chemotherapy.

“The cellular and molecular basis for this dismal picture is unclear. However, previous research has suggested that leukaemia stem cells (LSCs) may lie at the heart of post-treatment relapse and chemoresistance,” says Lock.

LSCs are cells that can initiate AML and are critical for its long-term growth.


Decision-making part alsodeciphers phonetic sounds
A collaborative team of researchers from Brown University and the University of Cincinnati have found that a front portion of the brain, which handles decision-making, also helps decipher different phonetic sounds.

The researchers have revealed that this section of the brain is called the left inferior frontal sulcus.

They say that this section treats different pronunciations of the same speech sound-such as a ‘d’ sound-the same way.
The researchers say that in determining this, they have solved a mystery.
MRI studies showed that test subjects reacted to different sounds — ta and da, for example — but appeared to recognise the same sound even when pronounced with slight variations. These five sounds are the same, but the fifth (right) has a slightly different pronunciation.

“No two pronunciations of the same speech sound are exactly alike. Listeners have to figure out whether these two different pronunciations are the same speech sound such as a ‘d’ or two different sounds such as a ‘d’ sound and a ‘t’ sound, said Emily Myers, Brown University.

Disparities in indigenous people tied to cultural loss
The health disparities prevalent in indigenous people around the world are closely tied to cultural loss including, loss of language, globalisation and removal from the land.
Dr Malcolm King, lead author of the paper, says that indigenous well-being is distinct, and includes physical, emotional, mental and spiritual health.

There has to be a balance between the person, his/her family, community, and environment.

“Wellbeing for aboriginal peoples is more than physical health or absence of disease, it’s about ‘being alive well’ or ‘mno bmaadis’ as they say in the Anishinabek language,” said King.
