Boy or girl? Australians think we shouldn't choose

2010-12-23
(Press-News.org) Most Australians do not approve of IVF or abortion for sex-selection purposes, and most do not think a hypothetical blue or pink pill to select the sex of a child should be legal, a new study has found.

The study, led by Dr Rebecca Kippen from the School of Population Health at the University of Melbourne, analysed responses from more than 2,500 people participating in the Australian Survey of Social Attitudes, combined with a series of in-depth parental interviews.

The survey found that 69 per cent of respondents disapproved the use of IVF for sex selection, with the disapproval rate increasing to 80 per cent for sex-selective abortions. The legalisation of hypothetical blue and pink pills for sex selection was supported by only 11 per cent of respondents. Dr Kippen said similar responses resulted from the in-depth interviews carried out with parents.

"Opposition to these technologies was grounded in three major concerns: the potential for distorted sex ratios; that sex selection can be an expression of gender bias; and a concern about 'designer infants' being created, when parents should be happy with a healthy baby," she said.

The findings, published online in Fertility and Sterility this month, and co-authored by Dr Ann Evans and Dr Edith Gray from the Australian Demographic and Social Research Institute at the Australian National University, contrast with previous behavioural and attitudinal research that shows Australian parents want a balanced family, that is, a family with at least one son and one daughter.

The study is particularly timely given that the National Health and Medical Research Council (NHMRC) is due to review the ban on sex selection in 2011, and has called for community discussion of issues surrounding sex selection.

The ban began in 2004, with the introduction of the NHMRC's Ethical Guidelines on the Use of Assisted Reproductive Technology in Clinical Practice and Research. These guidelines—which have the force of law—state that ''sex selection (by whatever means) must not be undertaken except to reduce the risk of transmission of a serious genetic condition''.

Cornstarch might have ended the Gulf spill agony sooner

2010-12-23
On May 25th, 2010, the online arm of Upstream, a newspaper for the international oil and gas industry, reported that British Petroleum had started top-kill procedures on the Macondo well in the Gulf of Mexico. "The company said that the operation, which will pump heavy mud down the wellbore in an attempt to gain control of the oil flow and ultimately kill the well, began at 1 pm CST," Upstream reported. The article continued: "Earlier BP Chief Tony Hayward gave the top-kill procedure a 60 percent to 70 percent chance of success." Physicists watching the situation ...

Eating less healthy fish may contribute to America's stroke belt

2010-12-23
ST. PAUL, Minn. –People living in the "stroke belt" states eat more fried fish than people living in the rest of the country, which may contribute to the high rate of death from stroke in those states, according to a study published in the December 22, 2010, online issue of Neurology®, the medical journal of the American Academy of Neurology. Studies have shown that the omega-3 fatty acids in fish, especially fatty fish, may reduce the risk of stroke. Research has shown that frying fish leads to the loss of the natural fatty acids. The study also found that African-Americans ...

Most common adult brain cancer linked to gene deletion, Stanford doctors say

2010-12-23
STANFORD, Calif. — A study fast-tracked for online publication Dec. 22 in the New England Journal of Medicine has identified an important gene deletion in up to one of every four cases of glioblastoma, the most common adult brain cancer. This deletion contributes to tumor development, promotes resistance to therapy and considerably worsens a patient's survival prospects. The deletion of the gene, known as NFKBIA, triggers biochemical processes similar to those resulting from a better-known aberration common in glioblastomas: alteration of the epidermal growth factor receptor, ...

Tau disrupts neural communication prior to neurodegeneration

2010-12-23
A new study is unraveling the earliest events associated with neurodegenerative diseases characterized by abnormal accumulation of tau protein. The research, published by Cell Press in the December 22 issue of the journal Neuron, reveals how tau disrupts neuronal communication at synapses and may help to guide development of therapeutic strategies that precede irreversible neuronal degeneration. Tau normally contributes to the supportive framework of proteins in the cell. It is well established that abnormal tau sometimes clumps into neuron-damaging filamentous deposits ...

Arsenic agent shuts down 2 hard-to-treat cancers in animal experiments

2010-12-23
Washington, DC – Researchers at the Georgetown Lombardi Comprehensive Cancer Center, a part of Georgetown University Medical Center, have found that an arsenic-based agent already FDA-approved for a type of leukemia may be helpful in another hard-to-treat cancer, Ewing's Sarcoma (ES). The research, based on animal studies, also suggests the drug might be beneficial in treating medulloblastoma, a highly malignant pediatric brain cancer. In the December 22 issue of the Journal of Clinical Investigation, the investigators describe how years of research has uncovered a common ...

Many cancer cells found to have an 'eat me' signal in Stanford study

2010-12-23
STANFORD, Calif. — Researchers at the Stanford University School of Medicine have discovered that many cancer cells carry the seeds of their own destruction — a protein on the cell surface that signals circulating immune cells to engulf and digest them. On cancer cells, this "eat me" signal is counteracted by a separate "don't eat me" signal that was described in an earlier study. The two discoveries may lead to better cancer therapies, and also solve a mystery about why a previously reported cancer therapy is not more toxic. In the study to be published Dec. 22 in Science ...

What sex are you?

2010-12-23
Sex in mammals is genetically determined. In humans, females have two X chromosomes, while males have one X and one Y chromosome. However, some individuals are born with male genitalia despite having two X chromosomes, a condition known as XX male sex reversal. A team of researchers, led by Paul Thomas, University of Adelaide, Australia, has now determined that overexpression of the Sox3 gene in mice causes frequent XX male sex reversal. The clinical relevance of this was highlighted by the discovery of genomic rearrangements in the regulatory region of the human SOX3 gene ...

KISSing a theory goodbye in the link between puberty and nutrition status

2010-12-23
The timing of the onset of puberty is linked to levels of nutrition: later onset is associated with malnutrition, while earlier onset is linked to childhood obesity. A team of researchers, led by Carol Elias, at the University of Texas Southwestern Medical Center, Dallas, has now generated data in mice that run counter to current thinking about the molecular pathway by which nutrition status affects the onset of puberty. Further, the team defines a new regulatory pathway for the process, which, if confirmed in humans, could potentially lead to new approaches to treating ...

Picking a poison for brain tumors: Arsenic

2010-12-23
Arsenic is usually thought of as a poison. Despite this, it has been used in medicine for over 2000 years, and the arsenic compound arsenic trioxide (ATO) is FDA approved for the treatment of acute promyelocytic leukemia. Now, a team of researchers, led by Aykut Üren, at Georgetown University Medical Center, Washington, has generated data using human cancer cell lines that suggest that ATO might also be of benefit to individuals with certain brain tumors or connective tissue tumors. Certain cancers, in particular brain tumors known as medulloblastomas and connective tissue ...

NIH-led study identifies genetic variant that can lead to severe impulsivity

2010-12-23
A multinational research team led by scientists at the National Institutes of Health has found that a genetic variant of a brain receptor molecule may contribute to violently impulsive behavior when people who carry it are under the influence of alcohol. A report of the findings, which include human genetic analyses and gene knockout studies in animals, appears in the Dec. 23 issue of Nature. "Impulsivity, or action without foresight, is a factor in many pathological behaviors including suicide, aggression, and addiction," explains senior author David Goldman, M.D., ...
