A recently study [http://www.lifenews.com/nat6463.html] published in the American Journal of Public Health [online 17 June 2010] found that 14 percent of women who had abortions reported having experienced physical or sexual abuse at least once in the past year.
The survey of 986 women found that 10 percent reported physical abuse and 3 percent reported sexual abuse, with 74 percent of women reporting they were abused by a current partner and 24 percent reporting abuse by a previous partner (some women reported abuse by both current and former partners).
While the study only asked about the year prior to the abortion, many post- abortion counselors have found that many women who have had abortions report a history of sexual abuse, perhaps in their childhood. Most discussion about abortion and sexual abuse concerns what happens if a woman or girl becomes pregnant as a result of rape or incest.
The book Forbidden Grief: The Unspoken Pain of Abortion (http://www.theunchoice.com/forbiddengrief.htm) explores the further connection between abortion and a history of sexual abuse that may have occurred before the pregnancy took place.
Audrey Saftlas, Universiy of Iowa professor of epidemiology and lead author of the study, commented: "Women seeking termination of pregnancy comprise a particularly high-risk group for physical or sexual assault. In our study, almost 14 percent of women receiving an abortion reported at least one incident of physical or sexual abuse in the past year."
"These findings strongly support the need for clinic-based screening with interventions. These high-risk women need resources, referrals and support to help them and their families reduce the violence in their lives," Saftlas added.

HAMLET: Substance Found in Breast Milk Kills 40 Types of Cancer Cells (POJ, 2/10) |

HAMLET: Substance Found
in Breast Milk Kills 40 Types of Cancer Cells
Swedish researchers have discovered that a substance found in human
breast milk has the ability to kill cancer cells, according to a study
published in the PLoS One Journal.
The substance known as HAMLET (Human Alpha-lactalbumin Made
Lethal to Tumor cells), was discovered years ago, but has just recently
been tested on humans.
In the trial conducted at Lund University in Sweden, patients suffering
from bladder cancer were treated with HAMLET. After each treatment, the
patients excreted dead cancer cells in their urine, healthy cells
remaining intact.
Previous laboratory experiments showed that HAMLET has the ability to
kill 40 different types of cancer cells, but this was the first test
conducted on humans. The next step will be to test the substance on skin
cancer and brain tumors.
The trial breakthrough increases the hopes that HAMLET will be developed
into a cancer treatment medication in the future. [April 20, 2010,

with Lipid Membranes and Perturbs Their Structure and Integrity"

Abstract
Background
Cell membrane interactions rely on lipid bilayer constituents and
molecules inserted within the membrane, including specific receptors.
HAMLET (human α-lactalbumin made lethal to tumor cells) is a tumoricidal
complex of partially unfolded α-lactalbumin (HLA) and oleic acid that
is internalized by tumor cells, suggesting that interactions with the
phospholipid bilayer and/or specific receptors may be essential for the
tumoricidal effect. This study examined whether HAMLET interacts with
artificial membranes and alters membrane structure.
Methodology/Principal Findings
We show by surface plasmon resonance that HAMLET binds with high
affinity to surface adherent, unilamellar vesicles of lipids with
varying acyl chain composition and net charge. Fluorescence imaging
revealed that HAMLET accumulates in membranes of vesicles and perturbs
their structure, resulting in increased membrane fluidity. Furthermore,
HAMLET disrupted membrane integrity at neutral pH and physiological
conditions, as shown by fluorophore leakage experiments. These effects
did not occur with either native HLA or a constitutively unfolded
Cys-Ala HLA mutant (rHLAall-Ala). HAMLET also bound to plasma membrane
vesicles formed from intact tumor cells, with accumulation in certain
membrane areas, but the complex was not internalized by these vesicles
or by the synthetic membrane vesicles.
Conclusions/Significance
The results illustrate the difference in membrane affinity between the
fatty acid bound and fatty acid free forms of partially unfolded HLA and
suggest that HAMLET engages membranes by a mechanism requiring both the
protein and the fatty acid. Furthermore, HAMLET binding alters the
morphology of the membrane and compromises its integrity, suggesting
that membrane perturbation could be an initial step in inducing cell
death.
