Depression tied to higher risk of heart disease death

Researchers found that depressed patients are twice as likely to die within two years after their first heart disease episode compared to non-depressed patients. The study also discovered a stronger link between depression and higher risk of death in studies published before 1992.

Study examines relationship of vitamin A pathway to breast tumor progression

Researchers found that reduced CRBP-I function compromises RAR activity, leading to loss of cell differentiation and tumor progression. The study suggests that somatic CRBP-I loss may contribute to breast cancer development and highlights the need for further research into vitamin A's role in cancer prevention.

Residual tumor cells are a barrier to targeted cancer therapeutics

Researchers found that 50% of c-MYC-induced mammary cancers persisted in mouse models despite c-MYC gene blockage. Residual cancer cells quickly recovered malignant properties after treatment and eventually progressed to independent growth states.

Stem cell therapy for ailing hearts

In an animal study, stem cells from human umbilical cord blood significantly reduced the size of heart damage and restored pumping function to near normal after a heart attack. The researchers suggest that these stem cells could be a new treatment for limiting or repairing heart muscle damaged by a heart attack.

Study reveals high infection rate in teens for virus linked to cervical cancer

A recent study by Indiana University School of Medicine found that nearly all sexually active adolescent females aged 14-17 were infected with the human papillomavirus. The researchers also discovered that many of these participants had multiple HPV types, which are associated with an increased risk for cervical cancer.

Study pinpoints protein's role in heart failure prevention

Researchers pinpoint MuRF1's role in regulating cardiac cellular molecules involved in abnormal heart enlargement. The protein degrades troponin-1, a critical component of the cardiac contractile machinery, suggesting new therapeutic avenues for treating cardiac hypertrophy.

Environmental tobacco smoke linked to reading, math, logic and reasoning declines in children

A study found that environmental tobacco smoke exposure is linked to significant declines in reading and math scores, as well as logic and reasoning skills in children. The research suggests that even low levels of exposure can have adverse effects on cognitive abilities, with an estimated 33 million US children at risk.

Women need less morphine after hysterectomies with new treatment

Researchers have developed a new treatment that significantly reduces morphine use after hysterectomies, leading to improved lung function and more consistent pain relief. The treatment combines two non-opioid drugs, gabapentin and rofecoxib, which work together to alleviate movement-related pain and promote better breathing.

Magnetic resonance imaging deconstructs brain's complex network

Researchers used MRI to study brain activity and found that tens of thousands of discrete brain regions form a network with the same features as other complex networks, such as the Internet. The brain network shares two fundamental properties: small world connectivity and in-homogeneity, allowing for efficient information transmission.

USC researchers find evidence that progesterone signaling influences ovarian cancer risk

Researchers from USC found evidence that progesterone signaling influences ovarian cancer risk, particularly two haplotypes (4-D and 4-E) that increase risk by almost 3.5-fold in women who carry them. The study's findings suggest that subtle changes in the progesterone receptor gene may decrease its efficiency, leading to ovarian cancer.
