Back regions of the brain, which control vision, grow significantly faster than prefrontal region in newborns

The regions of the brain that control vision and other sensory information grow dramatically in the first few months following birth, while the area that controls abstract thought experiences very little growth during the same period, University of North Carolina at Chapel Hill researchers have found.

Damage to muscle during vaginal deliveries connected with pelvic organ prolapse

An increase among women electing to have caesarean sections in recent years has been due in large part to a concern that giving birth vaginally will lead to a fallen bladder and uterus in later life, and the issue has been hotly debated in the medical community.

One in four normal births cause brain hemorrhages in babies

Researchers in the United States have found that many babies who were delivered vaginally, experience bleeding in and around the brain shortly after birth.

Giving birth to a child naturally increases risk of hemorrhage in newborns

The first researchers to use magnetic resonance imaging (MRI) to study the brains of a large group of babies soon after birth found a small amount of bleeding in and around the brains of one in four babies who were delivered vaginally.

Second-generation dendrimer disintegrates upon command

Dendrimers, highly branched, spherical polymers, have demonstrated their utility as drug and imaging agent delivery vehicles for use in detecting and treating cancer, with several dendrimer-based agents nearing human clinical trials.

Design of gold nanoparticles for magnetic resonance imaging

Molecular complexes containing the element gadolinium are proven agents for increasing the diagnostic utility of magnetic resonance imaging (MRI), but their use in detecting small tumors is limited by the relatively weak signal these agents produce.

More than 1 million fewer U.S. women received mammograms since 2000

The percentage of U.S. women ages 40 and older who reported receiving a mammogram declined from 76.4% in 2000 to 74.6% in 2005, according to a report published in the Jan. 26 edition of CDC's Morbidity and Mortality Weekly Report, the Washington Post reports.

Link between MRI contrast agent and nephrogenic systemic fibrosis

New research has shown a possible association between a popular magnetic resonance imaging (MRI) contrast agent and the incidence of a rare disease called nephrogenic systemic fibrosis (NSF) in patients with kidney disease, according to an editorial appearing in the March issue of Radiology.

Magnetic resonance imaging better than computed tomography for the detection of acute stroke

Magnetic resonance imaging (MRI) is better than the more commonly used computed tomography (CT) for the detection of acute stroke, according to an Article in this week's issue of The Lancet.

Artificially engineered magnetic nanoparticles for ultra-sensitive molecular imaging

Iron oxide nanoparticles have shown promise as agents for detecting tumors using magnetic resonance imaging (MRI), but such efforts have been limited by the relatively weak magnetic signal generated by these nanoparticles.

Dendrimer-based targeted delivery of an apoptotic sensor in cancer cells

Taking a critical step toward the development of a multifunctional nanoscale anticancer agent that can detect cancer, treat it, and then report on the success or failure of that treatment, investigators at the University of Michigan have developed a nanoscale sensor of cell death.
