Stem cells from amniotic fluid no substitute for embryonic cells

The Genetics Policy Institute (GPI) applauds the discovery of apparently versatile stem cells in amniotic fluid as a positive development, but cautions that the research does not eliminate the need for embryonic stem cell research.

Red tide toxins may trigger respiratory symptoms

The ecological phenomenon, known as Florida red tide, can be harmful for people with asthma. Florida red tides, an annual event in areas along the Gulf of Mexico, are blooms of the ocean organism, Karenia brevis (K brevis), that are concentrated along shorelines and produce highly potent aerosolized toxins.

New alarm system protects nerves during surgery

An alarm tone warns the surgeon that the position of his scalpel is dangerously close to the nerve leading to the patient's vocal cords - the beep tone signals excessive pressure on the nerve.

New carbon-fiber-reinforced plastic puncture needle

Sometimes it begins with a slight pulling sensation in the back, while at other times it can put a person completely out of action from one minute to the next: These are the symptoms of a slipped disk. An operation is not always necessary, as there are effective alternatives to surgery.

Young single men are more likely to bank sperm before testicular cancer treatment

A quarter of men with testicular cancer banked their sperm before treatment, but only six per cent of those actually used the sperm to father a child, according to a study published in the January issue of the UK-based urology journal BJU International.

Abnormal hair development and apparent follicular transformation to mammary gland in the absence of Hedgehog signaling

One single molecule determines how stem cells in the hair follicle develop. A study at the Sahlgrenska Academy at Göteborg University in Sweden has shown that cells that should give rise to hair can instead give rise to mammary gland cells in mice who lack this molecule.

Interleukin-13 receptor-targeted nanovesicles are a potential therapy for glioblastoma multiforme

Glioblastoma multiforme is among the most aggressive and difficult cancers to treat. Now, researchers at Penn State University have shown that a lipid-based nanoparticle, designed to bind to a specific receptor found on malignant brain cells but not healthy ones, improves the potency of a common anticancer drug and slows significantly the growth of glioblastoma in mice.

A fully integrated microfluidic genetic analysis system with sample-in-answer-out capability

In an accomplishment that represents a significant step toward an era of rapid, inexpensive, bedside testing for cancer, researchers at the University of Virginia have developed a microfluidic device that can process human blood samples and yield diagnostic results within an hour.

Optical and magnetic resonance imaging of cell death and platelet activation using annexin A5-functionalized quantum dots

By combining a quantum dot with a novel carrier of the magnetic resonance imaging (MRI) agent gadolinium, a team of investigators at the University of Maastricht, in The Netherlands, has developed a nanoparticle that can spot apoptosis, or programmed cell death, using both MRI and fluorescence imaging.

Dendrimer-encapsulated camptothecins

With an eye toward developing a delivery vehicle for anticancer agents that are poorly soluble in water, a research team at Boston University and the Research Triangle Institute (RTI) has developed a biocompatible dendrimer that wraps itself around water-insoluble drugs.

In vivo biodistribution and highly efficient tumour targeting of carbon nanotubes in mice

In the first experiment of its kind, investigators at the Center for Cancer Nanotechnology Excellence Focused on Therapy Response (CCNE-TR), based at Stanford University, have shown that single-walled carbon nanotubes (SWCNTs) wrapped in poly(ethylene glycol), or PEG, can successfully target tumors in living animals.
