Multi-million pound UK Biobank underway

.... Further information is available on request (and via a web site www.ukbiobank.ac.uk), with a freephone number that volunteers and GPs can ring to raise any queries with a study team member. No one is pressured into taking part, and participants can withdraw at any time if they change their minds. The f...

Avian influenza virus in mammals spreads beyond the site of infection to other organ systems

...n hosts, Rimmelzwaan et al. examined cats infected via the respiratory tract, via the digestive tract (by feeding on infected chicks), or by close contact with respiratory-infected c...

Flu not the only germ threat this time of year

... the common cold, spreads mainly as large droplets via surfaces ?doorknobs, faucets, dishtowels, and hand-to-hand contact, for instance. "Unlike the flu, RSV is more often spread directly by secretions," said William Hall, M.D., a geriatrician and pulmonary specialist at the University of Rochester Medi...

Scientists discover basic defect in cystic fibrosis airway glands

...explanation is that the glands still secrete fluid via non-CFTR pathways, but the fluid is reabsorbed by other channels. In fact, it has been proposed that one of CFTR's functions is to inhibit the activity of a channel called the epithelial Na+ channel (ENaC). Nam Soo Joo and colleagues at Stanford Un...

How nerve cells stay in shape

Nerve cells store and transmit information via special contact sites called synapses. Synapses al...Nerve cells receive signals from other nerve cells via dendrites, which branch out like the branches of a tree. The cell-body receives incoming information...

'Nano-keys' bind cell receptors and trigger allergic reactions

...hat these nano-keys could interfere with responses via the membrane interactions, rather than just targeting proteins to block responses. This could lead to designing ligands (molecules that bind to receptors) that trigger a desired response or inhibit an allergic reaction and preventing the release of h...

Cheaper and simpler keyhole surgery

...nd-eye coordination, as the surgeon has to operate via a 2D image on a monitor. Moreover, the video camera has to be operated by an assistant and the work must be done using long and rigid instruments that provide little freedom of movement. The existing robot systems that have been developed to solve th...

New University of Toronto research a 'pore' excuse for engineering

...ven lead to new methods for delivering medications via skin patches. The material, known as periodic mesoporous organosilica (PMO), is a thin film interspersed with pores just two-billionths of a metre across. The team created it by mixing an organosilica precursor (silica glass, containing organic grou...

Anthrax inhibitor counteracts toxin, may lead to new therapeutics

...." The 2001 intentional release of anthrax spores via postal mail in the United States led to increased research on possible therapeutics and vaccines to treat toxins that could be used as biological weapons. The current treatment for anthrax exposure is antibiotics, but inhalation anthrax still has a f...

Scientists discover interplay between genes and viruses in tiny ocean plankton

...ing on among the ocean's tiny plankton. It happens via ocean-dwelling viruses, scientists report this week in the journal Science. Conducted by biological oceanographers Sallie Chisholm and her colleagues at the Massachusetts Institute of Technology, the research is uncovering a new facet of evolution a...

Ebola DNA vaccine produces immune responses in all fully vaccinated volunteers in Phase 1 trial

Three cohorts tested progressively higher doses of the vaccine at 2 mg (5 subjects), 4 mg (8 subjects), or 8 mg (8 subjects ?with 6 receiving the full three doses). Each cohort included two additional subjects who ...

Rice bioengineers pioneer techniques for knee repair

... that we would be making entire articular end caps via self assembly I would have said you were crazy," said Athanasiou. "The fact that we can do this is an indication of how far the discipline of tissue engineering has progressed." Unlike cartilage, most tissues in our bodies ?including skin, blood ves...

Master genetic switch found for chronic pain

... by translating painful stimuli into nerve signals via specialized pores called "ion channels" in the neurons, as well as specialized receptors. The researchers' studies of Runx1 in these cells revealed that during embryonic development, the gene is characteristically expressed in pain-receptor cells inv...

Carnegie Mellon scientists show brain uses optimal code for sound
