Tryptophan deficiency may underlie quinine side effects

... mode of quinine action against the malaria parasite is still largely unclear, as is the basis for adverse reactions like nausea, headaches, and blurred vision. To address these gaps, Simon Avery and colleagues at the University of Nottingham took advantage of yeast genetics, examining the effects of ...

Tree lizard’s quick release escape system makes jumpers turn somersaults

... filmed them. As soon as the first animal took to the air, Gillis knew something was different. 'It looked weird' says Gillis, 'the animals became blurred as they jumped. I called Lauren over and said "you're not going to believe this"'. Replaying the animal's jump in slow motion, the team could see ...

Scientists discover how deadly fungus protects itself

... the body, including the brain. The resulting infection, called cryptococcosis, can cause chest pain, dry cough, abdominal swelling, headache, blurred vision, or confusion. The infection can be fatal, especially if not treated with antifungal medications. "It's a horrendous disease, and even ...

Researchers describe protease inhibitor that may aid in diabetic retinopathy treatment

... into the retina and the clear, gel-like vitreous that fills inside of the eye. Unless quickly treated, this can result in spots, floaters, flashes, blurred vision, vision loss, and even temporary blindness. In later phases of the disease, continued abnormal vessel growth and the formation of scar tissue ...

Novel technique for fluorescence tomography of tumors in living animals

... depth of a few hundred micrometers the photons are massively scattered due to interactions with cell membranes and organelles which results in blurred images. In the latest issue of the journal Proceedings of the National Academy of Sciences Prof. Ntziachristos and his team, together with ...

Men are red, women are green, Brown researcher finds

... face is ambiguous or hidden. Another study found, for example, that observers are quite sensitive to the color of faces when the facial images are blurred to the point where the face shape is almost impossible to see. ...

Climate change may boost Middle East rainfall

... more localised regional scale," says Dr Evans. "It's a bit like enlarging a digital photograph until it becomes pixellated and all sorts of detail is blurred out." "Simulating the climate of the region is a challenge for climate models, due in part to the high natural inter-annual variability, the ...

Scientists demonstrate the sharpest measurement of ice crystals in clouds

... could do in the past to measure cloud ice crystals was to try to record images of them, but for crystals below 25 microns, the images were too blurred to allow accurate determination of the crystal's shape. Researchers need to know the shape and sizes of these ice crystals because these ...

Indiana U scientists uncover potential key to better drugs to fight toxoplasmosis parasite

... immune system problems such as those undergoing chemotherapy or people with AIDS the disease can cause serious effects including lung problems, blurred vision and seizures. Also, infants born to mothers who are infected during or shortly before pregnancy are at risk for severe complications, ...

Argonne scientists develop techniques for creating molecular movies

... motions have not yet been seen directly, but scientists using the high intensity x-rays at the Advanced Photon Source have measured images that are blurred by these motions and have used them to create more accurate movies of molecular motions. Computer simulations are currently the only way to ...

Study identifies warning signs of pregnancy danger

... the condition on an outpatient basis by checking in regularly with their patients. They generally look for the symptoms of persistent headache, blurred vision and abdominal pain as signs that it could be getting worse. In the study, Black suggests also assessing for other symptoms such as perceived ...

Sleep enforces the temporal sequence in memory

... This finding shows that sleep associated consolidation of memories enforces the temporal structure of the memorized episode that otherwise might be blurred to a timeless puzzle of experiences. ...

Stanford snake venom study shows that certain cells may eliminate poison

... snakebite is horrible. The immediate pain of the bite is followed by swelling, bruising and weakness, then sweating or chills, with numbness, nausea, blurred vision and possibly convulsions before it's all over. Such misery is produced by a veritable witches' brew of toxins in snake venom. It's long ...

Researchers reverse juvenile diabetes in animal model

Scientists discover stem cell origin of neck and shoulders

... show that the skeleton and muscles of vertebrates should not be seen as separate but instead are composites, with the boundaries between cell groups blurred around the body. For example, the stem cell group that makes the connective tissues of the swallowing/gulping muscles also makes the skeletal regions ...

Gene Signatures Predict Interferon Response For Multiple Sclerosis Patients

... nerve cells and disrupts normal nerve signaling. Patients experience a wide range of symptoms—including tingling, paralysis, pain, fatigue, and blurred vision—that can appear independently or in combination, sporadically or persistently. Although symptoms appear in no particular order, flare-ups are ...
