New Malaria Treatment

...have been able to treat severe malaria in rats and primates effectively; it now remains to be seen whether these results can be replicated in people. "There's often a lack of ability to treat people suffering from severe malaria," says Professor Wahlgren. "We've developed a substance that might be able to he...

Calorie Restriction May Prevent, Reduce Alzheimer’s Neuropatholog

... investigation of calorie restriction in non-human primates may be a valuable approach towards understanding the role of calorie restriction in human AD pathology. The present study strengthens the possibility that calorie restriction may exert beneficial effects in delaying the onset of AD. The findings also...

Major Shake up needed in HIV Vaccine Research

...uses to the immune systems of humans and non-human primates will play an important part in helping us develop an effective vaccine. Barré-Sinoussi also stressed the importance of future research into the therapeutic vaccination of HIV-infected patients on highly active antiretroviral therapy (HAART)....

A Protein from Primate may Save Humans from HIV !

...ns, which are no longer made by humans or advanced primates such as chimpanzees. However, theta-defensins are more active against HIV-1 than the other two types of defensins and can be developed in laboratories, two features that suggest retrocyclins still could become an effective way to fight the virus. H...

Transplanted Pancreatic Tissue Could Help Diabetics

...s to transplant such animal tissues into non-human primates have evoked a fierce immune response. However, embryonic tissues, such as those from pigs (in which the insulin-producing cells are similar to those of humans), might not be rejected as strongly. New research by Prof. Yair Reisner of the Weizmann Ins...

Brain’s response distinct upon exposure to erotic image

...reacting to these visual scenes. Recent studies in primates recorded the electrical activity of single neural cells within the brain and have shown that the frontal cortex contains neurons that can discriminate between different categories of visual objects such as dogs versus cats. Whether or not the human p...

To Ape or Not To Ape? Bridging Missing Links in Medical Research

...t the simmering issue deals with the idea of using primates in medical research.// The reason for the yo-yoing on the issue of using primates in medical testing hovers around their extreme likeness with humans. Primate testing has triggered...

Neurological Damage Can Be Reduced By Stem Cell Transplants

...to test their treatment in larger animals, such as primates and pigs. Stating that there's no indication yet that the treatment will work in humans, and the lead researcher cautioned that the claimed treatment would not be a easy as thought. However, tests in people could begin as early as next year, they ho...

Early Man Was A Prey Rather Than A Predator

...prey rather than a predator, "In fact, all diurnal primates (those active during the day) live in permanent social groups. Most ecologists agree that predation pressure is one of the major adaptive reasons for this group living. In this way there are more eyes and ears to locate the predators and more individ...

Earth Will Feel The Impact Of Global Warming

...is time-including evidence of the first horses and primates in North America and Europe, which were possibly allowed by warm conditions that opened travel routes which were not possible under previously colder climates, the study said. Researchers said that modern carbon dioxide input from fossil fuel sour...

New Procedure Reveals the Secrets of the Brain

...microstimulation/MRI technique in conscious, alert primates holds great promise for determining the causal relationships between activation patterns across distributed neuronal circuits and specific behaviors. This method could also prove useful in understanding and optimizing the method of intra-cranial el...

In addition to hyperacute rejection by the human immune system, other hurdles facing xenotransplantation include delayed rejection, coagulopathy and chronic...

Exercise Affects Alertness

Researchers say they used monkeys for their study because they did not want environmental factors such as smoking, drinking, and obesity to play a role. The animals were separated into t...

Fossil teeth and human development
