New England Peptide (NEP), a Massachusetts based biotech manufacturer, and The Atlantic Cancer Research Institute (ACRI), a leading cancer research center in Atlantic Canada, have launched a new biotech company. Excipio Technologies Inc. has a mandate to commercialize the Vn96 peptide developed by both NEP and ACRI for the isolation of exosomes and extracellular microvesicles. Gardner, MA (PRWEB) December 13, 2013 Vn96 is a synthetic peptide that was designed to specifically stick to...

Astronauts Diagnosed With Eye Problems After Returning From Space
2013-12-11 16:34:15

NASA Those who travel to space are rewarded with a beautiful sight – planet Earth. But the effects of space travel on the human sense of sight aren’t so beautiful. More than 30 percent of astronauts who returned from two-week space shuttle missions and 60 percent who spent six months aboard the International Space Station were diagnosed with eye problems. Two recent investigations examined mechanisms that may explain eye changes in spaceflight, help find ways to minimize this health...

Shifts in zinc's location could be exploited for early diagnosis of prostate cancer Zinc, an essential nutrient, is found in every tissue in the body. The vast majority of the metal ion is tightly bound to proteins, helping them to perform biological reactions. Tiny amounts of zinc, however, are only loosely bound, or "mobile," and thought to be critical for proper function in organs such as the brain, pancreas, and prostate gland. Yet the exact roles the ion plays in biological systems...

Intracellular ABC Transporters Allow Leaf Beetle Larvae To Accumulate Defensive Substances When Feeding

Max Planck Institute for Chemical Ecology Similar membrane proteins play a crucial role in the transport of toxic substances out of the cell Scientists at the Max Planck Institute for Chemical Ecology in Jena, Germany, have discovered the decisive biological stimulator for the accumulation of defensive substances in leaf beetle larvae used by the insects to fend off predators: ABC transport proteins, which are found in large quantities in glandular cells of the larvae. The poplar leaf...

Tokyo, Nov 29, 2013 - (ACN Newswire) - Researchers at Waseda University in Japan have identified key information to help explain the formation of the "spindle apparatus", a structure required for cell division. Their findings shed light on the mechanisms behind "self-organization" - an essential characteristic of biological structures.Organisms are composed of a variety of structures including muscles, internal organs, and brains, all of which are created through a process known as...

[ Watch The Video: Capturing the Carboxysome in Motion ] DOE/Joint Genome Institute Cyanobacteria, found in just about every ecosystem on Earth, are one of the few bacteria that can create their own energy through photosynthesis and "fix" carbon – from carbon dioxide molecules – and convert it into fuel inside of miniscule compartments called carboxysomes. Using a pioneering visualization method, researchers from the University of California, Berkeley and the Department of Energy...

Study Sheds Light On Treatment For Parkinson's Disease
2013-11-25 07:02:43

NIH/National Institute of Neurological Disorders and Stroke Scientists at the National Institutes of Health have used RNA interference (RNAi) technology to reveal dozens of genes which may represent new therapeutic targets for treating Parkinson's disease. The findings also may be relevant to several diseases caused by damage to mitochondria, the biological power plants found in cells throughout the body. "We discovered a network of genes that may regulate the disposal of dysfunctional...

Tokyo, Nov 25, 2013 - (ACN Newswire) - Researchers at Waseda University in Japan have for the first time directly observed the "molecular motor", called Xkid, that plays a critical role in facilitating the proper alignment of chromosomes during cell division. Their findings are expected to contribute greatly to elucidating the molecular mechanisms of chromosome segregation, a key aspect of the development of certain medical disorders including cancer and birth defects.A human being begins as...

Muscle movements generate body heat. However, body heat can also be generated in another way: body fat contains a small number of brown adipose cells – special fat cells that can generate heat without muscle activity. They do this using a protein known as UCP1 that enables babies or hibernating animals to keep warm without shivering. A research team at the University of Veterinary Medicine (Vetmeduni Vienna) has found that a specific chemical compound, an aldehyde, can activate UCP1 under...


Word of the Day
Cthulhu
  • A gigantic fictional humanoid alien god being described with a head resembling an octopus and dragon wings and claws, around whom an insane cult developed.
  • Pertaining to the mythos of Cthulhu and additional otherworldly beings created by H. P. Lovecraft or inspired by his writings and imitators.
This word was invented in 1926 by H.P. Lovecraft for his short story, 'The Call of Cthulhu.' 'Cthulhu' may be based on the word 'chthonic,' which in Greek mythology refers to the underworld.
