Craniofacial Surgery Gives Tijuana Teen Chance to be 'Normal' Kid

...ur explained. “The dura (dura mater: the outermost membrane covering the brain) was absent in much of the injured area, so I had to create a dural patch graft to protect the brain and to prevent spinal fluid from leaking. We reconstructed the cranium and the base of the skull to make it more prominent and ana...

Sleepy After A Heavy Lunch? Here's Why

... of signals. "We have identified the pore in the membrane of orexin-producing cells that is responsible for the inhibiting effect of glucose. This previously unknown mechanism is so sensitive it can detect minute changes in glucose levels - the type that occurs between meals for example," said lead research...

NOMID Symptoms Helped By Arthritis Drug

...inra. Rash and conjunctivitis (inflammation of the membrane lining the eyelids), both common in NOMID, disappeared within three days. By three months, laboratory measures of inflammation, including erythrocyte sedimentation rate, c-reactive protein and serum amyloid A protein (SAA), had improved, and by six m...

What does High-fiber Foods Really do?

...ly lethal outer-membrane injuries. When an outer membrane tear happens calcium just outside the cell rushes in. Although too much calcium is lethal the first entry of calcium causes several of the internal mucus-filled compartments in epithelial cells to fuse together within about three seconds, forming a p...

Fresh Water Algae Filtered Out With Water Filtration Technique

...the technique, which couples activated carbon with membrane filters, said Hal Walker, associate professor of c...ed to test whether combining activated carbon with membrane filters would do the trick. That technology has already proven effective for removing herbicides and...

Discerning Sour Taste

...ted the taste receptors to be embedded in the cell membrane where they could be in contact with taste molecules on the tongue,” explained Huang. “Therefore, we narrowed the search down to genes for proteins with a structure that would allow them to be in a cell membrane. Second, we ruled out candidates that w...

Carbon Monoxide May Prevent Pre-Eclampsia

Immune Response Linked to “Ghost” Parasites and Severely Congested Sinuss

...ins team took samples during surgery of the mucous membrane lining the nose, and using real-time polymerase chain reaction tests, analyzed the samples for any genetic differences between the groups. When researchers initially compared all the nasal tissue samples, they found that half had the gene for AMCas...

Chronic Sinusitis Resulting From Weakene Immune System

...ins team took samples during surgery of the mucous membrane lining the nose, and using real-time polymerase chain reaction, analyzed the samples for any genetic differences between the groups. 'Surgically treating sinusitis is much like plumbing, in the sense that we try to restore normal sinus cavity drain...

ABCB6 Is Key to Production of Heme in Hemoglobin

...ators showed that ABCB6 is lodged within the outer membrane of the cell’s energy powerhouse called the mitochondria; and that it ferries into mitochondria a type of molecule called a porphryin, a molecule essential for life. A report on these results appears in the advanced online publication of Nature. Ins...

Why Don’t All Moles Progress to Melanoma

...when chains of amino acids are deposited in the ER membrane in response to coded instructions from genes. Chaperone proteins fold these amino acids into specific shapes. When too many of them build up in the membrane, or when something goes wrong with the folding process, the system gets bogged down. This can...

Indian radiologist spearheads cure for osteoarthritis sans surgery

...puterised device called Cytotron to alter the cell membrane potential. "Like other tissues, bone and cartilage are constantly being built-up and broken down by a variety of metabolic and physical influences. The major stimulus for bone and cartilage formation is a piezoelectric signal generated when these s...

A New Option For AIDS Treatment - Radioimmunotherapy

...gamma particles are emitted , and either the cell membrane is ruptured or the essential DNA is damaged during this procedure. It was found that the number of HIV infected cells fell in the treated mice compared to the other mice , which had been given antibodies without a radioactive tag. It was also seen...

Prestigious Wilson Award Goes To Yale Cell Biologist Joel Rosenbaum

Link Between Huntington’s and Abnormal Cholesterol Levels in Brain Establishe

...network among brain cells and in maintaining their membrane integrity. Both the level of cholesterol and its delivery to the proper locations in the cell are essential for the survival of neurons,” explains Mayo Clinic molecular biologist Cynthia McMurrary, Ph.D. “Our discovery that the mutant Huntington’s ...

Enzyme to Boost Effect of Tumor Vaccine

...that it targeted a particular domain on the plasma membrane of the cell where signaling occurred, making the action of Akt1 more specific. They then eliminated a small part of the Akt1 molecule that had a negative or inhibitory effect. 'It turned out that the altered molecule was much more potent,' Spencer sa...

Durable Critters Provides Better Way to Human Egg Preservation

...ration. Lipids or fats in the egg can fuse and the membrane can become leaky. The bottom line is only about 1-5 percent of eggs develop to term after standard cryopreservation techniques, which include a combination of slow freezing in conjunction with low levels of cryoprotectants such as dimethyl sulfoxid...

Study Finds Astaxanthin Is Potent Inhibitor of Oxidation in Cell Membrane Model

...based on its exceptional antioxidant properties in membrane models. Combined with published proof-of-concept,...ffects of carotenoids on lipid peroxidation due to membrane interactions; xray diffraction analysis by McNulty et al.) signify that astaxanthin exhibits potenti...

Dual Gene Therapy Suppresses Lung Cancer in Preclinical Test

...re delivered to the negatively charged cancer cell membrane and taken into the cell, where the genes repeatedly express either p53 or FUS1 tumor-suppressing proteins. Roth expects the research team to advance combination therapies to clinical trials in the coming years, either of genes or of genes with oth...
