Prenatal Stress Keeps Infants, Toddlers up at Night, Study Says

...ies exist, and unlike medication, none of them are suspect in the least for causing adverse effects to baby. Given prenatally, psychological interventions could instill a whole host of benefits that may carry-over to the child, OConnor said. Still, more clinical research is needed to see how we can best...

Potent possibilities for parasite attack

...however, are evolving rapidly, leading the team to suspect they include key genes involved in interacting with the human host - where the battle between parasite and patient is fought and where rapid response is important to both. Remarkably, L. braziliensis, the most ancient Leishmania species sequenced,...

Clot-dissolving agent may be beneficial in treatment of severe frostbite

...se of tPA in frostbite injury.” The researchers suspect tPA helps reduce the injury caused when frozen skin is warmed again. Inflammation during thawing typically stimulates clotting that blocks small blood vessels, leading to cell death. Because tPA reverses this clotting, blood flow is restored before p...

Common treatment for methamphetamine overdose may damage brain cells

...d his team at Boston University School of Medicine suspect the damage results from the exaggerated stimulation of cells by the amino acid glutamate, which proves toxic to cells producing the neurotransmitter gamma-aminobutyric acid (GABA). Their results are published in the May 30 issue of The Journal of Ne...

Corals -- More complex than you?

...ce of this may lie in the fact that scientists now suspect coral is facing a number of pandemics: ‘black band? ‘white plague? ‘white pox?‘white syndrome?and ‘white band?are the names of some of these diseases. "The coral immune system is a black box at present. How corals cope with the worldwide upsurge i...

An ancient bathtub ring of mammoth fossils

...ut the history of Ice Age flooding." Geologists suspect that most of the Ice Age floods in eastern Washington originated from glacial Lake Missoula. The lake formed behind ice that dammed the Clark Fork River. Sometimes the ice dam broke, releasing huge volumes—up to 500 cubic miles—of water in an instant...

Growing nerve cells in 3-D dramatically affects gene expression

... stuck; they move. As a result, some scientists suspect that hothouse cells do not behave like in vivo varieties. This means that the critical functions scientists are trying to understand by studying these cells ?from the proliferation of cancer to the bacterial assault by antibiotics ?may play out diffe...

Fast and slow -- How the spinal cord controls the speed of movement

...s and muscles that allow for faster movement. They suspect that damage to these brain cells may disrupt the release of dopamine, further complicating free movement. Fetcho and his group are building a transgenic line of fish with those brain cells labeled so they may be targeted and removed with lasers....

UCLA study uncovers clues for why Graves' disease attacks the eyes

...After two or three generations of this process, we suspect that the high-jacked T-cells mutiny over the normal T-cells, sparking the body’s immune reaction against itself." The next step is to identify what the T-cells are reacting to and how the receptor enables the cells to survive beyond their normal...

Mutation improves memory, may lead to memory-enhancing pill

...n training conditions. “Those results led us to suspect that decreasing the phosphorylation of eIF2a enhanced memory storage,?Costa-Mattioli said. In an effort to validate their earlier findings, the researchers have now generated mice carrying a version of eIF2a that cannot be phosphorylated. The muta...

Pitt study notes decline in male births in the US and Japan

...ave children and the health of their offspring. We suspect that some combination of these factors, along with older age of parents, may account for decreasing male births.? Dr. Davis explained that environmental factors, such as prenatal exposure to endocrine- disrupting environmental pollutants may impa...

Researchers identify ovarian cancer biomarkers

..., were also prognostic of a patient's survival. We suspect when these genes are highly expressed it may be a sign of a tumor that's able to grow blood vessels more efficiently, and therefore is more aggressive. This may help us down the road in treatment decisions," says lead study author Ronald Buckanovich,...

Hybrid molecule causes cancer cells to self-destruct

...ancer cells did not self-destruct. The researchers suspect this is because the hybrid molecules more easily penetrate the surface of the cell than the individual chemicals. Once the components are inside, the researchers believe the partners help enzymes to resume the normal assembly of sugar molecules and c...

Chemo combination improves survival in asbestos-related cancer

... are still from pre-OSHA workplace improvements. I suspect that modern asbestos abatement precautions will avoid most, if not all, future cases. The latency is over 30 years, so we are still diagnosing cases with exposure during World War II and the '40s and '50s." Mesothelioma is difficult to diagnose, G...

New mechanism for nutrient uptake discovered

...en in our kidneys, which excrete nitrogen. We also suspect other different types of transporters will be discovered to work in this way." The scientists don't yet know what triggers the rapid shut-off. They think it might be a very common regulatory event called phosphorylation, where a phosphate molecule...

Infection detectives use disease 'fingerprints' to track common infections in children

...cal Center have found a new method for identifying suspect viruses and bacteria that cause some of the most common acute infections in children. Traditionally, researchers have looked for clues to an infection by tracking down the virus or bacteria causing it. But that doesn’t always work because the bact...

Hay fever can send work productivity down the drain

...issing work. Szeinbach suggests that people who suspect they have hay fever get an allergy test, either from a family doctor or an allergist. In previous work, she found that some people with allergy-like symptoms don't actually have allergies. Almost anything can cause allergy-type symptoms - perfumes, s...

Biologists call for better choice of model organisms in 'evo-devo'

... is because too much was expected too soon, but we suspect that in terms of its future promise the current choice of new model organisms has not yet been optimised. Dr Wills said: "Many models to date, in particular the big six, have been chosen because they are easy to keep in the laboratory, select and ...

Major link in brain-obesity puzzle found

...lity to make SH2B1 in their fat cells, the authors suspect that fat-cell SH2B1 encourages the storing of fat. When they tested this theory, they found that SH2B1 appeared to help mouse embryonic cells turn into fat cells, a process called adipogenesis. But, they suspect, the action of SH2B1 in the brain trum...

How fish mend a broken heart

In an earlier study, Poss and his colleagues found that zebrafish have a unique ability to regenerate cardiac muscle after major injury. Th...
