Researchers design engineered organ study the use of nanoparticles in breast cancer detection

Purdue University researchers have reproduced portions of the female breast in a tiny slide-sized model dubbed "breast on-a-chip" that will be used to test nanomedical approaches for the detection and treatment of breast cancer.

Simple means of improving binding affinity of synbodies

Antibodies are watchdogs of human health, continuously prowling the body and registering minute changes associated with infection or disease with astonishing acuity. They also serve as biochemical memory banks, faithfully recording information about pathogens they encounter and efficiently storing this data for later use.

Research finds faster developmental rate incurs lethal physiological costs for individuals

Fast development is often perceived as an advantage, as it enables better harmony with one's environment and readiness to cope with the challenges that it poses. However, research conducted at the University of Haifa, Israel, and University of California, Santa Cruz, and published in the scientific journal PLoS ONE, found that the acceleration of developmental rate incurs potentially lethal physiological costs for the developing individual.

New investigative tool may explore intracellular processes with unprecedented clarity

Nongjian Tao and his colleagues at the Biodesign Institute at Arizona State University have pioneered a new technique capable of peering into single cells and even intracellular processes with unprecedented clarity.

New research reveals dynamics behind signal transmission in brain

Surprising rate at which neuronal networks in the cerebral cortex delete sensory information. The dynamics behind signal transmission in the brain are extremely chaotic. This conclusion has been reached by scientists from the Max Planck Institute for Dynamics and Self-Organization at the University of Göttingen and the Bernstein Center for Computational Neuroscience Göttingen.

Bax factor that promotes cell death is also involved in regulating mitochondria behavior

New research led by UC Davis scientists provides insight into why some body organs are more susceptible to cell death than others and could eventually lead to advances in treating or preventing heart attack or stroke.

University of California study may shed light on human ability to adapt hypoxia

In an important study that may shed light on human ability to adapt to hypoxia, or inadequate levels of oxygen, researchers at the University of California, San Diego School of Medicine have proven that the genome of flies exposed to long-term hypoxia are changed to permanently affect gene expression.

New study shows biomarker test can aid in early, precise diagnosis of melanoma

A new study shows that a test of biomarkers for DNA methylation is technically feasible and could aid in earlier, more precise diagnosis of melanoma.

Women pregnant after egg donation are high-risk patients

Women who have become pregnant after egg donation should be categorized as high-risk patients. Why that is the case, and which consequences egg donation may have for women is the subject of a review article by Ulrich Pecks and co-authors from the University Hospital Aachen in the current issue of Deutsches Ärzteblatt International.

Rogue gene blocked by right drugs could stop cancer

Scientists at the University of East Anglia (UEA) have discovered a rogue gene which - if blocked by the right drugs - could stop cancer in its tracks.

Breakthrough in understanding mechanisms behind hereditary alpha-1-antitrypsin deficiency

Researchers from the Royal College of Surgeons in Ireland (RCSI) and Beaumont Hospital have made a breakthrough in understanding the mechanisms behind the most severe form of hereditary emphysema and how protein treatments can improve the condition. The findings of this study may also lead to new treatments for patients with smoker's emphysema.

Contagious cancer repairs own genetic mutations

A curious contagious cancer, found in dogs, wolves and coyotes, can repair its own genetic mutations by adopting genes from its host animal, according to a new study in the journal Science.

Exiqon launches new Hi-Power microRNA labeling kits

Exiqon, a leading supplier of high-value gene expression analysis products, today announced the launch of the 3rd generation of miRCURY LNA microRNA Labeling Kit called Hi-Power for labeling of microRNAs for downstream hybridization to microRNA arrays.

Nutrient 'biomarkers' may help assess nutrient status of elderly people at risk for dementia

Research is trying to determine whether Alzheimer's disease might be slowed or prevented with nutritional approaches, but a new study suggests those efforts could be improved by use of nutrient "biomarkers" to objectively assess the nutrient status of elderly people at risk for dementia.

Mystery of 'inactive' defensin solved

Under standard laboratory conditions, the human beta-defensin 1 (hBD-1), a human antibiotic naturally produced in the body, had always shown only little activity against microbes. Nevertheless the human body produces it in remarkable quantities.

Psychological Science journal releases new research findings

The insula has been implicated in evaluative and affective processes. New findings indicate that the insula may be broadly involved in integrating affective and cognitive processes. Participants rated the positivity and negativity of picture stimuli and how emotionally arousing they found the pictures to be.

Research findings reveal HIV's hiding spot, new way to stop the virus

HIV adapts in a surprising way to survive and thrive in its hiding spot within the human immune system, scientists have learned. While the finding helps explain why HIV remains such a formidable foe after three decades of research - more than 30 million people worldwide are infected with HIV - it also offers scientists a new, unexpected way to try to stop the virus.

Functional tests are necessary to understand human disease despite genetic sequencing

Despite what you might have heard, genetic sequencing alone is not enough to understand human disease. Researchers at Duke University Medical Center have shown that functional tests are absolutely necessary to understand the biological relevance of the results of sequencing studies as they relate to disease, using a suite of diseases known as the ciliopathies which can cause patients to have many different traits.

Researchers identify key player that lead to increased bleeding in diabetes patients with stroke injury

Strokes are a leading cause of mortality and adult disability. Those that involve intracerebral hemorrhage are especially deadly, and there are no effective treatments to control such bleeding. Moreover, diabetes and hyperglycemia are associated with increases in bleeding during hemorrhagic stroke and worse clinical outcomes.

Stusy: HEPA filters may help reduce pollution-related cardiovascular health risks

Using inexpensive air filters may help reduce cardiovascular disease risk that results from exposure to air pollution, according to researchers from Canada, who studied healthy adultsliving in a small community in British Columbia where wood burning stoves are the main sources of pollution.
