Optical coherence tomography measures changes in retinal cone cells

Humans see color thanks to cone cells, specialized light-sensing neurons located in the retina along the inner surface of the eyeball. The actual light-sensing section of these cells is called the outer segment, which is made up of a series of stacked discs, each about 30 nanometers (billionths of a meter) thick. This appendage goes through daily changes in length.

New method uses cultured skin cells to detect contact allergy

Contact allergy affects around 20% of the population in the western world. Scientists are working intensively to develop alternative test methods that do not require animal testing. A research group at the University of Gothenburg, Sweden, has now developed a unique test method that enables graded results to be obtained using cultured skin cells.

CSF biomarkers can help detect early stage of Alzheimer's

Analysis of the cerebrospinal fluid can detect whether a person has Alzheimer's disease before symptoms appear. Researchers at the Sahlgrenska Academy at the University of Gothenburg, Sweden, have studied biomarkers that offer more reliable diagnosis and, in the longer term, the possibility of effective new treatments.

BMDCs can contribute to olfactory neurons through plasticity mechanism

Bone marrow-derived stem cells (BMDCs) have been recognized as a source for transplantation because they can contribute to different cell populations in a variety of organs under both normal and pathological conditions.

Study examines relationship between malaria, salmonella infection

People with malaria are more prone to developing bacterial infections, particularly from salmonella, and "researchers at the London School of Hygiene & Tropical Medicine [LSHTM] have discovered that the increased vulnerability to salmonella infections is a side effect of the body's attempts to protect itself from the damaging effects of the malaria infection," according to an LSHTM press release.

EETs may also drive growth and spread of cancer

A group of small molecules called EETs - currently under scrutiny as possible treatment targets for a host of cardiovascular diseases - may also drive the growth and spread of cancer, according to researchers at the Dana-Farber/Children's Hospital Cancer Center (DF/CHCC) and other institutions.

Math model reveals that spatial tissue structure delays tumor formation

Cancer growth normally follows a lengthy period of development. Over the course of time, genetic mutations often accumulate in cells, leading first to pre-cancerous conditions and ultimately to tumour growth. Using a mathematical model, scientists at the Max Planck Institute for Dynamics and Self-Organization in G-ttingen, University of Pennsylvania and University of California San Francisco, have now shown that spatial tissue structure, such as that found in the colon, slows down the accumulation of genetic mutations, thereby delaying the onset of cancer.

Lostartan can reduce cigarette smoke-induced lung injury

Chronic obstructive pulmonary disease (COPD) is among the most common causes of death in the US. It is a smoking-related disease for which there are currently no disease-altering therapies. However, hope that one could be developed is now provided by the work of Enid Neptune and colleagues, at Johns Hopkins University, Baltimore, in a mouse model of lung disease caused by exposure to cigarette smoke.

Acupuncture can reduce protein associated with chronic stress

Acupuncture significantly reduces levels of a protein in rats linked to chronic stress, researchers at Georgetown University Medical Center (GUMC) have found. They say their animal study may help explain the sense of well-being that many people receive from this ancient Chinese therapy.
