The method involves printing genomic DNA at high density onto a glass slide and uses fluorescently labelled probes to detect target genes.
The report highlights inconsistent data-access policies among nations and agencies, emphasizing the need for international efforts to promote open access. The authors call for an international framework to achieve this goal, making data sharing a rule rather than an exception.
A new tumor classification system combines molecular biology and classic pathology to provide a comprehensive and consistent way of typing tumors. The system uses both the type of cells that form a tumor and its molecular characteristics to determine its behavior, offering improved accuracy and insight into treatment options.
A study found that 71% of Japanese outpatients would like to make treatment decisions in collaboration with their physician. Patients prefer to involve their families in decision-making, but only allow them to support the patient's decision, not provide a third opinion.
Research suggests that hunger increases sensitivity to sugar and salt, as the body tries to consume food. However, this effect does not apply to bitter tastes, which may be more related to detecting toxins.
A new study found that people with short variants of the APOB gene region have significantly lower total and low-density lipoprotein cholesterol levels in their blood. This association may contribute to a protective role of these variants in younger adults, while being detrimental to longevity in older individuals.
Researchers found that tropical boubous sing the 'victory duet' more often after an invasion attempt than before or during playback of recordings. This rare context-specific birdsong is used to assert dominance and deter other birds from intruding into their territory.
Researchers reconstructed the timeline of eukaryotic evolution, showing that increased oxygen led to more varied cell types. Organisms with up to 50 different cell types evolved following the emergence of mitochondria and plastids around 2,300 million years ago.
Gerbrand Izaks and Rudi Westendorp propose a model where diseases are caused by cumulative risk factors, making every age-related change a potential symptom of an illness. This framework encourages doctors to reassess older patients' body functions, comparing results to 'normal values' from healthy young adults.
A population-based study found that infants would benefit most from in-hospital palliative care, while older children with long-term illnesses require community-based and at-home services. Effective end-of-life care for all children needs simultaneous delivery of different modes of care.
A new study has identified a link between the size of apolipoprotein(a), a protein component of low-density lipoprotein, and an increased risk of heart disease in overweight individuals. The research suggests that analyzing apolipoprotein(a) size may provide a reliable way to discriminate between those at high risk and those without.
Researchers discover that retroviral Gag proteins bind tightly to endophilin-2, a protein involved in cell membrane budding. This interaction is crucial for the production and spread of viruses.
