It is known that teeth can protect themselves, to some extent, from attack by bacteria but that inflammation within a tooth can be damaging and, in extreme cases, lead to abscess or death of the tooth. New research published in BioMed Central's open access journal BMC Immunology shows that odontoblast cells are part of the immune system and fight to protect teeth from decay. Inside a tooth odontoblast cells sit between the enamel and pulp and produce a layer of dentin to protect the pulp from...

What makes music beautiful? The best compositions transcend culture and time "“ but what is the commonality which underscores their appeal? New research published in BioMed Central's open access journal BMC Research Notes suggests that the brain simplifies complex patterns, much in the same way that 'lossless' music compression formats reduce audio files, by removing redundant data and identifying patterns. There is a long held theory that the subconscious mind can recognise patterns...

Society has long debated the contrasting advantages of monogamy and promiscuity and, in western society at least, the long term benefits of monogamy have in general won out. However new research published in BioMed Central's open access journal BMC Evolutionary Biology shows that sperm from polygamous mice are better competitors in the race for fertilisation. Dr Ren©e Firman at the Centre for Evolutionary Biology, University of Western Australia, has used house mice to show that sperm...

Potential gender differences in clinical management are under-researched. A systematic analysis of the incorporation of sex and gender into research design, published in the open access journal BMC Medicine, has found that, although there has been a progressive improvement since the 90s, there exists a striking under-representation of research about gender differences in patient management. Sabine Oertelt-Prigione, from the Institute of Gender in Medicine, Berlin, worked with a team of...

Ultrasound can speed the healing of fractures. A randomized controlled trial reported in the open access journal BMC Musculoskeletal Disorders has found that the use of low-intensity pulsed ultrasound (LIPUS) in patients with tibial fractures which showed inadequate progress toward healing resulted in 34% greater bone mineral density (BMD) in the fracture area after 16 weeks than use of a sham device. Jon E. Block, Ph.D. worked with a team of researchers from University Hospital Marburg and...

In mice, early weaning and separation from their mothers promotes long-lasting hyperactivity and anxiety . Researchers writing in the open access journal BMC Neuroscience describe the development of this new behavioral model, which they hope to use to investigate the long-term effects of early childhood neglect in people. Arthur Simen and a team of researchers from Yale University School of Medicine, USA, tested their 'Maternal separation with early weaning' (MSEW) model in a group of 80 male...

Blood alcohol levels below the current legal limit for driving have a significant negative effect on a person's dexterity. Researchers writing in the open access journal BMC Research Notes found that just two single vodka and orange drinks were enough to make senior volunteers struggle at an obstacle avoidance test while walking. Judith Hegeman worked with a team of researchers from Sint Maartenskliniek, Nijmegen, The Netherlands, to carry out the tests in 13 healthy men and women (average...

Less-pretty female house sparrows tend to lower their aim when selecting a mate. Addressing the lack of studies on condition-dependency of female mate choice, researchers writing in the open access journal BMC Evolutionary Biology found that female sparrows of a low quality prefer males of an equally low quality. Researchers from the Konrad Lorenz Institute for Ethology in Vienna studied sexual selection preferences in the common house sparrow. Though it has always been assumed that females...

Clinical depression and anxiety during pregnancy results in smaller babies that are more likely to die in infancy, according to new research published in the open access journal BMC Public Health. The study, which focused on women living in rural Bangladesh, provides the first finding of its kind in a non-Western population. The research indicates that mental health issues are likely to be a primary contributor to infant mortality and poor child health, above poverty, malnutrition or low...

The placement of alcohol-based hand disinfectants in businesses can reduce illness and absenteeism amongst the work force. A study published in the open access journal, BMC Infectious Diseases, has found that incidences of absenteeism in public administrations due to the common cold, fever and cough are significantly reduced when alcohol-based hand disinfectants are used by employees. Nils-Olaf Hbner and a team from Germany analyzed absenteeism and symptom data from 129 participants. He said,...
