Microbiome may hold key to identifying HPV-infected women at risk for pre-cancer

Gardnerella bacteria in the cervicovaginal microbiome may serve as a biomarker to identify women infected with human papillomavirus (HPV) who are at risk for progression to precancer, according to a new study.

Experiments in mice and human cells shed light on best way to deliver nanoparticle therapy for cancer

Researchers in the cancer nanomedicine community debate whether use of tiny structures, called nanoparticles, can best deliver drug therapy to tumors passively -- allowing the nanoparticles to diffuse into tumors and become held in place, or actively -- adding a targeted anti-cancer molecule to bind to specific cancer cell receptors and, in theory, keep the nanoparticle in the tumor longer. Now, new research on human and mouse tumors in mice suggests the question is even more complicated.

High-speed microscope captures fleeting brain signals

Neuroscientists can now capture millisecond electrical changes in neurons in the cortex of an alert mouse, allowing tracing of neural signals, including subthreshold events, in the brain. The new technique combines all-optical scanning with two-photon fluorescence imaging to produce a 2D rasterized picture every 1,000-3,000 milliseconds. That and another technique that allows 3D imaging of large areas of the mouse cortex to a depth of 650 microns will aid study of neural circuits.

Ball-and-chain inactivation of ion channels visualized by cryo-electron microscopy

Ion channels, which allow potassium and sodium ions to flow in and out of cells, are crucial in neuronal 'firing' in the central nervous system and for brain and heart function. These channels use a ''ball-and-chain'' mechanism to help regulate their ion flow, according to a new study.

Tomosynthesis outperforms digital mammography in five-year study

A new study has found that the advantages of digital breast tomosynthesis (DBT) over digital mammography (DM), including increased cancer detection and fewer false positive findings, are maintained over multiple years and rounds of screening. In addition, research showed that DBT screening helped detect a higher proportion of poor prognosis cancers than DM.

Researchers help restore hormonal balance disrupted in metabolic diseases

Many health problems in the developed world stem from the disruption of a delicate metabolic balance between glucose production and energy utilization in the liver. Now scientists report that they have discovered the molecular mechanisms that trigger metabolic imbalance between these two distinct but linked processes, a finding with implications for the treatment of diabetes and non-alcoholic fatty liver disease.
