OBJECTIVE Bacterial vaginosis is a common infectious disorder. Although known since ancient times, little progress has occurred in identifying causal factors. Our aims were to study the bacterial community structure and the spatial organization of microbiota on the epithelial surfaces of vaginal biopsy specimens. METHODS We investigated the composition and spatial organization of bacteria ass...

L ike soloing rock climbers, adherent cells need a good handhold to survive. Ma et al. now identify an adaptor protein that monitors the cell's grip and signals death if the grip fails. Death following detachment, known as anoikis, is a form of programmed cell death that ensures the disposal of displaced adherent cells. Lack of anoikis is thought to give cells metastatic potential. A number of ...

The objective of this study is to investigate the factors of the initial adherence to PAP, with an emphasis on the role of upper airway narrowing. METHODS The patients were divided into two groups according to the continuation of therapy within the first three ...

Adhesion of myeloid leukemia cells to the bone marrow (BM) microenvironment is mediated in part by Beta 1 and Beta 2 integrins. Cells of the erythroleukemia line K562, derived from a patient with chronic myeloid leukemia, bind to BM fibroblasts (BMFs) but the adhesion cannot be accounted for by integrins or other known adhesion proteins including CD44 or members of the Ig or selectin families. ...

BACKGROUND Radiotherapy (RT) is proven to be an important backbone for adjuvant therapy in randomized, controlled trials, but it is unclear if these effects are provable in a daily routine cohort of breast cancer patients. This study sought to answer the following questions in a daily routine cohort of breast cancer patients: 1. Does guideline-adherent RT improve primary breast cancer patient s...
