This manuscript presents novel approaches to grow and evaluate Streptococcal biofilm formation using the human respiratory pathogen Streptococcus pneumoniae (the pneumococcus) as the main model organism on biological surfaces in vitro and in vivo. Most biofilm models are based on growth on abiotic surfaces, which is relevant for many pathogens whose growth on surfaces or medical devices is a major cause of disease transmission and infections, especially in hospital environments. However, most infections with commensal organisms require biofilm formation on biological surfaces in the host at the site of colonization or infection...

INTRODUCTION: Management of lung cancer remains a challenge. Although clinical and biological patient data are crucial for cancer research, these data may be missing from registries and clinical trials. Biobanks provide a source of high-quality biological material for clinical research; however, linking these samples to the corresponding patient and clinical data is technically challenging. We describe the mobile Lung Cancer Care system (mLCCare), a novel tool which integrates biological and clinical patient data into a single resource...

An increasing interest in applying synthetic biology techniques to program outer membrane vesicles (OMV) are leading to some very interesting and unique applications for OMV where traditional nanoparticles are proving too difficult to synthesize. To date, all Gram-negative bacteria have been shown to produce OMV demonstrating packaging of a variety of cargo that includes small molecules, peptides, proteins and genetic material. Based on their diverse cargo, OMV are implicated in many biological processes ranging from cell-cell communication to gene transfer and delivery of virulence factors depending upon which bacteria are producing the OMV...

In recent years, lifetime measurements by means of the Time Correlated Single Photon Counting (TCSPC) technique have led to a significant breakthrough in medical and biological fields. Unfortunately, the many advantages of TCSPC-based approaches come along with the major drawback of a relatively long acquisition time. The exploitation of multiple channels in parallel could in principle mitigate this issue, and at the same time it opens the way to a multi-parameter analysis of the optical signals, e.g., as a function of wavelength or spatial coordinates...

The treatment therapies and technologies currently emerging from the rapidly evolving health care industry must undergo full examination in a clinical setting if they are to be marketed to the public. All elements of clinical studies involving human subjects must undergo thorough IRB review before study activities can commence. Regulations regarding IRB oversight apply to all clinical studies-including retrospective examinations of private medical data and identifiable biological samples. It is not uncommon for researchers to be unsure whether, or on what level, IRB review and oversight are required for a particular project...

Due to addition of anti-CD20 to anthracycline-based chemotherapy, survival of diffuse large B-cell lymphoma increased during the last decade. Although these trends are encouraging, there are still persistent differences in survival within and between US and European countries suggesting the role of non-biological factors. Our aim was to investigate the influence of such factors on relative survival of diffuse large B-cell lymphoma patients. We conducted a retrospective multicenter registry-based study in France, between 2002 and 2008, on 1165 incident cases of diffuse large B-cell lymphoma Relative survival analyses were performed and data missing were controlled with multiple imputation method...

Patients with early-stage non-small-cell lung cancer (NSCLC) who are unable to undergo surgery can be offered radiation therapy (RT). Previously, conventional RT was offered; however, newer techniques such as stereotactic body RT (SBRT) have become available. The objective of the present systematic review was to investigate the effectiveness of RT with curative intent in patients with early-stage medically inoperable NSCLC. MEDLINE, EMBASE, and the Cochrane Library were searched for studies comparing stereotactic RT with curative intent compared with observation or other types of RT for early-stage, medically inoperable, NSCLC...
