Human alveolar lining fl uid from the elderly promotes Mycobacterium tuberculosis intracellular growth and translocation into the cytosol of alveolar epithelial cells

The elderly population is highly susceptible to developing respiratory diseases, including tuberculosis, a devastating disease caused by the airborne pathogen Mycobacterium tuberculosis ( M.tb ) that kills one person every 18 seconds. Once M.tb reaches the ...

Using flow cytometry and light-induced fluorescence to characterize the variability and characteristics of bioaerosols in springtime in Metro Atlanta, Georgia

Athanasios Nenes

The abundance and speciation of primary biological aerosol particles (PBAP) is important for understanding their impacts on human health, cloud formation, and ecosystems. Towards this, we have developed a protocol for quantifying PBAP collected from large ...

Vibrio cholerae filamentation promotes chitin surface attachment at the expense of competition in biofilms

Alexandre Louis André Persat

Collective behavior in spatially structured groups, or biofilms, is the norm among microbes in their natural environments. Though biofilm formation has been studied for decades, tracing the mechanistic and ecological links between individual cell morpholog ...

Miniature hyperspectral systems

Dragos Constantin

Spectroscopy methods have been used for decades to obtain information about various materials, ranging from galaxies billions of light years from earth, to Petri dishes containing rich bacteria cultures. From spectrometers in chemical labs to spectral came ...

Detection of Vibrio cholerae O1 and O139 in environmental waters of rural Bangladesh: a flow-cytometry-based field trial

Andrea Rinaldo, Enrico Bertuzzo, Lorenzo Mari, Lorenzo Righetto, Marino Gatto

Presence of Vibrio cholerae serogroups O1 and O139 in the waters of the rural area of Matlab, Bangladesh, was investigated with quantitative measurements performed with a portable flow cytometer. The relevance of this work relates to the testing of a field ...

Monitoring system for cell culture

Yann Barrandon, Eric Meurville, Georges Abou Jaoudé

Cell culture environment monitoring system (6) for monitoring parameters relevant to cell growth in at least one culture dish (4) containing a cell growth medium (14), including at least one sensing device (22, 22') configured to measure environmental para ...

Micro-engineering the Cerebral Cortical Cell Niche : A new Cell Culture Tool for Neuroscience Research

Anja Kunze

A major problem in traditional cell culture methods, such as Petri dishes and culture flasks, is the very simplified artificial environment around the cells. Traditional cell culture methods lack features of the native cell niche, such as gradients and cel ...

Frequent concomitant presence of Desulfitobacterium spp. and “Dehalococcoides” spp. in chloroethene-dechlorinating microbial communities

Christof Holliger, Julien Maillard, Katia Szynalski

The presence of chloroethene dechlorination activity as well as several bacterial genera containing mainly organohalide respiring members was investigated in 34 environmental samples from 18 different sites. Cultures inoculated with these environmental sam ...

Highly Sensitive Carbon Nanotube-Based Sensing for Lactate and Glucose Monitoring in Cell Culture

Giovanni De Micheli, Sandro Carrara, Cristina Boero, Giovanna Del Vecchio

Monitoring of metabolic compounds in cell cultures can provide real-time information of cell line status. This is particularly important in those lines not fully known, as the case of embryonic and mesenchymal cells. On the other hand, such approach can pa ...

Biomaterials: Spotlight on hydrogels

Matthias Lütolf

By using light to control the degradation of hydrogel components in space and time, researchers have generated a tool to help them reconstruct functional biological tissues in a culture dish. ...
