Introduction: Dizziness may be associated with negative health outcomes. This study aimed to determine the associations between dizziness and mental and physical health outcomes in middle-aged and older community-dwelling adults in India. Methods: Cross-sectional data from 72,262 individuals (≥ 45 years) of the Longitudinal Ageing Study in India (LASI) Wave 1 in 2017-2018 were analyzed. Dizzin...

Quorum sensing is a process by which bacteria release and subsequently respond to signal molecules, as a mechanism for sensing population density (4). Acylated homoserine lactones (AHLs) are well-studied quorum-sensing signals among proteobacteria and are most commonly synthesized by enzymes of the LuxI family (3). AHLs are usually recognized by members of the LuxR family of transcription facto...

Using the 2010 pilot study of the Longitudinal Aging Study in India (LASI), we examine the socioeconomic and behavioral risk factors for poor cardiovascular health among middle-aged and older Indians, focusing on self-reported and directly measured hypertension. The LASI pilot survey (N=1,683) was fielded in four states: Karnataka, Kerala, Punjab, and Rajasthan. These four states were chosen to...

Seepage meters, like most benthic flux chamber techniques, come with inherent concerns about how their presence may alter the environment and flow regimen of the benthic boundary layer and underlying sediments. Flow due to wave and current movement across topographic features induces a downward and upward flow field within the sediments surrounding the feature. We found this Bernoulli-induced f...

Quorum sensing (QS) systems communicate bacterial population and stimulate microbial pathogenesis through signaling molecules. Inhibition of QS signals potentially suppresses microbial infections. Antimicrobial properties of Streptomyces have been extensively studied, however, less is known about quorum sensing inhibitory (QSI) activities of Streptomyces. This study explored the QSI potential o...

The LaSIE (Large Scale Information Extraction) system has been developed at the University of Sheffiel d as part of an ongoing research effort into information extraction and, more generally, natural languag e engineering . LaSIE is a single, integrated system that builds up a unified model of a text which is then used t o produce outputs for all four of the MUC-6 tasks . Of course this model m...

BACKGROUND/AIMS Pseudomonas aeruginosa (PA) is one of the major opportunistic pathogens which can cause chronic lung infection of cystic fibrosis (CF). The formation of PA biofilm promotes CF development and restricts the antimicrobial efficacies of current antibiotics. METHODS The antimicrobial effects of azithromycin (AZM) and berberine (BER) alone and in combination were evaluated using mi...

Pseudomonas aeruginosa is the predominant microorganism in chronic lung infection of cystic fibrosis patients. The chronic lung infection is preceded by intermittent colonization. When the chronic infection becomes established, it is well accepted that the isolated strains differ phenotypically from the intermittent strains. Dominating changes are the switch to mucoidity (alginate overproductio...

The present study was undertaken in order to understand more about the interaction occurring between S. maltophilia and P. aeruginosa, which are frequently co-isolated from CF airways. For this purpose, S. maltophilia RR7 and P. aeruginosa RR8 strains, co-isolated from the lung of a chronically infected CF patient during a pulmonary exacerbation episode, were evaluated for reciprocal effect dur...
