BACKGROUND Aeromonas hydrophila is a serious pathogen and can cause hemorrhagic septicemia in fish. To control this disease, antibiotics and chemicals are widely used which can consequently result in "superbugs" and chemical accumulation in the food chain. Though vaccine against A. hydrophila is available, its use is limited due to multiple serotypes of this pathogen and problems of safety and ...

The shoot endophytic biocontrol strain Pseudomonas chlororaphis subsp. aurantiaca PB-St2 produces a wide range of exoproducts, including enzymes and antibiotics. The production of exoproducts is commonly tightly regulated. In order to get a deeper insight into the regulatory network of PB-St2, the strain was systematically investigated regarding its quorum sensing systems, both on the genetic a...

Quorum sensing, a process of bacterial cell-cell communication, relies on production, detection, and response to autoinducer signaling molecules. LuxN, a nine-transmembrane domain protein from Vibrio harveyi, is the founding example of membrane-bound receptors for acyl-homoserine lactone (AHL) autoinducers. We used mutagenesis and suppressor analyses to identify the AHL-binding domain of LuxN a...

We have identified a strain of C. neteri SSMD04 isolated from pickled mackerel sashimi that 11 produced N-acyl-homoserine lactone (AHL) type quorum sensing (QS) activity. Tandem mass 12 sspectrometry revealed that C. neteri SSMD04 produced N-butyryl-homoserine lactone (C4-HSL). 13 We identified a pair of luxIR homologues in this genome that shares the highest similarity with croIR 14 from Citro...

In this paper, we discuss about hyperspectral image processing where it plays an important role in remote sensing, hyperspectral verses multispectral image processing and image classifications. Where these classifications includes image sensors, image preprocessing, object detection, object segmentation, feature extraction and object classification. Mainly there are two types of classifications...

Avian pathogenic E. coli (APEC) caused avian colibacillosis is mostly common in poultry industry worldwide. APEC virulence factors lead to pathogenesis and the quorum sensing (QS) system actively involved regulation of these factors. Signaling molecules QS are known as autoinducers (AIs). In QS-1, encodes a single LuxR homolog, i.e., SdiA, but does not express LuxI an acyl-homoserine lactone (A...

Proximal tubule and loop of Henle function are coupled, with proximal transport determining loop fluid composition, and loop transport modulating glomerular filtration via tubuloglomerular feedback (TGF). To examine this interaction, we begin with published models of the superficial rat proximal convoluted tubule (PCT; including flow-dependent transport in a compliant tubule), and the rat thick...

We present work on a verse-composition assistant for composing, checking correctness of, and singing traditional Basque bertsoak—impromptu verses on particular themes. A performing bertsolari—a verse singer in the Basque Country—must adhere to strict rules that dictate the format and content of the verses sung. To help the aspiring bertsolari, we provide a tool that includes a web interface tha...

BCL11B/CTIP2 zinc-finger transcription factor is expressed in various types of cells in many different tissues. This study showed that BCL11B is expressed in the nucleus of the outer hair cells of the mouse cochlea, degeneration of which is known to cause deafness and presbycusis or age-related hearing loss (AHL). We tested whether or not Bcl11b heterozygosity would affect AHL in mice. Analysis...
