As the period length of this pacemaker is only approximately 24 hr, the circadian clock has to be reset every day by an input pathway in order to remain in resonance with geophysical time. This synchronization Division of Biochemistry Animal circadian rhythms appear to be generated by University of Fribourg feedback loops in gene expression that include both Rue du Musé e 5 transcriptional and ...
The circadian system regulates numerous physiological processes including immune responses. Here, we show that mice deficient of the circadian clock genes Cry1 and Cry2 [Cry double knockout (DKO)] develop an autoimmune phenotype including high serum IgG concentrations, serum antinuclear antibodies, and precipitation of IgG, IgM, and complement 3 in glomeruli and massive infiltration of leukocyt...
The interaction of Mtx toxins from Lysinibacillus sphaericus (formerly Bacillus sphaericus) with Bacillus thuringiensis subsp. israelensis Cry toxins and the influence of such interactions on Cry-resistance were evaluated in susceptible and Cry-resistant Culex quinquefasciatus larvae. Mtx-1 and Mtx-2 were observed to be active against both susceptible and resistant mosquitoes; however varying l...
A new approach has been proposed to design of an automatic infant cry recognition system based on the fuzzy transform (F-transform) that classifies two different kinds of cries, which come from physiological status and medical disease. Feature extraction and development of classification algorithms play an important role in the area of automatic analysis of infant cry signals. F-transform is th...
We have designed a high-throughput system for the identification of novel crystal protein genes (cry) from Bacillus thuringiensis strains. The system was developed with two goals: (i) to acquire the mixed plasmid-enriched genomic sequence of B. thuringiensis using next-generation sequencing biotechnology, and (ii) to identify cry genes with a computational pipeline (using BtToxin_scanner). In o...
Immunotherapy using T-cell epitope peptides or CpG DNA conjugated with allergenic protein is useful, although the mechanisms of these therapies differ. However, the combination of CpG DNA and peptide, but not protein, had not been documented. Therefore, we investigated CpG DNA conjugated with peptide to obtain positive synergistic effects. In the first experiment, mice were vaccinated with a co...
The circadian clock has a vital role in monarch butterfly (Danaus plexippus) migration by providing the timing component of time-compensated sun compass orientation, which contributes to navigation to the overwintering grounds. The location of circadian clock cells in monarch brain has been identified in the dorsolateral protocerebrum (pars lateralis); these cells express PERIOD, TIMELESS, and ...
The discovery and study of insecticidal bacteria, which began a little over a century ago, led to the development of commercial bacterial insecticides in the middle of the century that became the first successful and widely used microbial control agents. Most of these products were based on Bacillus thuringiensis, a bacterium that kills insects through the use of insecticidal proteins that subs...
BACKGROUND In nature, both daily light:dark cycles and temperature fluctuations are used by organisms to synchronize their endogenous time with the daily cycles of light and temperature. Proper synchronization is important for the overall fitness and wellbeing of animals and humans, and although we know a lot about light synchronization, this is not the case for temperature inputs to the circad...
In Bacillus subtilis, motility genes are expressed in a hierarchical pattern – governed by the σD transcription factor and other proteins such as EpsE molecular clutch SlrA/SlrR regulator proteins. contrast, motile species cereus group seem to express their non-hierarchical pattern, less is known about regulation, also given that no orthologs σD, EpsE, SlrA or SlrR found B. genomes. Here we sho...
