Histidine kinases are used extensively in prokaryotes to monitor and respond to changes in cellular and environmental conditions. In Bacillus subtilis, sporulation-specific gene expression is controlled by a histidine kinase phosphorelay that culminates in phosphorylation of the Spo0A transcription factor. Sda provides a developmental checkpoint by inhibiting this phosphorelay in response to DN...

The Shortened Dental Arch (SDA) concept introduced as early as 1981 by Kayser and was accepted by a great majority of dentists but not widely practiced. The SDA comprising anterior and premolar teeth in general fulfill the requirements of a functional dentition. Patients’ needs and demands vary much and should be individually assessed but the SDA concept deserves to be included in all treatment...

A novel method named as submicron-dot-array (SDA) doping is developed for the fabrication of low-temperature polycrystallinesilicon thin film transistors (TFTs). All electrical parameters are improved by employing SDA structure. It is worth mentioning that the mobility of fabricated device is 4 times of conventional TFTs. The proposed SDA method has great potential for system-onpanel applications.

There is a longstanding debate about the status of the principle Simplification of Disjunctive Antecedents (SDA), according to which a counterfactual with a syntactically disjunctive antecedent [(φ ∨ψ) > χ] entails a conjunction of counterfactuals [(φ > ψ)∧(ψ > χ)]. This principle is highly intuitive for most examples that have been considered, but it has also been claimed to be subject to empi...

AIM to study the activity of antioxidant enzymes and to evaluate an intensity of prooxidant processes in sarcoma 37 (S37) cells during tumor development and under influence of sodium dichloroacetate (SDA). METHODS Activity of total superoxide dismutase (SOD), SOD isoforms, catalase (Cat), glutathione peroxidase (GP), and glutathione reductase (GR), as well as content of reduced glutathione (G...

High-performance liquid chromatographic procedures with ultraviolet detection were developed for the quantitative determination of sulfadiazine (SDA) and trimethoprim (TMP) in swine tissues (kidney, liver, muscle, fat and fat + skin). In addition, high-performance liquid chromatography with atmospheric pressure chemical ionization mass spectrometry was used for the confirmation of the identity ...

We identified a signaling pathway that prevents initiation of sporulation in Bacillus subtilis when replication initiation is impaired. We isolated mutations that allow a replication initiation mutant (dnaA) to sporulate. These mutations affect a small open reading frame, sda, that was overexpressed in replication initiation mutants and appears to be directly regulated by DnaA. Mutations in rep...

We report here the characterization of slamdance (sda), a Drosophila melanogaster "bang-sensitive" (BS) paralytic mutant. This mutant exhibits hyperactive behavior and paralysis following a mechanical "bang" or electrical shock. Electrophysiological analyses have shown that this mutant is much more prone to seizure episodes than normal flies because it has a drastically lowered seizure threshol...

I our paper entitled “Optimized Fragmentation Regime for Diazirine Photo-Cross-Linked Peptides”, there are two separate textual errors, one in Figure 6B (and repeated in the TOC graphic) and one in the Data Analysis section. Results: Decision tree representation (Figure 6B and TOC graphic) In Figure 6B and again in the TOC graphic, a visual decision tree was created from the m/z binning in Figu...

The objective of this study was to determine the effect of antimicrobials on the survival and proliferation of Listeria monocytogenes in turkey breast rolls following electron-beam irradiation. Six antimicrobial additive treatments that include no preservatives (control), 0.1% potassium benzoate (PB), 2% sodium lactate (SL), 0.1% potassium benzoate plus 2% sodium lactate (PB + SL), 2% sodium la...
