PA1 01 Do biochemical and geochemical influences of acidic deposition affect dendroclimatic stability? PA2 Reconstruction of past climate variations: a challenge for the present and future PA2 10 Dendrochronological analysis of selected spruce stands in the Drahany highlands PA2 14 Studies with the Finnish over 7650-year pine chronology PA3 Tree rings and insects, diseases and anthropogenic fac...
Pardaxins are a class of ichthyotoxic peptides isolated from fish mucous glands. Pardaxins physically interact with cell membranes by forming pores or voltage-gated ion channels that disrupt cellular functions. Here we report the high-resolution structure of synthetic pardaxin Pa4 in sodium dodecylphosphocholine micelles, as determined by (1)H solution NMR spectroscopy. The peptide adopts a ben...
Background: Anthrax is a particularly dangerous infectious disease that affects humans and livestock. Efficacious vaccines that can rapidly induce a long-term immune response are required to prevent anthrax infection in humans. Domains 4 and 1 of the protective antigen (PA) and lethal factor (LF), respectively, have very high antigenic properties. Aims: In this...
Polyamide4 (PA4) is a bioplastic with superior properties and high biodegradability. Although some PA4-degrading microorganisms have been isolated from various environments, enzymes that play role in PA4 degradation are yet to be identified. In this study, we novel microorganism, Pseudoxanthomonas sp. TN-N1. This strain showed clear zone surrounding the colony on an agar plate medium containing...
MicroRNAs (miRNAs) are involved in plant growth, development, and response to biotic and abiotic stresses. Most of the miRNAs that have been identified in model plants are well characterized, but till now, no reports have previously been published concerning miRNAs in Paulownia australis. In order to investigate miRNA-guided transcript target regulation in P. australis, small RNA libraries from...
Peptide amphiphiles (PAs) are promising tools for the intracellular delivery of numerous drugs. PAs are known to be biodegradable systems. Here, four PA derivatives containing arginine and lysine conjugated with fatty acyl groups with different chain lengths, namely, PA1: R-K(C14)-R, PA2: R-K(C16)-R, PA3: K(C14)-R-K(C14), and PA4: K(C16)-R-K(C16), where C16 = palmitic acid and C14 = myristic ac...
We propose two novel extensions to the Match-LSTM Boundary model for question answering on the SQuAD dataset. First we propose doing attention in the passage and question encoders. Second we propose adding a one-way conditional dependency between start-of-span and end-of-span prediction. In our evaluations, we show that these extensions result in a model that outperforms our implementation of v...
In this study, matrix-type transdermal patches containing diclofenac diethylamine were prepared using different ratios of polyvinylpyrrolidone (PVP) and ethylcellulose (EC) by solvent evaporation technique. The drug matrix film of PVP and EC was casted on a polyvinylalcohol backing membrane. All the prepared formulations were subjected to physical studies (moisture content, moisture uptake, and...
Pantoea ananatis is an emerging phytopathogen that infects a broad spectrum of plant hosts. Here, we present the genomes of two South African isolates, P. ananatis PA4, which causes center rot of onion, and BD442, isolated from brown stalk rot of maize.
