Ultimobranchial body and parathyroid glands of the freshwater snake Natrix piscator in response to vitamin D3 administration.

Vitamin D3 (20 I.U./100 g body wt) was administered to the freshwater snake Natrix piscator for 15 days. Elevation of serum calcium and inorganic phosphate levels was observed after the treatment. The ultimobranchial body became active whereas the parathyroid glands exhibited reduced activity.

Interaction of Catechu Dye with DNA: Spectroscopic and In Silico Approach

Catechin, a yellow colored molecule obtained from the wood of Acacia catechu was analyzed for its interaction with synthetic DNA duplexes using spectroscopic analysis. UV-Visible spectroscopic analysis revealed the non-intercalative binding mode. Fourier Transform Infrared spectroscopy (FTIR) analysis expose chemical shift indicated by various vibrational stretches and an increase in the intensity of base stacking was observed by Circular Dichroism (CD), respectively. This inference was further confirmed through nuclear staining technique and also in electrophoretic technique; the dye quenches the fluorescent intensity of ethidium bromide. The result of fluorescence spectroscopy was in concordance with the electrophoretic technique. In addition, the spectroscopic results were in accordance with the molecular docking studies of specific catechin compound from the catechu dye with CT-DNA. This kind of site specificity is a gain in the medicinal field as the drug can be DNA targeted for cancer therapeutics. The present work reveals that catechu dye has a noteworthy application in the field of medical bioscience.     

Hit-to-lead optimization of disubstituted oxadiazoles and tetrazoles as mGluR5 NAMs

Here we report the discovery and early SAR of a series of mGluR5 negative allosteric modulators (NAMs). Starting from a moderately active HTS hit we synthesized 3,5-disubstituted-oxadiazoles and tetrazoles as mGluR5 NAMs. Based on the analysis of ligand efficiency and lipophilic efficiency metrics we identified a promising lead candidate as a starting point for further optimization.     

Complete genome sequence of Sphaerobacter thermophilus type strain (S 6022)

Sphaerobacter thermophilus Demharter et al. 1989 is the sole and type species of the genus Sphaerobacter, which is the type genus of the family Sphaerobacteraceae, the order Sphaerobacterales and the subclass Sphaerobacteridae. Phylogenetically, it belongs to the genomically little studied class of the Thermomicrobia in the bacterial phylum Chloroflexi. Here, the genome of strain S 6022(T) is described which is an obligate aerobe that was originally isolated from an aerated laboratory-scale fermentor that was pulse fed with municipal sewage sludge. We describe the features of this organism, together with the complete genome and annotation. This is the first complete genome sequence of the thermomicrobial subclass Sphaerobacteridae, and the second sequence from the chloroflexal class Thermomicrobia. The 3,993,764 bp genome with its 3,525 protein-coding and 57 RNA genes is a part of the Genomic Encyclopedia of Bacteria and Archaea project.     

Complete genome sequence of Vulcanisaeta distributa type strain (IC-017)

Vulcanisaeta distributa Itoh et al. 2002 belongs to the family Thermoproteaceae in the phylum Crenarchaeota. The genus Vulcanisaeta is characterized by a global distribution in hot and acidic springs. This is the first genome sequence from a member of the genus Vulcanisaeta and seventh genome sequence in the family Thermoproteaceae. The 2,374,137 bp long genome with its 2,544 protein-coding and 49 RNA genes is a part of the Genomic Encyclopedia of Bacteriaand Archaea project.     

Non-contiguous finished genome sequence of the opportunistic oral pathogen Prevotella multisaccharivorax type strain (PPPA20)

Prevotella multisaccharivorax Sakamoto et al. 2005 is a species of the large genus Prevotella, which belongs to the family Prevotellaceae. The species is of medical interest because its members are able to cause diseases in the human oral cavity such as periodontitis, root caries and others. Although 77 Prevotella genomes have already been sequenced or are targeted for sequencing, this is only the second completed genome sequence of a type strain of a species within the genus Prevotella to be published. The 3,388,644 bp long genome is assembled in three non-contiguous contigs, harbors 2,876 protein-coding and 75 RNA genes and is a part of the Genomic Encyclopedia of Bacteria and Archaea project.
