The development of novel assays to detect collagen fragments is of utmost importance for diagnostic, prognostic and therapeutic decisions in various collagen-related diseases, and one essential question is to discover probe peptides that can specifically recognize target collagen sequences. Herein we have developed the fluorescence self-quenching assay as a convenient tool to screen the capability of a series of fluorescent probe peptides of variable lengths to bind with target collagen peptides. We have revealed that the targeting ability of probe peptides is length-dependent, and have discovered a relatively short probe peptide FAM-G(POG)8 capable to identify the target peptide...

The central amygdala is critical for the acquisition and expression of fear memories. This region receives a dense innervation from brainstem noradrenergic cell groups and has a high level of α2-adrenoceptor expression. Using whole-cell electrophysiological recordings from rat brain slices, we characterise the role of pre-synaptic α2-adrenoceptor in modulating discrete inhibitory and excitatory connections within both the lateral and medial division of the central amygdala. The selective α2-adrenoceptor agonist clonidine blocked the excitatory input from the pontine parabrachial neurons onto neurons of the lateral central amygdala...

In this paper, Bio-MOF-1 is prepared as reported and then Eu(3+) is introduced into it via cation exchange method. A FAM-labeled ssDNA is chosen to fabricate with the obtained Eu(3+)@Bio-MOF-1. A luminescent hybrid material is assembled, which can exhibit the fluorescence of Eu(3+) and FAM simultaneously by adjusting the ratio of FAM-ssDNA and Eu(3+)@Bio-MOF-1. The sample is then used for the detecting of metal ions, results shows which has good selectively for Cu(2+) (LOD = 0.14 μM, 0-250 μM). The introduction of Cu(2+) can quench the fluorescence of FAM while the luminescent intensity of Eu(3+) enhancing...

The β-secretase (BACE1) initiates the generation of toxic amyloid-β peptide (Aβ) from amyloid-β precursor protein (APP), which was widely considered to play a key role in the pathogenesis of Alzheimer's disease (AD). Here, a novel microfluidics-based mobility shift assay (MMSA) was developed, validated, and applied for the screening of BACE1 inhibitors for AD. First, the BACE1 activity assay was established with a new fluorescent peptide substrate (FAM-EVNLDAEF) derived from the Swedish mutant APP, and high-quality ratiometric data were generated in both endpoint and kinetic modes by electrophoretic separation of peptide substrate from the BACE1 cleaved product (FAM-EVNL) before fluorescence quantification...

Doxorubicin (DOX), an anthracycline-based antibiotic, is regularly used in the management of carcinomas, and haematological malignancies have been downplayed in chemotherapy because of its ability to induce dilated cardiomyopathy (DCM). Dexrazoxane is approved to combat the cardiotoxicity, but limited by its adverse effects. Redox imbalance and reactive oxygen species generation plays major role in DOX-induced cardiotoxicity. Histamine, known to mediate various cardiovascular effects, but nevertheless the role of histamine or its receptors in DOX-induced DCM is remained obscure...

The genus Halothiobacillus contains four species of obligate autotrophs with validly published names, of which Halothiobacillus halophilus and Halothiobacillus hydrothermalis are very distant from the type species - on the basis of the 16S rRNA gene, they have 90.7 % and 90.9 % identity to that of the type species, Halothiobacillus neapolitanus. As these values fall below the Yarza cut-off for the rank of genus, and these two species also show no clear affiliation to the closely related genus Thioalkalibacter, a polyphasic study was undertaken to determine if they represent a separate genus...

BACKGROUND: The aim of this study was to estimate variance components and to identify genomic regions and pathways associated with resistance to gastrointestinal parasites, particularly Haemonchus contortus, in a breed of sheep adapted to tropical climate. Phenotypes evaluations were performed to verify resistance to gastrointestinal parasites, and were divided into two categories: i) farm phenotypes, assessing body condition score (BCS), degree of anemia assessed by the famacha chart (FAM), fur score (FS) and feces consistency (FC); and ii) lab phenotypes, comprising blood analyses for hematocrit (HCT), white blood cell count (WBC), red blood cell count (RBC), hemoglobin (HGB), platelets (PLT) and transformed (log10) egg per gram of feces (EPGlog)...

Collagen, the major structural component of nearly all mammalian tissues, undergoes extensive proteolytic remodeling during developmental states and a variety of life-threatening diseases such as cancer, myocardial infarction, and fibrosis. While degraded collagen could be an important marker of tissue damage, it is difficult to detect and target using conventional tools. Here, we show that a designed peptide (collagen hybridizing peptide: CHP), which specifically hybridizes to the degraded, unfolded collagen chains, can be used to image degraded collagen and inform tissue remodeling activity in various tissues: labeled with 5-carboxyfluorescein and biotin, CHPs enabled direct localization and quantification of collagen degradation in isolated tissues within pathologic states ranging from osteoarthritis and myocardial infarction to glomerulonephritis and pulmonary fibrosis, as well as in normal tissues during developmental programs associated with embryonic bone formation and skin aging...

A novel Gram-stain-negative, chemolithoautotrophic sulfur oxidizer, strain JG42T, was isolated from a hot spring microbial mat. As an electron donor for autotrophic growth, strain JG42T utilized sulfide, thiosulfate, tetrathionate and elemental sulfur. Cells of strain JG42T were oxidase-positive and catalase-negative. The G+C content of the genomic DNA was 65 mol%. The predominant cellular fatty acid was C16 : 0. Phylogenetic analysis of the 16S rRNA gene indicated that strain JG42T belonged to the order Chromatiales, but sequence similarities to the known species were less than 94 %...

Several strictly anaerobic bacteria that are Gram-stain-positive have the ability to use uric acid as the sole source of carbon and energy. The phylogeny of three such species, Clostridium acidurici, Clostridium purinilyticum, and Eubacterium angustum, members of the Clostridium cluster XII that ferment purines, but not most amino acids or carbohydrates, has been re-examined, taking advantage of their recently sequenced genomes. Phylogenetic analyses, based on 16S rRNA gene sequences, protein sequences of RpoB and GyrB, and on a concatenated alignment of 50 ribosomal proteins, revealed tight clustering of C...
