Axonal projections originating from the mammillary bodies represent important pathways that are essential for spatial information processing. Mammillothalamic tract is one of the main efferent projection systems of the mammillary body belonging to the limbic "Papez circuit". This study was aimed to... | PMID: 19026995

Lampreys are one of the most basal animals in which many of the true vertebrate characteristics (e.g., neural crest, placodes, segmented brain, skull, paired sensory organs, pharyngeal skeleton) are present. Studying the molecular and developmental mechanisms responsible for the formation of these s... | PMID: 20147019

We report here that sodium hydrosulfide (NaHS), an H(2)S donor, concentration-dependently suppressed rotenone-induced cellular injury and apoptotic cell death. NaHS also prevented rotenone-induced p38- and c-Jun NH(2)-terminal kinase (JNK)-mitogen-activated protein kinase (MAPK) phosphorylation and... | PMID: 18832435

Boar sperm functions, lipid peroxidation status, mitochondrial membrane potential (DeltaPsi(m)) and membrane permeability (apoptosis like features) were assessed during liquid preservation. Four ejaculates each from four Hampshire boars were extended with Beltsville Thawing Solution and preserved at... | PMID: 18295985

We synthesized a series of new PPCys that differ only in the heterocyclic peripheral groups of the chromophore. With this strategy, the absorption spectra can be tuned between 684 and 864 nm, while high fluorescence quantum yields are maintained. The influence of the heterocycle on the optical prope... | PMID: 19296481

We include a demonstration of global gene expression analysis using a comprehensive zebrafish-specific oligonucleotide microarray platform. The zebrafish expression microarray platform contains 385,000 probes, 60 base pairs in length, interrogating 37,157 targets with up to 12 probes per target. For... | PMID: 19684566

The effects of hydrophobic thickness and the molar phosphatidylglycerol (PG) content of lipid bilayers on the structure and membrane interaction of three cationic antimicrobial peptides were examined: aurein 2.2, aurein 2.3 (almost identical to aurein 2.2, except for a point mutation at residue 13),... | PMID: 19167304

We show significant differences in the glycosylation patterns of two SIV strains widely used in animal models of HIV disease and vaccine studies. We also demonstrate the modification of a host protein important in HIV biology (HLA-DR) by O-GlcNAc. Further, this experimental pipeline allows for the i... | PMID: 19072736

Human phospholipid scramblase 1 (hPLSCR1) scrambles plasma membrane phospholipids during cell activation, blood coagulation and apoptosis. It was over-expressed in E. coli with a histidine tag and purified from the inclusion bodies (*30 mg/l culture broth) under denaturing conditions using 8 M urea.... | PMID: 18629440

The synthesis of triple-helix-forming oligonucleotides (TFOs) linked to a series of cyanine monomethines has been performed. Eight cyanines including one thiocyanine, four thiazole orange analogues, and three quinocyanines were attached to the 5'-end of 10-mer pyrimidine TFOs. The binding properties... | PMID: 19005602

We describe the contributions of fluorescent probes to far-field super-resolution imaging, focusing on fluorescent proteins and organic small-molecule fluorophores. We describe the features of existing super-resolution fluorophores and highlight areas of importance for future research and developmen... | PMID: 19002208

We propose to identify DIGE DE proteins using a two-stage linear mixed model. The proposal consists of splitting the overall model for the measured intensity into two interconnected models. First, we fit a normalization model that accounts for the general experimental effects, such as gel and CyDye... | PMID: 18818217

A facile synthetic route to prepare monofunctional carbocyanine dyes for biological application is developed. Three pentamethine carbocyanine dyes have been successfully modified with a variety of functional groups such as: carboxylic acids, azides, or alkynes. The new dyes are characterized by stro... | PMID: 19053316

We demonstrate that commercially available standard fluorescent probes, i.e. Alexa 647 labeled antibodies, can be used as efficient photoswitches. In combination with localization microscopy approaches the method is ideally suited to study the spatial organization of proteins in sub-cellular structu... | PMID: 18790061

We used single-molecule fluorescence resonance energy transfer to probe the interactions between RT and nucleic acid substrates in real time. RT was observed to slide on nucleic acid duplexes, rapidly shuttling between opposite termini of the duplex. Upon reaching the DNA 3' terminus, RT can spontan... | PMID: 19008444

Structural and vibrational properties of mono- and multichromophoric hemicyanine (HC) dyes in solution and adsorbed on silver-coated films have been investigated using optical absorption and resonance Raman scattering techniques, with interpretations aided by theoretical calculations. This is the fi... | PMID: 19045418

We ablated the sheath glial cell of the major sensory organ of Caenorhabditis elegans. We found that glia-ablated animals exhibit profound sensory deficits and that glia provide activities that affect neuronal morphology, behavior generation, and neuronal uptake of lipophilic dyes. To understand the... | PMID: 18974354

There were 16 upregulated genes in the early phase group, 56 genes in the midphase group, and 17 genes in the continuous group. Functional categorization revealed dominantly upregulated gene categories in each group; transcription/translation in the early phase group, enzyme/metabolism in the midpha... | PMID: 18978588

We report that SG formation negatively regulates the SAPK apoptotic response, and that the signalling scaffold protein RACK1 functions as a mediator between the two responses. RACK1 binds to the stress-responsive MTK1 MAPKKK and facilitates its activation by type 2 stress; however, under conditions... | PMID: 18836437
