We have examined the S1 nuclease sensitivity in the promoter of both the chicken and mouse alpha 2(I) collagen genes. When these DNAs are introduced into supercoiled plasmids and digested with S1 nuclease, a discrete region containing one or more cleavages is found in each promoter. These S1 cleavage sites were mapped by the distance of the S1 site from known restriction enzyme cleavage sites. ...
Selecting an appropriate matrix solution is one of the most effective means of increasing the ionization efficiency of phosphopeptides in matrix-assisted laser-desorption/ionization time-of-flight mass spectrometry (MALDI-TOF-MS). In this study, we systematically assessed matrix combinations of 2, 6-dihydroxyacetophenone (DHAP) and diammonium hydrogen citrate (DAHC), and demonstrated that the l...
Cone snails (Conus) are predatory marine mollusks that immobilize prey with venom containing 50-200 neurotoxic polypeptides. Most of these polypeptides are small disulfide-rich conotoxins that can be classified into families according to their respective ion-channel targets and patterns of cysteine-cysteine disulfides. Conkunitzin-S1, a potassium-channel pore-blocking toxin isolated from C. str...
Metal-enhanced fluorescence (MEF) and delayed fluorescence (alpha α-S1) studies of acriflavin have been undertaken using steady-state and time-resolved fluorescence measurements on silver island films (SiFs) supporting a thin poly(vinyl alcohol) (PVA) polymer film. Nearly a 3.5-fold enhancement in the far-field fluorescence intensity of acriflavin is observed coupled with a decrease in decay ti...
The relationship between gap junctional intercellular communication (GJIC) and mammary cell (CID-9) differentiation in vitro was explored. CID-9 cells differentiate and express beta-casein in an extracellular matrix (ECM)- and hormone-dependent manner. In response to interaction with the ECM, cells in culture modulated the expression of their gap junction proteins at the transcriptional and pos...
In interphase cells, alpha-casein kinase I (alpha-CKI) is found associated with cytosolic vesicular structures, the centrosome, and within the nucleus. To identify the specific vesicular structures with which alpha-CKI is associated, established cell lines and primary rat neurons were immunofluorescently labeled with an antibody raised to alpha-CKI. In nonneuronal cells, alpha-CKI colocalizes w...
In dairy industry there has always been great concern about the microbial and protein quality of liquid milk fractions obtained by microfiltration (MF). The objectives research were to study impact MF on evolution microfiltered (MFM), micellar casein concentrates (LMCC) serum permeates (SP) during storage at 4 °C. This was carried out with three different batches using diafiltration. Samples ch...
To explore the role of oscillatory dynamics of the somatosensory thalamocortical network in perception and decision making, we recorded the simultaneous neuronal activity in the ventral posterolateral nucleus (VPL) of the somatosensory thalamus and primary somatosensory cortex (S1) in two macaque monkeys performing a vibrotactile detection task. Actively detecting a vibrotactile stimulus and re...
