The recent discovery of genomic 5-hydroxymethylcytosine (hmC) and mutations affecting the respective Tet hydroxylases in leukemia raises fundamental questions about this epigenetic modification. We present a sensitive method for fast quantification of genomic hmC based on specific transfer of radiolabeled glucose to hmC by a purified glucosyltransferase. We determined hmC levels in various adul...

Despite a relatively short history, the modern-day study of communication has grown into multiple subfields. To better understand relationship between Human-Machine Communication (HMC) research and traditional science, this examines published scholarship in 28 communication-specific journals from 2011–2021 focused on human-machine (HMC). Findings suggest limited prior emphasis HMC within review...

Mast cells play an important role in a variety of inflammatory diseases, particularly asthma and atopy. Peroxisome proliferator-activated receptor gamma (PPARγ) is a member of the large nuclear hormone receptor transcription factor superfamily, and has been recently implicated in the anti-inflammatory response. To investigate a possible role for PPARγ in human mast cells, we studied the effects...

The ten-eleven-translocation 5-methylcytosine dioxygenase (TET) family of enzymes catalyzes the conversion of 5-methylcytosine (5-mC) to 5-hydroxymethylcytosine (5-hmC), a modified cytosine base that facilitates gene expression. Cells respond to hypoxia by inducing a transcriptional program regulated in part by oxygen-dependent dioxygenases that require Fe(II) and α-ketoglutarate. Given that th...

MOTIVATION The two major epigenetic modifications of cytosines, 5-methylcytosine (5-mC) and 5-hydroxymethylcytosine (5-hmC), coexist with each other in a range of mammalian cell populations. Increasing evidence points to important roles of 5-hmC in demethylation of 5-mC and epigenomic regulation in development. Recently developed experimental methods allow direct single-base profiling of either...

Rice kernel dimensions affect the performance of various post-harvest processes. This study assessed variability trends in kernel dimensional distributions of Bengal (medium-grain), Cypress, and Drew (long-grains) rice varieties. Rice was harvested at various stages of maturity from Stuttgart and Keiser, Arkansas during the autumns of 1998, 1999, and 2000. Brown rice kernel dimensions decreased...

Ten-eleven translocation (TET) enzymes catalyze the oxidation of 5-methylcytosine (5-mC) to 5-hydroxymethylcytosine (5-hmC) and then to 5-formylcytosine (5-fC) and 5-carboxylcytosine (5-caC), resulting in genomic DNA demethylation. Decreased 5-hmC levels have been reported in a variety of cancers, and loss of 5-hmC might be considered an epigenetic hallmark of cancer. However, the prognostic va...

The hybrid Monte Carlo (HMC) algorithm is applied for the Bayesian inference of the stochastic volatility (SV) model. We use the HMC algorithm for the Markov chain Monte Carlo updates of volatility variables of the SV model. First we compute parameters of the SV model by using the artificial financial data and compare the results from the HMC algorithm with those from the Metropolis algorithm. ...

We established an autologous specific T-cell killer clone, TcHMC-1, that has been cultured and has retained its function for over 1 year. TcHMC-1 and target cells (HMC-1-8) were derived from the metastatic pleural effusion of a patient with mammary carcinoma. At culture initiation, pleural exudative lymphocytes (PLEL) already demonstrated a high cytotoxic activity against uncloned HMC-1 breast ...

The mechanisms by which anti-DNA antibodies contribute to the pathogenesis of lupus nephritis (LN) remain to be elucidated. This study investigates the binding of polyclonal anti-DNA immunoglobulins from patients with systemic lupus erythematosus (SLE) to human mesangial cells (HMC) in vitro. Testing of cross-sectional serum samples from 280 LN patients (108 during active disease; 172 during re...
