BACKGROUND: Bisphenol F (BPF) and bisphenol S (BPS) are increasingly used as alternatives to endocrine disrupting chemical bisphenol A (BPA). Evidence from in vitro and animal studies demonstrates that BPA, BPF and BPS induce oxidative stress, a proposed mechanism that is relevant to various adverse health effects. Evaluation in humans is hampered by the potentially high within-subject variability of urinary measurements. OBJECTIVE: To evaluate the variability and associations of levels of BPA, BPS, BPF and 3 oxidative stress markers [i...

In Liberibacter asiaticus , PrbP is an important transcriptional accessory protein that regulates gene expression through interactions with the RNA polymerase β-subunit and a specific sequence on the promoter region. The constitutive expression of prbP observed upon chemical inactivation of PrbP/DNA interactions in vivo indicated that the expression of prbP was not auto-regulated at the level of transcription. This observation suggested that a modulatory mechanism via protein-protein interactions maybe involved...

Commonly used image fusion techniques generally produce good results for images obtained from the same sensor, with a standard ratio of spatial resolution (1:4). However, an atypical high ratio of resolution reduces the effectiveness of fusion methods resulting in a decrease in the spectral or spatial quality of the sharpened image. An important issue is the development of a method that allows for maintaining simultaneous high spatial and spectral quality. The authors propose to strengthen the pan-sharpening methods through prior modification of the panchromatic image...

Abnormalities in social behavior are a co-morbid symptom of idiopathic generalized epilepsies such as childhood absence epilepsy. The Genetic Absence Epilepsy Rats from Strasbourg (GAERS) model is a spontaneously occurring absence epilepsy phenotype closely correlated to that of human absence epilepsies. Similar to the human conditions, GAERS display social abnormalities. Previous studies have only demonstrated social abnormalities in female GAERS, whereas social problems are observed in male and female patients...

The emergence of microbial antibiotic resistance is a global health threat. In clinical settings, the key to controlling spread of resistant strains is accurate and rapid detection. As traditional culture-based methods are time consuming, genetic approaches have recently been developed for this task. The detection of antibiotic resistance is typically made by measuring a few known determinants previously identified from genome sequencing, and thus requires the prior knowledge of its biological mechanisms. To overcome this limitation, we employed machine learning models to predict resistance to 11 compounds across four classes of antibiotics from existing and novel whole genome sequences of 1936 E...
