background: airport workers are continuously exposed to different levels of radiofrequency microwave (rf/mw) radiation emitted by radar equipments. radars are extensively used in military and aviation industries. over the past several years, our lab has focused on the health effects of exposure to different sources of electromagnetic fields such as cellular phones, mobile base stations, mobile ...

As part of the certification campaign of three candidate reference materials for the determination of aflatoxin M1 (AfM1) in whole milk powders, homogeneity, short- and long-term stability tests of naturally contaminated milk powders have been performed. The homogeneity of two AfM1-contaminated milk powders was studied by taking samples at regular intervals of the filling sequences and analysin...

In the steady-state an organism maintains a dynamic balance between the dietary intake and metabolism of each of the primary nutrients, carbohydrate (CHO), fat and protein. However, such a steady-state, while generally true in adults in the long term, is never achieved during short periods (i.e. within 1 d) because of the discontinuous nature of food intake. The fact that we consume our food as...

This opinion article argues that noise (randomness) in neural activity is the limiting factor in visual working memory (WM), determining how accurately we can maintain stable internal representations of external stimuli. Sharing of a fixed amount of neural activity between items in memory explains why WM can be successfully described as a continuous resource. This contrasts with the popular con...

Listeners with normal hearing show considerable individual differences in speech understanding when competing speakers are present, as in a crowded restaurant. Here, we show that one source of this variance are individual differences in the ability to focus selective attention on a target stimulus in the presence of distractors. In 50 young normal-hearing listeners, the performance in tasks mea...

in this study, the effect of green tea extract was studied on quality of surimi produced from fish silver carp during refrigerated storage. surimi was prepared and immersed with various concentrations of tea extracts (0, 2 and 4%). samples were refrigerated for 15 days and were performed chemical tests include ph, total volatile bases nitrogen (tvb-n), thiobarbitoric acid (tba) test and total b...

Storage conditions are considered to be a critical component of DNA-based microbial community analysis methods. However, whether differences in short-term sample storage conditions impact the assessment of bacterial community composition and diversity requires systematic and quantitative assessment. Therefore, we used barcoded pyrosequencing of bacterial 16S rRNA genes to survey communities, ha...

The segregation of brain fiber tractography data into distinct and anatomically meaningful clusters can help to comprehend the complex brain structure and early investigation and management of various neural disorders. We propose a novel stacked bidirectional long short-term memory(LSTM) based segmentation network, (BrainSegNet) for human brain fiber tractography data classification. We perform...
