A new double-seeded insert (DSI) technique is described for culture of branchial epithelial preparations from freshwater rainbow trout on filter supports. DSI epithelia contain both pavement cells and mitochondria-rich (MR) cells (15.7+/-2.5 % of total cell numbers). MR cells occur singly or in clusters, are voluminous, open apically to the 'external environment' and exhibit ultrastructural cha...

Biological uptake of dissolved silicate (DSi) and formation of biogenic silica (BSi) during diatom growth modifies the form of Si carried from the continents to the world ocean. Significant concentrations of BSi, averaging 28.0 pmol L-l, are found in all sizes of rivers. The global contribution of BSi carried by rivers was estimated as 1.05 ? 0.20 Tmol Si year’. Combined with the global mean ri...

Colposcopy with biopsy is pivotal to cervical cancer prevention programs as it is called to identify the precancerous lesions on patients that screen positive. We present a cervical cancer case from IMPROVE-COLPO, a postmarketing, multicenter, two-arm observational study on US community colposcopy that collects outcomes with the adjunctive Dynamic Spectral Imaging (DSI) in its prospective arm. ...

In a recent functional magnetic resonance imaging study, a complex neural circuit was shown to be involved in human males during sexual arousal [A. Ferretti et al. (2005) Neuroimage, 26, 1086]. At group level, there was a specific correlation between penile erection and activations in anterior cingulate, insula, amygdala, hypothalamus and secondary somatosensory regions. However, it is well kno...

The present acoustic analysis of the voice is based on the data obtained from 54 singing children (19 boys and 25 girls). They were divided into two groups of 27 subjects each, with one including premutational-age the other mutational-age children (from 8 to 12 and from 13 to 16 years respectively). <> software package was used to analyse phonetograms and spectro...

Recurrent excitation is believed to underlie persistent neural activity observed in the prefrontal cortex and elsewhere during working memory. However, other positive and negative feedback mechanisms, operating on disparate timescales, may also play significant roles in determining the behavior of a working memory circuit. In this study, we examined dynamical interactions of multiple feedback m...

– The dynamic and kinetic behavior of processes occurring in fractals with spatial discrete scale invariance (DSI) is considered. Spatial DSI implies the existence of a fundamental scaling ratio (b1). We address time-dependent physical processes, which as a consequence of the time evolution develop a characteristic length of the form ξ ∝ t, where z is the dynamic exponent. So, we conjecture tha...

The dynamic strength index (DSI) is a useful tool to assess an athlete's capacity effectively use maximum during tasks. Although DSI traditionally calculated based on peak forces, the ability express force over time (i.e., impulse) better predictor of performance. purpose this study was investigate association between (fDSI) and impulse (iDSI). Nineteen female collegiate lacrosse players perfor...

In spite of the many developments in synthetic oligonucleotide (ON) chemistry and design, invasion into double-stranded DNA (DSI) under physiological salt and pH conditions remains a challenge. In this work, we provide a new ON tool based on locked nucleic acids (LNAs), designed for strand invasion into duplex DNA (DSI). We thus report on the development of a clamp type of LNA ON-bisLNA-with ca...

The first aim of the present study was to investigate the applicability of the two-factor structure (perceptual-motor skills by 11 items, e.g., "fluent driving"; safety skills by 9 items, e.g., "conforming to the speed limits") of the Driver Skill Inventory (DSI) among British, Dutch, Finnish, Greek, Iranian, and Turkish drivers. It was also hypothesized that the combination of self reported hi...
