Chameleon sequences reveal structural effects in proteins representing micelle‐like distribution of hydrophobicity

FEBS Open Bio, EarlyView.
Amino acids sequence of two different proteins with the same sequence (chameleon sequence—black boxes) represent in 3D structure of the proteins different secondary structures: HHHH—helical and BBB—Beta‐structural. The chains folded in water environment adopt different III‐order structures in which the chameleon fragments appear to adopt similar status

Exon 7 splicing of ERα predicts poor prognosis and increases phenotypic heterogeneity in luminal a subtype breast cancer

FEBS Open Bio, EarlyView.
ERα splice variant ERα∆7 lacks the C‐terminus, and its expression may change phenotypes of breast cancers. Our results showed that ERα∆7 is found in the luminal A subtype, and elevated ERα∆7 levels are linked to improved cell survival with lower proliferation and migration.

Analysing the significance of small conformational changes and low occupancy states in serial crystallographic data

FEBS Open Bio, EarlyView.
This protocol paper outlines methods to establish the success of a time‐resolved serial crystallographic experiment, by means of statistical analysis of timepoint data in reciprocal space and models in real space. We show how to amplify the signal from excited states to visualise structural changes in successful experiments.

Detection of Event Related Potentials

International Journal of Neuroscience, 1989
A statistical approach is presented which provides efficient procedures to detect both Event Related Potential (ERP) and its spectral structure. Situations where undesirable signal or "artifact" is present, are considered. In these cases, a "noise" sample can be used which complements the insufficient knowledge given for the sample where we expect to ...

Event-Related Potentials

Journal of Clinical Neurophysiology, 1992
Event-related potentials (ERPs) are scalp recorded electrophysiological responses that are related to an internal cognitive event. This review summarizes recent findings on the effects of neurologic disease and the origin of ERPs obtained in expectancy, attention, memory, and linguistic tasks.

Event rate and event‐related potentials in ADHD

Journal of Child Psychology and Psychiatry, 2006
Background:  It has been repeatedly found that performance of children with attention deficit hyperactivity disorder (ADHD) is more impaired when a long inter‐stimulus interval (ISI) is used than when a short ISI is used.

Event-related potentials in schizophrenics

Electroencephalography and Clinical Neurophysiology, 1980
Fifteen schizophrenics and 15 age-matched controls were compared on 3 auditory event-related potential (ERP) paradigms that elicited a variety of components. In one paradigm, tones were given at 0.75, 2.25 and 6.75 sec interstimulus intervals; in another, infrequently occurring targets in a reaction-time task were interspersed with frequent background ...

Event-Related Potentials in Hypertriglyceridemia

International Journal of Neuroscience, 1995
Event-related potentials (ERPs) of twenty-three hypertriglyceridemic (HTG) patients and twenty-three age-matched healthy controls were recorded in two different experimental conditions that the target stimulus was counted (Test 1) or uncounted (Test 2). Latencies of each wave were inside normal limits in all patients.

Event-Related Potentials in Psychiatry

Clinical EEG and Neuroscience, 2007
Electrophysiological assessments of psychiatric disorders have produced a number of promising, highly replicable findings and thus carry the potential of becoming clinically utilizable in the diagnostic or prognostic evaluation of psychopathological conditions.

A `passive' event-related potential?

International Journal of Psychophysiology, 1998
Event potentials (ERPs) were recorded in response to visual patterns in two conditions: (1) where no instructions were given to subjects; and (2) where subjects pressed a button whenever a rare stimulus was detected. P3 amplitudes for the No Instructions condition were smaller than for the Active condition, but the latency of the P3s did not differ ...
