In this paper, we evaluate the correlation estimate, based on multiple window spectrum analysis, between the respiratory center frequency and the high-frequency band of the heart- rate variability (HRV) power. One aim is to examine whether a more restricted frequency range would better capture respiratory related HR variation, especially when the HR variation is changing rapidly. The respiratory p

Abstract Objective. Solid pseudopapillary neoplasm (SPN) of the pancreas is a rare clinical entity. The objective of this study was to review a single institution's experience with this uncommon tumor, as well as review the literature. Material and Methods. Consecutive patients, who underwent surgery for a pathologically confirmed SPN between 1991 and 2010, were retrospectively reviewed. A PubMed

Background: There is a circadian and circaseptal (weekly) variation in the onset of acute coronary syndrome (ACS). The aim of this study was to elucidate whether the likelihood of ACS among emergency department (ED) chest pain patients varies with the time of presentation. Methods: All patients presenting to the Lund ED at Skåne University Hospital with chest pain or discomfort during 2006 and 20

Purpose: Resident microglial cells normally do not express sialoadhesin (a sialic acid binding receptor), whereas recruited inflammatory macrophages have been shown to do so. The expression of sialoadhesin was examined here in the course of photoreceptor cell degeneration and following transplantation. Methods: Sialoadhesin expression was analyzed in retinas of rd1 and rds mice. For transplantatio

In this paper, we suggest that the properties of Swedish present participles can be accounted for if we take a syntactic approach to lexical categories in the lines of Distributed Morphology. We depart from the fact that Swedish words ending in -ande/-ende have the same denotation whether they appear attributively, predicatively, or nominally. Syntactically however, -ande/-ende-derivations appear

INTRODUCTION: Calcitonin gene-related peptide (CGRP) is a neuronal messenger in intracranial sensory nerves and is considered to play a significant role in migraine pathophysiology. MATERIALS AND METHODS: We investigated the effect of the CGRP receptor antagonist, telcagepant, on CGRP-induced cranial vasodilatation in human isolated cerebral and middle meningeal arteries. We also studied the expre

Aims: The aim of this study was to find variables related to positive attitudes to physical education (PE) and strong sense of coherence (SOC) among adolescents. Methods: The study included three parts: seven physical tests; a questionnaire which included ways of living, attitudes to PE, and subjective health, the 13-question version of SOC; and information on every student's grades. The study gro

Guidance of eye-movements in image viewing is believed to be controlled by stimulus driven factors as well as viewer dependent higher level factors such as task and memory. It is currently debated to what proportions these factors contribute to gaze guidance, and also how they vary over time after image onset. Overall, the unanimity regarding these issues is surprisingly low and there are results

The isomeric diazadithiapentacenes (3) and (4) were obtained in reactions of 2-chloro-3-bromoquinoline (5) with selected sulfur reagents in various conditions. The 1,4-dithiin ring opening in diazadithiapentacene (3) led to 2,3’-diquinolinyl sulfide or (via the Smiles rearrangement stage of the S→S type) to 3,3’-diquinolinyl sulfide or to diazadithiapentacene (4) depending on reaction conditions.

The present study investigated whether the rotation rate induced by amphetamine in 6-OHDA-lesioned rats was predictive of development of l-DOPA-induced dyskinesia (LID) and success of the lesion procedure in our experimental settings. We collected data from 312 6-OHDA-lesioned rats (from different sets of experiments). Rats were subjected to the amphetamine-induced rotation test (2.5mg/kg) and chr

BACKGROUND: Animal studies suggest that the arginine vasopressin system may play a role in glucose metabolism, but data from humans are limited. METHODS AND RESULTS: We analyzed plasma copeptin (copeptin), a stable C-terminal fragment of the arginine vasopressin prohormone. Using baseline and longitudinal data from a Swedish population-based sample (n=4742; mean age, 58 years; 60% women) and multi
