Urodynamic effects of a novel EP(1) receptor antagonist in normal rats and rats with bladder outlet obstruction.
Purpose: Prostaglandin E-2 and its EP1 receptor were suggested as endogenous modulators of bladder function in the normal physiological state and under pathophysiological conditions. We investigated if the new EP1 receptor antagonist PF-2907617-02 would influence the regulation of normal micturition in rats, and if it affects bladder function in animals with partial bladder outlet obstruction. Mat
Historical diversification of migration patterns in a passerine bird
Migratory strategies of birds require complex orientation mechanisms, morphological adaptations, and life-history adjustments. From an evolutionary perspective, it is important to know how fast this complex combination of traits can evolve. We analyzed mitochondrial control-region DNA sequences in 241 blackcaps (Sylvia atricapilla) from 12 populations with different migratory behaviors. The sample

Scaling up effects in the organic laboratory
A simple, yet safe and effective set of experiments to expose chemistry students to some of the effects that may be encountered when scaling up an organic reaction is described. The exothermic Diels–Alder reaction between maleic anhydride and cyclopentadiene was found to be ideal for our purposes and was performed in small, medium, and large scale for comparison. The observed differences of heat e

The Emergence of Conditional Subordinators in Swedish : A Study in Grammaticalization
This thesis is an empirical and theoretical study of the emergence of five Swedish conditional subordinators: utan, om, hvar, ifall and bara. The first changes occur in the 13th century, and the last in the 18th century. After a theoretical introduction, in which grammaticalization as well as conditionality and conditional structures are critically discussed, five paths of change are identified. T

Age-related increase in wall stress of the human abdominal aorta: An in vivo study
Background: The regulation of wall stress in the abdominal aorta (AA) of humans might be of specific interest, because the AA is the most common site for aneurysm formation in which wall stress seems to be an important pathophysiological factor. We studied the age-related changes in wall stress of the AA in healthy subjects, with the common carotid artery (CCA) as a comparison. Methods. A total of

An Improved Procedure for the Synthesis of Bicyclo[2.2.2]octane- 2,6-dione
Conjugate addition of Meldrum's acid to 2-cyclohexenone followed by direct cyclization in PPA/acetic acid constitutes a shorter, more reproducible and higher yielding route to bicyclo[2.2.2]octane-2,6-dione than previous methods. The crude dione could be used as substrate for the baker's yeast reduction to (IR, 4S, 6S)-bicyclo[2.2.2]octane-6-ol-2-one.

Substance P relaxes rat bronchial smooth muscle via epithelial prostanoid synthesis
BACKGROUND: Substance P is present in bronchial nerve fibres. The physiological actions of substance P are mediated via tachykinin NK(1) receptors. Immunochemical studies have demonstrated tachykinin NK(1) receptors in the rat airway epithelium. OBJECTIVE: To elucidate how epithelial tachykinin NK(1) receptors affect smooth muscle response to substance P. METHODS: Contractile response of isolated

Towards ILBC speech coding at lower rates through a new formulation of the start state search
The Internet Low Bit-rate Coder (iLBC) has emerged as a candidate for Voice over Internet Protocol (VoIP) applications. By avoiding the inter-frame coding dependencies endemic to many speech coders such as those based on Code Excited Linear Prediction, iLBC is able to achieve superior robustness to packet loss. In addition to robustness to packet loss, a VoIP codec should possess the agility to ad
Local changes in cerebral energy metabolism due to brain retraction during routine neurosurgical procedures
Patients and Interventions. Tissue damage caused by brain retraction was evaluated utilizing intracerebral microdialysis in six patients operated on subfrontally for pituitary adenoma. The microdialysis probes (membrane length 10 mm, cut-off 20 kDalton) were placed in cerebral cortex beneath the brain retractor and perfused with Ringer solution at 0.3 mul/min. The microdialysis vials were changed
