Do Changes in Tumor Blood Flow Necessarily Lead to Changes in Tissue Oxygenation and in Bioenergetic Status?

1994

An increasing number of investigations carried out in recent years provide evidence suggesting that “chronic” decreases in tumor blood flow and/or tissue oxygenation (e.g., during tumor growth) or acute declines in the tissue perfusion (e.g., following therapeutic measures) might be accompanied by significant reductions in the energy status. In several instances, positive correlations between energy status and tumor blood flow or oxygenation have been reported (Lilly et al., 1985; Evelhoch et al., 1986; Tozer et al., 1989; Vaupel et al., 1989a, 1989b; Steen and Graham, 1991), and these investigations have led to the conclusion that blood flow may be the limiting factor in determining the bi…

EVALUATIVE LANGUAGE IN SPOKEN AND SIGNED STORIES TOLD BY A DEAF CHILD WITH A COCHLEAR IMPLANT: WORDS, SIGNS OR PARALINGUISTIC EXPRESSIONS?

2011

In this paper the use and quality of the evaluative language produced by a bilingual child in a story-telling situation is analysed. The subject, an 11-year-old Finnish boy, Jimmy, is bilingual in Finnish sign language (FinSL) and spoken Finnish. He was born deaf but got a cochlear implant at the age of five. The data consist of a spoken and a signed version of “The Frog Story”. The analysis shows that evaluative devices and expressions differ in the spoken and signed stories told by the child. In his Finnish story he uses mostly lexical devices – comments on a character and the character’s actions as well as quoted speech occasionally combined with prosodic features. In his FinSL story he…

A multimodal analysis of facework strategies in a corpus of charity ads on British television

2013

Abstract The aim of this article is to carry out a qualitative multimodal analysis of the codification of verbal and non-verbal politeness strategies in a sub-corpus of five charity commercials aired on British television. Brown and Levinson's (1987) verbal politeness strategies are taken as a starting point together with a detailed analysis of facework that is realized through paralinguistic and extralinguistic modes of communication ( Kress and van Leeuwen, 2006 , Machin, 2010 ). In what we have identified as the problem phase of the commercial, our analysis has revealed that advertisers deliberately attempt to create threats to the viewer's positive and negative face by making him/her fe…

Carotid artery stenting with contralateral carotid occlusion in a rare aortic arch configuration

2010

We present the case of a 47-year-old man admitted to our department with an episode of aphasia. Duplex scan showed an occluded right internal carotid artery and severe left internal carotid artery stenosis. Contrast-enhanced computer tomography demonstrated a common trunk for both common carotid arteries anterior to the trachea and aberrant right subclavian artery posterior to the esophagus. The patient was considered to be a high risk for carotid endarterectomy and, consequently, we performed stenting of the left carotid artery. To our knowledge, this is the first case reporting the combination of these two aortic arch anomalies and the concomitant endovascular treatment of atherosclerotic…

The condition of the contralateral knee may induce different degrees of knee extensor strength asymmetry and affect functionality in individuals with…

2020

Abstract Background Loss of knee extensor strength in individuals with knee osteoarthritis (KOA) may induce inter-limb strength asymmetries and alter functionality. The aims were to analyse whether the condition of the uninvolved knee (advanced to severe KOA or no affection) may induce different degrees of knee extensor strength asymmetry in individuals with KOA and to study whether functionality may differ in cases of unilateral or bilateral KOA. Methods Sixty-eight subjects with advance-to-severe KOA were categorized into two groups (unilateral or bilateral KOA). The knee extensor strength ratio (KESR), and self-reported and performance-based functionality were analysed and compared. Sex …

Propyldazine is mutagenic inSalmonella typhimurium and Escherichia coli: Distinct specificity for strains TA1537 AND TA97

1985

The antihypertensive drug propyldazine (Atensil) was demonstrated to be muta- genic with auxotrophic mutants of Salmonella typhimurium and Escherichia coli. Addition of liver S9 mix (postmitochondrial supernatant fraction supplemented with an NADPH-generating system) had little, if any, effect on the mutagenicity. The mutagenicity showed an unusual pattern of strain specificity. Increased fre- quencies of reversion were observed with all strains whose auxotrophy was caused by frame-shift mutations: the number of revertant colonies per plate from S. typhimurium TA98, TA1538, TA97, and TA1537 was increased up to 5-, 9-, 43-, and 160-fold, respectively, above background. Among the strains that…

Acute effects of three isoflavone class phytoestrogens and a mycoestrogen on cerebral microcirculation.

2007

Phytoestrogens and mycoestrogens are naturally occurring plant and fungus secondary metabolites with estrogen-like structure and/or actions. We aimed to check the hypothesis that phytoestrogens and mycoestrogens, due to their ability to elicit cerebral vasodilation, can induce acute increases in brain blood perfusion. For this purpose, we continuously recorded cerebrocortical perfusion by laser-Doppler flowmetry in anesthetized rats receiving intracarotid infusions (1 mg/kg) of one of the following estrogenic compounds: biochanin A, daidzein, genistein or zearalanone. We have shown the ability of two isoflavone class phytoestrogens (daidzein and biochanin A) and the mycoestrogen zearalanone…
