Effects of chronic caloric restriction on kidney and heart redox status and antioxidant enzyme activities in Wistar rats

BMB Reports , 2012,
Abstract: Caloric restriction (CR) has been associated with healthbenefits and these effects have been attributed, in part, tomodulation of oxidative status by CR; however, data are stillcontroversial. Here, we investigate the effects of seventeenweeks of chronic CR on parameters of oxidative damage/modification of proteins and on antioxidant enzyme activitiesin cardiac and kidney tissues. Our results demonstrate that CRinduced an increase in protein carbonylation in the heartwithout changing the content of sulfhydryl groups or theactivities of superoxide dismutase and catalase (CAT).Moreover, CR caused an increase in CAT activity in kidney,without changing other parameters. Protein carbonylation hasbeen associated with oxidative damage and functionalimpairment; however, we cannot exclude the possibility that,under our conditions, this alteration indicates a differentfunctional meaning in the heart tissue. In addition, wereinforce the idea that CR can increase CAT activity in thekidney.

Abstract: Acoustic, stapedial reflex represents a response of the m. stapedius to a sonic excitation of supra speech intensity. It is the constitutive part of impendancmetric investigations, it is performed on the same apparatus after tympanometry, and it is the inseparable part in representation of impendancmetric findings. Until now, the most frequently monitored parameters of acoustic reflex of clinical importance are: threshold amplitude, output and input angle of the reflex curve. The aim of this work was to performed detailed analysis of mentioned parameters in workers exposed to extensive action of industrial noise of known physical characteristics (of different durations) and to establish which changes occurred in these workers, to what extent and under which conditions. Investigations included 173 industrial workers (346 ears), which work in working unit "Forge", where during the working process noise is produced which is above permissible limits and of the unfavorable frequency content. Workers were divided into two groups. The first group consisted of workers who were spending the whole working time in the workroom with noise above permissible limits, the second group consisted of workers who were spending 3 hours of the working time in that workroom, while the control group consisted of workers who were spending the whole working time in that workroom but they did not have any hearing impairment. Workers of the first and the second group had the hearing impairment, which occurred exclusively as a consequence of chronic acoustic trauma. For all the workers the anamnesis was taken, as well as ORL status and audiometric and impendancmetric investigations were performed, namely the tympanometry and acoustic reflex. Results have shown that the acoustic reflex threshold at 500 Hz and at 1000 Hz for the first group (95.10 dB) was increased with respect to the reflex threshold of the second and the control group (84 dB). At higher frequencies of 2000 Hz and 4000 Hz an increase of the reflex threshold was found for the first and the second group (96 dB) with respect to the control group (87 dB).The amplitude of acoustic reflex was increased at frequencies 500 Hz and 1000 Hz (3.38), with respect to the second group (2.78) and the control group (2.36), and at higher frequencies, this increase is more prominent. The input angle of the reflex curve was, for the first and the second group, within limits 41° to 50°, and for the control group was from 31° to 50°. The output angle was, at majority of ears of the first and the second group, from 26° to 35°, and for the
Factors influencing the choice of prescribed hearing aid

Abstract: In our paper we would like to emphasize the complexity of hearing aid prescription process. It is connected to a series of factors which impact the choice of hearing aid; type of hearing loss, degree of hearing loss according to the average hearing threshold expressed within the range from 500 Hz to 4000 Hz on a tonal audiogram, audiometric curve configuration, speech discrimination ability, patients’ age at which the hearing impairment occurred, time elapsed between the occurrence of hearing impairment and prescription of a hearing aid, patients’ age, physical and mental health and their cognitive function, anatomical characteristics of the auricle and external auditory canal, patient and parent motivation, cosmetic factors, financial abilities, cooperation with hearing aids manufacturers. This paper is important for everyday practice and can be used as a kind of guideline to the hearing aid prescription process.
Estimates of convolutions of certain number-theoretic error terms

International Journal of Mathematics and Mathematical Sciences , 2004, DOI: 10.1155/s0161171204305156
Abstract: Several estimates for the convolution function C [f(x)]:=∫1xf(y) f(x/y)(dy/y) and its iterates are obtained when f(x) is a suitable number-theoretic error term. We deal with the case of the asymptotic formula for ∫0T|ζ(1/2
On the responsibility concept and the agentive role of the instrument used for the action performance
Ivi? Milka
Ju?noslovenski Filolog , 2002, DOI: 10.2298/jfi0258015i
Abstract: It is well established that the choice of subject depends on what the speaker estimates as most responsible for the successful occurrence of the action he is speaking of. The author enlightens the principles according to which in Serbian such a subject promotion may concern objects conceived as instruments indispensable for the performance of the transitive activity denoted by the sentence predicate verb. Pointing, however, to some Dutch language facts which make it quite evident that those principles are by no means universally valid, she claims that still more information about the whole problem are needed. She is, namely, convinced that such line of inquiry would not only enrich our present knowledge of micro parametric variations within the linguistic world, but could also be of relevant help to those researchers who expect, through observation of the facts of language, to get better insights into the ways the human brain works.
The informative role of presupositions and implications confirmed by Serbian language data
Ivi? Milka
Ju?noslovenski Filolog , 2007, DOI: 10.2298/jfi0763001i
Abstract: Today all linguists are likely to agree that the correct interpretation of an utterance consists of the identification of what was ment by it. It has been pointed out that, besides their literal meaning, utterances may have informationally relevant presupositions or implications, which also need to be identified. The author’s analysis discloses some ways in which Serbian language data provide new support for this view.
The cognitive and grammatical aspects of the evaluative use of dobar
Ivi? Milka
Ju?noslovenski Filolog , 2005, DOI: 10.2298/jfi0561001i
Abstract: Drawing on a corpus of conversational Standard Serbian materials, the author examines the ways in which the adjective dobar performs its evaluative function. She points to the following hitherto unnoticed facts: If the evaluation concerns an adult human being dobar is perceived as a moral quality, whereas to say of a child that he is dobar is to praise his behavioral property. If nomina professionalis are concerned, although syntactically used as an attributive adjective, dobar semantically functions in fact as an adverbial modifier disclosing the appropriate performance of the activities which make the person under consideration properly qualified for his/her occupation.
On the anthropocentric theory and Serbian language data
Ivi? Milka
Ju?noslovenski Filolog , 2006, DOI: 10.2298/jfi0662001i
Abstract: The goals of this paper are twofold. First, it is intended to highlight the reasons why now, in our days, many competent language investigators mention the problematic status of the famous anthropocentric theory. Second, it argues for the investigation of a problem which has so far received almost no attention, i.e. it focuses on some earlier Serbian lexical data, pointing to the unexpected fact that they fail to disclose the essential Human/non-human distinction. Namely, the lexical units ivotinja, ivina, ivin e have been used in umadija to denote all living things, including human beings.

On the implicational/non-implicational semantics of adjectives and adverbs occurring in an utterance which contains the information 'more than'
Ivi? Milka
Ju?noslovenski Filolog , 2007, DOI: 10.2298/jfi0763007i
Abstract: This paper considers Serbian adjectives and adverbs denoting qualification property Z in cases when they occur in an utterance of the type ’X is more Z than Y’. The author’s analysis makes it evident that, depending on the lexical meaning of the given adjective / adverb, Z either does, or does not imply that both the X and Y entities are qualified by it. She shows moreover how, by introducing the word jo into his utterance, the speaker succeeds to attribute the property Z to both X and Y in spite of its non-implicational meaning.
