background: the present study investigated the effects of lead nitrate on the histo-cytological changes in the corpuscles of stannius (cs) of heteropneustes fossilis. methods: catfish, heteropneustes fossilis were subjected to 657.6 mg/l and 164.4 mg/l of lead nitrate for 96 h and 28 days, respectively. blood from fish was collected on 24, 48, 72 and 96 h in short-term and after 7, 14, 21, and ...

the effects of hydroalcoholic extract (he) of curculigo orchioides gaertn. rhizome (hypoxidaceae) and its alkaloidal and non-alkaloidal fractions (af) and (naf) were evaluated in carrageenan-induced paw edema experimental models of inflammation. the oral administration of he, their af and naf fractions were used at doses of 100, 300 and 500 mg/kg. the effect produced by the he, af and naf fract...

In Reply: The comments of Dr Wiwanitkit are well taken. In our article (1), our main concern was to emphasize the big difference between plagiarism of ideas and plagiarism of text, especially in scientific writing, where we believe text is just a transfer medium for ideas, which are the essence of scientific work (2-5). Paraphrasing of a scientific text is not always easy, if possible at all (6...

Since Bolinger’s [1] discovery that pitch cues accentual prominence in English, a tension has arisen between two strategies: equating accent with pitch excursions and relying on perception for identifying accented words. This paper investigates the relation between prominence judgments from untrained listeners and accentual labels produced by trained transcribers. Naïve speakers of English, Spa...

We performed a cognitive experiment in order to obtain evidence that prosody is used for the segmentation of continuous speech for understanding in real time. We assume that the cognitive unit in Japanese speech is the accentual phrase (AP) which is represented by low and high pitch patterns according to the Japanese accent rule. Meaningless speech which consisted of two APs was used as the exp...

Correspondence Only six patients without previous AFib were given antiarrhythmic drugs (AADs), and interaction between AADs and CPAP did not infl uence the incidence of AFib during follow-up among them ( P 5 1) (our unpublished data, 2013). CPAP did not add any clinical benefi t to AADs in patients with previous AFib documentation ( P 5 .53, unpublished data). Compliance and duration of CPAP us...

We consider the deblurring problem of noisy and blurred images in the case of known space invariant point spread functions with four choices of boundary conditions. We combine an algebraic multigrid previously defined ad hoc for structured matrices related to space invariant operators (Toeplitz, circulants, trigonometric matrix algebras etc.) and the classical geometric multigrid studied in the...

The effect of ascorbic acid (AA) and butylated hydroxyanisole (BHA) supplementation on aflatoxicosis in broiler chickens (1 to 42 days of age) was investigated (250, 500, 1000 and 2000 ppm for AA and BHA) in diet containing 1 ppm total aflatoxin (AF: 76.45% AFB1, 10.52% AFB2, 9.89% AFG1 and 3.14% AFG2). A total of 300 day-old broiler chicks were divided into ten treatment groups (T1=control; T2...
