Endotoxin including lipopolysaccharide (LPS) confers organ tolerance against subsequent challenge by ischemia and reperfusion (I/R) insult. The mechanisms underlying this powerful adaptive defense remain to be defined. Therefore, in this study we attempted to determine whether nitric oxide (NO) and its associated enzymes, inducible NOS (iNOS) and endothelial NOS (eNOS, a constitutive NOS), are associated with LPS-induced renal tolerance against I/R injury, using iNOS (iNOS knock-out) or eNOS (eNOS knock-out) gene-deleted mice. A systemic low dose of LPS pretreatment protected kidney against I/R injury. LPS treatment increased the activity and expression of iNOS, but not eNOS, in kidney tissue. LPS pretreatment in iNOS, but not eNOS, knock-out mice did not protect kidney against I/R injury. In conclusion, the kidney tolerance to I/R injury conferred by pretreatment with LPS is mediated by increased expression and activation of iNOS.

The purpose of this study is to specify the quality of I-R-E pattern and question-answer affiliation between students and teacher, depending on teacher's career. This study analyzes 6 classroom discourse texts of 6th grade science class. The results of this study are as follows. First, in the case of a newly appointed teacher, I-R-E pattern is appeared repeatedly. Second, in the case of experienced teachers, expended I-R-E pattern is appeared compare with a newly appointed teacher. Third, in the case of a newly appointed teacher, independence relational structure is appeared more repeatedly than other structures. But, in the case of experienced teachers, all kinds of question-answer structures - independence, parallel, insertion, and reorganization relational structure - are appeared more evenly.

Al centro dell'interesse di Strehler ci sono sempre l'uomo e le sue azioni, e l'uomo e la posizione del teatro. Inoltre, nei suoi teatri vengono alla luce i rapporti che interessano l'uomo e la societa', l'uomo e se stesso, l'uomo e la storia, l'uomo e la politica. Strehler interpreta sempre i testi prendendo in considerazione la contemporaneita' e completa la rappresentazione strutturandola in un sistema implacabilmente coerente di segni scrulolosi. Poiche' le sue opere, anche se le stesse, sono rappresentate ogni volta con significati diversi a secondo del tempo, non si tratta soltanto di rivivere le opere, ma di metterle in scena in nuove versioni che hanno significati che interpretano i cambiamenti avvenuti. Questo e' anche il caso de I giganti della montagna. Nella prima regia di quest'opera, Strehler cerca di mettere in evidenza una concreta e generale storia umana attraverso il mito, e un messaggio che è al tempo stesso di disperazione e di fede nell'uomo. Un messaggio di perdono e di pietà. Pietà per tutti. Nella seconda regia, egli incarna, attraverso il vuoto dell'immobilita' e il silenzio, la vita della poesia. Cerca di rappresentare l'estremo degli effetti scenici attraverso la minima mobilita' in una scena immobile, e attraverso il massimo grido di dolore in una scena di silenzio. E anche i personaggi sono divisi in due diverse categorie. 'Gli scalognati', che creano 'teatro puro' non per un pubblico ma per puro giuoco, e 'la compagnia dei comici', che crea 'teatro rappresentato' che implica la possibilita' dell'interprete condizionato dai rischi, dagli errori di valutazione e d'interpretazione e che resta legato ad una realta' concreta. Attraverso questo contrasto egli vuole esprimere "il timore che nonostante tanta "rivoluzione" giovanile intorno, il cammino della societa' degli uomini verso l'abbandono di alti ideali e valori, fosse accelerato e quasi ineluttabile". Nella terza regia, i due mondi si incontrano in uno spazio dove realta' e sogno si confondono. Non sono piu' contrapposti. E' come "una tragica contestazione che i Giganti hanno vinto e che ci hanno, consapevoli o inconsapevoli, travolti, che non siamo piu gli stessi, che stiamo precipitando". Ma egli non dispera, benche' rappresenti la condizione tragica, dice al pubblico di "comunicare in silenzio la reciprocita' delle sconfitte. al di la' delle parole che non esistono".

General American English(=A.E.) has conservative elements as well as progressive elements. A.E. and B.E. are languages which have more similarities than differances. In this paper. I studied the process of English progress before the A.E. had come into being, and the historical background and the cahristics of A.E. coming into being. Considering the differences between A.E. and B.E. from spelling, pronunciation, vocabulary and grammar, I can give the outline as follows. A spelling 1. B.E. : au, ou $${\rightarrow}$$A.E. : a, o 2. B.E. : e $${\rightarrow}$$A.E. : i 3. B.E. : $${\ae}$$ oe $${\rightarrow}$$A.E. : e 4. B.E. : our $${\rightarrow}$$A.E. : or 5. B.E. : re $${\rightarrow}$$A.E. : er B. pronunciation 1. B.E. : [e] $${\rightarrow}$$A.E. : [i], [e], $$[\partial]$$ 2. B.E. : [a] $${\rightarrow}$$A.E. : 3. B.E. : [i(:)] $${\rightarrow}$$A.E. : [ai], $$[\partial]$$, $$[{\varepsilon}]$$ 4. B.E. : $$[{\ae}]$$ $${\rightarrow}$$A.E. : [e], [c] 5. B.E. : [ai] $${\rightarrow}$$A.E. : $$[{\ae}]$$, [e] 6. B.E. : [c] $${\rightarrow}$$A.E. : [e], [a], [o] 7. In case of "Vowel+[t]+Vowel", [t] is pronounced into [d] or [r] 8. In case of "-nt", [t] becomes a mute. 9. [t]+[j, l, m, n, r, u, or, w] $${\rightarrow}$$A.E. : [?] (=glottal stop) 10. B.E. : [w] $${\rightarrow}$$A.E. : [hw] 11. B.E. : [Voiceless consonants], [Voiced consonants] $${\leftarrow}$$A.E. : [Voiced consonants], [Voiceless consonants] C. Vocabulary The historical background and geographical conditions of those days caused lots of new compounds and neologies. D. Grammar Though we use "of" to indicate the possessive case of inanimate object, -s genitive is used in A.E. In the perfect tense, "have" is often omitted and also auxiliary verb "will" is used in any case

Interspecific hybrids between tiger grouper Epinephelus fuscoguttatus and giant grouper E. lanceolatus were genetically identified based on the partial sequence analysis of mitochondrial cytochrome c oxidase I (COX I) gene and nuclear recombination activating gene 2 (RAG 2) gene. Out of 585 base positions of RAG 2, a total of five nucleotide substitutions were detected between the two parental species (E. fuscoguttatus and E. lanceolatus). The hybrids had two distinct types of RAG 2 sequences corresponding to those of both parental species. Mitochondrial COX I gene sequencing showed that hybrids had sequences identical to E. fuscoguttatus. Molecular data clearly demonstrate that hybridization does occur between E. fuscoguttatus and E. lanceolatus, but with E. fuscoguttatus as the maternal parent.

Given operators X and Y acting on a Hilbert space $\mathcal{H}$, an interpolating operator is a bounded operator A such that AX = Y. In this paper, we showed the following : Let $\mathcal{L}$ be a subspace lattice acting on a Hilbert space $\mathcal{H}$ and let $X_i$ and $Y_i$ be operators in B($\mathcal{H}$) for i = 1, 2, ${\cdots}$. Let $P_i$ be the projection onto $\overline{rangeX_i}$ for all i = 1, 2, ${\cdots}$. If $P_kE$ = $EP_k$ for some k in $\mathbb{N}$ and all E in $\mathcal{L}$, then the following are equivalent: (1) $sup\;\{{\frac{{\parallel}E^{\perp}({\sum}^n_{i=1}Y_if_i){\parallel}}{{\parallel}E^{\perp}({\sum}^n_{i=1}Y_if_i){\parallel}}:f{\in}H,n{\in}{\mathbb{N}},E{\in}\mathcal{L}}\}$ < ${\infty}$ range $\overline{rangeY_k}\;=\;\overline{rangeX_k}\;=\;\mathcal{H}$, and < $X_kf,\;X_kg$ >=< $Y_kf,\;Y_kg$ > for some k in $\mathbb{N}$ and for all f and g in $\mathcal{H}$. (2) There exists an operator A in Alg$\mathcal{L}$ such that $AX_i$ = $Y_i$ for i = 1, 2, ${\cdots}$ and AA$^*$ = I = A$^*$A.

In this study, we have quantified genotype frequency of the cytochrome P450 (P450) 2E1 which codes for the P450 enzyme primarily responsible for the metabolic activation of carcinogenic nitrosamines and low molecular organic solvents, in Korean population by using PCR and RFLP at two sites previously associated with some cancers; a PstI and RsaI RFLP in the transcriptional regulatory region of the human P450 2E1 gene. The genotype frequencies of homozygous wild type (PstI site-absent) and heterozygous mutant type (PstI site-present) in PstI RFLP were 0.70 and 030, respectively. The homozygous mutant type in Pstl RFLP was not observed in Korean population. The genotype frequencies of homozygous wild type (RsaI site-present), heterozygous mutant type (RsaI site-absent), and homozygous mutant type in RsaI RFLP were 0.71, 0.26, and 0.03, respectively.
