Abalraet--The effect ofafiatoxin on the activities of 5 rat liver lysosomal enzymes (acid deoxyribonuclease, arylsulfatases A and B, ß-glucuronidase, ß-gluoosidase and ß-galactosidase) has been investigated In vivo and t vitro. Threehours afterthe administration of atjatoxin, activities of most of the enzymes increased significantly reaching maximal levels at 48 hr. The activity of acidDNase in...

Cesarean scar pregnancy (CSP) is a rare, but life-threatening type of ectopic pregnancy. An exact and early diagnosis of CSP is very important for prognosis. The aim of the present study was to describe 4 women with CSP and discuss their clinical presentations, diagnoses, and various management options along with the published literature. Four women with a suspicion of CSP or cervical pregnancy...

The monohydroxy carotenoid from the moth Cerura vinula has been shown to be /?,/?-caroten-2-ol on the basis of electronic, infrared, proton magnetic-resonance, and mass spectra. On acid treat­ ment in the presence of molecular oxygen this carotenoid is dehydrogenated to 4',5-retro-ß,ßcaroten-2-one. The identification of /?„/?-caroten-2-ol by its retro product, its time course of acetylation, an...

the aim of this work was to study the ability of two biodegradable chelating agents, nitrilotriaceticacid (nta) and ethylenediiminopropanedioic acid (eddm) to complex metals, in the treatment of the pulp,prior to a totally chlorine free (tcf) bleaching process, and compare with the ethylenediaminetetraacetic acid(edta) performance. firstly, speciation efficiency index (sei) was calculated by co...

ß-Glucuronidase is the novel enzyme known to present in the tissues of several vertebrates. It can be detected by biochemical, histochemical and immunocytochemical techniques in bacteria, plant and animal. The traditional method used for histochemical demonstration of ß-glucuronidase is quite tedious and substrate utilized in a given concentration is not affordable to researchers of the develop...

To further elucidate the possible involvement of intracellular protein catabolism in the development of insecticide resistance, we determined in vivo effect of the potent synthetic pyrethroid, ß-cyfluthrin on the activities of cytoplasmic and lysosomal proteolytic enzymes in insecticide-resistant and susceptible strain of housefly, Musca domestica. ß-Cyfluthrin at LC50 dose after 48 hour treatm...

In this note we prove a theorem concerning the two cardinal problem (see [l], [4], [6], [7] for reference and for some of the standard notation); this result has been referred to in [6, p. 311] and [7, (3.7) ]. The problem, first proposed by Vaught, is as follows. Let T be a first-order theory and let U be a unary predicate symbol in the language of T. T is said to admit the pair a, ß of cardin...

Let F be a (topologically) finitely generated free pro-p-group, and ß an automorphism of F . If p ^ 2 and the order of ß is 2 , then there is some basis of F such that ß either fixes or inverts its elements. If p does not divide the order of ß , then the subgroup of F of all elements fixed by ß is (topologically) infinitely generated; however this is not always the case if p divides the order o...

The aim of the study was to evaluate influence 17% ethylenediaminetetraacetic acid (EDTA) and ethanolic extract Sapindus mukorossi (S. mukorossi) in combination with canal shaping on surface properties ProTaper Gold rotary endodontic file. Sixteen F1 files underwent standard protocol for root treatment using two irrigants EDTA) single-rooted decoronated teeth. Eight unused were used as a contro...
