The aim of the present study was to investigate the lipid pattern in Jordanian children with Beta-thalassemia major (ß-TM). Twenty six transfusion dependent ß-TM patients, 14 males and 12 females, (mean age 9 ± 5 years) that undergo periodical blood transfusion and desferioxame as a chelating agent, were studied. Twenty controls of matched age and gender were also included in the study. ß-thala...

BACKGROUND: ß -estradiol is a steroid sex hormone that plays important role in oral physiology. The aim of this study was to determin the association of the menstrual cycle and salivary ß-estradiol with the production of volatile sulfur compounds (VSC).METHODS: In this cross-sectional study, twenty female dental students in good oral and general health were recruited for evaluation of VSC, sali...

BACKGROUND Viral infection and anti-cardiac immunity are involved in the pathogenesis of dilated cardiomyopathy (DCM). Immunity targeting particular antigens may evoke expansion of reactive T-cell clones. MATERIAL AND METHODS Myocardial tissues from explanted hearts were investigated for clonal T-cell-receptor- (TCR-) ß rearrangements by an established semi-nested polymerase chain reaction (P...

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...

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...

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...

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...

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...
