Spreading depression (SD) is characterized by a sustained near-complete depolarization of neurons, a massive depolarization of glia, and a negative deflection of the extracellular DC potential. These electrophysiological signs are accompanied by an intrinsic optical signal (IOS) which arises from changes in light scattering and absorption. Even though the underlying mechanisms are unclear, the ...
Rat liver 3alpha-hydroxysteroid/dihydrodiol dehydrogenase (3alpha-HSD/DD), a member of the aldo-keto reductase superfamily, inactivates circulating steroid hormones and may contribute to the carcinogenicity of polycyclic aromatic hydrocarbons (PAHs) by oxidizing trans-dihydrodiols to reactive o-quinones with the concomitant generation of reactive oxygen species. The 3alpha-HSD/DD gene has been ...
11beta-Hydroxysteroid dehydrogenases (11beta-HSD) are microsomal enzymes that catalyze the conversion of active glucocorticoids (GC) to their inactive 11-dehydro products and vice versa. Two isoenzymes of 11beta-HSD have been characterized and cloned in human tissues. The tissue-specific metabolism of GC by these enzymes is important for mineralocorticoid (MC) and GC receptor occupancy and seem...

The case report on Hallervorden Spatz disease (HSD)(1) aroused interest, particularly because we are currently managing a child with this disease in our Pediatric Neurology Clinic. Although the authors have rightly suspected the condition, they have not presented parameters on the basis of which the diagnosis was made. Absence of criteria for Wilson's disease and presence of family history of s...
A holey Schrr oder design of type h n 1 1 h n 2 2 h n k k (HSD(h n 1 1 h n 2 2 h n k k)) is equivalent to a frame idempotent Schrr oder quasigroup (FISQ(h n 1 1 h n 2 2 h n k k)) of order m with n i missing subquasigroups (holes) of order h i ; 1 i k, which are disjoint and spanning, that is , P 1ik n i h i = m. In this paper, we rst consider the existence of HSD(2 n u 1) for 1 u 4 and show tha...
گل انگشتانه digitalis nervosa از جمله گیاهان دارویی است. تری بتا-هیدروکسی استروئید دهیدروژناز یک ژن کلیدی مهم در مسیر بیوسنتزی گلیکوزید ها است. با استفاده از آغازگرهای حفظ شده ژن 3?-hsd اقدام به جداسازی و توالی یابی این ژن شد. بیان ژن 3?-hsd و سه ژن mlncrna23,28,30 از طریق rt-pcr نیمه کمی انجام شد. بررسی توالی-حاصل نشان داد که ژن 3?-hsd انگشتانه مشابهت زیادی با همین ژن در سایرگونه های خویشاوند ...
The 3beta-hydroxysteroid dehydrogenase/isomerase (3beta-HSD) isoenzymes catalyze an essential step in the formation of all classes of active steroid hormones. In humans there are two 3beta-HSD isoenzymes, the type 1 gene being predominantly expressed in the placenta and peripheral tissues, whereas the type 2 gene is the predominant 3beta-HSD expressed in the adrenal glands and gonads. We have r...
This paper describes a new data structure called the \Haar Spectral Diagram" (or HSD) useful for representing the Haar spectrum of boolean functions. An alternative ordering of Haar coe cients is used to represent the Haar transform matrix in terms of a Kronecker product yielding a natural decision-diagram based representation. The resulting graph is a pointdecomposition of the Haar spectrum us...
