To assess the association between polymorphisms of the IL-6 -174 G/C and Behçet's disease (BD) in Tunisian patients. DNA was extracted from blood samples taken from 43 Tunisian patients and 43 healthy controls. The polymorphisms were analyzed by PCR with the PCR-RFLP. No significant association was found between patients and controls concerning polymorphism of IL6 -174 G/C between the (allelic ...

Bacteriophage 46X174 temperature-sensitive and nonsense mutations in eight cistrons were mapped by using two-, three-, and four-factor genetic crosses. The genetic map is circular with a total length of 24 X 104 wt recombinants per progeny phage. The cistron order is D-E-F-G-H-A-B-C. High negative interference is seen, consistent with a small closed circular deoxyribonucleic acid molecule as a ...

For every permutation where 4 is before 5, there is a matching permutation where 5 is before 4, obtained by swapping 4 and 5. That’s a 1-1 correspondence between the two sets of permutations, so they must have the same size, and partition the set of all permutations into two halves. Since all permutations are equally likely, the total probability for the event (4 is before 5) equals the probabi...

But we already saw that some random variables (e.g. the number of balls in a bin) fall off exponentially with distance from the mean. So Markov and Chebyshev are very poor bounds for those kinds of random variables. The Chernoff bound applies to a class of random variables and does give exponential fall-off of probability with distance from the mean. The critical condition that’s needed for a C...

Chalcones (1,3-diaryl-2-propen-1-ones), a flavonoid subfamily, are widely known for their anti-inflammatory properties. Propenone moiety in chalcones is known to play an important role in generating biological responses by chalcones. In the present study, we synthesized chalcone derivatives structurally modified in propenone moiety and examined inhibitory effect on nitric oxide (NO) production ...

The authors summarize their experience with 174 patients with aplastic anaemia (AA) with particular reference to course, prognostic factors, conversion to other blood disorders, treatment and outcome. Aplastic anaemia was defined as pancytopenia and a hypocellular marrow at some time during the illness. Seven patients terminated with acute leukaemia, 8 developed haematological features of sider...

By using Rough Set Theory and the concept of attribute significance, the paper analyzes the approximate and detail component at different scales got by the wavelet transform of the original image, then adopts a knowledgereduction-based algorithm according to its importance in the signal classification, finally extracts the wavelet energy which is the most sensitive to signal characteristics in ...

This is a remarkable volume. Winner of the Lakatos award, given biennially for the book in the philosophy of science most highly regarded by an international committee, it is also crammed with formulas that will be of practical importance, as well as of interest, to epidemiologists, lawyers, economists, and other down-to-earth folk. This is not to say that it will be easy to read, for anyone, o...

Background: Like many viruses, bacteriophage X174 packages its I)NA genome into a procapsid that is assembled from structural intermediates and scaffolding proteins. The procapsid contains the structural proteins F, G and H, as well as the scaffolding proteins B and D. Provirions are formed by packaging of DNA together with the small internal J proteins, while losing at least some of the B scaf...
