Objective: Paraquat (PQ) is a herbicide which induces oxidative stress and inflammation. Anti-inflammatory and anti-oxidant effects were shown for Zataria multiflora (Z. multiflora) and carvacrol previously. The effects of Z. multiflora hydroalcoholic extract and carvacrol on systemic inflammation and oxidative stressinduced by inhaled PQ were examine...

Although QCD axion models are widely studied as solutions to the strong CP problem, they generically confront severe fine-tuning problems to guarantee the anomalous Peccei-Quinn (PQ) symmetry. In this Letter, we propose a simple QCD axion model without any fine-tunings. We introduce an extra dimension and a pair of extra quarks living on two branes separately, which is also charged under a bulk...

paraquat (pq) is a widely used herbicide. however, a large number of cases of accidental or suicidal poisoning from pq has been reported. membrane damage induced by lipid peroxidation, inactivation of protein or damage to dna by radical formation have been suggested as toxicity mechanisms of pq. in the present work, the effects of atropine, propranolol, procainamide and dipyridamole on pq-induc...

Let E pq be the vertical homology Hg(E 0 p∗) of this complex. In other words, if Z pq = ker(d v pq), B pq = im(d v p,q+1), then E pq = Z 1 pq/B 1 pq. We note that d h induces maps E pq → E p−1,q as follows. The condition dd = −dd shows that d(Z pq) ⊆ Z p−1,q and d(B pq) ⊆ B p−1,q; therefore, there is a homomorphism d̃pq : E 1 pq → E p−1,q. Let E pq be the horizontal homology Hp(E ∗q) of this com...

Perturbed Quantization (PQ) steganography scheme is almost undetectable with the current steganalysis methods. We present a new steganalysis method for detection of this data hiding algorithm. We show that the PQ method distorts the dependencies of DCT coefficient values; especially changes much lower than significant bit planes. For steganalysis of PQ, we propose features extraction from the e...

This paper presents a new framework based on modified EMD method for detection of single and multiple PQ issues. In modified EMD, DWT precedes traditional EMD process. This scheme makes EMD better by eliminating the mode mixing problem. This is a two step algorithm; in the first step, input PQ signal is decomposed in low and high frequency components using DWT. In the second stage, the low freq...

The evenness and the values modulo 4 of lengths periods continued fraction expansions p 2p for p≡3(mod4) a prime are known. Here we prove similar results expansion pq, where p,q≡3(mod4) distinct primes.

In this paper we construct OD(4pq(q+1); pq, pq, pq, pq, pq, pq, pq, pq) for each core order q ≡ 3(mod 4), r ≥ 0 or q = 1, p odd, p ≤ 21 and p ∈ {25, 49}, and COD(2q(q + 1); q, q, q, q) for any prime power q ≡ 1(mod 4) (including q = 1), r ≥ 0.
