Deviation of the multiplicity distribution Pq in small bin from its Poisson counterpart pq is studied within the Ginzburg-Landau description for second-order quark-hadron phase transition. Dynamical factor dq ≡ Pq/pq for the distribution and ratio Dq ≡ dq/d1 are defined, and novel scaling behaviors between Dq are found which can be used to detect the formation of quark-gluon plasma. The study o...
In this paper, we begin a classification of the vertex-transitive tournaments of order pq where p and q are distinct odd primes. In particular we characterize the pq-circulant tournaments; see Theorem 4.3. Moreover, we determine 2-closed (in Wielandt’s sense) oddorder transitive permutation groups of degree p and pq by using the classifications of vertextransitive tournaments of order p and pq....
In this paper, a SVM classifier based on S-Transform is presented for power quality disturbances classification. Firstly, seven types of PQ events are created using Matlab simulation. These signals are analyzed to detect and localize PQ events via S-Transform by visual inspection. Then five significant features of the PQ disturbances are extracted from the S-Transform output. Afterwards, PQ dis...
background: poisoning with paraquat (pq) is highly fatal. in this study; demographic and clinical characteristics of a series of patients with acute pq poisoning treated at two university hospitals in shiraz, iran are presented and predictive factors for mortality are analyzed. methods: this was an analytical cross-sectional study on consecutive pq poisoned patients admitted to shoushtari and ...
The use of the herbicide paraquat (1,1'-dimethyl-4,4'-bipyridylium dichloride; PQ) which is widely used in agriculture is known to cause dopaminergic neurotoxicity. However, the mechanisms underlying this effect are not fully understood. This present study investigated the behavioral manifestations, motor coordination, and dopaminergic neurodegeneration following exposure to PQ. Male rats were ...
Amyloid -peptide (A ) and Paraquat PQ induce oxidative stress in astrocytes by formation of reactive oxygen species (ROS). The present study determines the cellular response to oxidative stress by use of proton nuclear magnetic resonance ( 1 H-NMR) spectroscopy. The cellular response was studied in cultured primary astrocytes exposed directly to 5 mM PQ or 40 M A (1-40) in the NMR tube (directl...
Paraquat (PQ) is a dopaminergic neurotoxin and a well-known pneumotoxicant that exerts its toxic effect via oxidative stress-mediated cellular injuries. This study investigated the protective effects of Tualang honey against PQ-induced toxicity in the midbrain and lungs of rats. The rats were orally treated with distilled water (2 mL/kg/day), Tualang honey (1.0 g/kg/day), or ubiquinol (0.2 g/kg...
Polyamine (PA) transport as well as PA biosynthesis, degradation and conjugation plays a vital role in the regulation of intracellular PA levels, which are essential for cell growth. Generally, PA uptake activity is elevated in rapidly proliferating cells. Previous studies showed that PA uptake in plant cells occurred via energy-dependent, protein-mediated transport systems. Numerous lines of e...
OBJECTIVE To evaluate the role of rapamycin (RAPA) in paraquat (PQ)-induced acute lung injury. METHODS Lung tissues were stained with HE and lung histology was observed. Mortality rate, and neutrophil and leukocyte count in blood and bronchoalveolar lavage fluid (BALF) were recorded. Protein content in BALF was determined by Coomassie blue staining. Malondialdehyde (MDA) content, glutathione ...
Background Single low-dose primaquine (PQ) reduces Plasmodium falciparum infectivity before it impacts gametocyte density. Here, we examined the effect of PQ on gametocyte sex ratio as a possible explanation for this early sterilizing effect. Methods Quantitative reverse-transcription polymerase chain reaction assays were developed to quantify female gametocytes (targeting Pfs25 messenger RNA...
