Building upon a recent approach pioneered by Barvinok [4, 5, 7, 8] we present a quasi polynomial time algorithm for approximating the permanent of a typical n×n random matrix with unit variance and vanishing mean μ = (ln lnn)−1/6 to within inverse polynomial multiplicative error. This result counters the common intuition that the difficulty of computing the permanent, even approximately, stems ...

DTX, a single-chain polypeptide of M, 7000 from the venom of the eastern green mamba Dendroaspis angusticeps, has been shown to facilitate transmitter release at the neuromuscular junction (Harvey & Karlsson, 1982) and in the central nervous system (Docherty et al., 1983). It is highly toxic when administered centrally (Dolly et al., 19831, producing a convulsant action arising from its facilit...

Background Although several studies confirmed positive effects of fish oil on semen quality, the antioxidant status in omega-3 supplemented diets of several studies is a fuzzy point. The aim of this study was to investigate the effect of dietary fish oil and (or) vitamin E supplementation on cryopreserved sperm in Mehraban rams. MaterialsAndMethods Sixteen fertile rams were randomly allotted to...

Utilization of fecundity genes such as GDF9 and BMP15 can help improve reproductive traits in sheep breeding programme. To evaluate effects of missense mutations on protein function, the polymorphisms of GDF9 and BMP15 genes were screened in twelve mehraban sheep using DNA sequencing, followed by protein structure modeling. Six single nucleotide polymorphism (SNPs) known as FecG mutations (G1-G...

     The family blenniidae comprises 58 genera and 406 species according to Eschmeyer and Fong (2018). Members of the family Blenniidae are small, scale-less and very agile fishes, inhabiting inshore, sub-tidal rocky substrata, and rock pools of the inter-tidal zone of tropical and sub-tropical marine waters (Randall, 1995). A few species are also reported from brackish and freshwaters (Hastin...
