We investigated nucleotide polymorphism in the Adh1 locus of pearl millet (Pennisetum glaucum) (Poaceae) by determining the DNA sequence of 20 alleles from 10 individuals. The individuals were sampled from throughout pearl millet's indigenous range and represent both wild and cultivated accessions. Our results indicated that there is little nucleotide polymorphism in the Adh1 locus. Estimates o...

The Pearl River, with an annual mean discharge rate of ~ 10,000 ms, has profound dynamic and ecological influences on the northern shelf of the South China Sea. A coastal ocean model is set up to simulate the circulation in the Pearl River Estuary and the neighboring coastal regions. In winter the Guangdong Coastal Current, which flows southwestward and passes the mouth of the estuary, forces t...

Galles and Pearl [1998] claimed that “for recursive models, the causal model framework does not add any restrictions to counterfactuals, beyond those imposed by Lewis’s [possible-worlds] framework.” This claim is examined carefully, with the goal of clarifying the exact relationship between causal models and Lewis’s framework. Recursive models are shown to correspond precisely to a subclass of ...

The do-calculus was developed in 1995 to facilitate theidentification of causal effects in non-parametric mod-els. The completeness proofs of [Huang and Valtorta,2006] and [Shpitser and Pearl, 2006] and the graphi-cal criteria of [Tian and Shpitser, 2010] have laid thisidentification problem to rest. Recent explorations un-veil the usefulness of the do-calculus in three ...

incontinentia pigmenti (ip) is an x-linked dominant genodermatosis characterized by typical skin lesions along blaschko's lines and associated with ocular, dental, nails, hair, skeletal, central nervous system and cardiovascular anomalies. we report a 5-year-old boy with cutaneous hyperpigmentation along blaschko's lines, atrophic streaks, strabismus and mental retardation. he showed the charac...

Planktonic larvae of many invertebrates settle preferentially on surfaces covered by bacterial biofilms. The polychaete tubeworm Hydroides elegans is induced to settle by biofilms and is the primary colonizer of newly submerged surfaces in the succession of macrofouling invertebrates in Pearl Harbor, Hawai'i. This study examines cultureindependent community composition, as well as densities of ...

We reported pearl oyster Pinctada fucata cDNA and genomic characterization of a new homeobox-containing protein, PfMSX. The PfMSX gene encodes a transcription factor that was localized to the nucleus. Analyses of PfMSX mRNA in tissues and developmental stages showed high expressions in mantle or D-shaped larvae. In electrophoretic mobility shift assays (EMSAs) PfMSX binded to MSX consensus bind...

Background: Melanin is a negative charge hydrophobic complex pigment. Melanin is produced naturally in bacteria to protect them against UV, free radicals and environmental stresses. Pigment production in bacteria has more advantages than other biosources due to its rapid growth, higher efficiency and easier extraction. The aim of this study was the isolation, biochemical and molecular identific...

Background: Many of the most common cancers, such as prostate and breast cancer are due to the presence of harmful agents and compounds in processed foods, including nitrite. In this research the physicochemical, antioxidant, and color properties of sodium nitrite-free sausages containing different concentrations of cochineal pigment alone or in combination with cumin essential oil were studied...

The inkjet printing machine was initially used on ceramic parts as a small device in designing and advertising offices limitedly. In recent years, this device has been applied professionally to create high-quality patterns in the industry. In this method, liquid ceramic ink is sprayed on the specified parts by piezoelectric nozzles and after drying and discharging, the organic matter is baked a...
