The paper focuses on the changes of nitrogen compounds in the Pipe network. A 1.2km long urban sewage simulation network with artificial water distribution was selected as the research subject. Then we analyzed and evaluated the change characteristics of nitrogen nutrients along the pipe. The

Dorsoventral (DV) axis formation in Drosophila begins with selective activation of EGFR, a receptor tyrosine kinase (RTK), in dorsal-anterior (DA) ovarian follicle cells. A critical event regulated by EGFR signaling is the repression of the sulfotransferase-encoding gene pipe in dorsal follicle

There is a global increase in the popularity of water-pipe tobacco smoking including in Europe and North America. Nevertheless, little is known about the male reproductive effects of water-pipe smoke (WPS), especially after long-term exposure. Here, we assessed effects of WPS exposure (30 min/day)

Background: Amide alkaloidsare typical constituents in plants of the Piperaceae family. Most of the pharmacological properties of Piper nigrum L. are attributed to the major amide alkaloid, piperine. Piperyline (PIPE) is a further amide

The protein disulfide isomerase (PDI)-related protein Wind is essential in Drosophila melanogaster, and is required for correct targeting of Pipe, an essential Golgi transmembrane 2-O-sulfotransferase. Apart from a thioredoxin fold domain present in all PDI proteins, Wind also has a unique

In Drosophila melanogaster, the Ras signal transduction pathway is the primary effector of receptor tyrosine kinases, which govern diverse developmental programs. During oogenesis, epidermal growth factor receptor signaling through the Ras pathway patterns the somatic follicular epithelium,

Chromatography on DEAE cellulose equilibrated with Pipes buffer resolved three forms of chorismate mutase (CM) from tubers and leaves of Solanum tuberosum: CM-1A and CM-1B were activated by tryptophan and inhibited by phenylalanine and tyrosine; CM-2 was unaffected by these aromatic amino acids.

Oxidation of β-lactoglobulin (β-Lg), a typical milk whey protein, was investigated by oxidizing its three tryptic peptides after separation and fractionation by preparative HPLC. Oxidation was performed with H2O2 and Fe(3+) in piperazine-1,4-bis(2-ethanesulfonic acid) (PIPES) buffer containing

The Thermomyces lanuginosa lipase has been extensively studied in industrial and biotechnological research because of its potential for triacylglycerol transformation. This protein is known to catalyze both hydrolysis at high water contents and transesterification in quasi-anhydrous conditions.

Biofilm formation is ubiquitous on the corroded inner surface of water distribution pipes. Extracellular polymeric substances (EPS) secreted by biofilm microorganisms are nonnegligible precursors of disinfection byproducts (DBPs). The aim was to study the catalysis of copper corrosion products
