•Guanosine quadruplex hydrogels were modified with ligand 1 enabling Eu(III) binding •Two of the gels both exceptionally stable and partially self-healable •Eu(III)-centered circularly polarized luminescence was observed for one hydrogel •The helical nature guanosine quadruplexes influenced Eu(III)-centered CPL The formation bio-inspired healable lanthanide luminescent is detailed. These materi...

Two experiments were conducted to determine the effect of sources of dietary zinc on gain, feed conversion and blood and bone traits of swine. In the first experiment 96 pigs were used in a 28-d study. The pigs were fed diets with no supplemental Zn or with either 9 or 12 ppm supplemental Zn from zinc sulfate (ZnSO4), zinc methionine (ZnMet) or zinc methionine with picolinic acid (ZnMet w/PA), ...

2-aminophenol (2-AP) is a toxic nitrogen-containing aromatic pollutant. Burkholderia xenovorans LB400 possess an amn gene cluster that encodes the 2-AP catabolic pathway. In this report, the functionality of the 2-aminophenol pathway of B. xenovorans strain LB400 was analyzed. The amnRJBACDFEHG cluster located at chromosome 1 encodes the enzymes for the degradation of 2-aminophenol. The absence...

Rats made diabetic with alloxan have been shown to excrete less Nmethylnicotinamide than normal rats when given test doses of tryptophan (2). The present investigation was designed to determine the nature of the enzymatic alteration responsible for the difference between the two groups of animals. A deficiency in one or more of the enzymes needed for the conversion of tryptophan to nicotinic ac...

This work aims to shed light on the scale-up a combined electrokinetic soil flushing process (EKSF) with permeable reactive barriers (PRB) for treatment of spiked clopyralid. To do this, remediation tests at lab (3.45 L), bench (175 L) and pilot (1400 scales have been carried out. The PRB selected was made merged particles zero valent iron (ZVI) granular activated carbon (GAC). Results show tha...

In crystal engineering and medicinal chemistry, cocrystals have enormous applications. Hydrochlorothiazide (HTZ) is found to form with picolinic acid (HCP1), pyrazinamide (HPP2) isonicotinic (HIP3). order predict energy properties model potential charge transfer between cocrystal constituents, FMOs energies are used. The frontier molecular orbital analysis reveals the cocrystal’s chemical react...

The regulation of tryptophan-niacin metabolism was studied in vivo with regard to the activity of liver ƒ¿-amino-ƒÀcarboxymuconate-c-semialdehyde decarboxylase (picolinic carboxylase) using non-diabetic and diabetic rats. Non-diabetic rats and rats with diabetes induced by alloxan were fed on a commercial diet for 80 days, followed by a niacin-free experimental diet for the next 16 days. Protam...

In 1956, McDaniel, Hundley, and Sebrell (1) reported that urinary excretion of N’n~ethylnicotinamide decreased in alloxan-diabetic rats. Mehler, McDaniel, and Hundley (2) subsequently showed that the level of liver picolinic carboxylase increased markedly in alloxan-diabetic rats and was inversely related with urinary excretion of N’-methylnicotinamide. Previous nutritional studies have indicat...
