background tyrosinase, as a copper-containing enzyme, is widely distributed in different levels of life span. it is also a key enzyme in melanin biosynthesis, which plays a crucial role in determining the color of mammalian skin and hair. objectives the current study aimed to determine the effect of a palladium complex on cresolase and catecholase reactions of mushroom tyrosinase (mt). material...

Pseudomonas fluorescens SBW25 is capable of growing on histidine as a sole source of carbon and/or nitrogen. Previous work showed that the two-component regulatory system CbrAB is required for expression of the histidine utilization (hut) locus when histidine is the sole source of carbon and nitrogen. Here, using mutational analysis and transcriptional assays, we demonstrate involvement of a se...

Liquid enteral formulas are commonly used as a sole source of nutritional support of patients in hospital and community settings. Their effect on appetite has important consequences for dietary management of such patients and is likely to be affected by the formula composition. The aim of the present study was to compare appetite within healthy subjects consuming both a standard formula and one...

a consortium of biofertilizers (azotobacter chroococcum and bacillus subtilis) was applied in conventional as well as organic matrix entrapped granular forms as sole nutrient source in two different doses for cultivation of wheat (triticum aestivum l. cv. pbw-343). a double dose of conventional biofertilizers increased the growth of wheat plants as measured on 30, 60, 90, and 120 days after sow...

this work reports the comparative study of heavy metal water concentrations fromtwo coastal ecosystems ofcadizgulf (swspain): bay of cadiz and ria ofhuelva estuary in samplestaken on years 1999-2000. sampling zones showed different heavymetal levels. statistical analysisof dissolved trace metal concentrations (cu, zn, cd and pb) showed significant differences betweenhuelva and cadiz zones based...

let  be a banach algebra. let  be linear mappings on . first we demonstrate a theorem concerning the continuity of double derivations; especially that all of -double derivations are continuous on semi-simple banach algebras, in certain case. afterwards we define a new vocabulary called “-higher double derivation” and present a relation between this subject and derivations and finally give some ...

A field experiment was conducted at Sugarcane Research Station, Tamil Nadu Agricultural University, Sirugamani during (Plant crop) 2017-18 to find out the effect of intercropping and double row planting on growth attributes, yield sugarcane under Sustainable initiative. The experiments were laid in a strip plot design with three replications. main treatments comprised crop geometry viz., M1- 15...
