Due to the visual appearance and high carotenoid content, orange inner leaves are a desirable trait for the Chinese cabbage. To understand the molecular mechanism underlying the formation of orange inner leaves, the BrCRTISO (Bra031539) gene, as the Br-or candidate gene, was analyzed among the white and orange varieties, and 7 single nucleotide polymorphisms (SNPs) were identified. However, onl...

2,4-Dichlorophenoxyacetic acid (2,4-D) is an herbicide that was one of the two active ingredients in Agent Orange, the Vietnam War defoliant. Although the main health effects of Agent Orange were blamed on the other component of the mixture (2,4,5-T) and dioxin contamination, the data indicate that 2,4-D has significant health risks of its own. It remains unclear whether continuing low-level di...

Sprayed extensively by the US military in Vietnam, Agent Orange contained a dioxin contaminant later found to be toxic to humans [7]. Despite reports by Vietnamese citizens and Vietnam War veterans of increased rates of stillbirths and birth defects [8] in their children, studies in the 1980s showed conflicting evidence for an association between the two. In 1996, the US National Academy of Sci...

Multiwalled carbon nanotubes were used to modify the surface of a glassy carbon electrode to enhance its electroactivity. Nafion served to immobilise the carbon nanotubes on the electrode surface. The modified electrode was used to develop an analytical method for the analysis of ascorbic acid (AA) by square-wave voltammetry (SWV). The oxidation of ascorbic acid at the modified glassy carbon el...

OBJECTIVE The aim of this study was to evaluate the erosive/abrasive enamel wear after contact with orange juices modified with different dietary supplements. METHODS A total of 96 bovine enamel samples were prepared and allocated to eight groups (1-8; n = 12). Samples were eroded (120 s) in 200 ml of the following eight solutions: 1: water (control), 2: orange juice, 3: water + calcium effer...

dear editor,i read with interest article that published entitled *isolation and identification of bioactive compound producing rhodococcus spp. isolated from soil samples {ijmcm/5(1) (2015) 463-468}* [1]. some of the genus such as nocardia, gordonia, mycobacterium and rhodococcus are in actinomycete family and they are gram-positive and partially acid-fast. rhodococcus species usually stain gra...

Vacuolar pyrophosphatase (V-PPase) from juice cells of 3 citrus varieties (differing in their vacuolar pH) were partially characterized using purified tonoplast vesicles. Total V-PPase activity was highest in vesicle samples from sweet limes with vacuolar pH of 5.0, while samples from acid limes (with lowest vacuolar pH of 2.0) had the minimal total V-PPase activity. Samples from 'Valencia' ora...
