this study aimed to assess the effect of chloroform, eucalyptol and orange oil solvents on the microhardness of human root dentin.sixty-eight single-rooted single-canal extracted human premolar teeth were used. tooth crowns were separated from the roots at the cementoenamel junction (cej). roots were buccolingually sectioned into mesial and distal halves. specimens were randomly divided into 5 ...

PURPOSE The aim of this study was to evaluate the accuracy of ORange(®) Gen II (WaveTec Vision, Aliso Viejo, CA). SETTING The Surgical Suites, Honolulu, HI. METHODS The prospective 28 consecutive cataract surgical cases were selected from 85 cataract surgical cases between December 16, 2010 and February 24, 2011. With the same intraocular lens implantation, the predicted spherical equivalen...

The biology of the citrus psyllid Diaphorina citri Kuwayama was studied at 258C on four commonly grown citrus and related plants [rough lemon, Citrus jambhiri Lush; sour orange, C. aurantiumL.; grapefruit,C.paradisiMacfadyen; andorange jessamine,Murrayapaniculata(L.) Jack] in the laboratory. The biological characteristics of each life stage are described. The average egg incubation periods on o...

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...

Accelerated bleaching and photobleaching of diluted solutions of Methyl Orange and other dyes occur only when Co2+-ions are present in solution mediating oxone (2KHSO5·KHSO4·K2SO4) decomposition. The bleaching of Methyl Orange, Orange II and Methylene Blue dyes in dilute solutions (0.01 mM) proceeds within a few minutes and occurs at biocompatible pH leading to a decrease in the toxicity of the...

Dichlorvos (dimethyl 2,2-dichlorovinyl phosphate) inhibits the biosynthesis of aflatoxin by Aspergillus parasiticus. Cultures treated with dichlorvos excrete an orange pigment which can be converted into aflatoxin B(1) by the untreated mycelia. The orange pigment was partially identified as an acetyl derivative of versiconol-type compound. In the presence of dichlorvos, sterigmatocystin is conv...

Local guilds define groups of species that share common resources and coexist in space and time. Local guilds have historically been a major focus of community ecology; however, studies of local guilds rarely measure consequences of coexistence for fitness-related traits or test predictions of alternative hypotheses for how species may interact. We studied consequences of coexistence for Orange...

Phototoxic fluorescent proteins represent a sparse group of genetically encoded photosensitizers that could be used for precise light-induced inactivation of target proteins, DNA damage, and cell killing. Only two such GFP-based fluorescent proteins (FPs), KillerRed and its monomeric variant SuperNova, were described up to date. Here, we present a crystallographic study of their two orange succ...
