Six mite species of the family Myobiidae, Radfordia (Austromyobia)persica sp. n., Radfordia (Austromyobia) merioni Bochkov, Dubinina et Chirov, 1990, Radfordia (Radfordia) acomys Fain et Lukoschus, 1977, Radfordia (Radfordia) affinis (Poppe, 1896), Radfordia (Graphiurobia) dyromys Fain et Lukoschus, 1973, and Myobia (Myobia) murismusculi (Schrank, 1781) were found in Iran on the rodents Gerbill...
The chloroform extract of Ferula persica var. persica roots was found to inhibit red pigment production of Serratia marcescens. A bioguided fractionation study by preparative thin layer chromatography (PTLC) detected a fraction (Rf = 0.71, petroleum ether/EtOAc, 2:1 v/v), which was effective on depigmentation of Serratia marcescens. Using conventional spectroscopy methods, the active fraction w...
The genus Rosa L. (Rosaceae) was recently treated floristically for North America, but range extensions and an additional taxon have been confirmed since then and are detailed here. These new reports document range extensions in the US and Canada of some native and introduced Rosa species, and new distributions and population data for several established Rosa hybrids (nothospecies). Some introd...
G. Guzmán, B.A. Latorre, R. Torres, and W.F. Wilcox. 2007. Relative susceptibility of peach rootstocks to crown gall and Phytophthora root and crown rot in Chile. Cien. Inv. Agr. 34(1):31-40. Crown gall (Agrobacterium tumefaciens) and Phytophthora root and crown rot (PRCR), caused by P. cryptogea, are two major limiting factors affecting peach (Prunus persica) production in Chile. At present, N...
The Jaramillo Event was originally defined by Doell and Dalrymple in 1966 on the basis of K^Ar ages from sanidine in the normally, transitionally and reversely magnetized rhyolite domes named Cerro del Abrigo, Cerro Santa Rosa I and Cerro Santa Rosa II, respectively, that erupted following collapse of the archetypal Valles Caldera, New Mexico. We have collected new paleomagnetic data from the t...
Malaria is one of the worldwide parasitic diseases which threaten the life of hundreds of millions of people at the malarious areas each year. The emergence of chloroquine-resistant strains of Plasmodium falciparum in most of the malarious areas has encountered the relevant countries with some difficulties about treating the acute cases of the disease particulary if the monotherapy regimen has ...
In systemic mastocytosis (SM), clinical problems arise from factor-independent proliferation of mast cells (MCs) and the increased release of mediators by MCs, but no human cell line model for studying MC activation in the context of SM is available. We have created a stable stem cell factor (SCF) -dependent human MC line, ROSA(KIT WT), expressing a fully functional immunoglobulin E (IgE) recep...
Rosa centifolia and Rosa gruss an teplitz distillation waste biomass was immobilized using sodium alginate for Pb(II) uptake from aqueous solutions under varied experimental conditions. The maximum Pb(II) adsorption occurred at pH 5. Immobilized rose waste biomasses were modified physically and chemically to enhance Pb(II) removal. The Langmuir sorption isotherm and pseudo-second-order kinetic ...
