over the past 20 years since tribenuron-methyl herbicide registration in iran, reports of erratic control of broadleaf weeds with it have increased in wheat fields of aq qala. in order to evaluate the incidence of resistance in wild mustard (sinapis arvensis) and turnipweed (rapistrum rugosum) to tribenuron-methyl herbicide, dose-response assays were conducted during the years 1390 and 1391 at ...

BackgroundSkeletal muscle mass (SMM) determined on computed tomography (CT) is emerging as a novel imaging biomarker. Cross-sectional area (CSA) of SMM at the level third lumbar vertebra (L3) abdominal considered clinical reference standard for measuring SMM. In certain patient groups, such those with oncological or non-oncological lung disease like COVID-19, chest CT may be available while an ...

Aim: The present study was undertaken to describe the biotyping of Bacillus cereus isolated from different street vended mutton tikka and chutney samples. Materials and Methods: A total of 100 street vended food samples comprising of 60 mutton tikka and 40 chutney samples were tested. Results: The biotype 3 and biotype 4 showed the highest occurrence with, 29.63% and 25.93% isolates falling in ...

BACKGROUND The cotton-melon aphid, Aphis gossypii Glover (Hemiptera: Aphididae), is a polyphagous species with a worldwide distribution and a variety of biotypes. North China is a traditional agricultural area with abundant winter and summer hosts of A. gossypii. While the life cycles of A. gossypii on different plants have been well studied, those of the biotypes of North China are still uncle...

Cross-infection studies of normal calves infected with homologous pairs of non-cytopathic and cytopathic bovine viral diarrhoea virus (BVDV) showed significant differences in both humoral and cell-mediated immune responses against either biotype over a period of 5 months. Serological assays after primary intranasal inoculation showed striking significant (P < 0.05) differences between biotypes....

vibrio cholerae o1 are classified into two biotypes, classical and el tor based on susceptibility to bacteriophages and some biochemical properties, each encoding a biotype-specific genetic determinants. before 1961, most epidemics had been caused by the classical biotype. however, with the passage of time, the classical biotype missed from the scenario and the el tor emerged as the major bioty...

Triazine-resistant (R) biotypes of several dicot weed biotypes have been shown to differ from triazine-susceptible (S) biotypes both structurally and biochemically. To this point, no R monocot has been examined, however. In this report, we examine the ultrastructure and physiology of three biotypes of Poa annua L.: a S biotype, a R biotype, and a “m ixed” (M) biotype that displays a level of re...

Background and Aim: Gingival biotype is a principal component in restorative and implant procedures, especially in the aesthetic region. Immediate determination of the gingival biotype by the clinician could lead to a more successful outcome, especially during implant placement in the aesthetic zone. The aim of this study was to investigate a possible relationship between gingival biotypes and ...

Four biotypes (pathotypes) of the citrus nematode, Tylenchulus semipenetrans, occurring in California, U.S.A. were differentiated on the basis of differences of infectivity on 'Homosassa' sweet orange, 'Troyer' citrange, 'Pomeroy' and 'Rubidoux' Poncirus trifoliata, 'Thompson Seedless' grape, and 'Manzanillo' olive. A method for differentiating biotypes of T. semipenetrans is described. Field o...

To explore the chemical analogy between thorium and heavier actinides in soft anionic environments, three new thorium phosphides (ThCuP2, β-ThCu2P2, and ThCu5P3) have been prepared through solid-state reactions using CuI as a reaction promoter. The structure of ThCuP2 can be described as a filled UTe2-type with both dimeric P24- and monomeric P3- anions, in which Th is coordinated by eight P at...
