The biochemical characteristics of 464 strains of Haemophilus influenzae and 83 strains of Haemophilus parainfluenzae isolated over an 18-month period are described. Of 22 characteristics obtained, only 6 were necessary to biochemically identify and biotype the isolates. The key substrates or tests were urease, ornithine, indole, o-nitrophenyl-beta-D-galactopyranoside, sucrose, and xylose. Five...

Human-mediated bioinvasions provide the opportunity to study the early stages of contact between formerly allopatric, divergent populations of a species. However, when invasive and resident populations are morphologically similar, it may be very difficult to assess their distribution in the field, as well as the extent of ecological overlap and genetic exchanges between invasive and resident po...

Three diclofop-methyl (DM) resistant biotypes of Lolium rigidum (R1, R2, and R3) were found in different winter wheat fields in Spain, continuously treated with DM, DM + chlortoluron, or DM + isoproturon. Herbicide rates that inhibited shoot growth by 50% (ED50) were determined for DM. There were found that the different biotypes exhibited different ranges of resistance to this herbicide; the r...

two separate greenhouse experiments were conducted in the greenhouse of the iranian plant protection research institute, tehran, to compare the efficacy of some acetyl coa carboxylase (accase) and acetolactase synthase (als) inhibiting herbicides in control of wild oat biotypes. in each experiment, populations were independently treated by 10 herbicides each in 12 replications. to evaluate the ...

During treatment planning it is important to recognize different gingival biotypes and forms, because they can affect the esthetic outcome of the treatment. This review provides an insight into the different gingival biotypes, their response to inflammation and trauma; significance in different prosthodontic modalities like esthetic rehabilitation and implant therapy.

Background Amaranthus hybridus, a common agricultural weed in Brazil, has been associated with complications the management of major crops. Recently, A. hybridus biotypes suspected resistance to herbicide glyphosate have observed state Paraná. Objective To characterize glyphosate-resistant biotypes. Methods Three independent experiments were conducted evaluate four hybridus. Twelve doses applie...

Emerging T-helper type 2 (Th2 ) cytokine-based asthma therapies, such as tralokinumab, lebrikizumab (anti-interleukin (IL)-13), and mepolizumab (anti-IL-5), have shown differences in their blood eosinophil (EOS) response. To better understand these effects, we developed a mathematical model of EOS dynamics. For the anti-IL-13 therapies, lebrikizumab and tralokinumab, the model predicted an incr...

ABSTRACT. The present study describes synthesis of some new luminol derivatives, which might play an important role in biological active agents. These synthesized compounds are functionalized based on (LM) with different carboxylic drugs such as mefenamic acid, ibuprofen, diclofenac sodium, and ampicillin). Synthesis processes was conducted by converting group the investigated into acid chlorid...

Representational difference analysis (RDA) is a recently developed technique used for amplifying genetic differences between two closely related genomes. We compared RDA and a modified version of RDA to examine genomic differences between the two Vibrio cholerae serogroups that cause epidemic cholera, O1 and O139, and between the two biotypes of the O1 serogroup. With both techniques, we recove...
