Summary of "The influence of MoO-NPs on agro-morphological criteria, genomic stability of DNA, biochemical assay, and production of common dry bean (Phaseolus vulgaris L.)."

Molybdenum is considered one of the most important micronutrients applied as a foliar fertilizer for common dry bean. In this study, molybdenum oxide nanoparticles (MoO-NPs) were applied in different concentrations (0, 10, 20, 30 and 40 ppm) over two sequent seasons, 2018 and 2019, to investigate their effect on the plant morphological criteria, yield, and the genomic stability of DNA. The results showed that the application of 40 ppm MoO-NPs as a foliar fertilizer showed preferable values of plant morphological criteria, such as the number of leaves and branches per plant, as well as the fresh and dry weight with regard to the common bean plant. In addition, the seed yield increased by 82.4% and 84.1% with 40 ppm, while the shoot residue increased by 32.2% and 32.1% with 20 ppm of MoO-NPs during two seasons, 2018 and 2019, respectively. Furthermore, the common bean treated with 20 and 40 ppm MoO-NPs had positive unique bands with ISSR primer 848 at 1400 bp (Rf 0.519) and with primer ISSR2M at 200 bp (Rf 0.729), respectively. In addition, SDS-PAGE reveald some proteins in seedlings which were absent in the flowering stage at 154, 102, 64, 37 and 34 KDa, which may be due to differences in plant proteins required for metabolic processes in each stage. In conclusion, the application of 40 ppm MoO-NPs was more effective on the productivity of the common bean plants.

Morphological findings useful in differentiation and classification of results in CYTODIAGNOSIS and related techniques.

A screening assay for circulating COMPLEMENT PROTEINS. Diluted SERUM samples are added to antibody-coated ERYTHROCYTES and the percentage of cell lysis is measured. The values are expressed by the so called CH50, in HEMOLYTIC COMPLEMENT units per milliliter, which is the dilution of serum required to lyse 50 percent of the erythrocytes in the assay.

Morphological abnormalities of the cervical EPITHELIUM, usually revealed in PAP SMEAR, which do not meet the criteria for squamous CERVICAL INTRAEPITHELIAL NEOPLASIA or SQUAMOUS CELL CARCINOMAS of the CERVIX . It may be a sign of infection with certain types of human papillomavirus (HPV).or sign of a benign (not cancer) growth, such as a cyst or polyp or, in menopausal women, of low hormone levels. More testing, such as HPV test, may be needed.

Sensitive assay using radiolabeled ANTIGENS to detect specific ANTIBODIES in SERUM. The antigens are allowed to react with the serum and then precipitated using a special reagent such as PROTEIN A sepharose beads. The bound radiolabeled immunoprecipitate is then commonly analyzed by gel electrophoresis. Radioimmunoprecipitation assay (RIPA) is often used as a confirmatory test for diagnosing the presence of HIV ANTIBODIES.
