45S RDNA REGIONS ARE CHROMOSOME FRAGILE SITES EXPRESSED AS GAPS IN VITRO ON METAPHASE CHROMOSOMES OF ROOT-TIP MERISTEMATIC CELLS IN LOLIUM SPP.

45S rDNA regions are chromosome fragile sites expressed as gaps in vitro on metaphase chromosomes of root-tip meristematic cells in Lolium spp.

BackgroundIn humans, chromosome fragile sites are regions that are especially prone to forming non-staining gaps, constrictions or breaks in one or both of the chromatids on metaphase chromosomes either spontaneously or following partial inhibition of DNA synthesis and have been well identified.So far, Accessories no plant chromosome fragile sites

Potential Gonado-Protective Effect of Cichorium endivia and Its Major Phenolic Acids against Methotrexate-Induced Testicular Injury in Mice

Cichorium endivia L.(Asteraceae) is a wide edible plant that grows in the Mediterranean region.In this study, a phytochemical investigation of C.endivia L.ethanolic extract led to the isolation of stigmasterol (1), ursolic acid (2), β-amyrin (3), azelaic acid (4), vanillic acid (5), (6S, 7E)-6-hydroxy-4,7-megastigmadien-3,9-dione (S(+)-dehydrovomi

A Cost-free Alternative Approach to Simulation of Pressure Transient Response for Slightly Compressible Fluids

Generating pressure transient response for Kelp an interpretation model to describe essential features of a reservoir system accurately is often difficult.It is generally due to the inaccessibility of standard pressure transient analysis tools due to the cost, and even when accessible, they are constrained to its workflow and limitations.This study

Therapeutic strategies in pulmonary hypertension

Pulmonary hypertension (PH) is a life-threatening condition characterized by elevated pulmonary arterial pressure.It is clinically classified into five groups: patients in the first group are considered to have pulmonary arterial hypertension (PAH) whereas patients of the other groups have PH that is due to cardiopulmonary or other systemic disease
