Effect of Explant, Type and Concentration Hormone on Callus Induction Regeneration two Iranian Sesame (Sesamum indicum L.) Cultivars

OBJECTIVES Clinical trials of spinal cord stimulation (SCS) have largely focused on conversion from trial to permanent SCS and the first years after implant. This study evaluates the association of type of SCS and patient characteristics with longer-term therapy-related explants. MATERIALS AND METHODS Implanting centers in three European countries conducted a retrospective chart review of SCS...

Micropropagation of Kainth using nodal explants was carried out in tissue culture laboratory, Department of Fruit Science, Punjab Agricultural University, Ludhiana during 2011-13. The effect of various media {1/2 MS (M1), MS (M2) and WPM (M3)} and growth regulators (BAP, IBA and NAA) on establishment, proliferation and rooting was studied. Per cent necrotic culture was found to be influenced by...

A complete protocol is presented for in vitro regeneration of pomegranate (Punica granatum L.), a tropical fruit tree, using cotyledonary nodes derived from axenic seedlings. Shoot development was induced from cotyledonary nodes on Murashige and Skoog (1962) (MS) medium supplemented with 2.3±23.0 mM benzyladenine (BA) or kinetin (Kn). Both type and concentration of cytokinin signi®cantly in ̄uen...

An in vitro steroidogenesis assay using H295R human adenocarcinoma cells has been suggested as a possible alternative to gonad explant assays for use as a Tier I screening assay to detect endocrine active chemicals capable of modulating steroid hormone synthesis. This study is one of the first to investigate the utility of the H295R assay for predicting effects and/or understanding mechanisms o...

AIM To determine the immunohistochemical characteristics of putative corneal epithelial stem cells remaining on limbal explants maintained in culture. METHODS Human limbal explant cultures were generated from 25 residual corneoscleral donor rims following penetrating keratoplasty. Serial sections of these explants were studied using immunohistochemical techniques with a panel of antibodies, o...

Purpose: Rauwolfia serpentina (L.) Benth, from the family, Apocynaceae, is an important medicinal plant due to the alkaloid content of its root. The purpose of this study was to obtain roots directly from leaf explant using growth regulators. Methods: The leaf explant was inoculated on MS (Murashige and Skoog) medium supplemented with single and combinations of growth regulators. Root growth wa...

The rheumatoid arthritis (RA) joint is characterized by an inflammatory synovial pannus which mediates tissue destruction. IL-13 is a cytokine that inhibits activated monocytes/macrophages from secreting a variety of proinflammatory molecules. The aim of this study was to examine whether gene therapy-delivered IL-13 could reduce the production of key proinflammatory mediators in RA synovial tis...

During chicken cardiac development the proepicardium (PE) forms the epicardium (Epi), which contributes to several non-myocardial lineages within the heart. In contrast to Epi-explant cultures, PE explants can differentiate into a cardiomyocyte phenotype. By temporal microarray expression profiles of PE-explant cultures and maturing Epi cells, we identified genes specifically associated with di...
