Abstract
Ten medicinal plants used as ingredients of folklore and Ayurvedic medicine belonging to the Malnad Kerala region of South India, were analysed for concentrations of trace elements Fe, Cr, Mn, Co, Ni, Cu, Zn, As, and Pb using the Energy Dispersive X-ray Fluorescence (EDXRF) technique. The soil from the root area of these medicinal plants was also analysed, and the soil to plant transfer factor (TF) of the elements was estimated. Iron (Fe) recorded higher concentration than the other trace elements estimated in the medicinal plants, followed by manganese (Mn) and zinc (Zn). The mean TF was found to be highest for Zn.Plectranthus amboinicus(Lour.) Spreng recorded the maximum value of TF for Zn. Most of the essential elements were found to be present inCentella asiatica(L.) Urban and indicated its medicinal importance. The data obtained in the present investigation may add up to the trace elemental database of medicinal plants in the world.

Abstract
Background: The clinical efficacy and safety of transradial (TR) percutaneous coronary intervention (PCI) in comparison to transfemoral (TF) for chronic total occlusion (CTO) is not well studied in literature. Objectives: We sought to study the outcome and complications associated with TR compared with TF for CTO interventions. Methods: After a systematic literature search was done in PubMed and EMBASE, we performed a meta-analysis of studies comparing TF and TR for CTO PCI. Results: Twelve studies with 19,309 patients were included. Compared to those who has TF access, individuals who were treated via TR approach had statistically significant lower access complication rates [odds ratio (OR): 0.33; 95% confidence interval (CI): 0.22 to 0.49; p < 0.0001]. The procedural success was in the favor of TR method (OR: 1.4; 95% CI: 1.31-1. 51; p < 0.0001). The incidence of major adverse cardiovascular and cerebrovascular events (MACCE) and contrast-induced nephropathy were similar in both groups. Conclusion: When compared with TF access interventions in CTO PCI; the TR approach appears to be associated with far less access-site complications, higher procedural success, and comparable MACCE.
