Abstract

Rutin, a flavonoid phytochemical compound, plays a vital role in human health. It is used in treating capillary fragility and has anti-Alzheimer, anti-inflammatory, and antioxidant effects. In this study, Ti-Mo-Ni-O nanotubes (NTs) were used, for the first time, in an unprecedented plant biotechnology application, wherein in vitro Philodendron shoots (Philodendron erubescens) known as "Imperial Red" were targeted for rutin accumulation. The antioxidant responses and the accumulation of rutin were evaluated in treated Philodendron erubescens (P. erubescens) shoots using 5.0 mg/L of Ti-Mo-Ni-O NTs. The total phenolic content and total flavonoid content were estimated, and an ABTS+ assay, FRAP assay, and iron metal chelation assay were performed. The application of Ti-Mo-Ni-O NTs enhanced the rutin content considerably from 0.02 mg/g to 2.96 mg/g for dry-weight shootlet extracts. Therefore, the use of Ti-Mo-Ni-O NTs is proposed to be a superior alternative to elevate the rutin content. The aim of the current study is to target P. erubescens shoots grown in vitro for the accumulation of rutin compounds using Ti-Mo-Ni-O NT powder, to determine the quantitative and qualitative accumulation of rutin via HPLC–DAD analysis, and to estimate the antioxidant activity of P. erubescens shoot extract. This study presents a novel methodology for utilizing nano-biotechnology in the synthesis of plant secondary metabolites. [ABSTRACT FROM AUTHOR]

34. The impact of hospital presentation time on stroke outcomes: A nationally representative Irish cohort study.

Abstract

Objectives: There is conflicting evidence regarding the outcomes of acute stroke patients who present to hospital within normal working hours ('in-hours') compared with the 'out-of-hours' period. This study aimed to assess the effect of time of stroke presentation on outcomes within the Irish context, to inform national stroke service delivery. Materials and methods: A secondary analysis of data from the Irish National Audit of Stroke (INAS) from Jan 2016 to Dec 2019 was carried out. Patient and process outcomes were assessed for patients presenting 'in-hours' (8:00–17:00 Monday-Friday) compared with 'out-of-hours' (all other times). Results: Data on arrival time were available for 13,996 patients (male 56.2%; mean age 72.5 years), of which 55.7% presented 'out-of-hours'. In hospital mortality was significantly lower among those admitted 'in-hours' (11.3%, n = 534) compared with 'out-of-hours' (12.8%, n = 749); (adjusted Odds Ratio (OR) 0.82; 95% Confidence Interval CI [95% CI] 0.72–0.89). Poor functional outcome at discharge (Modified Rankin Scale ≥ 3) was also significantly lower in those presenting 'in-hours' (adjusted OR 0.79; 95% CI 0.68–0.91). In patients receiving thrombolysis, mean door to needle time was shorter for 'in-hours' presentation at 55.8 mins (n = 562; SD 35.43 mins), compared with 'out-of-hours' presentation at 80.5 mins (n = 736; SD 38.55 mins, p <.001). Conclusion: More than half of stroke patients in Ireland present 'out-of-hours' and these presentations are associated with a higher mortality and a lower odds of functional independence at discharge. It is imperative that stroke pathways consider the 24 hour period to ensure the delivery of effective stroke care, and modification of 'out-of-hours' stroke care is required to improve overall outcomes.

50. Cryopreservation of date palm tissue cultures by vitrification and assessment of genetic stability using ISSR analysis.

Abstract

In this work, a successful cryopreservation method of date palm tissue cultures by vitrification was established. Callus and somatic embryos of three date palm cultivars were exposed to dimethylsulfoxide (DMSO) and Plant Vitrification Solution 2 (PVS2) for different durations before plunging into liquid nitrogen for cryoprotection. After freezing phase, the cryopreserved cultures were thawed and cultured on recovery media. Among different times of exposure to DMSO (10%), 60 min gave best results of survival and regrowth of the date palm tissue cultures. Regarding recovery, 'Zaghlool' cultivar gave the highest values of callus fresh mass (0.5 g) and growth value (1.00). Also, the highest differentiation percentages (75%) and number of proliferated shootlets (8.50) were recorded with 'Zaghlool' cultivar. Concerning PVS2, survival and regrowth gradually increased as exposure time increasing till 30 min and then decreased. Unlike of callus cultures, the survival and regrowth rates of somatic embryos were relatively higher at all PVS2 exposure time. With regard to recovery, the genotype effect took same trend in cryopreservation of callus cultures, since 'Zaghlool' was superior in growth parameters in comparison to the other two cultivars. On the other hand, genetic stability of the cryopreserved date palm tissue cultures was assessed using ISSR markers. Among four screened primers, three gave monomorphic bands; all of these banding profiles were similar to those of noncryopreserved cultures. Generally, the results of ISSR showed high genetic similarity suggesting that cryopreservation using vitrification does not affect genetic stability of date palm tissue cultures. The results of this study demonstrated PVS2 was more effective in cryoprotection of date palm tissue cultures compared with DMSO and cryopreservation by vitrification is a suitable tool for conservation of genetic stable date palm germplasm.
