Abstract
A robust biocompatible solid-phase microextraction (SPME) fiber, so-called Ti/APTS/GA/CS, was prepared by chemical bonding of cross-linked glutaraldehyde-chitosan to the surface of a titanium wire using APTS. The fiber was applied for sampling of phytohormones in plant tissues, followed by HPLC-UV analysis. The structure and morphology of the fiber coating was investigated by FT-IR, SEM, EDX, XRD, and TGA techniques. A Box-Behnken design was implemented to optimize the experimental variables. The calibration graphs were linear over a wide linear range (0.5-200 μg L-1) with LODs over the range of 0.01-0.06 μg L-1. The intra-day and inter-day precisions were found to be 1.3-6.3% and 4.3-7.3%, respectively. The matrix effect values ranged from 86.5% to 111.7%, indicating that the complex sample matrices had an insignificant effect on the determination of phytohormones. The fiber was successfully employed for the direct-immersion SPME (DI-SPME-HPLC) analysis of the phytohormones in cucumber, tomato, date palm, and calendula samples.

Abstract
Banana harvesting generates a large amount of banana pseudostem waste, which is generally burnt or thrown away, despite containing many nutrients. Bio-enriched organic fertilizer (BOF) was prepared from banana pseudostem sap (BPS), and it has been patented (Patent No. WO 2013/001478 Al). Several reports revealed that its application increases plant growth promotion of various horticulture crops. Apart from macro- and micronutrients, it also contained phytohormones. Hence, the present study aims to detect and quantify phytohormone in it. A novel method was developed to extract four phytohormones, viz., indole-3-acetic acid (IAA), indole-3-butyric acid (IBA), gibberellic acid (GA3), and salicylic acid (SA) using single solvent from BPS and BOF. Extracted hormones were analyzed by ultrahigh-performance liquid chromatography coupled with heated electrospray ionization tandem mass spectrometry (UHPLC-HESI-MS/MS). BOF showed a higher concentration of IAA, IBA, GA3, and SA than BPS. Thus, this is the first time a method has been reported to extract and detect phytohormones from banana pseudostem sap.

Abstract
ABSTRACT Organ injury by oxidative and inflammatory mediators occurs during ischemia-reperfusion (I/R) of the liver. Remote organ injury secondary to liver I/R increases the systemic insult. Tender coconut water (TCW) has been studied in chemical and fructose-induced liver injury but its ability to decrease tissue injury in clinically relevant injury models is unknown. We evaluated the therapeutic potential of TCW in preventing liver I/R injury and associated remote organ injury. Mice were fed sugar water (SUG; control) or TCW for a week and then subjected to 60 min of liver ischemia followed by reperfusion for 6 h. Plasma alanine transaminase levels, tissue damage, and mRNA levels of Nos2, Tnf, and Il6 were significantly lower in mice fed TCW prior to I/R. Plasma cytokines followed liver cytokine patterns. TCW increased mRNA levels of the anti-oxidant genes Hmox1 and Ptgs2 in the liver of mice subjected to I/R. Remote lung injury from liver I/R was also decreased by TCW feeding as evident by less neutrophil infiltration, decreased pro-inflammatory Il6, and increased anti-inflammatory Il10 mRNA levels in the lung. To examine macrophage activation as a potential mechanism, TCW pretreatment decreased the amount of nitrite produced by RAW264.7 macrophages stimulated with LPS. The levels of Nos2, Il1b, Tnf, and Il6 were decreased while Il10 and Hmox1 mRNA levels were significantly up-regulated upon LPS stimulation of TCW pretreated RAW264.7 macrophages. Collectively, our results indicate that TCW decreased hepatic I/R-mediated damage to liver and lung and suggest that decreased macrophage activation contributes to this effect.

Abstract
Background Terrestrial orchids belonging to the Orchis genus are difficult to propagate and are under great pressure in their natural habitats. Studies regarding the influence of photoperiod and temperature regimes on Orchis militaris germination and morphological changes during immature seed development in vitro are scarce. Our aim was to identify photoperiod, temperature, and different nutrient media requirements for optimization of O. militaris seed germination and vigorous seedling production. Results Post-germination morphological changes were recorded with O. militaris seeds collected from 32-day-old fruits, where the percentage of O. militaris seeds without embryo was 38.4%. The highest rate of O. militaris seed germination (82.6%) was obtained on Malmgren modified terrestrial orchid medium (mM), enriched by 5% coconut water, 5% birch sap, and 0.1% AC. Nine percent of seedlings were able to reach the advanced seedling stage (stage 6) after 12 months of maintenance on this medium. In all 3 modified media (Harvais, Knudson С and Malmgren), regeneration was via the production of protocorms and seedlings without callus formation. It was proved that more abundantly vigorous protocorms were formed on the modified Harvais 2 under continuous darkness, while the subculture in Knudson C medium with AC addition could be necessary to stimulate their further development. The regeneration success of the species for in vitro conditions was increased by following its natural seasonal cycle. Conclusion This study demonstrated an efficient micropropagation system for O. militaris using immature seeds and thus widely opened the perspectives for its conservation in nature. The favorable conditions of seed germination periods for in vitro culture, identified as the definite shift of temperatures and photoperiod regimes intrinsic to the species in nature, could improve seedling survival of this medicinally important orchid.

Abstract
Gibberellins, as a group of phytohormones, exhibit a wide variety of bio-functions within plant growth and development, which have been used to increase crop yields. Many analytical procedures, therefore, have been developed for the determination of the types and levels of endogenous and exogenous gibberellins. As plant tissues contain gibberellins in trace amounts (usually at the level of nanogram per gram fresh weight or even lower), the sample pre-treatment steps (extraction, pre-concentration, and purification) for gibberellins are reviewed in details. The primary focus of this comprehensive review is on the various analytical methods designed to meet the requirements for gibberellins analyses in complex matrices with particular emphasis on high-throughput analytical methods, such as gas chromatography, liquid chromatography, and capillary electrophoresis, mostly combined with mass spectrometry. The advantages and drawbacks of the each described analytical method are discussed. The overall aim of this review is to provide a comprehensive and critical view on the different analytical methods nowadays employed to analyze gibberellins in complex sample matrices and their foreseeable trends.
