    Abstract Purpose: Standard cytotoxic induction chemotherapy for acute myeloid leukemia (AML) results in prolonged neutropenia and risk of infection. Romyelocel-L is a universal, allogeneic myeloid progenitor cell product being studied to reduce infection during induction chemotherapy.
    Patients and methods: One hundred sixty-three patients with de novo AML (age ≥ 55 years) receiving induction chemotherapy were randomly assigned on day 0 (d0), of whom 120 were evaluable. Subjects received either romyelocel-L infusion on d9 with granulocyte colony-stimulating factor (G-CSF) starting daily d14 (treatment group) or G-CSF daily alone on d14 (control) until absolute neutrophil count recovery to 500/µL. End points included days in febrile episode, microbiologically defined infections, clinically diagnosed infection, and days in hospital.
    Results: Mean days in febrile episode was shorter in the treatment arm from d15 through d28 (2.36
    Conclusion: Subjects receiving romyelocel-L showed a decreased incidence of infections, antimicrobial use, and hospitalization, suggesting that romyelocel-L may provide a new option to reduce infections in patients with AML undergoing induction therapy.

    Abstract: ... plants. One-year-old olive plants (cv Chemlali) irrigated with a saline water (10g/L) were subjected ...

    Abstract Purpose: Nowadays with the precipitation scarcity induced by climate change, the use of non-conventional water resources in irrigation is needed such as saline water. The irrigation of salt tolerance species like olive could be adopted with potassium foliar spray. In this work we present how olive plants modulate sodium potassium balance and metabolism to mitigate salt stress. Research method: A pot experiment was conducted to assess how potassium nitrate modify Na/K ratio and biochemical compounds in olive plants. One-year-old olive plants (cv Chemlali) irrigated with a saline water (10g/L) were subjected to three treatments: K0, K1 and K2 (0, 1 and 2% of potassium nitrate foliar spray, respectively). Findings: Results showed differences between treatments. The mineral composition particularly the sodium and potassium content of leaves and roots revealed that the K1 and K2 treatments slightly increased K/Na in leaves and decreased in roots. Moreover, the salt stress was moderate through the osmotic adjustment. The accumulation of osmolytes (proline and soluble sugars) decreased by k1 and K2 treatments. Secondry metabolites (phenols) showed an increase by K1 and K2. Lipid peroxydation was also reduced by treatments especially in young leaves and then increased. In conclusion, potassium can be recommended in order to mitigate the harmful effects of salinity. Research limitations: No limitations were founded. Originality/Value: In the condition of current water scarcity the saline water could be used with potassium application.

    Abstract Changes in the plant water status, biochemical and hormonal responses, were investigated in three olive cultivars (Arbequina, Arbosana and Chetoui) grown in a super-high-density orchard under partial root-zone drying (PRD) irrigation. Four irrigation treatments were applied during two growing seasons (2015 and 2016); control treatment (100 % ETc) irrigated at 100 % of crop evapotranspiration on both parts of the root-zone and three PRD irrigation treatments (100 % PRD, 75 % PRD and 50 % PRD) irrigated at 100 %, 75 %, and 50 % of crop evapotranspiration only on one alternated part of the root-zone. The results indicated that the three studied olive cultivars showed a clear difference in their response to PRD irrigation. Arbequina cultivar has shown a conservative strategy for using water since relative water content (RWC) and stem water potential (Ψₛₜₑₘ) were reduced more in Arbosana and Chetoui under PRD irrigation. In fact, PRD irrigation has led to a strong activation of secondary metabolites with antioxidant properties such as pigments, phenols and flavonoids. Other metabolic changes, including the accumulation of soluble sugars and proline have been also triggered by PRD irrigation. Among the studied cultivars, Arbequina displayed the highest levels of proline, total soluble sugars, phenols and flavonoids, and the lowest ones for Malondialdehyde (MDA) and hydrogen peroxide (H₂O₂).The increase in Superoxide dismutase (SOD), catalase (CAT) and guaiacol peroxidase (POD) activity and the reduction in polyphenoloxidase (PPO) activity under PRD irrigation were more pronounced in 2016 season with highest activities obtained from cultivar Arbequina.For all the three cultivars, PRD irrigation increased phytohormones concentration in both, roots and leaves and the highest levels were recorded in 2016. In leaves, Arbequina showed the lowest levels of abscisic acid (ABA), and the highest levels of jasmonic acid (JA), salicylic acid (SA) and indole-3-acetic acid (IAA). PRD irrigation also induces a higher accumulation of ABA, JA and IAA in dried roots than in wetted ones.Taken together, physiological and biochemical mechanisms induced by PRD irrigation were more effective in Arbequina suggesting better protection of their foliar functions compared to other cultivars and its higher adaptability to PRD.

    Abstract Objective: The aim of this study was to determine whether oral supplementation with L-glutamine (GLN) modifies the gut microbiota composition in overweight and obese adults.
    Methods: Thirty-three overweight and obese adults, ages between 23 and 59 y and body mass index between 25.03 and 47.12 kg/m(2), were randomly assigned to receive either oral supplementation with 30 g of L-alanine (ALA group control) or 30 g of GLN (GLN group) daily for 14 d. We analyzed the gut microbiota composition with new-generation sequencing techniques and bioinformatics analysis.
    Results: After 14 d of supplementation, adults in the GLN group exhibited statistically significant differences in the Firmicutes and Actinobacteria phyla compared with those in the ALA group. The ratio of Firmicutes to Bacteroidetes, a good biomarker for obesity, decreased in the GLN group from 0.85 to 0.57, whereas it increased from 0.91 to 1.12 in the ALA group. At the genus level, Dialister, Dorea, Pseudobutyrivibrio, and Veillonella, belonging to the Firmicutes phylum, had statistically significant reduction.
    Conclusion: Oral supplementation with GLN, for a short time, altered the composition of the gut microbiota in overweight and obese humans reducing the Firmicutes to Bacteroidetes ratio, which resembled weight loss programs already seen in the literature.

    Abstract: ... of the type X–Au–L [X = Cl, Br, I; L = CNᵗBu, CNMe, PMe₃, P(NMe₂)₃, P(OCH₂CF₃)â ...

    Abstract Trends in volatility with changes in the halide ligand were established for gold(I) complexes of the type X–Au–L [X = Cl, Br, I; L = CNᵗBu, CNMe, PMe₃, P(NMe₂)₃, P(OCH₂CF₃)₃] by determining the temperatures for the onset of sublimation (Tₛᵤb) at a fixed pressure. Within each series of isocyanide complexes, Tₛᵤb decreases with increasing atomic radius of the halide, making the iodide complex the most volatile. For the phosphine and phosphoramidate complexes, the chloride and bromide have similar Tₛᵤb values with the bromide slightly higher, but the iodide complex is again the most volatile of the three. The trends in volatility can be correlated to variation in Au–Au bond distances and aggregation patterns in the solid state structures. For the P(OCH₂CF₃)₃ complexes, melting occurred before sublimation, but the iodide complex was still more volatile than the bromide. These trends have implications for the use of these complexes in electron beam induced deposition and chemical vapor deposition, for which precursor volatility is important.

    Abstract The Jatropha curcas, known as physic nut, belonging to the Euphorbiaceae family, figure today as one of the greatest potential of oilseeds for biodiesel production in Brazil. The present study aimed to evaluate meiosis and pollen viability in J. curcas accesses from UFRRJ germplasm collection. To do that, flower buds were collected from 20 plants, these were fixed in acetic acid 3:1 solution and alcohol 70%. The staining of the cells was done by acetic carmine 2% solution and Alexander’s triple solution, for the analysis of meiotic and pollen viability, respectively. All observations were carried out under an optical microscope. It was observed that the species has 2n = 2x = 22 chromosomes. It was observed many irregularities during the meiotic division as the presence of sticky chromosomes and irregular meiotic products, such as monads, dyads, triads and polyads, and the occurrence of cytomixis and micronucleus, these latter two anomalies had a higher frequency among the accessions. The meiotic index was estimated in 84.21% and the average pollen viability in 89.85%. The lowest pollen viability was 78% (UFRRJ885), while the maximum observed was 96% (UFRRJ861). Based on the results obtained, although Jatropha curcas presents certain anomalies during meiosis, the accessions analyzed here showed satisfactory pollen viability.

    Abstract Maize (Zea mays L.) biomass and its allied attributes were assessed under salinity stress and three plant growthpromoting rhizobacteria (Pseudomonas fluorescens, Pseudomonas putida and Azotobacter vinelandii) treatments. The three PGPRs inocula exhibited a different pattern of shoot growth under both normal and saline stress conditions. Plant biomass, carbohydrates, protein and chlorophyll content were reduced by saline stress, however application of PGPRs treatments improved them either in comparison to control samples or to untreated samples under saline stress. Lipids and antioxidant enzymes (catalase and peroxidase) increased as a response for saline stress as an indication of oxidative stress. Plant growth-promoting rhizobacteria treatment restored them to semi-normal levels. Sodium/ potassium balance was observed to be disturbed by saline stress through higher levels of Na+ and lower levels of K+, but treating samples balance was clearly restored close to normal conditions especially in the root system.
