    Abstract - Hemodynamic changes and cardiac arrhythmias are not uncommon in clinical practice, depending on including patient features, surgical treatment and drugs administered. We describe hemodynamic changes developed in young patients, soon after a local infiltration anesthesia in day surgery. Methods - We retrospectively assessed the hemodynamic effect of 2% lidocaine with 0,0125mg/ml adrenaline (Li & AD) administered for septorhinoplasty in 44 participants and combination of 0.5% bupivacaine and 2% lidocaine with 0.0125mg/ml adrenaline (BLi & AD) for breast augmentation in 48 participants. Blood pressure and heart rate were recorded before the introduction of general anesthesia, immediately 5.10 and 20 minutes after administration of local infiltration, anesthetic (LIA) and data were analyzed. Results - The mean systolic blood pressure (SBP) in all observed measurements before general anesthesia (0), immediately, 5 minutes, 10 minutes and 20 minutes after local infiltration anesthesia was higher among patients who underwent septorinoplasty (Li & AD), in relation to patients who underwent breast augmentation (BLi & AD) (p <05). The level of diastolic blood pressure (DBP) in measurement 20 minutes compared to measurement in 10 minutes was increased by 9,52 mmHg. The septorhinoplasty group showed a significant increase in heart rate measured 20 minutes after local infiltration anesthesia with adrenaline. Conclusions - Measured transitory changes in heart rate and blood pressure after local infiltration of vasoconstrictor anesthetics in healthy patients prior to septorinoplasty and breast augmentation may be induced by endogenous and / or exogenous epinephrine. Bupivacaine solution for local infiltration analgesia reduces hemodynamic disturbances and prolongs analgesic effect. We highlight the need for careful preoperative evaluation, including anxiety assessment and treatment in all patients in day surgery.Sažetak Hemodinamske promjene i aritmije srca nisu rijetkost u kliničkoj praksi, ovisne o osobinama bolesnika, kirurškom liječenju i primijenjenim lijekovima. Opisane su hemodinamske promjene koje su se razvile u mlađih bolesnika ubrzo nakon lokalne infiltracije anestezija u dnevnoj kirurgiji Metode Retrospektivno smo procijenili hemodinamski učinak 2% lidokaina s 0,0125 mg/ml adrenalina (Li & AD) primijenjenog za septorinoplastiku u 44 pacijenta i kombinacija od 0,5% bupivakaina i 2% lidokaina s 0,0125 mg/ml adrenalina (BLi & AD) za povećanje dojki u 48 sudionika. Krvni tlak i broj otkucaja srca bilježeni su prije uvoda u opću anesteziju 0, te poslije 5,10 i 20 minuta nakon primjene lokalne infiltracije anestetika (LIA) i podaci su analizirani. Rezultati Srednja vrijednost sistoličkog krvnog tlaka (SRR) u svim promatranim mjerenjima prije opće anestezije (0), odmah 5 minuta, 10 minuta i 20 minuta nakon lokalne infiltracije anestetika bila je viša kod pacijenata podvrgnutih septorinoplastici (Li & AD) u odnosu na pacijentice podvrgnute povećanju dojki, (BLi & AD) skupina (p <05). Vrijednosti dijastoličkog tlaka (DRR) 20 minuta u odnosu na 10 minuta povećane su za 9,52 mmHg(P<0.05). Pacijenti podvrgnuti septorinoplastici imali su značajan porast srčane frekvencije u 20 minuti nakon lokalne infiltracije anestetika s adrenalinom. Zaključci: Izmjerene prolazne promjene otkucaja srca i krvnog tlaka nakon lokalne infiltracije anestetika s vazokonstriktorima u zdravih pacijentica prije septorinoplastike i povećanja grudi mogu biti potaknute endogenim i/ili egzogenim adrenalinom. Bupivakain otopina za lokalnu infiltracijsku analgeziju smanjila je hemodinamske poremećaje i produžila analgetski učinak. Ističemo potrebu za pažljivom preoperativnom evaluacijom, uključujući procjenu anksioznosti i liječenje u svih pacijenata u dnevnoj kirurgiji

    A Novel fry1 Allele Reveals the Existence of a Mutant Phenotype Unrelated to 5′->3′ Exoribonuclease (XRN) Activities in Arabidopsis thaliana Roots

    BACKGROUND Mutations in the FRY1/SAL1 Arabidopsis locus are highly pleiotropic, affecting drought tolerance, leaf shape and root growth. FRY1 encodes a nucleotide phosphatase that in vitro has inositol polyphosphate 1-phosphatase and 3',(2'),5'-bisphosphate nucleotide phosphatase activities. It is not clear which activity mediates each of the diverse biological functions of FRY1 in planta. PRINCIPAL FINDINGS A fry1 mutant was identified in a genetic screen for Arabidopsis mutants deregulated in the expression of Pi High affinity Transporter 1;4 (PHT1;4). Histological analysis revealed that, in roots, FRY1 expression was restricted to the stele and meristems. The fry1 mutant displayed an altered root architecture phenotype and an increased drought tolerance. All of the phenotypes analyzed were complemented with the AHL gene encoding a protein that converts 3'-polyadenosine 5'-phosphate (PAP) into AMP and Pi. PAP is known to inhibit exoribonucleases (XRN) in vitro. Accordingly, an xrn triple mutant with mutations in all three XRNs shared the fry1 drought tolerance and root architecture phenotypes. Interestingly these two traits were also complemented by grafting, revealing that drought tolerance was primarily conferred by the rosette and that the root architecture can be complemented by long-distance regulation derived from leaves. By contrast, PHT1 expression was not altered in xrn mutants or in grafting experiments. Thus, PHT1 up-regulation probably resulted from a local depletion of Pi in the fry1 stele. This hypothesis is supported by the identification of other genes modulated by Pi deficiency in the stele, which are found induced in a fry1 background. CONCLUSIONS/SIGNIFICANCE Our results indicate that the 3',(2'),5'-bisphosphate nucleotide phosphatase activity of FRY1 is involved in long-distance as well as local regulatory activities in roots. The local up-regulation of PHT1 genes transcription in roots likely results from local depletion of Pi and is independent of the XRNs.This work was supported by an ANR-GENOPLANT grant (RIBOROOT-ANR06 GPLA 011) and the CEA agency.

P., & MacManus-Driscoll, J. L. (2013). Accurate determination of interface trap state parameters by admittance spectroscopy in the presence of a Schottky barrier contact: Application to ZnO-based solar cells. Journal of Applied Physics, 113(14), 144502 and may be found at https://doi.org/10.1063/1.4799633This work shows that when a Schottky barrier is present in a photovoltaic device, such as in a device with an ITO/ZnO contact, equivalent circuit analysis must be performed with admittance spectroscopy to accurately determine the pn junction interface recombination parameters (i.e., capture cross section and density of trap states). Without equivalent circuit analysis, a Schottky barrier can produce an error of similar to 4-orders of magnitude in the capture cross section and similar to 50% error in the measured density of trap states. Using a solution processed ZnO/Cu2O photovoltaic test system, we apply our analysis to clearly separate the contributions of interface states at the pn junction from the Schottky barrier at the ITO/ZnO contact so that the interface state recombination parameters can be accurately characterized. This work is widely applicable to the multitude of photovoltaic devices, which use ZnO adjacent to ITO.International Copper AssociationERC for the Advanced Investigator Grant, Novox [ERC-2009-adG 247276]Gates Cambridge TrustGirton College (Cambridge
