The vascular pulmonary pressure-flow (P-Q degree) relationships were studied in anesthetized dogs in order to characterize the distribution of total resistance in the pulmonary bed with respect to incremental resistance and critical closure prior to and after endotoxin insult. Incremental resistance was computed as the slope of the P-Q degree relation, whereas critical closure was referred to as the extrapolated pressure intercept at zero flow. P-Q degree coordinates were obtained by varying Q degree through graded inflation of right atrial balloon. The gradients across the arterial segment (Pa = Ppa - Pc) and across the venous segment (Pv = Pc - Pw) of the pulmonary vasculature were defined by the computation of effective capillary pressure (Pc) obtained from the analysis of the transient decay of pulmonary artery pressure (Ppa) toward wedge pressure (Pw) after arterial occlusion. Six group E dogs were infused with endotoxin at a rate of 0.25 microgram/kg min, while six additional animals served as control (group C). Endotoxin induced increases in flow resistance from 0.056 to 0.096 mm Hg/ml/min/kg due to arterial vasoconstriction and increases in critical closure from 2.3 to 8.4 mm Hg due to a venous waterfall. Before and after endotoxin insult, we assessed effects of each of three levels of static lung inflation (PEEP) on P-Q degree relationships.(ABSTRACT TRUNCATED AT 250 WORDS) [less ▲]

The impact of pre transplant (HCT) cytarabine consolidation therapy on post HCT outcomes has yet to be evaluated after reduced intensity or non-myeloablative conditioning. We analyzed 604 adults with acute myeloid leukemia (AML) in first complete remission (CR1) reported to the CIBMTR who received a RIC or NMA HCT from an HLA-identical sibling, HLA-matched unrelated donor (URD), or umbilical cord blood (UCB) donor in 2000-2010. We compared transplant outcomes based on exposure to cytarabine post remission consolidation. Three year survival rates were 36% (29-43%, 95% CI) in the no consolidation arm and 42% (37-47%, 95% CI) in the cytarabine consolidation arm (p=0.16). Disease free survival was 34% (27-41%, 95% CI) and 41% (35-46%, 95% CI) (p=0.15), respectively. Three year cumulative incidences of relapse were 37% (30-44%, 95% CI) and 38% (33-43%, 95% CI), respectively (p=0.80). Multivariate regression confirmed no effect of consolidation on relapse, DFS and survival. Prior to RIC/NMA HCT, these data suggest pre-HCT consolidation cytarabine does not significantly alter outcomes and support prompt transition to transplant as soon as morphologic CR1 is attained. If HCT is delayed while identifying a donor, our data suggest that consolidation does not increase transplant TRM and is reasonable if required. [less ▲]

OBJECTIVE: To evaluate equine cardiopulmonary function and recovery quality after administration of 0.25 or 0.50 mg/kg xylazine intravenously (IV) during recovery. STUDY DESIGN: Randomized, blinded, prospective, clinical study. ANIMALS: Horses (n = 20). METHODS: During recovery after 3 hours of isoflurane anesthesia for arthroscopic surgery, horses were administered either 0.25 mg/kg (G25, n = 10) or 0.50 mg/kg (G50, n = 10) xylazine intravenously. Vital signs and arterial blood samples were obtained during recovery before sedation (baseline), 5, 10, 20, 30, and 45 minutes after xylazine and 30 minutes after standing. The quality of recovery scores ranged from 10 to 72 (10 = best, 72 = worst). RESULTS: G25 horses recovered faster (mean +/- SD, 33 +/- 5 min) than G50 horses (50 +/- 7 min, P < .0001). Mean maximal decrease in arterial oxygen tension was 55 +/- 11 mmHg in G25 (at 10 minutes; P < .05) and 54 +/- 7 mmHg in G50 (at 20 minutes; P < .01). G25 group had a total recovery score (23 [range 18-29]) and number of attempts to stand (4 +/- 2) greater than the G50 group (18 [10-23] and 1 +/- 1, respectively; P < .001). CONCLUSIONS: Both doses of xylazine promoted a moderate and transient hypoxemia during recovery; however, the 0.5 mg/kg dose produced a longer and improved quality of recovery from anesthesia.

The effect of four KATP channel openers (KCOs) on the firing rate of CA1 pyramidal cells and A10 dopaminergic neurons was investigated using extracellular recording techniques in rat brain slices. Pinacidil, lemakalim, diazoxide and a new compound, BPDZ44, had an inhibitory effect on the electrical activity of CA1 pyramidal cells. They all had a similar potency. Only BPDZ44 and diazoxide inhibited the firing rate of A10 dopamine neurons. The sulfonylurea glipizide (1 microM) antagonized the effect of BPDZ44 and diazoxide on A10 neurons but failed to antagonize the effect of KCOs on CA1 pyramidal cells. These results show that differences exist among KCOs in their ability to decrease the electrical activity of various populations of central neurons. [less ▲]

The mRNA encoding prepro-Melanin concentrating hormone (ppMCH) is mainly expressed in the central nervous system but has also been detected at lower amount in many peripheral tissues including spleen and thymus. At the peptide level however, several forms of the precursor can be detected in these tissues and are sometimes expressed at similar levels compared to brain. In the present work, we have studied the in vitro action of a wide range of concentration (1 nM to 1 microM) of the different peptides encoded by ppMCH i.e. neuropeptide glycine-glutamic acid (NGE), neuropeptide glutamic acid-isoleucine (NEI), Melanin concentrating hormone (MCH) and the dipeptide NEI-MCH on peripheral blood mononuclear cells (PBMC) proliferation and cytokine production following anti-CD3 stimulation. Among them only MCH decreased PBMC proliferation with a maximal effect of 35% at 100 nM. Moreover as demonstrated by using ELISA, MCH significantly decreases IL-2 production by 25% but not IL-4, INF-gamma or TNF-alpha expression. Interestingly, exogenous IL-2 decreases significantly MCH-mediated inhibition, suggesting that it is an important downstream mediator of MCH action. Finally, we showed that after 7 to 9 days of incubation, MCH also inhibits proliferation of non-stimulated PBMC. Altogether, these data demonstrate that fully mature MCH modulates proliferation of anti-CD3 stimulated PBMC partially through regulation of IL-2 production. [less ▲]

Aims: To analyse the effects of plipastatin operon disruption and constitutive expression of surfactin operon in Bacillus subtilis 168 on surfactin productivity, in vitro invasive growth and antagonism against fungi. Methods and Results: The srfA native promoter was replaced by the constitutive promoter PrepU in B. subtilis 168 after integration of a functional sfp gene. Moreover, the plipastatin synthesis was further disrupted in the B. subtilis 168 derivatives. In liquid media, an earlier and higher expression of PrepU, than that found with PsrfA, led to a specific surfactin production fivefold higher after 6 h of culture. On solid media, not only the invasive growth and the haemolytic activity but also the antifungal activity of the constitutive strains were improved when compared to the parental strain BBG111. As expected, the disruption of the plipastatin operon strongly reduced in vitro antifungal properties but, interestingly, enhanced specific surfactin production (1Æ47 g g)1 of biomass), spreading behaviour and haemolytic activity of the strains. Conclusions: This work demonstrates for the first time the interdependency of surfactin and plipastatin regarding their biosynthesis as well as their influence on the biological activities of the producing strain. Significance and Impact of the Study: The constitutive overproduction of surfactin enhances the invasive growth and the in vitro antagonistic activity of the mutant strain. Both properties are known to play an important role in the biocontrol of plant diseases. Plipastatin operon disruption increases the surfactin productivity of mutant strains. These mutants are interesting for use in continuous bioprocesses for surfactin production or in bioremediation. [less ▲]

Many socially relevant odors are detected in rodent species by the vomeronasal organ and subsequently processed by the accessory olfactory system (AOS). We previously found that gonadectomized male and female rats treated in adulthood with testosterone propionate (TP) showed equivalent Fos responses in the AOS to odors derived from estrous females. Likewise, in contrast with numerous other mammalian species, gonadectomized female rats show surprisingly high levels of male-typical mounting behavior in response to adult TP. We tested the hypothesis that prenatal testosterone (T) exposure, acting via androgen receptors (ARs) or via estrogen receptors, masculinizes the AOS in rats of both sexes. Pregnant dams were treated with either the AR blocker, Flutamide, the aromatase inhibitor, 1,4,6-androstatriene-3,17-dione (ATD), or nothing (control) to assess the role of prenatal androgen and estradiol receptor activation, respectively, in this masculinization. Beginning at birth, male and female offspring were injected subcutaneously (sc) every other day with either ATD (pre- and neonatal ATD group) or oil vehicle (Flutamide and control groups) until postnatal Day 12. Subjects were gonadectomized as adults, hormonally treated and tested for different behaviors before having their AOS Fos responses to estrous female odors assessed. Prenatal treatment with Flutamide (but not ATD) significantly decreased anogenital distance and severely impaired intromissive and ejaculatory behaviors in males tested after TP replacement without disrupting mounting capacity in either sex. Pre- and neonatal treatment with ATD (but not Flutamide) enhanced lordosis responsiveness in males tested after sc injections of estradiol and progesterone, whereas these perinatal treatments had no effect on any aspect of masculine coital performance in either sex. After TP treatment, male and female control subjects preferred to approach a tethered stimulus female as opposed to a male, and prenatal Flutamide or perinatal ATD treatments did not modify this pattern of partner preference. Neuronal Fos responses to estrous odors were (as in previous studies) identical in the AOS of gonadectomized TP-treated control males and females. Prenatal Flutamide or perinatal ATD treatments failed to disrupt consistently this profile of Fos responses to estrous odors in the AOS of rats of either sex. These behavioral and neuroanatomical findings raise the possibility that the similar level of male-typical responsiveness to social odors that occurs in male and female rats after adult TP treatment results from nonsteroid-hormone-dependent, species-specific factors that act perinatally in the brains of rats of both sexes.

OBJECTIVE: To determine if pressure support ventilation (PSV) weaning from general anesthesia affects ventilation or oxygenation in horses. STUDY DESIGN: Prospective randomized clinical study. ANIMALS: Twenty client-owned healthy horses aged 5 +/- 2 years, weighing 456 +/- 90 kg. METHODS: In the control group (CG; n = 10) weaning was performed by a gradual decrease in respiratory rate (fR ) and in the PSV group (PSVG; n = 10) by a gradual decrease in fR with PSV. The effect of weaning was considered suboptimal if PaCO2 > 50 mmHg, arterial pH < 7.35 plus PaCO2 > 50 mmHg or PaO2 < 60 mmHg were observed at any time after disconnection from the ventilator until 30 minutes after the horse stood. Threshold values for each index were established and the predictive power of these values was tested. RESULTS: Pressure support ventilation group (PSVG) had (mean +/- SD) pH 7.36 +/- 0.02 and PaCO2 41 +/- 3 mmHg at weaning and the average lowest PaO2 69 +/- 6 mmHg was observed 15 minutes post weaning. The CG had pH 7.32 +/- 0.02 and PaCO2 57 +/- 6 mmHg at weaning and the average lowest PaO2 48 +/- 5 mmHg at 15 minutes post weaning. No accuracy in predicting weaning effect was observed for fR (p = 0.3474), minute volume (p = 0.1153), SaO2 (p = 0.1737) and PaO2 /PAO2 (p = 0.1529). A high accuracy in predicting an optimal effect of weaning was observed for VT > 10 L (p = 0.0001), fR /VT ratio </= 0.60 breaths minute(-1) L(-1) (p = 0.0001), VT /bodyweight > 18.5 mL kg(-1) (p = 0.0001) and PaO2 /FiO2 > 298 (p = 0.0002) at weaning. A high accuracy in predicting a suboptimal effect of weaning was observed for VT < 10 L (p = 0.0001), fR /VT ratio >/= 0.60 breaths minute(-1) L(-1) (p = 0.0001) and Pe'CO2 >/= 38 mmHg (p = 0.0001) at weaning. CONCLUSIONS AND CLINICAL RELEVANCE: Pressure support ventilation (PSV) weaning had a better respiratory outcome. A higher VT , VT /body weight, PaO2 /FiO2 ratio and a lower fR /VT ratio and Pe'CO2 were accurate in predicting the effect of weaning in healthy horses recovering from general anesthesia. [less ▲]

We have performed systematic studies of the lattice dynamics in LFeAsO (L = La, Ce, Pr, Nd, Sm) in the parent and in the similar to 10% F-doped compounds as a function of pressure and temperature. We have found that the modifications in the partial Fe density of phonon states are mainly governed by the Fe-As bond length. The change of this bond length explains the change of the Fe density of phonon states above 25 meV. We further observe anomalies in the behavior of the phonon mode near 16 meV. In the parent phase, this mode softens anomalously upon cooling through the structural phase transition. Upon F doping, this mode hardens indicating a strong electron-phonon coupling. This suggests that the corresponding phonons play an important role in the competition between superconductivity and magnetism in these materials. DOI: 10.1103/PhysRevB.87.064302 [less ▲]
