Background: Reversal of neuromuscular blockade (NMB) at the end of surgery is important for reducing postoperative residual NMB; this is associated with an increased risk of postoperative pulmonary complications (PPCs). Moreover, PPCs are associated with poor prognosis after video-assisted thoracoscopic surgery (VATS) for lobectomy. We compared the effects of two reversal agents, sugammadex and neostigmine, on the incidence of PPCs and duration of hospital stay in patients undergoing VATS lobectomy.Methods: After VATS lobectomy was completed under neuromuscular monitoring, the sugammadex group (n = 46) received sugammadex 2 mg/kg, while the neostigmine group (n = 47) received neostigmine 0.05 mg/kg with atropine 0.02 mg/kg after at least the third twitch in response to the train of four stimulation. The primary outcome was incidence of PPCs. The secondary outcomes were duration of hospital stay and intensive care unit (ICU) admission. Results: There was no significant difference in the incidence of PPCs for both the sugammadex and neostigmine groups (32.6% and 40.4%, respectively; risk difference = 0.08; 95% confidence interval = [−0.12, 0.27]; P = 0.434). The lengths of hospital (P = 0.431) and ICU (P = 0.964) stays were not significantly different between the two groups.Conclusions: The clinical use of sugammadex and neostigmine in NMB reversal for patients undergoing VATS lobectomy was not significantly different in the incidence of PPCs and duration of hospital and ICU stay.
Unbalanced dietary habits and gut dysmotility are causative factors in metabolic and functional gut disorders, including obesity, diabetes, and constipation. Reduction in luminal butyrate synthesis is known to be associated with gut dysbioses, and studies have suggested that restoring butyrate formation in the colon may improve gut health. In contrast, shifts in different types of gut microbiota may inhibit luminal butyrate synthesis, requiring different treatments to restore colonic bacterial butyrate synthesis. We investigated the influence of high-fat diets (HFD) and low-fiber diets (LFD), and loperamide (LPM) administration, on key bacteria and genes involved in reduction of butyrate synthesis in mice. MiSeq-based microbiota analysis and HiSeq-based differential gene analysis indicated that different types of bacteria and genes were involved in butyrate metabolism in each treatment. Dietary modulation depleted butyrate kinase and phosphate butyryl transferase by decreasing members of the Bacteroidales and Parabacteroides. The HFD also depleted genes involved in succinate synthesis by decreasing Lactobacillus. The LFD and LPM treatments depleted genes involved in crotonoyl-CoA synthesis by decreasing Roseburia and Oscilllibacter. Taken together, our results suggest that different types of bacteria and genes were involved in gut dysbiosis, and that selected treatments may be needed depending on the cause of gut dysfunction.
In this paper, we develop a model to describe the generalized wave-particle instability in a quasi-neutral plasma. We analyze the quasi-linear diffusion equation for particles by expressing an arbitrary unstable and resonant wave mode as a Gaussian wave packet, allowing for an arbitrary direction of propagation with respect to the background magnetic field. We show that the localized energy density of the Gaussian wave packet determines the velocityspace range in which the dominant wave-particle instability and counteracting damping contributions are effective. Moreover, we derive a relation describing the diffusive trajectories of resonant particles in velocity space under the action of such an interplay between the wave-particle instability and damping. For the numerical computation of our theoretical model, we develop a mathematical approach based on the Crank-Nicolson scheme to solve the full quasi-linear diffusion equation. Our numerical analysis solves the time evolution of the velocity distribution function under the action of a dominant wave-particle instability and counteracting damping and shows a good agreement with our theoretical description. As an application, we use our model to study the oblique fastmagnetosonic/whistler instability, which is proposed as a scattering mechanism for strahl electrons in the solar wind. In addition, we numerically solve the full Fokker-Planck equation to compute the time evolution of the electron-strahl distribution function under the action of Coulomb collisions with core electrons and protons after the collisionless action of the oblique fast-magnetosonic/whistler instability.
Shin (2015) Invitro and invivo antimicrobial efficacy of natural plant-derived compounds against Vibriocholerae of O1 El Tor Inaba serotype, Bioscience, Biotechnology, and Biochemistry, 79:3, 475-483, DOI: 10.1080/09168451.2014 In this study, we investigated antibacterial activities of 20 plant-derived natural compounds against Gram-negative enteric pathogens. We found that both flavonoids and non-flavonoids, including honokiol and magnolol, possess specific antibacterial activities against V. cholerae, but not against other species of Gram-negative bacterium which we tested. Using various antibacterial assays, we determined that there was a dose-dependent bactericidal and biofilm inhibitory activity of honokiol and magnolol against Vibrio cholerae. In addition to antibacterial activities, these molecules also induced an attenuating effect on reactive oxygen species (ROS) production and pro-inflammatory responses generated by macrophages in response to lipopolysaccharides (LPS). Additionally, Caenorhabditis elegans lethality assay revealed that honokiol and magnolol have an ability to extend a lifespan of V. choleraeinfected worms, contributing to prolonged survival of worms after lethal infection. Altogether, our data show for the first time that honokiol and magnolol may be considered as attractive protective or preventive food adjuncts for cholera.
Objectives Body protective compound-157 (BPC-157) is a stable gastric pentadecapeptide that has been effective in trials aiming to increase wound healing capabilities and decrease inflammatory cell influx, including studies on the healing of muscles and tendons. There are no studies about the effect of BPC-157 on pain transmission via nociception. This study examined the antinociceptive effects of BPC-157 using formalin tests and immunohistochemistry. Methods Rats were randomly divided into the control, morphine and BPC-157 groups. Pain behavior was quantified periodically at 5- and 35- min intervals (representative values of phases 1 and 2) by counting the number of flinches exhibited by the injected paw after injection. The dorsal root ganglia (DRG) and spinal cords (SC) were collected, and then, the number of cytokine-positive cells was determined via immunostaining. Results BPC-157 dose-dependently decreased the number of flinches during phase 1 but did not decrease the number of flinches during phase 2. During phase 1, interleukin-1β (IL-1β) in the DRG tissue was significantly different in the morphine, 10 μg/kg BPC-157, and 20 μg/kg BPC-157 groups. During phase 2, statistical significance was achieved in the DRG tissue in the morphine, 20 μg/kg BPC-157, and 40 μg/kg BPC-157 groups. During phase 1, interleukin-6 was significantly different in the DRG tissue in the morphine group and the SC tissue in the 10 μg/kg BPC-157 group. During phase 2, statistical significance was achieved in the morphine group and the BPC-157 20 μg/kg group in both the DRG and SC tissues. There were no significant differences in tumor necrosis factor-α between the DRG and SC tissues. Conclusions BPC-157 was effective during phase 1 but not during phase 2, as determined by the formalin test. BPC-157 decreased the expression of IL-1β in the DRG tissue in phases 1 and 2.
