It was found that all models performed relatively well with a Nash-Sutcliffe Efficiency (NSE) of 0.42 - 0.61 for TP and 0.37 - 0.63 for TN. The most important design characteristics were filter media type and depth for TP treatment, and vegetation type and submerged zone depth for TN treatment. In addition, infiltration rate and inflow concentrations were the operational conditions that greatly influence outflow TP and TN concentrations from stormwater biofilters. As such, these variables need to be carefully considered when designing and operating stormwater biofilters. Sensitivity analysis results indicate that the model was quite sensitive to all regression coefficients and intercepts. Additional modelling exercises show that the model could be further simplified by reducing the number of cross-correlated parameters. These models can be used by practitioners for not just optimising the design, but also operating biofilters using real-time monitoring and control to achieve optimum performance.Complete biological denitrification is usually restricted in electron donor lacking waters. Hydrogenotrophic denitrification attracts attention for its clean and cost-efficiency advantages. Therein, the hydrogen could be effectively generated by microbial electrolysis cells (MECs) from organic wastes. In this study, a gas diffusion membrane (GDM) integrated MEC (MMEC) was constructed and provided a novel non-polluting approach for nitrate contaminated water remediation, in which the hydrogen was recovered from substrate degradation in anode and diffused across GDM as electron donor for denitrification. The high overall nitrogen removal of 91 ± 0.1%-95 ± 1.9% and 90 ± 1.6%-94 ± 2.2% were respectively achieved in Ti-MMEC and SS-MMEC with titanium and stainless-steel mesh as cathode at all applied voltages (0.4-0.8 V). Decreasing applied voltage from 0.8 to 0.4 V significantly improved the electron utilization efficiency for denitrification from 26 ± 3.6% to 73 ± 0.1% in Ti-MMEC. Integrating MEC with GDM greatly improved TN removal by 40% under applied voltage of 0.8 V. The hydrogenotrophic denitrifiers of Rhodocyclaceae, Paracoccus, and Dethiobacter, dominated in MMECs facilitating TN removal. Functional denitrification related genes including napAB, nirKS, norBC and nosZ predicted by PICRUSt2 based on 16S rRNA gene data demonstrated higher abundance in MMECs.

We study the significance of stories about bad trips among users of psychedelics. Drawing on narrative theory, we describe the characteristics of such stories and explore the work they do.

In-depth qualitative interviews with 50 Norwegian users of psychedelics.

Almost all participants had frightening experiences when using psychedelics and many described these as bad trips. The key feature of a bad trip was a feeling of losing oneself or going crazy, or ego dissolution. Most users said that these experiences could be avoided by following certain rules, based on tacit knowledge in the subcultures of users. Possessing such knowledge was part of symbolic boundary work that distinguished between drug culture insiders and outsiders. Some also rejected the validity of the term bad trip altogether, arguing that such experiences reflected the lack of such competence. Finally, and most importantly, most participants argued that unpleasant experiences during bad trips had been beneficial and had sometimes given teasant experiences with the drugs.In continuous flash suppression (CFS), an image presented to one eye is suppressed from awareness by a dynamic image masker presented to the other eye. Previous studies report that face stimuli break out of CFS more readily when they are oriented upright and contain ecologically relevant information such as facial expressions or direct eye gaze, potentially implicating face processing in the mechanisms of interocular competition. It is unknown, however, whether face content helps to drive interocular suppression when incorporated into the dynamic masker itself, either by engaging higher-level visual mechanisms that underlie face detection or due to lower-level image features that the faces happen to contain. To investigate this, we devised a dynamic mask composed of upright faces and tested how well it suppressed detection of face or grating targets presented to the other eye. Relative contributions of higher-level and lower-level features were compared by manipulating the image properties of the mask. Results show that the dynamic face mask is strikingly effective at suppressing sensory input presented to the opposing eye, but its effectiveness is largely attributable to image texture, which can be quantified in terms of image entropy and edge density. This is because strong suppression was still observed following phase-scrambling or spatial inversion of the face elements, and while a target-selective effect was observed for the face mask, inverting the face elements to interfere with configural processing did not significantly diminish this effect. Thus, visual properties of faces, such as their image entropy and complex phase structure, predominate in driving interocular suppression rather than face detection per se.An experiment was designed to evaluate the effectiveness of the recently developed 7 & 7 Synch protocol to synchronize estrus among recipients prior to embryo transfer (ET). Postpartum beef cows (n = 1358) across thirteen locations were assigned to either the 7-d CO-Synch + CIDR protocol or the 7 & 7 Synch protocol prior to ET. Cows were preassigned to balanced treatments within location based on age and days postpartum, with body condition score recorded at ET. Cows assigned to the 7-d CO-Synch + CIDR protocol were administered gonadotropin-releasing hormone (GnRH; 100 μg gonadorelin acetate) on Day 7, an intravaginal controlled internal drug release (CIDR; 1.38 g progesterone) from Day 7 to Day 14, and prostaglandin F2α (PGF2α; 25 mg dinoprost tromethamine) coincident with CIDR removal on Day 14. Cows assigned to the 7 & 7 Synch protocol were administered PGF2α (25 mg dinoprost tromethamine) coincident with CIDR insertion on Day 0, GnRH (100 μg gonadorelin acetate) on Day 7, and PGF2α (25 mg dinoprost tromensequently, the proportion pregnant to ET was greater (P less then 0.03) following the 7 & 7 Synch protocol (40% [263/653]) compared to the 7-d CO-Synch + CIDR protocol (34% [228/664]). In summary, the 7 & 7 Synch protocol involving administration of PGF2α and treatment with a CIDR for 7 days prior to GnRH improved the likelihood of estrus expression in recipients, increased the proportion of cows eligible to receive an embryo, which resulted in a greater pregnancy rate to ET.Heat stress is associated with increased production of reactive oxygen species (ROS) and disruption of bovine oocyte function. Here, we examined whether the antioxidant melatonin can alleviate the deleterious effects of heat stress on oocyte developmental competence. Cumulus-oocyte complexes were matured for 22 h at 38.5 °C (control) or for 22 h at 41.5 °C (heat shock) with or without 1.0 × 10-7 M melatonin. At the end of maturation, a subgroup of oocytes was examined for nuclear and cytoplasmic maturation, ROS level and mitochondrial membrane potential. A second subgroup of oocytes underwent fertilization (18 h), and putative zygotes were cultured in an incubator equipped with a time-lapse system for ∼190 h. Cleavage rate and the proportion of blastocysts, as well as embryo kinetics were recorded. Expanded blastocysts were collected and their transcript abundance was evaluated. Heat shock increased ROS and reduced the proportion of oocytes that resumed meiosis and reached the metaphase-II stage. Exposing oochocked oocytes to some extent and had a beneficial effect on maternal mitochondrial transcripts in the developed blastocysts.

Radical cystectomy (RC) remains the standard of care for muscle-invasive bladder cancer (MIBC). Because of the higher overall risks associated with RC, particularly in the elderly patients with multiple comorbidities, other less invasive bladder preservation strategies have been considered.

This is a retrospective chart review of patients diagnosed with MIBC, pT2-4N0-2M0, at the American University of Beirut Medical Center between 2007 and 2017.

98 patients, 85 (86.7%) males and 13 (13.3%) females, were included. Of the 98 patients, 19 (19.3%) patients were treated with upfront CRT, 35 (35.7%) were treated with upfront RC and 44 (45%) were treated with NAC. 26 (26.5%) patients underwent RC after NAC and 18 (18.4%) received CRT after NAC. The mean overall survival (OS) for the different treatment modalities was 69.4, 60.4, 56.1 and 44.2 months for RC, CRT, RC post-NAC and CRT post-NAC, respectively (p=0.83). The median disease-free survival (DFS) was 29, 22, 21 and 16 months for RC, CRT, RC post-NAC and CRT post-NAC, respectively (p=0.49). Patients with pT3/T4 had a higher risk of death by 3.335 folds compared to pT2 (95% CI [1.321-8.422], p<0.05).

No difference was noted in the OS and DFS between the groups who underwent RC post-NAC and CRT post-NAC. These findings further support the possibility of bladder preservation after the treatment with NAC for MIBC. The pathologic T stage at diagnosis is an important prognostic factor regardless of treatment modality.

The process, from its inception to enactment, took a total of two years and eight months. Using an historical analysis approach, the authors describe the policy advocates' activities aimed at gaining acceptance for the alcohol control policy, and provide advice for policy advocates attempting to pass similar laws in other countries. The advocacy process went through three distinct stages an agenda-setting stage, followed by a policy-formulation stage and a legitimization stage. The agenda-setting stage involved educating the public about the harmful use of alcohol and its effect on society; during the second stage, an appropriate policy response was drafted and, lastly, during the legitimization phase, policy advocates navigated the political landscape in order to win final approval for the proposed policy. A tri-party coalition strategy (known as the 'triangle that moves the mountain' strategy) was employed which synchronized the work of three forces, each representing one of the three points of a triangle-of policy, knowledge, and civic expertise-coupled with media advocacy activities in order to increase the public and government acceptance of the proposed law. The public's view of the proposed law was critical to influence politicians to favour its adoption. While the knowledge and civic forces play a larger role during the agenda-setting and policy-formulation stages, the policy force was more active during the legitimization stage. Lastly, having a funding agency in place, such as Thai Health in this example, to provide a sustained source of funds for health promotion initiatives was critically important for policy advocates. BL-918 clinical trial Economic growth is an important determinant of increased consumption of alcohol per capita, and Thailand's experience of passing its first alcohol control law may serve as a useful guide for other low- or middle-income countries wishing to put a national alcohol control law in place.
