Each wall was analysed using an exclusionary set of criteria that evaluated and ranked a wall based on its suitability to VGS implementation. Sydney and Brisbane recorded the greatest proportional length of walls suitable for VGS, with 33.74% and 34.12% respectively. Conversely, Perth’s urban centre was the least feasible site in which to incorporate VGS, with over 97% of surveyed walls excluded, mainly due to the prevalence of less then 1 m high fence lines and glazed shopfronts. This study aimed to evaluate feasibility assessments of green wall retrofitability in highly urbanised areas with the intention of creating an analytical method that is accessible to all. This method, coupled with the promising number of feasible walls found in this study, emphasises the need for more government policy and incentives encouraging green wall uptake and could play a pivotal role in the expansion of green infrastructure and urban forestry.China is the second largest irrigated country in the world. Increasing irrigation intensity costs more water and energy, and produces more greenhouse gas (GHG). In the present study, the responses of maize economic and environmental benefits to different irrigation managements were analyzed in a 2-year field study. A purposely designed tube-study was conducted to explore mechanism underlying effects of irrigation managements in detail. Three treatments, rainfed (RF), flood irrigation (FI), and drip irrigation (DI) were included in the field. Five treatments, no irrigation, flood irrigation, irrigation in 0-30, 30-60, and 0-90 cm depth were conducted in the tube study. Compared to RF, grain yields of FI and DI significantly increased by 22.1 % and 35.7 %, respectively, the net ecosystem economic budget significantly increased by 34.2 % and 35.6 %, and carbon footprint decreased by 7.0 % and 12.7 % in the field study. The irrigation treatments in the tube study increased the global warming potential by 12.0-32.8 % and grain yield by 44.5-203.9 %, and reduced GHG intensity by 24.3-57.4 %, compared with no irrigation treatment. Water content at the top soil layer had the greatest impact on GHG emissions. In conclusion, the differences in grain yield and GHG emissions among irrigation managements are mainly due to the soil water content in space and time. Drip irrigation decreases GHG intensity by producing more grain yield due to the optimized soil water distribution in the root zone. Irrigation management with appropriate amount and frequency can increase economic benefit and reduce environmental cost in maize production.Because many heavy metals, such as zinc, are used in plating plants, it is important for wastewater treatment technologies to comply with wastewater regulations. In zinc wastewater treatment, zinc is separated from wastewater via hydroxide precipitation. However, ammonia tends to enter the wastewater produced from the plating process and inhibits hydroxide precipitation, which causes difficulties in treating wastewater. In this study, we investigated the effect of ammonia stripping on plating wastewater to remove ammonia, which inhibits wastewater treatment. Based on the results of this study, it was observed that the effectiveness of ammonia removal depends on the pH and air flow rate. It was also found that the presence of zinc increased the ammonia removal effect in most cases. This increase was due to the transformation of some of the precipitated zinc hydroxide in the wastewater into zinc oxide, which afforded an ammonia adsorption effect. After the addition of ethylenediamine-N,N,N’,N’-tetraacetic acid disodium salt dihydrate (EDTA・2Na), which is a complexing agent, the ammonia removal effect was slightly decreased. This result is attributed to the decrease in the amount of zinc oxide, which occurs due to the complex formation of EDTA with zinc precipitates in the wastewater. Furthermore, the addition of an excess amount of EDTA・2Na increased the concentration of free ammonia in the wastewater and increased the removal effect. Moreover, the effect of ammonia stripping was successfully applied to wastewater obtained from a zinc plating plant, and zinc wastewater treatment was improved with the removal of ammonia. These results indicate that ammonia stripping is effective in zinc wastewater treatment.The adoption of two-phase olive oil extraction processes has led to a significant increase in the amounts of two-phase olive pomace produced each year. This material is typically led to kernel oil extraction facilities that are forced to store the excessive amounts until treatment. During storage, malodorous compounds, like 4-ethylphenol, are formed that are then released to the atmosphere during drying, causing serious problems in a radius of several kilometers. At the same time, increased microbial activity in the stored pomace deteriorates kernel oil, diminishing its value. This deterioration is expressed as increased kernel oil acidity. In this work, the evolution of 4-ethylphenol concentration and kernel oil acidity as a function of storage duration and waste acidification were examined. The concentration of 4-ethylphenol in the unmodified two-phase olive pomace seems to be maximized after 23 d of storage, while kernel oil acidity reached a plateau of 10% after 70 d. Acidification at pH 2 prevented the production of 4-ethylphenol and kept kernel oil acidity at 5% for more than 100 d of storage. The results presented herein are a step towards understanding the processes taking place during two-phase olive pomace storage and exploring ways of minimizing their effects.

Siblings of people with Crohn’s disease (CD) share aspects of the disease phenotype (raised faecal calprotectin, altered microbiota), which are markers of risk for their own development of CD. The aim was to determine whether supplementation with prebiotic oligofructose/inulin induces a prebiotic response and impacts the risk phenotype in CD patients and siblings.

Patients with inactive CD (n=19, CD activity index <150) and 12 of their unaffected siblings (with calprotectin >50μg/g) ingested oligofructose/inulin (15g/day) for three weeks. Faecal microbiota (qPCR), intestinal permeability (lactulose-rhamnose test), blood T cells (flow-cytometry) and calprotectin (ELISA) were measured at baseline and follow-up.

Following oligofructose/inulin, calprotectin did not significantly change in patients (baseline mean 537 SD 535μg/g; follow-up mean 974 SD 1318μg/g, p=0.08) or siblings (baseline mean 73 SD 90μg/g follow up mean 58 SD 72μg/g, p=0.62). Faecal Bifidobacteria and Bifidobacterium longum increasedwith patients with inactive CD and was associated with alterations in other CD risk markers. Future research should focus on dietary intervention, including with prebiotics, in the primary prevention of CD.

In critically ill patients, nasogastric (NG) and nasojejunal (NJ) feeding tube placements are standard procedures. However, about 1.9% of blind tube insertions are malpositioned in the tracheopulmonary system, whereas guided procedures may result in a significant delay in nutritional delivery. Guided methods, such as Cortrak and fluoroscopy, have success rates of 82.6-85% and 93% respectively. The current study aims to investigate the performance of video-assisted feeding tube placement in the post-pyloric position using Integrated Real Time Imaging System (IRIS-) technology.

A prospective cohort study in patients requiring enteral feeding was conducted in a mixed medical-surgical intensive care unit (ICU). The primary outcome was the post-pyloric placement of IRIS feeding tubes, as confirmed by X-ray. Lirametostat nmr Secondary study objectives included gastric placement, ease of use and adverse events.

Thirty-one feeding tubes were placed using IRIS-technology; one patient was excluded for analysis due to protocol vioill ICU patients was only successful in 58% of cases and therefore currently cannot be recommended for this indication. However, a high success rate (96.8%) for gastric placement was achieved. IRIS tube placement detected tracheal misplacement immediately and had few adverse events.

Plasma odd-chain saturated fatty acids (OCFA) are inversely associated with type 2 diabetes (T2D) risk and may serve as biomarkers for dairy fat intake. Their distribution across different lipid classes and consequences for diabetes risk remain unknown.

To investigate the prospective associations of OCFA-containing lipid species with T2D risk and their dietary determinants.

Within the European Prospective Investigation into Cancer and Nutrition-Potsdam study (n=27,548), we applied a nested case-cohort design (subcohort n=1,248; T2D cases n=820; median follow-up 6.5 years). OCFA-containing lipids included triacylglycerols, free fatty acids (FFA), cholesteryl esters (CE), phosphatidylcholines, phosphatidylethanolamines, lysophosphatidylcholines, lysophosphatidylethanolamines, monoacylglycerols, and diacylglycerols. We estimated lipid class-specific associations between OCFA-containing lipids and T2D in sex-stratified Cox proportional-hazards models. We investigated correlations between lipids and dietary ely associated with T2D risk in women. Consumption of fat-rich dairy and fiber-rich foods were positively and red meat inversely correlated to OCFA-containing lipid plasma levels.

OCFA-containing lipids are linked to T2D risk in a lipid class and sex-specific manner, and they are correlated with several foods.

Body composition profiles influence the prognosis of several types of cancer; however, the role of body composition in patients with locally advanced gastric cancer (LAGC) after neoadjuvant treatment (NT) has not been well characterized.

A total of 213 patients with LAGC who underwent gastrectomy after NT at a high-volume institution from southern China were comprehensively evaluated for primary analysis. Additionally, 170 and 77 patients from Western China and Italy, respectively, were reviewed for external validation. The skeletal muscle index (SMI), skeletal muscle radiodensity (SMD), and the subcutaneous as well as the visceral adiposity index were assessed from clinically acquired CT scans at diagnosis and preoperatively.

Overall, none of the body composition parameters significantly changed after NT. The pre-NT skeletal muscle radiodensity (SMD) and change in SMI (ΔSMI) were both significantly lower in the patients with poor response (tumor regression <50%; mean SMD 43.5 vs 46.5, P=0.003; mean the pathological response after NT. An SMI loss >1.2 is closely associated with poorer outcomes and may indicate the need more supportive treatment.

Short dietary assessment tools can be useful to estimate food intake and diet quality in large-scale epidemiological studies with time constraints.

To determine the concurrent validity of the 17-item energy-restricted Mediterranean Adherence Screener (er-MEDAS) used in the PREDIMED (PREvención con DIeta MEDiterránea)-Plus trial and to analyse its capacity to detect 1-year changes in diet and cardiometabolic risk factors.

Validation study nested in the PREDIMED-Plus (n=6760, 55-75 years). Dietary data were collected by the 17-item er-MEDAS and a 143-item validated semiquantitative food frequency questionnaire (FFQ) at baseline and after 1-year intervention. Cardiometabolic risk markers were measured at both time points. A Mediterranean diet (MedDiet) score was derived from both instruments. Concurrent validity was evaluated by Pearson and intra-class correlation coefficients (ICC) and Bland and Altman limits of agreement. Construct validity was evaluated by assessing 1-year changes in FFQ-reported dietary intake and cardiometabolic profile changes in relation to changes in er-MEDAS.
