Objective: A trial was conducted to investigate the effects of supplemental levels of Mn provided by organic and inorganic trace mineral supplements on growth, tissue mineralization, mineral balance, and antioxidant status of growing broiler chicks. Methods: A total of 500 male chicks (8-d-old) were used in 10-day feeding trial, with 10 treatments and 10 replicates of 5 chicks per treatment. A 2×5 factorial design was used where supplemental Mn levels (0, 25, 50, 75, and 100 mg Mn/kg diet) were provided as MnSO<sub>4</sub>·H<sub>2</sub>O or MnPro. When Mn was supplied as MnPro, supplements of zinc, copper, iron, and selenium were supplied as organic minerals, whereas in MnSO<sub>4</sub>·H<sub>2</sub>O supplemented diets, inorganic salts were used as sources of other trace minerals. Performance data were fitted to a linearbroken line regression model to estimate the optimal supplemental Mn levels. Results: Manganese supplementation improved body weight, average daily gain (ADG) and feed conversion ratio (FCR) compared with chicks fed diets not supplemented with Mn. Manganese in liver, breast muscle, and tibia were greatest at 50, 75, and 100 mg supplemental Mn/kg diet, respectively. Higher activities of glutathione peroxidase and superoxide dismutase (total-SOD) were found in both liver and breast muscle of chicks fed diets supplemented with inorganic minerals. In chicks fed MnSO<sub>4</sub>·H<sub>2</sub>O, ADG, FCR, Mn balance, and concentration in liver were optimized at 59.8, 74.3, 20.6, and 43.1 mg supplemental Mn/kg diet, respectively. In MnPro fed chicks, ADG, FCR, Mn balance, and concentration in liver and breast were optimized at 20.6, 38.0, 16.6, 33.5, and 62.3 mg supplemental Mn/kg, respectively. Conclusion: Lower levels of organic Mn were required by growing chicks for performance optimization compared to inorganic Mn. Based on the FCR, the ideal supplemental levels of organic and inorganic Mn in chick feeds were 38.0 and 74.3 mg Mn/kg diet, respectively.

Background/Aims: Self-expandable metallic stents (SEMSs) are widely adopted for the palliation of dysphagia in patients with malig-nant esophageal strictures. An important adverse event is the development of SEMS-induced esophagorespiratory fistulas (SEMS-ERFs). This study aimed to assess the risk factors related to the development of SEMS-ERF after SEMS placement in patients withesophageal cancer. Methods: This retrospective study was performed at the Instituto do Cancer do Estado de São Paulo. All patients with malignantesophageal strictures who underwent esophageal SEMS placement between 2009 and 2019 were included in the study. Results: Of the 335 patients, 37 (11.0%) developed SEMS-ERF, with a median time of 129 days after SEMS placement. Stent flare of 28mm (hazard ratio [HR], 2.05; 95% confidence interval [CI], 1.15–5.51; p=0.02) and post-stent chemotherapy (HR, 2.0; 95% CI, 1.01–4.00; p=0.05) were associated with an increased risk of developing SEMS-ERF, while lower-third tumors were a protective factor (HR,0.5; 95% CI, 0.26–0.85; p=0.01). No difference was observed in overall survival. Conclusions: The incidence of SEMS-ERFs was 11%, with a median time of 129 days after SEMS placement. Post-stent chemotherapyand a 28 mm stent flare were associated with a higher risk of SEMS-ERF.

An experimental and numerical assessment of multilayer active magnetic regenerators (AMR) composed of gadolinium (Gd) and gadolinium–yttrium (Gd–Y) alloys (Gd 97.34 Y 2.66, Gd 95.98Y 4.02 and Gd 94.79Y 5.21) is presented. First, by calculating the adiabatic temperature change and the isothermal entropy change from the experimental data for the above materials, we show that, with reasonable accuracy for engineering design purposes, these properties can be determined by shifting the properties of pure Gd to the Curie temperature of the Gd–Y alloy — a common but not yet validated assumption in the design of Gd–Y AMRs with a low Y content. Next, we show that the optimal Gd–Y layer fraction in multilayer AMRs can be determined using the figure of merit known as the material refrigerant capacity (RC), which agrees well with the results from a more complex one-dimensional thermal non-equilibrium porous medium AMR model. Finally, the performance of the latter model is verified against the experimental cooling power data for two- and three-layer Gd–Y regenerators at temperature spans of 25, 30 and 35 K.

The use of benefi cial fungi and bacteria can improve growth, yield and food quality of plants. The electrical conductivity (EC) of a nutrient solution is closely linked to better nutrition of arugula plants in a hydroponic system. Therefore, objectives of current study were to evaluate isolated and combined eff ect of inoculation with Azospirillum brasilense and Trichoderma hazianum under two ECs on root-shoot biomass, nutrition and yield of arugula in hydroponic cultivation system. The experi- ment was designed in a strip-plot block with fi ve replications in a 4 × 2 factorial scheme. The treatments were consisted of four microbial inoculations (without, A. brasilense, T. harzianum and co-inoculation of both) and two ECs (1.4 and 1.6 dS m −1). The higher EC with A. brasilense inoculation provided greater growth of arugula plants in a hydroponic system. Inoculation with A. brasilense has increased leaf area, shoot–root length, leaf chlorophyll index (LCI) and shoot ammonium accumulation while reduced root-shoot nitrate accumulation. The leaf nutrition or biofortifi cation of arugula plants with K, S, Ca, Mg, Zn, Fe, and Mn was improved under both isolated and combined inoculations of A. brasilense and T. harzianum .

The rhizobacteria of genus Azospirillum and Bacillus are efective at fxing atmospheric nitrogen, promote plant growth and can largely contribute to benefcial recovery from degraded pastures. This study aimed to evaluate the development and nutritional status of Urochloa brizantha cv. Marandu in response to nitrogen doses along with inoculation of Azospirillum brasilense and Bacillus subtilis. The experiment was carried in a completely randomized design in a greenhouse with four replications and in factorial scheme 4×5. The treatments were consisted of seeds inoculation (without inoculation, A. brasilense (strains Ab-V5, Ab-V6), B. subtilis (strain CCTB04) and co-inoculation with strains of A. brasilense+strain of B. subtilis, and nitrogen doses (0, 50, 100, 150 and 200 kg ha−1, equivalent to 0, 25, 50, 75 and 100 mg dm−3 N) from urea. The sole inoculation of A. brasilense and B. subitilis promoted plant height of Marandu grass along with nitrogen fertilization. The co-inoculation of these bacteria increased potassium accumulation in Marandu grass along with nitrogen doses. Regardless of bacterial inoculation, number of tillers, leaves, dry matter accumulation, crude protein and accumulations of N, P, Ca, S and Mg were increased with increasing nitrogen doses in the frst forage cycle.
