Is Palm Kernel Cake a Suitable Alternative Feed Ingredient for Poultry?

Simple Summary Supply of raw materials such as corn and soybean meal as livestock and poultry feeds may be limited and is a significant concern during the Covid-19 pandemic especially for the countries that depend on importation of raw materials. Consequently, the palm kernel cake has been proposed as an alternative raw material for animal feeds to reduce importation dependency. The chemical composition of palm kernel cake varies depending on the method of oil extraction. The crude fiber content of palm kernel cake is acceptable to most ruminants but is considered high for poultry. Biodegradation of palm kernel cake through solid-state fermentation can improve its nutritional quality, improving broiler health status and growth performance. Palm kernel cake (PKC), a by-product of oil extracted from palm nuts through expeller press or solvent extraction procedures is one of the highest quantities of locally available and potentially inexpensive agricultural product. PKC provides approximately 14-18% of crude protein (CP), 12-20% crude fiber (CF), 3-9% ether extract (EE), and different amounts of various minerals that feasible to be used as a partial substitute of soybean meal (SBM) and corn in poultry nutrition. Poultry’s digestibility is reported to be compromised due to the indigestion of the high fiber content, making PKC potentially low for poultry feeding. Nevertheless, solid-state fermentation (SSF) can be applied to improve the nutritional quality of PKC by improving the CP and reducing CF content. PKC also contains beta-mannan polysaccharide, which works as a prebiotic. However, there is a wide variation for the inclusion level of PKC in the broiler diet. These variations may be due to the quality of PKC, its sources, processing methods and value-added treatment. It has been documented that 10-15% of treated PKC could be included in the broiler’s diets. The inclusion levels will not contribute to a negative impact on the growth performances and carcass yield. Furthermore, it will not compromise intestinal microflora, morphology, nutrient digestibility, and immune system. PKC with a proper SSF process (FPKC) can be offered up to 10-15% in the diets without affecting broilers’ production performance.

Tannic acid and Poly(N-acryloyl morpholine) layer-by-layer built hemodialysis membrane surface for intervening oxidative stress integrated with high biocompatibility and dialysis performance

Oxidative stress is a compelling risk factor during hemodialysis in patients with renal failure to elevated mortality risk. Intervening the effect of oxidative stress in the pathogenesis of dialysis-associated complications requires developing a more direct hemodialysis membrane route to prevent and relieve oxidative stress in the dialysis process. In this work, combining the anti-oxidative property of tannic acid (TA) and high biocompatibility of poly (N-acryloyl morpholine) (PACMO), the TA-PACMO functionalized poly (ether sulfone) (PES) hemodialysis membranes have been fabricated using the hydrogen-bonded layer-by-layer (HB-LbL) assembly technology. The functionalized membranes directly quenched excess reactive oxygen species, improved the serum total antioxidant capacity, and suppressed lipid peroxidation and protein glycosylation. More interestingly, the TA-PACMO functionalized hemodialysis membranes effectively protected cardiomyocytes (H9C2), and vascular endothelial cells (HUVEC) from oxidative damage the improvement of antioxidant enzymes activities such as superoxide dismutase and catalase. The introduction of PACMO indicated in considerable improvement of blood compatibility and reduction of complement activation compared to a single TA modified hemodialysis membrane. The typical toxins, including urea and lysozyme, were efficiently removed from the dialysis simulant experiment, confirming the feasibility of the TA-PACMO HB-LbL functionalized strategy. The results revealed that, with the TA-PACMO content increasing, the functionalized membranes with superior comprehensive performances had stronger anti-oxidative stress, better biocompatibility, and more efficient dialysis performance. The present work provided a promising candidate in the development and application of hemodialysis membrane against oxidative stress, which alleviated patients’ complications to address the long-term hemodialysis.

Molecular identification of Entamoeba histolytica, E. dispar y E. moshkovskii in children with diarrhea from Maracaibo, Venezuela

Introduction: Entamoeba histolytica is the amebiasis-producing parasite, however; Entamoeba dispar, Entamoeba moshkovskii and Entamoeba bangladeshi are nonpathogenic amoebae, morphologically identical to this one, so molecular techniques are needed for their differentiation. Objective: To identify the frequency of Entamoeba species by Polymerase Chain Reaction (PCR), in fecal samples from children under 5 years of age with diarrhea, from Maracaibo, Venezuela. Materials and methods: A fecal sample was collected per individual from 75 children with diarrhea (case group) and 25 children without diarrhea (control group). Stools were evaluated by microscopic examination, formol-ether concentration method and nested-multiplex PCR in a single round, for the identification of E. histolytica, E. dispar and E. moshkovskii. In addition, a survey was conducted in which demographic data, signs, clinical manifestations, and socioeconomic status were defined. Results: 48% of the children (38 from the case group and 10 from the control group) had intestinal parasites. Only 4 children presented cysts of the Entamoeba complex in their samples, (3 from case group and 1 control group). By means of PCR 9 samples (9%) amplified for the studied amoebae. In the case group: 3 (28.13%) for E. histolytica, 4 (30.50%) for E. dispar and 1 (9.37%) for E. moshkovskii; while only 1 (25%) sample amplified for E. dispar in the control group. Conclusion: In general, E. dispar predominated; however, all those infected with E. histolytica were detected within the group of children with diarrhea and the first case of E. moshkovskii was detected in the region.

Numerical modelling of sorption-enhanced gasification: Development of a fuel decomposition model

Sorption-enhanced gasification (SEG) is a promising technology for producing renewable feedstock gas to be used in biofuel synthesis processes, especially in dimethyl ether (DME) synthesis. To adopt the technology on a commercial scale, it is necessary to acquire knowledge about the related operational characteristics. The SEG process is carried out at lower temperatures than those employed in conventional gasifiers. A typical operating range is from 600 degrees C to 800 degrees C. Fuel decomposition experiments have shown distribution of the decomposition products to vary by the process temperature in this operating range, and thus, it is important to adapt this phenomenon for modelling the SEG process. To model the temperature dependence of the decomposition products, a fuel model was developed. Fuel decomposition experiments were conducted to obtain the boundary conditions for the fuel model. The developed fuel model was implemented to an SEG model frame, and the model prediction was compared against data from a 200 kWth dual fluidised bed facility. The model gave satisfactory predictions for producer composition and temperature trends. Furthermore, the main balances of the model were in agreement with typical trends of the SEG process. The conducted simulations improved our understanding of material balances in SEG reactors. Knowledge from physical operations governing the process is of value in further development of the technology.

Mixed lithium fluoride-nitride ionic conducting interphase for dendrite-free lithium metal anode

The lithium (Li) metal battery reveals appealing merits in energy density but suffers from problems of dendrite growth and low coulombic efficiency before its applications. The ether electrolytes entitle Li metal batteries with more smooth Li stripping/deposition but narrow electrochemical stability in contrast to carbonate electrolyte. circumventing this contradictory, a lithium fluoride-nitride mixed ionic conducting interphase was embedded on lithium surface via formulated fluorine-rich carbonate and cyclophosphonitrile, which renders a dendrite-free plating/stripping over 2200 h and extend the electrochuemcial window of ether electrolyte to 4.5 V with the assistance of experiments and calculating simulations, ensuring LiCoO2 to operate efficiently over 200 cycles with nearly no capacity decay.

A novel porous polymeric microsphere for the selective adsorption and isolation of conalbumin

Porous polymeric microspheres, poly(styrene-divinyl benzene, PSDVB)-poly(ethylene glycol monoallyl ether, PEGMAE), termed as PSDVB-PEGMAE, are prepared via double emulsion interfacial polymerization strategy. PSDVB-PEGMAE microspheres exhibit a mean diameter of 2.98 um, and possess heterogeneous porous structure with a pore volume of 0.354 cm(3) g(-1) and a pore size of 34.3 nm. PEGMAE moiety is identified on the external surface of the microspheres, while both PSDVB and PEGMAE moieties are found in the interior pores. The PSDVB-PEGMAE microspheres possess favorable selectivity towards the adsorption of conalbumin (ConA) through hydrogen-bonding and hydrophobic interactions, via surface and inter-pore adsorption. At pH 6, an adsorption capacity of 171.9 mg g(-1) is achieved for ConA. The captured ConA may be readily recovered by stripping with a cetane trimethyl ammonium bromide (CTAB) solution (0.1%, m/v). The microspheres are further used for the isolation of ConA from egg white, deriving high purity ConA as demonstrated by SDS-PAGE assay. (C) 2020 Elsevier B.V. All rights reserved.

Risk of QTc Interval Prolongation Associated With Circulating Anti-Ro/SSA Antibodies Among US Veterans: An Observational Cohort Study

BACKGROUND: Anti-Sjogren’s syndrome-related antigen A-antibodies (anti-Ro/SSA-antibodies) are responsible for a novel form of acquired long-QT syndrome, owing to autoimmune-mediated inhibition of cardiac human ether-a-go-go-related gene-potassium channels. However, current evidence derives only from basic mechanistic studies and relatively small sample-size clinical investigations. Hence, the aim of our study is to estimate the risk of QTc prolongation associated with the presence of anti-Ro/SSA-antibodies in a large population of unselected subjects. METHODS AND RESULTS: This is a retrospective observational cohort study using the Veterans Affairs Informatics and Computing Infrastructure. Participants were veterans who were tested for anti-Ro/SSA status and had an ECG. Descriptive statistics and univariate and multivariate logistic regression analyses were performed to identify risk factors for heart rate-corrected QT interval (QTc) prolongation. The study population consisted of 7339 subjects (61.4 +/- 12.2 years), 612 of whom were anti-Ro/SSA-positive (8.3%). Subjects who were anti-Ro/SSA-positive showed an increased prevalence of QTc prolongation, in the presence of other concomitant risk factors (crude odds ratios [OR], 1.67 [1.26-2.21] for QTc >470/480 ms; 2.32 [1.54-3.49] for QTc >490 ms; 2.77 [1.66-4.60] for QTc >500 ms), independent of a connective tissue disease history. Adjustments for age, sex, electrolytes, cardiovascular risk factors/diseases, and medications gradually attenuated QTc prolongation estimates, particularly when QT-prolonging drugs were added to the model. Nevertheless, stepwise-fully adjusted OR for the higher cutoffs remained significantly increased in anti-Ro/SSA-positive subjects, particularly for QTc >500 ms (2.27 [1.34-3.87]). CONCLUSIONS: Anti-Ro/SSA-antibody positivity was independently associated with an increased risk of marked QTc prolongation in a large cohort of US veterans. Our data suggest that within the general population individuals who are anti-Ro/SSA-positive may represent a subgroup of patients particularly predisposed to ventricular arrhythmias/sudden cardiac death.

Ethylene/propylene separation using mixed matrix membranes of poly (ether block amide)/nano-zeolite (NaY or NaA)

Generally, the energy and capital intensive cryogenic distillation process is applied to separate light olefins. To lower the cost of light olefin production, mixed matrix membranes (MMMs) incorporating nano-zeolite (NaY or NaA) into a rubbery poly (ether block amide) (PEBA 2533) were fabricated to separate a propylene/ethylene mixture. The effect of additive content and kind, MMM thickness, and operating temperature and pressure on the separation performance of the synthesized membranes for a propylene/ethylene mixture were investigated. As an additive, NaY was found to be more effective than NaA. Interestingly, the result of pure gas adsorption was consistent with the permeation performance of the membranes. Membranes with 6 wt% NaY showed the highest C3H6/C2H4 selectivity in all synthesized membranes (3 wt%-10 wt%), on which, the C3H6/C2H4 selectivity was increased from 2.3 to 13.1, the permeability of propylene increased from 194 barrer to 262 barrer and the permeability of ethylene decreased from 85 barrer to 19.8 barrer when the propylene concentration in feed mixture increased from 10 mol% to 80 mol% at -35 degrees C and 0.2 MPa. This membrane has the potential to separate propylene and ethylene in industry, and this work will push forward the membrane separation process for olefin production.

Gd3+ Complexes Conjugated to Cyclodextrins: Hydroxyl Functions Influence the Relaxation Properties

In the search for improvement in the properties of gadolinium-based contrast agents, cyclodextrins (CDs) are interesting hydrophilic scaffolds with high molecular weight. The impact of the hydrophilicity of these systems on the MRI efficacy has been studied using five beta-CDs substituted with DOTA or TTHA ligands which, respectively, allow for one (q = 1) or no water molecule (q = 0) in the inner coordination sphere of the Gd3+ ion. Original synthetic pathways were developed to immobilize the ligands at C-6 position of various hydroxylated and permethylated beta-CDs via an amide bond. To describe the influence of alcohol and ether oxide functions of the CD macrocycle on the relaxation properties of the Gd3+ complexes, H-1 Nuclear Magnetic Relaxation Dispersion (NMRD) profiles, and O-17 transverse relaxation rates have been measured at various temperatures. The differences observed between the hydroxylated and permethylated beta-CDs bearing non-hydrated GdTTHA complexes can be rationalized by a second sphere contribution to the relaxivity in the case of the hydroxylated derivatives, induced by hydrogen-bound water molecules around the hydroxyl groups. In contrast, for the DOTA analogs the exchange rate of the water molecule directly coordinated to the Gd3+ is clearly influenced by the number of hydroxyl groups present on the CD, which in turn influences the relaxivity and gives rise to a very complex behavior of these hydrophilic systems.
