Effects of Teosinte Flour (Dioon mejiae) on Selected Physicochemical Characteristics and Consumer Perceptions of Gluten-Free Cocoa Cookies Formulated with Mung Bean (Vigna radiata) Flour.

Dioon mejiae, or teosinte, is a living fossil tree discovered in Olancho, Honduras, whose seeds have a desirable nutritional profile that can provide health benefits. As a result, the objective of this study was to evaluate the effects of teosinte flour obtained from seeds on selected physicochemical characteristics and consumer perceptions of gluten-free cocoa cookies formulated with mung bean (Vigna radiata) flour. Gluten-free cocoa cookies were prepared with different levels of teosinte flour (0%, 70%, 80%, 90%, and 100% by weight of mung bean flour) in substitution of mung bean flour. The cookies were evaluated for texture hardness, color (L*, a*, b*), moisture content, and water activity. Sensory acceptability of appearance, color, texture, aroma, flavor, and overall quality of cocoa cookies was rated by 175 consumers using a "yes/no" binomial scale. Overall liking was evaluated using a 9-point hedonic scale. Purchase intent was evaluated with a "yes/no" binomial scale. The levels of teosinte flour did not significantly affect the acceptability of appearance, color, texture, flavor, aroma, and overall quality, and neither the overall liking nor the purchase intent responses. However, the texture attribute had the lowest % acceptability response among all sensory attributes. The addition of teosinte flour did not affect water activity and color (L*, a*, b*), whereas it decreased the texture hardness (g force), producing softer cookies. Cocoa cookies stayed acceptable even at 100% teosinte flour addition (70% acceptability; mean overall liking = 5.69). Teosinte flour has an excellent nutritional profile that could be practically applied in baked goods.

Effect of Type of Mulch on Microbial Food Safety Risk on Cucumbers Irrigated with Contaminated Water.

Mulches are used to block light and retain soil moisture which may affect the survival of bacterial pathogens on soil. This study examined the effectiveness of different types of mulches to minimize microbial risk from contaminated water used for irrigation of cucumbers. A production bed of 120 ft2 with 18 beds (30 ft long) covered with five different types of mulch (paper, paper with fertilizer incorporated (PF), maize-based mulch, biodegradable plastic covering, and conventional plastic) including three beds with no cover was planted with Dasher 2 Variety cucumber. Soil samples from each bed were collected for the first five weeks to examine natural E. coli and coliforms. Well water contaminated with or without nalidixic acid-resistant mutant of E. coli (8 Log CFU/mL) was used for drip irrigation for 7 days before harvesting. Prior to irrigation with contaminated water, naturally present E. coli and coliform in the soil samples with or without mulch were in the range of 3.45-3.78 Log CFU/g and 4.18-5.31 Log CFU/g, respectively. E. coli levels on cucumbers harvested from mulched beds and irrigated with contaminated irrigation water had significantly higher (P < 0.05) levels of E. coli as compared with samples from similar beds irrigated with noncontaminated water. However, Cucumber, harvested within each irrigation water quality were not significantly different regardless of the type of mulch with E. coli levels from 1.72 to 3.30 Log CFU/cm2 (contaminated water) and 0.28-1.86 Log CFU/cm2 (noncontaminated water). A significant die-off of inoculated E. coli was observed on cucumber within 3 days (>1.17 Log CFU/cm2) and >1.38 Log CFU/cm2 after 4 days. Beds with maize mulch were effective on minimizing E. coli contamination on cucumber from contaminated irrigation water.

Effect of storage temperature and produce type on the survival or growth of Listeria monocytogenes on peeled rinds and fresh-cut produce.

Whole and fresh-cut produce are minimally processed and susceptible to microbial contamination. This study evaluated the survival or growth of L. monocytogenes on peeled rinds, and fresh-cut produce at different storage temperatures. Fresh-cut fruits and vegetables, including cantaloupe, watermelon, pear, papaya, pineapple, broccoli, cauliflower, lettuce, bell pepper, and kale (25 g pieces) were spot inoculated with 4 log CFU/g of L. monocytogenes and stored at 4 or 13°C for 6 days. Cantaloupe and bell pepper rind disks (20 cm2), mimicking whole produce were inoculated with low inoculum level (4 log CFU/mL) and high inoculum level (6 log CFU/mL) and stored at 24°C up to 8 days and 4°C up to 14 days, respectively. L. monocytogenes counts on fresh-cut pear samples stored at 4°C increased significantly by 0.27 log CFU/g. However, Listeria levels on kale (day 4), cauliflower (day 6), and broccoli (day 2) were significantly reduced by 0.73, 1.18, and 0.80 log CFU/g, respectively, at 4°C. At 13°C, the bacterial counts increased significantly after a day of storage on fresh-cut watermelons (increasing by 1.10 log CFU/g) and cantaloupes (increasing by 1.52 log CFU/g). Similar increases were observed on pears (1.00 log CFU/g), papayas (1.65 log CFU/g), and green bell peppers (1.72 log CFU/g). Pineapple samples did not support the growth of L. monocytogenes at 13°C with a significant reduction of 1.80 log CFU/g by day 6. L. monocytogenes levels significantly increased in fresh-cut lettuce at 13°C but remained stable on kale, cauliflower, and broccoli after 6 days of storage. Stable population was observed also on cantaloupe rinds up to 8 days at 24°C. While on the outer surface of bell peppers, the population level decreased below the detectable limit of the test (10 CFU/20 cm2) after 14 days of storage at 4°C. The results demonstrated variable survival behavior of L. monocytogenes on fresh-cut produce with produce type and storage temperature.

Development of Gluten-Free Bread Using Teosinte (Dioon mejiae) Flour in Combination with High-Protein Brown Rice Flour and High-Protein White Rice Flour.

Gluten-free bread is an important product that is under development using different sources, such as rice and starchy plants. Teosinte seeds are utilized by ethnic groups in Honduras to produce gluten-free flour to prepare traditional baked goods and beverages. The quality of gluten-free products could vary depending on flour properties, such as amylose content, particle size, and water absorption capacity. A good strategy for developing baked goods is to mix different cereal grain sources to optimize their physicochemical properties. As a result, the current study aimed to develop bread from novel flours including teosinte (TF), high-protein brown rice (BRF), and high-protein white rice (WRF). Breads were analyzed for hardness, specific volume, and color utilizing a Simplex-Centroid mixture design coupled with the desirability function. Pasting, and rheological characteristics of the flours, were also analyzed. For flour characteristics, TF addition to BRF or WRF decreased the peak, trough, breakdown, setback, and final viscosities, which would result in a more stable bread and decrease the flow index of rice flour dispersions. BRF and WRF had similar pasting properties, except that BRF had a lower breakdown viscosity. For bread characteristics, TF addition to BRF or WRF increased the specific volume and hardness of the bread compared to rice flour alone. L* of the crust and crumb a* values were increased with greater TF in the mixture, whereas TF decreased the crust a*and b* values and crumb L* values when mixed with BRF or WRF compared to rice flours alone. WRF and BRF were similar in crumb color (L* and a*), except that BRF had greater crumb yellowness (b*). Teosinte flour can be used in combination with rice flour to produce bread with good quality.

High-protein rice flour in the development of gluten-free pasta.

Cahokia Rice, a new biofortified high-protein (10%-12%) variety of rice, was used to develop and analyze a gluten-free pasta. Different pastas were made with high-protein white rice flour (HPWRP), high-protein brown rice flour (HPBRP), commercial white rice flour (CWRP), commercial brown rice flour (CBRP), and wheat flour (WP). Cooking quality of the pasta was evaluated by measuring pasting properties, cooking time, water absorption capacity, and cooking loss. Proximate analysis, color, and texture were done on dry and cooked pasta. Sensory testing was done to determine consumer acceptability and purchase intent of HPWRP and HPBRP in comparison to WP. HPWRP and HPBRP had higher pasting temperatures and lower peak viscosity than commercial rice flour pastas, which was related to the higher protein content. HPWRP and HPBRP had less cooking loss than CWRP and CBRP; all treatments had similar water absorption capacity (∼130%) except for WP that was higher (140%). White rice pastas along with WP took more time to cook than brown rice pastas. HPWRP and HPBRP had higher protein (around 7.5%) and fat content, creating a firmer cooked pasta (138.23 g HPBRP, 179.82 g HPWRP) than commercial rice pastas. Consumers' overall liking of HPBRP (5.37), HPWRP (6.00), and WP (6.81) was acceptable. Color, firmness, and stickiness attributes negatively affected the overall liking of HPWRP and HPBRP. Cooked high-protein rice flour pastas had improved firmness and cooking loss closer to wheat resulting in an acceptable product in overall liking. It is recommended to further improve the color, firmness, and stickiness of the pasta to reach higher sensory acceptability. PRACTICAL APPLICATION: This research provides a possible use for a new high-protein rice flour that can be used in gluten-free products. This will help the rice industry by adding value to the product. Those persons who are Celiac or who desire more nutritional gluten-free products will have a healthier gluten-free pasta option.

Total Utilization-Upcycling of Mushroom Protein By-Product: Characterization and Assessment as an Alternative Batter Ingredient for Fried Shrimp.

Mushroom by-products are economical and eco-friendly raw materials with bioactive and functional characteristics that allow for potential uses as food ingredients. However, mushroom upcycling has yet to be fully exploited, despite the many opportunities that mushrooms may offer. The mushroom protein by-product (MPBP) resulting from mushroom protein production was characterized (chemical composition, physicochemical attributes, and functional properties) and incorporated into plant-based batter formulations to prepare four experimental groups with different ratios (w/w, %) of wheat flour (W) to MPBP (100 W, 75 W/25 MPBP, 25 W/75 MPBP, and 100 MPBP). Subsequently, the batter was used for frying batter-coated shrimp, which was evaluated for cooking loss, coating pick-up, oil absorption, and color parameters (L*, a*, and b*). MPBP showed high content of dietary fiber, mainly insoluble fiber (49%), and it is potentially suited for the formulation of high-fiber food products. The MPBP physicochemical attributes pH (11.69), water activity (0.34), L* (58.56), a* (5.61), b* (18.03), and particle size distribution (250-500 µm (22.12%), 125-250 µm (41.18%), 63-125 µm (37.53%), and < 63 µm (0.82%) were noted. Concerning the MPBP functional characteristics, solubility (12.7%), emulsifying activity index (7.6 m2/gr), emulsion stability index (52.4 min), water holding capacity (4.9%), and oil holding capacity (4.8%) were reported. Adding MPBP into batter formulations for batter-coated shrimp resulted in higher values of cooking loss, oil absorption, coating pick-up, and a* color, while lowering L* and b* values. The best experimental results were reported for group 75 W/25 MPBP, which indicates that MPBP can potentially be accepted as a novel batter ingredient for partial substitution of wheat flour.

Novel Liquor-Based Hot Sauce: Physicochemical Attributes, Volatile Compounds, Sensory Evaluation, Consumer Perception, Emotions, and Purchase Intent.

Hot sauces are popular peppery condiments used to add flavor and sensory excitement to gastronomical preparations. While hot sauce occupies a retail category well over a century old, a novel production method using liquor as the base preservative rather than traditional vinegar is now commercially available, and its uniqueness begs study. Hot sauces produced with tequila, rum, vodka, and bourbon were compared to traditional vinegar-based hot sauces concerning physicochemical properties, volatile compounds, microbiological quality, sensory scores, emotions, and purchase intent (PI). Under accelerated conditions, pH, titratable acidity (TA), water activity (Aw), viscosity, and color were analyzed weekly for 20 weeks, whereas rheological properties, coliforms and yeasts and molds were examined on weeks 1 and 20. Hexyl n-valerate, butanoic acid, 3-methyl-, hexyl ester, and 4-methylpentyl 3-methylbutanoate were found in high concentrations in the pepper mix as well as the hot sauce produced with vinegar. When compared to vinegar-based hot sauces, liquor-based hot sauces had similar Aw (p > 0.05), higher pH, viscosity, and L* values and lower TA, a*, and b* values (p < 0.05). Samples formulated with liquors increased the relaxation exponent derived from G' values having a greater paste formation when compared to vinegar-based hot sauces. The sensory evaluation was carried out in Honduras. The liquor-based hot sauces had a significant (p < 0.05) impact on emotion and wellness terms. Bourbon and tequila samples had higher ratings than control samples in several wellness and emotion responses (active, energetic, enthusiastic, good, curious, pleased, stimulated, and wild). Adventurous, joyful, free, worried, refreshed, and healthy scores were not significantly (p > 0.05) different among treatments.

Effectiveness of Aqueous Chlorine Dioxide in Minimizing Food Safety Risk Associated with Salmonella, E. coli O157:H7, and Listeria monocytogenes on Sweet Potatoes.

Sodium hypochlorite (NaOCl) is a commonly used sanitizer in the produce industry despite its limited effectiveness against contaminated human pathogens in fresh produce. Aqueous chlorine dioxide (ClO2) is an alternative sanitizer offering a greater oxidizing potency with greater efficacy in reducing a large number of microorganisms. We investigated the effect of aqueous chlorine dioxide treatment against human pathogens, Salmonella, Escherichia coli O157:H7, and Listeria monocytogenes seeded on sweet potatoes. Sweet potatoes were spot inoculated (4.2 to 5.7 log CFU/cm2) with multi-strain cocktails of Salmonella spp., E. coli O157:H7, and L. monocytogenes and treated for 10-30 min with 5 ppm aqueous ClO2 or water. Aqueous ClO2 treatment was significantly (p < 0.05) effective in reducing Salmonella with a reduction of 2.14 log CFU/cm2 within 20 min compared to 1.44 log CFU/cm2 for water treatment. Similar results were observed for L. monocytogenes with a 1.98 log CFU/cm2 reduction compared to 0.49 log CFU/cm2 reduction observed after 30 min treatment with aqueous ClO2 the water respectively. The maximum reduction in E. coli O157: H7 reached 2.1 Log CFU/cm2 after 20 min of treatment with aqueous ClO2. The level of the pathogens in ClO2 wash solutions, after the treatment, was below the detectable limit. While in the water wash solutions, the pathogens' populations ranged from 3.47 to 4.63 log CFU/mL. Our study indicates that aqueous ClO2 is highly effective in controlling cross-contamination during postharvest washing of sweet potatoes.

Survival and inactivation of human norovirus GII.4 Sydney on commonly touched airplane cabin surfaces.

Human norovirus (HuNoV) is one of the leading causes of acute gastroenteritis globally. HuNoV outbreaks have been recently reported during air travels. Contaminated surfaces are known as a critical transmission route at various settings. The aim of this study was to provide key information about the survival and the decontamination of HuNoV on three commonly touched airplane cabin surfaces. In this study, we monitored the survival of HuNoV on seat leather, plastic tray table, and seatbelt for 30 days, with and without additional organic load (simulated gastric fluid). The efficacy of two EPA registered anti-norovirus disinfectants were also evaluated. Results showed that HuNoV was detected at high titers (>4 log10 genomic copy number) for up to 30 days when additional organic load was present. Both tested disinfectants were found highly ineffective against HuNoV when the surface was soiled. The study showed that when the organic load was present, HuNoV was highly stable and resistant against disinfectants. Findings from this study indicated that appropriate procedures should be developed by airline companies with the help of public health authorities to decrease passengers' exposure risk to HuNoV.

Improving efficiency within a trauma nurse practitioner team.

BACKGROUND: Clinicians, including nurse practitioners (NPs), face a number of challenges in delivering high-quality care including frequent interruptions that can potentially compromise patient safety and job satisfaction. LOCAL PROBLEM: Trauma NPs voiced frustration with their efforts to provide efficient, high-quality care with frequent interruptions, most commonly pager alerts. The purpose of this quality improvement (QI) initiative was to increase trauma NPs' perceptions of patient safety and improve NPs' job satisfaction by reducing workflow interruptions. METHODS: The Model for Improvement guided this initiative. INTERVENTIONS: The aims of this initiative were to reduce the percentage of nonurgent workflow interruptions via pager alerts by 20% and to increase the utilization of a standardized trauma NP patient rounding process from 0% to 50%. RESULTS: Use of the standardized rounding process improved from 0% to 87%. Interruptions via pager alerts decreased by 36.2%. All nine (100%) trauma NP survey responses revealed an improvement in NP perception of patient safety and job satisfaction. CONCLUSION: The QI initiative found that increasing communication during rounds by using a standardized rounding process involving the bedside registered nurse can minimize interruptions and improve the efficiency of a trauma NP team. The key to the success of the QI initiative was the implementation of a standardized rounding process.

High-protein rice flour in the development of gluten-free muffins.

Gluten-free (GF) products are on the rise due to their perceived healthiness. Hypoallergenic rice flour is typically used in GF products. New rice varieties with greater protein were recently developed. Physicochemical and sensory properties of white and brown high-protein rice flours (HPRFs) and muffins were compared to commercial rice flours. Sensory color of white high-protein rice muffin was favored. Other attributes were not statistically different between samples. HPRF muffins had greater frequencies of "just about right" levels for muffin crumbliness, moistness, and softness than the commercial control. Purchase intent was greater for both HPRF muffins than commercial brown rice muffins. Purchase intent increased further by 9% to 12%, after information that the products were gluten free and made with naturally higher protein rice flour was displayed. This information could be used to market GF food products if increased protein ingredient claims are included. PRACTICAL APPLICATION: This study shows that greater protein content rice flour can be used to make gluten-free (GF) muffins that are acceptable to consumers. Analysis and application of higher protein rice flours could contribute to a large-scale use in GF baked goods that may aim to naturally increase nutritional value. This research also shows that purchase intent increases when the greater protein content and gluten free is stated. This information can be used for GF product development and marketing of these products.

Survival and inactivation of Salmonella enterica serovar Typhimurium on food contact surfaces during log, stationary and long-term stationary phases.

One of the most important transmission routes of foodborne pathogens is through contaminated food contact surfaces. In this study, we investigated the survival and inactivation of Salmonella enterica serovar Typhimurium on frequently used food contact surfaces in household settings, including plastic cutting board (CB), formica laminate (LA), and stainless steel (SS) surfaces. S. Typhimurium at log (6 h), stationary (24 h), or long-term stationary (LTS) (14 days) phases were evaluated. Results showed that, at medium and high microbial loads, LTS phase cells had significantly higher survivor population compared to log and stationary phase cells at 24 h after inoculation (p < 0.05). Disinfection study showed that LTS phase cells were very resilient to sodium hypochlorite when the initial microbial load was high with disinfection efficacy ranging from 26 to 35%. Scanning electron microscopy of these surfaces at 24 h after inoculation with a high microbial load revealed an early biofilm structure.

Effect of bambara groundnut supplementation on the physicochemical properties of rice flour and crackers.

This study evaluated the effect of bambara groundnut supplementation on the physicochemical properties of local rice flour and baked crackers. Bulk and true density, porosity, water absorption index, oil absorption capacity, pasting properties by RVA, morphological appearance by SEM, color by calorimetry, and textural properties by TA.XT2 analysis of wheat and two formulations of rice-legume flours and crackers were studied. Moisture (10.94%) and carbohydrate (77.42%) levels were significantly greater in wheat flour than the rice-legume flours, while the reverse was true for fat and ash. Also rice-legume flours had significantly greater water and oil absorption capacity and lower water solubility compared to wheat flour. Compared to wheat crackers, rice-legume crackers had greater fat and ash, 20.51 and 3.57%, respectively, while moisture was significantly lower in the rice-legume crackers by 41 to 58%. Rice legume crackers were significantly harder and had significantly increased spread ratio. The results obtained from the development of locally grown rice and underutilized legume bambara groundnut showed great promise in physicochemical and functional properties and may be a good replacement for wheat flour to serve as a gluten-free product.

Impact of the acute care nurse practitioner in reducing the number of unwarranted daily laboratory tests in the intensive care unit.

BACKGROUND: Frequent laboratory testing may be necessary at times for critically ill patients. However, the practice of indiscriminate laboratory test ordering is common. PURPOSE: The purpose of this quality improvement project was to assess the effectiveness of the acute care nurse practitioner (ACNP) in reducing the number of unwarranted laboratory tests ordered for ICU patients. To determine whether the presence of an ACNP would make a difference, an ACNP was present on daily ICU multidisciplinary rounds to facilitate the discussion of the laboratory testing needs for each patient for the following 24-hour period. CONCLUSIONS: Eighty-one patients were enrolled in the project, 41 in the comparison and 40 in the intervention group. No significant differences were noted between the two groups. The project demonstrated that although there was an increase in tests ordered for the intervention group, the increase was brought about by an increase in specific individual tests rather than an increase in panels of laboratory tests. A reduction in patient cost was observed for the number of tests ordered. No increase in adverse events was noted. IMPLICATIONS FOR PRACTICE: Acute care nurse practitioner presence on multidisciplinary rounds may be an effective method to change the practice toward the ordering of tests based on clinical indication.

Challenges of Designing and Implementing High Consequence Infectious Disease Response.

Ebola is a high consequence infectious disease-a disease with the potential to cause outbreaks, epidemics, or pandemics with deadly possibilities, highly infectious, pathogenic, and virulent. Ebola's first reported cases in the United States in September 2014 led to the development of preparedness capabilities for the mitigation of possible rapid outbreaks, with the Centers for Disease Control and Prevention (CDC) providing guidelines to assist public health officials in infectious disease response planning. These guidelines include broad goals for state and local agencies and detailed information concerning the types of resources needed at health care facilities. However, the spatial configuration of populations and existing health care facilities is neglected. An incomplete understanding of the demand landscape may result in an inefficient and inequitable allocation of resources to populations. Hence, this paper examines challenges in implementing CDC's guidance for Ebola preparedness and mitigation in the context of geospatial allocation of health resources and discusses possible strategies for addressing such challenges.

Application of Edible Films Containing Oregano (Origanum vulgare) Essential Oil on Queso Blanco Cheese Prepared with Flaxseed (Linum usitatissimum) Oil.

Fortification of queso blanco (QB) with flaxseed oil (FO) containing omega-3 polyunsaturated fatty acids may provide a functional food with health benefits such as improved cell, brain, and retina functionality, and protection against cardiovascular and immune-inflammatory diseases. However, QB experiences a short shelf life because of the early development of yeasts and molds and addition of FO may increase susceptibility to lipid oxidation. Oregano essential oil (OEO) is known for its antimicrobial and antioxidant properties, but due to its intense flavor compounds it may not be suitable for direct incorporation into QB. Thus, incorporation of OEO into an edible film prepared with whey protein isolate (WPI) may improve the shelf life of QB. Scanning electron microscopy (SEM) micrographs revealed that FO was successfully retained by the cheese after homogenization. The thiobarbituric-acid-reactive-substances (TBARS) and yeast and mold counts (YMC) of the wrapped cheeses were analyzed during 60 d of refrigerated storage. The oxidation rate increased significantly for nonwrapped QB containing FO (QBFO) during storage, however wrapping with WPI edible films containing OEO (WOF) significantly limited lipid oxidation and prevented growth of yeasts and molds. This study demonstrated the antioxidant and antimicrobial properties of WOF for preservation of QBFO during refrigerated storage.

Chest pain: a time for concern?

When a patient complains of chest pain, the first priority is to establish whether the situation is life threatening. Life-threatening differential diagnoses that clinicians must consider include acute coronary syndrome, cardiac tamponade, pulmonary embolus, aortic dissection, and tension pneumothorax. Nonthreatening causes of chest pain that should be considered include spontaneous pneumothorax, pleural effusion, pneumonia, valvular diseases, gastric reflux, and costochondritis. The challenge for clinicians is not to be limited by "satisfaction of search" and fail to consider important differential diagnoses. The challenge, however, can be met by developing a systematic method to assess chest pain that will lead to the appropriate diagnosis and appropriate treatment plan.

ACNP intensivist: a new ICU care delivery model and its supporting educational programs.

The purposes of this article are to describe a physician (MD)/acute care nurse practitioner (ACNP) intensivist model for delivery of critical care services in a tertiary academic medical center and to describe an innovative nurse practitioner educational program developed to support the model. In an effort to address the current shortage of intensivists, Vanderbilt Medical Center has developed and refined a multidisciplinary intensivist MD/ACNP teams to provide expanded critical care services. The ACNPs, in collaboration with intensivist MDs, function as intensivist teams and are responsible for developing and executing the daily medical plan, bedside procedures, and emergency response. These teams provide 24-h a day coverage of tertiary level ICUs, and provide several unique benefits over traditional resident ICU staffing models. As the concept of the MD/ACNP intensivist team has developed, Vanderbilt University School of Nursing ACNP Program has expanded its curriculum to provide graduates with the knowledge, skills, and experiences to safely manage unstable critically ill patients. Multidisciplinary critical care teams of MD intensivists who work in collaboration with ACNP intensivists address the current shortfall of intensivists and represent a cost-effective means for expanding ICU coverage and increasing ICU bed availability while maintaining Leap Frog ICU staffing compliance.

Comparison of the activities of hydrophilic anthocyanins and lipophilic tocols in black rice bran against lipid oxidation.

The antioxidant capabilities of anthocyanin and tocol extracts from black rice bran were evaluated using an emulsion system containing either cholesterol (1.0mg/ml) or fish oil (10mg/ml). The cholesterol oxidation product, 7-ketocholesterol, increased to 180.1 µg/ml in the control emulsion after 168 h of oxidation, while it was only 15.4 and 39.0 µg/ml in the emulsions containing 1 µg/ml of the anthocyanin and tocol extracts, respectively; but below 1.2 µg/ml in the emulsion having 5 µg/ml of anthocyanins or tocols. In the fish oil emulsion, over 80% of C20:5 and C22:6 were oxidised after a 48 h incubation at 37°C, while they were retained above 38% and 65% in the emulsions containing 10 µg/ml of anthocyanins and tocols, respectively, and above 85% in the emulsion containing 20 µg/ml of anthocyanins or tocols. Compared with the tocols extract, the capability of the anthocyanin extract was relatively greater in stabilising cholesterol but lower in inhibiting fatty acids oxidation.

Championing person-first language: a call to psychiatric mental health nurses.

At the heart of recovery-oriented psychiatric mental health care are the dignity and respect of each person and the ways in which helping professionals convey a person's uniqueness, strengths, abilities, and needs. "Person-first language" is a form of linguistic expression relying on words that reflect awareness, a sense of dignity, and positive attitudes about people with disabilities. As such, person-first language places emphasis on the person first rather than the disability (e.g., "person with schizophrenia" rather than "a schizophrenic"). This article champions the use of person-first language as a foundation for recovery-oriented practice and enhanced collaborative treatment environments that foster respect, human dignity, and hope.
