Surface Color Variations of Ground Beef Packaged Using Enhanced, Recycle Ready, or Standard Barrier Vacuum Films

With current meat industry efforts focused on improving environmental influencers, adopting sustainable packaging materials may be an easier transition to addressing the sustainability demands of the meat consumer. With the growing popularity of vacuum-packaged meat products, the current study evaluated instrumental surface color on fresh ground beef using vacuum packaging films, recycle-ready film (RRF), standard barrier (STB) and enhanced barrier (ENB). Ground beef packaged using ENB barrier film was lighter (L*), redder (a*) and more vivid (chroma) than all other packaging treatments during the simulated display period (p < 0.05). By day 12 of the simulated retail display, the ground beef surface color became lighter (L*), more yellow (b*), less red (a*), less vivid (chroma) and contained greater forms of calculated metmyoglobin, oxymyoglobin (p < 0.05). The current results suggest that barrier properties of vacuum packaging film for ground beef are pivotal for extending the surface color during fresh shelf-life conditions.

Oroonoko: Post-colonialism, Kant and Todorov

Postcolonial theory looks at history, and it links to culture, sociology, psychology, and even politics and law. This study aims to analyze Aphra Behn Oroonoko with respect to post-colonialism, in particular, investigation of the extent colonialism, slavery, and being other. Oroonoko displays literary fiction and reality at the same time; thus, Immanuel Kant’s concepts of the noumenal world and phenomenal world have significant meaning. It draws on these theories and worlds: while the phenomenal world is day-to-day life conditions, the noumenal world is impossible to experience. On the other hand, Tzvetan Todorov’s perspectives on stories and novels are different, and he puts them in scales such as fantastic, uncanny and marvelous. For Oroonoko, readers can decide the scales only if they are willing to understand Todorov’s aims. The aim of this study is to examine Kant's concepts of the noumenal world and the phenomenal world, and Todorov's scales, as well as colonialism, slavery and being other.

Phylogenetic Analysis with Prediction of Cofactor or Ligand Binding for Pseudomonas aeruginosa PAS and Cache Domains

To adjust to a variety of life conditions, bacteria typically use multidomain proteins, where the modular structure allows functional differentiation. Proteins responding to environmental cues and regulating physiological responses are found in chemotaxis pathways that respond to a wide range of stimuli to effect movement.

Low Incubation Temperature During Late Incubation and Early Feeding Affect Broiler Resilience to Necrotic Enteritis in Later Life

Resilient animals can cope with environmental disturbances in life with minimal loss of function. Resilience can be enhanced by optimizing early-life conditions. In poultry, eggshell temperature (EST) during incubation and early feeding are two early-life conditions that are found to alter neonatal chick quality as well as immune response in later life. However, whether these early-life conditions affect disease resilience of chickens at later ages has never been studied yet. Hence, we studied the effects of EST [(37.8°C (control) or 36.7°C (lower)] during late incubation (≥embryonic days 17–19.5) and feeding strategy after hatch [immediately (early feeding) or 51–54 h delayed (delayed feeding)] on later-life broiler resilience in a 2 × 2 factorial arrangement. At hatch, 960 broilers of both sexes from a 54-week-old Ross breeder flock were equally divided over 32 pens (eight replicate pens per treatment combination) and grown for 6 weeks. Necrotic enteritis was induced by a single inoculation of Eimeria spp. at d 21 and repeated Clostridium perfringens inoculation (3×/d) during d 21–25. Mortality and body weight (BW) gain were measured daily during d 21–35 as indicators of resilience. Additionally, disease morbidity was assessed (gut lesions, dysbacteriosis, shedding of oocysts, footpad dermatitis, and natural antibody levels in blood). Results showed a lack of interaction between EST and feeding strategy for the vast majority of the variables. A lower EST resulted in lower BW gain at d 5 and 8 post Eimeria inoculation (P = 0.02) and more Eimeria maxima oocysts in feces at d 8 post Eimeria inoculation compared to control EST (P &lt; 0.01). Early feeding tended to lower mortality compared to delayed feeding (P = 0.06), but BW gain was not affected by feeding strategy. Morbidity characteristics were hardly affected by EST or feeding strategy. In conclusion, a few indications were found that a lower EST during late incubation as well as delayed feeding after hatch may each impair later-life resilience to necrotic enteritis. However, these findings were not manifested consistently in all parameters that were measured, and conclusions are drawn with some restraint.

SATISFACTION WITH LIFE AND HUMAN NEEDS FULFILLMENT

The two notions discussed in the paper are Life Satisfaction, under Subjective Well-Being (SWB) field; and Maslow hierarchy of human needs. Issue: Human needs satisfaction is not an all-or-nothing phenomenon. Individuals are not required to completely satisfy one need in order for the next need to appear in the hierarchy. Purpose: This paper aims to investigate the level of life satisfaction in relation to the difficulty and convenience of achieving human needs. Approach: Mann Whitney U-Tests were conducted to determine the mean of SWL across difficulty and convenient of fulfilling 24 human needs. These human needs are the necessities and life conditions commonly and widely struggled for. Findings: The ease with which the majority of human needs can be met increases life satisfaction significantly. The findings also revealed that for five human needs for which life satisfaction did not differ significantly, meeting these human needs was unlikely to influence life satisfaction. Maslow's Hierarchy of Needs classified these needs as biological and physiological needs, safety and security needs, and esteem needs.

Field evaluation of specificity and sensitivity of a standard SARS-CoV-2 antigen rapid diagnostic test: A prospective study at a teaching hospital in Northern Ghana

The testing capacity for SARS-CoV-2 in Africa is rather limited. Antigen detection rapid diagnostic tests (Ag-RDTs) are a cheap and rapid alternative to reverse transcriptase-polymerase chain reaction (RT-PCR) tests, but there is little data about their performance under real life conditions in tropical countries. The objective of this study is to evaluate the performance of a standard Ag-RDT in a population of a major hospital in northern Ghana. Prospective, cross-sectional, blinded verification of the performance of the SD Biosensor Standard Q SARS-CoV-2 Ag-RDT under real life conditions in 135 symptomatic patients and 58 contacts of RT-PCR positives at Tamale Teaching Hospital in February 2021. Nasopharyngeal samples were taken under standard conditions and tested against RT-PCR in the hospital laboratory. 193 participants (median age 35 years, 109 male) were included into the study for which both RT-PCR test and Ag-RDT results were available. A total of 42 (22%) were RT-PCR positive. Of the 42 RT-PCR positives, 27 were Ag-RDT positive, resulting in a sensitivity of 64% (95% CI 49–79). Sensitivity among symptomatic patients was 58% (95% CI 38–78). 123 were identified Ag-RDT negatives of the 151 RT-PCR negatives, resulting in a specificity of 81% (95% CI 75–87). SARS-CoV-2 Ag-RDTs appear to have a rather low sensitivity and particularly a low specificity under real life conditions in Africa. The role of existing Ag-RDTs in countries with high-temperature climates and limited resources still needs more data and discussion.

Exploring Thematic Progressions in Two Excerpts From Amma Darko’s Faceless

This study explores thematic progressions in two excerpts from Amma Darko’s Faceless. The study aims at looking into the different types of thematic progressions used in the selected excerpts to decode there-from the deep meanings linguistically encoded by the author. The study further aims at examining how the different thematic progressions used in the studied texts contribute to their cohesion and contextual coherence. The research appeals to the mixed quantitative and qualitative methodology. Via this method, the number of thematic progression patterns identified has been quantified per excerpt to pave the way to the interpretation of the findings that ensued. The study has arrived at impressive results. Among several others available in the interpretation of the findings subsection, Amma Darko has purposefully not used the Split-Rheme Pattern to avoid a complex writing style that would make her writing not accessible to her readership. The simple linear thematic progression and the overriding theme reiteration patterns extensively used in both texts have allowed the author to emphasize the key thematic points of the studied texts. Moreover, the theme reiteration development strategy used in both texts has provided them with clear focuses. Some of these include skin bleaching, tradition and marriage in Africa, street children, women’s life conditions in Ghana to name but a few. For deeper meanings decoding in the studied excerpts, further studies on discourse-semantics, contextual coherence, conjunctive and lexical relations, as well as experiential and interpersonal meanings could pick up from this article findings.

Clinical evaluation of UrgoStart Plus dressings in real-life conditions: results of a prospective multicentre study on 961 patients

Aims: This study aimed to evaluate the performances of lipid colloid technology with nano-oligosaccharide factor (TLC-NOSF) dressings with polyabsorbent fibres in an unselected population of patients under real-life conditions. Methods: A large, prospective, multicentre, observational study with three polyabsorbent TLC-NOSF dressings (UrgoStart Plus Pad, UrgoStart Plus and UrgoStart Plus Border, Laboratoires Urgo, France) was conducted in Germany between January 2019 and June 2020. Main outcomes included wound healing rate, clinical assessment of wound healing progression, local tolerance and acceptance of dressings, and changes in health-related quality of life (HRQoL) of the patients, assessed with the validated Wound-QoL questionnaire. Results: A total of 961 patients with wounds of various aetiologies (leg ulcers (LU), diabetic foot ulcers (DFU), pressure ulcers (PU) and other types of wounds) were treated with the evaluated dressings in 105 centres for a mean duration of 62 days (standard deviation 37 days). By the last visit, a wound closure or an improvement in wound healing was reported in 92.0% of the treated wounds. The highest wound closure rates were achieved when the dressings were used as first-line treatment: 71.3% in DFUs, 52.9% in LUs, 53.6% in PUs and 61.8% in the other wounds. Improvement of the wound healing process was also associated with an 87.5% relative reduction of sloughy tissue, a decrease of the level of exudate in 68.9% of the wounds, and an improvement in the periwound skin condition in 66.4% of the patients at the final visit. The dressings were ‘very well’ or ‘well’ tolerated and ‘very well’ or ‘well’ accepted by the large majority of patients. The HRQoL questionnaires were completed both at initial and final visits by 337 patients, representative of the total cohort. Despite the relatively short duration of the wounds, the HRQoL of the patients was already impaired at baseline, with 81.6% of the patients being severely affected in at least one aspect of their HRQoL. By the final visit, significant improvements in each dimension of the patients' HRQoL were reported (p<0.001), along with a reduction of the proportion of patients in need of intervention and in the number of actions needed per patient in relation to their HRQoL. Conclusions: These results are consistent with previous clinical evidence on TLC-NOSF dressings. They confirm the good healing properties and safety profile of these dressings, and that a significant improvement in patient HRQoL is achieved in non-selected patients treated in real-life practice. These data support the use of such dressings as a first-line intervention and until wound healing in the management of chronic wounds, in association with appropriate standard of care.

Changes in Daily Life Conditions among Korean Older Adults after COVID-19 Outbreak

The pandemic of COVID-19 has had a significant impact on peoples’ daily life conditions. Therefore, it is worth understanding changes in daily life conditions among older adults after COVID-19 outbreak. This study was aimed to explore the impact of the pandemic on daily life conditions among Korean older adults. To achieve this aim, an online survey was conducted during April, 2021 to include 184 Korean adults aged 60 years or older nationwide. The results are as follows. First, about 54.9% older Koreans reported that their daily life has stopped since COVID-19. Second, the top 3 increased daily life conditions were spending time at home (77.2%), using internet (60.3%), and shopping online (51.6%). Third, the top 3 decreased daily life conditions were traveling (90.2%), meeting with friends (90.2%), and meeting with family members (80.4%). Fourth, the top 3 daily life conditions with no change were sleeping time (72.3%), eating instant food (58.2%), and household income (53.8%). These findings suggest that several daily life conditions changed after COVID-19 outbreak. Further study is needed to examine the impact of these changes on physical and mental health among older adults.

WLS-ILIAD: Initial Lifetime’s Impact on ADRD

Between 2021 and 2025, WLS will collect two new waves of data, which will capture detailed measures of cognitive change and dementia as the cohort reaches their early to mid 80s. In this session, I will provide an overview of the data that we’re collecting, as well as opportunities to explore early and mid-life determinants of cognitive change and dementia onset in this unique study. Compared to existing studies, the WLS offers some novel opportunities. First, it will provide one of the only opportunities to study how early and midlife life conditions and experiences, on data gathered prospectively, can shape cognitive trajectories and dementia in later life. Second, its unique sibling design provides significant analytic advantages, improving causal inference. Third, the study includes a large group of rural participants, allowing for closer examinations of how rural conditions may shape risk and resilience against cognitive decline and dementia in later life.
