Interactions between Storage Temperature and Ethanol that Affect Growth of Brettanomyces bruxellensis in Merlot Wine

The potential for synergy between temperature and ethanol as a means to control infections by Brettanomyces bruxellensis in red wines was studied. Using a commercially prepared Merlot wine, we employed a 4 × 5 factorial experimental design with storage temperature (12, 15, 18, or 21°C) and ethanol (12, 13, 14, 15, or 16% [v/v]) as variables. Culturabilities of two B. bruxellensis strains (I1a and F3) isolated from Washington wines (I1a and F3) were monitored for 100 days before concentrations of volatile acidity, 4-ethylphenol (4-EP), and 4-ethylguaiacol (4-EG) were quantified. While growth of both strains was observed in 12 to 15% (v/v) ethanol, lag phase duration generally increased with a decrease in temperature. The two strains displayed similar growth patterns under the various temperature × ethanol conditions, except in the wines containing 15% (v/v) ethanol. At this concentration, F3 exhibited less growth and reduced concentrations of volatile acidity, 4-EP, and 4-EG at the higher temperatures (18 and 21°C) than did I1a. In fact, F3 grew better at 18°C than at 21°C at 15% ethanol. Culturabilities of both strains quickly declined in wines containing 16% v/v ethanol. Wines in which B. bruxellensis reached >106 cfu/mL frequently contained concentrations of 4-EP and 4-EG in excess of 1290 and 155 μg/L, respectively, and thus above the olfactory thresholds for the two compounds. Given the significant interactions between temperature and ethanol, wines containing >13% (v/v) ethanol should be stored at ≤12°C to help limit spoilage by this yeast.
Inhibition of Polymer Photodegradation by Incorporation of Coffee Silverskin

Over the last years, the trend associated with the incorporation of materials from renewable resources into polymer technology is getting significantly more vital. Researchers are trying to transfer the properties of natural raw materials into the polymer world. Therefore, different natural materials are more often investigated as potential additives for polymers. Such an effect is noted for the coffee industry by-products, such as coffee silverskin. Because of the relatively high contents of compounds showing antioxidant activity, such as caffeine, polyphenols, tannins, or melanoidins, this by-product could be considered not only as a filler, but also as a potential modifier for polymer materials. Its antioxidant activity is comparable to commercially available antioxidants applied in polymer technology. Therefore, in the presented paper, we examined the influence of the coffee silverskin (from 1 to 20 wt%) on the thermal and mechanical performance of polyethylene-based composites. Moreover, materials were subjected to accelerated aging tests in the UV chamber, which revealed that coffee silverskin could inhibit the photodegradation of the polymer matrix. Therefore, this by-product should be considered as an exciting alternative for the conventional lignocellulosic fillers, which could provide additional features to polymer composites.
Fit for Surgery – Effects of short-course multimodal individualized prehabilitation in high-risk frail colon cancer patients prior to surgery: A feasibility study

Background Prehabilitation is a promising modality for improving patient-related outcomes after major surgery, however, very little research has been done for those who may need it the most; the elderly and the frail. The study aimed to investigate if high risk, frail patients with colorectal cancer and WHO performance status I and II could adhere to a short course multimodal prehabilitation intervention prior to surgery.Methods The study was conducted as a single-center, prospective one-arm feasibility study with limited-efficacy testing of eight patients. The intervention consisted of a physical training program tailored to the patients with both high-intensity interval training and resistance training three times a week, nutritional support with protein and vitamins, a consultation with a dietician, and medical optimization prior to surgery. The primary outcomes were the increase in maximum oxygen intake (VO2 peak) during the intervention and per-protocol compliance and adherence. Secondary outcomes were: increase in body weight, increase in albumin, adverse events during the intervention, postoperative length of stay, and complications within 30 days after surgery. Results The mean age vas 80 (range: 66-88). Seven completed the intervention. The mean increase in maximum oxygen intake (VO2 peak) was 17 % (range: 0.6% - 28 %), with two patients being non-responders. All patients who had a prediagnostic weight loss increased their body weight with a mean of 2.5 kg (range: 1.3 – 4.0 kg). Adherence to high-intensity interval training was 87 %, whereas adherence to nutritional support was 57 %. The median postoperative length of stay was 3 days (range: 1-26). Conclusions This one-arm feasibility study indicates that multimodal prehabilitation including high-intensity interval training can be performed with high adherence to the program in patients with colorectal cancer and WHO performance status I and II Clinical trial registration Clinicaltrials.gov: NCT04167436, Date of registration November 18 2019. Retrospectively registered.
Life in the army reserves – the balance of work, training and physical activity: an ethnographic study

ABSTRACT Physiological, psychological and social risk factors influence the health and wellbeing of military personnel and units. Whilst evidence has investigated employment within the regular military, the same cannot be said for reserve personnel. Reservists negotiate civilian employment whilst balancing the rigours of military life. Little is known about the lives and experiences of these individuals despite their reliance within the military. The current study sought to understand the health, lives and experiences of reservists through an ethnography consisting of observations, lived experience, conversations and semi-structured interviews. Forty personnel participated in the study which took place in one combat unit of the British Army. Data were collected across training exercises and weekly meetings. In total 300 hours of data were analysed using an iterative process. ‘Life as a reservist’, ‘the risk factors and implications for health and wellbeing’ and ‘the critical promotion of physical activity and health within the Army’ were identified within the data. While the training the Army Reserves undertake is supportive of health and wellbeing, the structure within the Army reduces choice and control. Enriching training and social support can mitigate these antecedents of ill-being. Further effective training can provide a setting to foster resilience and prepare personnel for deployment. The study highlights the differences and similarities between full-time personnel and the experiences of reservists, both in terms of health, wellbeing and the training undertaken. Future research may seek to understand the differences in theatres of operation, and attitudes of those responsible for promoting health and wellbeing.
Identification of vegetal species in wooden objects using in situ microextraction-assisted voltammetry of microparticles

A method for identifying vegetal species in wooden objects using microextraction-assisted voltammetry of microparticles is described. The proposed methodology, aimed at facilitating tasks of patrimony conservation, is based on the recording of the voltammetric response of microparticulate films of compounds resulting from microextraction with organic solvents (ethanol, acetone, and chloroform) of micro- or sub-microsamples of wood in contact with aqueous buffers. Upon application of bivariate and multivariate chemometric techniques, the obtained voltammetric responses led us to identify different taxonomic groups from the characteristic voltammetric profiles. Application to a series of samples of wooden objects of cultural heritage of different European and American provenances dated to ca. 375–350 BC and to historical periods, namely 14th and 17–19th centuries, is described.
When Sentiment Is News: The Polarity Pattern Approach

We present a new approach and set of dictionaries for the analysis of sentiments in financial and business news headlines at the firm level. The proposed Polarity Pattern Approach (PPA) captures the deep structure of context and syntax and reduces measurement errors evident in previous approaches for classifying the tone of words and sentences in news headlines. We demonstrate the superior predictive validity of PPA using an out-of-sample dataset. As expected, negative news headlines are negatively related to stock returns and positively related to trading volumes, while positive news headlines are positively related to both, especially for finance news. Prior studies report a non-significant or, counter intuitively, negative relationship between positive news and stock returns, which we attribute to measurement error in previous approaches. Additionally, using market activities, we jointly estimate cross-sectional regression to compare the explanatory power of the PPA approach with commonly used methods. We show how PPA’s tone assignment significantly outperforms other dictionaries and approaches, including the commercial package (RavenPack) that uses both machine learning and deep learning. The PPA, including dictionaries, provides finance researchers with a new, more valid method of sentiment analysis for media news.

Self-perceived Preparedness to Prescribe Antibiotics Among Swiss Medical Students: Results from a Cross-sectional Survey in four Swiss Universities in 2015.

BackgroundPrevious studies have highlighted that medical students do not feel well prepared to prescribe antimicrobials. The ESCMID Study Group for Antimicrobial stewardshiP (ESGAP) conducted a survey among European medical students to assess self-reported preparedness about prudent antibiotic use and the perceived lack of education. The aim of the present study was to specifically focus on the perceptions of Swiss medical students. MethodsA cross-sectional web-based survey was conducted in 2015 by ESGAP involving sixth-year medical students from Switzerland. The survey investigated self-reported preparedness on diagnosis and treatment of infections, availability and perceived usefulness of different teaching methods and the perceived need for further education on antibiotic use. “Preparedness scores” were created by calculating the percentage of students who felt sufficiently prepared on each topic. ResultsWe received responses from 137 medical students from 4 medical schools (Bern, Geneva, Lausanne and Zurich). The overall estimated response rate was 19%. Overall, 62% of Swiss students reported needing more education on antibiotics or at least on their prudent use. Teaching methods perceived as more useful were discussion of clinical cases (80.2%), clinical rotation in infectious diseases (77.0%) and small group teaching (75.0%), but the latter 2 were reported as unavailable for nearly half of the students (36.5% and 47.5%, respectively). Almost all of the students felt sufficiently prepared to recognize clinical signs of infection (99.3%), to interpret inflammation markers (94.9%) and to have sufficient knowledge of consequences of antibiotic misuse (95.5%). Less than half of them felt prepared to select the right empirical treatment without using guidelines (33.8%), to identify the need for combination therapy (39.7%) or to select the shortest adequate treatment duration (39.3%). ConclusionsMost Swiss final year medical students feel they need more education on antibiotics. Some of the teaching methods perceived as more useful by students seem still insufficiently available in Swiss medical schools. Active and interprofessional teaching activities can be a first step towards more effective education on prudent antibiotic use.
Board Cognitive Diversity and Firm Performance Nexus: Evidence From Nigeria

Purpose of the study: This study examined the influence of board cognitive diversity on firm performance in Nigeria. The researchers investigated consumer goods firms listed in the Nigeria Stock Exchange from 2013 to 2018. <br><br>Methodology: This research is hinged on the positivist research philosophy; and the deductive research approach. The study adopted the multi-method quantitative research design. Data was hand-collected from the annual financial statements and firms’ websites of consumer goods firms. The researchers measured board cognitive diversity by educational level diversity, education background diversity, and professional member diversity; while performance was measured via financial performance (ROA) and market performance (Tobin's Q). Panel least squares were used to estimate the model of the study. <br><br>Main Findings: Results from the panel least squares regression revealed mixed findings on the nexus between the proxies of board cognitive diversity and firm performance in Nigeria. Specifically, we found that education level diversity and professional member diversity of board members positively and significantly affects market performance.In contrast, the educational background diversity of the board negatively and significantly affects the market performance of consumer goods firms in Nigeria. Furthermore, we found no evidence on the nexus between educational level diversity; educational background diversity; professional membership diversity of board members, and financial performance of firms investigated. <br><br>Implications/Applications: The researchers concluded that board cognitive diversity partially influences firm performance in Nigeria.The study recommended that firms in Nigeria, specifically consumer goods firms, should encourage more representation of board directors with a postgraduate degree. This is because they have advanced knowledge and expertise to improve the firm's performance.Novelty/Originality of this study: This is pioneer research to investigate the influence of board cognitive diversity on firm performance in Nigeria.
Argon metastable production in argon-helium microplasmas

Microwave resonator-driven microplasmas are a promising technology for generating the high density of rare-gas metastable states required for optically pumped rare gas laser systems. We measure the density of argon 1s5 states (Paschen notation) in argon-helium plasmas between 100 Torr and atmospheric pressure using diode laser absorption. The metastable state density is observed to rise with helium mole fraction at lower pressures but to instead fall slightly when tested near atmospheric pressure. A 0-D model of the discharge suggests that these distinct behaviors result from the discharge being diffusion-controlled at lower pressures, but with losses occurring primarily through dissociative recombination at high pressures. In all cases, the argon metastable density falls sharply when the neutral argon gas fraction is reduced below approximately 2%.

Phenotypic and Molecular Characterization of the Capsular Serotypes of Pasteurella Multocida Isolates From Bovine Respiratory Disease Cases in Ethiopia

Background: Pasteurella multocida is a heterogeneous species and opportunistic pathogen that causes bovine respiratory disease. This disease is one of an economically important disease in Ethiopia. Losses due to mortality and associated expenses are estimated to be higher in the country. Studies revealed that limited information is available regarding the capsular types, genotypes, and antimicrobial sensitivity of P. multocida isolates circulating in the country. This suggests, further molecular advances to understand the etiological diversity of the pathogens representing severe threats to the cattle population. Results: Bacteriological analysis of nasopharyngeal swab and pneumonic lung tissue samples collected from a total of 400 samples revealed isolation of 61 (15.25%) P. multocida subspecies multocida. 35 (20.59%) were isolated from calves and 26 (11.30%) from adult cattle. Molecular analysis using PCR assay targeting KMT1 gene (~460 bp) amplification was shown in all presumptive isolates. Capsular typing also confirmed the presence of serogroup A (hyaD-hyaC) gene (~1044 bp) and serogroup D (dcbF) gene (~657 bp) from 56 (91.80%) and 5 (8.20%) isolates, respectively. The biovar typing identified 48 (78.69%) isolates of biovar 3. Phylogenetic analysis based on the hyaD-hyaC gene nucleotide sequences showed that P. multocida serogroup A are genetically closely related to the different P. multocida isolates retrieved from the GenBank. Antibiogram of isolates revealed high sensitivity towards chloramphenicol (100%), amoxicillin (95.08%), and amikacin (90.16%). Resistance was observed in cloxacillin (88.52%) and Penicillin-G (77.05%). Conclusions: In the present study, P. multocida capsular type A biovar 3 was predominantly isolated from pneumonic cases in cattle in the study areas. The finding provides useful information for further research and choice of antimicrobials for treatment. Hence, further comprehensive molecular epidemiological investigation is proposed covering wider areas of the country to identify pathogens associated with BRD for an effective control strategy.

Background: Chronic kidney failure is a state of progressive, irreversible destruction of kidney structure that requires permanent kidney replacement therapy. Global prevalence is 11.7% -15.1%. Chronic disease conditions and prolonged treatment can affect the patient's mental health and quality of life. The process by which a person attains physical and mental readiness in dealing with stressful situations is called coping. Quality of life is an individual's perception of their position in life. The aim of this study was to determine the relationship between coping mechanisms and quality of life in patients with chronic renal failure undergoing hemodialysis. Method: This research was analytical correlative with cross sectional research design. Sampling with consecutive sampling technique and obtained as many as 35 respondents. The criteria for patients in this study were patients diagnosed with chronic renal failure and undergoing hemodialysis with an age limit of 18 - 65 years, compos mentis awareness status and willingness to become respondents. The study was conducted in November 2019- January 2020. Patient data were obtained through medical records and questionnaires kidney disease quality of life short form (KDQOL-SF) and a brief cope scale. Results: The results of statistical tests obtained p value = 0.007 and r = 0.413 (p <0.05; r> 0.05). These results indicate that there is a relationship between coping mechanisms and quality of life in patients with chronic renal failure undergoing hemodialysis. More male respondents than women with 56-65 years age group, the highest education status is college; working as a civil servant, long undergoing HD 1-12 months. Based on statistical analysis it is known that the coping mechanism of poor respondents (57.1%), poor quality of life (54.3%). Conclusion: There was significant relationship between coping mechanisms with the quality of life of patients with chronic renal failure undergoing hemodialysis with moderate correlation strength and positive direction.
CT and MRI Characteristic Findings of Sporadic Renal Hemangioblastoma: Two Case Reports and Review of the Literature

BackgroundHemangioblastoma in the kidney is rare. Although a few renal hemangioblastoma cases have been reported, the content of these articles mainly focused on clinical and pathological research, with minimal descriptions of radiologic findings. Moreover, there are no descriptions of magnetic resonance imaging with enhancement for this condition. We herein report two cases of renal hemangioblastoma with computed tomography and magnetic resonance imaging findings.Case presentationTwo patients presented to our institution due to dull pain of the left abdomen, and a mass in the left kidney was found by ultrasound examination in each case. They had no special family history. Physical examination revealed no obvious tenderness or percussion pain in the renal region and ureteral walking area, and there was no obvious mass. Routine blood and urine tests were normal, and serum tumor markers were negative. No obvious lesions were found on imaging of other body parts. Similar radiologic findings were observed in both cases and mimicked those of cavernous hemangiomas of the liver, including peripheral nodular enhancement in the corticomedullary phase, progressive centripetal enhancement in the nephrographic and delayed phases, and occasional complete “filling in” in the delayed phase. Given the suspicion for renal cell carcinoma, both patients underwent partial nephrectomy. The pathological results showed renal hemangioblastoma.ConclusionsRenal hemangioblastoma is a rare benign tumor that is easily misdiagnosed as clear cell carcinoma. Characteristic computed tomography and magnetic resonance imaging manifestations may improve preoperative diagnostic accuracy to avoid surgery or indicate nephron-sparing surgery.
