Determination of aflatoxins in coffee by means of ultra-high performance liquid chromatography-fluorescence detector and fungi isolation

ABSTRACT In this study, fourteen coffee samples were collected from local markets in Doha, Qatar according to different variables i.e. packed or unpacked, beans or powder, roasted or raw bean samples. The coffee samples were subjected to both microbiological and chromatographical analyses. The microbiological isolation was achieved using direct plating of the coffee on malt agar extract and potato dextrose agar plates. The chromatographical analytical method was conducted using ultra-high-performance liquid chromatography-fluorescence detector (UHPLC-FLD) to quantify the contamination of four classes of aflatoxins (B1, B2, G1, and G2). In the UHPLC-FLD validation process, no interfering peaks were present and the aflatoxins G1, B1, G2, and B2 were well separated. The R2 or coefficient of determination of the calibration plots for all compounds was ≥ 0.995. The limit of quantitation for all compounds was 2 μg/kg. The precision or the relative standard deviation calculated for six replicates of samples spiked at 2 μg/kg were less than 20%, and the limit of detection was 0.17 μg/kg, 0.14 μg/kg, 0.12 μg/kg and 0.09 μg/kg for Aflatoxins G1, Aflatoxins B1, Aflatoxins G2, and Aflatoxins B2, respectively. The average recovery calculated for six replicates of samples spiked at 2 μg/kg was from 74.5–80%. The results for the chromatographical part showed that there was no contamination of aflatoxin in most of the coffee samples collected. Only two samples exhibited low concentrations of aflatoxin G, which are sample A (4.27 × 10−1 μg/kg) and sample O (1.99 × 10−2 μg/kg). Direct plating showed growth of microorganisms, such as Aspergillus niger, Mucor sp. , Bacillus sp. , Fusarium sp. , and two yeast species. Although some of the isolated species have the potential to produce mycotoxins in coffee, they might be in the spore phase in the coffee samples and did not germinate.
Adherence to the DASH Diet and Risk of Breast Cancer.

BACKGROUND The Dietary Approach to Stop Hypertension (DASH) eating pattern has been recommended as a healthy dietary plan by several international guidelines. However, data on the association between the DASH diet and breast cancer is limited. This study investigated the association between the DASH dietary pattern and risk of breast cancer. MATERIALS AND METHODS This is a hospital-based case-control study conducted between 2014 and 2016 in the Cancer Institute of Iran. Patients with histopathologically confirmed breast cancer were recruited. Controls were healthy subjects who were frequency matched to cases by residential place and age (±10 years). A validated 168-item Food Frequency Questionnaire was applied to assess the dietary intake of participants. Physical activity was assessed using the Global Physical Activity Questionnaire. The DASH dietary pattern scores were calculated using the method introduced by Fung. Unconditional logistic regression, in which potential confounders were taken into account, was applied to determine the association between adherence to the DASH dietary pattern and odds of breast cancer. RESULTS The study participants comprised 477 patients with breast cancer and 507 healthy controls. In the total population, patients with breast cancer were slightly older (45.9 vs. 43.9 years, P = .02), had slightly higher BMI (21.9 vs. 20.2, P = .01) and were less physically active (20 vs. 27 MET h/wk. P < .01) than controls. In Model A, which was adjusted for age and energy intake, adherence to the DASH dietary pattern substantially reduced breast cancer risk in the total population (OR for comparing extreme tertiles: 0.62; 95% CI 0.44-0.78; Ptrend = 0.004). Even after controlling for more cofounders, greatest adherence to DASH diet was associated with a 34% reduction in risk of breast cancer (OR 0.66; 95% CI 0.46, 0.94; Ptrend = 0.03). In premenopausal women, adherence to the DASH dietary pattern was insignificantly associated with a 32% reduction in breast cancer risk. This risk reduction was 38% in postmenopausal women, which was also not found to be significant CONCLUSION: Adherence to the DASH dietary pattern could be associated with an approximately 30% reduction in risk of breast cancer. However, further studies, in particular studies with prospective design, are required to confirm this claim.
Healthcare students’ use of an e-textbook open educational resource on vital sign measurement: a qualitative study

ABSTRACT Students desire free textbooks that incorporate multimedia and interactive experiences. Although there is an increased production of e-textbooks, these resources tend to replicate hard copy books and do not take advantage of the functions that technology offers. There is also a shift to creating e-textbooks that are considered open educational resources. A team of nursing educators and a nursing student created an interactive open educational resource e-textbook in vital sign measurement that was implemented within the curriculum of post-secondary health-related programmes. The goal of this paper is to report the study findings which sought to explore healthcare students’ experiences of using this open educational resource. Three discipline-specific focus groups were conducted with a convenience sample of 29 students. Using a qualitative thematic analysis, six interconnected themes describing students’ use of this resource were identified: (a) This Generation’s Learner, (b) Vital Signs Open Educational Resource influence, (c) Accessibility, (d) Convenience, (e) Design, and (f) Visual and Other Types of Learning Styles. Participants were positive about using the open educational resource to learn vital sign skills. Our study findings provide a foundation for e-textbook design standards that support student learning.
The impact of Project-based organization on competence management practices: Case of Tunisian companies

The present article aimed at studying the relationship between project-based organization and competence management practices (recruitment, assessment, training, compensation and career management). The central question of our research is formulated as follows: To what extent does project-based organization influence competence management practices? To answer this question, we adopted a quantitative study. A total of 156 Tunisian project managers participated in our survey. We tested our hypotheses through a linear regression analysis. The results show that the majority of competence management practices, namely recruitment, evaluation and training, are more relevant to project-based organizations and thus the three first hypotheses are confirmed. However, other practices, like remuneration and career management, are insensitive to project activities.

Knowledge, Attitudes, and Practice among Malaysian in facing COVID-19 During the Implementation of Movement Control Order

Background: The rapid acceleration in the number of hospitalizations and deaths of COVID-19 has attracted global attention and caused worldwide fear. In mid-March 2020, Malaysia has recorded the highest COVID-19 cases in Southeast Asia. As an immediate response, the Malaysian government has imposed Movement Control Order (MCO) to break the chain of infection and slow down the pandemic widespread. By mid-May 2020, R naught in Malaysia is at 0.3 as compared to 3.55 in mid-March 2020. Understanding the public’s knowledge, awareness, and reaction toward COVID-19 during the outbreak in the general population is paramount to give a real picture of the public’s responses in curbing the COVID-19 widespread. This study aims to determine the knowledge, attitude, and practice of social distancing among Malaysians during the COVID-19 outbreak. Methods: This cross-sectional study presents results from 3211 respondents by answering questionnaires through an online survey from 24 - 26 March 2020, one week after MCO was imposed. Responses were summarized using descriptive statistics and Chi-square test (χ²) statistic ware used to test whether the data from two or more groups of categories are associated with social distance practice.Results: Almost half of the respondents have an excellent level of knowledge (47.6%) and a positive attitude (47.4%) towards the COVID-19. Interestingly, more than half of the respondents (67.5%) performed good social distancing practice, while 30% exercised strict social distancing practice. A chi-square test shows that there is a significant association between knowledge and social distancing practice and no significant association between attitudes and social distancing practice. Conclusions: There is no COVID-19 vaccine nor herd immunity obtained yet, therefore the social distancing practice is the effective mechanism adopted to reduce the COVID-19 widespread, and Malaysia has proven it.

Radius of Gyration, Mean Span, and Geometric Shrinking Factors of Bridged Polycyclic Ring Polymers

This study concerns the equilibrium geometric properties of a family of cyclic chains, referred to as the “bridged polycyclic rings,” which have f flexible subchains bridging two common branch points. By increasing the number of bridges, f, this family encompasses the usual linear chain (f = 1), monocyclic ring (f = 2), bicyclic θ-shaped polymer (f = 3), and multicyclic rings with increasing topological complexity. Results of their radius of gyration, mean span, and, consequently, geometric shrinking factors (also known as the g-factors) are obtained by three approaches—the Gaussian chain theory, simulations based on the Kremer–Grest bead-spring model, and a Flory-type mean-field approach. Using the confinement analysis from bulk structures method, the equilibrium partition coefficients (K) of several of those cyclic excluded volume chains in a cylindrical pore with inert surfaces are obtained, and the results fall onto a common curve on a graph of K versus the polymer-to-pore size ratio, using the mean span as the representative polymer size, in the range of K relevant to polymer separation in size exclusion chromatography (SEC) experiments. Applications of the results in predicting the SEC retention volume of such bridged polycyclic ring polymers are discussed in the framework of the equilibrium partition theory.
Effect of drip fertigation levels and plant growth regulators on growth and yield of transplanted redgram (Cajanus cajan)

The field trial was conducted during rabi, 2019 at Water Management Research Block, Department of Agronomy, Agricultural College and Research Institute, Madurai to study the influence of drip fertigation levels and growth regulators on growth and yield of transplanted redgram. The experiment was laid out in a randomized block design with ten treatments and replicated thrice. The treatments include two levels of drip fertigation; 100% and 125% RDF (25:50:25 kg NPK/ha) with foliar spraying of 2% DAP, 1% triacontanol, 200 ppm mepiquat chloride and 100 ppm cycocel on 45 and 60 DAP. Among the treatments, drip fertigation of 125% RDF at weekly interval in equal splits from 15 to 90 DAP with foliar spraying of 2% DAP recorded higher plant height (174.9cm) and a number of branches per plant (35.8). It also proved its significance by recording the maximum grain yield (1539 kg/ha) and stalk yield (13,678 kg/ha) which was 37.4% higher than grain yield obtained under drip fertigation of 100% RDF to transplanted red gram.

Employee Commitment: Through Training Opportunities and Organization Compensation System

In today's dynamic environment, companies have been forced to operate at their highest rates. To ensure that this becomes a reality, every employee must be committed to organizational objectives and function as an effective member of the organization. However, reviewing the commitment of employees may be difficult, as it can be affected by different factors. The goal of this study was therefore to determine the factors that influence employee commitment in one of the established companies in Malaysia. To attain this, the study explored the relationship between training and development opportunities and organization compensation and benefit towards employee commitment. This study used a set of self-administered questionnaires to gather empirical data from 154 respondents employed in the company's subsidiaries. A Multiple Regression Analysis was conducted to investigate the effect of training and development opportunities and the organization’s compensation benefits on employee commitment. In the regression analysis, the R-Square value of 0.603 implies that the independent variables explain 60.3% of the variance in employee commitment. This study indicates that the organizations are encouraged to provide more valuable programs and increase hours for training and development opportunities, as well as to develop an effective compensation plan to enhance the commitment of the employees.
Multidrug-Resistant Microorganisms Associated with Urinary Tract Infections Following Orthopaedic Patients: A Laboratory-Based Analysis of 5239 Patients

Background: The risk of healthcare associated infections (HAI) in surgical wards remains closely related to the type of surgery and procedures performed on patients. They also condition the risk of various, apart from the most common, surgical site infections, forms of clinical infections, especially urinary tract infections (UTIs). Their occurrence in orthopedic patients is most often – in about 70%-80%, associated with the use of the bladder catheter in the perioperative period. The aim of this study was the epidemiological and microbiological analysis of UTIs following orthopedic patients, especially MDR in 2013-2015.Methods: The study was conducted in 38-bed Department of Orthopedic-Traumatic Surgery in Sosnowiec, Poland. 5 239 patients surgery included in the study, the urinary catheter utilization rate was 30.7 %. Laboratory based study using the UTI definition of the HAI-Net program, MDR was defined as resistant to at least one antibiotic from 2< antibiotics groups. The results were analyzed using the statistical package PQStat ver. 1.6. 0.428 using the chi-square test (chi ^ 2) or Fisher's exact test.Results The UTI incidence was 3.2% (168 cases), CA-UTI incidence density was 9.6/1 000 catheter-days. The highest risk of UTI was found in patients aged 75 years and older. Gram-negative flora prevailed among microorganisms: 76.1%. Predominantly isolated Enterobacterales were: Escherichia coli, Klebsiella pneumoniae. Isolated microorganisms were fully sensitive to carbapenems. Gram-negative bacilli showed the lowest sensitivity to extended substrate spectrum penicillins and fluoroquinolones: 37-64%, trimethoprim-sulfamethoxazole: 50%; MDR prevalence: 24.4%. Conclusions The presented data indicate that UTI incidence is a significant problem in studied population, as well as antimicrobialresistance, especially to quinolones and extended spectrum cephalosporins, as first-line therapy remains a major challenge. To reduce the problem of high UTI incidence and MDR prevalence, the priority should be the reduction of UTI risk – which exceeded the expected values.
THE EFFECT OF ADDITION SWIMMING CRAB SHELLS FLOUR (Portunus pelagicus) FOR PHYSICAL AND CHEMICAL QUALITY OF EDIBLE SPOON

Edible spoon product is a spoon-shaped cutlery that is fit to be eaten, this product was developed with the addition of alginate, however, it required high-cost raw material. Swimming crab shells were potential waste from underused swimming crabs which contained calcium carbonate (CaCO3) to strengthen the tissues, sources of calcium minerals, and formed edible spoon mixture. Swimming crab shells flour was the addition to the physicochemical quality of edible spoon and the best concentration for the product. This research utilized a completely randomized design (CRD) with different concentrations of swimming crab shell flour (0%, 8%, 10%, and 12%). The data were carried out with ANOVA and Tukey's HSD. The results showed that the addition of different swimming crab shell flour concentrations has a significant effect (P<5%) on the hardness parameters, melting time, hedonic properties, protein content, moisture content, carbohydrate content, and ash content except on fat content. The best concentration was 12% swimming crab shells flour with a hardness value of 10.32 ± 0.60 kgf, melting time of 15.02 ± 0.44 minutes, moisture content of 2.65 ± 0.24%, protein content of 8.31 ± 0.23%, carbohydrate content of 83.64 ± 0.29% , fat content of 1.42 ± 0.40% and ash content of 3.66 ± 0.06%. Edible spoon preferably has a hedonic value of 7.97
Not all gradable adjectives are vague – Experimental evidence from adults and children

This paper investigates whether absolute gradable adjectives such as clean show characteristics of vagueness, as do relative gradable adjectives such as big. We addressed this question by examining adults’ interpretation of the antonyms clean and dirty in a picture- selection task. Children between the ages of 3 and 5 were tested with the same task to see how early the interpretation pattern shown by the adults emerges in the course of acquisition. Our findings indicate that absolute gradable adjectives do not show characteristics of vagueness in either the adults or the children. Absolute gradable adjectives are interpreted as having a minimum or maximum standard of comparison, which is not context-sensitive, and they do not give rise to borderline cases.
Reforming Indigenous policing: Understanding the context for change

Protests over the policing of Black and Indigenous people and people of Colour that started after the death of George Floyd in May 2020 at the hands of the Minneapolis police set the stage for debates about the role of the Canadian police in ensuring public safety. These protests have resulted in calls for police reforms, including reallocating police funding to other social spending. The public’s attention has focused on urban policing, and there has been comparatively little focus on policing rural Indigenous communities. We address this gap in the literature, arguing that Indigenous policing is distinctively different than what happens in urban areas and the challenges posed in these places are unlike the ones municipal officers confront. We identify ten specific challenges that define the context for Indigenous policing that must be considered before reforms are undertaken. Implications for further research and policy development are identified, including founding a commission to oversee First Nations policing.
The effects of preoperative imaging stability studies on intraoperative correction, postoperative observation, and clinical efficacy of adult lumbar spondylolisthesis treatment

Background The aim of this study is to explore the use of preoperative imaging stability studies of adult lumbar spondylolisthesis and it's effects on intraoperative correction, postoperative observation, and clinical efficacy. Methods We retrospectively analyzed a total of 104 patients diagnosed with lumbar spondylolisthesis who underwent Posterior lumbar interbody fusion surgery between 2011 and 2014. The qualified patients were divided into two groups; group A (study/unstable group: 52 cases) and group B (control/stable group: 52 cases). Group A was further divided into group A1 (slip instability: 27 cases) and group A2 (angular instability: 25 cases). The preoperative lumbar sagittal plane translation distances and segmental angle of the preoperative lateral X-rays, hyperflexion X-rays, and hyperextension X-rays were measured and compared with their third-day postoperative lateral X-ray, and slip rate. The occurrences of intraoperative or postoperative complications, one-month postoperative follow-up data, including JOA, and VAS scores were access to evaluate the clinical efficacy of the treatment. Results Satisfactory postoperative radiographic correction was recorded in all groups. Better correction and correction was observed in group A1 patients and group B patients who used puller screws compared to those who used normal screws (P < 0.05). However, patients in group A2 who used normal pedicle screws had similar correction as those who used puller screws. The preoperative VAS scores showed that low back and lower extremity pain were higher in A1 and A2 groups compared to group B. However, they were lower one month postoperative. The preoperative JOA scores for the unstable groups (group A1 and A2) were lower than their stable counterpart but higher during the first month postoperative. Our analysis of postoperative complications also revealed no statistically significant difference between groups A1 and B, and groups A2, and B. Conclusions Preoperative imaging stability for adult lumbar spondylolisthesis does not affect intraoperative correction. The use of puller pedicle screws in patients with unstable or stable segmental slippage could achieve better correction and correction than with normal pedicle screws. The preoperative symptoms of patients with unstable segments were worse than their stable counterparts; however, their postoperative recovery was quicker in the first month postoperative.
Production and quality of watermelon grown under seaweed extract

The use of biofertilizers with macroalgae base has become a viable alternative to conventionally used synthetic fertilizers. Among the advantages of using these extracts is the increase in productivity and improvements in the agronomic performance of the crop. Its use is allowed in organic agriculture as it is a natural product. The objective of this research was to evaluate the influence of the seaweed extract, Ascophyllum nodosum (L.) to the productive development and quality of watermelon plants. A randomized block design with 6 treatments and 4 replications was applied. The treatments comprised of full or divided doses (total of 3.0 ml L-1) of seaweed extract (T1: producer standard; T2: (1.0 – 1.0 – 1.0 mL L-1) applied 2 - 16 - 30 days after transplanting (d.a.t.); T3: (1.5 - 1.5 ml L-1) 2 - 30 (d.a.t.); T4: (1.0 – 1.0 – 1.0 mL L-1) 16 - 30 - 44 (d.a.t.); T5: (1.5 - 1.5 mL L-1) 16 - 30 (d.a.t.) T6: (3.0 mL L-1) 2 (d.a.t.). 100 mL of the prepared solution was used for each experiment. The application of Acadian® improved the yield of water melon in the order of 12.69 to 27.76% and at different periods of the crop cycle.
