Metamizole or Novalgin® is a widely used well tolerated analgesic drug which is however compromised by agranulocytosis as adverse effect. Subsequent to nonenzymatic hydrolysis, the primary metabolic step is N-demethylation of 4-methylaminoantipyrine (4-MAA) to 4-aminoantipyrine (4-AA). The aim of the present study was to identify the human cytochrome P-450 enzyme (CYP) mediating this reaction. This study identified the relevant CYP using virus expressed isolated human CYP, human liver microsomes and rat liver microsomes with chemical inhibition studies. The substrate of 4-methylaminantipyrine was employed at six different concentrations (25, 50, 100, 400, 800 and 1200 µmol per l) with varying concentrations of selective inhibitors of CYP1A2 (furafylline, fluvoxamine), CYP3A4 (ketoconazole), CYP2A6 (coumarin), CYP2D6 (quinidine), CYP2C19 (omeprazole, fluvoxamine, tranylcypromine), CYP2C9 (sulphaphenazole) and CYP1A1 (alpha-naphthoflavone). 4-MAA and 4-AA were analyzed by HPLC and enzyme kinetic parameters (Km and Vmax) were determined by regression (Sigma plot 9.0). The N-demethylation of 4-MAA by microsomes prepared from baculovirus expressing human CYP was pronounced with CYP2C19. Intrinsic clearance of the most active enzymes were 0.092, 0.027 and 0.026 for the CYP enzymes 2C19, 2D6 and 1A2, respectively. Metabolism by human liver microsomes was strongly inhibited by fluvoxamin, omeprazole and tranylcypromine (IC50 of 0.07, 0.07 and 0.18, respectively) but with coumarin, sulphaphenazole, ketoconazole, moclobemid, quinidine alpha-naphthoflavone and furafylline were 0.79, 1.20, 1.36, 1.44, 3.46, 4.68 and 8.41, respectively. The enzyme CYP2C19 apparently has an important role in N-demethylation of 4-methylaminoantipyrine which should be further analyzed in clinical studies and which may also be interesting concerning the agranulocytosis.

Le 05 décembre 2012, les pratiques et expressions culturelles liées au balafon des communautés sénoufo du Mali, du Burkina Faso et de la Côte d’Ivoire ont été inscrites sur la Liste représentative du patrimoine culturel immatériel de l’humanité. Le tafal-djéguélé est une pratique et expression culturelle liée au balafon des Sénoufo de Côte d’Ivoire. Deux raisons principales fondent son usage : amener les laboureurs à la houe à se surpasser d’une part, et magnifier les valeurs des senambélé1 d’autre part, notamment celles en rapport avec le labour étant donné que le sénoufo est agriculteur par essence. Toutefois, en raison de certains changements sociaux, le tafal-djéguélése pratique de moins en moins. Cette situation prive le senanw d’aujourd’hui d’un cadre majeur d’enseignement et de diffusion de valeurs, et pose ainsi la question de leur transmission aux générations actuelles et futures. Cet article vise à démontrer comment la faible pratique du tafal-djéguélé empêche de nos jours la transmission de "valeurs- références" en pays sénoufo, mais aussi à proposer des pistes de solutions.

Saline and sodic (alkali) soils can significantly reduce the value and productivity of affected land. By estimation, slightly more than one-fourth of irrigated farmland in the United States is affected by soil salinity. Ions most commonly associated with soil salinity include the anions chloride (Cl–), sulfate (SO4=), carbonate (HCO3–), and sometimes nitrate (NO3–) and the cations sodium (Na+), calcium (Ca++), magnesium (Mg++), and sometimes potassium (K+). Crops differ in ability to tolerate salt accumulation in soils, but if levels are high enough (more than 16 mS/cm), only tolerant plants will survive. As salts accumulate in soil, the soil solution osmotic pressure increases. Reclamation of sodic soils is different; excess sodium must first be replaced by another cation and then leached. Sodic soils are treated by replacing the sodium with calcium from a soluble source.

Biological information processing networks rely on allosteric protein switches that dynamically interconvert biological signals. Construction of their artificial analogues is a central goal of synthetic biology and bioengineering. Receptor domain insertion is one of the leading methods for constructing chimeric protein switches. Here we present an in vitro expression-based platform for the analysis of chimeric protein libraries for which traditional cell survival or cytometric high throughput assays are not applicable. We utilise this platform to screen a focused library of chimeras between PQQ-glucose dehydrogenase and calmodulin. Using this approach, we identified 50 chimeras (approximately 23% of the library) that were activated by calmodulin-binding peptides. We analysed performance parameters of the active chimeras and demonstrated that their dynamic range and response times are anticorrelated, pointing to the existence of an inherent thermodynamic trade-off. We show that the structure of the ligand peptide affects both the response and activation kinetics of the biosensors suggesting that the structure of a ligand:receptor complex can influence the chimera's activation pathway. In order to understand the extent of structural changes in the reporter protein induced by the receptor domains, we have analysed one of the chimeric molecules by CD spectroscopy and hydrogen-deuterium exchange mass spectrometry. We concluded that subtle ligand-induced changes in the receptor domain propagated into the GDH domain and affected residues important for substrate and cofactor binding. Finally, we used one of the identified chimeras to construct a two-component rapamycin biosensor and demonstrated that core switch optimisation translated into improved biosensor performance.

Efforts to understand the causes of poverty, how poverty is perceived have become important in the fight to mitigate poverty. In Vietnam, studies on the attitudes of poverty in specific populations, such as Vietnamese students, are rare. Thus, this dataset reports the results collected from 180 social work students and non-social work students of Ho Chi Minh City Open University through attitudes toward poverty and poor people in Vietnam. The Attitude toward Poverty Short Form 21-item scale, developed by Yun & Weaver, was used for the data collection. The survey results showed that when looking for causes of poverty, social work students and non-social work students put the most emphasis on structural factors of poverty. However, social work students, compared with non-social work students, consider personal deficiency and stigma more important. In future, this dataset can serve as a reference source for comparative studies on student’ attitudes toward poverty and impoverished persons and for social work education.

Background and Objective: The COVID-19 pandemic affected medical care systems including stroke care, globally. In this study, we investigated the impact of the COVID-19 outbreak on stroke care in Hadramout, in terms of rate of admission, access to care, risk factors, clinical presentation, and outcome. Materials and Methods: A hospital-based cross-sectional study comparing all stroke patients admitted to Ibn-seena University Hospital (ISTH), Mukalla, Hadramout, during two periods, May 1–October 31, 2020, during the pandemic of COVID-19 (COVID-19 group), and from May 1 to October 31, 2019 (pre-COVID-19 group). Data collected from patients’ medical record files into a master sheet, and were processed by the Statistical Package for Social Sciences software. Results: There were 117 stroke patients admitted in COVID-19 pandemic in 2020, and 213 patients admitted in the same period in 2019. Stroke admission declined by 45.1% (Odds Ratio [OR]=0.30, 95% confidence interval [CI] [95% CI]: 0.22–0.42, p<0.0001) with no age and sex differences. Hypertension (HTN) and diabetes mellitus were more frequent in COVID-19 group than the pre-COVID-19 group (OR=1.74, 95% CI: 1.08–2.80, p=0.02) and (OR=1.81, 95% CI: 1.14–2, 88, p=0.01), respectively. No significant difference in other risk factors was found. Patients in COVID-19 group arrived the hospital more late than the patients in pre-COVID-19 group (OR=2.63, 95% CI: 1.64–4.21, p<0.0001). Dysphasia and altered consciousness including coma were more common in COVID-19 group compared with pre-COVID-19 group (OR=4.5, 95% CI: 2.18–9.08, p<0.0001) and (OR=3.2, 95% CI: 2.00–5.12, p<0.0001), respectively. Hospital stay was greatly reduced among COVID-19 group as compared with pre-COVID-19 group (02.9±0.31 days vs. 8.6±0.92 days, p<0.0001) Mortality rate was higher among COVID-19 group than the pre-COVID-19 group (41.9% vs. 27.2%, p=007). Conclusion: The number of stroke patients admitted during the COVID-19 pandemic decreased, they arrived late and spent shorter hospital stays while having higher rates of HTN, diabetes, and impaired consciousness with a high mortality rate.

Purpose: The study aims to explore all possible morphological features of calcium oxalate monohydrate and calcium oxalate dihydrate crystals and their habits in case of inhibition. Methods: The study was carried out on a glass slide to observe the growth and inhibition of calcium oxalate monohydrate (COM) crystals by using infusions (5-20%) of Macrotyloma uniflorum (Lam.) Verdc, Phaseolus lunatus Linn. and Phaseolus vulgaris Linn. The reagents of the double diffusion gel technique were used for this purpose. Results: Calcium oxalate crystals are divided into three types: calcium oxalate monohydrate, dihydrate, and trihydrate. These types are further divided into sub-types based on their morphology. In the case of calcium oxalate monohydrate (COM), these crystals are donuts, dumbbells, needles, platy, prismatic, rosette, round edges and X-shaped. Calcium oxalate dihydrate (COD) is the elongated large rods and tetragonal bipyramidal forms. In the present study, dendritic or arborescent (tree-like platy crystals) were observed for the first time as part of a COM growth. Long chain loose agglomerates and compact aggregated crystals are the typical pattern of calcium oxalate crystals. All tested infusions caused growth inhibition of calcium oxalate crystals. Smaller nucleation zones and defective shapes of the grown crystals are declared different growth inhibition patterns. Conclusion: This study gives extensive information about morphology, aggregation and growth inhibition of calcium oxalate crystals.

Background and Purpose: We aimed to investigate the effect of smoking on the risk of intracranial aneurysm (IA) rupture (IAR), specifically relationship between the number of cigarettes smoked per day (CPD) or smoking index and the risk of IAR. Materials and Methods: We performed a single-center case–control study of consecutive patients evaluated or treated for IA at our institution from June 2017 to July 2018. Cases were patients with a ruptured IA. Two age- and sex-matched controls with an unruptured IA were included per case. Conditional logistic regression models were used to assess the relationship between both the CPD and smoking index (CPD x years of smoking) and IAR. Results: The study population included 300 cases of IAR and 300 controls. The higher IAR risk was associated with cigarette smoking. Our subgroup analysis of smokers revealed a significant association between IAR risk and current smoking (OR, 2.8; 95% CI, 1.2–6.3; P = 0.012), current heavy smoking (CPD>20) (OR, 3.9; 95% CI, 1.4–11.0; P = 0.007), and a smoking index >800 (OR, 11.4; 95% CI, 2.3–24.5; P= 0.003). Conclusion: A dose–response relationship has been noted for intensity and duration of smoking consumption and increased risk of IAR. As smoking is modifiable, this finding is important to managing patients with IAs to quit or reduce smoking prior to life-threatening subarachnoid hemorrhage.

Scheduling is the need of every project. Without scheduling, projects don’t fulfill time constraints, go over spending plan. It is a process utilized by teams to organize and structure their resources so the tasks they need to complete are scheduled based on availability and capability. This process is more beneficial if it is required to allocate and assign task to the resources without allocating their schedules. This paper reviews different types of network scheduling techniques, which are used to schedule a task. These techniques are very effective and help us to preplan the whole scheduling process

The seeds for this work were planted many years ago when Linda Bean wastranscribing some of my lectures and encouraged me to write a book. Shepatiently labored through years of archived material until it was time for me tobegin writing. Her commitment and dedication to this project are deeplyappreciated.Once I began writing, Karen Entner assisted me by organizing materials,making content suggestions, and maintaining the manuscript. We workedtogether to edit version after version until the flow of words brought a sense ofpeace to the heart, mind, and soul. Her dedication and heartfelt work are muchappreciated and one of her lifelong dreams comes to fruition with the publicationof this book. “This above all: to thine own self be true, and it must follow,as the night the day, thou canst not then be false to any man.” —William ShakespeareShakespeare’s age-honored words, spoken by Polonius to his son Laertes in ActI of Hamlet, sound so clear and unambiguous. They tell us that to maintainhonest relations with others we must first be true to ourselves. Yet if Laerteswere to be totally honest with himself, he would realize that his father may aswell have told him to catch the wind. After all, to which “self” are we to be true?Is it the one that shows up when we’re in a bad mood, or the one that is presentwhen we feel humbled by our mistakes? Is it the one who speaks from the darkrecesses of the heart when we’re depressed or upset, or the one that appearsduring those fleeting moments when life seems so fanciful and light?From these questions we see that the concept of “self” may turn out to be abit more elusive than initially presumed. Perhaps if Laertes could have turned totraditional psychology, it would have shed some light on the subject. Freud(1927), the father of psychology, divided the psyche into three parts: the id, theego, and the superego. He saw the id as our primal, animal nature; the superegoas the judgment system that society has instilled within us; and the ego as ourrepresentative to the outside world that struggles to maintain a balance betweenthe other two powerful forces. But this certainly would not have helped youngLaertes. After all, to which of these conflicting forces are we to be true?Again we see that things are not always as simple as they seem. If we dare tolook past the surface of the term “self,” questions arise that many people wouldrather not ask: “Are the many aspects of my being all equally part of my ‘self,’or is there only one of me—and if so, which, where, how, and why?”In the following chapters, we will undertake a journey of exploration of“self.” But we will not do so in a traditional manner. We will neither call uponthe experts in psychology, nor upon the great philosophers. We will not argueand choose between time-honored religious views, or resort to statisticallysupported surveys of people’s opinions. We will, instead, turn to a single sourcethat has phenomenal direct knowledge on the subject. We will turn to one expertwho, for every moment of every day of their life, has been collecting the datanecessary to finally put this great inquiry to rest. And that expert is you.

The study examined public-private sectors’ collaboration in human resource management and curriculum development in the administration of public senior secondary schools in Rivers State. The study adopted the descriptive survey design. Two research questions and two hypotheses guided the study. The population of the study comprised 281 principals in the 281 public secondary schools in Rivers State. The proportionate stratified random sampling technique was used to draw up sample of 259 principals representing 92.2% of the population of the study (211 male principals and 70 female principals). An instrument titled: Public-Private Sectors’ Collaboration for School Administration Questionnaire (PPSCSAQ) designed in the modified 4-point Likert Scale with a reliability index of 0.87 was used for data collection. The face and content validities were ensured. Mean and standard deviation were used in answering the research question while z-test was used in testing the hypotheses at 0.05 level of significance. The finding of the study showed that to a high extent public-private sectors collaborate in human resource management and curriculum development in the administration of public senior secondary schools in Rivers State. It was recommended among others that the government should provide enabling environment and formulate favourable policies to sustain public-private sectors’ collaboration as it ensures effective human resource management in the state.

A simple, rapid, sensitive reversed-phase high-performance liquid chromatography method was developed and validated for simultaneous measurement of albendazole and praziquantel with an internal standard, simvastatin, at single wavelength of 225 nm. Chromatographic separation was performed on an Enable C18 column (250 mm × 4.6 mm, 5 μm: Spinco Biotech Pvt Ltd) and a mobile phase consisting of acetonitrile:water (60:40, v/v) with 10% orthophosphoric acid to adjust the pH to 3.2, at a flow rate of 1.0 ml/min. The calibration curve was linear (r2 ≥ 0.999) over the concentration range 0.05–8.0 μg/ml. The concentrations of simvastatin was 1.0 μg/ml. The limit of quantification was 0.05 μg/ml for both albendazole and praziquantel. No interference was found by the excipients in the synthetic mixture. The proposed methods were validated as per International Conference on Harmonisation guidelines for linearity, accuracy, precision and robustness for estimation of albendazole and praziquantel in bulk and in a synthetic mixture, and the results were found to be satisfactory.

Monosodium urate monohydrate crystals are deposited in peripheral joints, causing gout and eliciting an intense localized inflammatory attack. In contrast, collecting ducts and medullary interstitium is a urinary calculus, which causes dysuria, nausea and hematuria. The purpose of the present study is to observe possible growth patterns of monosodium urate monohydrate crystals. The crystals were grown in test tubes using a single diffusion gel technique and were observed on the 7th,14th, 21st, 28th, and 40th days. Needle and spherulite-type crystals were observed on the 14th day, while arboresque, crystal sheaves, densely branched, dumbbell, mushroom-type spherulites, plumose and hexagonal prismatic crystals were observed for the first time. After the 40th day, complete spherulites were observed with their aggregates. The crystals were characterized by Scanning Electron Microscopy, Energy-Dispersive X-ray and Fourier Transform infrared spectroscopies. The pattern of MSUM will help determine the role of different natural products in the modulation, inhibition or promotion of these crystals by affecting the shape, size, transparency, approximate number and total mass of growing crystals. In case of inhibition or modulation, it will help evaluate prophylactic management. In contrast, the promotion of the crystal will give an idea about the risk factors of gout and kidney stones.

Alzheimer Disease is a chronic neurological brain disease. Early diagnosis of Alzheimer illness may the prevent the occurrence of memory cellular injury. Neuropsychological tests are commonly used to diagnose Alzheimer’s disease. The above technique, has a limited specificity and sensitivity. This article suggests solutions to this issue an early diagnosis model of Alzheimer’s disease based on a hybrid meta-heuristic with a multi-feed-forward neural network. The proposed Alzheimer’s disease detection model includes four major phases: pre-processing, feature extraction, feature selection and classification (disease detection). Initially, the collected raw data is pre-processed using the SPMN12 package of MATLAB. Then, from the pre-processed data, the statistical features (mean, median and standard deviation) and DWT are extracted. Then, from the extracted features, the optimal features are selected using the new Hybrid Sine cosine firefly (HSCAFA). This HSCAFA is a conceptual improvement of standard since cosine optimization and firefly optimization algorithm, respectively. Finally, the disease detection is accomplished via the new regression- based multi-faith neighbors’ network (MFNN). The final detected outcome is acquired from regression-based MFNN. The proposed methodology is performed on the PYTHON platform and the performances are evaluated by the matrices such as precision, recall, and accuracy.

ROS (Reactive Oxygen Species) production via oxidative stress leads to selective neuronal degeneration and finally results in neurodegenerative diseases. PD (Parkinson’s disease) is one of the second most common neurodegenerative disease caused by overproduction of ROS due to the activity of xanthine oxidase. XO activity inhibitors may prove to be promising antiparkinson agents. Present investigation describes the synthesis and characterization of fluoro substituted pyrazolyl pyrazoline derivatives using spectrometer and 1HNMR spectra. Molecular docking studies of NAP1-NAP5 derivatives were performed in silico using molecular docking software. The resulting dock score in terms of D score has been compared with the standard XO inhibitor i.e. Allopurinol and Oxypurinol. The in silico approach used to study the Drug and Enzyme interaction using docking mechanism. Results indicated that the NAP derivatives accounted for better region specificity towards XO. It shows the strong binding interaction of ligand and receptor calculated on the basis of D score; hence the D score shows highest affinity. Overall score tabulation for D score as 2NAP1: -101.78; 2NAP2: -118.32; 2NAP3: -99.921; 2NAP4: -105.22; 2NAP5: -101.56; accordingly with the comparison of standard ligand molecule i.e. Allopurinol: -37.016 and Oxypurinol: -37.233.

Ecbalium elaterium has a very violent effect on the body and has little use in modern herbalism. Little is known about the acute and chronic toxicities of ecbalium elaterium in human. This study aims to determine the acute toxicity (LD50) of fruit extract and another aerial part extract of the ecballium elaterium in experimental animals. Thus, male albino mice were divided into different groups each group consists of six mice receiving 40, 46, 52, 61, and 69 mg/kg of fruit extract of ecballium elaterium, respectively. Other groups were given 1000, 1412, 1995, 2818, and 3981 mg/kg of the areal part of ecballium elaterium extract, respectively. The LD50 in both treatments was determined by using the Spearman-Karber method. The LD50 of the fruit and aerial parts of ecballium were 55 mg/kg and 2112.5 mg/kg, respectively. The present findings showed significant weight loss after one month of treatment with 1400 mg/kg and 40 mg/Kg of fruit and aerial part extracts, respectively. The results indicated that the fruit extract is highly toxic as compared to the extract of the aerial parts.
