Correlation of Surface Wettability and Corrosion Rate for Benzotriazole‐Treated Copper

Field: Chemistry (Physical Sciences)

The wetting characteristics of copper surfaces, with and without an exposure to benzotriazole and benzotriazole derivatives, have been investigated by dynamic contact angle measurements. The results were compared to corrosion rates measured on the same samples by electrochemical techniques. The experiments show that the inhibitor's effectiveness for corrosion reduction is not reflected well by the advancing contact angles of water. However, a good correlation is observed with the parameters obtained on a previously wetted surface, such as receding contact angles and the work of surface rewetting. These parameters were obtained through repeated dipping experiments. The details of the wetting process are evaluated quantitatively as an excess work of adhesion and can be used as an alternate measure of the expected corrosion resistance for differently treated surfaces.
Photodynamic antimicrobial chemotherapy (PACT) using phenothiazines derivatives associated with the red-orange LED againststaphylococcus aureus

Field: Pharmacology, Toxicology and Pharmaceutics (Life Sciences)

The objective of this study was to contribute to PDT development by researching alternative light sources using redorange LED light at doses of 2.4 e 4.8 J/cm2 to evaluate the bactericidal effect of photodynamic antimicrobial chemotherapy (PACT) using phenothiazinium dye (Toluidine blue O and methylene blue) at a low concentration of 1μg/mL on strain of Staphylococcus aureus (ATCC 23529) in vitro. For this research, tests were performed in triplicate and the samples were distributed into six test groups: (L-P-) Negative control (L1+ P-) and (L2+ P-) bacterial suspensions were irradiated with laser energy 2.4 and 4.8 J/cm2 respectively in the absence of photosensitizer; (L1 + P+) and (L2 + P+) bacterial suspensions were irradiated with laser in the presence of 1μg/ml of photosensitizer and finally (L-P+) bacterial suspensions only in the presence of phenothiazinium dye. Therefore, were analyzed the potential bactericidal PACT by counting of colony-forming units and analyzed statistically (ANOVA, Tukey test, p<0.05). The results demonstrated that comparing the LED group (L2 + P-) with negative control group, LED group (L1+ P-) and photosensitizer group there was a statistically significant (p<0.0001, p<0.01 and p<0.001, respectively) that the group treated only with LED (energy density of 4.8J/cm2) increased the average of CFU counts. The negative control group when compared to the groups submitted to PDT only showed a statistically significant reduction (p<0.01) relative to the group (L2+P+) that showed a decrease in the number of CFU. There was no statistically significant difference between the groups submitted to PDT (L1+P+ and L2+P+). Although the results of this study have shown a reduction in average number of colony forming units by the appropriate LED-dye treatment combination, it needs further investigation.
The Effect of Hygiene and Motivator Factors on Employee Retention. A Case Study in Padiberas Nasional Berhad (BERNAS) Kelantan

Field: Business, Management and Accounting (Social Sciences)

The objective of this study was to examine the relationship between for factors which are work environment,compensation, training/development and supervisor support and employee retention in Padi Beras Nasional Berhad (BERNAS) in Kelantan. The research done by mean of survey, a questionnaire was distributed to 60 respondents. Data was analyzed by “Statistical Package for Social Science”(SPSS Window) Version 16.0. Correlation analysis was used to test the inter correlation between the variables. Correlation result shows that two variables i.e work environment and supervisor support were correlated and two variables i.e compensation and training/development were not correlated with employee retention in the organization. However,in the multiple regression analysis, it was found that work environment, compensation, training/development and supervisor support were related to employee retention. Work environment has the higher effect on employee retention. This means that work environment is the dominant factor influencing the employee retention of the BERNAS Kelantan workers. These findings show that the related factors should be given attention to retain employees in the organization. Some recommendation have been offered for the organization and future research.

Optimisation of extraction of valuable metals from waste LED via response surface method

Field: Chemical Engineering (Physical Sciences)

The valuable metals were separated and extracted from waste light-emitting diodes (LEDs) by pyrolysis and leaching process. About 98.16% Ga and 99.54% Y were recycled from the LEDs after the pyrolysis by sieving process in advance. The effects of various leaching conditions on the extraction of Fe, Cu and Ag were investigated by single factor experiments and response surface method. About 90.15% Fe was selectively extracted from the waste LEDs by H2SO4 leaching without oxidant, and 99.55% Cu and 99.36% Ag were recovered from the iron leaching residue by acid leaching with the addition of HNO3. The XRD and SEM−EDS analyses confirmed that the iron and copper were effectively extracted from the waste LEDs by the developed process.
Maternal Near-Miss Obstetric Events and Maternal Mortality

Field: Medicine (Health Sciences)

Aim: To know about the prevalence, characteristic and nature of near miss events and to relate the nature of near miss events with that of maternal mortality. Study design: Descriptive cross sectional study Place and duration of study: Department of Obstetrics & Gynecology Unit IV, LUMHS Jamshoro from 1st January 2020 to 31st December 2020 Methodology: Pregnancy outcomes segregated into maternal death, near-miss event, or live birth categories. Age, level of education, religion, and residence were socio demographic variables. Obstetrics characteristics and nature of maternal near-miss events also studied. Result: The prevalence of maternal near-miss event was 5.6%, and the maternal near-miss events were seen more in multigravida, pregnant women with the lack of antenatal care in referral cases. Live birth as fetal outcome was 75%. The maternal death to near-miss ratio in this study was 1:5. 44 (42.3%) postpartum haemorrhage and 28 (26.9%), hypertensive disorders cases were leading cause of maternal near-miss events. Conclusion: Every fifth women who survived life-threatening complications, one died. Maternal near-miss should be adopted as an indicator for evaluating maternal health services. Keywords: Maternal near-miss (MNM), Maternal mortality, Life-threatening complication
Phenotypic and genetic diversities are not correlated in strains of the cyanobacterium Microcystis aeruginosa isolated in SW Spain. Las diversidades fenotípica y genética de cepas de la cianobacteria Microcystis aeruginosa aisladas en el SW de España no están correlacionadas

Field: Agricultural and Biological Sciences (Life Sciences)

English. The cyanobacterium Microcystis aeruginosa (Kützing) Kützing is notorious for forming extensive and toxic blooms but the genetic structure of natural populations, and in particular during blooms, remains to be explored. In order to add more knowledge about the genetic structure of M. aeruginosa, we compared phenotypic and genetic variabilities in seventeen strains of M. aeruginosa isolated from three adjacent water bodies in SW Spain (the consecutive reservoirs La Minilla and El Gergal, and small pools in Doñana National Park). For this purpose, a phenetic tree, based on six phenotypic traits (including morphology of cells, photosynthetic and respiratory performance, and toxin production) was compared with a phylogenetic tree built by using the 16S-23S rDNA Internal Transcribed Spacer sequence. Whereas the strains isolated from La Minilla showed a relatively homogeneous phenotype, the phenotypic traits of the remaining strains did not discriminate between the other two water bodies. On the other hand, only a strain isolated in Doñana National Park showed a slightly different ITS sequence, but the sequences from the remaining strains were similar. Possible explanations for this discrepancy between phenotypic and genetic diversities are discussed.Español. La cianobacteria Microcystis aeruginosa (Kützing) Kützing puede dar lugar a extensas floraciones tóxicas pero la estructura genética de las poblaciones naturales, y en particular durante las floraciones, ha sido escasamente estudiada. Con el objeto de profundizar en la estructura genética de M. aeruginosa, se han comparado las variabilidades fenotípica y genética de diecisiete cepas aisladas de tres cuerpos de agua adyacentes en el SW de España (los embalses consecutivos de La Minilla y El Gergal, y charcas en el Parque Nacional de Doñana). Para este fin, un árbol de similitud fenética basado en seis caracteres fenotípicos (que incluyen la morfología de las células, el rendimiento fotosintético y respiratorio y la producción de toxina) se comparó con un árbol filogenético construido mediante el uso de la secuencia de ITS 16S - 23S del ADNr. Las cepas aisladas en La Minilla mostraron un fenotipo relativamente homogéneo pero no se detectó un patrón de fenotipos que discriminase los otros dos cuerpos de agua. Por otro lado, sólo una cepa aislada en el Parque Nacional de Doñana mostró una secuencia ITS diferente, pero las secuencias de las cepas restantes fueron idénticas. Se discuten las posibles explicaciones para esta discrepancia entre la diversidad fenotípica y genética en M. aeruginosa.
[Arsenic trioxide induced leukemic cell apoptosis relative to NF-kappaB activation].

Field: Biochemistry, Genetics and Molecular Biology (Life Sciences)

To investigate the relationship of As(2)O(3)-induced leukemic cell apoptosis with NF-kappaB activation and expression of VEGF, MMP9, apoptosis of K562-n cells induced by As(2)O(3) was analyzed by Annexin V, the dynamic changes of NF-kappaB, MMP9 and VEGF expressions were detected by immunohistochemistry. The results showed that activity of NF-kappaB could be increased, accompanied by higher level of expression of MMP9 and VEGF when apoptosis of K562-n cells was induced by As(2)O(3). Dexamethasome not only increased significantly the apoptotic rate, but also suppressed the activation of NF-kappaB of K562-n cells induced by As(2)O(3). Furthermore, there was a positive correlation between the expression of MMP9, VEGF and the activity of NF-kappaB. It is concluded that As(2)O(3) can induce apoptosis, in the meanwhile, activate NF-kappaB and up-regulate expression of MMP9 and VEGF in K562-n cell line. The mechanism of apoptosis of K562-n cells enhanced by dexamethasome may be related to suppression of the activation of NF-kappaB and expression of MMP9 and VEGF.
The Party Leadership Model: An early forecast of the 2015 British General Election

Field: Social Sciences (Social Sciences)

British political parties select their leaders to win elections. The winning margin of the party leader among the selectorate reflects how likely they think she is to win the General Election. The present research compares the winning margins of party leaders in their party leadership elections and uses the results of this comparison to predict that the party leader with the larger winning margin will become the next Prime Minister. I term this process “the Party Leadership Model”. The model correctly forecasts 8 out of 10 past elections, while making these forecasts 4 years in advance on average. According to a Bayesian analysis, there is a 95 per cent probability that having the larger winning margin in party leadership elections increases the chances of winning the General Election. Because David Cameron performed better among Conservative MPs in 2005 than Ed Miliband did among Labour MPs in 2010, the model predicts Cameron to become Prime Minister again in 2015. The Bayesian calculation puts his chances of re-election at 75 per cent.
Melatonin Enhances Anti-tumoral Effects of Menadione on Colon Cancer Cells

Field: Pharmacology, Toxicology and Pharmaceutics (Life Sciences)

Background: Colon cancer is one of the most important causes of death in the entire world. New pharmacological strategies are always needed, especially in resistant variants of this pathology. We have previously reported that drugs such as menadione (MEN), D, L-buthionine-S,R-sulfoximine or calcitriol, used in combination, enhanced cell sensibility of breast and colon tumour models, due to their ability to modify the oxidative status of the cells. Melatonin (MEL), a hormone regulating circadian rhythms, has anti-oxidant and anti-apoptotic properties at low concentrations, while at high doses, it has been shown to inhibit cancer cell growth. Objective: The objective of this study is to determine the antitumoral action of the combination MEN and MEL on colon cancer cells. Methods: Caco-2 cells were employed to evaluate the effects of both compounds, used alone or combined, on cellular growth/morphology, oxidative and nitrosative stress, and cell migration. Results: MEN plus MEL dramatically reduced cell proliferation in a time and dose-dependent manner. The antiproliferative effects began at 48 h. At the same time, the combination modified the content of superoxide anion, induced the formation of reactive nitrogen species and enhanced catalase activity. Cell migration process was delayed. Also, changes in nuclear morphology consistent with cell death were observed. Conclusion: The enhanced effect of simultaneous use of MEN and MEL on Caco-2 cells suggests that this combined action may have therapeutic potential as an adjuvant on intestinal cancer acting in different oncogenic pathways.
The vasoactive potential of kisspeptin-10 in the peripheral vasculature. PLoS ONE 6: e14671

Field: Pharmacology, Toxicology and Pharmaceutics (Life Sciences)

Splice products of the Kiss1 protein (kisspeptins) have been shown to be involved in a diverse range of functions, including puberty, metastasis and vasoconstriction in large human arteries. Circulating Kisspeptin-10 (Kp-10) plasma levels are low in normal individuals but are elevated during various disease states as well as pregnancy. Here, we investigated the potential of Kp-10, the shortest biologically active kisspeptin, to influence microvascular effects, concentrating on the cutaneous vasculature. Kp-10 caused a dose-dependent increase in oedema formation (0.3–10nmol/injection site), assessed by Evans Blue albumin dye extravasation, in the dorsal skin of CD1 mice. Oedema formation was shown to be inhibited by the histamine H1 receptor antagonist mepyramine. The response was characterised by a ring of pallor at the injection site in keeping with vasoconstrictor activity. Therefore, changes in dorsal skin blood flow were assessed by clearance of intradermally injected 99m technetium. Kp-10 was found to significantly reduce clearance, in keeping with decreased blood flow and providing further evidence for vasoconstrictor activity. The decreased clearance was partially inhibited by cotreatment with the cyclo-oxygenase inhibitor indomethacin. Finally evidence for the kisspeptin receptor gene (Kiss1R), but not the kisspeptin peptide gene (Kiss1), mRNA expression was observed in heart, aorta and kidney samples from normal and angiotensin II induced hypertensive mice, with similar mRNA levels observed in each. We have evidence for two peripheral vasoactive roles for kisspeptin-10. Firstly, plasma extravasation indicative of ability to induce oedema formation and
Cervical Kinematics of Fast Neck Motion across Age

Field: Medicine (Health Sciences)

Purpose: To evaluate the velocity, smoothness, and symmetry of fast cervical motion in asymptomatic individuals of four age groups, and to investigate the relationship between age and these measures. Methods: Cross-sectional study with fifty-eight asymptomatic volunteers (28 F, 30 M), aged 18-80 (mean age=44.14 ± 17.35) were assessed using a customized Virtual Reality (VR) system. VR head-mounted display stimulated fast neck movements in response to virtual targets appearing randomly. Outcome measures were neck motion velocity, smoothness, and symmetry of velocity profile. Main findings: The eldest group differed from younger age groups in peak and mean velocity of neck motion. Smoothness demonstrated age-group difference only between the youngest and oldest groups. Linear regression analysis showed significant negative correlations in mean and peak velocity, and in smoothness with age, excluding smoothness in right rotation. No age-group differences and no significant correlations were found for time-to-peakvelocity in all directions of neck movement (p>0.05). Conclusion: This study showed that age influenced the velocity in which asymptomatic individuals could move their neck, specifically in elders over 60 years of age. Clinically, this may suggest that when elders with neck pain present with slower cervical motion, it is probably partly due to aging and thus should be taken into account in the management and expected level of performance.
Development and validation of an infrared-artificial intelligence software for breast cancer detection

Field: Medicine (Health Sciences)

Aim: In countries where access to mammography equipment and skilled personnel is limited, most breast cancer (BC) cases are detected in locally advanced stages. Infrared breast thermography is recognized as an adjunctive technique for the detection of BC due to its advantages such as safety (by not emitting ionizing radiation nor applying any stress to the breast), portability, and low cost. Improved by advanced computational analytics techniques, infrared thermography could be a valuable complementary screening technique to detect BC at early stages. In this work, an infrared-artificial intelligence (AI) software was developed and evaluated to help physicians to identify potential BC cases. Methods: Several AI algorithms were developed and evaluated, which were learned from a proprietary database of 2,700 patients, with BC cases that were confirmed through mammography, ultrasound, and biopsy. Following by evaluation of the algorithms, the best AI algorithm (infrared-AI software) was submitted to a clinic validation process in which its ability to detect BC was compared to mammography evaluations in a double-blind test. Results: The infrared-AI software demonstrated efficiency values of 94.87% sensitivity, 72.26% specificity, 30.08% positive predictive value (PPV), and 99.12% negative predictive value (NPV), whereas the reference mammography evaluation reached 100% sensitivity, 97.10% specificity, 81.25% PPV, and 100% NPV. Conclusions: The infrared-AI software here developed shows high BC sensitivity (94.87%) and high NPV (99.12%). Therefore, it is proposed as a complementary screening tool for BC.
Antibody detection and sequence analysis of sporadic HEV in Xiamen region

Field: Medicine (Health Sciences)

Hepatitis E virus (HEV) is transmitted through a fecal-oral route[1]. HEV induces acute hepatitis and is responsible for a significant portion of the fulminant hepatitis in epidemic and sporadic cases, especially in the mixed infection patients and women in their third trimester of pregnancy[1]. It has been reported that HEV infection is more prevalent in underdeveloped and develo ping countries in Asia, Africa, and Central America, but is rare in developed countries[1]. In China, a large outbreak occurred between 1986 and 1988 in Xinjiang, and sporadic spread was often found in other regions.

HEV is a non-enveloped virus, approximately 27 nm-34 nm in diameter and has a positive-sense, single-stranded RNA genome of approximately 7.2 kb. The viral genome consists of three discontinuous open reading frames (ORFs). Since the molecular cloning and sequencing of HEV were described[2], several genomic analyses of HEV strains obtained from different geographic areas have been reported[3]. The existing variations on the gene structure of HEV strains from some regions of China was reported by us[4]. In this study, after the collection of the serum samples of patients with acute hepatitis in Xiamen, anti-HEV antibody and HEV RNA in serum were detected, further HEV RNA was cloned and sequenced. The results are described and discussed.

Abstract: BHIM app helps to make speedy, relaxed and simple payment transactions using UPI. It offers some important features such as sending money, requesting money, scan and pay, transactions history, switch between multiple banks accounts, availability in almost all regional languages and much more. Its usage has been increasing day by day especially after the COVID 19 Pandemic broke out in India. Hence, this study has been carried out with the objective to study usage of BHIM during COVID 19 and its impact on Number of Banks Live on BHIM, Number of BHIM transactions and Value of BHIM transactions before and during COVID 19 pandemic. The period of the study covers 50-months, i.e., 25 months after COVID -19 pandemic broke out covering the three waves of the pandemic and 25 months before the pandemic. The study found that with the increase in banks live on BHIM has increased during the study period; there has been increase in Volume of BHIM transactions. With the increase in Volume of BHIM transaction, there has been increase in Value of BHIM transactions. As the means of number of banks live on BHIM App, Volume of BHIM transactions and Value of BHIM transactions have increased significantly during the three waves of the pandemic in India, it can be concluded that BHIM App has been becoming popular in making digital payments in India as compared to other Apps.
