The present study was aimed to assess the inhibition effects of organophosphate pesticides, malathionR, dichlorvosR; pyrethroid pesticides, deltamethrinR, λ-cyhalothrinR on antioxidantenzymes and reactivation ability of pralidoxime against pesticide inhibited-antioxidant enzymes. Oximes were reported by reactivation ability against organophosphate inhibited- acetylcholinesterase and we focused to investigate the reactivation effect of pralidoxime against organophosphate inhibited–antioxidant enzymes. IC50 values were determined by means of activity percentage diagrams. The concentrations of deltamethrinR, malathionR,dichlorvosR, λ-cyhalothrinR that inhibited 50% of catalase were 5.2 μM, 158 μM, 133 μM,320 μM, respectively, inhibited 50% of superoxide dismutase were 62 μM, 240 μM, 328 μM, 2320 μM, respectively and inhibited 50% of glutathione peroxidase were 0.7 μM, 1198 μM, 1638 μM, 98 μM, respectively. All pesticide doses showed inhibition effect on antioxidant enzymes. DeltamethrinR was found to be a more potent inhibitor for the antioxidant enzymesfollowed by the rest of pesticides used in this study. Reactivation effect of pralidoxime was determined for organophosphate inhibited-enzymes. Reactivation results showed that only catalase is reactivated by pralidoxime against dichlorvosR and malathionR. Under the exposureof 50-800 μM malathionR concentrations, catalase activity % was calculated as 72-11%,respectively. After inhibited catalase by malathionR incubated with 1 mM and 10 mMpralidoxime, catalase activity % was calculated as 92-31% and 98-39%, respectively. Under the exposure of 100-1500 μM dichlorvosR concentrations, catalase activity % was calculatedas 50-6%, respectively. After inhibited catalase by dichlorvosR incubated with 1 mM and 10mM pralidoxime, catalase activity % was calculated as 95-30% and 93-28%, respectively. When the results are examined, it is seen that increasing the pralidoxime concentration does not significantly affect the reactivation percentage of the catalase enzyme.

Radioactivity in egg was investigated. The targeted radionuclides were the long-lived gamma emitters 228Ra, 226Ra, and 40K. Measurements were carried out using a high purity germanium detector. The calculated annual effective dose due to egg consumption was 79 μSv yr-1, which forms 1/4 of the 290 μSv yr-1 world average ingestion exposure from natural sources. Hence, no radiological hazards exist from egg consumption due to the presence of the investigated radionuclides.

Proteases have gained more commercial value to date due to multiple applications in different industrial sectors. Current research was aimed to use the cheaper agricultural waste for optimal protease production. Maximum level of protease production was achieved at 37 °C, incubation period of 24 h, pH 9.0, inoculum size 3%, 1.5 g sucrose as a carbon source and 30% moisture content by using solid-state fermentation. Among the various inorganic and organic nitrogen sources, ammonium nitrate and yeast extract tremendously increased the production of protease. Among metal ions and surfactants tested, Ca2+ and Tween 40 showed the optimal protease production. The purification of protease was carried out by ammonium salt precipitation followed by sephadex G-100 gel filtration chromatography. The purification resulted in 1.3 fold of purified protease with a specific activity of 51.5 and a total yield of 37.5 %. Molecular weight of purified protease was predicted upon SDS-PAGE with a single band of ~36 kDa. The protease was quite stable over a temperature range of 35-45 °C and pH 7-9 with maximal activity at 40 °C and pH 9. The kinetic parameters Vmax (maximum rate) and Km (Michaelis-Menten constant) were calculated as 0.307 U/g and 11.2 mg/mL, respectively. The alkaline protease significantly de-hair the goat skin and successfully removed the animal blood stain from cotton cloth.

The depth and pose information are the basic issues in the ﬁeld of robotics, autonomous driving, and virtual reality, and are also the focus and difﬁcult issues of computer vision research. The supervised monocular depth and pose estimation learning are not feasible in environments where labeled data is not abundant. Self-supervised monocular video methods can learn effectively only by applying photometric constraints without expensive ground true depth label constraints, which results in an inefﬁcient training process and suboptimal estimation accuracy. To solve these problems, a monocular weakly supervised depth and pose estimation method based on multi-information fusion is proposed in this paper. First, we design a high-precision stereo matching method to generate a depth and pose data as the "Ground Truth" labels to solve the problem that the ground truth labels are difﬁcult to obtain. Then, we construct a multi-information fusion network model based on the "Ground truth" labels, video sequence, and IMU information to improve the estimation accuracy. Finally, we design the loss function of supervised cues based on "Ground Truth" labels cues and self-supervised cues to optimize our model. In the testing phase, the network model can separately output high-precision depth and pose data from a monocular video sequence. The resulting model outperforms mainstream monocular depth and poses estimation methods as well as the partial stereo matching method in the challenging KITTI dataset by only using a small number of real training data(200 pairs).

In recent time, the Bayesian approach to randomized response technique has been used for estimating the population proportion especially of respondents possessing sensitive attributes such as induced abortion, tax evasion and shoplifting. This is done by combining suitable prior information about an unknown parameter of the population with the sample information for the estimation of the unknown parameter. In this study, possibility of using a transmuted Kumaraswamy prior is raised, yielding a new Bayes estimator for estimating population proportion of sensitive attribute for Warner’s randomized response technique. Consequently, the proposed Bayes estimator with transmuted Kumaraswamy prior is compared with existing Bayes estimators developed with a simple beta and Kumaraswamy priors in terms of their mean square error. The proposed estimator competes well with the existing estimators for some values of population proportion. The performances of Bayes estimators were also compared using some benchmark data.

Photocatalysis is a process of accelerating reactions that are assisted by energy from light irradiation. Titanium dioxide (TiO2) is one of the most widely developed photocatalysis materials, and is used because of its high catalytic activity, stability and very affordable. The most commonly used precursors of TiO2 are titanium butoxide (TBOT) and titanium tetraisopropoxide (TTIP). These variations in precursor can lead to phase difference in the formation of TiO2 crystals, which further improves its nature in the activity of photocatalysis. In this study, the sol-gel method was used to synthesize titanium dioxide nanoparticles from variations of TBOT and TTIP. Furthermore, the structure, crystallite size and band gap of TiO2 were determined by X-ray diffraction (XRD) and UV-vis reflectance spectroscopy (DRS). Subsequently, TiO2 photocatalytic activity was evaluated in phenol photodegradation as a contaminant model with UV irradiation. The results showed the structure synthesized from TBOT had a higher amount of anatase, higher crystallinity, smaller crystallite size, larger band gap, and better photocatalytic activity than those from TTIP. Furthermore, it was shown that TiO2 from TBOT had an efficiency of 147% greater than TiO2 P25 Degussa, while TiO2 from TTIP had 66% efficiency compared to TiO2 P25.

Obesity is among the most common complex diseases with a high rate of morbidity and mortality globally and locally in Kuwait. Tumor Necrosis Factor-α(TNF-α) is a pro-inflammatory cytokine that is primarily secreted by monocytes/macrophage. Increased expression of TNF-α has been observed in the adipodse tissue of obese subjects that could disrupt lipid metabolism and lead to and lead to sustained obese state and obesity-related diseases. The human TNF-α promoter exhibits a high number of genetic variants, mainly single nucleotide polymorphisms (SNPs) that have been shown to influence the level of transcription in association with diseases. The human TNF-α genetic variants have never been fully reported in Arabs, therefore, we aimed to identify these variants by sequencing the TNF-α promoter, 5' UTR, and exon 1 in 290 Kuwaiti Arabs. As a result, we identified 14 genetic variants, including one novel SNP. Two promoter SNPs; rs1800750 (- 376G>A) and rs361525 (-238G>A) were found to be in strong linkage disequilibrium (r2 = 0.73) and (D′ = 1, LOD = 32). To investigate the association of rs361525 (-238G>A) with obesity, we genotyped an additional 573 samples of the general Kuwaiti population by Real-time PCR (total n=863). Linear and logistic regression analysis have not shown any significant association in carriers of the A allele of rs361525 with continuous and categorical BMI, respectively. This is the first study in the Middle East and Kuwait that has sequenced and identified the common, rare and novel genetic variants of TNF-α promoter, 5'UTR and exon 1 in Arabs.

Leptadenia pyrotechnica (Forssk.) Decne. (LP) is used in folk medicine for the treatment of different ailments. No published studies on the affects of ground and aqueous LP extract in laboratory animals exist. Thus, this study is the first to investigate the difference between using ground or aqueous extract of LP on body weight parameters and consumptions of feed and water in young adult Wistar albino rats. Four groups (one rat of either sex for each group) were administered 25%, 50% and 75% ground LP mixed with the regular feed for 7 days, while the control rats were given the regular diet. Five groups (two rats of either sex for each group) were orally gavaged with 3, 9, 15 and 20 g LP extract/kg body weight, while the control group was gavaged with water, daily for 14 days. Findings were compared with the control groups. The mean body weight loss and feed inefficiency ratio s for the ground LP groups were higher, leading to lower feed and water intakes. Rats that consumed 15 and 20 g LP extract/kg had higher mean body weight loss and feed inefficiency ratio and lower water and feed intakes for the first but not for the second week. Therefore, both forms of LP affect weights and consumptions of water and feed during the first week. Thus, while using LP for any medicinal or therapeutic uses in humans, any affects on weight or feed and water consumptions may last only for a week.

The paper estimates the global solar radiation in Dubai and Abu Dhabi meteorological stations in the United Arab Emirates. Theoretical models based on Angstrom-Prescott have been applied on data of sunshine hours for the period from 2010 to 2019. The models are developed using 2010 - 2018 data and validated by comparing to the 2019 data. Theoretical solar radiation estimates the maximum of global solar radiation to be in June for both stations, which is in good agreement with the actual data. The performance of the model is tested using statistical indicators such as the coefficient of determination R2 and the Mean Root Square RMSE. The results show that the models were effective enough to describe the global solar radiation with overall R2 of 0.8874 and 0.8706, RMSE of 0.0258 and 0.0241, MBE of 0.0412 and 0.0376, and MPE of 0.2371 and 0.2318, for Abu Dhabi and Dubai meteorological stations, respectively.

Anticoagulation therapy represents a mainstay of treatment and prevention of cardiovascular diseases which are the leading causes of mortality worldwide. In addition, several case reports of spontaneous bleeding occurred linking the consumption of many dietary supplements during treatment with anticoagulants or in postoperative patients. This prompted our study which is conducted on eleven well-known Egyptian medicinal plants to highlight their effect on blood coagulation profile using Prothrombin time (PT) and activated partial thromboplastin time (aPTT) tests. Some of these plants showed interesting results that need more in-depth evaluation of their anticoagulant activity as Hibiscus sabdarifa calyx for its effect on PT. In addition, extracts of Trifolium alexandrinum aerial parts and Pimpinella anismum fruit were proved to affect aPTT. Post operative or cardiovascular patients using herbal supplements should be cautioned about food-drug or herb-drug interactions and to adjust their herbal medication regimen before surgery.
An improved robust variance inflation factor: Reducing the negative effects of good leverage points
Authors:   Dept. of Statistics, Gazi University, Turkey, Ekiz Osman U.
Published: December 2021

In multiple linear regression analysis, the variance inflation factor is a well-known collinearity measure. It is defined as the function of the coefficient of determination between the explanatory variables, and it is based on the maximum likelihood estimator of the regression coefficients. Nevertheless, in addition to outliers, leverage observations can have significant impact on the coefficient of determination, and thereby the variance inflation factor. This study presents an improved robust variance inflation factor estimator that is not affected by these observations. Simulation studies and a real data analysis indicate that the modified robust variance inflation factor estimator performs better than the traditional one.

In this study, poly(methacrylic acid-co-ethylene dimethacrylate (poly(MAA-co-EDMA)) monolith was prepared for the selective adsorption of acidic dye, namely methylene blue (MB), from wastewater. The fabrication of the monolith was carried out by photoinitiation polymerization by irradiating a mixture of methacrylic acid (MAA), ethylene dimethacrylate (EDMA), porogenic solvents and an initiator. Batch adsorption assays were performed to examine the impact of monolith dosage and initial dye concentration on the adsorption capacity and efficiency of the monolith towards MB dye molecules. This adsorption kinetic study revealed that MB adsorption on the monolith followed pseudo-second-order model and equilibrium adsorption behavior was best modeled by Langmuir adsorption isotherm indicating a monolayer adsorption with a maximum adsorption capacity of 50.00 mg g-1. Owing to the presence of negative binding sites on the monolith surface, cationic MB molecules are selectively adsorbed from MB/methyl orange (MO) mixture with an adsorption efficiency of 99.54% at equilibrium time. Moreover, the MB adsorbed monolith was regenerated up to four cycles and the percentage removal efficiency of MB on the monolith dropped to 67.64 % after the fourth cycle. Finally, the monolith effectively adsorbed MB from the tap water in presence of competing ions and the maximum adsorptive capacity obtained was 47.62 mg g-1 with 84.5% adsorption efficiency. Hence, poly(MAA-co- EDMA) monolith is an adequate sorbent for the treatment of cationic dyes in the presence of other dyes and competing ions from wastewater.

The present research work was conducted to improve the phytase production by genetic alteration of Aspergillus niger with induced mutagenesis using solid state fermentation. Strain improvement was carried out in the presence of ultra violet (UV) irradiation and ethylmethane sulphonate (EMS) [0.5% v/v] treatments for various time intervals. We reported an improved strain of Aspergillus niger designated as UV-3 mutant producing a zone of hydrolysis of about 40 mm, in comparison to wild strain (26 mm). The highest enzyme activity was found to be 547.64 IU/g for UV-3 mutant followed by EMS-4 mutant (492.23 IU/g)compared to wild strain which showed 406.45 IU/g of enzyme activity. There was 1.35 fold increase in phytase production after mutation studies of Aspergillus niger. Phytase was applied as poultry feed additive and given to broiler chickens for 5 weeks. The results exhibited that there was increase in body weight gain (BWG) of chicks for experimental group (2028 g) in comparison to control group (1903 g). Thus, physical and chemical mutagenesis was proved as an effective technique for the improvement of strain and ultimately for enhanced and economical phytase production for different industrial applications.

The primary requisite of engineering optical/photonic devices is either for scaling or altering the properties. Here, we present the engineering of ultra-violet (UV) reflectors made up of alternate layers of titania (TiO2) and silica (SiO2) by using the sol-gel spin coating method. The choice of these two materials is appropriate to realize the optical reflectors due to their large refractive index contrast. The formation of multilayer films of TiO2 and SiO2 are studied by field-emission scanning electron microscopy (FESEM), while UV-vis spectroscopy measurement is performed to study the reflectance. By varying the number of TiO2/SiO2 stacks, we have achieved the maximum reflectance within the UV region at center wavelength of 335 nm, 358 nm, and 367 nm corresponding to the 3, 6, and 9 stacks-based reflectors. Finally, we summarize that these reflectors prohibit the propagation of ultraviolet light, and therefore, they are promising as UV protection coating.

How do I Communicate Sringara Rasa (the Emotion Love) Through Pulaneri Vazhakku (Mode of ‘Sensing’)? Experimental Research Study, Practice-Based

Bharathanatyam is practiced for the purpose of experiencing aesthetic pleasure by the actor, dancer and spectator (Rao, 1997). According to ancient treatises such as the Natya Sastra, dancing should be experiential, sensorial and pleasurable. When dance is transmitted, do these core values of the practice get lost? How can we heighten sensorial ranges through the facilitation of a shift in the transmission and dissemination of learning the component Rasa (emotion)? Some of the problems present in the current landscape of learning Bharathantayam is problematic due to the codification of the traditional form and the authoritarian style rooted in its pedagogy. This has left many students feeling incompetent and as a consequence, made the form unattainable. The purpose of my intervention is to make the learning of Sringara Rasa (the emotion of love) a component in the Bharathanatyam curriculum, accessible to all levels of dancers. I hope to achieve this through a sequential model that interrogates cognitive activities present in the engagement of a role or character performing the emotion. My intervention aims at reexamining the theory and practice of Padams (poetic texts) rooted in the Sringara Rasa (emotion of love) and bridging the gaps in learning this component. When dancers introspect, it allows them to access the sensorial dimension of Bharathanatyam.

Building on recent interest in the convergence of arts and sciences, we propose specific areas of intersection between the disciplines of Bharatanatyam, a classical Indian dance, and neuroscience. We present personal reflections by practitioners of both disciplines and propose that Bharatanatyam can be used to understand and explain brain functioning and that neuroscience can help analyze the dancing Bharatanatyam brain. We explore conceptual areas of convergence between the two fields as well as specific points of connection using language acquisition, rhythm, music, and cognition as examples. We conjecture that Bharatanatyam training and practice support long-term neuronal plasticity in various parts of the brain, including but not limited to the hippocampus, motor, premotor cortex, and the cerebellum. The beginning of the study of the intersection between these disciplines will pave the way for additional allied fields of rich thinking, exploration and potentially, therapy.
Haddon matrix analysis of medical preparedness for mass gathering music festivals

Published: December 2021

Beginning in the 1960s as a tool to disaggregate complicated auto injuries, the Haddon matrix has evolved into a modern method of analyzing complex public health challenges. Throughout the United States and internationally, music festivals have become a rapidly growing and increasingly complex area of mass gathering medicine. Given the austere environment and inherent challenges of providing medical care during a music festival, we utilized a modified Haddon matrix. The objective is to assess the relevant human, physical, and sociocultural factors that impact these festivals throughout the pre-event, event, and post-event time periods. This will ensure an all-hazards preparedness approach to the historically high incidence of traumatic injuries and polysubstance abuse, coupled with modern challenges such as infectious diseases and acts of intentional violence.

Objective: To evaluate whether pain management strategies within intensive care unit (ICU) settings contribute to chronic opioid use upon hospital discharge in opioid-naive patients requiring invasive mechanical ventilation. Design: A retrospective, observational study.Setting: An 18-bed mixed ICU at a community teaching hospital located in Brooklyn, New York.Participants: This study included mechanically ventilated patients requiring continuous opioid infusion from April 25, 2017 to May 16, 2019. Patients were excluded if they received chronic opioid therapy at home or expired during this hospital admission. Eligible patients were identified using an electronic health record data query.Main outcome measure(s): The proportion of ICU patients who continued to require opioids upon ICU and hospital discharge. Results: A total of 196 ICU patients were included in this study. Of these, 22 patients were transferred to a regular floor while receiving a fentanyl transdermal patch. However, the fentanyl patch treatment was continued only for three patients (2 percent) at hospital discharge.Conclusions: This retrospective study suggested that high-dose use of opioids in mechanically ventilated, opioid-naive ICU patients was not associated with continued opioid use upon hospital discharge.

Introduction

Systemic lupus erythematosus (SLE) is an autoimmune disorder with a poorly understood aetiology. It predominantly affects females and has a variety of clinical manifestations. In Nigeria, there are limited data on the prevalence and burden of the disease. This study aimed to determine the clinical and laboratory profiles of SLE patients seen in a new rheumatology clinic in South-South Nigeria.

Material and methods

This was a retrospective cross-sectional study conducted over five years (January 2016 to December 2020). The case files of patients that satisfied the diagnosis of SLE were reviewed. The diagnosis was based on the 1997 update of the American College of Rheumatology revised criteria for the classification of SLE. The sociodemographic, clinical, and immunological data were extracted from case records. Data analysis was carried out using IBM SPSS statistics® 2012 version 21.0.

Results

Fifty-two patients were diagnosed with SLE, giving a frequency of 4.7%. Forty-seven (90.4%) of the study participants were females, with a female-to-male ratio of 9.4 : 1. The mean age of the study group was 28.42 years. The mean duration of disease before diagnosis was 4.04 months with a range of 1–15 months. The patients had various organ system manifestations, with polyarthritis being the commonest (86.5%). Others included mucocutaneous (78.8%), haematological (69.2%), serositis (40.4%), renal (38.5%), and neurological (25%) manifestations. Antinuclear antibody (ANA) assay and anti-double-stranded DNA were positive in 100% and 69.2% of patients, respectively. All patients were placed on steroids, and 96.2% had hydroxychloroquine. None of the patients were on biologic disease-modifying antirheumatic drugs.

Conclusions

This study’s results are consistent with data from other African countries. To fully understand the burden and epidemiology of SLE in Nigeria, a larger prospective study is needed.
