The effect of intense physical activity session with glutamine supplementation on selected factors of wrestlers' immune system

Athletes with heavy training loads are prone to infectious diseases. It has been shown that these exercises may suppress immune function. The aim of this study was to investigate the effect of one session of intense physical activity with glutamine supplementation on selected factors of wrestlers' immune system. For this purpose, 20 wrestlers were selected and randomly divided into two groups of supplement and placebo. The first blood sample was taken from the subjects. Then they did the Bruce test. Immediately after the end of the test, blood samples were taken from the subjects for the second time and then to the supplement group. The glutamine supplement was given the same amount of maltodextrin per kilogram of body weight and the placebo group. Blood samples were taken from the subjects for the third and fourth time 1 and 2.5 hours after taking the supplement or placebo. After measuring blood factors, the findings were statistically analyzed (ANOVA) at a significance level of p <0.05. The results showed that the percentage of neutrophils in the supplement group increased significantly 2.5 hours after supplementation compared to immediately after exercise and 1 hour after supplementation. This increase was less in the supplement group than in the placebo group. The percentage of lymphocytes in the supplement group decreased significantly 2.5 hours after supplementation compared to the pre-test, immediately after exercise and 1 hour after supplementation, which was less in the supplement group than the placebo group. The percentage of monocytes in the supplement group increased significantly 2.5 hours after supplementation compared to immediately after exercise. This increase was less in the supplement group than in the placebo group. The results of this study showed that glutamine supplementation during strenuous exercise has beneficial effects on the immune system of athletes.

The Potential Re-Use of Saudi Mine Tailings in Mine Backfill: A Path towards Sustainable Mining in Saudi Arabia

The Kingdom of Saudi Arabia covers an area of approximately 2 million km2 and is rich in natural resources that are necessary for industrial development. The estimated mineral wealth beneath the Kingdom’s soil is approximately USD 1.33 trillion, as reported by the Ministry of Industry and Mineral Resources. The Kingdom’s vision for 2030 is to develop the mining sector to become the third pillar of the domestic economy. Therefore, exploration and mining activities are expected to accelerate over the next decade, which will lead to increased waste production. New executive regulations issued in January 2021 contain several sustainable elements related to the environment, social responsibility, and occupational health and safety. Therefore, this study aims to promote an example of sustainable mining activities in the Kingdom that could be adapted to meet the regulatory requirements. Cemented paste backfill samples of varying composition were made with waste materials from a Saudi copper mine for re-injection into underground mining cavities to minimize waste exposure to the environment. The samples were tested for unconfined compressive strength (UCS) after 7, 14, 28, 56, and 90 days of curing. Results from a statistically designed experiment technique show that the samples developed sufficient strength to be used in mine backfilling applications. Strong negative relationships were detected between the UCS and the water-to-binder ratio. There is strong potential for mine backfill technology to be applied to a wide range of Saudi Arabian mines to enhance the sustainability of the mining sector.

Effects of Process Parameters on the Activities of Enzymes by Different Species of Aspergillus in Crude Polluted Soil Sites

The effects of temperature, pH and incubation time on amylase, protease and cellulase activity by different species of Aspergillus in crude oil polluted soil sites in Nigeria were studied. Incubation period, Optimal pH values and temperatures for the enzymes produced by the different micro‐organisms were determined. The production of amylase by A. fumigatus and A. niger isolated from crude oil polluted sites showed that both fungi had their peaks on the first day of incubation for amylase, protease and cellulase. A. niger showed higher stability across a range of pH (3-6) and temperature (25-70oC) changes in all the enzyme activities. Further experiments are recommended to purify the secreted enzymes and stability studies will be performed to enhance the application of enzyme to commercial level.
First-order and second-order necessary optimality conditions concerning components for discrete-time stochastic systems

This paper deals with the first-order and second-order necessary optimality conditions concerning the components for discrete-time stochastic systems under weakened convexity assumptions. By means of a new discrete-time backward stochastic equation, we establish a first-order necessary optimality condition concerning every component in the form of a global stochastic maximum principle. Besides, we also obtain an optimality condition concerning one component of vector control in the form of a global stochastic maximum principle and concerning the other in the form of linearised stochastic maximum principle. Moreover, by introducing a new discrete-time backward stochastic matrix equation, we derive diverse second-order necessary optimality conditions of singular and quasi-singular controls concerning the components.
Photothermally active borosilicate-based composite bone cement for near-infrared light controlled mineralisation

ABSTRACT The mineralisation and ion release behaviour of the bioactive glasses play a crucial role for their biomedical applications. It is, however, difficult to control these processes artificially in situ. Herein we utilised NIR radiation as an external stimuli to tailor these processes to match specific requirements. Therefore, the composite bone cements based on borosilicate glass incorporated with TiN NPs were fabricated. It is found that, under 1064 nm laser irradiation, the composite bone cements exhibited remarkable photothermal performance and the cumulative amount of silicon, boron and calcium ions of the composite bone cement increased by 4.74, 1.79, and 1.26 times within 10 days, respectively. Even at the later stage of mineralisation, the ions release rates could be accelerated. Additionally, 1064 nm laser irradiation accelerated the formation of HA. Therefore, this paper provided an effective way to regulate the mineralisation and ion release behaviour of bioactive glass after implantation.
Sulphide geochemistry of the superlarge Tiegelongnan Cu (Au) deposit in Tibet, China: Implication for the mineralization process

The Tiegelongnan deposit in central Tibet presents a typical high‐sulfidation porphyry Cu (Au) mineralization system. Optical microscopy, scanning electron microscopy–energy dispersive spectrometry (SEM–EDS), and laser ablation inductively coupled plasma mass spectrometry (LA–ICPMS) were used to understand the mineralization processes. The advanced argillic alteration zone directly contacts the phyllic alteration zone, which is linked to the Early Cretaceous porphyritic intrusions. In this study, the spatial distributions of chief copper sulphides with variable gangue minerals are illustrated. The deep inner phyllic zone typically produced an end‐member assemblage of chalcopyrite–sericite (±dolomite), which trended upwards to produce more bornite–sericite (±siderite ± magnesite), and subsequently, the advanced argillic alteration yielded the representative end‐member assemblage of tennantite–alunite ± (aluminium‐phosphate‐sulphate, namely, APS, ±kaolinite). In the phyllic–advanced argillic transition zone, intensive covellite precipitation with the widespread occurrence of sericite–kaolinite (±APS) assemblage is proposed as an important feature in this study, which is mainly produced on the southwest side of the ore‐body centre. The typical co‐occurrence of chalcopyrite with dolomite at great depths indicates that it was related to a gently acidic fluid containing CO2; however, the pervasive tennantite–alunite association present at shallower levels suggests that fluids with SO2 were mainly involved and produced stronger acidic conditions. Acidic fluids are demonstrated to highly accelerate water‐rock alteration. Trace element analyses of the copper sulphides reflect that Au concentrations of bornite and tennantite are higher than chalcopyrite and covellite and present small signal variations. Moreover, comparing the presence of micron‐sized Au‐telluride in tennantite under advanced argillic alteration with the nano‐sized native gold in bornite resulting from phyllic alteration suggests that to a certain extent, Au enrichment is affected by the shift of more Te contents in fluid towards shallower levels, which could promote Au precipitation. Additionally, the Se contents of the selected samples were typically concentrated in chalcopyrite, bornite, and covellite, which yielded contents an order of magnitude greater than those in tennantite, indicating the intimate hydrothermal origin of the first three sulphides. Overall, the sulphide–gangue mineral associations and their copper sulphide geochemistry indicate that the hypogene–chalcopyrite of low Au contents from the phyllic zone closely corresponds to the action of gentle acidic fluids with CO2, while more acidic fluids with SO2 are involved in the formation of supergene tennantite with relatively high values of Au and Te in the advanced argillic alteration.

Floral complexity can help maintain plant diversity by inducing pollinator specialization

The global decline in plant biodiversity throughout recent human history has attracted broad scientific attention, as biodiversity plays a key role in promoting a productive ecosystem. Pollination is a major factor in plant survival but carries an additional cost for locally rare plant species: they are likely to receive high levels of incompatible pollen that does not contribute to reproduction and can even impair seed production. Therefore, floral traits that diminish the risk of incompatible pollen receipt may be favoured by natural selection. We developed a theoretical framework to explore the influence of floral morphological complexity on competition for pollinator services between self‐incompatible simultaneously flowering plant species. We show that when a rare plant species is morphologically complex, it may persist in competition with a more common species. Synthesis. The results show that, through its influence on pollinator foraging behaviour, complex floral morphology can contribute to the maintenance of plant diversity.
Prognostic Impact of Tumor Budding on Moroccan Colon Cancer Patients

Background Tumor budding is now emerging as one of the robust and promising histological factors that play an important role in colon cancer. In this study, we aimed to investigate the association between tumor budding and tumor clinicopathological factors, tumor molecular signature, and patient survival for the first time in a Moroccan population. Methods We collected data of 100 patients operated from colon adenocarcinoma. Tumor budding was assessed on HES slides, according to the International Tumor Budding Consensus Conference 2016 recommendations. The expression of MMR proteins was performed by immunohistochemistry. KRAS and NRAS mutations testing was performed by Sanger sequencing and pyrosequencing. Results High tumor budding grade (BUD 3) was found to be significantly associated with adverse clinicopathological features including older age (P=0.03), presence of perineural invasion (P=0.02), presence of vascular invasion (P=0.05), distant metastases (P < 0.001), advanced TNM stage (P=0.001), the occurrence of relapse (P=0.04), and the high number of deceased cases (P=0.02). Interestingly, we found that tumors with high-grade tumor budding were more likely to be microsatellite stable (MSS) (P=0.005) and harbor more KRAS mutations (P=0.02). Tumors with high-grade tumor budding were strongly associated with KRAS G12D mutation (P=0.007). In all stages, high tumor budding was correlated with poorer overall survival (P=0.04) and decreased relapse-free survival with a difference close to significance ((P=0.09). We concluded that high tumor budding was strongly associated with unfavorable clinicopathological features and special molecular biomarkers and effectively affects the overall survival of CC patients. Conclusions Based on these findings and the ITBCC group recommendations, tumor budding should be taken into account along with other clinicopathologic factors in the risk assessment of colorectal cancer.
Selecting optimum levels of wavelet multi‐resolution analysis for time‐varying signals in structural health monitoring

Although the effectiveness of discrete wavelet transform (DWT) for analyzing time‐varying measurements has been studied for mechanical and civil engineering applications, a few fundamental questions still need to be answered, such as how to choose an optimal decomposition level (DL) for a specific task. Selection of the optimal DL still remains a question that has not been adequately explored and not thoroughly investigated. Vast majority of wavelet based methods in mechanical and civil engineering applications have been associated with nonstationary measurements and do not offer detail information on how DL should be selected or linked to useful features that can identify anomalies in a structure. This study proposes a new detailed framework for choosing the optimal DL to guarantee an effective wavelet analysis for time‐varying structural responses. The approach proposed in this paper uses various wavelets and theoretical levels to decompose the signal and to identify those aspects that interact to affect the DL, such as data characteristics, frequency band features, noise reduction, similarity, sharing information, and reconstruction quality. To show the effectiveness of our proposed method, we considered a comparative study using various mother wavelets on El Centro earthquake and acceleration responses from shaking table results of physical experiment. Experimental results show that the optimal DL for El Centro earthquake is 4 and for the acceleration data is 6. These results obviously demonstrate the stability and the robustness of the proposed method in the analysis of contaminated time‐varying signals.
An Improvement of Ant Colony Adhoc On-Demand Vector (ANT-AODV) with K-Means Clustering Nodes Method in Mobile Adhoc Network (MANET) Environment

MANET (Mobile Ad hoc Network) is a technology used for data communication on mobile media. MANET moves and speeds also randomly with different distances between nodes. In the AODV reactive protocol, the development of a routing protocol with an ant colony model can significantly improve performance. The measurement results will impact the decision on the development of the ant colony protocol implemented in AODV to obtain the best route for data transmission. Several studies have developed the K-Means clustering method to obtain the shortest and best route from the AODV protocol. It does not measure congestion, distance, energy, and signal strength of the wireless network. In this research, a combination of methods was carried out, by combining clustering and also ant colony method to get the best route while dealing with the problems that have been mentioned. Implementation is done by modifying the AODV protocol and adding the two methods. At the end of the research, metric measurements were carried out to determine the Packet Delivery Ratio, End to End Delay and also the Average Hop Count.
Recovering "Lay Ignorance" in the Stanford Financial Group Ponzi Scheme

Abstract:The Stanford Financial Group's 2009 collapse devastated more than 20,000 depositors across the Americas. News stories portrayed the $7.2 billion fraud as an elaborate production of ignorance, and its middle-class marks as silent dupes. Media accounts thus differed little from dominant schools of ignorance scholarship, which have emphasized how powerful organizations use their expertise to foist ignorance on passive publics. However, the notion that laypeople are voiceless in such processes is empirically and theoretically untenable. Drawing on interviews with 103 defrauded Stanford clients in the US and Venezuela, this article shows that laypeople play an active interpretive and storytelling role in producing "lay ignorance" in the course of transacting with institutions, personnel, technologies, or products they lack the means to comprehend. Repurposing the concept of "jurisdiction," I frame "layperson" as a role marked by its distance from the forms of authority that comprise expertise. As my comparison of US and Venezuelan investors reveals, laypeople nonetheless stitch surrogate forms of normative and epistemic authority from inapposite sources to produce their "lay ignorance. " The resulting accounts, I demonstrate, draw opportunistically from laypeople's institutional, cultural, and political contexts.

Results: The results of data analysis showed a direct, positive, and significant linear relationship between spiritual intelligence and clinical competence of all students (P < 0.05). According to the students' self-report, the highest mean score of clinical competency of the students was related to medical students with a mean score of 37 and the lowest to the laboratory students with a mean score of 30 (P =0.012). In addition, the results showed that the highest mean score of spiritual intelligence belonged to nursing students with a score of 48 (good spiritual intelligence) and the lowest to radiology students with a score of 39 (moderate spiritual intelligence) (P =0.019). Conclusion: We found that there is a direct and positive correlation between spiritual intelligence and clinical competence, so it seems that promoting spiritual intelligence may be associated with an increase in clinical competence.
A Review of the Electrophysiological Neuroprognostications after Out of Hospital Cardiac Arrest

This personal opinion review of the potential role for EEG in the multimodal neuroprognostication of comatose cardiac arrest patients, after resuscitation and targeted temperature management, discusses recent findings along with our personal experience from a large single-center cohort of 220 consecutive patients investigated with electrophysiological tests (EEG and SSEP). Although EEG has its limitations, along with all modalities in the multimodal prognostic framework, when timed appropriately and interpreted in a standardized fashion, it can be probabilistic but not deterministic of an individual patient’s neurological prognosis. The EEG phenotype can indicate both good and poor prognoses for a comatose patient on the Intensive Care Unit, which is a distinct advantage of this widely available modality, whilst an SSEP can reliably predict a poor outcome if absent and may also help predict good outcome using amplitude analysis.
