Background: COVID-19 is the most common cause of increased levels of cortisol and interleukin 6 (IL-6). The purpose of this pilot study was to examine the effect of home-based resistance training on the serum levels of IL-6 and cortisol in recovered women with COVID-19. Materials and Methods: A pilot randomized controlled design was used. Twenty middle-aged women who recovered from COVID-19 were assigned randomly to the intervention and control groups. The height, weight, and body mass index (BMI) of all participants were measured both before and after the intervention period. Blood samples were taken in the morning to determine the serum levels of IL-6 and cortisol. Fitness (estimated VO2 max) was assessed with a 1.6-km walking test. The intervention group followed eight weeks, three days per week, 1 hour per day of thera-band resistance training and body weight training at home. The control group did not participate in any sports program. Results: At baseline, there were no significant differences between both groups in the mean IL-6, and cortisol levels (P>0.05). After the intervention, the mean IL-6 and cortisol levels significantly decreased in the intervention group (P<0.05). Conclusion: Eight weeks of thera-band resistance band training program and bodyweight workout decreases the serum levels of cortisol and IL-6 and improves the immune system of recovered women with COVID-19. Additionally, there seem to be some indications that this training might have a positive influence on immune function. Further research in this area is highly recommended.
The Recent Drop in Female Labour-Force Participation in Jammu and Kashmir
Authors: Mir Arshid Ahmad , Manzoor Saima
Published: January 2024

The J&K economy will not reach its full potential unless the government and employers remove barriers to women's full labour-force participation in the labour market. Failure to address structural labor market issues, employment policy does more than limit women's career opportunities and aspirations for a better life. In Jammu and Kashmir context overall labor force participation is reported to be considerably low and has been on consistent decline. It has decreased by 7% from 62.09% in 1999-00 to 55.68% in 2017-18. The overall decline in labor force has been mainly attributed to the sharp decline in female labor force participation rate, which has registered almost 8% decline from 39.86% to 31.61% during 1999-00 to 2017-18. This decline is puzzling some and against the gender development goals like inclusive development, women empowerment etc. Women's participation barriers also act as brakes on the national economy, stifling growth. By adopting gender friendly policies and removing barriers to women's participation we can narrow down gender gap in participation and achieve stronger economic growth

The aim of the present article is to investigate of solutions stability of linear autonomous differential equations with retarded argument. The investigation of stability can be reduced to the root location problem for the characteristic equation. For the linear differential equation with several delays it is obtained the necessary and sufficient conditions, for all the roots of the characteristic equation to have negative real part (and hence the zero solution to be asymptotically stable). For the scalar delay differential equation stability domains in the parameter plane are obtained. We investigate the boundedness conditions and construct a domain of stability for linear autonomous differential equation with several delays. We use D-partition method, argument principle and numerical methods to construct of stability domains. In this article, we investigate the solutions stability of linear autonomous differential equations with several delays. It is obtained the necessary and sufficient conditions, for all the roots of the characteristic equation to have negative real part. We investigate the boundedness conditions with the help of argument principle and construct a domain of stability for linear autonomous differential equation with two delays. We use D-partition method, argument principle and numerical methods to construct of stability domains for linear autonomous differential equation with two delays. In the D-partition method, we look for parameter values for which the characteristic equation has at least one zero on the imaginary axis. We consider some examples of equations with two delays. In these cases, the stability domains are limited by two straight lines and a finite number of parametrically defined curves.

The introduction of test automation has numerous advantages in today's world of information technology. These include reducing testing time, simplifying the reporting process, and continuously improving efficiency. The use of test automation opened up the opportunity to thoroughly analyze the differences in the operation of Chrome and Headless Chrome browser interfaces. It was found that the performance of the Headless browser exceeds the performance of its counterpart with a graphical interface by 10.3%. It is important to note that although Headless Chrome is quite effective, it is not always universal for different types of tests. As part of the study, it is justified that the use of Selenium WebDriver for automated testing provides powerful opportunities for performing both routine and complex test tasks that are difficult to perform manually. The choice of this toolkit is due to its multifunctionality, high practicality and compatibility with various programming languages. A detailed analysis of the characteristics and attributes of the test web application was carried out, according to which the software for automating test scenarios was developed for the "trello.com" project, covering web applications that are subject to testing through the user interface. The obtained results made it possible to investigate the speed of Google Chrome and Headless Chrome and establish their advantages and disadvantages. In particular, the disadvantages of the Headless browser are the lack of the ability to use certain functions that are implemented in browsers with a graphical interface, for example, drop-down menus, which can lead to failures in tests. Disadvantages of Real Browser include high resource consumption, environment dependency, instability and complexity of settings. Therefore, the choice of a specific testing technique should depend on the specific requirements of the project, and a combination of Headless and Real Browser testing may be used to obtain optimal results.
Application de la théorie de la taxation optimale à l'impôt québécois
Authors: Bouchard St-Amant Pier-André , Bolduc Nicolas , Ducatel Judelin Michel , Dumais Guillaume
Published: January 2024

Nous appliquons la théorie de la taxation optimale sur le revenu de James Mirrlees (J.A. Mirrlees, « An Exploration in the Theory of Optimum Income Taxation » (1971) 38:2 Review of Economic Studies 175-208) aux données fiscales québécoises. Cette théorie nous fournit un guide normatif pour suggérer des réformes quant à la structure des taux marginaux effectifs d'impositions (TMEI). Contrairement aux taux d'imposition fédéraux et provinciaux, les TMEI permettent de prendre en compte l'ensemble des crédits d'impôt et programmes gouvernementaux, tels que, sans s'y limiter, l'aide sociale, les cotisations obligatoires à l'assurance-emploi, la prime au travail et le bouclier fiscal. Les TMEI traduisent ainsi à quel point le revenu disponible augmente en fonction d'une augmentation du revenu de travail. La question fondamentale de ce document est d'évaluer si l'on peut améliorer la structure des TMEI pour améliorer tantôt l'efficacité, tantôt l'équité de l'économie. Pour ce faire, nous utilisons les statistiques fiscales provenant de l'enquête canadienne sur le revenu de Statistique Canada de 2016 et dérivons des TMEI optimaux, que nous pouvons ensuite comparer aux vrais TMEI au Québec. Les simulations sont effectuées pour deux types de ménages, soit le couple avec deux enfants et l'individu seul. Notre recommandation la plus robuste pour le premier est de réduire ces taux dans la plage de revenu entre 40 000 $ et 50 000 $. Nous montrons également qu'il pourrait être efficient d'augmenter les taux d'imposition chez les parents à revenus plus élevés, selon que le gouvernement ait des préférences redistributives plus élevées, ou selon des paramètres comportementaux des travailleurs. Cette deuxième conclusion est moins robuste et requiert des travaux empiriques additionnels pour être qualifiée de définitive. Pour l'individu seul, l'ensemble des simulations impliquerait d'augmenter le niveau d'imposition dans la plage de revenu entre 60 000 $ et 100 000 $. Nous montrons aussi qu'il pourrait être efficient de diminuer les taux d'imposition pour la plage de revenu entre 35 000 $ et 55 000 $, selon les préférences pour la redistribution du gouvernement et les paramètres des consommateurs. Cette recommandation nécessiterait aussi des travaux empiriques additionnels.
Did the Adoption of BEPS Country-by-Country Reporting Affect Multinational Tax Avoidance? Evidence from Canada
Authors: Maaloul Anis
Published: January 2024

Since 2016, Canadian multinational corporations (MNCs) with consolidated revenues exceeding [euro]750 million (equivalent to Cdn$1.1 billion) in the preceding fiscal year have been subject to country-by-country reporting (CbCR) under Canada's adoption of action 13 of the base erosion and profit shifting (BEPS) project. The objective of this study is to examine empirically whether the adoption of the CbCR obligation has had an impact on the tax-avoidance practices of Canadian MNCs that are subject to this obligation—that is, whether there has been a reduction in tax avoidance by these MNCs since the adoption of CbCR. The study uses a sample that contains all publicly listed Canadian MNCs for a period of 10 years: 5 years before the adoption of CbCR (2011 to 2015) and 5 years after the adoption of CbCR (2016 to 2020). The sample is split into two groups: a treatment sample, which contains all the MNCs subject to the CbCR obligation, and a control sample, which contains all the MNCs that are not subject to this obligation. Using the difference-in-difference method, the study finds no evidence that the adoption of CbCR under BEPS action 13 has had an effect on tax avoidance by Canadian MNCs subject to this obligation. However, additional analyses by sector show that, contrary to expectations, MNCs subject to CbCR in the energy and materials sectors continued to avoid taxes even after the adoption of CbCR in 2016. In other words, the adoption of CbCR seems to have had no deterrent effect on tax avoidance by MNCs subject to this obligation in the energy and materials sectors. Since 2015, these two sectors have also been subject to another type of CbCR under the Canadian Extractive Sector Transparency Measures Act. The study results, which are robust when tested by various measures of tax avoidance and CbCR, provide important feedback to Canadian tax authorities and the Organisation for Economic Co-operation and Development on the effectiveness/ineffectiveness of BEPS action 13.
Policy Forum : Taxation spécifique des carburants — vers une indexation du taux pour en protéger son rendement?
Authors: God Luc , Robert-Angers Michaël
Published: January 2024

Dans cet article, les auteurs constatent une détérioration de la valeur réelle des taxes spécifiques sur le carburant des provinces. Un constat similaire est dressé à l'égard de la taxe d'accise fédérale sur l'essence et le diésel. Pour rappel, les recettes tirées de ces taxes servent notamment au financement de l'entretien et du développement des infrastructures de transport dans une perspective utilisateur-payeur. De plus, celles-ci favorisent une modification des choix à long terme en matière de mobilité, incitant à l'utilisation de modes de transport collectifs, actifs et moins énergivores. Le recours à une formule de taxation ad valorem (utilisée par le passé par certaines provinces) pour assurer le maintien de la valeur d'un prélèvement sur les carburants ajouterait à la volatilité du prix final de ce produit. Toutefois, une indexation annuelle des actuelles taxes volumétriques, comme dans le cas des droits d'accise sur les produits du tabac et les produits alcoolisés, est envisageable. D'ailleurs une telle forme d'indexation est utilisée par certaines juridictions, dont l'Australie.
Policy Forum: Bunching in the Political Contribution Tax Credit Schedule—Theory, Evidence, and Policy
Authors: Hickey Ross , Smith Justin
Published: January 2024

In Canada, the federal government provides non-refundable tax credits for political contributions. The tax credit rate schedule for political contributions has three thresholds, with the tax credit rate decreasing as contributions exceed each threshold. The authors of this article describe how these thresholds have changed over time, their rationale, and their incidence, and provide some evidence that taxfilers respond to the credit rate changes. The authors also describe, by way of comparison, the tax treatment of charitable donations, another voluntary contribution that may be eligible for a non-refundable tax credit.

A Schiff base ligand, 3-((6-amino-1,6-dihydropyridin-2-yl)imino)indolin-2-one, was synthesized by condensing isatin with 2,6-diaminopyridine in this study. Elemental analysis, NMR spectroscopy, and infrared spectroscopy enabled confirmation of the structure of the pyridineincorporated ligand. Additional coordination compounds of this ligand with Mn(II), Co(II), Ni(II), Cu(II), Zn(II), and Cd(II) metals were synthesized with metal-to-ligand proportions verified through trace elemental examinations using CHN. Various spectroscopic techniques including UV-visible absorption spectrophotometry, IR spectrophotometry, electrical conductivity quantifications, melting point determinations, and magnetic susceptibility analyses facilitated characterization of the produced complexes. The antimicrobial potential of the organic ligand and inorganic complexes was screened against Bacillus subtilis and Staphylococcus aureus bacterial strains through the agar disc diffusion technique. Both the uncoordinated ligand and metal-ligand coordination compounds displayed appreciable antibacterial effects on the tested microorganisms. Tetrahedral configurations were proposed for all prepared complexes based on combined analytical and spectroscopic evidence.
NEW p-AMINODIPHENYLAMINE AMIDE COMPOUNDS: DESIGN, SYNTHESIS AND ANTI β-lACTAMASES ACTIVITY EVALUATION
Authors:   Department of Pharmaceutical Chemistry, College of Pharmacy, University of Mosul, Saleh Ahmed A. , Mahmood Ahmed A. J. ,   Department of Pharmaceutical Chemistry, College of Pharmacy, University of Mosul
Published: January 2024

β-Lactams, such as penicillins and cephalosporins, have long been recognized as the most effective antibiotics for the treatment of infectious diseases. However, the major limitation to their effectiveness is the bacterial production of β-lactamase enzymes, which hydrolyze the β-lactam ring in these drugs, rendering them inactive. To overcome this resistance mechanism, β-lactamase inhibitors, such as clavulanic acid, are commonly used in combination with β-lactams. By inhibiting the action of β-lactamase enzymes, these inhibitors restore the efficacy of β-lactam antibiotics. In recent studies, researchers have employed docking techniques to investigate the interaction between β-lactamase enzymes and potential inhibitors. Specifically, the β-lactamases TEM-1 (1pzp) and IMP-1 (1JJE) were used as targets for designing new compounds. A series of novel compounds were generated by synthesizing 6 amides compounds as acid chloride derivatives and reacting them with p-aminodiphenylamine to form amide bonds. These compounds were then characterized by the use of various physical and spectroscopic methods to confirm their structures. Next, the synthesized compounds were subjected to biological testing to evaluate their efficacy against β-lactamaseproducing Gram-positive and Gram-negative bacteria. This was accomplished by determining the minimum inhibitory concentration (MIC) of the compounds against three different strains of bacteria. Additionally, the possible anti β-lactamase activities of the compounds were compared to that of clavulanic acid. The results of this study revealed that five of the synthesized products exhibited effect similar to that of clavulanic acid for only one bacterial strain (Staph. aureus). Furthermore, the findings of the docking study suggest that the β-lactamase active pocket has a preference for hydrophobic substituents, as the synthesized products with these groups showed the highest binding score. In conclusion, the use of β-lactamase inhibitors, such as clavulanic acid, in combination with β-lactam antibiotics has proven effective in combating bacterial resistance. The development of novel compounds with anti β-lactamase activity holds promise for improving the treatment of infectious diseases. By understanding the preferences of the β-lactamase active pocket and designing compounds with hydrophobic substituents, researchers can enhance the affinity and efficacy of these inhibitors. This research contributes to the ongoing efforts to combat antibiotic resistance and improve patient outcomes in the field of infectious disease treatment.
The Distraction Function of Extrafloral Nectaries: Keeping Ants Away From Flowers and Preventing Disruption of Pollination
Authors: Sandoval Molina Mario , González-Camarena Emilio , Rosas-Sánchez Jessica , Janczur Mariusz
Published: January 2024

In exchange for extrafloral nectar, ants deter herbivores from the plants, reducing the amount of herbivory they suffered. However, this defensive mutualism can sometimes have negative effects on plants, as ants may also visit flowers, deterring pollinators and reducing plant fitness. The Distraction Hypothesis posits that extrafloral nectaries (EFNs) have the function of attracting ants and preventing them from visiting flowers and disrupting pollination. In the present study, we tested this hypothesis in the field by conducting an ant-exclusion experiment in Ferocactus recurvus plants. First, we evaluated the effect of ants on pollination. Then, we tested the predictions of the Distraction Hypothesis. Specifically, we hypothesized that ants have a negative effect on plant pollination and that EFNs function to distract ants, keeping them away from flowers and preventing them from disrupting pollination. According to our hypothesis, we found that ant visits to flowers resulted in a decrease in seed production and overall plant fitness. Flowers with ants had fewer seeds and were smaller in size compared to ant-excluded flowers. In accordance with the Distraction Hypothesis, we found that a higher number of EFNs reduced the probability of finding ants on flowers. To minimize ant-pollinator conflict, F. recurvus plants produce EFNs with higher sucrose concentrations, which effectively keep ants away from the flowers. Plant width was found to be positively correlated with the number of EFNs and flowers, and there is an “optimal” number of EFNs that attracts a higher number of ants. Overall, our findings highlight the complex and dynamic nature of interactions between plants, ants, and pollinators, and the potential trade-offs that exist between ant protection and pollinator attraction.

Published: January 2024

The current study assesses the photochemical profiles, the in vitro antioxidant (2,2-diphenyl-1-picrylhydrazyl (DPPH), 2,2'-azino-bis(3-ethylbenzthiazoline-6-sulfonic acid) (ABTS), reducing power ferric and silver nanoparticule) and anti-inflammatory activity of Lantana camara L. leaves and flowers collected from the South of Tunisia. Bioactive extracts of two organs were prepared through an ultrasound-assisted extraction in ethanol. Herein, multivariate statistical analysis was performed to define the relationship between biological activities and the bioactive molecules content and composition. Phytochemical profiling showed higher phenolic and flavonoids contents in leaves extracts than in those obtained from flowers, while the condensed tannins was absent in both organs. LC-MS analysis identified 16 and 15 phenolic compounds from flowers and leaves extracts, respectively. The flowers extract was especially rich in Kaempferol, luteolin-7-O-glucoside, quinic acid and apigenin-7-O-glucoside. Kaempferol, luteolin-7-O-glucoside, quinic acid and syringic acid were identified as the prevalent compounds in leaves extract. The latter exhibited the highest DPPH and ABTS radical scavenging potentials. Whereas flowers extracts revealed the highest reducing potential of ferric and silver ions. However, the leaves and flowers extracts are unable to protect bovine serum albumin (BSA) from thermal denaturation. Furthermore, significant correlations (p < 0.05) were recorded between phytochemical profile and biological activities, as well as between different antioxidant studied assays. The obtained results present practical data for the potential application of L. camara as a sustainable source of multi-functional molecules in food and medicinal industries.

The goal of this instructional style is to help students become more proficient at the floor exercise roll by using a game-based approach and other forms of media. The purpose of this research is to provide evidence for the efficacy of a model for teaching the fundamentals of the floor exercise roll through the medium of a video game in junior high school. Three subject matter experts and three media specialists evaluated the research and validated the learning model using a set of established criteria. This study is occurring within the product development phase with ten stage. A questionnaire was utilised to obtain data for determining the model's accuracy. Descriptive percentages were used to assess the data. The average model validity ratings found in this research show that the material expert validator is 83.33 percent valid and the media expert validator is 89.4 percent valid. The validity score generated by the combination of the three validators is very high quality. Consequently, it is reasonable to infer that the floor exercise roll basic technique learning model based on a game is genuine and can be applied in the context of school-based sports education. Sports educators and curriculum designers can use the favourable feedback from material and media experts to inform the design of more effective learning models for students to become proficient in floor exercises and fundamental rolling technique.

This study aims to determine the impact of using one of the Student Team Achievement Division (STAD) type cooperative learning models on mastery of basic basketball techniques in grade VII junior high school students. This study used an experimental method using a randomize pretest posttest control group design. A total of 75 students were involved in this study, and were divided into two groups, namely 37 experimental groups and 38 people as a control group. The number is obtained from the entire class VII taken using cluster random sampling. The data collection technique uses a type of skill test of basic passing, shooting and dribbling techniques in basketball games that emphasize assessing their movements. The data analysis technique uses the help of the IBM SPSS version 25 program with an independent sample t-test analysis type at a confidence level of 0.05. Based on the results of the analysis obtained, researchers concluded that there is a significant average difference between the STAD type cooperative model and the direct teaching model, where the STAD model has a greater influence on basic basketball technical skills. It is expected that PJOK teachers pay more attention to the characteristics of students, so that they are able to apply models that are in accordance with their characteristics.

The objective of this research is to devise a tool named Vertical Jump Measurement Portable (VJMP) with the purpose of facilitating practical and efficient measurements of vertical jumps, offering portability for use in diverse settings; concurrently, the research aims to evaluate the precision of VJMP in measuring vertical jumps. Employing research and development methodologies, this study involved the comparison of Vertical Jump Measurement Portable (VJMP) research products with traditional vertical jump measuring instruments. The research enlisted 42 participants who were athletes representing diverse sports disciplines. Data analysis included the application of the Mann-Whitney test to discern any statistically significant differences between the two vertical jump measuring instruments, with a threshold for significance set at p>0.05. The study outcomes revealed no statistically significant distinctions in the data obtained from two vertical jump measuring instruments, as indicated by a p-value of 0.754. This underscores the accuracy of VJMP in gauging vertical jumps. Furthermore, the tool exhibited notable efficiency, requiring a mere 41 seconds for the measurement of an individual. In conclusion, VJMP stands as an accurate and efficient instrument for assessing vertical jumps, thereby making it a viable choice for measurements across diverse sports and facilitating ease of use in practical field settings.
Lessons from the calibration and sensitivity analysis of a fish larval transport model

Numerous fish populations show strong year-to-year variations in recruitment. The early life stages play a crucial role in determining recruitment and dispersal patterns. A helpful tool to understand recruitment and dispersal involves simulations with a Lagrangian transport model, which results from the coupling between a hydrodynamic model and an individual-based model. Larval transport models require sound knowledge of the biological processes governing larval dispersal, and they may be highly sensitive to the parameters selected. Various assumptions about larval traits, behaviour and other model parameters can be tested by comparing simulation results with field data to identify the most sensitive parameters and to improve model calibration. This study shows that biological parameterization is more important than inter-annual variability in explaining the year-to-year differences in larval recruitment of common sole in the North Sea and the eastern English Channel. In contrast, year-to-year variability of connectivity leads to higher variability than changes in the biological parameters. The most influential parameters are pelagic larval duration, spawning period and mortality. Calibration over a 12 yr recruitment survey shows that a scenario with low mortality associated with a long larval duration and behaviour involving nycthemeral and tidal migration best reproduces the observations. This research provides insights into factors influencing fish dispersal and recruitment, suggesting a strategy for enhancing the accuracy of models in upcoming studies. The study supports the improvement of larval dispersal modelling by incorporating an easily applicable sensitivity analysis for both calibration and validation. Incorporating sensitivity analyses enhances larval dispersal models, providing performing tools that can contribute to informed fisheries management and understanding of recruitment variability.
Mystifying Photoluminescence Mechanisms

Published: January 2024

Developing quantum dots (QDs) for applications in future devices is a challenge on several frontiers. Control over particle sizes and shapes is essential, but rational design of next-generation QDs also requires a deep understanding of photoluminescence mechanisms. Whereas the scientific community has so far mostly studied the photoluminescence mechanism of quantum-dot structures based on the workhorse material CdSe, there is now a great urge for new types of QDs of different compositions. For instance, we need to explore alternative materials with reduced toxicity, such as the CuInS2- and InP-based QDs that we studied in this thesis. We have shown that optical spectroscopy at the single-particle level is an important technique to uncover the mechanisms of photoluminescence of such QD structures. However, large particle-to-particle variations of emission properties within a batch of nominally identical QDs remain puzzling.

In this thesis, we also studied lanthanide doped materials. These materials have well-defined emission energies that are barely affected by the host crystal in which the lanthanides are incorporated. The general belief is that, just like in bulk crystals, the emission properties of lanthanide ions in nanocrystals (NCs) are independent of their local environment. We challenged this viewpoint, first of all by showing that dopant-to-dopant energy transfer (ET) is hampered in NCs, which alters the photoluminescence output. We also investigated how a special type of ET—from dopant ions to molecular vibrations at the NC surface—quenches the luminescence from specific lanthanide levels. Importantly, once a lanthanide ion has acted as a donor for ET, it can no longer emit light (of the same color), and vice versa. In other words, ET and radiative decay are competing processes, and the PL output is determined by the relative efficiencies of radiative decay and ET.

Sex seems to be a contributing factor in the pathogenesis of bronchial asthma. This study aimed to find sex-related differences in metabolome measured by hydrogen-1 nuclear magnetic resonance (1H NMR) spectroscopy in healthy and ovalbumin (OVA)-sensitized guinea pigs. Adult male and female animals were divided into controls and OVA-sensitized groups. OVA-sensitization was performed by OVA systemic and inhalational administration within 14 days; on day 15, animals were killed by anesthetic overdose followed by exsanguination. Blood was taken and differential white blood cell count was measured. Left lung was saline-lavaged and differential cell count in the bronchoalveolar lavage fluid (BALF) was measured. After blood centrifugation, plasma was processed for 1H NMR analysis. Metabolomic data was evaluated by principal component analysis (PCA). Eosinophil counts elevated in the BALF confirming eosinophil-mediated inflammation in OVA-sensitized animals of both sexes. Sex differences for lactate, glucose, and citrate were found in controls, where these parameters were lower in males than in females. In OVA-sensitized males higher glucose and lower pyruvate were found compared to controls. OVA-sensitized females showed lower lactate, glucose, alanine, 3-hydroxy-butyrate, creatine, pyruvate, and succinate concentrations compared to controls. In OVA-sensitized animals, lactate concentration was lower in males. Data from females (healthy and OVA-sensitized) were generally more heterogeneous. Significant sex differences in plasma concentrations of metabolites were found in both healthy and OVA-sensitized animals suggesting that sex may influence the metabolism and may thereby contribute to different clinical picture of asthma in males and females.
