Net Primary Production and Ecosystem Carbon Flux of Brazilian Tropical Savanna Ecosystems From Eddy Covariance and Inventory Methods

Estimates of net primary (NPP) and ecosystem production (NEP) are needed for tropical savanna, which is structurally diverse but understudied compared to tropical rainforest. We used eddy covariance and inventory methods to estimate carbon (C) fluxes for an upland mixed grassland and a seasonally flooded forest to determine the correspondence between these methods and assess the contribution of C cycling components to the total NPP. Both techniques provided similar estimates of net ecosystem CO2 exchange (−3.0 ‒ 2.3 MgC ha−1 y−1 for eddy covariance vs. −2.0 ‒ 4.3 MgC ha−1 y−1 for inventory), gross primary production (7.5–16.3 MgC ha−1 y−1 for eddy covariance vs. 8.7–18.4 MgC ha−1 y−1 for inventory), and total NPP (0.9–7.5 MgC ha−1 y−1 for eddy covariance vs. 2.0–9.5 MgC ha−1 y−1 for inventory). Belowground NPP accounted for 49%–53% of the total NPP for both ecosystems, followed by aboveground litter (26%–27%) and wood (16%–17%) production. Increases in water availability increased the potential for C storage, but the mechanism was different in the savanna types. Compared to other savanna ecosystems, the mixed grassland had a lower productivity and C use efficiency (CUE = NPP/GPP = 0.28), while the Cerrado forest had a high CUE (0.58) and similar C flux rates to other tropical savanna forests. The agreement in the C cycle estimates derived from the eddy covariance and inventory methods increases our confidence in the productivity estimates for these tropical savanna ecosystems.
The WD40-Protein PfWLP1 Ensures Stability of the PfCCp-Based Adhesion Protein Complex in Plasmodium falciparum Gametocytes

Members of the WD40-repeat protein family can be found in all eukaryotic proteomes where they usually serve as interaction platforms for the assembly of large protein complexes and are therefore essential for the integrity of these complexes. In the malaria parasite Plasmodium falciparum, the WD40-repeat protein PfWLP1 has been shown to interact with members of distinct adhesion protein complexes in the asexual blood stages and gametocyte stages. In this study, we demonstrate that the presence of PfWLP1 is crucial for both the stability of these gametocyte-specific adhesion complexes as well as for gametocyte maturation and gametogenesis. Using reverse genetics, we generated a PfWLP1-knockdown parasite line for functional characterization of the protein. Knockdown of PfWLP1 resulted in a slight reduction of gametocyte numbers and significantly the impaired ability of the gametocytes to exflagellate. PfWLP1-knockdown further led to reduced protein levels of the Limulus coagulation factor C-like (LCCL)-domain proteins PfCCp1 and PfCCp2, which are key components of the adhesion complexes. These findings suggest that the interaction of PfWLP1 with members of the PfCCp-based adhesion complex ensures complex stability and thereby contributes to gametocyte viability and exflagellation.
A Deep Learning Algorithm for Detecting Acute Pericarditis by Electrocardiogram

(1) Background: Acute pericarditis is often confused with ST-segment elevation myocardial infarction (STEMI) among patients presenting with acute chest pain in the emergency department (ED). Since a deep learning model (DLM) has been validated to accurately identify STEMI cases via 12-lead electrocardiogram (ECG), this study aimed to develop another DLM for the detection of acute pericarditis in the ED. (2) Methods: This study included 128 ECGs from patients with acute pericarditis and 66,633 ECGs from patients visiting the ED between 1 January 2010 and 31 December 2020. The ECGs were randomly allocated based on patients to the training, tuning, and validation sets, at a 3:1:1 ratio. We used raw ECG signals to train a pericarditis-DLM and used traditional ECG features to train a machine learning model. A human–machine competition was conducted using a subset of the validation set, and the performance of the Philips automatic algorithm was also compared. STEMI cases in the validation set were extracted to analyze the DLM ability of differential diagnosis between acute pericarditis and STEMI using ECG. We also followed the hospitalization events in non-pericarditis cases to explore the meaning of false-positive predictions. (3) Results: The pericarditis-DLM exceeded the performance of all participating human experts and algorithms based on traditional ECG features in the human–machine competition. In the validation set, the pericarditis-DLM could detect acute pericarditis with an area under the receiver operating characteristic curve (AUC) of 0.954, a sensitivity of 78.9%, and a specificity of 97.7%. However, our pericarditis-DLM also misinterpreted 10.2% of STEMI ECGs as pericarditis cases. Therefore, we generated an integrating strategy combining pericarditis-DLM and a previously developed STEMI-DLM, which provided a sensitivity of 73.7% and specificity of 99.4%, to identify acute pericarditis in patients with chest pains. Compared to the true-negative cases, patients with false-positive results using this strategy were associated with higher risk of hospitalization within 3 days due to cardiac disorders (hazard ratio (HR): 8.09; 95% confidence interval (CI): 3.99 to 16.39). (4) Conclusions: The AI-enhanced algorithm may be a powerful tool to assist clinicians in the early detection of acute pericarditis and differentiate it from STEMI using 12-lead ECGs.
The Effect of the Addition of Ozonated and Non-Ozonated Fruits of the Saskatoon Berry (Amelanchier alnifolia Nutt.) on the Quality and Pro-Healthy Profile of Craft Wheat Beers

Research into the suitability of domestic raw materials, including, for example, new wheat cultivars and fruit additives for the production of flavoured beers, is increasingly being undertaken by minibreweries and craft breweries. The fruits of the Saskatoon berry are an important source of bioactive compounds, mainly polyphenols, but also macro- and microelements. The fruits of two Canadian cultivars of this species, ‘Honeywood’ and ‘Thiessen’, were used in this study. Physicochemical analysis showed that wheat beers with the addition of non-ozonated fruit were characterised by a higher ethanol content by 7.73% on average. On the other hand, enrichment of the beer product with fruit pulp obtained from the cv. ‘Thiessen’ had a positive effect on the degree of real attenuation and the polyphenol profile. Sensory evaluation of the beer product showed that wheat beers with the addition of ‘Honeywood’ fruit were characterised by the most balanced taste and aroma. On the basis of the conducted research, it can be concluded that fruits of both cvs. ‘Honeywood’ and ‘Thiessen’ can be used in the production of wheat beers, but the fermentation process has to be modified in order to obtain a higher yield of the fruit beer product.
Multi-dimensional radiative transfer in circumstellar disks

In this thesis a radiative transfer model for the simulation of protoplanetary disks was developed. As a basis served the general stellar atmosphere package PHOENIX (Hauschildt et al. 1999). Substantial modifications accounting for accretion disk properties have been implemented. The disk is divided into rings and the vertical structure is calculated for each one. A summation of all rings gives a so-called 1+1D disk structure description. The models have been tested and were confronted with high-resolution infrared spectra of the inner disk of T Tauri stars which display rich molecular emission line spectra. The models can reproduce the observational data nicely identifying the properties of the gas in the disk. Furthermore, the simulation of the radiative transfer was extended to 3 dimensions providing a more realistical treatment of the problem. Two major projects were followed with this method. On the one hand, the influence of disk asymmetries, caused e.g. by planets, on the line profile were investigated by means of a 2-level model atom. Second, the influence of the radial radiative transfer of the disk structure was simulated using an iterative method employing both the 1D code for the determination of the hydrostatic equilibrium and the calculation of the opacities as well as the 3D code for the radiative transfer and the temperature correction. The former simulation showed that line asymmetries caused by density waves in the inner disks can be detected in some cases. The latter demonstrated that the disk is heated by radial diffusion leading to a measurable vertical blow-up.
Temporal associations between objectively measured physical activity and depressive symptoms: An experience sampling study

Background This study aimed to examine the relationship between the timing of physical activity and within-individual differences in depressive symptoms, positive affect, and negative affect in individuals with different baseline levels of depressive symptoms. Methods Experience sampling methodology (ESM) was used to measure real-time depressive symptoms, positive affect, and negative affect in a convenience sample of 78 healthy adults (aged M = 25.46 years, SD = 6.18; 57 females) five times per day for 14 days. We measured physical activity throughout the 14 days by using activity sensors. Baseline levels of depressive symptoms were assessed with the PHQ-9 to build subgroups with low vs. mild-moderate depressive symptoms. Results Physical activity predicted decreased depressive symptom levels, negative affect, and increased positive affect. Associations were stronger for individuals with higher baseline levels of depressive symptoms and for physical activity between 0 and 30 min compared to physical activity between 30 and 180 min before the mood rating. Conversely, levels of depressive symptoms, positive and negative affect did not predict physical activity. Limitations The convenience sample may not have been representative of the general population or people with depression. Accelerometers may not have detected some types of physical activities such as bicycling. Causality could not be inferred because of the observational study design. Conclusion Individuals with higher levels of depressive symptoms may benefit from physical activity. While the effects were strongest for physical activity immediately before the mood ratings, the effects were in the same direction for up to 3 h before the mood ratings.
When indicators fail: SPAR, the invisible measure of pandemic preparedness

Recent literature on indicators as technology of global governance has shown the power of numbers in shaping knowledge and policy priorities. But not all indicators have powerful effects; some remain invisible. Are such indicators an obverse of powerful indicators? Are the same process of indirect exercise of power to indirectly achieve social and economic effects at work? This paper explores the case of Sustainable Development Goal (SDG) indicator 3.d. 1 for the target to build national capacity for pandemic preparedness (target 3d) as a case study of invisible indicators. This indicator has had little traction, despite its relevance in the context of the Coronavirus disease 2019 (COVID-19) pandemic. The paper explores the reasons that explain this paradox through the framework of epistemic infrastructures. It argues that the indicator—the State Party Self-Assessment Report (SPAR) score—was an inconvenient tool for the powerful actors in the global health community as it turned out to be an extremely poor predictor of COVID-19 response performance. It would have exposed not only the failings of the powerful countries that lead the policy agenda for pandemic preparedness but also the legitimacy of their expertise and the paradigm of global health security as an approach to governing health risks. The analysis highlights the tight relationship between power and the use of indicators in global governance. While indicators are increasingly used by powerful actors to reframe policy narratives, the indicator of pandemic preparedness has been kept invisible to maintain their existing framing. It thus illustrates the resilience of power structures in epistemic infrastructures.
Coherent States of a Charged Particle in a Magnetic Field

IN the papers by Schwinger and Glauber [1, 2 J coherent states of electromagnetic radiation were introduced which were afterwards studied in a number of papers. l3 ' 4 J Coherent states in quantum optics are constructed by analogy with the coherent states of a quantum oscillator which were first considered by Schrodinger. l5 J We consider the problem of a charge in a magnetic field. This problem was considered in the nonrelativistic case in papers by Kennard, lsJ Darwin, £7J and Landau l8 J and in the relativistic case in papers by Rabi, l9J and Johnson and Lippmann. UoJ Since it is well known l 11 J that the problem of a charged particle in a uniform magnetic field or in crossed uniform electrical and magnetic fields (EH = 0, E 2 H2 < 0) reduces to solving an equation for the wave function of the oscillator type (Landau was the first to obtain this result when evaluating the spectrum of the problem under consideration l 8 J) it is natural, as was noted earlier, l 12J to introduce coherent states into this problem and to consider them. The aim of the present paper is a consideration of the properties of coherent states of a charged particle (relativistic or non-relativistic) in a uniform magnetic field. Since in what follows it is necessary to use the problem of a quantum oscillator we briefly remind ourselves of the results referring to the coherent states of an oscillator. A similar derivation and discussion of these results is given in Glauber's book. l 13 J The equation for the wave function of a one-dimensional oscillator has the form [11 J
Identification of RNA Markers in Red Blood Cells for Doping Control in Autologous Blood Transfusion

The World Anti-Doping Agency (WADA) has prohibited the use of autologous blood transfusion (ABT) as a doping method by athletes. It is difficult to detect this doping method in laboratory tests, and a robust testing method has not yet been established. We conducted an animal experiment and used total RNA sequencing (RNA-Seq) to identify novel RNA markers to detect ABT doping within red blood cells (RBCs) as a pilot study before human trials. This study used whole blood samples from Wistar rats. The whole blood samples were mixed with a citrate–phosphate–dextrose solution with adenine (CPDA) and then stored in a refrigerator at 4 °C for 0 (control), 10, or 20 days. After each storage period, total RNA-Seq and bioinformatics were performed following RNA extraction and the purification of the RBCs. In the results, clear patterns of expression fluctuations were observed depending on the storage period, and it was found that there were large numbers of genes whose expression decreased in the 10- and 20-day periods compared to the control. Moreover, additional bioinformatic analysis identified three significant genes whose expression levels were drastically decreased according to the storage period. These results provide novel insights that may allow future studies to develop a testing method for ABT doping.
Nutritional Education and the State of Oral Health in Adolescents

Background. Health promotion of adolescents is a high priority in Poland. Epidemiological data still indicates the low effectiveness of the health care system in this area. The relationship between the state of oral health and the vocational education of adolescents seems to be justified. The objective is to evaluate changes in the oral health status, eating habits, and the relationship between oral health and lifestyle related to vocational education among students from a secondary technical school of gastronomy and electro-engineering and information technology. Methods. The study consisted of two stages (at the beginning and end of education) and two parts: a questionnaire and a dental examination. The study group initially included 55 male students from the secondary technical school of gastronomy and 54 in electro-engineering and information technology school. In the second stage of the study, it was 42 and 51, respectively. Results. After three years, in the engineering and information technology group, compared to gastronomy one, a statistically significant increase in caries prevalence and the number of students eating between meals was observed. Conclusions. Professional education on proper nutrition conducted in the gastronomic school could have a decisive impact on the better oral health status of students.
Socio-economic disparity in food consumption among young children in eight South Asian and Southeast Asian countries

BACKGROUND/OBJECTIVES This study examined socio-economic differences in diverse food consumption among children 6–23 months of age in South Asia and Southeast Asian countries. SUBJECTS/METHODS Data from Demographic and Health Surveys in four countries in South Asia (n = 15,749) and four countries in Southeast Asia (n = 10,789) were used. Survey-design adjusted proportions were estimated for the following 10 food items: grains, legumes, dark green leafy vegetables (DGLV), vitamin A-rich fruits, vitamin A-rich vegetables, other fruits and vegetables (OFV), fish, meat, dairy, and eggs. An equity gap was defined as an arithmetic difference in the proportion of each food item consumed in the past 24-hours between the wealthiest and lowest quintiles and between rural and urban areas, denoted by percentage points (pp). RESULTS The consumption of most of the 10 food items was higher in the wealthiest quintiles and urban areas across eight countries. The size of equity gaps was greater in Southeast Asia than in South Asia, particularly for vitamin A-rich fruits (3.3–30.0 pp vs. 0.3–19.6 pp), vitamin A-rich vegetables (12.1–26.7 pp vs. 2.4–5.9 pp), meat (17.7–33.4 pp vs. 3.4–13.4 pp), and dairy (14.7–32.5 pp vs. 3.3–11.4 pp). However, the size of equity gap in egg consumption was greater in Southeast Asia than South Asia (11.2–19.8 pp vs. 11.0–26.7 pp). Relatively narrower gaps were seen in the consumption of grains (0.3–12.9 pp), DGLV (0.6–12.4 pp), and fish (0.1–16.8 pp) across all countries. CONCLUSIONS Equity gaps in food consumption differed by socio-economic status and region. Reducing equity gaps in nutrient-rich foods and utilizing regionally available food resources may increase child dietary quality.
Antiviral Effect of hBD-3 and LL-37 during Human Primary Keratinocyte Infection with West Nile Virus

West Nile virus (WNV) is an emerging flavivirus transmitted through mosquito bites and responsible for a wide range of clinical manifestations. Following their inoculation within the skin, flaviviruses replicate in keratinocytes of the epidermis, inducing an innate immune response including the production of antimicrobial peptides (AMPs). Among them, the cathelicidin LL-37 and the human beta-defensin (hBD)-3 are known for their antimicrobial and immunomodulatory properties. We assessed their role during WNV infection of human primary keratinocytes. LL-37 reduced the viral load in the supernatant of infected keratinocytes and of the titer of a viral inoculum incubated in the presence of the peptide, suggesting a direct antiviral effect of this AMP. Conversely, WNV replication was not inhibited by hBD-3. The two peptides then demonstrated immunomodulatory properties whether in the context of keratinocyte stimulation by poly(I:C) or infection by WNV, but not alone. This study demonstrates the immunostimulatory properties of these two skin AMPs at the initial site of WNV replication and the ability of LL-37 to directly inactivate West Nile viral infectious particles. The results provide new information on the multiple functions of these two peptides and underline the potential of AMPs as new antiviral strategies in the fight against flaviviral infections.
Antibody-drug conjugates in cancer

Antibody drug conjugates (ADCs) are emerging as powerful anti-cancer treatments. They are designed to combine the tumor specificity, pharmacokinetics and biodistribution properties of antibodies with the potent cell-killing activity of small molecules. The approval of brentuximab vedotin (Adcetris) for the treatment of Hodgkin lymphoma and trastuzumab emtansine (Kadcyla) for the treatment of metastatic breast cancer has spurred clinical development of ADCs. As the field of ADCs is rapidly emerging, a better understanding of the requirements needed for optimal intracellular delivery of ADCs seems mandatory. The aim of this thesis was to better understand the antibody and antigen requirements that are needed for effective ADC treatment. Different tumor antigens and targeting antibodies were compared for their capacity to deliver a cytotoxic payload to tumor cells, uncovering general mechanisms. In the course of this work, TF was identified as an excellent ADC target because of its rapid internalization and lysosomal targeting characteristics. Furthermore we have explored a novel Ab platform that improves the intracellular delivery of cytotoxic payloads. These findings provide a better insight in the Ab and antigen requirements needed for optimal payload delivery and support the development of novel and further improved ADCs for the treatment of cancer.
Learning Management Systems Adoption Conundrums; Technological and Pedagogical Dilemmas that arise for Higher Education

Technology is used in many higher learning institutions for a multitude of reasons including distributing learning materials, organizing group projects, calculating grades, facilitating online discussions, turning in homework, creating class content, etc. When these separate technologies merge in one place, it is called a Learning Management System (LMS). Implementing an LMS in Higher Education can enhance a learning environment and assist in deploying pedagogy in a positive and efficient way while engaging students. However, there are dilemmas that arise that can hinder the solution that the technology seeks to solve. This paper discusses the divides created by the pedagogical and technological interests of LMS adoption in higher education and outlines future research needed for more successful implementation and subsequent continued use. In a sea of options, the solutions that are strongest include individual customization flexibility and have strong peer support; these are the ones that seem to last.
Cocktails of Mycotoxins, Phytoestrogens, and Other Secondary Metabolites in Diets of Dairy Cows in Austria: Inferences from Diet Composition and Geo-Climatic Factors

Dairy production is a pivotal economic sector of Austrian and European agriculture. Dietary toxins and endocrine disruptors of natural origin such as mycotoxins and phytoestrogens can affect animal health, reproduction, and productivity. This study characterized the profile of a wide spectrum of fungal, plant, and unspecific secondary metabolites, including regulated, emerging, and modified mycotoxins, phytoestrogens, and cyanogenic glucosides, in complete diets of lactating cows from 100 Austrian dairy farms. To achieve this, a validated multi-metabolite liquid chromatography/electrospray ionization–tandem mass spectrometric (LC/ESI–MS/MS) method was employed, detecting 155 of >800 tested metabolites. Additionally, the most influential dietary and geo-climatic factors related to the dietary mycotoxin contamination of Austrian dairy cattle were recognized. We evidenced that the diets of Austrian dairy cows presented ubiquitous contamination with mixtures of mycotoxins and phytoestrogens. Metabolites derived from Fusarium spp. presented the highest concentrations, were the most recurrent, and had the highest diversity among the detected fungal compounds. Zearalenone, deoxynivalenol, and fumonisin B1 were the most frequently occurring mycotoxins considered in the EU legislation, with detection frequencies >70%. Among the investigated dietary factors, inclusion of maize silage (MS) and straw in the diets was the most influential factor in contamination with Fusarium-derived and other fungal toxins and metabolites, and temperature was the most influential among the geo-climatic factors.
