Maximizing the valorization potential of lignin through optimization of the Soda pulping conditions
No full textThe valorization potential of lignin is strongly dependent on the yield that can be obtained during the pulping process as well as its chemical structure. Both of these are determined by factors such as the biomass type, the selected extraction strategy and the employed conditions. Within this study, Miscanthus x giganteus biomass was subjected to systematically varying Soda pulping conditions, i.e., temperature (100 °C – 180 °C), OH– concentration (0.158 mol/L – 1.000 mol/L) and time (60 min – 360 min). These pulping conditions can be combined into a single factor, reflecting the processing severity, which in this work varied from approximately 1 to 5. The resulting black liquor, precipitated lignin, lignin stock solution (i.e., lignin dissolved in the solvent used in the subsequent depolymerization step) and product pool after mild reductive catalytic depolymerization (200 °C, 10 bar H2 initial, 4 h) were thoroughly characterized using a plethora of analysis techniques. Increasing the severity factor of the pulping was found to result in an enhancement of the delignification degree from 25.3 ± 2.6 % to 95.4 ± 9.9 %. However, beyond a severity factor of 3, fragmentation of native ether linkages and condensation reactions start to cause unfavourable changes in the chemical structure of the lignin and depolymerization product pool. Furthermore, these reactions significantly reduce the total mass yield from biomass to depolymerization product pool. An Adaboost model with quadratic base estimator was trained against the experimental data, and subsequently used to optimize the pulping conditions, aiming at a maximum total mass yield with minimal fragmentation and, hence, condensation, of the lignin. The optimum was experimentally validated, which resulted in a lignin with high β-O-4 content (42.7 ± 2.8 linkages per 100 aromatic units) and a total mass yield of 30.9 ± 3.4 wt% and a pulp with a residual lignin content of 8.25 ± 0.94 wt%.The valorization potential of lignin is strongly dependent on the yield that can be obtained during the pulping process as well as its chemical structure.

Bioactive phenolic compounds in red algae (Rhodophyta) : ecological variation and their antioxidant potential
No full textSeaweeds have garnered significant attention in recent years due to their chemical and bioactive properties, which hold promise for discovering new molecules with valuable applications for humanity. Among their metabolites, phenolic compounds stand out for their structural diversity and high abundance in seaweeds. The most extensively studied class of seaweed polyphenols is phlorotannins, uniquely synthesized by brown seaweeds. However, other polyphenolic compounds such as bromophenols, flavonoids, phenolic terpenoids, and mycosporine-like amino acids add to their chemical complexity. These identified and characterized compounds exhibit a wide range of bioactivities, suggesting potential applications across various industrial sectors. Green and red algae have been described to contain lower concentrations of phenolic compounds than brown algae, and by consequence have received considerably less attention. Moreover, most studies reporting phenolic content use the colorimetric Folin-Ciocalteu assay, which is incapable of discriminating the diversity of phenolic compounds known so far. Therefore, in this study, we aimed to characterize and quantify phenolic compounds in four cultivated red algae (Palmaria palmata, Porphyra umbilicalis, Gracilaria gracilis and Acrochaetium secundatum) using liquid chromatography-mass spectrometry (LC-MS). We evaluated different solvents to optimize the extraction of the phenolic components in the seaweed. Additionally, we investigated variation in the antioxidant activity of the obtained extracts.Seaweeds have garnered significant attention in recent years due to their chemical and bioactive properties, which hold promise for discovering new molecules with valuable applications for humanity.

Towards new futures for archaeological data production : challenging archaeonormativity through storytelling
No full textArchaeologists create vast amounts of specialized data, which are often difficult to access, maintain, and reuse, even for practitioners themselves. In this article, we explore the implication of professional practices of data production in fueling archaeonormativity-i.e., the naturalization of behaviors and structures in archaeology that strip it of affect and meaning and that deny human (and non-human) agency and equity. We contend that storytelling with archaeological data-making, grounded in a narrative hermeneutic model, has promise for subverting the current archaeonormative establishment. Via experimentation on the cross-European Transforming Data Reuse in Archaeology project, we discuss the challenges of intervening in excavation and post-excavation activities through storytelling, from siloing of results to epistemic anxieties to destabilization of trust, leadership, and institutional authority. Nurturing creative, story-critical risk-taking in the course of archaeological data production may enable archaeologists to improve their own working contexts whilst also (re)distributing power inside and outside the profession.Archaeologists create vast amounts of specialized data, which are often difficult to access, maintain, and reuse, even for practitioners themselves.

The association between physiological markers of stress response systems and experimentally induced pain assessments in chronic primary pain: A systematic review and meta-analysis
No full textBackground and aims: Besides psychological distress, (dys)functioning of stress systems, i.e. the autonomic nervous system (ANS) and hypothalamuspituitary-adrenal (HPA-)axis, has been implicated in pain. However, the exact interplay between (re)activity of stress and pain systems in chronic painremains unclear. This study will synthesize the evidence regarding their interactions in chronic pain.Methods: A systematic review and meta-analysis was pre-registered on PROSPERO (CRD42024495934). Six databases were searched to identify studiesexamining at least one physiological stress marker of ANS or HPA-axis reflecting basal levels, reactivity and/or recovery, and one experimental outcomemeasure of pain in adults with chronic primary pain. Risk of bias (RoB) was evaluated with the Newcastle-Ottawa Scale, and certainty of evidence (CoE) withGRADE.Results: Forty-six studies (3 cross-sectional, 43 case-control; n=2407) were included and scored averagely 9/12 (5-11) on RoB. Overall CoE was (very) low.At baseline, qualitative analyses showed significant correlations between lower mean arterial pressure and higher pain sensitivity in patients with chronicpain which was confirmed in the meta-analyses (r=.301-.373, p=.013-.033). Furthermore, meta-analyses showed that higher cortisol levels were associatedwith lower pressure pain thresholds (PPTs) at baseline. Higher heart rate was associated with lower PPTs, and lower high-frequency heart rate variabilitywith lower cold pain tolerance when stress markers were measured both during and after a stressor (r=.218-.429, p=.009-.050).Conclusions: Dysregulation of baroreceptor and HPA-axis functioning seems to be related to higher pain sensitivity at baseline, and autonomic dysfunctionmight be related to higher pain sensitivity under acute stress in patients. However, the evidence is low and limited.Background and aims: Besides psychological distress, (dys)functioning of stress systems, i.e. the autonomic nervous system (ANS) and hypothalamuspituitary-adrenal (HPA-)axis, has been implicated in pain.

Experimental warming and permafrost thaw decrease soil nematode abundance in northern palsa peatlands
No full textGlobal warming is profoundly impacting northern ecosystems, particularly those underlain by permafrost. Permafrost-affected peat plateaus, called palsa peatlands, consist of mounds with peat and mineral soil covering ice lenses. When permafrost thaws, palsas can collapse and undergo significant hydrological changes to form wet mires. This affects the physical structure of the soil and as a result, the communities of soil-dwelling organisms, such as nematodes. Although the role of nematodes in carbon cycling is not fully understood, they can influence greenhouse gas emissions through interactions with plants and microbes. This study examined the effects of palsa degradation and experimental warming on nematode feeding guilds (bacterivores, fungivores, root feeders, and omni-carnivores) in northern Norway, where permafrost is rapidly thawing. Our findings showed that intact, vegetated palsas supported higher abundances of all nematode feeding guilds. With warming, bacterivorous and omni-carnivorous nematodes were negatively affected. Additionally, we observed a shift in dominance of bacterivores to fungivores over the summer, suggesting a temporal shift in the predominant decomposition pathway. No direct relationships were found between changes in any of the guild abundances and measured CO2 and CH4 fluxes. This study highlights the fact that expected warming and the degradation of palsas may have varied but had predominantly negative impacts on different nematode feeding guilds. Given the role of soil nematodes in nutrient cycling and other soil processes, their decline under warmer conditions could have ecosystem-level consequences in these palsa peatlands.Global warming is profoundly impacting northern ecosystems, particularly those underlain by permafrost.

Pyridine-covalent triazine framework (py-CTF) as a metal-free catalyst for effective toluene abatement in post-plasma catalytic systems
No full textIn this study, we explore, for the first time, the use of a new pyridine-covalent triazine framework (py-CTF), containing both nitrogen and oxygen, as a metal-free catalyst in a post-plasma catalytic (PPC) system for abatement of toluene, a common volatile organic compound (VOC). The PPC system was evaluated under varying specific energy densities (SEDs) from 100 to 400 J/L and catalyst temperatures ranging from room temperature to 200 degrees C. Our findings reveal that combining py-CTF with non-thermal plasma significantly enhanced toluene removal efficiency compared to both plasma alone and catalyst alone systems. A remarkable toluene removal efficiency of 97.2% and COx (CO + CO2) selectivity of 67.1% were achieved in the PPC system at an optimal catalyst temperature of 150 degrees C and an SED of 400 J/L, with minimized ozone production. In contrast, the plasma alone showed a removal efficiency of 54.8% and COx selectivity of 21.6% at the same SED, while the catalyst-alone reached 31.1% removal efficiency and 50.4% COx selectivity at the higher temperature of 400 degrees C. Notably, the energy yield (EY) improved from 4.1 g/kWh in plasma alone to 14.0 g/kWh in PPC at an SED of 100 J/L. Moreover, the py-CTF catalyst demonstrated excellent long-term stability, maintaining high efficiency and selectivity over extended operation times. Catalyst characterization before and after plasma treatment demonstrated minimal changes in physicochemical properties, confirming its durability. This study thus highlights the potential of py-CTF as a sustainable alternative to metal-based catalysts in plasma-catalytic VOC abatement.In this study, we explore, for the first time, the use of a new pyridine-covalent triazine framework (py-CTF), containing both nitrogen and oxygen, as a metal-free catalyst in a post-plasma catalytic (PPC) system for abatement of toluene, a common volatile organic compound (VOC).

E2FA is a major transcription factor controlling the mitotic cycle and the endocycle in nematode‐induced feeding sites
No full textPlant host cell-cycle hyperactivation is essential for nematode feeding site (NFS) ontogenesis, but the balanced mitotic and endoreplication cycles must occur for homeostasis. Alterations in core cell cycle gene expression are well known to disturb root-knot and cyst-NFS development. Herein, our investigation focused on the activity of E2FA and E2FB transcription factors in root-knot nematode-induced galls in Arabidopsis thaliana controlling both the mitotic and endocycles through the activation of S-phase cell cycle genes. The roles of the two plant E2F activators during cell cycle progression in galls were compared with syncytia induced by cyst nematodes. E2FA and E2FB transcripts were highly expressed in both galls and syncytia. Loss-of-function analysis revealed that the absence of E2FA and E2FB impaired feeding-site development, resulting in significantly reduced gall development and nematode reproduction. Transcript analysis of galls upon E2FA and E2FB loss-of-function compared with that of wild-type revealed differential expression of selected target genes operating during S phase. Although our results imply the functional interplay of E2FA and E2FB for gall development, we recognize that E2FA alone commands and sustains cell division as well as the endocycle in galls and syncytia, whereas E2FB is likely partaking in nematode-induced gall initiation.Plant host cell-cycle hyperactivation is essential for nematode feeding site (NFS) ontogenesis, but the balanced mitotic and endoreplication cycles must occur for homeostasis.

Assessment of human taeniasis and other intestinal parasites in Narok County, Kenya
No full textData are sparse on the epidemiological picture of Taenia saginata taeniasis in Kenya. Infections are underreported, and their persistence nonetheless negatively impacts the beef industry. Populations vulnerable to taeniasis in the developing world are commonly burdened with other intestinal parasites, ubiquitous in unsanitary environments. This study aimed to estimate the occurrence of human taeniasis in Narok County, Kenya, and screen for the presence of other intestinal parasitic infections. A community-based survey was conducted in five pastoral wards, and stool samples, mainly from adults, subjected to multiple diagnostic tests. One sample tested positive for Taenia spp. by coproantigen enzyme-linked immunosorbent assay (0.3%, 95% CI, 0-1.6, n = 360), and all samples tested negative on multiplex copro-polymerase chain reaction targeting the cytochrome c oxidase subunit 1 gene and copromicroscopy. Microscopy (n = 361) additionally identified Entamoeba histolytica/dispar/moshkovskii at a prevalence of 15.5% (95% CI, 12.1-19.6), Giardia spp. at 5.3% (95% CI, 3.4-8.1), Hymenolepis spp. at 1.1% (95% CI, 0.4-2.8), and hookworm at 0.3% (95% CI, 0-1.6). Grazing livestock near the homestead (< 2 km) and a formal education background were associated with a reduced likelihood of Giardia spp. infection (AOR 0.07, 95% CI 0-0.36, p = 0.011, and AOR 0.06, 95% CI 0.01-0.50, p = 0.014, respectively). Our findings suggest a very low prevalence of human taeniasis in the population. The occurrence of other pathogenic zoonotic intestinal parasites highlights a public health concern and calls for a One Health approach in the enhancement of hygiene initiatives.Data are sparse on the epidemiological picture of Taenia saginata taeniasis in Kenya.
