Published: June 2023

Background

Peatlands contain about 500 Pg of carbon worldwide and play a dual role as both a carbon sink and an important methane (CH4) source, thereby potentially influencing climate change. However, systematic studies on peat properties, microorganisms, methanogenesis, and their interrelations in peatlands remain limited, especially in China. Therefore, the present study aims to investigate the physicochemical properties, archaeal community, and predominant methanogenesis pathways in three typical peatlands in China, namely Hani (H), Taishanmiao (T), and Ruokeba (R) peatlands, and quantitively determine their CH4 production potentials.

Results

These peatlands exhibited high water content (WC) and total carbon content (TC), as well as low pH values. In addition, R exhibited a lower dissolved organic carbon concentration (DOC), as well as higher total iron content (TFe) and pH values compared to those observed in T. There were also clear differences in the archaeal community between the three peatlands, especially in the deep peat layers. The average relative abundance of the total methanogens ranged from 10 to 12%, of which Methanosarcinales and Methanomicrobiales were the most abundant in peat samples (8%). In contrast, Methanobacteriales were mainly distributed in the upper peat layer (0–40 cm). Besides methanogens, Marine Benthic Group D/Deep-Sea Hydrothermal Vent Euryarchaeotic Group 1 (MBG–D/DHVEG–1), Nitrosotaleales, and several other orders of Bathyarchaeota also exhibited high relative abundances, especially in T. This finding might be due to the unique geological conditions, suggesting high archaeal diversity in peatlands. In addition, the highest and lowest CH4 production potentials were 2.38 and 0.22 μg g−1 d−1 in H and R, respectively. The distributions of the dominant methanogens were consistent with the respective methanogenesis pathways in the three peatlands. The pH, DOC, and WC were strongly correlated with CH4 production potentials. However, no relationship was found between CH4 production potential and methanogens, suggesting that CH4 production in peatlands may not be controlled by the relative abundance of methanogens.

Conclusions

The results of the present study provide further insights into CH4 production in peatlands in China, highlighting the importance of the archaeal community and peat physicochemical properties for studies on methanogenesis in distinct types of peatlands.

Published: June 2023

Background

The Hyperhidrosis Quality of Life Index (HidroQoL ©) is a well-developed and validated patient-reported outcome measure assessing the quality-of-life impacts in hyperhidrosis with 18 items. Our aim was to extend the already existing validity evidence for the HidroQoL, especially in relation to structural validity. Especially Rasch analysis has not been applied to the final 18-item HidroQoL before.

Methods

Data from a phase III clinical trial were used. Confirmatory factor analysis was conducted to confirm the two a priori HidroQoL scales within classical test theory. Furthermore, the assumptions of the Rasch model (model fit, monotonicity, unidimensionality, local independence) and Differential Item Functioning (DIF) were assessed using item response theory.

Results

The sample included 529 patients with severe primary axillary hyperhidrosis. The two-factor structure could be confirmed by the confirmatory factor analysis (SRMR = 0.058). The item characteristic curves showed mainly optimally functioning response categories, indicating monotonicity. The overall fit to the Rasch model was adequate and unidimensionality for the HidroQoL overall scale could be confirmed, since the first factor had an eigenvalue of 2.244 and accounted for 18.7%. Local independence was below assumed thresholds (residual correlations ≤ 0.26). DIF analysis, controlling for age or gender, was critical for four and three items, respectively. However, this DIF could be explained.

Conclusion

Using classical test theory and item response theory/Rasch analyses, this study provided further evidence for the structural validity of the HidroQoL. This study confirmed several specific (measurement) properties of the HidroQoL questionnaire in patients with physician-confirmed severe primary axillary hyperhidrosis: the HidroQoL is a unidimensional scale allowing the summation of scores to generate a single score, and simultaneously it has a dual structure, also allowing the calculation of separate domain scores for daily activities and psychosocial impacts. With this study, we provided new evidence of the structural validity of the HidroQoL in the context of a clinical trial.

Trial registration The study was registered (ClinicalTrials.gov identifier: NCT03658616, 05 September 2018, https://clinicaltrials.gov/ct2/show/NCT03658616?term=NCT03658616&draw=2&rank=1).

Published: June 2023

In the present work, a comparative study of analytical methods for the simultaneous and quantitative determination of trivalent and hexavalent chromium is presented. For the analysis by ion chromatography-inductively coupled plasma-mass spectrometry, two different columns were tested, as well as different mobile phases and different pH of the samples. The optimized analytical method permitted the separation of Cr(III) and Cr(VI) using 75 mmol/L NH4NO3 pH 3 as chromatographic eluent. The method was validated and applied to real samples, allowing the determination of both species simultaneously, even when there is a huge difference of concentration between Cr(III) and Cr(VI). Limit of detection and limit of quantification for Cr(III) were found to be 0.016 and 0.054 $$\upmu$$
μ
g/L (0.3 and 1.1 $$\upmu$$
μ
g/kg), respectively, and for Cr(VI) 0.13 and 0.43 $$\upmu$$
μ
g/L (7 and 22 $$\upmu$$
μ
g/kg), respectively. Possible species interconversions were monitored through the use of chromium isotopic standards, which confirmed that the optimized methodology preserves chromium speciation during extraction and analysis. Fourier-transform ion cyclotron resonance-mass spectrometry permitted the structure elucidation of the complex formed during ethylenediaminetetraacetic acid extraction.

Published: June 2023

Background

Metastases to the bones are a frequent location of metastasis in advanced breast cancer and are responsible for substantial morbidity and healthcare expenses. Imaging has been crucial in directing patient therapy for decades, contributing to the staging and response evaluation of the skeleton. This research aimed to assess the diagnostic value of whole-body magnetic resonance imaging with diffusion-weighted imaging added to radionuclide bone scans for early diagnosis of bone metastases in breast cancer patients.

Results

The study was a prospective observational cohort study performed on 20 patients with breast cancer and suspected bone metastases. The patients were evaluated first by obtaining a detailed personal history. Laboratory tests, including CBC, liver, and kidney function tests were assessed. All patients were examined by diffusion-weighted whole-body MRI (DWIBS; diffusion-weighted imaging with background body signal suppression) images and bone scintigraphy after intravenous injection of 20 mci of technetium-99m (99mTc) methylene diphosphonate using a dual head gamma camera. The total number of lesions detected by bone scan was 74, and 75 lesions were seen by DWIBS. Twenty-four lesions were missed by bone scan and detected by DWIBS. Fourteen lesions were detected by bone scan and found free by DWIBS examination in the spine and pelvic bones.

Conclusions

Whole body DWIBS seems to be a promising method of imaging in detecting bone metastases from breast cancer that could be used complementary to the traditional bone scan for more accurate diagnosis and staging of the tumor, helping to determine the most appropriate protocol of management.

Authors: Farag Eman Abas , Filobbos Soheir Assaad , Afifi Noha Mohammed , Mahmoud Shimaa Tarek , Alghandour Sarah Mohammed
Published: June 2023

Background

Adult-onset hypothyroidism has a deleterious effect on hippocampal cognitive and memory functions. This study was performed to evaluate the possible therapeutic effect of thyroxine on hippocampus degeneration in an adult male rat model of carbimazole-induced hypothyroidism and the potentiality of spontaneous recovery. Thirty-two adult male albino rats were divided equally into four groups, as follows: I (control group), II (hypothyroidism group) received carbimazole (20 mg/kg) orally once daily for 4 weeks; III (recovery group) rats were managed as in group II, then left untreated for an additional 4 weeks to assess spontaneous recovery; and IV (thyroxine-treated group): hypothyroidism was induced as in group II, then rats received levothyroxine (20 µg/kg/day) orally for 4 weeks. Rats and their corresponding controls were sacrificed after 4 weeks in group II and after 8 weeks in groups III and IV. The levels of T3, T4, and TSH were measured. Hematoxylin and Eosin staining of thyroid and hippocampal sections was performed. Additionally, toluidine blue staining and immunohistochemical staining for PCNA, GFAP, and synaptophysin were applied to hippocampus sections. Both morphometric measurements and statistical analysis were performed.

Results

Comparison of thyroxine-treated group with hypothyroidism and recovery groups revealed a significant reduction in TSH  level and an increase in T3 and T4 levels, as well as improved histological architecture in both the thyroid and hippocampal sections. Hippocampal sections revealed a significant decrease in the mean area percent of GFAP, a significant increase in the mean number of PCNA-positive cells in the subgranular zone (SGZ); a niche for the adult neural stem cells (NSCs) in the hippocampus; and a significant increase in the mean area percent as well as the mean optical density of synaptophysin.

Conclusion

Hippocampal degeneration is induced by hypothyroidism and can be restored by thyroxine replacement therapy, probably through neuronal cell preservation, synaptogenesis, and stimulation of neurogenesis in SGZ. On the other hand, spontaneous recovery from this degeneration was inadequate.
Equilibrium, kinetics, and thermodynamics of batch adsorption of Mn(II) ions on blast furnace slag (BFS) and kaolin (KGA)
Authors: Chouchane Toufik , Boukari Atmen. , Khireddine Ouahida , Chibani Sana , Chouchane Sabiha
Published: June 2023

This article describes the discontinuous adsorption of Mn(II) on kaolin from Guelma, Algeria (KGA), and blast furnace slag from Sider, Algeria (BFS), under the effect of various parameters, namely the contact time, the stirring speed, the pH of the medium, the solution temperature, the adsorbent dosage, the solid particle size, and the initial concentration. Also studied were the models of adsorption, namely the isotherms of adsorption, the kinetics of adsorption, and the thermodynamic study of Mn on the examined adsorbents. Characterization tests have indicated that kaolin consists essentially of hydrated aluminum silicate. The BFS is mainly composed of silicates, aluminates, lime, and magnesium oxide. The specific surface areas of kaolin and BFS calculated using the BET were defined at 134.2 and 238.6m2/g. The adsorption rate of Mn(II) on KGA and BFS is better after 50 and 60 min of contact at Vag: 150 rpm; pH: 5.2; Øs: 100 μm; T: 20 °C; Ms: 1 g, respectively. Maximum adsorption capacities are 36.76 mg/g (KGA) and 59.88 mg/g (BFS). Examination of the adsorption isotherms revealed that the Langmuir model is more appropriate to the experimental data (R2 = 0.99). The values of the Freundlich (n), Langmuir (RL), and Temkin (bt) parameters indicate that the adsorption is favorable. The kinetic examination demonstrated that the pseudo-second-order kinetic model is more adopted for the adsorption of Mn(II) on KGA and BFS (R2 = 0.99). Furthermore, the transfer of Mn(II) from the solution to the surfaces of the investigated adsorbents is controlled by external and internal diffusion. The thermodynamic study brought to light that the adsorption processes carried out were spontaneous, exothermic, and less entropic. This work showed that KGA and BFS can be used as low-cost adsorbents for the removal of Mn(II) ions in aqueous media, and BFS has higher affinities for manganese ion adsorption.

Published: June 2023

PURPOSE

Remote symptom monitoring (RSM) using electronic patient-reported outcomes enables patients with cancer to communicate symptoms between in-person visits. A better understanding of key RSM implementation outcomes is crucial to optimize efficiency and guide implementation efforts. This analysis evaluated the association between the severity of patient-reported symptom alerts and time to response by the health care team.

METHODS

This secondary analysis included women with stage I-IV breast cancer who received care at a large academic medical center in the Southeastern United States (October 2020-September 2022). Symptom surveys with at least one severe symptom alert were categorized as severe. Response time was categorized as optimal if the alert was closed by a health care team member within 48 hours. Odds ratios (ORs), predicted probabilities, and 95% CIs were estimated using a patient-nested logistic regression model.

RESULTS

Of 178 patients with breast cancer included in this analysis, 63% of patients identified as White and 85% of patients had a stage I-III or early-stage cancer. The median age at diagnosis was 55 years (IQR, 42-65). Of 1,087 surveys included, 36% reported at least one severe symptom alert and 77% had an optimal response time by the health care team. When compared with surveys that had no severe symptom alerts, surveys with at least one severe symptom alert had similar odds of having an optimal response time (OR, 0.97; 95% CI, 0.68 to 1.38). The results were similar when stratified by cancer stage.

CONCLUSION

Response times to symptom alerts were similar for alerts with at least one severe symptom compared with alerts with no severe symptoms. This suggests that alert management is being incorporated into routine workflows and not prioritized based on disease or symptom alert severity.

Published: June 2023

PURPOSE

Early integration of palliative care (PC) with standard oncology care is driving the development of innovative PC delivery models.

METHODS

This was a single-institution retrospective study of outpatient PC before and after the opening of an embedded thoracic oncology-palliative clinic at The Ohio State University. Patients included in the preintervention (October 2017-July 2018) and postintervention (October 2018-July 2019) cohorts had a diagnosis of any non–small-cell lung cancer (stages I-IV) or small-cell lung cancer (limited or extensive stage) and were newly established in the thoracic medical oncology clinic during the study time periods. All patients in the preintervention cohort had access to outpatient PC through a freestanding clinic, while the postintervention cohort had access to both freestanding and embedded clinics. Using time-to-event analyses, we evaluated differences in time intervals from first medical oncology visit to PC referral and first PC visit between cohorts.

RESULTS

The majority of patients in both cohorts had metastatic disease at diagnosis. In the postintervention cohort, 20.9% of patients were referred to outpatient PC compared with 9.2% in the preintervention cohort ( P < .01). PC referrals for patients outside of Franklin and adjacent counties increased from 4.0% to 14.2% after opening the embedded clinic ( P < .01). Completion percentages of PC referrals increased from 57.6% to 76.0% in the preintervention versus postintervention cohorts ( P = .048). Median time from palliative referral order to first PC visit decreased from 29 to 20 days ( P = .047). Similarly, median time from the first oncology visit to PC referral completion decreased from 103 to 41 days ( P = .08).

CONCLUSION

Implementation of an embedded PC model was associated with increased access to early PC among patients with thoracic malignancies.
Introduction: Thirty Years after Cultural Capital
Authors: Emre Merve , Sider Justin A.
Published: June 2023

This essay considers the status of John Guillory's Cultural Capital thirty years after its publication. Responding to an ongoing crisis in the humanities (which seems never to have passed) and to the “canon wars” of literary studies in the 1980s and 1990s, Cultural Capital refocused the debate about literary canons and aesthetic value away from contests of judgment in order to describe the social and institutional contexts of canon formation. What emerges from Guillory's Bourdieusian framework is a brilliant account not only of the process of canon formation but also of the professional anxieties that attend arguments about canonicity and representation. The essay explores the structure of Guillory's argument and considers why this work has been largely absent in recent debates about the state of the profession and the discipline of literary studies. The essay then introduces each contribution to this special issue, which seeks to bring Guillory's theory of canon formation back into contemporary debates about the future of literary studies, the politics of cultural representation, and the state of the humanities in crisis.
Elegizing Cultural Capital
Authors: During Simon
Published: June 2023

This article considers the legacy and value of John Guillory's literary sociology in providing a rationale for literary studies today. Bringing the work of Pierre Bourdieu to bear on the canon wars of the 1980s and 1990s, Guillory laid bare the mechanisms of canon formation within the institution of the school. While the influence of his argument is still perceptible in scholarly treatments of literary institutions, though, his more affirmative case for the general extension of literary appreciation and aesthetic judgment has gone unheeded. This is because Cultural Capital is not really interested in literature itself but in literature and literary education's functions and effects. Turning to Thomas Gray's “Elegy Written in a Country Churchyard,” this essay offers a literary and historical interpretation that contests Guillory's reading of the poem as an allegory of canon formation. It then finds in Stendhal's The Red and the Black an alternative allegory of the fate of the canon in a democratic society and argues finally for the continued value in teaching the canon to those engaged by it.

A protocol for cloning, expression, and purification of Lysine exporter (LysE) gene of Mycobacterium tuberculosis
Authors: Upadhyay Shilpa , Dhok Archana , Agarkar Vinod , Kashikar Supriya , Quazi Zahiruddin Syed
Published: June 2023

Background: Tuberculosis (TB) is among the deadliest diseases and a significant cause of illness across the globe. Several studies on mycobacterial proteins, such as proteases and transporters that are essential for survival and pathogenesis have aimed to develop an efficient anti-tubercular agent. In mycobacterium, lysine exporter (LysE) is an amino acid transporter and a probable target for an anti-tubercular agent as it is responsible for bacterial growth inhibition and is also absent in the widely used Bacillus Calmette-Guérin (BCG) vaccine.

Methods: Some studies have purified LysE using different protocols. This study describes a protocol for purifying different constructs of LysE, focusing on its hydrophobic region using immobilized metal affinity chromatography (IMAC) after expressing LysE gene in a bacterial expression system. pET vector (pET28a) is used as an expression vector. Amplied LysE gene is ligated with the pET28a vector, and the resultant plasmid is then transformed into E. coli cells. The vector has a histidine tag that makes the purification process convenient. After IMAC, the samples will be subjected to size-exclusion chromatography for further purification.

Results: Cloning and amplification findings will be analyzed using 1% agarose gel, and protein expression and purification outcomes will be examined using sodium dodecyl-sulfate polyacrylamide gel electrophoresis (SDS-PAGE). Domain-specific constructs of LysE can be further analyzed as an anti-tubercular agent.

Conclusions: Despite being a potential anti-tubercular target, research is quite limited on this protein. Therefore, we aim to purify LysE protein for further analysis. Similar protocols have already been implemented to purify several other bacterial proteins with >95% purity.
The role of salivary orosomucoid 1 as an early diagnostic and prognostic biomarker of hepatocellular carcinoma related to Hepatitis B: A systematic review
Authors: Limijadi Edward Kurnia Setiawan , Ar Ardiyana , Rahmawati Nurul Azizah Dian , Sudiasa I Nyoman Sebastian , Tjandra Kevin Christian
Published: June 2023

Background: Salivary orosomucoid 1 (ORM1) is highly increased in hepatocellular carcinoma related to hepatitis B. Thus, this systematic review aimed to investigate the diagnostic and prognostic value of salivary orosomucoid 1 (ORM1) in patients with that mentioned disease.

Methods: The sources included were original articles published from 2013 until 2023 (last date searched, January 2023) from 4 databases (ProQuest, Google Scholar, Springer, and ScienceDirect). The inclusion criteria were original research articles (observational cohort or diagnostic studies). Other article reviews, meta-analyses, non-comparative research, and in silico, in vitro and in vivo studies, technical reports, editor responses, conference abstracts, non-English, non-full-text, and irrelevant articles that were not related to either salivary ORM1, or hepatocellular carcinoma, hepatitis B, or kidney failure were excluded. Then, the ROBINS-I taken was used to assess bias. The result was constructed with PICOS criteria within the table created in the Google spreadsheet. This systematic review followed the PRISMA guidelines.

Results: Five diagnostic studies with 533 samples conducted in China and Japan. Limited original studies with homogenous PICO were a limitation, but the evidence output of this study can still be well presented. Salivary ORM1 may be useful to detect early cancer diagnosis as rapidly increased levels of ORM1 can be observed in the early stages of HCC (four times higher than usual) and the biomarker has a sensitivity of 81.67% and a specificity of 77.5%. This biomarker can detect the prognosis of individuals with the disease with or without chemotherapy. It is because level of salivary ORM1 related to liver damage, the higher the level of ORM1, the more liver damage occurs which leads to a poorer prognosis.

Conclusions: Salivary ORM1 is a potential early diagnostic biomarker of HCC related to hepatitis B and a biomarker of the disease prognosis.

Mapping the international ecosystem of national health data spaces. A scoping review protocol
Authors: Maxwell Lauren
Published: June 2023

Background: The reuse of participant-level health data by public health and surveillance institutions, hospitals, doctors, and patients is an emerging priority for a number of national governments. Technical and semantic interoperability of health data ecosystems is important for detecting and responding to global health challenges, including emerging infectious diseases, antimicrobial resistance, and vaccine-preventable illnesses. In this scoping review, we will identify and describe health data ecosystems, spaces, clouds, and commons, national-level mechanisms for enabling the reuse of participant-level health data.

Methods and analysis: We will apply the Arskey and O’Malley scoping review approach to describe governance, content, and semantic and technical interoperability of data and metadata in national health data ecosystems. We selected a scoping rather than a systematic review methodology to provide a high-level analysis of the current state of health data ecosystems’ implementation of the FAIR principles for data resources. The systematic search strategy was pilot tested and tailored for Ovid(Medline), CINAHL, and Web of Science. We will also conduct web scraping and consult stakeholders to identify additional health data ecosystems. Two reviewers will conduct the title-abstract and full-text screening and data charting independently. Discrepancies will be resolved by consensus, and results will be summarized in narrative form.

Ethics and dissemination: Ethical approval is not required for this scoping review of published studies and grey literature. The scoping review protocol was registered prior to initiating the search strategy. Study results will be submitted for publication in an Open Access journal.

Published: June 2023

The well-known fact is that parks play a significant role in sustaining the urban environment. Megacities like Karachi are developing rapidly with a simultaneous increase in the city area, putting immense pressure on open green spaces. The widespread built-up development is replacing the previously existing vegetative cover. The lack of green spaces is the main concern, and this problem will only worsen due to overpopulation associated with the rapid growth of cities. The lack of evidence-based planning contributes to the unbalanced spatial distribution of parks in quantity and quality. The present research aimed to compare and find out the quality and status of parks such as park areas under encroachment and temporal changes in the vegetative cover of parks in the predominantly low to middle-income residential areas of New Karachi and North Karachi Towns of Karachi metropolitan. Geospatial techniques have been used for mapping, assessments, and analyses. Results indicate that boundary walls are a good solution to stop or reduce park encroachments as correlation indicates the parks with boundary walls have a significantly lower percentage of encroachment in 2022. The existing work indicated that the number of trees has increased in most parks in both towns in 2022. The overall correlation results indicate that factors affecting park quality positively have a positive association with other positively affecting factors and a negative association with factors that affect park quality negatively. There is a dire need to implement better planning strategies to enhance the quality of existing parks and construct new parks in the study area.
Ocena jakości szafranu (Crocus sativus L.) z wykorzystaniem metod spektroskopowych
Authors: Stolarek Karolina , Uram-Dudek Angelika , Wawer Iwona , Paradowska Katarzyna
Published: June 2023

Szafran (Croccus sativus L.) to wyjątkowa roślina, ceniona na całym świecie. Uznawana za jedną z najdroższych i najszlachetniejszych przypraw. Właściwości szafranu znali już starożytni, którzy nie tylko dodawali szafran do dań i napitków, barwili nim tkaniny, ale także stosowali go w celach prozdrowotnych. Roślina ta jest doskonałym środ-kiem wspomagającym trawienie, poprawiającym nastrój i apetyt. W wielu badaniach naukowych wykazano również jej właściwości antydepresyjne, przeciwdrgawkowe, przeciwnowotworowe, antybakteryjne oraz antyoksydacyjne. Ze względu na szerokie zastosowanie tego materiału roślinnego, różne pochodzenie czy czas przechowywania, ważna jest weryfikacja surowca pod względem składu oraz właściwości. Stąd też ważne jest poszukiwanie szybkich, nieniszczących metod analitycznych, pozwalających na kontrolę surowca. W artykule przedstawiono analizę jakościową głównych bioaktywnych związków szafranu: krocyny, pikrokrocyny oraz safranalu z wykorzy-staniem trzech technik spektroskopowych: spektroskopii UV-Vis, magnetycznego rezonansu jądrowego w stanie stałym (1H MAS i 13C CPMAS NMR) oraz paramagnetycznego rezonansu jądrowego (EPR). Materiał poddano również analizie właściwości antyoksydacyjnych szafranu z wykorzystaniem testu zmiatania wolnego rodnika DPPH. Test przeprowadzono na materiale świeżym i pookresie starzenia materiału –(promieniowanie UV). Na podstawie otrzymanych wyników stwierdzono, że do przeprowadzenia analizy jakościowej badanych próbek wskazane jest zastosowanie kilku metod analitycznych w celu uzyskania pełnego obrazu. Widma 1H MAS NMR zarejestrowane dla próbek w postaci proszku rozróżniają próbki na podstawie związków z mobilnymi łańcuchami alifatycznymi. Natomiast analiza widm 13C CPMAS NMR umożliwia odróżnienie próbek i identyfikacje głównych składników (pierścienie aromatyczne, cukry czy grupy karbonylowe). Wykorzystanie charakterystycznych pasm absorpcji dla głównych składników szafranu może stanowić podstawę do określenia jakości badanego materiału roślinnego. Przeprowadzona analiza z zastosowaniem rodnika DPPH wykazała, iż szafran posiada wysokie właściwości antyoksydacyjne, działanie promieni UV powoduje ich zmniejszenie średnio o 50%.

Published: June 2023

Celem niniejszej pracy było określenie wpływu terminu zakładania plantacji na plon i jakość nasion babki płesznik. Zastosowano dwa terminy zakładania plantacji: siew wiosenny nasion (III dekada maja) oraz siew późnowiosenny (III dekada czerwca). Nasiona wysiewano w ilości 3 kg·ha-1. Po zbiorze nasion określono: plon nasion z 1m-2, masę 1000 nasion i ich zdolność kiełkowania. W nasionach określono zawartość związków śluzowych, kwasów polifenolowych. Siew wiosenny nasion okazał się korzystniejszy pod względem uzyskanego plonu oraz wartości siewnej nasion. Późnowiosenny termin wysiewu nasion okazał się lepszy pod względem uzyskanej masy 1000 nasion. Zawartość kwasów polifenolowych oraz śluzów w nasionach nie zależała istotnie od terminu wysiewu nasion

Introduction: Flavonoids are bioactive chemical compounds crucial for the functioning of plant organisms. Recently, they have been intensively studied in search of their potential application in medicine. One of the most popular fields in that regard is oncology. Digestive tract cancers are still a challenge for contemporary medicine. Our diet seems to have a direct impact on the etiology of colorectal, gastric, and esophageal cancers. The relationship between the consumption of flavonoids, their specific fractions, and digestive tract cancer morbidity is nowadays frequently investigated.Purpose: This review article aims to discuss the most recent scientific reports and summarize the current state of knowledge, considering the role of flavonoids in digestive tract cancer prevention.Materials and methods: Our work is based on articles accessed through medical information databases (Google Scholar, PubMed, CrossRef), various scientific books, and official NFZ and WHO-certified sites.Results: Total flavonoid intake lowers gastric and esophageal cancer morbidity. A high amount of dietary catechins prevents the growth of gastric and colorectal cancer. Increased consumption of anthocyanidins, flavones, and flavanones decreases esophageal cancer morbidity. Isoflavones, procyanidines, anthocyanidins, flaonols, and flavones severely decrease the chance of developing colorectal cancer.Conclusions: Flavonoids can play an important role in digestive tract cancer prevention. They suppress the growth of colorectal, gastric, and esophageal cancers. Nevertheless, new, high-quality studies are needed in order to compile adequate procedures and bring new, potential drugs to the market.

A Unified Logical Framework for Reasoning about Deontic Properties of Actions and States
Authors: Kulicki Piotr , Trypuz Robert , Craven Robert , Sergot Marek J.
Published: June 2023

This paper studies some normative relations that hold between actions, their preconditions and their effects, with particular attention to connecting what are often called ‘ought to be’ norms with ‘ought to do’ norms. We use a formal model based on a form of transition system called a ‘coloured labelled transition system’ (coloured LTS) introduced in a series of papers by Sergot and Craven. Those works have variously presented a formalism (an ‘action language’) nC+ for defining and computing with a (coloured) LTS, and another, separate formalism, a modal language interpreted on a (coloured) LTS used to express its properties. We consolidate these two strands. Instead of specifying the obligatory and prohibited states and transitions as part of the construction of a coloured LTS as in nC+, we represent norms in the modal language and use those to construct a coloured LTS from a given regular (uncoloured) one. We also show how connections between norms on states and norms on transitions previously treated as fixed constraints of a coloured LTS can instead be defined within the modal language used for representing norms.

Logical Constants and the Sorites Paradox
Authors: Garrett Zack
Published: June 2023

Logical form is thought to be discovered by keeping fixed the logical constants and allowing the non-logical content in the sentence to vary. The problem of logical constants is the problem of defining what counts as a logical constant. In this paper, I will argue that the concept ’logical constant’ is vague. I demonstrate the vagueness of logical constancy by providing a sorites argument, thereby showing the sorites-susceptibility of the concept. Many prior papers in the literature on logical constants hint at this vagueness, but do not explore how theories of vagueness apply to logical constants. In the second half of this paper, I do just this. I consider approaches to logical constants that resemble nihilism about vagueness and more recent theories that relativize truth to precisifications. Finally, I argue that approaches that accept the potential indeterminate status of putative logical constants are preferable to nihilism or relativism about logical constancy.
Nonrobust Strong Knapsack Cuts for Capacitated Location Routing and Related Problems
Authors: Liguori Pedro Henrique , Mahjoub A. Ridha , Marques Guillaume , Sadykov Ruslan , Uchoa Eduardo
Published: June 2023

“Nonrobust Strong Knapsack Cuts for Capacitated Location Routing and Related Problems,” by Liguori et al., presents a novel BCP algorithm for the CLRP and for other problems that share a nested knapsack structure. It outperforms existing exact algorithms in the literature, making it a powerful tool for solving instances with a large number of depot locations. A key methodological contribution is the introduction of RLKCs, a family of nonrobust cuts derived from the “outer” knapsack constraints. These cuts are strong in the sense that they contain all facets of the master knapsack polytope, dominating the cover cuts by Dabia et al. (2019) . By exploring their monotonicity and superadditivity properties, it is possible to adapt the labeling algorithm for handling RLKCs efficiently. The overall positive impact of RLKCs on the BCP performance varies depending on the problem and instance characteristics, but they have proven particularly effective for CLRP instances with tight depot capacities, making the final BCP algorithm more reliable.
