Omsorg i accelereret kræftudredning.
Authors: Aarhus Rikke 
Published: July 2024

Denne artikel tager sit afsæt i de forandringer i velfærdsstaten, der betyder at mere omsorgsarbejde flyttes over i familien med deraf følgende forventninger om, at pårørende yder omsorg for patienten i tilfælde af sygdom. Litteraturen belyser, at denne omsorg omfatter praktisk, emotionel og behandlingsmæssig støtte, men også at omsorgsrelationen kan være vanskelig. I artiklen viser jeg, hvordan ovennævnte forandringer og forventninger udfolder sig i accelererede kræftpakke-udredningsforløb ved at undersøge, hvordan omsorgsarbejde i form af pårørendeinddragelse forhandles i mødet mellem sundhedsprofessionelle og patienter.
Artiklen er baseret på et etnografisk feltstudie i udredningsdelen af tre kræftpakker, hvor jeg observerede og interviewede patienter, pårørende og sundhedsprofessionelle. Feltstudiet fandt sted i almen praksis, på hospitaler og i patienters hjem. Kræftpakkerne beskriver standardiserede og accelererede forløb for bl.a. udredning og behandling.
I artiklen viser jeg, at der i kræftudredningsforløb er en implicit forståelse af omsorg, hvor pårørende udpeges som centrale for et vellykket forløb. Dette skaber forestillinger om og forventninger til patienters mobilisering af pårørende samt til disses bidrag. Forventninger som patienter forhandler ud fra deres egen opfattelse af forbundethed og i forhold til eksempelvis målene om hurtig og tidlig diagnostik i det danske sundhedsvæsen. Mens patienten har indflydelse på, hvilke pårørende der involveres, så viser jeg, at systemet har koloniseret omsorgsrelationen. Med accelererede forløb er således opstået et behov for at genforhandle, hvad det betyder at være pårørende i tilfælde af sygdom.

The subject of the study is the coping strategies and protective mechanisms of 1st and 4th year students with different levels of adaptability. Successful adaptation of a student is an important condition for successful educational and cognitive activity. Based on this, the problem of studying the adaptation process and determining the factors that affect the success of this process among students is relevant. Significant and important factors influencing the adaptation process of students are coping strategies and the protective mechanism of personality. Students of 1st (30 people) and 4th year (29 people) were examined. Significant differences were obtained in the groups of highly, medium and low-adaptive 1st and 4th year students in terms of psychological defense parameters and coping strategies. The study was conducted using the following methods: the methodology for diagnosing the socio-psychological adaptation of K. Rogers and R. Diamond, the Plutchik – Kellerman – Conte questionnaire "Lifestyle Index", the questionnaire "Methods of coping behavior" by R. Lazarus. The scientific novelty of the study is related to the results obtained in the diagnosis of coping strategies and defense mechanisms of the 1st and 4th year students with different levels of adaptability. 1st and 4th year students with a high level of adaptation have similar mechanisms of psychological protection, namely: rationalization, compensation, as well as similar types of coping strategies: problem solving planning, self-control, taking responsibility. 1st and 4th year students with a low level of adaptation have differences in the mechanisms of psychological protection, namely: 1st year students have such types of psychological protection as: regression; coping strategy – escape- avoidance; 4th year students have types of psychological protection – denial; coping strategy – search for social support.

Leaf mustard (Brassica juncea L. Czern & Coss), an important vegetable crop, experiences pronounced adversity due to seasonal drought stress, particularly at the seed germination stage. Although there is partial comprehension of drought-responsive genes, the role of long non-coding RNAs (lncRNAs) in adjusting mustard’s drought stress response is largely unexplored. In this study, we showed that the drought-tolerant cultivar ‘Weiliang’ manifested a markedly lower base water potential (−1.073 MPa vs −0.437 MPa) and higher germination percentage (41.2% vs 0%) than the drought-susceptible cultivar ‘Shuidong’ under drought conditions. High throughput RNA sequencing techniques revealed a significant repertoire of lncRNAs from both cultivars during germination under drought stress, resulting in the identification of 2,087 differentially expressed lncRNAs (DELs) and their correspondingly linked 12,433 target genes. It was noted that 84 genes targeted by DEL exhibited enrichment in the photosynthesis pathway. Gene network construction showed that MSTRG.150397, a regulatory lncRNA, was inferred to potentially modulate key photosynthetic genes (Psb27, PetC, PetH, and PsbW), whilst MSTRG.107159 was indicated as an inhibitory regulator of six drought-responsive PIP genes. Further, weighted gene co-expression network analysis (WGCNA) corroborated the involvement of light intensity and stress response genes targeted by the identified DELs. The precision and regulatory impact of lncRNA were verified through qPCR. This study extends our knowledge of the regulatory mechanisms governing drought stress responses in mustard, which will help strategies to augment drought tolerance in this crop.

Published: July 2024

Biocontrol agents, including Cyanobacteria, Spirulina platensis and Nostoc calcicole, as well as Fulvic Acid and nano-chitosan were tested to control leaf rust of wheat under field conditions during 2021/2022 and 2022/2023 growing seasons. All biocontrol agents significantly reduced all parameters for disease severity i.e. coefficient of infection (CI), the average coefficient of infection (ACI) and the area under disease progress curve (AUDPC) compared to untreated control. The best treatments were nano-chitosan which recorded efficacy of 91.17% followed by S. platensis (90.2%) in the application of two sprays for disease control. All biocontrol agents significantly increased grain yield components of wheat. Applications of two sprays were more effective than one spray. From our research work it can be concluded that S. platensis, N. calcicole, Fulvic Acid and nano-chitosan can be used for controlling leaf rust disease as a safe alternative to chemical fungicides.

Aim: This study assess the prevalence of malnutrition and underweight among school boys in Ogbia LGA, Bayelsa state.
Methods: The was a cross sectional study consisting of 250 school boys within the ages of 5-10yrs selected randomly from five communities during school period. Data were obtained using weight scale balance calibrated in (kg), metre rule (m), muac tape (cm) and well-structured questionnaire. The weight for age, height for age, MUAC and BMI methods used in this study was in accordance with WHO, IAP classification.
Results: This study shows a significant difference (<0.05) between the weight, height and BMI of school boys in Ogbia, Oloibiri/Otuogidi when compared with Otuabagi/otuakeme. Muac mean value for the entire age 5-10yrs in Ogbia axis was 17cm compared with Otuabagi axis of 16cm with no significant p-value observed. Carbohydrate (56.8%) dietary food was mostly consumed regularly in comparison with carbohydrate/protein (32%), protein (8%) and vegetable/vitamins (3.2%) among the children. More so 78.4% of the study population have not been deworm for the past over 3months and above. However 21.6% of the study population are deworm within 3month intervals. This study further observe 41.6% among the children as underweight falling below the 1st percentile level with just 13.2% in the median green line zone having normal weight in both communities. However 15.2% are within the 97th percentile while 1.6% are above this zone. The weight for age regarding PEM classification shows 55.89% and 0.74% children suffering from severe and very severe malnutrition in Ogbia, Oloibiri/Otuogidi though 32.37% are PEM free compared with 66.68% normal children in Otuabagi/otuakeme, however 28.07% and 1.75% are suffering from severe and very severe cases of malnutrition in the just two mention communities above.
Conclusion: The combination of the entire percentages from the different communities considered in this study shows 1.2% and 43.2% prevalence rate of very severe and severe malnutrition compare with 48% PEM free among boys in Ogbalga while 44% and 16.8% are underweight and overweight/obese compared with 13.2% on the green median zone of normal weight for age. Intervention strategies that include appropriate children feeding with micronutrients should be implemented to reduce the burden of under nutrition in addition to effective regular deworming to help reduce the burden of weight deficit among children in the state.

Sesame (Sesamum indicum L.), an ancient oilseed crop, is cultivated in central and northern India under rainfed conditions during the kharif season. Despite its high oil and protein content, sesame cultivation area and production remain low due to various reasons. This study conducted at CCS HAU, Hisar, aimed to improve sesame yield through plant breeding by examining correlation and path analysis. This trial was conducted using augmented RCBD and data was recorded on traits including plant height(cm), primary branches plant-1, secondary branches plant-1, number of capsules plant-1, and seed yield plant-1. Genotypic correlations showed that seed yield plant-1 positively correlated with the number of capsules plant-1 (r = 0.854**), primary branches plant-1 (r = 0.602**), secondary branches plant-1 (r = 0.283*) and slightly negatively with plant height (r = -0.064). Path analysis indicated the number of capsules plant-1 had the highest direct effect on seed yield plant-1 (0.769) followed by primary branches plant-1. The study concludes that enhancing primary branches plant-1 and capsules plant-1 while managing plant height can significantly boost sesame yield.

O presente artigo tem por analise a correlação entre direito e literatura, à luz da obra Capitães da Areia, de Jorge Amado e da Teoria do Estrutural Funcionalismo de R. Merton e a subcultura delinquente de A. Cohen. Com esse intento, o referido estudo jurídico-literário do direito na literatura aborda o tratamento dado aos jovens em condições de vulnerabilidade perante a nossa sociedade brasileira, os quais, em decorrência de fatores sociais são direcionados a cometerem delitos, concomitantemente, entrando em conflito com a lei. De tal modo, por meio de pesquisa qualitativa com base em levantamento bibliográfico e dados estatísticos, pretende-se descrever o fenômeno jurídico, social e político que são absorvidos e replicados na sociedade e perceptíveis no romance, no qual o autor demonstra com maestria e sensibilidade a paralisação do Estado e as suas negligências em relação a vulnerabilidade de determinados indivíduos em uma sociedade desigual e injusta, em que pese, para essa parcela da sociedade a visibilidade revela-se, quase que exclusivamente, advinda do cometimento de delitos, em grade parte por e para a própria subsistência.

AbstractCommercial N2‐isobutyryl‐5′‐O‐(4,4′‐dimethoxytrityl)‐2′‐O‐(propargyl)guanosine is converted to its 3′‐O‐levulinyl ester in a yield of 91%. The reaction of commercial N2‐isobutyryl‐5′‐O‐(4,4′‐dimethoxytrityl)‐2′‐O‐tert‐butyldimethylsilyl‐3′‐O‐[(2‐cyanoethyl)‐N,N‐diisopropylaminophosphinyl]guanosine with N2‐isobutyryl‐2′‐O‐propargyl‐3′‐O‐(levulinyl)guanosine provides, after P(III) oxidation, 3′‐/5′‐deprotection, and purification, the 2′‐O‐propargylated guanylyl(3′‐5′)guanosine 2‐cyanoethyl phosphate triester in a yield of 88%. Phosphitylation of this dinucleoside phosphate triester with 2‐cyanoethyl tetraisopropylphosphordiamidite and 1H‐tetrazole, followed by an in situ intramolecular cyclization, gives the propargylated cyclic dinucleoside phosphate triester, which is isolated in a yield of 40% after P(III) oxidation and purification. Complete removal of the nucleobases, phosphates, and 2′‐O‐tert‐butyldimethylsilyl protecting groups leads to the desired propargylated c‐di‐GMP diester. Cycloaddition of a biotinylated azide with the propargylated c‐di‐GMP diester under click conditions provides the biotinylated c‐di‐GMP conjugate in an isolated yield of 62%. Replacement of the 6‐oxo function of N2‐isobutyryl‐5′‐O‐(4,4′‐dimethoxytrityl)‐3′‐O‐levulinyl‐2′‐O‐(propargyl)guanosine with a 2‐cyanoethylthio group is effected by treatment with 2,4,6‐triisopropybenzenesulfonyl chloride and triethylamine to give a 6‐(2,4,6‐triisopropylbenzenesulfonic acid) ester intermediate. Reaction of this key intermediate with 3‐mercaptoproprionitrile and triethylamine, followed by 5′‐dedimethoxytritylation, affords the 6‐(2‐cyanoethylthio)guanosine derivative in a yield of 70%. The 5′‐hydroxy function of this derivative is reacted with commercial N2‐isobutyryl‐5′‐O‐(4,4′‐dimethoxytrityl)‐2′‐O‐tert‐butyldimethylsilyl‐3′‐O‐[(2‐cyanoethyl)‐N,N‐diisopropylaminophosphinyl]guanosine. The reaction product is then converted to the mono‐6‐thioated c‐di‐ GMP biotinylated conjugate under conditions highly similar to those described above for the preparation of the biotinylated c‐di‐GMP conjugate, and isolated in similar yields.

Published: March 2013

The ability to evaluate accurately the response of the environment to climate change ideally involves long‐term continuous in situ measurements of climate and landscape processes. This is the goal of the Nevada Climate‐Ecohydrology Assessment Network (NevCAN), a novel system of permanent monitoring stations located across elevational and latitudinal gradients within the Great Basin hydrographic region (Figure 1). NevCAN was designed, first, to quantify the daily, seasonal, and interannual variability in climate that occurs from basin valleys to mountain tops of the Great Basin in the arid southwest of the United States; second, to relate the temporal patterns of ecohydrologic response to climate occurring within each of the major ecosystems that compose the Great Basin; and, last, to monitor changes in climate that modulate water availability, sequestration of carbon, and conservation of biological diversity.

AbstractNitrogen‐doped graphitic nanoribbons (Nx‐GNRs), synthesized by chemical vapor deposition (CVD) using pyrazine as a nitrogen precursor, are reported for the first time. Scanning electron microscopy (SEM) and high‐resolution transmission electron microscopy (HRTEM) reveal that the synthesized materials are formed by multilayered corrugated GNRs, which in most cases exhibit the formation of curved graphene edges (loops). This suggests that during growth, nitrogen atoms promote loop formation; undoped GNRs do not form loops at their edges. Transport measurements on individual pure GNRs exhibit a linear I–V (current‐voltage) behavior, whereas Nx‐GNRs show reduced current responses following a semiconducting‐like behavior, which becomes more prominent for high nitrogen concentrations. To better understand the experimental findings, electron density of states (DOS), quantum conductance for nitrogen‐doped zigzag and armchair single‐layer GNRs are calculated for different N doping concentrations using density functional theory (DFT) and non‐equilibrium Green functions. These calculations confirm the crucial role of nitrogen atoms in the transport properties, confirming that the nonlinear I–V curves are due to the presence of nitrogen atoms within the Nx‐GNRs lattice that act as scattering sites. These characteristic Nx‐GNRs transport properties could be advantageous in the fabrication of electronic devices including sensors in which metal‐like undoped GNRs are unsuitable.

AbstractPolymer bulk heterojunction solar cells based on low bandgap polymer:fullerene blends are promising for next generation low‐cost photovoltaics. While these solution‐processed solar cells are compatible with large‐scale roll‐to‐roll processing, active layers used for typical laboratory‐scale devices are too thin to ensure high manufacturing yields. Furthermore, due to the limited light absorption and optical interference within the thin active layer, the external quantum efficiencies (EQEs) of bulk heterojunction polymer solar cells are severely limited. In order to produce polymer solar cells with high yields, efficient solar cells with a thick active layer must be demonstrated. In this work, the performance of thick‐film solar cells employing the low‐bandgap polymer poly(dithienogermole‐thienopyrrolodione) (PDTG‐TPD) was demonstrated. Power conversion efficiencies over 8.0% were obtained for devices with an active layer thickness of 200 nm, illustrating the potential of this polymer for large‐scale manufacturing. Although an average EQE > 65% was obtained for devices with active layer thicknesses > 200 nm, the cell performance could not be maintained due to a reduction in fill factor. By comparing our results for PDTG‐TPD solar cells with similar P3HT‐based devices, we investigated the loss mechanisms associated with the limited device performance observed for thick‐film low‐bandgap polymer solar cells.

Published: March 2013

AbstractIn this study, aligned poly(butylene carbonate) nanofibers were fabricated by electrospinning with a high‐speed transfer roller as the receiving device. Cold plasma treatment technology was applied to improve its hydrophilicity and activity to expand its application in biological materials. The morphology of the fibers was investigated with scanning electron microscopy. X‐ray diffraction was used to research the impact of the rotation speed on the crystallization and orientation degree of the crystals. The tensile properties of the materials were evaluated by a universal tester. The surface properties of the fibers pretreated by Helium (He) and those grafted with gelatin were evaluated with water contact angle measurement and X‐ray photoelectron spectroscopy. The experimental results indicate that the order degree of fibers, crystallinity, and orientation of the crystalline region, including the mechanical properties, all increased correspondingly with the rotation speed. After plasma pretreatment, the hydrophilicity was improved significantly, and the grafting reaction was realized successfully. © 2013 Wiley Periodicals, Inc. J. Appl. Polym. Sci., 2013
