Authors: Mohammed Y. B. , Gazali A. K. , Yerima I. , Sani A.
Published: August 2024

Detailed geological mapping coupled with sample collection of sandstone of Dumbulwa Member was carried out at the Ashaka Quarry in the Gongola Basin. The geological mapping showed that the dominant rocks outcropping within the study area are sandstone of the Dumbulwa and shale of the Kanawa Member. Geochemical analysis of sandstone oxides using X-ray Fluorescence (XRF) was carried out using six (6) samples and the investigation reveals the following results; SiO2 range from 30.04% to 87.67% with an average of 57.80%, Al2O3 range from 2.50% to 28.50% with an average of 14.76%, Fe2O3 range from 0.48% 63.67% with an average of 19.03%, CaO range from 0.26% to 1.39% with an average of 0.88%, K2O range from 0.15% to 10.79% with an average of 3.83%, P2O5 range from 0.325% to 0.725% with an average of 0.53%, MgO range from 0.00% to 1.20% with an average of 0.31% and MnO range from 0.02% to 1.67% with an average of 0.33%, Na2O range from 0.00% to 0.00% with an average of 0.00%, TiO2 range from 0.13% to 2.28% with an average of 1.09%, and lastly SO3 range from 0.20% to 0.48% with an average of 0.36%. Enrichment of silica (quartz)- SiO2 over Al2O3 (log SiO2/ Al2O3˂1.5) is a reflection of the duration and intensity of weathering and destruction of other minerals during transportation. This indicates that the sandstone samples of the study area have undergone long period of transportation and have been subjected to intense weathering resulting in the destruction of low temperature minerals like plagioclase and potassium feldspars during the phase of sedimentary cycle. The overall results showed that silica (SiO2) enrichment over Al2O3 by chemical and mechanical processes indicates sandstones maturity. Lack of abundance Na2O and K2O characterized immature sandstones such as arkoses and greywackes. Fe2O3 and MgO enrichment and concentration is a net result of provenance and processes that concentrate and preserved detrital ferromagnesian minerals and their alteration products.

Authors: Lewis Damian , Ilembo Bahati
Published: August 2024

The purpose of this paper was to unfold factors that influence household expenditure using quantile regression methods. Secondary data were used with a probability sample of 9,552 households from the 2017-18 Household Budget Survey (HBS) covered the population residing in private households in Tanzania Mainland. The sample was designed to allow separate estimates for each of the 26 regions of the Tanzania Mainland, as well as urban and rural areas separately at the national level. The 2017-18 HBS adopted a two-stage cluster sample design. In the quantiles analysis, there has been consistency on the effect of household consumption, education level and household age on household expenditure. These showed a statistical significance at 5% level of significance. Except for the 25th quantile, all the three variables were statistically significant in the 50th and 75th quantiles. Further household age, household consumption and marital status of the household head had positive coefficients which implied a positive relationship with the household expenditure. It can thus be concluded that, of the seven independent variables, household age, household consumption and household marital status are the variables which influences positively household expenditure. By considering these findings, policymakers and researchers can develop targeted strategies to address economic disparities and enhance household financial well-being effectively to balance between household income and expenditure.

Authors: Mainda George Makame , Sulle Andrew
Published: August 2024

This study aimed to examine the role of e-government in enhancing service delivery at Muhimbili National Hospital, Tanzania's largest public health facility located in Dar es Salaam. Utilizing a case study research design with a mixed-methods approach, the study combined both quantitative and qualitative research methods to provide a comprehensive understanding of the e-government system's impact. The theoretical framework guiding this study was the Technology Acceptance Model (TAM), which examines users' acceptance of technology based on perceived usefulness and ease of use. The study's population consisted of 4,900 individuals, including hospital staff, patients, and other stakeholders. A sample size of 282 respondents was selected using stratified random sampling to ensure representation from different departments and roles within the hospital. Data collection was conducted through structured questionnaires and semi-structured interviews. Quantitative data were analyzed using the Statistical Package for the Social Sciences (SPSS), with results presented through frequency distribution tables and descriptive statistics. Qualitative data were analyzed using thematic analysis to identify patterns and themes related to the e-government system's impact on service delivery. The findings revealed that the implementation of e-government at Muhimbili National Hospital has significantly improved various aspects of service delivery. For instance, the system has reduced patient waiting times, as reflected in a mean score of 3.68 with a standard deviation (SD) of 1.249. Additionally, the study observed faster transaction processing, with a mean score of 3.18 and SD of 1.108, and more efficient management and retrieval of patient records, achieving a mean score of 3.44 and SD of 1.256. The e-government system also streamlined the allocation of doctors to patients (mean = 3.22, SD = 1.109) and ensured the timely administration of medications and treatments (mean = 3.39, SD = 1.468). Moreover, the system facilitated better integration with service providers, such as insurance companies, as evidenced by a mean score of 3.77 and an SD of 1.268. In conclusion, the adoption of e-government at Muhimbili National Hospital has positively transformed healthcare service delivery by enhancing accessibility, communication, resource management, and data-driven decision-making. The study recommends ongoing impact assessments to measure the tangible benefits of e-government, focusing on key performance indicators such as patient satisfaction, waiting times, and operational efficiency. Additionally, it underscores the importance of strengthening cybersecurity measures to protect patient data and maintain stakeholder trust. Continuous monitoring and evaluation are also advised to ensure that the e-government system evolves with the hospital's needs and goals.

Abstract. We present direct measurements of biogenic volatile organic compound (BVOC)-induced nitrate radical (NO3) reactivity (kVOC) through the diel cycle in the suburban, temperate forest of Rambouillet near Paris (France). The data were obtained in a 6-week summer period in 2022 as part of the Atmospheric ChemistRy Of the Suburban foreSt (ACROSS) campaign. kVOC was measured in a small (700 m2) clearing mainly at a height of 5.5 m above ground level but also at 40 m (for 5 d and nights). At nighttime, mean values (and 25th–75th percentile ranges) of knightVOC(5.5m) = (0.24-0.06+0.32) s−1 and knightVOC(40m) = (0.016-0.007+0.018) s−1 indicate a significant vertical gradient and low NO3 reactivity above the canopy, whereas knightVOC(5.5 m) showed peak values of up to 2 s−1 close to the ground. The strong vertical gradient in NO3 reactivity could be confirmed by measurements between 0 and 24 m on one particular night characterized by a strong temperature inversion and is a result of the decoupling of air masses aloft from the ground- and canopy-level sources of BVOCs (and nitric oxide, NO). No strong vertical gradient was observed in the mean daytime NO3 reactivity, with kdayVOC(5.5m) = (0.12 ± 0.04) s−1 for the entire campaign and kdayVOC(40m) = (0.07 ± 0.02) s−1 during the 5 d period. Within the clearing, the fractional contribution of VOCs to the total NO3 loss rate coefficient (ktot, determined by photolysis, reaction with NO and VOCs) was 80 %–90 % during the night and ∼ 50 % during the day. In terms of chemical losses of α-pinene below canopy height in the clearing, we find that at nighttime hydroxyl radicals (OH) and ozone (O3) dominate, with NO3 contributing “only” 17 %, which decreases further to 8.5 % during the day. Based on measured OH, measured O3, and calculated NO3 concentrations, the chemical lifetime of BVOCs at noon is about 1 h and is likely to be longer than timescales of transport out of the canopy (typically of the order of minutes), thus significantly reducing the importance of daytime in-canopy processing. Clearly, in forested regions where sufficient nitric oxide and nitrogen dioxide (NOx) is available, the role of NO3 and OH as initiators of BVOC oxidation is not strictly limited to nighttime and daytime, respectively, as often implied in e.g. atmospheric chemistry textbooks.

Abstract. Mandatory use of low-sulfur fuel according to the global sulfur limit regulation has reduced the emissions of SO2 and particulate matter (PM) significantly on ships, and it also leads to a very large uncertainty in volatile organic compound (VOC) emissions. Therefore, an on-board test of VOCs from nine typical cargo ships with low-sulfur fuels in China was carried out in this study. Results showed that the emission factor of VOCs (EFVOCs) varied largely from 0.09 to 3.01 g kg−1 of fuel, with domestic coastal cargo ships (CCSs) having the highest level, followed by inland cargo ships (ICSs) and ocean-going vessels (OGVs). The switch of fuels from heavy fuel oil (HFO) to diesel increased EFVOCs by 48 % on average, which enhanced both O3 and secondary organic aerosol (SOA) formation potential, especially for OGVs. Besides, the use of low-sulfur fuels for OGVs also led to a significant increase in naphthalene emission. These indicated that the implementation of a global ultra-low-sulfur oil policy in the near future needs to be optimized. Moreover, aromatics were the most important common contributors to O3 and SOA in ship exhausts, which need to be controlled as a matter of priority. It was also found that the benzene, toluene, and ethylbenzene ratio of 0.5:0.3:0.2 on average could be considered a diagnostic characteristic to distinguish ship emissions from other emission sources.
Monitoring cropland daily carbon dioxide exchange at field scales with Sentinel-2 satellite imagery

Published: August 2024

Abstract. Improving the accuracy of monitoring cropland CO2 exchange at heterogeneous spatial scales is of great importance for reducing spatial and temporal uncertainty in estimating terrestrial carbon (C) dynamics. In this study, an approach to estimate daily cropland C fluxes is developed and tested by combining time series of field-scale eddy covariance (EC) CO2 flux data and Sentinel-2 satellite-based vegetation indices (VIs) after appropriately accounting for the spatial alignment between the two time series datasets. The study was carried out for an agricultural field (118 ha) in the lowlands of northeastern Germany. The ability of different VIs to estimate daily net ecosystem exchange (NEE) and gross primary productivity (GPP) based on linear regression models was assessed. Most VIs showed high (>0.9) and statistically significant (p<0.001) correlations with GPP and NEE, although some VIs deviated from the seasonal pattern of CO2 exchange. By contrast, correlations between ecosystem respiration (Reco) and VIs were weak and not statistically significant, and no attempt was made to estimate Reco from VIs. Linear regression models explained generally more than 80 % and 70 % of the variability in NEE and GPP, respectively, with high variability among the individual VIs. The performance in estimating daily C fluxes varied among VIs depending on the C flux component (NEE or GPP) and observation period. Root mean square error (RMSE) values ranged from 1.35 g C m−2 d−1 using the green normalized difference vegetation index (GNDVI) for NEE to 5 g C m−2 d−1 using the simple ratio (SR) for GPP. This equated to an underestimated net C uptake of only 41 g C m−2 (18 %) and an overestimation of gross C uptake of 854 g C m−2 (73 %). Differences between the measured and estimated C fluxes were mainly explained by the diversion of the C flux and VI signal during winter when C uptake remained low, while VI values indicated an increased C uptake due to relatively high crop leaf area. Overall, the results exhibited similar error margins to mechanistic crop models. Thus, they indicated the suitability and expandability of the proposed approach for monitoring cropland C exchange with satellite-derived VIs.
Towards a real-time modeling of global ocean waves by the fully GPU-accelerated spectral wave model WAM6-GPU v1.0

Published: August 2024

Abstract. The spectral wave model WAM (Cycle 6) is a commonly used code package for ocean wave forecasting. However, it is still a challenge to include it into the long-term Earth system modeling due to the huge computing requirement. In this study, we have successfully developed a GPU-accelerated version of the WAM model that can run all its computing-demanding components on GPUs, with a significant performance increase compared with its original CPU version. The power of GPU computing has been unleashed through substantial efforts of code refactoring, which reduces the computing time of a 7 d global 1/10° wave modeling to only 7.6 min in a single-node server installed with eight NVIDIA A100 GPUs. Speedup comparisons exhibit that running the WAM6 with eight cards can achieve the maximum speedup ratio of 37 over the dual-socket CPU node with two Intel Xeon 6236 CPUs. The study provides an approach to energy-efficient computing for ocean wave modeling. A preliminary evaluation suggests that approximately 90 % of power can be saved.
Monthly new water fractions and their relationships with climate and catchment properties across Alpine rivers

Published: August 2024

Abstract. The Alps are a key water resource for central Europe, providing water for drinking, agriculture, and hydropower production. Thus, understanding runoff generation processes of Alpine streams is important for sustainable water management. It is currently unclear how much streamflow is derived from old water stored in the subsurface and how much stems from more recent precipitation that reaches the stream via near-surface quick flow processes. It is also unclear how this partitioning varies across different Alpine catchments in response to hydroclimatic forcing and catchment characteristics. Here, we use stable water isotope time series in precipitation and streamflow to quantify the young water fractions (Fyw; i.e., the fraction of water younger than approximately 2–3 months) and new water fractions (Fnew; here, the fraction of water younger than 1 month) in streamflow from 32 Alpine catchments. We contrast these measures of water age between summer and winter and between wet and dry periods and then correlate them with hydroclimatic variables and physical catchment properties. New water fractions varied between 3.5 % and 9.6 %, with values of 9.2 % in rainfall-dominated catchments, 9.6 % in hybrid catchments, and 3.5 % in snow-dominated catchments (mean across all catchments of 7.1 %). Young water fractions were approximately twice as large (reflecting their longer timescale) and ranged between 10.1 % and 17.6 %, with values of 17.6 % in rainfall-dominated catchments, 16.6 % in hybrid catchments, and 10.1 % in snow-dominated catchments (mean across all catchments of 14.3 %). New water fractions were negatively correlated with catchment size (Spearman rank correlation, rS, of −0.38), q95 baseflow (rS=-0.36), catchment elevation (rS=-0.37), total catchment relief (rS=-0.59), and the fraction of slopes steeper than 40° (rS=-0.48). Large new water fractions, implying faster transmission of precipitation to streamflow, are more prevalent in small catchments, at low elevations, with small elevation differences, and with large fractions of forest cover (rS=0.36). New water fractions averaged 3.3 % following dry antecedent conditions, compared with 9.3 % after wet antecedent conditions. Our results quantify how hydroclimatic and physical drivers shape the partitioning of old and new waters across the Alps, thus indicating which landscapes transmit recent precipitation more readily to streamflow and which landscapes tend to retain water over longer periods. Our results further illustrate how new water fractions may find relationships that remained invisible with young water fractions.

Published: August 2024

A maioria das fraturas em idosos acima de 75 anos se dá em fêmur proximal e está associada principalmente a traumas de baixa energia. Essas lesões impactam negativamente no equilíbrio físico, mental, funcional e social do idoso, sendo fatores importantes de morbimortalidade. O presente estudo, baseado em uma revisão integrativa da literatura, buscou avaliar os principais fatores relacionados a fraturas de fêmur proximal em idosos. Após a avaliação dos artigos, foi evidenciada significativa relação entre a alteração dos sistemas responsáveis pelo equilíbrio, a redução da força muscular e a perda de flexibilidade, além do declínio da qualidade das articulações e do tônus muscular, com a ocorrência de fraturas de fêmur. Além disso, doenças como hipertensão arterial sistêmica, sedentarismo e a presença de pisos escorregadios nas residências também aumentam a ocorrência dessas fraturas. Para mais, a baixa densidade mineral óssea é vista como maior preditor sensível de fraturas em vários estudos e a osteoporose é o fator mais relevante nas fraturas do terço proximal do fêmur. Diante disso, evidencia-se que o envelhecimento fisiológico é fator de risco importante para a ocorrência de fraturas de fêmur. Aliado a isso, a existência de comorbidades torna ainda maior o risco para essas lesões. Tal fato evidencia a importância de um acompanhamento multidisciplinar do idoso e o incentivo à prática de exercício físico resistido, associados ao controle de doenças crônicas, na redução da incidência de fraturas de fêmur proximal.

A Geografia Humanista e a Condição Pós-humana
Authors: Do Nascimento Francyjonison Custodio
Published: August 2024

A Geografia humanista nasceu no século XX num contexto de contestação de postulados geográficos quantativistas e numa mescla de efervescências cultural e socioeconômicas. Ela tem, como grande pressuposto teórico, uma nova concepção de espaço, fundada a partir de várias correntes filosóficas. Tal concepção proporcionou um programa de pesquisa variado, que tem como centro a experiência humana na terra e os significados na compreensão da relação das pessoas com lugares e ambientes geográficos. De certa forma, a Geografia humanista foi “provada” por diversas críticas e continua a contribuir com o debate geográfico. Partindo desse entendimento, o artigo objetiva promover um diálogo entre a Geografia humanista e a condição pós-humana, um campo de pesquisa emergente que discute novas formulações do humano a partir da aceleração do capitalismo, da tecnologia e da devastação da natureza. Assim sendo, este trabalho é composto por uma revisão bibliográfica aliada a uma reflexão teórica a respeito das ligações entre a condição pós-humana e a Geografia humanista. Conclui-se que a Geografia humanista, longe de ser uma abordagem caduca, ainda pode auxiliar nas questões geográficas do tempo presente bem como a crise ecológica, ao propor estudos interdisciplinares em busca de um habitar geopoético e o repensar dos valores fundados no humanismo iluminista europeu
O Papel do Terceiro Setor na Promoção da Educação Ambiental
Authors: Fares Paulo Rodolfo , Siqueira Agnéia Luciana Lopes de
Published: August 2024

A obrigatoriedade de promover a Educação Ambiental em todos os níveis de ensino encontra respaldo legal na Constituição Federal de 1988, porém viu-se que a Conferência de Estocolmo, em 1972, surgiu como uma revolução de conceitos e princípios, colocando o Meio Ambiente em maior destaque, em relação à sociedade. Destaca-se o princípio do desenvolvimento sustentável, que consiste na harmonia entre o desenvolvimento econômico e social, respeitando sobretudo, um meio ambiente saudável. A degradação ambiental, direcionada principalmente, por um comportamento cultural e consumista, começa a apresentar níveis catastróficos até então desconhecidos, ou até mesmo, ignorados que necessitam da consciência coletiva direcionada a partir da educação, para assim, ser inibida. Neste sentido, a pesquisa apresenta a educação ambiental como uma importante ferramenta na implantação de uma política ambiental que deve ser direcionada a todos os níveis de ensino. O desenvolvimento da educação ambiental formará um cidadão consciente do seu papel na sociedade, preservando o meio ambiente para as gerações presentes e futuras. A metodologia do artigo baseia-se em análise documental e revisão de literatura, investigando a legislação e a aplicação da Educação Ambiental no âmbito do terceiro setor. Emprega-se também uma abordagem qualitativa para examinar como a educação pode influenciar comportamentos e promover a sustentabilidade, visando a formação de cidadãos conscientes e responsáveis pelo meio ambiente.

The financial industry is transforming with the advent of Natural Language Generation (NLG), a subset of Natural Language Processing (NLP), which automates data conversion into coherent and contextually relevant narratives. This paper presents a comprehensive review of NLG's application in financial report automation, tracing its evolution from template-based methods to advanced deep learning and knowledge graph techniques. We discuss the relevance of NLG in automating report generation, its role in enhancing data analysis and decision-making, and its potential to improve investor communications and compliance with regulations. The paper identifies research gaps, including the need for optimization, accuracy improvement, and the integration of machine learning models for better classification and prediction. A proposed methodology for structured report generation is outlined, leveraging deep learning architectures such as RNNs and LSTMs. Future work aims to address these gaps and further integrate NLG into financial reporting, promising to streamline processes, reduce costs, and provide more personalized and insightful financial narratives.

Published: August 2024

Purpose – This research paper aims to create a realistic understanding of the favorable and unfavorable experiences that employees have as a result of adopting artificial intelligence (AI) or resorting to the old manual HR methods. It explains the difficulties and the benefits associated with developing human resources in light of the use of artificial intelligence or the old manual HR methods. Design/Methodology/Approach – For this study, the researcher employed a qualitative and exploratory research methodology. The primary element of the qualitative method which is adjusted to comprehend the literature, theories, motivations, viewpoints, and views in order to answer the study issue is exploratory research. This research used data from secondary sources. Findings – The study found that some firms spend over two million hours annually conducting manual HR performance reviews and evaluations. This is a significant amount of time spent on a process that is unreliable because it relies on people's opinions and prior performance. Real-time Artificial intelligence AI-driven assessments not only enable incentives and praise for good performances immediately, but they also ensure accuracy throughout the entire process and sound an alarm if targets are not met on time or performance standards are declining. From the extensive review of literature, it was found that Artificial Intelligence has a positive and significant influence on HR function of employee performance evaluation. Practical Implications – The study recommends a more robust top-level AI design and implementation within the entrepreneurial ecosystem and a robust application of Artificial Intelligence on HR function of employee performance evaluation. Originality/value – This research makes the unique contribution of establishing a qualitative finding that will revolutionize the entrepreneurial ecosystem for more employee productivity and satisfaction.

In this study, a microstrip circular patch antenna is designed having a metamaterial-based (MTM) ground plane to detect manufacturing defects of short circuits and open circuits on printed circuit boards (PCB). In that regard, PCB specimens of FR-4 as the substrate and copper microstrip lines as the conductive wiring lines are designed and manufactured. Five vertical copper lines printed side by side on the top of the substrate are used to demonstrate the working mechanism of the designed antenna sensor. Two different defect scenarios of open and short circuits with controlled locations are studied to determine variations in the return loss data of the proposed structure. MTM cell structures with cross lines enclosed by an octagon ring are periodically placed as part of the ground plane of the proposed antenna to obtain higher sensitivity of the designed and manufactured sensor. Antenna return loss behaviors in terms of the locations of the faults are employed to prepare a database to detect not only the presence of the faults but also determine their locations. Since the samples to be measured are not irreversibly damaged during the testing process, the proposed design can be considered a non-destructive measurement method to provide information about the type and location of defects with real-time measurement data.

Published: August 2024

BACKGROUND

Chemoresistance is the primary contributor to distant metastasis in the context of neoadjuvant chemoradiotherapy (nCRT) for rectal cancer. However, the underlying mechanisms remain elusive.

AIM

To detect the differential expression profiles of plasma exosomal microRNAs (miRNAs) in poor and good responders and explore the potential mechanisms of chemoresistance.

METHODS

In this study, the profiles of plasma exosomal miRNAs were compared in two dimensions according to treatment responses (poor/good responders) and treatment courses (pre/post-nCRT) using RNA sequencing.

RESULTS

Exosome hsa-miR-483-5p was up-regulated in good responders post-nCRT. Bioinformatics analysis revealed that the target genes of hsa-miR-483-5p were mainly enriched in tumor-specific pathways, such as the MAPK signaling pathway, EGFR tyrosine kinase inhibitor resistance, Toll-like receptor signaling pathway, VEGF signaling pathway, and mTOR signaling pathway. Further analysis indicated that MAPK3, RAX2, and RNF165 were associated with inferior recurrence-free survival in patients with rectal cancer, and the profiles of MAPK3, TSPYL5, and ZNF417 were correlated with tumor stage. In addition, the expression profiles of MAPK3, RNF165, and ZNF417 were negatively correlated with inhibitory concentration 50 values. Accordingly, an hsa-miR-483-5p/MAPK3/RNF 165/ZNF417 network was constructed.

CONCLUSION

This study provides insights into the mechanism of chemoresistance in terms of exosomal miRNAs. However, further research is required within the framework of our established miRNA-mRNA network.

Published: August 2024

BACKGROUND

Modern pharmacological studies have confirmed that plant-derived compounds from Puerariae flos (PF) has significant biological activities against liver damage, tumors and inflammation. Kakkatin is an isoflavone polyphenolic compound isolated from PF flower. However, the effect of kakkatin and its derivatives on anti-tumor has not been well explored.

AIM

To design and synthesize a kakkatin derivative [6-(hept-6-yn-1-yloxy)-3-(4-hydroxyphenyl)-7-methoxy-4H-chromen-4-one (HK)] to explore its anti-tumor biological activity.

METHODS

Hept-6-yn-1-yl ethanesulfonate was introduced to replace hydrogen at the hydroxyl position of kakkatin phenol, and the derivative of kakkatin was prepared; the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide was used to detect cell viability, a clone formation assay was adopted to detect cell proliferation, apoptosis, necrosis, and cell cycles were analyzed by Annexin V/propidium iodide staining and flow cytometry. Cell migration and invasion ability were evaluated by cell scratch assay and transwell assay. The potential mechanism of HK on hepatocellular carcinoma (HCC) SMMC-7721 cells was explored through network pharmacology and molecular docking, and finally real-time PCR assays was used to verify the potential targets and evaluate the biological activity of HK.

RESULTS

Compared with kakkatin, the modified HK did not significantly increase the inhibitory activity of gastric cancer MGC803 cells, but the inhibitory activity of HCC SMMC-7721 cells was increased by about 30 times, with an IC50 value of 2.5 μM, and the tumor inhibition effect was better than cisplatin, which could significantly inhibit the cloning, invasion and metastasis of HCC SMMC-7721 cells, and induce apoptosis and G2/M cycle arrest. Its mechanism of action is mainly related to the upregulation of PDE3B and NFKB1 target proteins in the cAMP pathway.

CONCLUSION

HK have a significant inhibitory effect on HCC SMMC-7721 cells, and the targets of their action may be PDE3B and NFKB1 proteins in the cAMP pathway, making it a good lead drug for the treatment of HCC.

Published: August 2024

BACKGROUND

Non-Hodgkin's lymphoma (NHL) is a malignant tumor that originates from the lymphoid tissues and can potentially affect numerous organs within the body. Among these, the skin stands out as one of the primary sites affected by NHL, often presenting with multiple extra-nodal manifestations. In this report, we present an unusual case of NHL involving chronic wounds in the lower extremities that were difficult to heal. The scars were successfully treated using radiotherapy in combination with extended excision debridement and peroneal artery perforator flap grafting, resulting in satisfactory outcomes.

CASE SUMMARY

A 19-year-old male patient presented with ulceration of the skin on the left calf near the ankle accompanied by purulent discharge. Subsequent pathologic biopsy confirmed a diagnosis of NHL (extranodal NK/T-cell lymphoma, nasal type). Initial treatment comprised local radiotherapy and wound care; however, the wound exhibited prolonged non-healing. Consequently, the patient underwent a series of interventions including radiotherapy, wound enlargement excision debridement, and peroneal artery perforator flap grafting. Ultimately, successful healing was achieved with favorable postoperative outcomes characterized by good texture of the flap without any signs of rupture or infection.

CONCLUSION

The combination of radiotherapy, wound enlargement excision debridement, and peroneal artery perforator flap grafting may present a favorable treatment modality for chronic non-healing lower leg wounds resulting from NHL.
Six transmembrane epithelial antigens of the prostate to illustrate inflammatory response in gastrointestinal cancers
Authors: Wu Yi-Han , Luo Lian-Xiang
Published: August 2024

Gastrointestinal cancer (GIC) is a common and widespread form of tumor, with colonoscopy and upper gastrointestinal endoscopy available to detect relevant precancerous polyps and lesions. However, many patients are already in the late stages when first diagnosed with such cancer, resulting in a poor prognosis. Thus, it is necessary to explore new methods and research directions in order to improve the treatment of GIC. Given the specific nature of the gastrointestinal tract, research should focus on the mechanisms of various inflammations and the interactions between food entering and exiting from the gastrointestinal tract and cancer cells. Interestingly, six transmembrane epithelial antigens of the prostates (STEAPs) have been found to be significantly linked to the progression of malignant tumors, associated with intracellular oxidative stress and playing a major role in inflammation with their structure and function. This paper explores the mechanism of STEAPs in the inflammatory response of GIC, providing a theoretical basis for the prevention and early intervention of GIC. The basic properties of the STEAP family as metal reductase are also explained. When it comes to intervention for GIC prevention, STEAPs can affect the activity of Fe3+, Cu2+ reductase and regulate metal ion uptake in vivo , participating in inflammation-related iron and copper homeostasis. Thus, the mechanism of STEAPs on inflammation is of important value in the prevention of GIC.

Cancer, the second leading global cause of death, impacts both physically and emotionally. Conventional treatments such as surgeries, chemotherapy, and radiotherapy have adverse effects, driving the need for more precise approaches. Precision medicine enables more targeted treatments. Genetic mapping, alongside other molecular biology approaches, identifies specific genes, contributing to accurate prognoses. The review addresses, in clinical use, a molecular perspective on treatment. Biomarkers like alpha-fetoprotein, beta-human chorionic gonadotropin, 5-hydroxyindoleacetic acid, programmed death-1, and cytotoxic T lymphocyte-associated protein 4 are explored, providing valuable information. Bioinformatics, with an emphasis on artificial intelligence, revolutionizes the analysis of biological data, offering more accurate diagnoses. Techniques like liquid biopsy are emphasized for early detection. Precision medicine guides therapeutic strategies based on the molecular characteristics of the tumor, as evidenced in the molecular subtypes of breast cancer. Classifications allow personalized treatments, highlighting the role of trastuzumab and endocrine therapies. Despite the benefits, challenges persist, including high costs, tumor heterogeneity, and ethical issues. Overcoming obstacles requires collaboration, ensuring that advances in molecular biology translate into accessible benefits for all.
