In recent years,cancer immunotherapy has introduced novel treatments,such as monoclonal antibodies,which have facilitated targeted therapies against tumor cells.Programmed death-1(PD-1)is an immune checkpoint expressed in T cells that regulates the immune system’s activity to prevent over-activation and tissue damage caused by inflammation.However,PD-1 is also expressed in tumor cells and functions as an immune evasion mechanism,making it a therapeutic target to enhance the immune response and eliminate tumor cells.Consequently,immune checkpoint inhibitors(ICIs)have emerged as an option for certain tumor types.Nevertheless,blocking immune checkpoints can lead to immune-related adverse events(irAEs),such as psoriasis and cytokine release syndrome(CRS),as exemp-lified in the clinical case presented by Zhou et al involving a patient with adva-nced gastric cancer who received sintilimab,a monoclonal antibody targeting PD-1.Subsequently,the patient experienced exacerbation of psoriasis and CRS.The objective of this editorial article is to elucidate potential immunologic mechanisms that may contribute to the development of CRS and psoriasis in patients receiving ICIs.It is crucial to acknowledge that while ICIs offer superior safety and efficacy compared to conventional therapies,they can also manifest irAEs affecting the skin,gastrointestinal tract,or respiratory system.In severe cases,these irAEs can lead to life-threatening complications such as circulatory shock or multiorgan failure.Consequently,it is recommended that patients receiving ICIs undergo regular monitoring to identify and manage these adverse events effectively. 展开更多

The Municipality of Carranglan is a rural community where agriculture is the main source of livelihood. The Kalanguya Ancestral Domain (KAD) is also located in the area, and it provides a home for the Kalanguya indigenous cultural community. They have fled to the area for a variety of reasons. Despite its rural setting, Carranglan is regarded as a first-class municipality and the largest municipality in Nueva Ecija. This study described and documented the socio-economic profile, and existing issues and problems the Kalanguya Indigenous Peoples (IPs) experienced in their milieu, especially in terms of environmental protection. Recognizing and valuing their perspectives is vital for inclusive development. This study also situated the current status and conditions of the IPs, who generally live below the poverty line and face a range of plights and challenges. As part of safeguarding indigenous rights and interests, this study was undertaken after series of consultations with community elders and leaders. Key informant interviews, household surveys, semi-structured interviews, focused-group discussion (FGD), and direct observations were used to elicit information. Many of the respondents are elementary undergraduates which show that the community had lacked access to education. The following are the primary socioeconomic issues confronting IPs: insufficient access to potable water, suboptimal agricultural productivity, meager monthly income, and a dearth of supplementary and alternative livelihood opportunities. Forest fires, landslides, encroachment of illegal loggers, and concerns about wildlife resources are some of the current environmental issues they have encountered. The local population was supportive of plans and actions targeted at improving the environment. This reveals that the IPs possess unique indigenous forest expertise that enables them to properly manage natural resources. 展开更多

The Philippines is one of the most hazard prone and vulnerable countries in the world to climate change effects due to its geographical location. Climate change is already happening and affecting many places causing huge problems to coastal ecosystems. Vulnerability and disaster assessment and mapping in coastal areas are essential tasks and undertakings for coastal disaster risk management. The objectives of this study were to assess the climate change vulnerability and disaster risks in the four municipalities (Sta. Cruz, Candelaria, Masinloc and Palauig) of Zambales and to determine the climate change community-based adaptation (CBA) and ecosystem-based adaptation (EBA) strategies. Remote sensing, GIS, secondary data gathering and key informant interview were used to assess vulnerability and disaster risks and mapping in the four municipalities. Survey questionnaire, focus group discussion and key informant interview were utilized in gathering data for the determination of climate change adaptation strategies. Using remote sensing technology, it was revealed that coastline changes have occurred in the shorelines of the four coastal municipalities after a decade. Sea level rise happened in Sta. Cruz and Masinloc, Zambales while there was build-up of soil in the coastline of Candelaria and Palauig, Zambales. Twelve hazard maps, 12 vulnerability maps and 12 disaster risk maps were generated for the three major disasters (flood, landslide, storm surge) in the four coastal municipalities. Based on the flood vulnerability and disaster risk assessment, the municipality of Palauig was found to be the most prone to flooding while the municipality of Candelaria was found to be the most vulnerable to landslide compared to other municipalities. All coastal barangays in the four municipalities were susceptible to storm surge. The four coastal municipalities were conducting community-based adaptation (CBA) and ecosystem-based adaptation (EBA) approaches in order to protect their coastal resources from the damaging impacts of climate change and improve the resilience of their local communities. 展开更多

Climate change continues to intensify existing disaster risks and vulnerabilities in the Philippines. Thus, implementation of climate change adaptation strategies is vital to counter the effects of climate change. It is in this context that this study was undertaken to analyze the need or urgency to adopt community and ecosystem-based adaptation strategies among selected coastal barangays (villages) of Masinloc, Zambales, Philippines. Various methods of data collection were utilized such as secondary data collection, primary data collection through household survey, key informant interviews, and focus group. Results of the study indicate that in terms of community-based adaptation strategies, all of the seven barangays in Masinloc have moderate necessity. However, only Barangays Bani and Collat have high adaptation capacity in terms of infrastructure and disaster preparedness. The execution of several community-based adaptation strategies helps these barangays to respond immediately and appropriately to the moderate risk posed by floods and storm surges. On the other hand, in terms of ecosystem-based adaptation strategies, all of the seven barangays have moderate necessity which implies that they have moderate vulnerability and risk to flood and storm surge but have high adaptation capacity in terms of the conservation and protection of coastal resources (mangroves and sea grasses). The barangays implemented the necessary ecosystem-based adaptation mechanisms that they might need in the future. This only means that when they are faced with disaster, the local communities are prepared to respond appropriately and to cope up with the effects of extreme weather events which lead to floods and storm surge. Even though most of the ecosystem-based adaptation strategies are conducted by the seven barangays, there are several community-based adaptation strategies that are still lacking which will protect them from the effect of floods and storm surges. Hence, carrying out the missing adaptation strategies, both community-based and ecosystem-based, will help in improving the adaptive capacity of the affected barangays and will help them become more resilient to the amplified effects of climate change. 展开更多

Background and Aim: Despite the fact that acute appendicitis is the most common surgical emergency all around the world, its diagnosis is still based on clinical evaluation and accuracy of the diagnosis depending on experience. The aim of this study is to evaluate the role of inflammatory markers in diagnosis of acute appendicitis. Material and Method: The study includes 77 cases with histopathologically proven acute appendicitis and 17 control cases. Blood samples were obtained from all cases and C-reactive protein (CRP), Granulocyte Colony Stimulating Factor (G-CSF) and Total Antioxidant Capacity (TAC) were measured. Findings: In cases with acute appendicitis, CRP and G-CSF levels were found to be related to acute appendicitis;however, TAC was not affected by the disease process. Moreover, CRP and G-CSF levels were correlated with the disease severity. Conclusion: Both CRP and G-CSF can be used in diagnosis of acute appendicitis. Furthermore, increased CRP level can be a marker to show advanced cases. However, G-CSF is not an effective marker to show disease severity. 展开更多

Desert-fringe vegetation growing over bright, sandy soils reduces the surface albedo from above 0.4 to well below 0.3. Called desert-scrub, these shrubs form a predominantly vertical clumps protruding from the soil-level, thereby significantly increasing the coefficient of turbulent heat transfer from the surface. The impact on global and desert-belt climate of changes in these two surface characteristics was simulated by a multi-layer energy balance tnodel. Evaluated only as a forcing to a further climatic change (that is, without accounting for any possible feedbacks) the results are: if vegetation (such as apparently existed under the warmer climate of 6,000 BP ) grows over large areas in the arid, currently bare-soil regions, the annual Northern Hemisphere surface temperature increases by 0.7t (by 0.6'C in July ), the surface temperature over land in the 20-30°N zone increases by 0.9℃ in both the annual and the July means, and the land-ocean annual temperature contrast in this zone increases by 0.25℃(0.2° in July). These results represent the combined influence of the reduction in the surface albedo and of the increase in the coefficient of turbulent heat transfer. In the desert-belt zones, the increase in the transfer coefficient sharply reduces the land temperature and the land-ocean temperature contrast from the values produced by the albedo change alone. This reduction must be attributed to the increased land-to-ocean circulation (which our model does not evaluate explicitly). Considering that a stronger circulation (resulting from land-ocean temperature contrast) generally forces a higher rainfall, the vegetation which emerged in the arid regions during the post-glacial optimum should be considered a significant positive feedback towards a still warmer, and also a more pluvial, climate. Our study may have implications for the 21st century, if the global warming expected from the enhanced greenhouse effects is accompanied by increased precipitation over the continents. 展开更多

In this study, the rice straw was hydrolysed by using 3.0% (w/v) H2SO4 followed by enzymatic hydrolysis. The rice straw hydrolysate obtained was treated with charcoal powder and the optimal condition of detoxification with charcoal powder was investigated. The results showed that the optimal condition for detoxification was the use of 2.5 grams of non-sterilized charcoal powder in 100 mL hydrolysate. The mixture was operated at pH 5.0, 30 ℃ and 160 rpm for 5 min. The detoxified hydrolysate was then used for ethanol production using P. stipitis TISTR 5806. The condition of the detoxified hydrolysate fermentation which gave maximum ethanol concentration of 21 g/L was at pH 5.0, 30 ℃ and 160 rpm for 72 h. Without detoxification, the P. stipitis TISTR 5806 could not however utilize the hydrolysate for ethanol production. 展开更多

This paper introduces a new prefabricated recyclable double-row piles retaining system for excavations in silty clay ground.Laboratory model test and numerical simulation are conducted to study the system behavior upon excavation.The horizontal displacement(δ_(h)),Von Mises stress(δ_(M)),strain(ε),ground surface settlement(δ_(v)),and earth pressure are systematically investigated.Furthermore,the monitoring data of 13 excavation cases supported by double-row piles retaining system are presented and discussed.The experimental results can basically match the numerical results,and the maximumδ_(M),maximum bending moment(M_(max)),maximum horizontal displacement(δ_(hm))of structural members are all less than the tolerance limits.The ground surface settlement model of double-row piles retaining system consists of three zones,i.e.,rebound influence zone,primary influence zone and secondary influence zone.The dhm values are 0.07%–1.42%of the excavation depth(He).The maximum ground surface settlement(δ_(vm))is generally less than dhm.The ratio ofδ_(vm)=δ_(hm)varies between 0.09 and 0.76,with an average value of 0.5.The observed earth pressure on the retained side of front pile(paf)is about 0.53–0.57γH below the excavation surface.Above the excavation surface,p_(af)decreases dramatically when getting closer to the ground surface. 展开更多

为揭示土壤微生物膜对沙生植物幼苗光合和荧光特性的影响,以沙冬青(Ammopiptanthus mongolicus)和沙打旺(Astragalus laxmannii)幼苗为研究对象,设置不同菌剂施用方式(喷施、混施)和施用量(0、1、3、5、7 g·kg^(-1)和10g·kg^(... 为揭示土壤微生物膜对沙生植物幼苗光合和荧光特性的影响,以沙冬青(Ammopiptanthus mongolicus)和沙打旺(Astragalus laxmannii)幼苗为研究对象,设置不同菌剂施用方式(喷施、混施)和施用量(0、1、3、5、7 g·kg^(-1)和10g·kg^(-1))开展盆栽试验,比较分析土壤微生物膜形成后植物气体交换和叶绿素荧光特征。结果表明:(1)当菌剂施用量>3 g·kg^(-1)时,固结层硬度、厚度和土壤脲酶、蔗糖酶活性均显著高于对照组(P<0.05)。(2)在3~7 g·kg^(-1)菌剂处理组沙打旺净光合速率显著高于对照组(P<0.05),且蒸腾速率(Tr)、净光合速率(Pn)和胞间CO_(2)浓度(Ci)均显著高于沙冬青(P<0.05)。(3)当菌剂施用量>5 g·kg^(-1)时沙打旺最大光化学效率(F_(v)/F_(m))显著高于对照组(P<0.05)。除3 g·kg^(-1)处理组之外,沙冬青F_(v)/F_(m)和光化学猝灭系数(QP)均高于沙打旺。(4)土壤特性、光合气体交换和叶绿素荧光三者为部分中介模型,土壤特性的改变能直接影响沙冬青和沙打旺叶绿素荧光特性。土壤微生物膜使固结层硬度和厚度平均提高3.84%和152.85%,土壤过氧化氢酶、脲酶和蔗糖酶活性平均增强93.37%、170.68%和256.03%。其通过改善土壤质量、提高叶片气孔导度从而增强沙冬青和沙打旺光合效率和能力,使沙打旺和沙冬青净光合速率平均提高28.48%,F_(v)/F_(m)平均提高0.84%。 展开更多
