. The biochar-palygorskite composite (BC/PAL) was synthesized and applied in the remediation of soil polluted by heavy metals. The efficiency of BC/PAL on the soil physicochemical property, the bioavailability and chemical fraction of Cd and Pb in the soil, the growth of the plants and heavy metals accumulation in maize ( Zea mays L.) were investigated by pot and incubation experiments. The data show that BC/PAL can greatly enhance the stability of Cd and Pb, facilitating their transition from labile to stable components. And the composite can also reduce the CaCl 2 -extractable Cd and Pb with a maximum reduction efficiency of 57.76% and 42.81%, respectively. The fresh weight of corn seedlings had a more than sevenfold increase and the accumulation of Cd and Pb in shoot and root parts decreased significantly. BC/PAL can effectively improve the contents of soil available nutrients, soil enzyme activity, and organic carbon content. It can significantly reduce the bioavailability and ecotoxicity of Cd and Pb in the soil. The biochar-palygorskite composites can be further investigated as an efficient

. The Yellow River Source Area (YRSA) in China is an important water yield and water conservation area in the Yellow River basin. Alterations in climate and landscape patterns have had a significant impact on the water yield and conservation services of the YRSA. In this study, we used a modified parameter water yield module of the InVEST model to calculate water yield and a modified equation to calculate water conservation in order to evaluate the spatiotemporal changes in water yield and water conservation services in the YRSA from 2000 to 2020. The results show that water yield and water conservation in the YRSA increased at rates of 14.72 mm/5a and 10.03 mm/5a, respectively, from 2000 to 2020, and both showed a decreasing pattern from southeast to northwest. Precipitation is the main driving factor of water ecosystem services in the YRSA. An appropriate increase in vegetation coverage is conducive to an increase in water yield and water conservation, and an increase in grassland and forest area has a positive impact on water yield and water conservation services. This study provides insights into high-quality development and water resource protection in the YRSA.

. A remote sensing strategy was investigated to evaluate how temperature and rainfall affect the deforestation of economically important tree species in Wudil, Kano Nigeria. The research was carried out in Wudil. To assess the vulnerability of the study area to desertification and the abundance of economic tree species. Landsat satellite products (Landsat 5, 7, 8. were used as the sources of remote sensing imageries. These products were sourced for intervals of ten years, from 1986 to 1999, 2006 to 2016, and 2020. Standardized temperature anomaly and precipitation index from 1986 to 2020 were analyzed using primary and secondary data obtained for information on temperature and rainfall, a hundred questionnaires were used to analyze how much anthropogenic activity has contributed to desertification in the area by looking at their socioeconomic activities, roads, and infrastructural development. To determine the quantity, distribution, growth, and yield of all the species, a transect of one square kilometer was surveyed using regional techniques in each of the four cardinal directions. Principal component analysis revealed that the activity variables and activity observations for 1999, 2006, 2016, and 2016 were all negative, while the years 1986 and 2020 were positive. Increased trends in temperature and decreasing trends in rainfall are evident using the Mann-Kendall analysis, with P-values of 0.0 and 0.003, respectively, which are smaller than the alpha value of 0.05. The main causes of drought and desertification vulnerability according to the findings include variations in the characteristics of rainfall, human activities, and overgrazing. More tree-planting initiatives should be encouraged, ideally making them an annual event in the study region.

. Alcoholic liver disease is a common liver disease caused by chronic alcohol consumption and is categorized into fatty liver, alcoholic hepatitis, and alcoholic cirrhosis. This study aimed to examine the relationship between alcoholic liver disease and overweight in older adults, focusing on age and gender differences The study was designed as a retrospective age-matched case-control study using the Chang Gung Research Database (CGRD). The data of this study were collected from January 1, 2018 to December 31, 2022. The subjects were aged over 65 years old with a primary diagnosis of alcoholic liver disease. The experimental group matched gender and age group to conduct a case-control study with a ratio of 1:2 for the control group. The relationship between overweight and alcoholic liver disease was analyzed by logistic regression. The study found that the prevalence of alcoholic liver disease was significantly higher in male than in female. The prevalence of overweight in male with alcoholic liver disease decreased with age distribution. For female, age did not matter much. However, among female aged 65 to 69 years, those who were overweight were more likely to develop alcoholic liver disease than those who were of normal weight. These findings provide guidance for population-specific prevention and treatment strategies and highlight the importance of weight control in aged 65 and over. Particularly in the aging population, attention to weight control and aging, as well as the development of alcoholic liver disease, may improve patient health and quality of life.

. Individuals of 13 lily varieties were treated in artificial climate chambers at a day/night temperature of 25/15 °C as control, and low-temperature at 15/5 °C for 1 day (D 1 ), 3 days (D 2 ), 5 days (D 3 ) respectively, and rewarmed under the control temperature for 2 days (D 4 ) after D 3 treatment. The physiological indexes including electrical conductivity (Rec), osmotic adjustment substance contents of proline (Pro), soluble sugar (SS) and soluble protein (SP), and activity of superoxide dismutase (SOD) were measured. The results showed that the Rec of most varieties increased significantly under 1 day low-temperature stress and then showed a decreasing trend with the extension of stress time. The Pro of all varieties increased significantly under low-temperature stress, but the SP of most varieties decreased significantly. The SS content of more than half of the varieties increased significantly with the extension of low-temperature stress. The SOD activities of all varieties increased and most of them increased significantly under stress. After rewarming, the Rec of 54% of the varieties increased, and 31% increased significantly compared with D 3 . SS contents of about 62% of the varieties and SP contents of about 46% of the varieties increased significantly. Pro contents of 77% of the varieties decreased. The SOD activity of 77% of the varieties increased and 31% of the varieties increased significantly. After comprehensive analysis by the membership function method the cold adaptability of lily varieties showed a descending order as Concad’Or > Tiber > Asopus > Golden Matrlx > Red twin > Willmottiae > Orange Matrlx > Maximowiczii > Viviana Zantriana > Dauricum > Maldano > Robina > Eyeliner. The results of this study provided a theoretical basis for screening suitable lily varieties for gardens in the northeast of China.
。将13个百合品种分别置于25/15℃昼夜温度的人工气候室中，分别在15/5℃低温条件下处理1 D (d1)、3 D (d2)、5 D (d3)， d3处理后在对照温度下再加热2 D (d3)。测定了电导率(Rec)、脯氨酸(Pro)、可溶性糖(SS)、可溶性蛋白(SP)渗透调节物质含量和超氧化物歧化酶(SOD)活性等生理指标。结果表明:大多数品种的Rec在1 d低温胁迫下显著升高，然后随着胁迫时间的延长呈下降趋势;低温胁迫下，各品种的Pro均显著升高，但多数品种的SP显著降低。随着低温胁迫时间的延长，半数以上品种的SS含量显著增加。所有品种的SOD活性均升高，且多数品种在胁迫下显著升高。复温后，54%的品种的Rec增加，其中31%的品种与复温前相比显著增加。约62%的品种SS含量和46%的品种SP含量显著增加。77%的品种Pro含量下降。77%的品种SOD活性显著升高，31%的品种显著升高。通过隶属函数法综合分析，百合品种的冷适应性从大到小依次为:conad 'Or > Tiber > Asopus > Golden matrix > Red twin > willmotiae > Orange matrix > Maximowiczii > Viviana Zantriana > Dauricum > Maldano > Robina > Eyeliner。本研究结果为筛选东北地区园林百合适宜品种提供了理论依据。
