Understanding the impact of climate warming on crop yield and its associated mechanisms is paramount for ensuring food security. Here, we conduct a thorough analysis of the impact of vapor pressure deficit (VPD) on maize yield, leveraging a rich dataset comprising temporal and spatial observations spanning 40 years across 31 maize-growing locations in Northeast and North China. Our investigation extends to the influencing meteorological factors that drive changes in VPD during the maize growing phase. Regression analysis reveals a linear negative relationship between VPD and maize yield, demonstrating diverse spatiotemporal characteristics. Spatially, maize yield exhibits higher sensitivity to VPD in Northeast China (NEC), despite the higher VPD levels in North China Plain (NCP). The opposite patterns reveal that high VPD not invariably lead to detrimental yield impacts. Temporal analysis sheds light on an upward trend in VPD, with values of 0.05 and 0.02 kPa/10yr, accompanied by significant abrupt changes around 1996 in NEC and 2006 in NCP, respectively. These temporal shifts contribute to the heightened sensitivity of maize yield in both regions. Importantly, we emphasize the need to pay closer attention to the substantial the impact of actual vapor pressure on abrupt VPD changes during the maize growing phase, particularly in the context of ongoing climate warming.

The purpose of this study is to understand a physical mechanism to determine the surface temperature of clothes in calm and fine conditions of outdoors. We observed surface temperatures of polo shirts of the same material and design but different colors. The shirts were placed in unshaded and well-ventilated outdoor, open spaces on sunny summer days. The maximum difference between dark green or black and white was more than 15 °C during calm, fine weather and was greatest when the solar radiation was strong. If the transmission of solar radiation energy through a shirt is ignored to calculate the absorption by the shirt, the difference in solar radiation absorption due to different colors is as much as 24% in the maximum, and if considered, we concluded that an absorption difference of 34% led to a temperature difference of 15℃. When we compared the brightness of the colors, we found that the albedo of both the visible and NIR bands explained why the red and green colors were so different with respect to the surface temperatures we observed. The reflection in the NIR bands was also an important determinant of the surface temperature. An additional experiment using masks showed that the temperature difference between white and black was almost eliminated at a wind speed of ~ 3 m/s. The color of clothing is therefore a target for small-scale adaptation to climate change.
本研究的目的是了解在平静和晴朗的户外条件下确定衣服表面温度的物理机制。我们观察了材质和设计相同但颜色不同的 Polo 衫的表面温度。在阳光明媚的夏日,这些衬衫被放置在无遮挡、通风良好的室外空地上。在天气晴朗、风平浪静时,深绿色或黑色与白色之间的最大温差超过 15 °C,在太阳辐射强烈时温差最大。如果忽略太阳辐射能量通过衬衫的传输来计算衬衫的吸收,不同颜色对太阳辐射的吸收差异最大可达 24%,如果考虑到这一点,我们得出的结论是,34% 的吸收差异会导致 15℃的温差。当我们比较各种颜色的亮度时,我们发现可见光和近红外波段的反照率解释了为什么红色和绿色与我们观测到的表面温度如此不同。近红外波段的反射也是决定表面温度的一个重要因素。使用面罩进行的另一项实验表明,在风速约为 3 米/秒时,白色和黑色之间的温度差异几乎消失。因此,衣服的颜色是小规模适应气候变化的一个目标。

Urban street dust (UStD) is a vital issue for human health and is crucial for urban sustainability. This study aims to enhance the creation of safe, affordable, and resilient cities by examining environmental contamination and health risks in urban residential areas. Specifically, it investigates the concentrations and spatial distribution of chromium (Cr), cadmium (Cd), nickel (Ni), copper (Cu), lead (Pb), and zinc (Zn) in UStD in Yenimahalle, Ankara. The mean concentrations of Zn, Cr, Pb, Cd, Ni, and Cu in UStD were 97.98, 66.88, 55.22, 52.45, 38.37, and 3.81 mg/kg, respectively. The geoaccumulation pollution index (Igeo) values for these elements were: Cd (5.12), Ni (1.61), Cr (1.21), Pb (1.13), Cu (0.78), and Zn (0.24). These indices indicate that the area is moderately polluted with Cr, Pb, and Ni, uncontaminated to moderately contaminated with Cu and Zn, and extremely polluted with Cd. The hazard index (HI) values for Cr, Cd, Ni, Cu, Pb, and Zn were below the non-carcinogenic risk threshold for adults, indicating no significant risk. However, for children, the HI values for Pb, Ni, Cd, and Zn were 3.37, 1.80, 1.25, and 1.25, respectively, suggesting a higher risk. Carcinogenic risk (RI) of Cd, Ni, and Pb was significant for both children and adults, indicating that exposure through ingestion, inhalation, and dermal contact is hazardous. The findings highlight the need for strategic mitigation measures for both natural and anthropogenic activities, providing essential insights for residents, policymakers, stakeholders, and urban planners.

The objective of this study was to compare the impact of peloid and low-level laser (LLLT) treatment in conjunction with a home exercise programme on short-term symptomatic pain, functional status and quality of life in individuals diagnosed with subacromial impingement syndrome (SIS). A total of 168 patients diagnosed with SIS were included in the study, with 56 receiving LLLT + exercise, 56 receiving peloidotherapy + exercise, and 56 receiving exercise only. Patients underwent clinical evaluations prior to treatment (first measurement), after treatment completion (second measurement), and one month post-treatment (third measurement). Pain was evaluated using the Visual Analog Scale (VAS). Functional status was evaluated using the Shoulder Pain and Disability Index (SPADI), and quality of life was evaluated using the Short Form 36 (SF-36). Active range of motion of the shoulder was measured by the same investigator using a goniometer. Statistically significant improvements in VAS, SPADI, SF-36, and ROM parameters were achieved after treatment and at 1 month follow-up compared to pretreatment in both active treatment groups (p < .05). The third group showed significant improvements in ROM and SF-36 physical components after treatment and 1 month later (p < .05). Low-level laser therapy or peloid therapy given in addition to home exercise therapy for SIS were found to have similar short-term effects on pain, functional status, quality of life and ROM.

Characterization of crop-growing environments in relation to crop's genotypic performance is crucial to harness positive genotype-by-environment interactions (GEI) in systematic breeding programs. Given that, the study aimed to delineate the impact of diverse environments on crop phenology and yield traits of dwarf-statured field pea, pinpointing location(s) favoring higher yield and distinctiveness within breeding lines. We tested twelve field pea breeding lines across twenty locations in India, covering Central Zone (CZ), North Western Plain Zone (NWPZ), North Eastern Plain Zone (NEPZ), and Northern Hill Zone (NHZ). Across these locations, maximum and minimum temperatures during flowering (TMAXF, TMINF) and reproductive period (TMAXRP, TMINRP) ranged 18.9-28.3, 3.3-18.0, 15.0-30.8, and 7.9-22.1oC, respectively. Meanwhile, notable variations in phenological and agronomic traits (coefficient of variation) were observed: flowering (31%), days to maturity (21%), reproductive period (18%), grain yield (48%), and 100-seed weight (18%). Combined ANOVA demonstrated an oversized impact of environment (81%) on yield, while genotype and GEI effects were 2% and 14%, respectively. The variables TMINF, TMINRP, and cumulative growing degree-day showed positive correlations with yield, while extended vegetative and maturity durations negatively influenced yield (p < 0.05). Additionally, linear mixed-models and PCA results explained that instability in crop phenology had significant influence on field pea yield. Seed weight was markedly varied within the locations (9.9-20.8 g) and both higher and lower seed weights were associated with lower yields (Optimal = 17.1 g). HA-GGE biplot-based on environment focus-scaling demonstrated three mega-environments and specific locations viz. Kota (CZ), SK Nagar (CZ), Raipur (CZ), Sehore (CZ), and Pantnagar (NWPZ) as the ideal testing-environments with high efficiency in selecting new genotypes with wider adaptability. The study findings highlight distinct impact of environments on crop phenology and agronomic traits of field pea (dwarf-type), hold substantial value in designing efficient field pea (dwarf-type) breeding program at mega-environment scale.

Mud therapy is a safe, cost-effective approach for Knee Osteoarthritis (OA), promoting healing through warmth and minerals, providing pain relief, and improving function. The main objective of the current review is to assess the effectiveness of local mud application for pain management in patients with Knee OA. The published papers were obtained from PubMed, Embase, Scopus, Cochrane Library, ClinicalTrails.gov, Web of Science, and references from relevant systematic reviews from 1990 January to February 2023. Trials meeting the predefined criteria were included in this meta-analysis. The main focus of this study was to assess pain as a primary outcome measure. R software version 4.3.1 and Cochrane Risk of Bias Tool 1 were used to derive meta-analysis and risk of bias in the included studies. A meta-analysis was performed using the fixed-effects model to obtain a summary of treatment effects, which calculated the effect size (standardized mean difference; SMD) along with a 95% Confidence Interval (CI).In the current meta-analysis, a total of ten studies with 560 Knee OA patients were included. Findings demonstrated significant effects of local mud application on pain (SMD: -0.36, 95% CI: -0.56, -0.16), and the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) scale (SMD: -0.49, 95% CI: -0.68, -0.29) for individuals suffering from Knee OA. The current study identified compelling evidence to support the recommendation of mud application as an effective intervention for individuals with Knee OA. While local mud application may serve as a supplementary therapy alongside conventional medical approaches for improved Knee OA management, additional high-quality randomized controlled trials are required to validate these findings.
泥疗是治疗膝关节骨性关节炎(OA)的一种安全、经济有效的方法,可通过温热和矿物质促进愈合,缓解疼痛并改善功能。本综述的主要目的是评估局部涂泥对膝关节 OA 患者疼痛治疗的有效性。发表的论文来自 PubMed、Embase、Scopus、Cochrane Library、ClinicalTrails.gov、Web of Science,以及 1990 年 1 月至 2023 年 2 月期间相关系统综述的参考文献。符合预定标准的试验被纳入本次荟萃分析。本研究的重点是将疼痛作为主要结果进行评估。使用 R 软件 4.3.1 版和 Cochrane Risk of Bias Tool 1 对纳入的研究进行荟萃分析并得出偏倚风险。本次荟萃分析共纳入了 10 项研究,560 名膝 OA 患者。研究结果表明,局部敷泥对膝关节 OA 患者的疼痛(SMD:-0.36,95% CI:-0.56,-0.16)和西安大略和麦克马斯特大学骨关节炎指数(WOMAC)量表(SMD:-0.49,95% CI:-0.68,-0.29)有明显效果。目前的研究发现了令人信服的证据,支持将泥浆涂抹作为对膝关节 OA 患者进行有效干预的建议。虽然局部敷泥可作为一种辅助疗法,与传统医疗方法一起改善膝关节OA管理,但还需要更多高质量的随机对照试验来验证这些研究结果。

The objective of this study is to explore how changes in weather contribute to an increase in hospital admissions for stroke in summer. We collected 96,509 cases of stroke hospitalization data in Tianjin from 2016 to 2022 summer, along with corresponding meteorological data. The generalized additive model and distributed lag nonlinear model were used to analyze the lag and cumulative effects of temperature on stroke hospitalization. The research results show both the cold effect and the heat effect in summer would increase the risk of hospitalization. The effect of daily maximum temperature on stroke hospitalization was immediate when the temperature was higher, and delayed when the temperature was lower. However, the risk of stroke hospitalization increased more significantly with increasing temperature than with decreasing temperature. In the presence of one or more of the following three weather changes: sharp temperature increase, sharp temperature decrease, continuous high temperature, the daily number of stroke inpatients were higher than the average in the same period. 83% of the Inpatient-heavy events within the study period were caused by a combination of dramatic temperature changes and continuous high temperatures. In 48% of Inpatient-heavy events, continuous high temperature weather above 30℃ for at least 4 consecutive days were observed. And 55% of high temperature weather was accompanied by high humidity. When the daily relative humidity was greater than 70% and the daily maximum temperature was between 26 and 28℃ or more than 34℃, or the daily maximum temperature changes over 10℃ within 48 h, the number of daily inpatients was more than 1.2 times of the average daily inpatients. More attention should be paid to the combined effects of continuous high temperature and sudden temperature changes in summer stroke prevention.

We collected 96,509 cases of stroke hospitalization data in Tianjin from 2016 to 2022 summer, along with corresponding meteorological data. The generalized additive model and distributed lag nonlinear model were used to analyze the lag and cumulative effects of temperature on stroke hospitalization. The research results show both the cold effect and the heat effect in summer would increase the risk of hospitalization. The effect of daily maximum temperature on stroke hospitalization was immediate when the temperature was higher, and delayed when the temperature was lower. However, the risk of stroke hospitalization increased more significantly with increasing temperature than with decreasing temperature. In the presence of one or more of the following three weather changes: sharp temperature increase, sharp temperature decrease, continuous high temperature, the daily number of stroke inpatients were higher than the average in the same period. 83% of the Inpatient-heavy events within the study period were caused by a combination of dramatic temperature changes and continuous high temperatures. In 48% of Inpatient-heavy events, continuous high temperature weather above 30℃ for at least 4 consecutive days were observed. And 55% of high temperature weather was accompanied by high humidity.

Background: PM2.5 has been associated with various adverse health effects, particularly affecting lung function and chronic respiratory diseases. However, the genetic causality relationship between PM2.5 exposure and lung function as well as chronic respiratory diseases remains poorly understood.
Method: We conducted a two-sample Mendelian randomization analysis to investigate the causal impact of PM2.5 on lung function and chronic respiratory diseases. Instrumental variables were carefully selected, with significance thresholds (P < 5 × 10- 8), and linkage disequilibrium with an r2 value below 0.001. Additionally, SNPs with an F-statistic exceeding 10 were included to mitigate potential bias stemming from weak instrumental variables. The primary analytical approach employed the Inverse Variance Weighted method, supplemented by the Weighted Median, MR-Egger, Simple Model, and Weighted Model. Furthermore, pleiotropy and heterogeneity were evaluated through the MR-Egger intercept test and Cochrane's Q test, with a sensitivity analysis conducted using the leave-one-out method.
Results: Eight SNPs significantly associated with PM2.5 exposure were identified as Instrumental variables. Mendelian randomization analysis revealed a significant causal association between PM2.5 exposure and lung function (FEV), with an OR of 0.7284 (95% CI: 0.5799-0.9150). Similarly, PM2.5 exposure demonstrated a substantial causal effect on asthma, with an OR of 1.5280 (95% CI: 1.0470-2.2299). However, no causal association was observed between PM2.5 exposure and chronic obstructive pulmonary disease, with an OR of 1.5176 (95% CI: 0.8294-2.7768).
Conclusion: These findings emphasize the necessity for continued research efforts in environmental health to develop effective strategies for the prevention and management of chronic respiratory diseases.

This study assessed the links between daily mean temperature and emergency room (ER) admissions for total and cause-specific cardiovascular diseases (CVD) in Lanzhou, China from 2013 to 2019. A quasi-Poisson Generalized Additive Model (GAM) and a Distributed Lag Non-Linear Model (DLNM) were used to determine the effects of temperature on total and cause-specific cardiovascular emergency visits. The relative risks (RR) at cold (hot) temperatures were calculated by comparing the 5th (95th) centile of temperature with the minimum morbidity temperature (MMT). Exposure-response curves demonstrating an inverted U-shape or an irregular M-shape association were observed between temperature and total and cause-specific CVD. The study found that both cold and hot temperatures had negative impacts on emergency room visits for various cardiovascular diseases. For people with total CVD, heart rhythm disturbances (HRD), or cerebrovascular diseases (CD), females were more sensitive to temperature than males, while for ischemic heart disease (IHD) and heart failure (HF), males were more vulnerable to temperature. The < 65 years old with total CVD, IHD, HRD, or CD was more susceptible to the effects of temperature. The results indicated that the relationship between temperature and total and cause-specific CVD was nonlinear, and susceptibility to temperature varied across disease subtype, gender, and age.
本研究评估了2013年至2019年期间中国兰州日平均气温与心血管疾病(CVD)总数和特定病因急诊室(ER)入院人数之间的联系。研究采用准泊松广义相加模型(GAM)和分布式滞后非线性模型(DLNM)来确定温度对心血管疾病总门急诊量和特定病因门急诊量的影响。通过比较温度的第 5(95)百分位数与最低发病温度(MMT),计算出冷(热)温度下的相对风险(RR)。温度与总心血管疾病和特定病因心血管疾病之间的暴露-反应曲线呈倒 U 型或不规则 M 型。研究发现,低温和高温都会对各种心血管疾病的急诊就诊率产生负面影响。对于总体心血管疾病、心律紊乱(HRD)或脑血管疾病(CD)患者来说,女性比男性对温度更敏感,而对于缺血性心脏病(IHD)和心力衰竭(HF)患者来说,男性更容易受到温度的影响。温度

The intensity and frequency of climate extremes such as heat waves, droughts and extreme rainfall events are projected to rise. This will increase the severity of their impacts across socio-ecological systems. Economic sectors such as nature-based tourism become more vulnerable because of their reliance on climate and natural capital as key resources. While attempts have been made to understand how climate change may impact tourists and the industry itself, little is known about the same on tourism-dependent communities. This paper determines the extent to which tourism-dependent communities are vulnerable to climate change in the Okavango Delta, Botswana, to enhance their wider livelihood the development of strategies for improving adaptive capacity, resilience, and reduced exposure sensitivities. A household survey of 172 households was conducted in three purposively selected villages of Mababe, Sankuyo and Khwai, actively involved in community-based tourism for their socio-economic development. Information sourced related to livelihood options, peoples' resilience, local risks, and hazards. The data was analysed using descriptive statistics and thematic analysis. The results indicate that respondents have observed climatic changes over the years such as increased temperatures, decreased rainfall, and increased frequencies of extreme events. The respondents attributed changes in natural capital to these observed climatic conditions in the form of desiccation, dwindling populations of some wildlife species, decreased fish stocks and reduced vegetation cover. This renders the tourism-dependent communities vulnerable as their livelihood is threatened. The paper thus concludes that climate change adaptation is an urgent priority for local communities who are already exposed to existing climatic and non-climatic stresses.
