Relationship of Nitrogen Deficiency-Induced Leaf Senescence with ROS Generation and ABA Concentration in Rice Flag Leaves
Nitrogen (N) deficiency is one of the critical environmental factors that induce leaf senescence, and its occurrence may cause the shorten leaf photosynthetic period and markedly lowered grain yield. However, the physiological metabolism underlying N deficiency-induced leaf senescence and its relationship with the abscisic acid (ABA) concentration and reactive oxygen species (ROS) burst in leaf tissues are not well understood. In this paper, the effect of N supply on several senescence-related physiological parameters and its relation to the temporal patterns of ABA concentration and ROS accumulation during leaf senescence were investigated using the premature senescence of flag leaf mutant rice (psf) and its wild type under three N treatments. The results showed that N deficiency hastened the initiation and progression of leaf senescence, and this occurrence was closely associated with the upregulated expression of 9-cis-epoxycarotenoiddioxygenase genes (NCEDs) and with the downregulated expression of two ABA 8′-hydroxylase isoform genes (ABA8ox2 and ABA8ox3) under LN treatment. Contrarily, HN supply delayed the initiation and progression of leaf senescence, concurrently with the suppressed ABA biosynthesis and relatively lower level of ABA concentration in leaf tissues. Exogenous ABA incubation enhanced ROS generation and MDA accumulation in a dose-dependent manner, but it decreased the activities of glutamine synthetase (GS) and glutamate dehydrogenase (GDH) in detached leaf. These results suggested that the participation of ABA in the regulation of ROS generation and N assimilating/remobilizing metabolism in rice leaves was strongly responsible for induction of leaf senescence by N deficiency.

Deep Learning-Based Change Detection in Remote Sensing Images: A Review
Images gathered from different satellites are vastly available these days due to the fast development of remote sensing (RS) technology. These images significantly enhance the data sources of change detection (CD). CD is a technique of recognizing the dissimilarities in the images acquired at distinct intervals and are used for numerous applications, such as urban area development, disaster management, land cover object identification, etc. In recent years, deep learning (DL) techniques have been used tremendously in change detection processes, where it has achieved great success because of their practical applications. Some researchers have even claimed that DL approaches outperform traditional approaches and enhance change detection accuracy. Therefore, this review focuses on deep learning techniques, such as supervised, unsupervised, and semi-supervised for different change detection datasets, such as SAR, multispectral, hyperspectral, VHR, and heterogeneous images, and their advantages and disadvantages will be highlighted. In the end, some significant challenges are discussed to understand the context of improvements in change detection datasets and deep learning models. Overall, this review will be beneficial for the future development of CD methods.

الإسلام على مفترق الطرق
مؤلف هذا الكتاب صارح المسلمين بحقائق قل أن جرؤ غيره على التصريح بها : إنه درس دقيق لحال المسلمين اليوم من الناحية الثقافية والروحية. وهو يدعو المسلمين إلى العودة إلى حقيقة دينهم، لأن الدين الذي استطاع أن يجمع العرب منذ أربعة عشر قرنا، ويجعل منهم قوة عظيمة في السياسة والعلم والاجتماع يستطيع أن يقدم لهم اليوم ما قدم بالأمس : دستورا للحياة لا يجدون مثله في النظم التي تعرضت منذ فجر التاريخ حتى اليوم لتهذيب البشر.
Senescence‐related translocation of nonstructural carbohydrate in rice leaf sheaths under different nitrogen supply
The translocation of nonstructural carbohydrates (NSC) from leaf sheaths to filling grains after anthesis contributed greatly to the grain yield of cereal crops. In this study, the effect of nitrogen (N) supply levels on the accumulation and translocation of NSC in leaf sheath tissues and its relationship with the initiation and progression of leaf senescence during grain filling was investigated using two rice (Oryza sativa L.) genotypes, namely, premature flag leaf senescence mutant (psf) and its wild‐type. Three N treatment levels were used to examine N‐supply induced alteration in the activities of several key enzymes involved in NSC translocation and N assimilation in different leaf sheaths. The results show that the NSC translocation rate in leaf sheaths under low nitrogen (LN) treatment was significantly higher than those under normal nitrogen (NN) and high nitrogen (HN) treatments. However, the positive effect of LN on the NSC translocation in leaf sheath was closely associated with its negative effect on grain yield, due to accelerated leaf senescence and shortened leaf longevity. Comparatively, the upper‐positional sheath had a lower NSC amount and higher NSC translocation rate than the lower‐leaf sheaths after heading. High N suppressed sucrose‐phosphate synthase (SPS) activity in leaf sheaths, but enhanced the activity of key enzymes involving in N assimilation in leaf sheaths. The upper sheath had higher activity of sucrose‐metabolizing enzymes and lower activity of N‐assimilating enzymes. Hence, the upper‐leaf sheath had a relatively weak N assimilation and stronger NSC translocation than the lower‐leaf sheaths.

Racialized vulnerability and socioeconomic determinants of health among Afghan refugees in Pakistan
Afghan refugees face persistent poverty, social marginalization, and restricted access to healthcare in Pakistan, making them one of the world’s largest and longest-displaced groups. Health disparities have been made worse by decades of instability, especially among marginalized groups living in informal urban settlements and refugee camps. With an emphasis on how income, education, and legal status affect health outcomes and healthcare access, this study explores the socioeconomic determinants and health burdens among Afghan refugees residing in Pakistan. Between January and June 2025, 250 Afghan refugee families (n = 1460 people) in the provinces of Balochistan and Khyber Pakhtunkhwa were surveyed. To guarantee proportionate representation from camp-based and urban populations, stratified random sampling was employed. Data were gathered via structured questionnaires using a cross-sectional methodology, and SPSS v.27 was used for analysis. Multiple logistic regression, chi-square tests, and descriptive statistics were used to find predictors of poor health outcomes. Undocumented status (OR = 3.11, p < 0.001) and low income (OR = 2.34, p < 0.001) were found to be significant risk variables. Results show that poor health outcomes are strongly correlated with socioeconomic deprivation. Reducing health disparities among Afghan refugees in Pakistan requires bolstering social protection systems, livelihood initiatives, and inclusive healthcare access.
