تناولت الدراسة تحليل التباين المكاني للتركيبين العمري والنوعي للسكان وعلاقتهما بنسب الإعالة في إقليم جنوب العراق (البصرة، ذي قار، ميسان، المثنى، القادسية) خلال المدة الزمنية (2000-2025). واعتمدت الدراسة في معالجتها المنهجية على المنهج الوصفي التحليلي والمنهج المقارن، مستندة إلى بيانات مكانية – سكانية. خلُصت الدراسة إلى أن وحدات الإقليم دخلت مرحلة "الهبة الديموغرافية"، ببلوغ متوسط نسبة السكان في سن العمل (15-64 سنة) ما يتجاوز 58.91%. وكشفت النتائج عن تباين مكاني حاد في نسب الإعالة الكلية، إذ سُجلت أعلى القيم في البيئة الريفية الطاردة لمحافظة ميسان (76 معالاً لكل 100 فرد منتج)، بينما انخفضت في محافظتي القادسية (66)معالاً والبصرة (68) معالاً بدلالة تباين الخصائص الاقتصادية والاجتماعية للمكان. وأظهرت الدراسة تأثر التوزيع الجغرافي للتركيب النوعي بحركة الهجرة الداخلية ذات الدوافع البيئية والاقتصادية، حيث ارتفع معامل النوع في مركز الجذب الحضري (البصرة) إلى 103 ذكور لكل 100 أنثى، في مقابل اختلاله في المناطق الطاردة. كما أثبت القياس الإحصائي وجود علاقة ارتباط طردية تامة بين حجم فئة صغار السن ونسبة الإعالة الكلية، في مقابل استقرار مكاني منخفض لنسبة إعالة كبار السن وتراوحها بين 5 و6. وعلى ضوء النتائج، أوصت الدراسة بضرورة تبني سياسة تخطيط مكاني لا مركزية، وتوظيف الفائض البشري الشاب في قطاعات صناعية وزراعية مكانية بديلة عن القطاع النفطي، مع التدخل العاجل بيئياً في المحافظات الطاردة للسكان لكبح أنماط الهجرة البيئية غير المنتظمة.

In several diseases including cancer, abnormal miRNA expression has been linked to apoptosis, proliferation, differentiation, and metastasis. Many miRNAs have been studied in relation to cancer, including miR-122, miR-223, and others. Hepatitis B and C viruses are the most important global risk factors for HCC. This study is intended to test whether serum miRNAs serve as a potential biomarker for both HCC and viral infections HBV and C. The expression of miRNA in 64 serum samples was analyzed by RT-qPCR. Compared to healthy volunteers, HCC patients' sera expre
