Genetic Diversity Analysis of Forty Pearl Millet (<i>Pennisetum glaucum</i>(L.) R. Br) Accessions from Sudan Using Agronomical Descriptors and DNA Molecular Markers

引用

Advances in Bioscience and Biotechnology 2018年第7期9卷 322-337页

作者： Hanaa ibrahim Mohammed nada Babiker Hamza Agricultural Research Corporation Biotechnology and Biosafety Research Center Khartoum Sudan Commission for Biotechnology & Genetic Engineering National Center for Research Khartoum Sudan

Morphological descriptors and Random Amplification of Polymorphic DNA (RAPD) technique were used to assess the genetic variation among and within forty Pennesitum glaucum accessions from Sudan. Accessions were collected from 30 villages representing Darfur, North Kordofan, South Kordofan, and Blue Nile states. 64 amplified fragments were distinguished using ten primers.? 63 bands were polymorphic among the forty accessions with an average of 6.3 polymorphic bands per primer. Low level of genetic similarity was observed (4% - 43%). The PhiPT (analogue of FST fixation index) value for genetic variability obtained over the four regions was 0.169 with high significance (P = 0.01). AMOVA analysis showed higher variance components within regions (80%) than among regions (20%). The two dendrograms obtained by Random Amplification of Polymorphic DNA (RAPD) data;and morphological data based on 26 descriptors did not fit together. PCA (Principal coordinate’s analysis) showed geographic structuring of pearl millet according to its growing regions in Sudan.

Effect of Pre-Existing Chronic Medical Conditions on Clinical Features and Disease Outcomes of COVID-19 Infection in Jordanian Children

引用

Journal of Biosciences and Medicines 2023年第12期11卷 275-286页

作者： Katrel-nada AlAlawneh Ruaa ibrahim Qasim Mhaidat Mohammad Suliman Ahmad Rababah Hajar Ayasreh Eyad Altamimi Department of Pediatric Faculty of Medicine Jordan University of Science and Technology Irbid Jordan Faculty of Medicine Jordan University of Science and Technology Irbid Jordan

Background: The COVID-19 pandemic emerged unexpectedly, impacting millions worldwide and, though waning in many regions, remains a significant concern. This study focused on understanding COVID-19’s clinical presentation, disease progression, and outcomes among hospitalized pediatric patients. Additionally, it sought to investigate the impact of concurrent chronic medical conditions on disease severity. Methods: Conducted retrospectively between September 2020 and December 2021, this study observed pediatric patients (below 18 years) hospitalized with confirmed COVID-19 at an Irbid, Jordan tertiary healthcare center. Patients meeting inclusion criteria, including a positive nasal swab PCR test and hospitalization need, were analyzed. Epidemiological and clinical data were collected and segregated into two groups (A and B) based on the presence of chronic conditions. Comparative analysis encompassed presentation, disease trajectory, and outcomes between these groups. Results: Among 451 tested positive patients, 112 were included in the study. Significant differences emerged between the two pediatric groups hospitalized for COVID-19. Those with concurrent chronic illnesses exhibited heightened symptom severity—fever, dyspnea, fatigue—and a higher incidence of abnormal chest radiographs, often requiring intensive care and experiencing elevated mortality rates. Conclusion: This study underscores the criticality of prioritizing COVID-19 management strategies for pediatric patients with pre-existing chronic medical conditions. The findings highlight the increased vulnerability and poorer outcomes experienced by this subgroup, emphasizing the necessity for tailored interventions and focused care approaches.
