RESUMEN
Genetic diversity among seven Saudi tomato landraces collected from different regions of the country was assessed using SDS-PAGE and molecular (sequence-related amplified polymorphism- SRAP) markers. A total of 19 alternative protein bands with different mobility rates were identified within a molecular weight range of 9.584-225â¯KDa, with 53% polymorphism. Specific protein bands were observed in the "Hail 548" and "Qatif 565" landraces. Genetic similarity based on Jaccard's coefficient ranged from 0.53 to 1.00, with an average of 0.72. For molecular evaluation, 143 amplicons (fragments) were generated using 27 SRAP primer pair combinations, of which 88 were polymorphic across all the landraces. The PIC values ranged from 0.46 to 0.90, with an average of 0.76. All landraces showed an average of 0.66 similarity coefficient value. The UPGMA dendrogram supported by principal coordinate analysis (PCoA) revealed clusters of the landraces that almost corresponded to their geographical origin. Thus, seed storage protein profiling based on SDS-PAGE and SRAP markers can efficiently be used to assess genetic variability among tomato germplasms. The information obtained in the analysis will be of great interest in the management of ex situ collections for utilization in breeding programs or for direct use in quality markets.
RESUMEN
Medical emergencies may occur in any setting, including dermatology offices. We examined the incidence of medical emergencies in a survey of 34 dermatologists northeast Ohio. Fifty-five events occurred over 565 combined years of clinical practice, an incidence of 1 episode every 10.3 years. We also review options for better preparedness for medical emergencies in dermatology practices, ranging from an emergency action plan for emergency personnel, basic life support (BLS) certification, advanced cardiac life support (ACLS) certification, and on-site automatic electronic defibrillators (AEDs).
