Epidemiology of bloodstream infection in Saudi Arabia

Bloodstream infections are a challenge to clinicians due to high rates of morbidity and mortality. Moreover, rational antimicrobial therapy, if promptly started, can improve the prognosis of sepsis. The gold-standard blood culture has some limitations and it takes time to complete (about 2-5 days). This leaves the clinicians to start immediately broad-range antimicrobial therapy until microbiology culture’s...

Influence of cytoplasmic genetic male sterility in the grain yield of maize hybrids

One of the main barriers to the production of hybrid maize seeds consists of needing detasseling of female parent in order to avoid contamination with unwanted pollen. This activity is a laborious practice, which makes the production more expensive and promotes productive losses. Thus, the use of cytoplasmic genetic male sterility can facilitate the hybridization process, and consequently, the production of hybrid...
