Platelet aggregation and bleeding time abnormalities are reported in patients receiving beta-lactam antibiotics (beta LAs), although clinical bleeding most frequently occurs in chronically ill, malnourished patients. Although most beta LAs bind to serum albumin, the relative influence of bound versus unbound beta LAs on platelet function is unknown. We examined the effect of beta LAs on the agg...

Resumen.—Muchas especies de playeros tienen distribuciones amplias que incluyen continentes diferentes. Debido a que los playeros son excelentes voladores y tienen la capacidad de migrar largas distancias, muchas veces no está claro si existen barreras reproductivas entre poblaciones o subespecies de diferentes continentes. Charadrius alexandrinus es una especie cosmopolita. Hace mucho tiempo s...

Anionic surfactants are the most widely exploited chemical surfactants, which are being incorporated into majority of detergents and cleaning products used for household and industrial applications. Linear alkylbenzene sulfonates (LAS) is one of the major xenobiotic anionic surfactants. Biodegradation is an effective process to reduce the amount of surfactants released in the environment. In th...

Candidatus Liberibacter asiaticus "Las" is a phloem-limited bacterial plant pathogen, and the most prevalent species of Liberibacter associated with citrus huanglongbing (HLB), a devastating disease of citrus worldwide. Although, the complete sequence of the Las genome provides the basis for studying functional genomics of Las and molecular mechanisms of Las-plant interactions, the functional c...

Huanglongbing (HLB) is presently the most devastating citrus disease worldwide. As an intracellular plant pathogen and insect symbiont, the HLB bacterium, 'Candidatus Liberibacter asiaticus' (Las), retains the entire flagellum-encoding gene cluster in its significantly reduced genome. Las encodes a flagellin and hook-associated protein (Fla) of 452 amino acids that contains a conserved 22 amino...

Durante los últimos años, la utilización de las inmunoglobulinas endovenosas (Ig ev) se ha extendido desde las inmunodeficiencias primarias, a una serie de entidades clínicas como los procesos infecciosos, las enfermedades neurológicas inflamatorias y las enfermedades autoinmunes. Las Ig ev son una terapia bien tolerada, con pocos efectos adversos, aunque con un elevado coste económico. Aunque ...

Huanglongbing (HLB), considered the most serious citrus disease in the world, is associated with the nonculturable bacterium 'Candidatus Liberibacter asiaticus' (Las). Infection of citrus by this pathogen leads to reduced plant vigor and productivity, ultimately resulting in death of the infected tree. It can take up to two years following initial infection before outward symptoms become appare...

This study investigates how the undergraduate Learning Assistant (LA) experience affects teachers’ first year of teaching. The LA Program provides interested science majors with the opportunity to explore teaching through weekly teaching responsibilities, an introduction to physics education research, and a learning community within the university. Some of these LAs are recruited to secondary s...
