Direct discharge of untreated sewage to surface waters is a common practice in many parts of the world. However, relatively little is known about the behaviour of synthetic organic pollutants under these conditions. This paper describes a sampling campaign designed to track changes in water quality in a surface water system in Vientiane (Lao PDR) receiving significant quantities of untreated wa...

Huanglongbing (HLB), also known as citrus greening, is one of the most destructive diseases of citrus worldwide. HLB is associated with three species of 'Candidatus Liberibacter' with 'Ca. L. asiaticus' (Las) being the most widely distributed around the world, and the only species detected in Thailand. To understand the genetic diversity of Las bacteria in Thailand, we evaluated two closely-rel...

OBJECTIVES The goal of this study was to assess the impact of left atrial scarring (LAS) on the outcome of patients undergoing pulmonary vein antrum isolation (PVAI) for atrial fibrillation (AF). BACKGROUND Left atrial scarring may be responsible for both the perpetuation and genesis of AF. METHODS A total of 700 consecutive patients undergoing first-time PVAI were studied. Before ablation,...

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 ...
