Borrelia infection in Ixodes pararicinus ticks (Acari: Ixodidae) from northwestern Argentina by Nava, Santiago, Barbieri, Amália Regina Mar, Maya, Leticia, Colina, Rodney, Mangold, Atilio Jose, Labruna, Marcelo B., Venzal, José Manuel

“…Also, this genospecies is closely related to two genospecies known from USA, Borrelia americana and the Borrelia sp. genospecies 1. The epidemiological risk that implies the infection with Borrelia in I. paracinus ticks from Argentina appears to be low because the genospecies detected is not suspected of having clinical relevance and there are no records of Ixodes ticks biting humans in the southern cone of South America. …”

Anthocyanins and their effects on blood pressure by Christerson, Martina

“…The aim of this literature review was to investigate the scientific evidence for potential beneficial effects of anthocyanins on hypertension and identify possible mechanisms for such effects. Long term epidemiological studies indicate that anthocyanins do have positive effects on blood pressure as well as maintaining normal vascular function. …”

Quantification of the components of resistance to rice sheath blight using a detached tiller test under controlled conditions by Willocquet, Laetitia, Lore, Jagjeet S., Srinivasachary, S., Savary, Serge

“…Resistance of rice (Oryza sativa) to sheath blight, caused by Rhizoctonia solani, is quantitative and involves two mechanisms: physiological resistance and disease escape. The epidemiological concept of components of resistance was applied using a detached tiller method under controlled conditions, to specifically address physiological resistance to sheath blight in rice. …”
