In this study, immobilization of partially purified almond (Amygdalus communis) β-galactosidase on Con A layered calcium alginate-cellulose beads was investigated. Immobilized β-galactosidase retained 72% of theinitial activity after crosslinking by glutaraldehyde. Both soluble and immobilized enzyme exhibited the samepH and temperature optima at pH 5.5 and 50ºC, respectively. Howev...

Aqueous extract of Ricinus communis and Lantana camara contains substances that have allelopathic potential on maize (Zea mays L.). The present study showed that different concentrations of the water soluble leaf extracts of R. communis and L. camara inhibit the germination and growth of maize. These extracts also affect activity of some enzymes. Leaf aqueous extracts of both the plants were ma...

Insect parasitoids and herbivores must balance the risk of egg limitation and time limitation in order to maximize reproductive success. Egg and time limitation are mediated by oviposition and egg maturation rates as well as by starvation risk and other determinants of adult lifespan. Here, we assessed egg load and nutritional state in the soybean aphid parasitoid Binodoxys communis under field...

The arbuscular mycorrhizal fungi (AMF) are a key, integral component of the stability, sustainability and functioning of ecosystems. In this study, we characterised the AMF biodiversity in a native vegetation soil and in a soil cultivated with Jatropha curcas or Ricinus communis, in a tropical system in Guantanamo (Cuba), in order to verify if a change of land use to biofuel plant production ha...

OBJECTIVE To determine the clinical features of mosquito allergy in children and the ability of commercially available mosquito allergy tests to detect children with mosquito allergy in Thailand. METHODS Patients with mosquito allergy aged 1 month to 18 years were recruited. Demographic data, history of mosquito allergy (onset of the reaction, reaction type) and clinical features were recorde...

The Palearctic species Amara communis (Panzer) and Bembidion femoratum Sturm were both first reported from North America in 1992. Since that time a sizeable number of additional specimens of both species have been found, which substantially expands their known range on the continent. These records are summarized herein. The possible modes of introduction of both species are discussed within the...

BACKGROUND Juniperus communis L. represents a multi-purpose crop used in the pharmaceutical, food, and cosmetic industry. Several studies present the possible medicinal properties of different Juniperus taxa native to specific geographical area. The present study aims to evaluate the genoprotective, antioxidant, antifungal and anti-inflammatory potential of hydroalcoholic extract of wild-growin...
