Current state of knowledge on the traditional uses, phytochemistry, and pharmacology of the genus Hymenaea.

Ethnopharmacological Relevance: Plants of the genus Hymenaea (Fabaceae) are used in South American and Asian traditional medicines to treat a multitude of disorders, like cough, diarrhea, dysentery, intestinal colic, pulmonary weakness, asthma, anemia, sore throat, and for the treatment of kidney problems, viral related disorders, chronic cystitis, bronchitis, and bladder infections. Some Hymenaea species are also used as vermifuge, and for the treatment of arthritis, and inflammation conditions. This review deals with updated information on the traditional uses, phytochemistry and pharmacology of ethnomedicinally important Hymenaea species in order to provide an input for the future research prospects.

The hydrographic features of anguillid spawning areas: potential signposts for migrating eels.

Catadromous anguillid eels (Genus ) migrate from their freshwater or estuarine habitats to marine spawning areas. Evidence from satellite tagging studies indicates that tropical and temperate eel species exhibit pronounced diel vertical migrations between 150 to 300 m nighttime depths to 600 to 800 m during the day. Collections of eggs and larvae of Japanese eels ( ) show they may spawn at these upper nighttime migration depths.

Does mycorrhization influence herbivore-induced volatile emission in Medicago truncatula?

Symbiosis with mycorrhizal fungi substantially impacts secondary metabolism and defensive traits of colonised plants. In the present study, we investigated the influence of mycorrhization (Glomus intraradices) on inducible indirect defences against herbivores using the model legume Medicago truncatula. Volatile emission by mycorrhizal and non-mycorrhizal plants was measured in reaction to damage inflicted by Spodoptera spp.

Microbial oligosaccharides differentially induce volatiles and signalling components in Medicago truncatula.

Plants perceive biotic stimuli by recognising a multitude of different signalling compounds originating from the interacting organisms. Some of these substances represent pathogen-associated molecular patterns, which act as general elicitors of defence reactions. But also beneficial microorganisms like rhizobia take advantage of compounds structurally related to certain elicitors, i.

Changes in the pattern of substance abuse after the onset of psychosis.

Objective: The aim of this study was to examine early signs of psychosis in patients suffering from both drug dependence and schizophrenia, compared to a control group of drug-addicted patients without a comorbid psychotic disorder, and to assess whether the presence of these signs was related to changes in the pattern of substance abuse.

Method: In a rehabilitation hospital for young addicts, 32 patients with a comorbid diagnosis of schizophrenia and 30 patients without the diagnosis of a psychotic disorder, were assessed using the Interview for the Retrospective Assessment of the Onset of Schizophrenia. Information relating to 64 signs of early psychosis was collected from every patient.

Isospin violation in e+ e- -->BB.

The ratio of the B+ B- and B0B0 production rates in e+ e- annihilation is computed as a function of the B meson velocity and BB*pi coupling constant, using a nonrelativistic effective field theory.

Improved Syntheses and Some Selective Transformations of 2,2,4,4-Tetrachloro-8-oxabicyclo[3.2.1]oct-6-en-3-ones.

The methyl- and alkenyl-substituted furans 1b-h react with pentachloroacetone (2) and sodium 2,2,2-trifluoroethoxide solution to form the title compounds 3b-h in good yield. With the furans 1i-m bearing an oxygen or a sulfur heteroatom in the side chain, moderate yields are obtained. Dechlorination of the [4+3] cycloadducts 3 with the Zn-Cu couple leads to the corresponding oxabicyclic ketones 4.
