Abstract Asteraceae is the most diverse family of vascular plants in the world and the most numerous in Argentina, with 26% of endemic species. Many Asteraceae are pioneer species facilitating the establishment of other species, and several have been employed in restoration. Knowing the characteristics of seeds and their germination is crucial to employ them in restoration projects; hence this study explored basic physiological aspects of the germination of Gutierrezia solbrigii Cabrera and Senecio subulatus D. Don ex Hook. & Arn. var. erectus Hook. & Arn., two endemic shrubs of Argentina, distributed in arid Patagonia. Seeds came from the Reserva Provincial… More >

Abstract The agave papalote (Agave cupreata Trelease) which is endemic to the Guerrero state, Mexico, is propagated exclusively by seed, but it is overutilized and knowledge of its diversity is needed for its protection. Therefore, the study aimed to determine the morphological variation in wild and cultivated populations of Agave cupreata in five areas of Guerrero. Ninety one characters were evaluated in situ, and only 51 qualitative and quantitative morphological characters of the plant, leaf spine, flower, fruit, seed and flower stalk were selected. The work was carried out in five different altitudinal zones, according to the level of production of… More >

Abstract Seed dormancy release and germination of Corispermum lehmannianum Bunge were tested using various treatments: temperature, cold stratification, gibberelins (GA3), dry storage and sand burial. Results showed that temperature and light did not affect the germination of fresh seeds, cold stratification and GA3 could improve seed germination, whereas dry storage and sand burial did not. The germination percentage was highest at 35/20 °C after the cold stratification and GA3 treatments. Corispermum lehmannianum seeds were classified as non-deep, Type-2, physiological dormancy (PD), whose seed dormancy could be released by cold stratification and GA3. More >

Abstract The search for new anti-inflammatory drugs with fewer side effects than those currently available in the market has recently attracted the interest of scientists. Medicinal plants might be a natural source of medicines. Such is the case with Ziziphus amole (Sessé & Moc.) M.C. Johnst. or corongoro, a plant species native to México. It is used in traditional medicine as an anti-inflammatory drug, a healing substance and an analgesic, and in the treatment of diarrhea, diabetes, asthma and hemorrhoids. The aim of this study was to evaluate the anti-inflammatory effect of Z. amole in the acute 12-O-tetradecanoylphorbol-13-acetate (TPA) induced mouse… More >

Abstract The detection of phenolics, flavonoids and related compounds by HPLC in extracts of unifloral honey of Quillay (Quillaja saponaria) showed phenolic compounds such as caffeic, coumaric and salicylic acids, the flavanone naringenin and the flavonol kaempferol. These extracts showed antibacterial activity against Pseudomonas aureginosa, Escherichia coli, Staphylococcus typhi, S. aureus, Streptococcus pneumoniae type β, and Vibrio cholerae, and antifungal activity against Candida albicans. Additionally, some aroma and decomposition compounds were identified in the ethanol extract. More >

Abstract Artesunate, an antimalarial drug, has been shown to inhibit the release of inflammatory mediators in various disease conditions. The present study was carried out to evaluate the anti-edematogenic effect of artesunate in the rat paw edema model. Inflammation was induced in the hind paw of rat by sub-plantar injection of 0.1 mL of 0.5% carrageenan and the paw volume was measured up to a fixed mark just before the injection and then after 3 h. The difference in two volumes gave a measure of edema formation. At 3h the level of TNF-α, PGE2 and myeloperoxidase were estimated in the inflamed… More >

Abstract Twenty one days old Swiss albino mice that received diphenylhydantoin (25 mg/kg, i.p., daily for 15 days) progressively developed gait alterations, changes of behavior and cerebellar ataxia. Cerebellar slices were processed by conventional transmission electron microscopy. The body of Purkinje cells exhibited fragmented limiting plasma membranes, dilated nuclear envelopes, swelling and disassembly of nuclear pores, enlargement of rough and smooth endoplasmic reticulum and a notable detachment of membrane associated ribosomes, together with distorted vacuoles of smooth endoplasmic reticulum, bizarre shaped and swollen mitochondria with dilated cristae, as well as disrupted limiting lysosomal membranes. Degenerated axosomatic synapses apparently corresponding to basket… More >

Abstract The solid particle impurities generated by pipe wall corrosion might deposit at the elbow of hilly pipelines during the production shutdown of oil pipelines. These solid particle impurities will seriously affect the safety of the pipeline operation and the quality of the petroleum products. Thus, it is necessary to study the methods of removing these trapped particles from pipelines. At present, the most common way to remove these solid particle impurities is pigging oil pipelines periodically by utilizing the mechanical pigging method, while the frequent pigging operation will increase the cost and risk of pipeline operation. It is very convenient… More >

Abstract The Onagraceae are a well-defined family of flowering plants much used by man. Many representatives of this group, which contains 75 species belonging to 8 genera, are indigenous to Argentina, and 19% of these are commonly found throughout the country. Many Onagraceae are ruderal and promote the subsequent establishment of other species, thus contributing to the restoration of degraded areas. Since it is important to know the characteristics of seeds to be used in restoration projects, we studied the basic germination physiology of Oenothera odorata Jacq., a ruderal plant indigenous to Argentina. Material was collected from roadsides and embankments along… More >

Abstract Six mitochondrial (mtDNA) markers, cox2, ccmFn, ccb256, cox3, Nad4L-orf25, and atp4, were combined to assess genetic relationships by using Maximum Likelihood (ML) and Maximum parsimony (MP). This was done among nine Chinese Curcuma herbal species, included two rare species which are difficult to distinguish from their morphological characters. The relationships are very close among the nine species, and the overall distance was 0.018. In this study, the backbone of such nine species was achieved firstly to date, and being divided into two groups with moderate to strong bootstrap support. Both the ML and MP tree were obtained with similarity topologies… More >
