Pre-Eocene Synmetamorphic Structure in the Mindoro-Romblon-Palawan Area, West Philippines, and implications for the history of southeast Asia

International audienceThe structure of the pre-Eocene rocks, considered as the "basement" of the Philippines, has been investigated in the Mindoro-Lubang, Romblon-Tablas-Sibuyan, and North Palawan areas. In the former two areas the same pre-Eocene succession of units is recognized from top to bottom: (1) a pre-Eocene olistostrome; (2) an ophiolitic nappe; (3) a schistose sequence (pelites, sandstones, basic schists and marbles); and (4) a gneissic unit. The nature of the contact between the olistostrome and the underlying units is unclear, but the ophiolite and the schistose sequence form two thrust sheets of oceanic origin thrust upon the gneissic unit that is considered a part of a continental basement called the West Philippines Block. Small-scale structures show that the early deformation stage is characterized by a submeridian (0°-N40°E) lineation formed in greenschist to amphibolite facies conditions during the thrusting. Kinematic analysis show that the thrusting was from north to south. In North Palawan, metamorphic rocks with similar microtectonic and kinematic characteristics are found. They are overlain by a Late Jurassic olistostrome which is correlated with the olistostromes found in Calamian, North Mindoro, Carabao, and Buruanga peninsula (North Panay). The microstructural features and the presence of the olistostrome suggest that the North Palawan, Mindoro, Tablas, Romblon, Sibuyan, and Carabao islands belong to the same North Palawan block of Hamilton (1979) which is a continental fragment rifted from Asia in Cenozoic times. It is assumed that the Western Panay and Zamboanga areas, which are characterized by Mesozoic ophiolites and metamorphic rocks, also belong to the North Palawan Block. All these islands experienced, to some extent, the same Mesozoic geohistory: the south verging thrusting is interpreted as the result of an oblique collision of the West Philippines Block with Asia. The contemporaneous left-lateral strike-slip faulting and the calc-alkaline magmatism widespread along the Chinese margin are also included in the geodynamic model

Effects of curzerene and Smyrnium cordifolium Boiss. extract on addiction withdrawal syndrome in mice

Introduction: The purpose of this study was evaluating the effect of Smyrnium cordifolium extract (SCE) and curzerene (Cur) on withdrawal syndrome in mice compared with clonidine. Methods: High-performance liquid chromatography (HPLC) was used to determine the active ingredients of S. cordifolium. To evaluate the effects of SCE and Cur, 64 mice were divided into 8 equal groups. Groups 1, 2 and 3 were treated Cur (0.03, 0.06, 0.12 mg/kg, respectively). Groups 4, 5 and 6 were treated with SCE (100, 200, 300 mg/kg, respectively). The seventh group received just morphine. Group 8 received morphine and clonidine (0.2 mg/kg). Results: The results of this study showed that Cur was the most important ingredient in the extract of the plant, and the hydroalcoholic extract yield of S. cordifolium was 17.55% (w/w). The dose of 100 mg/kg of extract (SCE100) and 0.03 mg/kg curzerene (Cur1) (P < 0.05), dose of 200 mg/kg of extract (SCE200) and dose of 0.06 mg/kg curzerene (Cur2), (P < 0.01), dose of 300 mg/kg of extract (SCE300) and dose of 0.12 mg/kg of curzerene (Cur3) (P < 0.001) decreased the symptoms compared to clonidine. Doses higher than 300 mg/kg of extract and 0.12 mg/kg of Cur had fatal effects. All doses of SCE and Cur in comparison with the control group at significant level (P < 0.001) reduced the number of jumping, rearing and teeth chattering in morphine-dependent mice. Conclusion: The findings suggest that SCE and Cur are capable of reducing the symptoms of withdrawal syndrome and their effectiveness may be more than clonidine in reducing the addiction withdrawal syndrome, which may have human therapeutic potential
