the Kuril islands constitute a volcanic island arc-trench system, stretching from eastern Hokkaido （Japan） to Kamchatka （Russia） along the northwestern Pacific subduction system, the current arc consists of several volcanic islands mainly with neogene basement and capped by several, predominantly andesitic, active subduction stratovolcanoes, Kunashir Island is the southwestern-most island of the arc, just off the Hokkaido coast and represents the study area in this paper. the island is composed of a Lower Complex of mainly late Miocene to Pliocene volcanic rocks, covered by an Upper Complex of younger （basaltic） andesitic lava flows and tuffs on which currently four active volcanic edifices are built. In the Lower Complex sub-volcanic and deeper-seated intrusives of the so-called Prasolov and Dokuchaev magmatic complexes are found, More differentiated, tonalitic-granodioritic rocks were collected from these small intrusive bodies. An early Oligocene zircon LA-ICP-Ms U/Pb age of 31 Ma for the Prasolov Complex was obtained, showing that the basement of Kunashir Island is older than previously thought. thermochronometry （apatite fission-track and U-th-sm/He and zircon U-thJHe analyses） further shows that the magmatic basement of the island was rapidly exhumed in the Pleistocene to present levels in a differential pattern, with He-ages ranging from 1.9 to 0.8 Ma. It is shown that the northern section of the island was hereby exhumed more intensely.

the trace elements characteristics of the migmatitic gneisses (biotite-garnetand hornblende-biotite), granulite facies rocks (charnockitic gneisses) and meta-peridotite in the area of southwest Obudu Plateau indicate that the area exhibits a high degree of geochemical variability. Compatible trace elements (ni and Cr) are comparatively high in the granulite facies rocks and meta-peridotite. ni ranges from 28×10-6 to 266×10-6 whilst Cr ranges from 62×10-6 to 481×10-6 for the granulite facies rocks (charnockitic gneisses), and for the meta-peridotite ni varies between 2045×10-6 and 2060×10-6. Incompatible trace elements show a higher variability in these rocks. the rocks in the area of southwest Obudu Plateau generally are characterized by the high concentrations of Ba, Ce, sr, Rb, Ga, ni, Cr, Co, Zr, Pr and moderate concentrations of Cu, sm and th. the available data show that the charnockitic gneisses are of lower crustal origin. the enrichment of the meta-peridotite in compatible trace elements suggests the primitive mantle would be the source region, with slight contamination during ascent. these diverse origins collaborate the tectonic setting of the area as shown by discrimination diagrams. the diverse tectonic settings range from arc to collisional. Alkaline to sub-alkaline magmatism in the area was probably contemporaneous with the tectonic events that occurred in the area during the Proterozoic.

Pythiosis is an invasive, ulcerative, pyogranulomatous disease caused by Pythium insidiosum, a fungus-like oomycete that has been reported to affect humans, horses, dogs, and other mammals mainly in tropical and subtropical areas of the world. the disease is characterized by an eosinophilic granulomatous and a th2 immune response which in turn helps to protect the fungus from the host cells. Pythiosis can present clinically in subcutaneous, gastrointestinal, and vascular tissues or in a systemically disseminated form depending on the species and site of infection. Changes in iron metabolism and anemia are commonly observed. the diagnosis is accomplished through clinical and pathological features, laboratory characteristics of cultures, serological and molecular tests. Treatment includes radical surgery, antimicrobial drugs, immunotherapy or a combination of these treatments. Immunotherapy is a practical and non-invasive alternative for treating pythiosis which is believed to promote a switch from a th2 to th1 immune response, resulting in a favorableclinical response. this therapy has demonstrated cure rates above 70% and 55% in horses and humans but low cure rates in dogs and cats. Despite the curative properties of this type of immunotherapy, the antibodies that are produced do not prevent host reinfection. thus, development of effective adjuvants and new diagnostic techniques for early disease diagnosis are of utmost importance. the aim of this review was to promote pythiosis awareness and to provide an update about the immunotherapy and immunobiology of this disease.

Lamouroux, Hypnea sp., Cystoseira sp. and Posidonia oceanica (L.) Delile (seagrass) collected from 3 stations along the Mediterranean sea coast of Egypt were determined using instrumental neutron activation analysis. the contents of elements in marine macrophytes indicated that they accumulated elements at different levels depending on their type of species (brown, red, green and seagrass) and the ambient water conditions. However, the concentrations of Cr, Co, ni, se, Zr, Mo, Ag, Cs, La, sm, Eu, Yb, Hf, Ta, Au and U were very similar in all samples. In general the levels of classically investigated elements, particularly Mn, Fe, Co, ni and Zn determined in the macrophytes in the present study are lower or within the wide range of values previously reported for species of these genera sampled along the Egyptian Mediterranean coast.

大陆岩石圈地幔的定年是近年来大陆动力学研究中关注的焦点之一。很多探索表明:运用sm-nd,Rb-sr,U-th-Pb体系很难获取大陆岩石圈地幔的年龄,而Re-Os同位素体系的运用是解决这一问题的有效方法。玄武岩中的地幔岩捕虏体直接来自于岩石圈地幔,对它们的岩石地球化学,特别是Re-Os同位素研究在近年来取得了重大突破,极大地深化了对上地幔性质、动力学过程及其对浅部地质作用过程制约的认识。地幔岩捕虏体Re-Os同位素研究方法包括全岩Re-Os等时线法、全岩Os/Os值与主量元素AlO相关性的铝等时线法(Alumichron)和地幔岩捕虏体中硫化物的原位(in situ)激光探针-电感藕合等离子质谱法(LAM-ICPMs)。
