This initial survey of pollen from 192 samples from Hole 794A, supplemented by 189 samples from Hole 795 and 797B, suggests that marine pollen assemblages from the southwestern Sea of Japan provide a consistent Neogene pollen stratigraphy and a solid basis for regional paleoenvironmental reconstructions. Late Miocene vegetation inferred from these pollen data, a mix of conifer and broad-leaf el...

S ingle-molecule fluorescence (SMF) detection was first demonstrated in 1989 by Moerner and Kador. The capability to measure the physical properties of individual molecules one at a time circumvented the need to average the properties of an ensemble, and effects such as spectral diffusion could therefore be observed. One important consequence of SMF detection was soon recognized to be the capab...

Otrosina, W. J., Chase. T. E.. and Cobb, F. W., Jr. 1992. Allozyme differentiation of intersterility groups of Hererobasidion isolated from conifers in the western United States. Phytopathology 82:540-545. Allozyme analysis was conducted on 64 isolates from basidiocarps of Heterobusidion unnosum. The isolates belonged lo the “S” and “P” intersterility groups and were collected from live conifer...

Medicinal chemistry deals with study of structure and synthesis of drugs and there action of the body that is lots of works is done in clubbing of the molecules to get new pharmacological active drugs. In today’s world of medicine we was tried to produced a novel and potent drug which was having verity of activities and stable motiy our emphasis to prepared simple and potent moties in world of ...

Two new species of Centrolenella are described from the Pacific versant of the Andes in northern Peru (Rio Zana, Cajamarca Department). These constitute the first records for the genus on the western slopes of the Andes in Peru. Centrolenella euhystrix, a large species (males to 31.3 mm, females to 33.6 mm snout-vent length), has a distinctive coloration (dark greenish black when active at nigh...

The goal of N A S A ' s ,Vumerical A4erodynamic Simulation (.VAS) Program is to provide a powerful computational environment for advanced research and development in aeronautics and related disciplines. The present .VAS system consists of a Cray 2 supercomputer connected b y a data network t o a large mass siorage system, t o sophisticated local graphics workstations and b y remote communicatio...

The blocking actions of Fe 2÷, Co 2÷, and Ni 2÷ on unitary currents carried by Ba 2÷ through single dihydropyridine-sensitive Ca 2÷ channels were recorded from cell-attached patches on myotubes from the mouse C2 cell line. Adding millimolar concentrations of blocker to patch electrodes containing 110 mM BaCI z produced discrete excursions to the closed channel level. The kinetics of blocking an...

Digital Rights Management (DRM) is an important technology supporting e-commerce systems and online marketing, enabling content owners and market intermediaries to securely manage and deliver digital content. In addition, P2P (peer-to-peer) networks play a pro-motive role in e-commerce. However, it facilitates illegal access to copyrighted media which may cause a violation of content owners’ ri...

Bisphosphonates reduce bone turnover by inhibiting osteoclast maturation and function, and are important in the prevention of age-related osteoporosis and bone fracture, in the prevention of complications of bone metastases, and in the prevention of osteopenia and osteoporosis resulting from adjuvant aromatase inhibitor therapy of breast cancer. Over 125 years ago, in The Lancet, Paget hypothes...

Sir, L is a commonly used ant iconvulsant drug. Though i t i s cons idered as a benign drug; asthenia, headache, somnolence and nervousness are documented common side effect. Agranulocytosis is reported as a rare side effect with an incidence of approximately 1.2%, but almost always it is of moderate severity.1 Here we present a case of severe degree of agranulocytosis due to Levetiracetam. A 2...
