Context. The observed abundance peculiarities of many chemical species relative to the expected cluster metallicity in blue horizontal-branch (BHB) stars presumably appear as a result of atomic diffusion in the photosphere. The slow rotation (typically v sin i < 10 km s) of BHB stars with effective temperatures Teff > 11,500 K supports this idea since the diffusion mechanism is only effective i...

An endophytic fungus isolated from the plant Cinnamomum mollissimum was investigated for the bioactivity of its metabolites. The fungus, similar to a Phoma sp., was cultured in potato dextrose broth for two weeks, followed by extraction with ethyl acetate. The crude extract obtained was fractionated by high-performance liquid chromatography. Both crude extract and fractions were assayed for cyt...

Endophytic fungi are specific microbes that live at a specific ecosystem in nature. Various endophytic fungi have been known posses an ability to produce a broad range of biologically active substances. Totally 53 endophytic filamentous fungi were isolated from leaves, stems, fruits and roots of the two plant varieties of Uncaria gambier Roxb. (Rubiaceae), i.e. gambir udang and gambir nasi. Mor...

During the course of our screening for squalene synthase inhibitors and Ras farnesylation inhibitors, a novel fungal culture was discovered to produce two structurally unique compounds, CP-225,917 and CP-263,114, as well as zaragozic acid A (squalestatin I). The two compounds are characterized by a bicyclo[4.3.1]dec-1,6-diene core plus two extended alkyl chains. CP-225,917 and CP-263,114 inhibi...

This study reports the first assessment of endophytic fungi isolated from strawberry leaves and selection of isolates for the control of Duponchelia fovealis, a new pest of strawberries. A total of 400 strawberry leaves of the cultivar 'Albion' were collected in four commercial farms. Leaves were disinfected, cut in fragments, and placed on Petri dishes containing potato dextrose agar media wit...

Successful treatment of melanoma and lymphoma may result from the induction of specific antitumor immunity. Dendritic cells (DCs) are pow erful antigen-presenting cells and show a remarkable capacity to stimulate antigen-specific T-cell responses. Administration of FLT3 ligand (FL) results in a reversible accumulation of functionally active DCs in both lymphoid and nonlymphoid tissues. Therefor...

Spent coffee grounds (SCG), obtained during the processing of coffee powder with hot water to make soluble coffee, are the main coffee industry residues and retain approximately seventy percent of the polysaccharides present in the roasted coffee beans. The purpose of this study was to extract polysaccharides from SCG by using an alkali pretreatment with sodium hydroxide at 25°C, and determine ...

The Present investigation was conducted during the year 2012-2013, to study the phylloplane flora from some novel plants of family Ficaceae. It was observed that in nature the plants faces several problems in terms of attack of several pathogens, which cause the diseases. By keeping this view in mind, the above titled study was conducted to observe the relative phylloplanic flora on the sacred ...

Fresh collections, type studies and molecular phylogenetic analyses of a multigene matrix of partial nuSSU-ITS-LSU rDNA, rpb2, tef1 and tub2 sequences were used to evaluate the boundaries of Cucurbitaria in a strict sense and of several related genera of the Cucurbitariaceae. Two species are recognised in Cucurbitaria and 19 in Neocucurbitaria. The monotypic genera Astragalicola, Cucitella, Par...

With a newly developed turbidometric method, concana valin A was shown to agglutinate normal lymphocytes, lym phoma cells, and leukemic cells from chronic lymphocytic leukemia and from acute myelocytic and lymphocytic leuke mia. However, there was a marked difference in the kinetics of this agglutination process. Leukemic blast cells and cells from a patient with convoluted lymphoma agglutinate...
