Sir, Once more correspondence columns have borne witness to the confusion caused by the Leeds exercise test. Yet again Professor Linden and his colleagues have been able to claim that their protocol has not been adhered to-and of course on this occasion they are correct in that respect.'2 They have, however, chosen to ignore other studies that have followed their protocol meticulously and that ...

DNA preparations obtained from several tissues of Rhynchosciara americana and two related species, R. milleri and R. papaveroi, were hybridized to R. americana rRNA. The percentage of hybridization was found to be higher in tissues with low polyteny than in tissues with high polyteny, suggesting a relationship between the amount of rDNA and the tissue polyteny. This could be explained by under-...

Inhalation of allergens produced by the American cockroach (Periplaneta americana) induces IgE Ab production and the development of asthma in genetically predisposed individuals. The cloning and expression in Escherichia coli of P. americana tropomyosin allergen have been achieved. The protein shares high homology with other arthropod tropomyosins (80% identity) but less homology with vertebrat...

Abstraet--Sclerotized oothecae from four species of cockroaches, Periplaneta americana, P. fuliginosa, Blatta orientalis and Blattella germanica, were examined by solid-state 13C-nuclear magnetic resonance and chemical analyses. The oothecae were composed of protein, water, calcium oxalate, diphenolic compounds, lipid, and uric acid. Calcium oxalate was the major soluble component in egg cases ...

UNLABELLED PREMISE OF THE STUDY Microsatellite primers were developed for the tree species Genipa americana (Rubiaceae) for further population genetic studies. • METHODS AND RESULTS We identified 144 clones containing 65 repeat motifs from a genomic library enriched for (CT)8 and (GT)8 motifs. Primer pairs were developed for 32 microsatellite loci and validated in 40 individuals of two nat...

Ecologists often invoke interspecific facilitation to help explain positive biodiversity–ecosystem function relationships in plant communities, but seldom test how it occurs. One mechanism through which one species may facilitate another is by ameliorating abiotic stress. Physiological experiments show that a chronic excess of light can cause stress depresses carbon assimilation. If shading pla...

Macrofungal investigations were performed in gardens and avenues planted with Tilia spp. between 2009 2020 Hungary, focusing on the Budapest area. Lime tree (Tilia) is recently one of most favorable commonly used ectomycorrhizal urban landscaping Budapest, similarly to other European cities. As a result 71 sampling occasions total 60 epigeous hypogeous macrofungal species belonging 22 families ...

We present a much simplified version of the Collins-Gisin-Linden-Massar-Popescu inequality for the 2x2xd Bell scenario. Numerical maximization of the violation of this inequality over all states and measurements suggests that the optimal state is far from maximally entangled, while the best measurements are the same as conjectured best measurements for the maximally entangled state. For very la...
