A cross-sectional quantitative study of cutaneous bacterial and yeast flora at seven body sites in 99 human immunodeficiency virus-seropositive and 50 seronegative military personnel was performed. Statistically significant differences in carriage rates were only observed for Staphylococcus aureus on the foreheads of seropositive individuals. Seronegative individuals demonstrated staphylococcal...

The authors report on a study of detecting ricin molecules immobilized on chemically modified Au 111 surface by chemomechanically mapping the molecular interactions with a chemically modified atomic force microscopy AFM tip. AFM images resolved the different fold-up conformations of single ricin molecule as well as their intramolecule structure of Aand B-chains. AFM force spectroscopy study of ...

A series of 20 ,30-dideoxy-20,20-difluoro-40-azanucleosides of both pyrimidine and purine nucleobases were synthesized in an efficient manner starting from commercially available L-pyroglutamic acid via glycosylation of difluorinated pyrrolidine derivative 15. Several 40-azanucleosides were prepared as a separable mixture of aand b-anomers. The 6-chloropurine analogue was obtained as a mixture ...

Integrins are a large family of cell– extracellular matrix (ECM) and cell–cell adhesion molecules that regulate development and tissue homeostasis by controlling cell migration, survival, proliferation and differentiation (Hynes, 2002). They are non-covalently associated heterodimers consisting of aand bsubunits. On the cell surface, integrins exist in a conformation with either high (active) o...

We present ab-initio calculations of a variety of different lattice-gas interaction energies between Cu adatoms on Cu(001) and Cu(111). We find the next-nearest-neighbor (NNN) interactions to be negligible on Cu(111), explaining the success of the nearest-neighbor (NN) Ising model when describing the Cu(111) step stiffness. On Cu(001), however, we find that NNN interactions are roughly (1/7) th...

Idag finns det säkra och effektiva behandlingar mot många sjukdomar. Läkemedel är den vanligaste behandlingsformen i sjukvården och under 2006 hämtade sex miljoner svenskar (68%) ut ett eller fler recept på ett apotek i Sverige. Även om läkemedelsbehandling har många positiva effekter kan även oönskade och skadliga effekter vid läkemedelsbehandling uppkomma, dvs. läkemedelsbiverkningar. Innan e...

Sera from (259) sheep and (88) goats from Erbil city were examined for antibodies to Toxoplasma gondii by using latex, MAT, and ELISA. By using latex test, 75 (25.4%) sheep and 25 (28.4%) goats were seropositive. By testing the latex seropositive sheep serum by both MAT and ELISA the distribution of both positive and negative results were as such respectively: 63 (84%), 12 (16%), 11 (14.7%), 64...

conclusions we concluded that psychiatric patients in general and schizophrenia and bipolar cases in particular had a significantly higher relative frequency of t. gondii infection than healthy individuals of lorestan province, western iran. results out of the 170 psychiatric patients, 103 (63.5%) patients were seropositive for igg antibody and 14 (8.2%) were seropositive for igm antibody. of t...
