Microsporidia is increasingly being reported in the recent years in HIV-positive patients with diarrhoea.[1,2] Electron microscopy, though a gold standard for detection of microsporidial spores,[2] can only be used in sophisticated laboratories. Intestinal biopsy, though better, is not advocated in HIV-infected patients with diarrhoea because of its invasive nature.[3] therefore, trichrome stai...

Introduction: Measurements at high magnetic fields combined with improvements in localization techniques and with excellent shimming have led to important gains in sensitivity and spectral resolution of C in vivo spectra. Consequently, the amount of information that can be obtained from in vivo C spectra has considerably increased (i.e. signals from different carbon positions combined with a fi...

fig trees are threatened by the attack of fig mosaic disease (fmd) on leaves and fruits caused by viruses of several genera. shoot-tip culture is a convenient method for viral sanitation. for this purpose, a reliable protocol for rapid in vitro propagation was developed with shoot-tips of three major tunisian local fig (ficus carica l.) varieties zidi (zdi), soltani (sni), bither abiadh (ba) an...
