Intact monolayers of L6 myoblasts were treated with neuraminidase, with the aim of selectively removing sialic acid residues of cell-surface glycoproteins. Neuraminidase treatment unmasked binding sites for Ricinus communis agglutinin I and peanut agglutinin, thus allowing the identification of the major binding proteins for these lectins. For Ricinus communis agglutinin I these neuraminidase-s...

The order Hymenoptera currently includes the impressive number of more than 115000 known species. The tropical hymenopteran fauna, however, is poorly known and this number probably represents just a small fraction of the real richness of the group. A great part of the species within Hymenoptera is composed of parasitoids, animals that exploit other organisms to death in order to acquire the foo...

In a first of its kind, a 20 year old Hindu, highlander, working girl presented with abnormal behavior, unrelenting symptoms, had limited benefit by usual treatment and was diagnosed as possession syndrome. Exorcism offered symptomatic relief. The girl resumed normal activities with no recurrence in a 12 month follow up. Possession syndrome is explained in both medical and theological perspecti...

The modern human face differs from that of our early ancestors in that the facial profile is relatively retracted (orthognathic). This change in facial profile is associated with a characteristic spatial distribution of bone deposition and resorption: growth remodeling. For humans, surface resorption commonly dominates on anteriorly-facing areas of the subnasal region of the maxilla and mandibl...

Owing to its completeness, the 1.5 million year old Nariokotome boy skeleton KNM-WT 15000 is central for understanding the skeletal biology of Homo erectus. Nevertheless, since the reported asymmetries and distortions of Nariokotome boy's axial skeleton suggest adolescent idiopathic scoliosis, possibly associated with congenital skeletal dysplasia, it is questionable whether it still can be use...
