The capacity to precipitate quantitatively with homologous antiserum of native protoplasmic polysaccharide from Escherichia coli was not reduced by incubation in human plasma; it was reduced with the immunochemically related lipopolysaccharide.

Background: Formalin is an aqueous solution of formaldehyde. It is a protoplasmic poison and causes coagulation necrosis and tissue fixation. Case: A 19-year-old girl was brought for autopsy to the mortuary of JSS Medical College, Mysore. Conclusion: Formalin is an unusual poison to be ingested for suicidal purposes due to selective availability and its strong taste and odor.

Study of protoplasts, lysed protoplasts, and cells treated with lysozyme in the absence of osmotic stabilizer suggested that the alkaline phosphatase (EC 3.1.3.1.) of Bacillus subtilis is located in the protoplasmic membrane. Cytochemical evidence in support of this view is presented. The enzyme protein was strongly bound to the membrane structure and could not be solubilized by a number of tre...

The plasmodium of Physarum polycephalum is renowned for spanning sources of nutrients with networks of protoplasmic tubes. The networks transport nutrients and metabolites across the plasmodium’s body. To imitate a hypothetical colonisation of the world and formation of major transportation routes we cut continents from agar plates arranged in Petri dishes or on the surface of a three-dimension...

The precise localization of dystrophin in the skeletal muscle cell should contribute to a better understanding of the yet unclear functional role of this protein, both in normal and in Duchenne muscular dystrophy. Immunocytochemical studies did not give conclusive results on the localization of dystrophin with respect to the sarcolemma and to the cytoskeletal components. To improve the reliabil...

Protoplasmic astrocytomas are uncommon in humans and animals. A 14-year-old, intact female German Shepherd dog presented with a history of ataxia of the pelvic limbs, left-side head torsion and hypermetric response of the right side for approximately 15 days. Neurological examination revealed the presence of cerebellar syndrome and paradoxical vestibular syndrome. Medical therapy was initiated,...
