The convergent total synthesis of gambierol (1) is described. The octacyclic ether framework of 1 was constructed via the intramolecular allylation of alpha-chloroacetoxy ether followed by ring-closing metathesis. A modified Stille coupling was successfully applied to the synthesis of the triene side chain.

In developing countries pulmonary tuberculosis is usually diagnosed by detecting acid-fast bacilli (AFB) in sputum using a Ziehl-Neelsen (Z-N) staining method. However, in the field the traditional method of staining is difficult to carry out. This study evaluates the efficiency of two cold staining methods, namely Gabbet’s and a modified two reagent cold staining method compared with the Z-N t...

Several methods have been evaluated for the separation of red cells of different ages on the basis of density differences. Simple sedimentation and flotation technics have been found to be unsatisfactory. Centrifugation, followed by a modified sampling procedure, has been demonstrated to provide excellent separation of erythrocyte populations of different ages. Standardization of centrifuge con...
