CLINICAL INTRODUCTION A 35-year-old male presented with painful skin rash for 2 hours after a clear liquid splashed onto his legs when a car drove past him and squelched a roadside container on a street populated by small-sized factories. Burning sensation and pain developed in 10 min. He called on the emergency room after irrigation. His trousers were intact, wet but not slippery, and had a pu...

Previous studies have shown that indigenous beetle diversity reflects indigenous plant diversity in modified and remnant habitats. This study examines the indigenous: introduced relationship at a locality where degraded pasture has been progressively revegetated. Pitfall traps were used to collect beetles from three revegetated sites of different ages (5, 17 and 100 years) and in a coastal Mueh...

By means of a Q-banding technique, virtually every chromosome in two heteroploid mouse cell lines, RAG and MSWBS, has been identified. The origin of 60 to 80% of the chromosomes has been established; the remaining chromo somes can be identified as markers characteristic of the cell line. The extent of chromosome heterogeneity has been ex amined and compared in these two mouse tumor cell lines. ...

WHAT THIS ARTICLE IS ABOUT The subtribe Flaveriinae (Asteraceae: Helenieae) includes a number of plant species sometimes called yellowtops, glowworts, and false broomweed. Different species of this subtribe differ in their chemical pathways involved in photosynthesis. Somes species use a system known as C 3 photosynthesis, some use a system known as C 4 photosynthesis, and others display charac...

Initiation of abscission at the pedicel-fruit zone in the sour cherry (Prunus cerasus L. cv. Montmorency) occurs near the transition of Stage II to Stage III of fruit growth. The preinitiation phase is characterized by a high fruit removal force (FRF) and explants prepared from fruits during this period do not undergo abscission as indexed by a reduction in FRF. Ethylene does not cause a signif...
