OBJECTIVES We present a new technique of transurethral prostatic enucleation. METHODS. We use an Olympus resectoscope with two electrodes; one has a button or "mushroom" shape to vaporize and enucleate, and the other one the shape of a conventional "cutting loop electrode"to resect. With the button-shaped electrode, we vaporize transversally at the level of the veru montanum, extending the diss...

Hydride generation atomic absorption spectrometry (HGAAS) was applied for determination of selenium content in dried aerial parts of wild and cultivated Teucrium species (Lamiaceae) growing in Croatia: T. arduini L., T. chamaedrys L., T. flavum L., T. montanum L., T. polium L., and T. scordium L. subsp. scordioides Schreb. Special attention was paid to the wet oxidation procedure for the sample...

Cold-hardened dark-grown seedlings of winter wheat (Triticum aestivum L.) and winter rye (Secale cereale L.) are killed during total encasement in ice at -1 C at a rate related to the initial cold hardiness of the cultivars. Few plants remain alive after 7 days of encasement. Nonhardened seedlings are rapidly killed in ice. The respiratory properties of mitochondria isolated from plants after i...

Seventeen genera and 48 species, in five subtribes, are recognized in Thailand. These include 15 endemic taxa, half of which are in the largest genus, Acilepis, with others in the genera Camchaya, Koyamasia, and Okia. A new monotypic genus, Pulicarioidea, is established with P. annamica, the new name for the species formerly known as Vernonia pulicarioides. New combinations are also made for Ac...

Cytoplasmic male sterility (cms) in rye (Secale cereale L.), especially cytoplasma PAMPA, is used commercially in hybrid breeding programmes. The development of molecular markers that are tightly linked to the numerous genes coding for pollen fertility is expected to have great impact in the field. Morphological and cytological analyses of plants from a three-way cross C394: [(S67P/94 x S38/94)...

"Flour dust" refers to dust coming from fmely milled or othenvise processed cereal. Hypersensitivity reactions as well as irritant syrnptoms caused by flour dust constitute a well recognized occupational problem world-wide. Most data on flour dusts have been derived fiom studies on wheat (Triticum sp.) and rye (Secale cereale), and to a lesser extent on barley (Hordeum sp.) and oats (Avenea sat...
