In shallow rainfed rice agro-ecosystems, drought stress can occur at any growth stage and can cause a significant yield reduction. During recent years, some rice varieties possessing tolerance of reproductive-stage drought stress have recently been developed. Tolerance of vegetative-stage drought stress is also required to improve rice productivity in drought-prone regions. In this study, we ev...

Bacillus sphaericus was used to control Culex pipiens breeding in a water treatment settling basin near Montpellier, France. Four treatments with 4 liters/ha (3.6 lb/acre) of commercially available B. sphaericus formulation (Vectolex) reduced the larval population of Cx. pipiens with 50-600 spores of B. sphaericus/ml recorded in the treated portions of the water plant 14 days following the last...

among troops evacuated from Burma, most of whom had come through the so-called ' DryBelt ', some had severe hemorrhage per rectum. These cases had vegetative forms of Entamoeba histolytica in large numbers in the stools and these could be found even in the almost pure blood passed. The usual routine treatment of emetine, bowel washes, salines, etc., had no effect on the haemorrhage nor had the ...

Amongst the various forms of headache migraine is differentiated by three main criteria: (1) intense pain, hemicranic in type, of which (2) beginning and termination are clearly defined (meaning pain occurs in socalled fits or attacks) and which is (3) recurring periodically. It should be distinguished from continuous headache (vasomotor cephalea) even if the latter is only one-sided (hemicrani...

The morphological, cu1ωral, physiologicai and blochemical characteristics of a new actinomycete strain producing a new antibiotic, setamycin are described. The strain forms aerial mycelia. There is no fragmentation of vegetative mycelia. Since the cell wall type is a new one containhlg both LL-and meso-2,6-diaminopimelic acid, glyclne and galactose, strain KM6054could not be classified in any p...

Volvariella volvacea, strain V14, produces multiple forms of extracellular laccase when grown in submerged culture in a defined medium with glucose as sole carbon source, and on cotton waste 'compost' representative of the conditions used for industrial-scale mushroom cultivation. In liquid culture, enzyme synthesis is associated with the onset of secondary growth, and is positively regulated b...

Regulated aggregations of prion and prion-like proteins play physiological roles in various biological processes. However, their structural roles in the nucleus are poorly understood. Here, we show that the prion-like protein Jub6p is involved in the regulation of chromatin structure in the ciliated protozoan Tetrahymena thermophila Jub6p forms sodium dodecyl sulfate (SDS)-resistant aggregates ...

Pyoderma gangrenosum is a rare idiopathic skin disease. It affects mainly adults, and only 4% of the cases are diagnosed on children and adolescents. There are four clinical forms of pyoderma gangrenosum: ulcerative, pustular, bullous, and vegetative (superficial granulomatous pyoderma). Superficial granulomatous pyoderma is considered the most benign and uncommon form of the disease. Patients ...
