A 26-year-old white woman with no personal or family history of interest was referred to our department for a highly pruritic rash on the back of the neck, upper part of the back, and inframammary region (Figure 1, A and C). The rash had developed 3 months earlier and was resistant to treatment with topical and oral corticosteroids and oral antihistamines. The patient stated that she had had a ...

BACKGROUND AND AIM OF THE WORK Malaria is a protozoan infection caused by parasites of the genus Plasmodium (P. falciparum, P. ovale, P. vivax, P. malariae) that is transmitted from one human to another by female Anopheles mosquitoes. It can be considered a reemerging imported disease in our area because of increasing of movements from endemic countries, and nowadays it is the most common impor...

We report data demonstrating that zebrafish embryos irradiated by alpha particles can release a stress signal into the water, which can be communicated to the unirradiated zebrafish embryos sharing the same water medium and thereby inducing a radioadaptive response in these unirradiated zebrafish embryos. The effects of radiation on the whole embryos were studied through quantification of apopt...

In the mol-ecule of the title compound, C(21)H(19)NO, the terminal saturated six-membered ring of the dihydro-acridine unit adopts an envelope conformation, while the other two fused rings are nearly coplanar, with a dihedral angle of 2.61 (3)°. The coplanar ring system is oriented with respect to the phenyl ring at a dihedral angle of 74.58 (3)°. In the crystal structure, there is a C-H⋯π cont...

The photostability of dye molecules trapped in transparent solid matrices synthesized by the solgel technique was studied both experimentally and theoretically using a model with numerical and approximate analytical solutions. The model is based on a one-photon photodestruction process with the creation of an absorbing bleached molecule. We give the number of photons that different trapped dye ...

Vietnam veterans' risks for fathering babies with major structural birth defects were assessed using a case-control study. Information regarding military service in Vietnam was obtained from interviews with mothers and fathers of babies in case and control groups and from review of military records. Vietnam veterans, in general, did not have an increased risk of fathering babies with defects (a...

Bacteriol. 92:1469-1472. 1966.-A test for the release of extracellular ribonuclease by Bacillus subtilis colonles was developed. The method consists of incorporating acridine orange and ribonucleic acid int...

Acridine orange (AO) has been used to vitally stain somatic and germinal nuclei in vivo (1, 2) and to differentially fluorochrome living and dead bacteria, yeast, and onion root tip cells. The latter phenomenon was discovered by Strugger, whose book, Fluoreszenzmikroskopie und Mikrobiologie (7), details the technics required for adapting the metafluorochromatic staining as a test of cell viabil...
