we describe a 16 year old boy with acne fulminans associated with axial and peripheral polyarthritis. the patient's clinical course and therapy with isotretinoin, prednisolone and oxytetracycline are described. a possible association between the presence of hla -b 27 antigen and reactive arthritis with acne fulminans in this case is evaluated. a review of the literature is included.

sperm is particularly susceptible to reactive oxygen species (ros) during critical phases of spermiogenesis. however, the level of seminal ros is restricted by seminal antioxidants which have beneficial effects on sperm parameters and developmental potentials. mitochondria and sperm plasma membrane are two major sites of ros generation in sperm cells. besides, leukocytes including polymer phonu...

argyrophilic nucleolar organizer regions (agnors) were determined in 94 pleural, pericardial and peritoneal effusions. the results were correlated with cytologic diagnosis to determine the diagnostic potential of this technique. cytologically the number of normal, reactive and malignant effusions were 32, 28 and 34 respectively. the mean agnor counts for normal, reactive and malignant specimens...

The current commercial application of ink-jet reactive inks to cotton fabrics has been through pre-treating with pad liquor prior to printing. In This study made an effort to provide a single phase ink-jet printing process for printing cotton fabric using the novel cationic reactive dye in ink’s formulation. Cotton fabric was printed upon with the novel cationic reactive dye and commercial anio...

In this paper, a new structure for reactive power market is presented. Considering reactive power losses caused by active power flow in the reactive power market is the main purpose of this paper. Hence, this study tries to improve reactive power market and create fair competition in reactive power generation.

reactive oxygen species (ros) are produced in many normal and abnormal processes in humans, including atheroma, asthma, joint diseases, cancer, and aging. basal levels of ros production  in  cells  could  be  related  to  several  physiological functions  including  cell proliferation, apoptosis and homeostasis. however, excessive ros production above basal levels would impair and oxidize dna, ...

abstract   background : cancer has not been elucidated in colerectal site. c-reactive protein (crp) is a product synthesized in hepatocytes and has been reported to be up-regulated by such proinflammatory cytokines as interleukin-1 (il-1), interleukin-6 (il-6), and tumor necrosis factor (tnf). the significance of a preoperative serum elevation was evaluated using crp as a predictive indicator f...

Argyrophilic nucleolar organizer regions (AgNORs) were determined in 94 pleural, pericardial and peritoneal effusions. The results were correlated with cytologic diagnosis to determine the diagnostic potential of this technique. Cytologically the number of normal, reactive and malignant effusions were 32, 28 and 34 respectively. The mean AgNOR counts for normal, reactive and malignant spec...
