kikuchi-fujimoto disease (kfd) is a benign, self-limiting disease characterized by histiocytic necrotising lymphadenitis. though several viral agents or an autoimmune etiology has been proposed as causative, the exact cause remains unknown. it has a female predilection and most commonly seen among young asian people. patients usually present with a febrile illness and the presence of lymphadeno...

common bean (phaseolus vulgaris l.) is one of the most important food legumes worldwide. the development of a core collection could facilitate easier access to bean genetic resources and enhance their applications in crop improvement program. in this article development of a core collection from 1425 accessions of common bean germplasm available from the national plant gene bank of iran (npggbi...

  Cryptosporidium species are one of the most common causes of gastrointestinal infection in humans around the world. This study has aimed to investigate the hyper variable region of the 18S rRNA gene in Cryptosporidium for exact parasite identification .   DNA was extracted from 26 fecal samples from which initially Cryptosporidium oocysts were identified by Ziehl-Neelsen acid-fast , Auramine ...

introduction systemic lupus erythematous (sle) is among rheumatic diseases of unknown etiology. fever of unknown origin (fuo) has been rarely reported to be the presenting sign of sle. presence of four or more sle criteria is diagnostic for the disease. however, presentations may occur serially which make it much more difficult to diagnose an already questioned fuo. case presentation our case o...

background: although infectious diseases are the most common sources for the fever of unknown origin (fuo), but the spectrum of infectious diseases is changing overtime. the purpose of the study was to define the clinical spectrum and changing the pattern of fuo.methods: this existing data based study was undertaken from 2007 to 2011. one hundred-six patients fulfilling the modified criteria fo...

photocatalytic reduction of carbon dioxide to formaldehyde was investigated on four semiconductor photocatalysts (fes, fes/fes2, nio and tio2). the reaction was carried out in continues flow of co2 gas bubbled into the reactor. semiconductor photocatalysts were characterized by x-ray diffraction (xrd) and diffuse reflectance spectroscopic (drs) methods. sulfide ion was used as hole scavenger. t...

conclusions: absence of the c allele was significantly associated with failure of response. the presence of c allele was associated with a favorable outcome. afp is a strong baseline predictor of hcv treatment response. a decision tree model is useful for predicting the probability of response to therapy. patients and methods: the study included 263 chronic hcv egyptian patients receiving peg-i...

Natural time chi enables the distinction of two origins of self-similarity, i.e., the process memory and the process increments infinite variance. Employing multiplicative cascades in natural time, the most probable value of the variance kappa(1)(is identical to chi(2)-chi(2))is explicitly related with the parameter b of the Gutenberg-Richter law of randomly shuffled earthquake data. Moreover, ...
