pulmonary langerhans cell histiocytosis (plch) is a rare idiopathic disorder that primarily affects young adult cigarette smokers. affected patients often present with cough and dyspnea and about 20% of patients present with or later develop pneumothorax. it is striking that more than 90% of patients are smokers. we report a very unusual case of plch in a 20-year- old male patient with no smoki...

Self-programmed enzyme phase separation is exploited to assemble dynamic multiphase coacervate droplets via spontaneous polyion self-sorting under non-equilibrium conditions.

Tumor lysis syndrome (TLS) complicating non-hematologic malignancy is infrequent and spontaneous TLS is a very rare occurrence in patients with solid tumors. We report a case of spontaneous TLS in a patient with metastatic melanoma. Clinicians should have awareness of the possibility of spontaneous TLS in patients with solid tumors and should recognize the clinical presentation and laboratory t...

objective(s)distinction of hydatidiform moles from non-molar specimens and subclassification of hydatidiform moles as complete and partial are important for clinical practice, but diagnosis based solely on histomorphology suffers from poor interobserver reproducibility. nowadays, pathologists rely on molecular techniques, however these methods are technically difficult, relatively expensive, an...

background: spontaneous ovarian hyperstimulation syndrome rarely occurs during pregnancy and is usually associated with high levels of human chorionic gonadotropin, in conditions such as molar or multifetal pregnancies. case report: here we report spontaneous ovarian hyperstimulation in a patient presenting with missed abortion at 16th week of gestation, when serum ß-subunit human chorionic gon...

background: spinal cord injury (sci) is a major clinical condition and research is commonly done to find suitable treatment options. however, there are some degrees of spontaneous recovery after sci and gender is said to be a contributing factor in recovery, but this is controversial. this study was done to compare the effects of sexual dimorphism on spontaneous recovery after spinal cord injur...

one of the most controversial and unresolved questions in bilingual first language acquisition (henceforth bfla) is whether bilingual children develop one mixed or two independent linguistic systems. many scholars in the lield of bfla arc in tavor of the one-system hypothesis (leopold 1970; swain and wesche, 1975; volterra and tacschner, j 987; grosjean, 1982; tacschncr, 1983: mclaughlin, 1984:...
