Renal proximal tubules are highly sensitive to ischemic and toxic insults and are affected in diverse genetic disorders, of which nephropathic cystinosis is the most common. The disease is caused by mutations in the CTNS gene, encoding the lysosomal cystine transporter cystinosin, and is characterized by accumulation of cystine in the lysosomes throughout the body. In the majority of the patien...

Cystinosis, the most frequent cause of inborn Fanconi syndrome, is characterized by the lysosomal cystine accumulation, caused by mutations in the CTNS gene. To elucidate the pathogenesis of cystinosis, we cultured proximal tubular cells from urine of cystinotic patients (n = 9) and healthy controls (n = 9), followed by immortalization with human papilloma virus (HPV E6/E7). Obtained cell lines...

Cystinosis is a rare disorder, and, accordingly, progress on the understanding and treatment of this disease has been relatively slow. Although cystinosis was identified over 100 years ago, the history of cystinosis is marked by a few sudden leaps forward in our understanding rather than by a sustained research effort fuelled by the larger research community. Major conceptual break-throughs inc...

هدف: از چالش­های عمده بشریت افزایش افسردگی و اختلال عملکرد جنسی ناشی داروهای ضدافسردگی است. با توجه به نقش سلول­های سرتولی در اسپرماتوژنز، پژوهش حاضر، اثر داروی دولوکستین را بر زنده­مانی، آپوپتوزیس بیان ژن­های Bax و­ (Connexin 43) Cx43 بررسی کرده مواد روش‌‌ها: TM4 محیط DMEM/F12 حاوی %5/2 FBS، 5% سرم اسب %1 پنی سیلین-استرپتومایسین کشت شدند. دوزهای 30،60، 15، 5/7، 75/3 میکرو­گرم/ میلی­لیتر زمان­ه...

Billions of people in the world live under heavy information censorship. We propose a new class of delay tolerant network (DTN), known as a censorship tolerant network (CTN), to counter the growing practice of Internet-based censorship. CTNs should provide strict guarantees on the privacy of both information shared within the network and the identities of network participants. CTN software need...
