پژوهشی جدید در دانشگاه ویک فارست نشان داده است که میتوان با استفاده از سلولهای بنیادی مغز استخوان بابون، بافت مثانه عملکردی را بازسازی کرد. 📚🪄🔬✨
این فرآیند شامل استفاده از داربست زیستتخریبپذیر است که با سلولهای بنیادی پوشش داده شده و در ناحیه مثانه آسیبدیده کاشته میشود. سلولها در محل تکثیر یافته و بافتی تولید کردند که ساختاری و عملکردی مشابه مثانه طبیعی دارد. این بافت طی دو سال عملکرد خود را حفظ کرد، نشاندهنده پتانسیل بالای این روش برای درمان آسیبها یا نواقص مثانه است.

One thing that Telegram now offers to all users is the ability to “disappear” messages or set remote deletion deadlines. That enables users to have much more control over how long people can access what you’re sending them. Given that Russian law enforcement officials are reportedly (via Insider) stopping people in the street and demanding to read their text messages, this could be vital to protect individuals from reprisals. The Security Service of Ukraine said in a tweet that it was able to effectively target Russian convoys near Kyiv because of messages sent to an official Telegram bot account called "STOP Russian War." On December 23rd, 2020, Pavel Durov posted to his channel that the company would need to start generating revenue. In early 2021, he added that any advertising on the platform would not use user data for targeting, and that it would be focused on “large one-to-many channels.” He pledged that ads would be “non-intrusive” and that most users would simply not notice any change. Right now the digital security needs of Russians and Ukrainians are very different, and they lead to very different caveats about how to mitigate the risks associated with using Telegram. For Ukrainians in Ukraine, whose physical safety is at risk because they are in a war zone, digital security is probably not their highest priority. They may value access to news and communication with their loved ones over making sure that all of their communications are encrypted in such a manner that they are indecipherable to Telegram, its employees, or governments with court orders. Pavel Durov, Telegram's CEO, is known as "the Russian Mark Zuckerberg," for co-founding VKontakte, which is Russian for "in touch," a Facebook imitator that became the country's most popular social networking site.
