সম্প্রতি, এমআইটির বিজ্ঞানীরা হিমাস্ট্যাটিন (Himastatin) নামক এক জটিল প্রকৃতিক অণু সংশ্লেষণের অভিনব পদ্ধতি আবিষ্কার করেছেন। যার ফলে, হিমাস্ট্যাটিনে থাকা অ্যান্টি-বায়োটিক সম্ভাবনাকে অ্যান্টি-বায়োটিক হিসেবে ব্যবহারের বিপুল সম্ভাবনা উঁকি দিচ্ছে।
ম্যাসাচুসেট্স ইন্সটিটিউট অব টেকনোলজি (এমআইটি)-র বিজ্ঞানীদের আবিষ্কৃত নতুন সংশ্লেষণ পদ্ধতি ব্যাবহার করে গবেষকরা হিমাস্ট্যটিন এবং এর নতুন নতুন ভ্যারিয়েন্ট উন্মোচন করতে পেরেছেন। এর অনেকগুলো ভ্যারিয়েন্টই জীবাণু প্রতিরোধী অ্যান্টিবায়োটিক হিসেবে কাজ করে বলে দেখা গেছে। এটি ব্যাকটেরিয়ার কোষঝিল্লি আক্রমণ করে ব্যাকটেরিয়ার কার্যক্ষমতা নষ্ট করে দেয়। এখন বিজ্ঞানীরা পূর্বাপেক্ষা শক্তিশালী অ্যান্টি-বায়োটিকের নঁকশা করার আশা করছেন।
এমআইটির একজন রসায়নের অধ্যাপক মোহাম্মদ মুফসেগ বলেছেন, ”আমরা এখন যা করতে চাই তা হলো, এটির সম্পর্কে বিস্তারিত জানা। এটির কাজের কৌশল সম্পর্কে জানা। যার ফলে আমরা এর কর্ম-কৌশল কে ত্বরান্বিত করতে পারব। এখন আমরা এর ভৌত ও রাসায়নিক বিষয়গুলি সম্পর্কে জানার চেষ্টা করছি। অনুসন্ধান করছি যে কীভাবে এটি ব্যাকটেরিয়ার কোষ-ঝিল্লিকে আক্রমণ করে। ”
হিমাস্ট্যাটিন মাটিতে বসবাসকারী একপ্রকার ব্যাকটেরিয়া দ্বারা প্রাকৃতিকভাবে উৎপাদিত হয়। এটি প্রথম আবিষ্কৃত হয় ১৯৯০ সালে। প্রাণী গবেষণায়, এটির ক্যান্সার প্রতিরোধী কার্যকলাপ লক্ষ্য করা গিয়েছিলো। কিন্তু এর জন্য প্রয়োজনীয় ডোজ তীব্র পার্শ্বপ্রতিক্রিয়াযুক্ত। তখন যৌগটির সম্ভাব্য জীবাণুরোধী কার্যকলাপও লক্ষ্যণীয় ছিলো। কিন্তু সেই সম্ভাবনা নিয়ে বিস্তারিত ভাবে গবেষণা করা হয়নি।

হিমাস্ট্যাটিন একটি জটিল যৌগ যা দুটি অভিন্ন সাব-ইউনিট মনোমার দ্বারা গঠিত। দুটি মনোমার যুক্ত হয়ে ডাইমার গঠন করে। এই দুটি সাব-ইউনিট একটি ছয় কার্বন বিশিষ্ট রিং এর দ্বারা পরস্পর যুক্ত থাকে। এই কার্বন-কার্বন বন্ধনটি যৌগটির জীবাণুরোধী কার্যকলাপের জন্য গুরুত্বপূর্ণ। প্রথম দিকে গবেষকরা হেমাস্টাটিন সংশ্লেষণের জন্য এই বন্ধনটি তৈরি করার চেষ্টা করছিলেন। কিন্তু MIT এর গবেষকরা ভিন্ন পদ্ধতি অবলম্বন করেছেন। তারা ব্যাকটেরিয়া গুলো যেভাবে হেমাস্টাটিন উৎপন্ন করে সেই পদ্ধতি অবলম্বন করেছেন। ওই ব্যাকটেরিয়াগুলো বিশেষ এনজাইম ব্যবহার করে দুটি মনোমারকে কার্বন বন্ধনের সাথে যুক্ত করে।
গবেষকেরা প্রথমেই অ্যামাইনো এসিডের বিল্ডিং থেকে জটিল মনোমার তৈরি করেছিলেন। তারপর তারা এমআইটির মভসাঘি গ্রুপ দ্বারা উদ্ভাবিত নতুন একটি ডাইমেরিজেশন কৌশল ব্যবহার করেন। ফলে অ্যানিলিন জারিত হয়ে কার্বন র্যাডিকেল তৈরি হয়।পরে এরা বিক্রিয়া করে কার্বন বন্ধন তৈরি করে যেটি মনোমারের সাথে যুক্ত হয়। মভসাঘি গ্রুপ এই কৌশল নিয়ে খুবই আনন্দিত।
গবেষকেরা হিমাস্ট্যাটিনের জীবাণুরোধী ক্ষমতা বিশ্লেষণ করতে একটি বিশেষ শ্রেণী নিয়েও গবেষণা করেছেন। তারা বুঝেছেন যে, এটি ব্যাকটেরিয়ার কোষ-ঝিল্লিকে নষ্ট করে ফেলে। এখন তারা আরো অনেক শ্রেণী নিয়ে গবেষণা করার পরিকল্পনা করছেন।যার কারণে তারা আরো শক্তিশালী অ্যান্টি-বায়োটিক তৈরির আশা রাখছেন।

I recently found out that a chef I know has been planning to apply his culinary skills to make psilocybin chocolate for exactly this reason. Having been a chef myself for many years now, I was left to wonder: How many different ways can you incorporate psilocybin into a snack or a meal? Could I just add magic mushrooms to my favorite recipes? A: Here are 5 best ways to consume magic mushrooms: Get more info on mushrooms here and check out our blog for even more mushroom recipes. You need only look to the psychoactive effects of hallucinogenic mushrooms and the toxicity of poisonous varieties to understand that mushrooms can have potent biochemical effects says David Hibbett, PhD., a mycologist (mushroom expert) and professor of biology at Clark University in Worcester, Massachusetts. “Mushrooms produce a lot of interesting chemical compounds that could be defensive,” he says, and that might be useful for fending off bacteria and other bodily invaders that make us sick. “Fungi produce some of our most important drugs,” says Hibbett, pointing out that both penicillin and cholesterol-lowering statins were derived from fungi, the category of organisms that includes mushrooms.

In addition to the gameplay updates, KamaGames has introduced a new in-game newsfeed allowing them to communicate directly with their community and over 500,000 daily active players sharing news on sales, tournaments, when each new poker mode is launched and lots more. Best Mobile App Awards zeichnete Pokerist Texas Poker als eines der besten Spiele 2013 in der Kartenspiel- und Casino-Kategorie ihrem Platinum Award aus. Worst App Ever Veröffentlichungstermine = 29.05.2010 facebook.com Pokerist 1. Erfolg in diesem Spiel bedeutet nicht, dass Sie auch Erfolg in ähnlichen Casino-Spielen haben, bei denen echtes Geld gewonnen werden kann. Von den 2 Milliarden angemeldeten Messenger Nutzern sind rund 1,3 Milliarden Menschen regelmäßig aktiv. Neben dem zu erwartenden Kundenzufluss über Facebook bietet KamaGames seinen Pokerist außerdem über das russische soziale Netzwerk VK an. Dort sind weitere 90 Millionen Menschen registriert. Über andere Anbieter spielen derzeit rund 400.000 Menschen aktiv über den Pokerist. Mit diesen können nun auch die neuen Facebook Spieler in Verbindung treten und über die Software mit- und gegeneinander spielen. https://eduardocsgv764319.ampblogs.com/wunderino-automaten-48553219 Online hat der Spielautomat einen Auszahlungsprozentsatz von 92,13 Prozent. Das sind ein paar Prozentpunkte mehr als bei der physischen Version. Darüber hinaus hat Novomatic Book of Ra online so intakt wie möglich gehalten. Es gibt nicht viele Online-Casinos, in denen Sie Book of Ra spielen können. Novomatic zieht es vor, Book of Ra so exklusiv wie möglich online zu halten. Die Österreicher sind natürlich bestrebt, ein eigenes Online-Casino zu entwickeln. Mit vielen bekannten Novomatic-Slots. Selbstverständlich stellen wir auch die mobile Version von Book of Ra Deluxe unseren Spielern zur Verfügung. Egal ob Andriod oder iPhone. Abgesehen davon laufen die Spiele auch auf Tablets und anderen mobilen Endgeräten. Vielen Spielern ist die Relevanz der individuellen Auszahlungsquote offensichtlich gar nicht bewusst. Dabei ist die Quotenhöhe unstrittig verantwortlich für die langfristige Gewinnstatistik eines jeden einzelnen Spielers. Bei attraktiveren Quoten wird der Spieler statistisch gesehen auf langer Sicht mehr gewinnen, als wenn die Quote „nur“ im durchschnittlichen Bereich liegt. Book of Ra war stets als gewinnträchtiger Spielautomat bekannt. Insbesondere die Book of Ra Freispiele haben teilweise zu überragenden Gewinnserien geführt, von denen Spieler noch Monate später geschwärmt haben.

Hallucinogens like psilocybin can be eliminated from the body quickly. Still, the time between ingesting shrooms and testing could be a factor — if the right type of test is used, of course. John Hughes is a fungi expert at Shropshire Wildlife Trust, and says that fungi grow and fruit at different rates depending on the conditions. Mushrooms are a difficult thing to grow with any confidence anyway, but something in the air this winter is bringing them above ground. According to the rock paintings and sculptures of North African culture, the magic mushrooms were used long back in 9000 B.C. People started consuming them on a large scale by 1950. They contain psilocybin, which is a psychedelic compound, creating a hallucination and a feeling of euphoria. For this reason, they are listed in CSA (Schedule 1 drugs) in the United States. However, magic mushrooms have less potential for offense than other Schedule 1 drugs and are more potent in medicinal and cultural uses. https://letibri.com/index.php/community/profile/boriswaddy16709/ Since 1997, public opinion polls have found that an increasing majority of Canadians agree with the statement, “Smoking marijuana should not be a criminal offence”. A June 2016 national poll conducted by Nanos Research showed that 7 in 10 Canadians were in favour of legalization. For more information about this bulletin, contact Measurement Canada. Under the proposed Federal Cannabis Act, all producers of cannabis or cannabis products will need to be federally licensed to operate. The Government of Canada will establish application processes and criteria for people who want to become producers of legal recreational cannabis. The objectives of this study are to: The Canadian regulatory landscape governing the cannabis industry is complex and continuously evolving. Prior to getting involved in the legal cannabis industry in Canada, whether as an investor or entrepreneur, producer or retailer, or otherwise, it is important to understand the regulatory restrictions of the current regime. Please contact us if you have any questions or comments with respect to any of the above information.
