Yeast & Gold, Killed Cancerous Cells effectively

Date: 15 Sept. 2016

University: Cairo University – National Institute of laser enhanced sciences (NILES)

Techniques: Cytotoxicity, Nanotechnology

Summary: Unique Nanoparticles succeeded in killing Cancerous Cells in vitro

Study Story

By using nanotechnology applications, natural products, and useful living microorganisms; Cairo university researchers introduce a new way to reduce and treat cancer disease by the combination between two successful treatment pathways.

The story of this study began when the research team work at NILES found that all cancer treatments especially chemical treatments leave some toxins in the body which have serious side effects, and nanoparticles (which chemically synthesized) produce a good effect in killing cancerous cells, but it also may result in harmful side effects.

For the previous reasons; the development of environmentally benign nanoparticles and nanocomposites has growing interest, and in another hand, there are some previous studies found that the heat killed yeast especially Baker’s yeast succeeded in killing cancer cells when cultured with them in vitro.

So, what about the green bio-synthesis of nanoparticles using heat-killed Baker’s yeast?

The teamwork of the current study succeeded in the biosynthesis of gold nanoparticles in a moderate size by using Baker’s Yeast extraction under the effect of normal (visible) light, and evaluate the effect of this biosynthesized nanoparticles on killing cancerous cells in vitro using a type of cancer cells called Ehrlich ascites carcinoma cells.

The study was performed in 3 groups:

group no. 1: evaluating the effect of chemically synthesized gold nanoparticles on cancer cells killing

group no. 2: evaluating the effect of heat-killed baker’s yeast extraction on cancer cells killing.

group no. 3: evaluating the effect of (bio-synthesized gold/ yeast nanocomposites) on cancer cells killing.

what is the result?

The results of this study showed that the bio-synthesized gold/ yeast nanocomposites group have a higher effect on the destruction of cancerous cells more than group no.1 or group no. 2; therefore this combination gives new and more effective Cancer treatment pathway

Recommendations: the baker’s yeast which used in the preparation of food is a vital treatment when combined with gold nanoparticles to give us a new and unique treatment for cancer disease, and Recent Research studies site recommends in vivo study

Promising new drug for high blood pressure – zilebesiran

Promising new drug for high blood pressure According to one trial, a new medicine could help lower chronic high blood pressure for up to six months after a single injection. It’s called zilebesiran If effective, zilebesiran might give a more convenient approach of managing hypertension , which is currently treated with daily medications. More than half of people diagnosed with hypertension, do not take all of their prescription medication regularly, resulting in inconsistency in blood pressure control. Experts believe that better care of the patients whom suffering from high blood pressure could lower the risk of stroke, heart attack, and premature mortality. New drug for high blood pressure – zilebesiran The early stage clinical trials were carried out across four UK sites by an international team that included scientists from the University of Edinburgh’s Center for Cardiovascular Science. Patients who took zilebesiran ...

diabetes type 1 treatment without insulin – new study

diabetes type 1 treatment without insulin – new study a natural insulin substitute for type 1 diabetes , can type 1 diabetes be reversed if caught early , getting off insulin diabetes type 1 , how long can a type 1 diabetic go without insulin , how to cure type 1 diabetes permanently , reversing type 1 diabetes with diet , type 1 diabetes no longer needs insulin First Transplant Patient in BioHub Trial No Longer Needs Insulin Therapy In a clinical trial performed at Miami University (Diabetes Research Institute of its BioHub) a team of researchers succeeded in treating a woman diagnosed with diabetes mellitus type 1 completely; therefore she won’t need to insulin therapy again after undergoing an islets transplant surgery, but before illustrating this trial; we will know at first what are the reasons, symptoms, and complications of diabetes mellitus type 1. Diabetes mellitus type 1 causes In general, diabetic people suf...

قصص حقيقية لعلاج السرطان باستخدام الكركم

يُعد مرض السرطان واحدًا من الأمراض التي تتطلب تدخل علاجي دقيق من أجل التغلب على المرض وعلاجه بشكل نهائي، ولكن نظرًا إلى الآثار الجانبية الضارة التي تتركها العلاجات التقليدية لمرض السرطان ولاسيما العلاج الكيميائي أو الإشعاعي أو المناعي؛ فإن العلماء يتطلعون دائمًا إلى ابتكار وسائل علاجية أخرى تُساعد على علاج المرض بسهولة. قصص حقيقية لعلاج السرطان باستخدام الكركم تم إجراء عدد كبير من الدراسات البحثية الحديثة التي قد أكدت على دور مادة الكركمين المستخرجة من الكركم في علاج عدة أنواع من مرض السرطان، وقد جاءت بعض القصص الحقيقية أيضًا التي أكدت على ذلك على النحو التالي: قصة علاج سرطان الثدي يذكر أحد الأشخاص الذي يُدعى Bhadresh أنه كان لديه إحدى الصديقات اللاتي تعاني من مرض سرطان الثدي، وعندما قابلها بعد عدة سنوات؛ اكتشف أنها قد شُفيت تمامًا من المرض، وعندما سألها عن الخطة العلاجية التي اتبعتها؛ ذكرت له بأنها قد انتظمت في تناول الكركم يوميًا بمقدار 4 جرام تقريبًا، وهذا ما ساعدها على التخلص من المرض تدريجيا إلى أن شُفيت تمامًا. قصة علاج Dieneke Ferguson كما يوجد قصة أخرى خاصة بإمرأة ت...
