Noninvasive Quality Control of Cryopreserved Samples

Noninvasive Quality Control of Cryopreserved Samples.

We present a novel noninvasive technology for quality control in biobanking. We implemented a contactless optical in situ method with a remote detection unit. The method detects physical and chemical changes by emission spectroscopy. In the present study, ice formation in a vitrified sample is revealed by Raman scattering. The technology allows us to monitor sample quality during cold storage a...

P-29: Antioxidants Improve The Quality of Cryopreserved SSCs

Background Radiotherapy and chemotherapy could affect spermatogenesis process, so it is important to preserve fertility of patients who suffer from cancer disease. Cryopreservation of SSCs is considered as a helpful procedure for preserving male fertility in cancer patients. It seems that antioxidants can decrease ROS formation and reduce side-effects of cryopreservation on cells. In this study...

Quality Control of Biomarkers: From the Samples to Data Interpretation

control of the optical properties of nanoparticles by laser fields

در این پایان نامه، درهمتنیدگی بین یک سیستم نقطه کوانتومی دوگانه(مولکول نقطه کوانتومی) و میدان مورد مطالعه قرار گرفته است. از آنتروپی ون نیومن به عنوان ابزاری برای بررسی درهمتنیدگی بین اتم و میدان استفاده شده و تاثیر پارامترهای مختلف، نظیر تونل زنی(که توسط تغییر ولتاژ ایجاد می شود)، شدت میدان و نسبت دو گسیل خودبخودی بر رفتار درجه درهمتنیدگی سیستم بررسی شده اشت.با تغییر هر یک از این پارامترها، در...
