The chemical stability of repository compounds is affected by various environmental conditions during long-term storage. Studies were carried out to evaluate the effects of the following potential causes of instability of compounds in DMSO at a 10-mM concentration: water, oxygen, freeze/thaw cycles, and storage container material. A set of compounds was selected for the study based on structura...

The study was conducted to determine the influence of D-aspartic acid (D-Asp) as antioxidant supplement and thawing rates on ram sperm motility, membrane integrity, abnormality, viability, mitochondria activity, malondialdehyde and antioxidant activities, and total antioxidant capacity after freezing-thawing process. Semen samples from five mature rams (3-4 years old) were diluted with extender...

The worldwide microplastics pollution is a serious environmental and health problem that currently not effectively mitigated. In this work we tested jellyfish mucus as new bioflocculent material capable of sequestration polystyrene in aqueous environments. Mucus was collected from different species used to trap fluorescently tagged microspheres. efficiency removal using varying concentrations m...

The efficacy of IVF for treating human infertility has only a final efficacy index and that is the achievement of a delivery. However, with the evolution of the freeze-all strategy, a new problem is arising, for quantifying the performance of an embryological team. As apart from the efficacy of the management of fresh gametes and embryos, we shall furthermore calculate the efficacy of the freez...

The freezing-thawing effect on the meat quality of whole, gutted and fillets of sea bass (Dicentrarchus labrax) were investigated. It was aimed to investigate the changes in the meat quality of whole, gutted and fillets of sea bass in multiple frozen (-18±2ºC) and thawed cycles in refrigerated conditions (4±2°C). The meat quality assessment of the sea bass groups (whole, gutted and fillets) sub...

As an important type of soil erosion, freeze-thaw erosion occurs primarily at high latitude and altitude. The overview on the effect was provided. Soil affected by processes, as thawing water reinforce each other. Remote sensing provided unprecedented approach for characterizing timing, magnitude, patterns large-scale changes. Furthermore, essence freeze thaw moisture in pores soil. Freeze-thaw...

BACKGROUND AND OBJECTIVES Cord blood (CB) is a valuable source of stem cells. Most CB units are still cryopreserved in single bags in the world's CB banks. Thawing a single CB unit, dividing it into two parts, expanding the smaller one and refreezing the other would optimize ex vivo expansion of CB progenitors prior to transplantation: expanded and unexpanded cells could be infused together to ...
