Pre‐analytical optimization of cell‐free DNA and extracellular vesicle‐derived DNA for mutation detection in liquid biopsies

open access: yesMolecular Oncology, EarlyView.
Pre‐analytical handling critically determines liquid biopsy performance. This study defines practical best‐practice conditions for cell‐free DNA (cfDNA) and extracellular vesicle–derived DNA (evDNA), showing how processing time, storage conditions, tube type, and plasma input volume affect DNA integrity and mutation detection.

Tribological Studies on Scuffing Due to the Influence of Carbon Dioxide Used as a Refrigerant in Compressors [PDF]

open access: yes, 2003
The refrigeration and air conditioning industry has expressed a great interest in the use of carbon dioxide (CO2) as a refrigerant. CO2 is anticipated to replace HFC refrigerants, which are known to have a negative effect on the environment. The reason

Performance analysis of vapor compression refrigeration system using mixed refrigerant R410A

open access: yesInternational Journal of Energy Applications and Technologies, 2021
Mixed refrigerants are obtained from mixing pure refrigerants in specific proportions and it is known as mixed refrigerants. Mixture refrigerants are divided into two groups according to their thermodynamic behavior: zeotropic mixtures and azeotropic mixtures.

Screening and epitope characterization of Nidogen‐2‐specific nanobodies

open access: yesFEBS Open Bio, EarlyView.
Camel immunization and phage display were employed to generate high‐affinity VHH nanobodies against Nidogen‐2. After library construction, biopanning, ELISA screening, sequencing, and recombinant expression, selected nanobodies were purified and characterized, leading to the preliminary exploration of a nanobody‐based sandwich ELISA for specific ...

Improving the energy effectiveness of domestic refrigerators by the application of mixed refrigerants [PDF]

open access: yes, 1978
A critical review of U.S. and foreign literature on the use of a mixture of refrigerants rather than a single one in a refrigeration unit indicates that energy can be conserved in properly arranged systems. An independent analytical study performed under the current contract using a 50% mixture of R-12 and R-114 in a two-evaporator refrigerator typical

Calculation of the operating mode of the mixing refrigerator

open access: yesIOP Conference Series: Earth and Environmental Science, 2018
This article considers the calculation of a mixing refrigerator (contact refrigerator) taking into account the absorption of gaseous components. Calculation of operating mode and definition of optimal operating conditions of the machine that provides the given final gas temperature is carried out.

Zein‐Based Adhesives: Sustainable Extraction and Application in Bioadhesive Technologies

open access: yesAdvanced Engineering Materials, EarlyView.
Zein is extracted from corn gluten meal using a simple and scalable process with high yield (~90%). The resulting protein is applied in bioadhesives modified with Ca2+ and Fe3+ ions, exhibiting substrate‐dependent adhesion. The findings demonstrate competitive bonding performance and highlight the role of ionic interactions in tuning adhesion ...
