“…Each sample was measured using 100 µL of plasma and 50 µL of MNPs. The average plasma viscosity of normal rabbits measured at three magnetic field intensities was 1.098 mPa•s, which was less than 4.5% difference from that of 30-day-old New Zealand white rabbits in the reference [35]. Because there are differences between individual rabbits, this measurement is considered acceptable.…”

Magnetic particle spectrometer (MPS) is the device for characterizing the properties of magnetic nanoparticle (MNP) suspensions, such as viscosity, temperature, and concentration. Specifically, in viscosity measurement, MPS usually works at one or several fixed frequencies. It is challenging to find the appropriate frequency for viscosity measurement of different MNP suspensions. The frequency parameter can be introduced into the measurement method to improve the measurement accuracy. Here, we developed an arbitrary frequency MPS to measure the harmonic amplitudes of the magnetization signals of MNPs, which were generated at various frequencies. A method of measuring the viscosity of MNP suspensions by harmonic ratios at different frequencies was proposed. The viscosity measurement time used in the experiment is 1 s, and the shortest measurement time available is 0.2 s. Experimental results show that the arbitrary frequency MPS can measure the viscosity of samples ranging from 0.77 mPa•s to 3.87 mPa•s, and the average measurement deviation is 2.7%. The method was validated using plasma samples from normal rabbits and high-fat diet (HFD) rabbits. Normal rabbit measurements differed from the reference by less than 4.5%, and the plasma viscosity of normal and HFD rabbits could be clearly distinguished.

“…Therefore, the main reason for increased whole blood viscosity may be due to red blood cell aggregation. Studies have shown that ambient temperature (climate) has an effect on both blood viscosity and plasma viscosity in animals [18][19][20][21]. When the temperature decreases, blood flow slows down, blood viscosity increases, and red blood cell aggregation is enhanced [22][23][24].…”

The giant panda, Ailuropoda melanoleuca, serves as a flagship species for biodiversity conservation, embodying the intersection of ecological, evolutionary, and anthropogenic forces shaping the natural world. Hematological parameters serve as crucial indicators for assessing the physiological status of animals. However, our understanding of blood parameters and hemorheology in captive giant pandas under non-anesthetic conditions is limited. In this study, from September 2018 to August 2020, we collected blood samples from captive giant pandas under non-anesthetic conditions. Twelve captive giant pandas, ranging in age from 2 to 28 years, were divided into three groups based on their age, and the variations in basic blood parameters and hemorheological parameters across four seasons were analyzed. This provided baseline data for future blood sample comparisons in non-anesthetized captive giant pandas. Additionally, we observed seasonal changes in hematological morphology, hemorheology, and serum enzymes. Moreover, seasonality had a regulatory effect on hemorheological parameters and negatively impacted blood viscosity. Age influenced changes in serum enzymes, serum protein content, and serum metabolites, indicating differences in overall metabolic processes among giant pandas of different age groups. Whether factors such as season and climate contribute to environmental stress in captive giant pandas requires further investigation. The findings of this study may help to protect the stability of the giant panda population better and provide a reference for the medical care of captive giant pandas.

“…Neither is it explicidly limited to the utilization of transgenic (mouse) models to mimic human diseases with all the well-known associated challenges nor to use animals as disease models for practical reasons, e.g. ( Thomas et al, 2001 ), but the use of natural genetic and functional heterogeneity of RBCs from various species such as the elliptic camel RBCs as models for elliptocytosis ( Smith et al, 1979 ; Amin and Sirs, 1985 ; Windberger et al, 2018 ; Baier et al, 2021 ), naturally sickling RBCs of deer, sheep, goat, genets and mongoose, Gulf toadfish, iguana, snakes, or fishes for sickle cell disease ( Steinberg, 2019 ), cow and sheep RBC as models for lipid alterations ( Engen and Clark, 1990 ; Nouri-Sorkhabi et al, 1996 ; Ivanov, 2007 ), and cattle ( Inaba et al, 1996 ; Jay, 1996 ) or even lamprey ( Cameron et al, 2000 ) RBCs as a model of Band 3 protein deficiency. We are looking forward to it.…”

Editorial on the Research Topic Comparative biology of red blood cellsOur interest in the broad diversity of red blood cell (RBC) sizes, composition, gas transport strategies, rheological properties, and metabolism across the animal kingdom is fueled by several reasons. Biologists follow the developmental and evolutionary aspects of this RBC diversity that enables the hosts to survive and populate habitats that vary in O 2 concentration and nutritional abundance matching energy supply and demand (Nikinmaa, 1990). Translational researchers view animals as models to study human diseases, although numerous studies urge for care in translation of the findings obtained using rodents or other mammals as well as insects, nematodes and fishes to the human patients (
