Platelet Biochemistry and Morphology after Cryopreservation [PDF]

open access: yes, 2020
Platelet cryopreservation has been investigated for several decades as an alternative to room temperature storage of platelet concentrates. The use of dimethylsulfoxide as a cryoprotectant has improved platelet storage and cryopreserved concentrates can ...

Structure in the Epislon Eridani dusty disk caused by mean motion resonances with a 0.3 eccentricity planet at periastron [PDF]

open access: yes, 2002
The morphology of the epsilon Eridani dust ring is reproduced by a numerical simulation of dust particles captured into the 5:3 and 3:2 exterior mean-motion resonances with a 0.3 eccentricity 10^-4 solar mass planet at periastron at a semi-major axis of ...

Development of hypobranchial muscles with special reference to the evolution of the vertebrate neck

open access: yesZoological Letters, 2018
Background The extant vertebrates include cyclostomes (lamprey and hagfish) and crown gnathostomes (jawed vertebrates), but there are various anatomical disparities between these two groups. Conspicuous in the gnathostomes is the neck, which occupies the

The damping and structural properties of dragonfly and damselfly wings during dynamic movement

open access: yesCommunications Biology, 2021
Lietz, Rajabi and colleagues investigate the physiological and structural components of damping in insect wings. Notably, flight muscles and hemolyph appear to have no direct involvement in wing damping, compared to the function of the wing hinge.

Numerical model of the spatio-temporal dynamics in a water strider group

open access: yesScientific Reports, 2021
The water strider group demonstrates a very complex dynamics consisting of competition for the food items, territoriality and aggression to the conspecific individuals, escaping from the predators, etc.

Changes in cytoplasmic and extracellular neuromelanin in human substantia nigra with normal aging

open access: yesEuropean Journal of Histochemistry, 2021
Neuromelanin (NM) is a dark polymer pigment produced in certain populations of catecholaminergic neurons in the brain. It is present in various areas of the human brain, most often in the substantia nigra (SN) pars compacta and the locus coeruleus, the ...

Exploring lipid diversity and minimalism to define membrane requirements for synthetic cells

open access: yesFEBS Letters, EarlyView.
Designing the lipid membrane of synthetic cells is a complex task, in which its various roles (among them solute transport, membrane protein support, and self‐replication) should all be integrated. In this review, we report the latest top‐down and bottom‐up advances and discuss compatibility and complexity issues of current engineering approaches ...
