Photocrosslinkable Kidney Decellularized Extracellular Matrix‐Based Bioink for 3D Bioprinting

open access: yesAdvanced Healthcare Materials, EarlyView.
A photocrosslinkable bioink is developed from methacrylated decellularized porcine kidney extracellular matrix to create kidney‐specific 3D constructs. This bioink supports high cell viability, promotes multicellular spheroid formation, and enables stable multilayer bioprinting with tunable mechanical properties, providing a versatile platform for ...

Migratory connectivity of Blue-winged Teal: risk implications for avian influenza virus introduction to Cuba

open access: yesFrontiers in Bird Science
In recent years, the complex evolution of the highly pathogenic avian influenza (HPAI) situation reflects a change in the eco-epidemiology of the causative agent which, among other demands, renews the need for better understanding of the connectivity ...

Path integral Monte Carlo calculations of helium and hydrogen-helium plasma thermodynamics and of the deuterium shock Hugoniot

open access: yes, 2006
In this work we calculate the thermodynamic properties of hydrogen-helium plasmas with different mass fractions of helium by the direct path integral Monte Carlo method.

Contact Transfer Epitaxy of Halide Perovskites

open access: yesAdvanced Materials, EarlyView.
Bringing a halide perovskite thin film (donor) into contact with a self‐assembled monolayer of oriented perovskite nanocrystals (acceptor) at elevated temperature leads to epitaxial transfer of halide perovskite from the donor to the acceptor substrate.

Cholesterol absorption efficiency declines at moderate dietary doses in normal human subjects

open access: yesJournal of Lipid Research, 1999
While unphysiologically large cholesterol doses are known to reduce percent cholesterol absorption, smaller amounts are reported to have no effect in human subjects.

Stable Isotopic Evidence of Paleorecharge in the Northern Gulf Coastal Plain (USA)

open access: yesHydrology
Stable isotope abundances (δ18O and δ2H) in regional aquifers can provide important paleoclimate information. However, identifying paleoclimate signals can be complicated by cross-formational mixing and, potentially, by isotopic diffusion between ...

Concurrence in the ability for lipid synthesis between life stages in insects [PDF]

open access: yesRoyal Society Open Science, 2017
The ability to synthesize lipids is critical for an organism’s fitness; hence, metabolic pathways, underlying lipid synthesis, tend to be highly conserved. Surprisingly, the majority of parasitoids deviate from this general metabolic model by lacking the

The N2D+/N2H+ ratio as an evolutionary tracer of Class 0 protostars

open access: yes, 2008
Deuterated ions are abundant in cold (T=10 K), dense (n=10^5 cm^-3) regions, in which CO is frozen out onto dust grains. In such environments, the deuterium fractionation of such ions can exceed the elemental abundance ratio of D/H by a factor of 10^4 ...

Resonant $dd\mu$ Formation in Condensed Deuterium [PDF]

open access: yes, 2001
The rate of $dd\mu$ muonic molecule resonant formation in $d\mu$ atom collision with a condensed deuterium target is expressed in terms of a single-particle response function.
