Packed for Ossification: High‐Density Bioprinting of hPDC Spheroids in HAMA Toward Endochondral Ossification

open access: yesAdvanced Healthcare Materials, EarlyView.
Human periosteum‐derived cell spheroids bioprinted at high density within a hyaluronic acid matrix promote fusion and hypertrophic cartilage formation in vitro. Early encapsulation enhances spheroid interaction and matrix maturation, generating scalable cartilage templates intended for endochondral bone regeneration.

MPTP impairs dopamine D1 receptor-mediated survival of newborn neurons in ventral hippocampus to cause depressive-like behaviors in adult mice

open access: yesFrontiers in Molecular Neuroscience, 2016
Parkinson’s disease is characterized by motor symptoms with depression. We evaluated the influence of dopaminergic depletion on hippocampal neurogenesis process to explore mechanisms of depression production.

Hydrological controls on river network connectivity [PDF]

open access: yes, 2019
This study proposes a probabilistic approach for the quantitative assessment of reach- and network-scale hydrological connectivity as dictated by river flow space–time variability. Spatial dynamics of daily streamflows are estimated based on climatic and

The characteristics of collagen‐induced rheumatoid arthritis in macaques and the changes of heart

open access: yesAnimal Models and Experimental Medicine, EarlyView.
The disease progression in CIA macaques was categorized into three stages: IIR (days 14–34): The indicators related to rheumatoid arthritis and the levels of immunoglobulin were all elevated. There was a small amount of joint effusion, edema and mild synovial hyperplasia. No joint swelling was observed by naked eye.

Estimation and rapid identification of later stages during embryonic development of the oviparous lizard Sceloporus aeneus (Squamata: Phrynosomatidae)

open access: yesThe Anatomical Record, EarlyView.
Abstract Stages of embryonic development for reptiles have been presented in tables that may include all or part of embryonic development. When oviposition occurs in some lizards, embryos are already in the later stages of development; likewise, the size of the eggs increases as incubation time progresses.

Supplementation of dairy cows with docosahexaenoic acid did not affect ovarian activity

open access: yesCzech Journal of Animal Science, 2017
The effect of docosahexaenoic acid (DHA) on ovarian activity of dairy cows was determined. Experimental cows (n = 25) were fed a total mixed ration supplemented daily with 100 g/cow of an algae product All-G-Rich (Alltech, Ireland) containing 10% DHA ...

Effect of Cyclic Heat Exposure on the Growth Performance and Metabolism of Broilers Fed Palm Kernel Meal

open access: yesAnimal Research and One Health, EarlyView.
The aim of our study is to evaluate the interaction between HS and the incorporation of PKM in broiler chicken diets, as well as its effect on growth performance and metabolism. Based on the results obtained, PKM supplementation failed to mitigate the adverse effects of heat stress in broiler chickens. ABSTRACT The aim of this study was to evaluate the

A maize polygalacturonase functions as a suppressor of programmed cell death in plants

open access: yesBMC Plant Biology, 2019
Background The hypersensitive defense response (HR) in plants is a fast, localized necrotic response around the point of pathogen ingress. HR is usually triggered by a pathogen recognition event mediated by a nucleotide-binding site, leucine-rich repeat (
