Studies of the reproductive biology and of the structure, composition and physiology of the egg of Graphognathus leocoloma Boheman (Coleoptera : Curculionidae): a thesis presented in partial fulfilment of the requirements for the degree of Master of Science in Zoology at Massey University [PDF]

open access: yes, 1977
The published information regarding the biology and pest status of Graphognathus leucoloma Boheman is summarized. A study was made of egg development at temperatures ranging from 4 to 37.8°C and relative humidities ranging from 40 to 100%.

The Life Cycle Relative to Temperature of Protaphorura Armatus (Tullberg) (Collembola: Onychiuridae), a Parathenogenetic Species [PDF]

open access: yes, 2017
Apparent parthenogenetic reproduction in Collembola has sometimes been attributed to accidental transfer of spermatophores with the food material from one culture to another (Schaller, 1953; Mayer, 1957).

Chorion Mesenchymal Stem Cells Show Superior Differentiation, Immunosuppressive, and Angiogenic Potentials in Comparison With Haploidentical Maternal Placental Cells

open access: yesStem Cells Translational Medicine, 2015
Mesenchymal stem cells (MSCs) of placental origin have become increasingly translational owing to their abundance and accessibility. MSCs of different origin share several features but also present biological differences that might point to distinct ...

Dihydroorotate dehydrogenase (DHODH) regulates trophoblast syncytialization through organelle stress–induced cellular senescence

open access: yesFEBS Open Bio, EarlyView.
The inhibition of mitochondrial dihydroorotate dehydrogenase (DHODH) impairs syncytialization and induces cellular senescence via mitochondrial and endoplasmic reticulum stress in human trophoblast stem cells, elevating sFlt1/PlGF levels, a hallmark of placental dysfunction in hypertensive disorders of pregnancy.

Development of extra-embryonic membranes and fluid compartments [PDF]

open access: yes, 2001
An account of the development of extra-embryonic membranes in the embryo of poultry. The roles of these membranes in the transfer of water from albumen to yolk and to embryonic tissue is ...

Comparison of LPS-stimulated release of cytokines in punch versus transwell tissue culture systems of human gestational membranes [PDF]

open access: yes, 2010
Background Cytokine signaling within the amnionic, chorionic and decidual extraplacental gestational membranes plays an important role in membrane rupture and the timing of birth.

Triazine‐Trione Thermosets with High Processability for Scaffold Applications in Bone Tissue Engineering

open access: yesAdvanced Healthcare Materials, EarlyView.
Novel photo‐clickable triazine‐trione thermosets can be shaped and cured under mild conditions, including room and physiological temperatures. These materials are biocompatible and support osteogenic differentiation of bone marrow–derived mesenchymal stem cells on their surface.

Evaluation of the Dual Impact of Nanotechnologies on Health and Environment Through Alternative Bridging Models

open access: yesAdvanced Healthcare Materials, EarlyView.
This review explores how alternative invertebrate and small‐vertebrate models advance the evaluation of nanomaterials across medicine and environmental science. By bridging cellular and organismal levels, these models enable integrated assessment of toxicity, biodistribution, and therapeutic performance.

Using Noninvasive Genetic Sampling to Survey Rare Butterfly Populations

open access: yesInsects, 2019
Advances in nondestructive genetic sampling techniques continue to offer new opportunities for studying organisms, particularly those of conservation concern where more traditional invasive sampling methods are often not available.

In vivo Assessment of Supra-Cervical Fetal Membrane by MRI 3D CISS: A Preliminary Study

open access: yesFrontiers in Physiology, 2020
In approximately 8% of term births and 33% of pre-term births, the fetal membrane (FM) ruptures before delivery. In vitro studies of FMs after delivery have suggested the series of events leading to rupture, but no in vivo studies have confirmed this ...
