Spaceborne and spaceborn: Physiological aspects of pregnancy and birth during interplanetary flight

Experimental Physiology, EarlyView.
Abstract Crewed interplanetary return missions that are on the planning horizon will take years, more than enough time for initiation and completion of a pregnancy. Pregnancy is viewed as a sequence of processes – fertilization, blastocyst formation, implantation, gastrulation, placentation, organogenesis, gross morphogenesis, birth and neonatal ...

Cutaneous eccrine glands of the foot pads of the rock hyrax (Procavia capensis, Hyracoidea, mammalia) [PDF]

, 2002
In order to find correlations between skin gland morphology and specific ethological features, the cutaneous glands of the foot pads of Procavia capensis were studied by histological and various histochemical methods and by electron microscopy.

Morphology of rectum in broiler chicken and domestic fowl: notability of retrograde peristalsis for water preservation

Journal of Applied Animal Research, 2018
Using light and electron microscopy, the rectum-coprodeum (R-C) segment of two species of chickens was examined. Six domestic fowls (Gallus domesticus) and 12 broiler chickens (ROSS 308) with the same ages were chosen for this study.

A primary cell‐based fluidic co‐culture model to investigate drug transport across the human placenta

The Journal of Physiology, EarlyView.
Abstract figure legend Schematic overview of a flow‐driven in vitro model of the human placental barrier designed to study transport processes during pregnancy. The model recreates key features of the maternal–fetal interface, enabling the investigation of how nutrients and therapeutic compounds cross the placental barrier under physiologically ...

Epithelial organization and cyst lumen expansion require efficient Sec13-Sec31-driven secretion [PDF]

, 2012
Epithelial morphogenesis is directed by interactions with the underlying extracellular matrix. Secretion of collagen and other matrix components requires efficient coat complex II (COPII) vesicle formation at the endoplasmic reticulum. Here, we show that

Signal Amplification in the HPT Axis—Evidence for Its Existence, Location, Significance, and Molecular Mechanisms

Acta Physiologica, Volume 242, Issue 4, April 2026.
ABSTRACT Thyroid hormones (THs) are under negative feedback regulation via the hypothalamic–pituitary‐thyroid (HPT) axis. How this axis operates to keep the circulating THs within a narrow physiological range is not well understood quantitatively. Led by the design principle of robust homeostatic feedback control, here we review and synthesize the ...

Continuous growth of proximal tubular kidney epithelial cells in hormone-supplemented serum-free medium. [PDF]

, 1982
An epithelial cell line from pig kidney (LLC-PK1) with properties of proximal tubular cells can be maintained indefinitely in hormone-supplemented serum-free medium. Continuous growth requires the presence of seven factors: transferrin, insulin, selenium,

Serum Villin‐1—A Novel Marker of Gut Barrier Damage in Acutely Decompensated Cirrhosis: A Cohort Study and Validation

Alimentary Pharmacology &Therapeutics, Volume 63, Issue 7, Page 1018-1032, April 2026.
Serum villin‐1 is a non‐invasive indicator of gut barrier damage and short‐term mortality in acutely decompensated cirrhosis. Incorporating villin‐1 assessment into risk stratification methods improves prognostic accuracy by capturing an essential, yet previously overlooked component of disease progression.
