NO DIFFERENCE IN MATURATION CAPACITY, IN VITRO FERTILIZATION AND PREGNANT RATE OF OOCYTES OBTAINED BY ULTRASOUND-GUIDED OVUM PICK-UP FROM PREGNANT DAIRY COWS AND HEIFERS [PDF]

, 2018
Several lines of evidence assign to the ovarian follicular microenvironment the disparity between the fertility of dairy cows and heifers. This work evaluated the difference in maturation and subsequent embryonic development and pregnancy rate of ...

NPF2 is involved in intracellular pH regulation and ion balance in the diatom Phaeodactylum tricornutum

New Phytologist, EarlyView.
Summary Cellular ion and pH homeostasis are crucial factors affecting and regulating metabolic reactions, protein stability, signalling and transport mechanisms. To balance intracellular ion concentrations, organisms need to constantly sense and respond to both the extracellular environment and cell compartments' requests.

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 ...

Mesenchymal stem cells promote ovarian reconstruction in mice

Stem Cell Research & Therapy
Background Studies have shown that chemotherapy and radiotherapy can cause premature ovarian failure and loss of fertility in female cancer patients. Ovarian cortex cryopreservation is a good choice to preserve female fertility before cancer treatment ...

Description of the ovarian follicle maturation of the migratory adult female Bulatmai barbel (Luciobarbus capito, Güldenstädt 1772) in captivity [PDF]

, 2013
The study aimed to investigate the maturation process of ovarian follicles and ovary structure of migratory form of female Bulatmai barbel (Lucioarbus capito). The histology of oogenesis coincided with that known from most teleosts. The ovarian structure

MCT1‐mediated bidirectional propionate transport across human placental syncytiotrophoblast layer: insights from a trophoblast stem cell‐derived barrier model

The Journal of Physiology, EarlyView.
Abstract figure legend Propionate in the fetal circulation is thought to originate from fermentation of dietary fibre by the maternal gut microbiota. However, the mechanism of transplacental transport has remained unclear. Here, we measured propionate permeability using a placental barrier model generated by differentiating human placental trophoblast ...

Caenorhabditis elegans as an in vivo model system for human inherited primary arrhythmia syndromes

The Journal of Physiology, EarlyView.
Abstract figure legend Most genes involved in inherited primary arrhythmia syndromes (IPAS) are conserved in Caenorhabditis elegans, where genetic manipulation enables functional characterization of variants, identification of regulatory proteins, and in vivo drug testing.

The role of progesterone in the regulation of ciliary activity in the fallopian tube [PDF]

, 2009
The overall aim of this thesis was to investigate the distribution and regulation of membrane progesterone receptors (mPRs) that may be involved in regulating ciliary activity in the fallopian tube.
