The role of thin filament sarcomeric proteins tropomyosin 1 and cardiac troponin T in the developing heart
Published 2016“…However, the sarcomere appeared normal in this treatment group. Stereological analysis also revealed normal cardiac proportions except for the atrial chamber, which was reduced in size. …”

The impact of passive immunisation against BMPRIB and BMP4 on follicle development and ovulation in mice
Published 2015“…The aim of this study was to investigate the role of bone morphogenetic proteins (BMPs) in the regulation of folliculogenesis in mice passively immunised against BMP receptor 1B (BMPRIB) and BMP4. While a stereological study revealed that the numbers of primordial follicles in immunised mice were significantly higher when compared with control animals, treatment with equine chorionic gonadotrophin showed no effect. …”

Ovarian follicle development in Booroola sheep exhibiting impaired bone morphogenetic protein signalling pathway
Published 2009“…Whole sheep ovaries at Q1 the time of birth, 1.5 and 5 years old were collected and processed for the follicle quantification, usingcomputerised stereological methods and statistical analyses. At birth, the total number of primordial follicles in Booroola sheep wassignificantly lower than in merino sheep. …”

The Effects of Progesterone on Hypoxic Ischemic Injuries in the Cornu Ammonis (CA) Region of the Hippocampus of Neonatal Rats
Published 2015“…Cells density and number of pyramidal cells of the hippocampal Cornu Ammonis (CA) regions were examined by stereological methods. The histomorphometric assessment of the effects of progesterone showed minimal but no significant protective value in the volume, cells density and total number of pyramidal cells of hippocampal CA region of the treatment and control groups (p>0.05) after HI. …”

Effect of altered haemodynamics on the developing mitral valve in chick embryonic heart
Published 2017“…Although normal valve morphology was found in HH26 outflow tract banded hearts, smaller and dysmorphic mitral valve primordia were seen upon altered haemodynamics in histological and stereological analysis at HH29 and HH35. A decrease in apoptosis, and aberrant expression of a shear stress responsive gene and extracellular matrix markers in the endocardial cushions were seen in the chick HH29 outflow tract banded hearts. …”

MRI of foetal development
Published 2012“…Here, foetal organ volumes, foetal and placental volume, shoulder width and foetal length were measured using a semiautomatic approach based on the concept of edge detection and a stereological method, the Cavalieri technique. The data shows that maternal smoking has significant negative effect on foetal organ growth and foetal growth, predominantly foetal kidney and foetal volume. …”

The role of abnormal haemodynamics and cardiac troponin T in cardiogenesis
Published 2017“…Upon alteration of haemodynamics, enlargement of the heart with a spectrum of cardiac anomalies were found (e.g ventricular septal defects, thickened epicardium and dysmorphic atrioventricular valves) upon morphological and stereological analysis. A study of global differential expression of OFT-banded hearts by RNA sequencing revealed a number of differentially expressed genes and they were associated with cardioprotection, metabolism, shear stress and valve development; further, a reduction of apoptosis was seen in these banded hearts as well. …”
