Objective: To undertake a multi-centre study to maximize the number of Makler chambers used.

Methods: A total of 15 laboratories participated with 31 Makler chambers. A suspension of latex beads was prepared to a concentration of 20 millions per milliliter, and 0.5 mL aliquots distributed to each participating laboratory. They measured the concentration on their Makler chamber(s) used for routine semen analysis by adding 3, 4, 5, 7 and 10 μL volumes of bead suspension to the chamber.

Results: There was no difference in within-chamber analysis of the bead concentration according to the volume of bead suspension …

Association Between The G-Protein Β3 Subunit C825t Polymorphism With Essential Hypertension: A Meta-Analysis In Han Chinese Population, Jaipeng Lu, Q Guo, Ling Zhang, Wei Wang

Research outputs 2012

We aimed to evaluate the contribution of the G-protein β3 subunit C825T (GNB3-C825T) polymorphism to essential hypertension (EH) in Han Chinese population by performing meta-analysis. A meta-analysis was performed in 12 case–control genetic association studies including 3,020 hypertension patients and 2,790 controls from MEDLINE (PubMed) and the China National Knowledge Infrastructure platforms. The STATA 10.0 software was used in analysis. Overall, there was no significant association between the GNB3-C825T polymorphism and EH in neither additive [TT vs. CC: OR (95 % CI) = 1.11 (0.74–1.69), P = 0.61; TC vs. CC: OR (95 % CI) = 1.08 (0.89–1.31), P = …

The Fate Of Frozen Human Embryos When Transferred Either On The Day Ofthawing Or After Overnight Culture, Yanhe Liu, Kellie Peirce, Kailin Yap, Kate Mckenzie, Jay Natalwala, Vince Chapple, Margo Norman, Phillip Matson

Research outputs 2012

Objective: To study the performance of thawed zygotes and cleavage stage embryos transferred either on the day of thaw or after overnight culture. Methods: A retrospective study of 864 frozen embryo transfer cycles. Cryosurvival rates per thawed embryo and implantation rates were analysed for embryos frozen on Day 1, Day 2 or Day 3 relative to oocyte collection (Day 0) and transferred on the day of thaw or after overnight culture, together with clinical pregnancy rates and prevalence of multiple gestations. Results: Survival of Day 3 embryos was significantly lower than those frozen on Day 1 (P=0.017) or Day 2 …

Biomedical Image Signal Processing For Reflection-Based Imaging, Paul Jansz, Steven Richardson, Graham Wild, Steven Hinckley

Research outputs 2012

Optical coherence tomography (OCT), ultrasound and other reflection based biomedical imaging technologies involve image signal processing that is primarily a filtering, digitizing and summing process so that the tissue cross-section can be visualized. In particular, in OCT, a series of adjacent one dimensional in-vivo axial interferograms (A-scan) are summed to form a two dimensional (B-scan) reflection map or reflectogram. Further graphical combinations can add adjacent B-scan together to form three dimensional C-scans. A physician can make a subjective interpretation and evaluation from the B and/or C-scans that may lead to actions impacting on the patient’s prognosis. More objective information can …
