This study was undertaken to establish baseline data on the chromosomal status of 'failed-fertilized' oocytes derived from in-vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI) procedures. A cytogenetic analysis was undertaken on 162 IVF and 51 ICSI oocytes. In all, 82.1% (133/162) of the IVF and 78.4% (40/51) of the ICSI oocytes had(More)
Psychedelic drugs such as lysergic acid diethylamide (LSD) were used extensively in psychiatry in the past and their therapeutic potential is beginning to be re-examined today. Psychedelic psychotherapy typically involves a patient lying with their eyes-closed during peak drug effects, while listening to music and being supervised by trained(More)
In-house prepared medium was used routinely in our in-vitro fertilization (IVF) facility prior to the introduction of the commercial 'Medi-Cult' products. A comparative study of the in-vitro development of embryos cultured in two [T6 and Earle's balanced salt solution (EBSS)] human-inactivated serum (HIS)-supplemented media from days 0 to 5 showed that(More)
BACKGROUND Depression, a condition commonly comorbid with multiple sclerosis (MS), is associated more generally with elevated inflammatory markers and hippocampal pathology. We hypothesized that neuroinflammation in the hippocampus is responsible for depression associated with MS. We characterized the relationship between depressive symptoms and hippocampal(More)
BACKGROUND The compound 3,4-methylenedioxymethamphetamine (MDMA) is a potent monoamine releaser that produces an acute euphoria in most individuals. METHODS In a double-blind, placebo-controlled, balanced-order study, MDMA was orally administered to 25 physically and mentally healthy individuals. Arterial spin labeling and seed-based resting state(More)
3,4-methylenedioxymethamphetamine (MDMA) is a potent monoamine-releaser that is widely used as a recreational drug. Preliminary work has supported the potential of MDMA in psychotherapy for post-traumatic stress disorder (PTSD). The neurobiological mechanisms underlying its putative efficacy are, however, poorly understood. Psychotherapy for PTSD usually(More)
While magnetic resonance imaging (MRI) data is itself 3D, it is often difficult to adequately present the results papers and slides in 3D. As a result, findings of MRI studies are often presented in 2D instead. A solution is to create figures that include perspective and can convey 3D information; such figures can sometimes be produced by standard(More)
Anecdotally, both acute and chronic cannabis use have been associated with apathy, amotivation, and other reward processing deficits. To date, empirical support for these effects is limited, and no previous studies have assessed both acute effects of Δ-9-tetrahydrocannabinol (THC) and cannabidiol (CBD), as well as associations with cannabis dependence. The(More)
Psilocybin with psychological support is showing promise as a treatment model in psychiatry but its therapeutic mechanisms are poorly understood. Here, cerebral blood flow (CBF) and blood oxygen-level dependent (BOLD) resting-state functional connectivity (RSFC) were measured with functional magnetic resonance imaging (fMRI) before and after treatment with(More)
Cultured human preimplantation embryos have been used to develop methods which allow preimplantation genetic diagnosis (PGD) analyses by polymerase chain reaction (PCR) and fluorescent in-situ hybridization (FISH) on biopsied blastomeres and trophectoderm cells from the same embryo. An experimental design is described and experiments undertaken, which(More)
