Background: Modern assisted reproductive technology (ART), including pre-implantation genetic testing for aneuploidy (PGT-A), has opened new avenues in understanding early embryonic events and has simultaneously raised questions about the impact of ART itself on sex ratios.

Aims: The primary aim was to investigate whether patient demographic characteristics, ovarian stimulation protocols or laboratory characteristics in ART influence sex ratios. The secondary aim was to relate the blastocyst sex ratio (BSR) to the corresponding secondary sex ratio (SSR) in our patient cohort.

Mice Lacking the Serotonin Transporter do not Respond to the Behavioural Effects of Psilocybin.

Eur J Pharmacol

January 2025

Florey Institute of Neuroscience and Mental Health, Melbourne Brain Centre, University of Melbourne, Parkville, Australia; Faculty of Medicine, Dentistry and Health Sciences, University of Melbourne, Parkville, Australia. Electronic address:

Background And Purpose: Psilocybin is a serotonergic psychedelic with therapeutic potential for several neuropsychiatric disorders, including depression and anxiety disorders. Serotonin-transporter (5-HTT) knockout mice (KO) are a well-validated mouse model of anxiety/depression and are relevant to both chronic treatment with serotonin transporter reuptake inhibitors (SSRIs) and polymorphisms in the serotonin transporter-linked polymorphic region (5-HTTLPR) associated with depression/anxiety and resistance to classic antidepressant treatments. However, there is yet to be a study assessing the effect of psilocybin in 5-HTT KO mice.

Future directions in the evaluation and management of newly diagnosed metastatic cancer.

Crit Rev Oncol Hematol

January 2025

Department of Radiation Oncology, University Hospitals Seidman Cancer Center, Case Western Reserve University School of Medicine, Cleveland, OH, USA. Electronic address:

There is a much debate regarding optimal selection in patients with metastatic cancer who should undergo local treatment (surgery or radiation treatment) to the primary tumor and/or metastases. Additionally, the optimal treatment of newly diagnosed metastatic cancer is largely unclear. Current prognostication systems to best inform these clinical scenarios are limited, as all metastatic patients are grouped together as having Stage IV disease without further incorporation of patient and disease-specific covariates that significantly impact patient outcomes.

Female agency and probable depression in the perinatal period and beyond: Longitudinal findings from rural Pakistan.

Soc Sci Med

January 2025

Department of Epidemiology, Gillings School of Global Public Health, University of North Carolina, 135 Dauer Drive, Chapel Hill, NC, 27599, USA; Carolina Population Center, University of North Carolina, 123 W Franklin Street, Chapel Hill, NC, 27516, USA.

In Pakistan, a setting with high gender inequality, the relationship between female agency and mental health has not been studied longitudinally or beyond a defined life stage like pregnancy. Using data from the Bachpan cohort of mother-infant dyads in Pakistan, we investigated female agency and depression at two life stages: perinatal (third trimester to 6-months postpartum; n = 1154) and beyond (3- to 4-years postpartum). Modified Poisson models estimated adjusted prevalence ratios (PR) for probable depression (PHQ-9) associated with female agency (freedom of movement and participation in household decision-making) at the two life stages.

Electronic address:

Cultivated meats are typically hybrids of animal cells and plant proteins, but their high production costs limit their scalability. This study explores a cost-effective alternative by hypothesizing that controlling the Maillard and lipid thermal degradation reactions in pure cells can create a meaty aroma that could be extracted from minimal cell quantities. Using spontaneously immortalized porcine myoblasts and fibroblasts adapted to suspension culture with a 1 % serum concentration, we developed a method to isolate flavor precursors via freeze-thawing.

Estimating self-performance when making complex decisions.

Sci Rep

January 2025

Centre for Brain, Mind and Markets, Faculty of Business and Economics, The University of Melbourne, Melbourne, Australia.

Metacognition, the ability to monitor and reflect on our own mental states, enables us to assess our performance at different levels - from confidence in individual decisions to overall self-performance estimates (SPEs). It plays a particularly important part in computationally complex decisions that require a high level of cognitive resources, as the allocation of such limited resources presumably is based on metacognitive evaluations. However, little is known about metacognition in complex decisions, in particular, how people construct SPEs.
