Multi-Task Gaussian Processes and Dilated Convolutional Networks for Reconstruction of Reproductive Hormonal Dynamics [PDF]

arXiv, 2019
We present an end-to-end statistical framework for personalized, accurate, and minimally invasive modeling of female reproductive hormonal patterns. Reconstructing and forecasting the evolution of hormonal dynamics is a challenging task, but a critical one to improve general understanding of the menstrual cycle and personalized detection of potential ...

Novel behavioural assays reveal sex‐specific behavioural syndromes in anemonefish

Journal of Fish Biology, EarlyView.
Abstract Individual differences in behaviour and behavioural plasticity have been extensively studied in a variety of animals across the phylogenetic spectrum. Amphiprion species bring distinct insight into the topic because of their unique life history, mating system, and extraordinary degree of behavioural plasticity associated with protandrous (male‐

Prematuration differences in male and female Atlantic cod: Investigating sex ratio, length and ecotype disparities in juveniles

Journal of Fish Biology, EarlyView.
Abstract Sexual size dimorphism (SSD) and skewed sex ratios are common in the animal kingdom, and marine fishes, such as the Atlantic cod (Gadus morhua), are no exception. This study utilized newly discovered sex‐linked genetic markers to investigate young‐of‐the‐year cod in the Skagerrak system, comprising approximately 2700 individuals from North Sea

Faecal steroid measurements for the assessment of reproductive function in Japanese quail (Coturnix coturnix japonica) and kakapo (Strigops habroptilus) : a thesis presented in partial fulfilment of the requirements for the degree of Master of Science in Physiology at Massey University [PDF]

, 2002
The kakapo (Strigops habroptilus) is an endangered parrot endemic to New Zealand and little is known of its reproductive physiology. Reproductive function is conventionally determined by the measurement of reproductive steroids in plasma samples. This is

Estrogenic regulation of hippocampal inhibitory system across lifespan

Journal of Neuroendocrinology, EarlyView.
Abstract Estrogens produced in peripheral tissues and locally in the brain are potent neuromodulators. The function of the hippocampus, a brain region essential for episodic memory and spatial navigation, relies on the activity of ensembles of excitatory neurons whose activity is temporally and spatially coordinated by a wide diversity of inhibitory ...

Vertebrate endocrine disruptors induce sex-reversal in blue mussels

Scientific Reports
Mollusks are the second most diverse animal phylum, yet little is known about their endocrinology or how they respond to endocrine disrupting compound (EDC) pollution. Characteristic effects of endocrine disruption are reproductive impairment, skewed sex

Perturbations in Lineage Specification of Granulosa and Theca Cells May Alter Corpus Luteum Formation and Function [PDF]

, 2019
Anovulation is a major cause of infertility, and it is the major leading reproductive disorder in mammalian females. Without ovulation, an oocyte is not released from the ovarian follicle to be fertilized and a corpus luteum is not formed.

The gut‐microbiota‐brain axis: Focus on gut steroids

Journal of Neuroendocrinology, EarlyView.
Abstract There are over 1000 varieties of steroids that have been reported in nature, including the endogenous sex steroid hormones (i.e., progesterone, testosterone, and 17β‐estradiol) and corticosteroids which are mainly synthesized by gonads and adrenals, respectively.
