Article Abstract
The effect of seasonal variation and lunar cycles on reproductive parameters in dogs is unknown. Lunar cycles have important effects on several biological events. Controversy exists about the influence of lunar cycles on offspring sex ratio. This study examined the sex offspring distribution of 973 puppies (48% females and 52% males) from 150 bitches in Italy between 2015 and 2020. A two-way ANOVA followed by post-hoc -test (Bonferroni correction) was used to analyze the influence of season and lunar phase on offspring sex ratio at conception. Sex offspring distribution was not affected by season, whereas lunar phase had a significant effect (< .05). During the new moon, the proportion of male puppies born was significantly lower than during the full moon phase ( < .05). We conclude that season had no effect on sex offspring distribution. The new moon phase at conception appeared to be related to a lower male sex ratio at birth. Further studies assessing additional factors will help provide a better understanding of the lunar cycle differences observed in the sex ratio distribution of dogs.

Perfluorohexane sulfonic acid (PFHxS) is extensively used in waterproof coatings and fire-fighting foams, and several studies have found it to be a potential health hazard, but there is still unknown about its effects on spermatogenesis. Our results showed that PFHxS-treated mice have significant reproductive toxicity, including a decrease in sperm count and motility, and the levels of sex hormones (P < 0.05).

Fluoride, a common agricultural additive used to enhance plant resilience and pest control, poses toxicity risks when exposure surpasses safe thresholds, affecting ecosystems and human health. While its reproductive toxicity is recognized, the sex-specific and cross-generational effects remain underexplored. To address this gap, we employed an integrative approach combining transcriptomics (next-generation sequencing (NGS)), bioinformatic network analysis, gut microbiota sequencing, and functional assays.

A majority of people with schizophrenia will experience motor symptoms such as impairments to coordination, balance and motor sequencing. These neurological soft signs are associated with negative social and functional outcomes, and poor disease prognosis. They occur prior to medication exposure, suggesting they are an intrinsic feature of schizophrenia.

The role of endogenous cannabinoids (endocannabinoids; eCBs) in cognitive-related processes has been demonstrated in preclinical studies. However, observational studies are lacking. We examined the associations of multiple circulating eCBs and eCB-like molecules with cognitive function in a sample of dementia-free older adults.

Prenatal stress is a risk factor for neurodevelopmental disorders (NDDs), including autism spectrum disorder (ASD). However, how early stress modification of brain development contributes to this pathophysiology is poorly understood. Ventral forebrain regions such as dorsal striatum are of particular interest: dorsal striatum modulates movement and cognition, is altered in NDDs, and has a primarily GABAergic population.
