Ectopic breast tissue (EBT) represents a congenital anomaly caused by incomplete regression of mammary ridges at the time of embryonic development. Typically, EBT presents along the mammary line, although usually in the axillary region, it has been located occasionally in unusual sites such as the vulva. Though relatively rare, it is generally subject to a wide range of pathologies that afflict normal breast tissue, encompassing both benign and malignant transformations.

The annual flood pulse is a defining feature of Amazonian floodplain lakes, creating a highly variable environment that influences resource availability, such as food and habitat. These cyclical changes necessitate a high degree of adaptability among fish species, many of which have evolved specialized strategies to cope with the fluctuating conditions. In 2023, the Amazon basin experienced a record-breaking drought event, leading to mass mortality of Amazonian fish and other wildlife.

Wnt7a-Cre is a commonly used for generating uterine epithelial conditional knockout mice, such as epiERα-/- (Esr1f/-Wnt7aCre/+) and epiPR-/- (Pgrf/-Wnt7aCre/+). We noticed that epiERα-/- females, but not epiPR-/- females, have prolonged plugging latency, which is the duration between continuous cohabitation and detection of the first vaginal plug (a sign of mating). Mating occurs in proestrus and/or estrus stages of the estrous cycle.

Traumatic brain injury (TBI) is a serious public health concern and is one of the major causes of death and chronic disability in young individuals. Sleep-wake disturbances are among the most persistent and debilitating consequences of TBI and are reported by 50%-70% of TBI patients regardless of TBI severity. Excessive daytime sleepiness, fatigue, hypersomnia, and insomnia are the most common sleep disturbances in TBI patients.

Vitamin D is essential for healthy skeletal growth and is increasingly recognised for its role in chronic disease development, inflammation and immunity. 25-hydroxyvitamin D (25(OH)D) concentrations are an indicator of vitamin D status and are normally analysed in plasma or serum samples in clinical settings, while archaeological studies rely on the identification of skeletal markers of vitamin D deficiency, such as rickets. Here, we determined 25(OH)D concentrations in hair specimens ('locks') that had been sampled close to the root, aligned by cut end, and sliced into sequential segments from participants (n = 16), from Aberdeen, Scotland, using a modified protocol designed to minimise sample size.
