Morphometric data on body size and digit ratios of the common spadefoot toad (Pelobates fuscus)
No full textThe dataset includes information on sex, with individuals categorized as male or female, as well as key body size metrics such as snout-to-vent length (SVL), measured from the tip of the snout to the posterior end of the vent, providing an overall estimate of body size, and head width (HW), which represents the maximum width of the head and is useful for assessing allometric relationships and potential differences between sexes. Additionally, individual digit lengths from both forelimbs and hind limbs were recorded, allowing for comparisons of limb proportions. Moreover, the dataset includes digit ratios, calculated from specific digit measurements. The specimens were obtained from an archival collection, located in the Department of Zoology at the Poznań University of Life Sciences. Please note, that for some individuals, the dataset lacks values for digit length and digit ratios in the forelimbs. This is due to some archival specimens having forelimbs in poor condition, making accurate measurement impossible.Data contains a ReadMe.pdf file.</p

Chirped flicker optoretinography for in vivo characterization of human photoreceptors’ frequency response to light
No full textFlicker electroretinography (ERG) has served as a valuable noninvasive objective tool for investigating retinal physiological function through the measurement of electrical signals originating from retinal neurons in response to temporally modulated light stimulation. Deficits in the response at certain frequencies can be used as effective biomarkers of cone-pathway dysfunction. In this Letter, we present the progress we made on its optical counterpart—photopic flicker optoretinography (f-ORG). Specifically, we focus on the measurement of the response of light-adapted retinal photoreceptors to a flicker stimulus with chirped frequency modulation. In contrast to measurements performed at discrete frequencies, this technique enables a significantly accelerated characterization of photoreceptor outer segment optical path length modulation amplitudes in the nanometer range as a function of stimulus frequency, enabling the acquisition of the characteristic frequency response in less than 2 sec.</p

Sex-Dependent Regulation of Liver Fibrosis in Primary Sclerosing Cholangitis: The Role of miR-125b, Androgen Receptors, TGF-β, and Apelin Signalling
No full textThis study explore how hormonal and molecular pathways contribute to the differential progression of liver fibrosis between men and women with PSC.The study focuses on several key molecular players: miR-125b, androgen receptors, TGF-β signaling, and apelin signaling. Through experimental analysis, the authors demonstrate that these factors modulate the fibrotic response in a sex-dependent manner, with implications for how the disease progresses in different genders. miR-125b, a microRNA involved in regulating inflammatory responses, is shown to play a significant role in the fibrotic response, possibly by interacting with androgen receptors.Androgen receptors are highlighted for their involvement in the progression of liver fibrosis, particularly in male patients. The androgen-driven signaling pathways may enhance fibrosis through interactions with other key players, such as TGF-β.TGF-β (Transforming Growth Factor-beta), a critical regulator of fibrosis in many chronic liver diseases, is discussed as a central mediator of fibrosis in PSC, with differences in its expression and activity between sexes.Apelin, an endogenous peptide involved in various physiological processes, is found to modulate fibrosis and liver inflammation in a sex-dependent manner, contributing to the complexity of PSC.The study presents compelling evidence that sex hormones and their associated signaling pathways significantly influence the progression of liver fibrosis in PSC. The findings suggest that therapeutic approaches targeting these pathways, specifically tailored to male and female patients, could provide new avenues for managing PSC more effectively.</p
